1. Executive summary

This report is the result of a project commissioned jointly by Health Commission Wales

(HCW) and the Welsh Ambulance Services NHS Trust (WAST) to review the adequacy of

the funding of WAST in order to meet its current performance targets and at the same time

to establish whether there were opportunities for WAST to improve the efficiency of its

operations.

In Section 3 of the report we outline emerging best practice in the delivery of ambulance

services and the role that the ambulance service can play in the delivery of an integrated

urgent care service. WAST is the only organisation that provides urgent care services on a

day to day basis across the whole of Wales and as such is uniquely well placed to play a

central role in the development of this new model of service delivery. Moreover, we believe

that by adopting this new model it should be possible for WAST to achieve significantly

improved standards of response and patient care relative to the standards that are currently

being achieved.

In Section 4 we set out the findings of our analysis of the efficiency and effectiveness of

WAST and our assessment of the additional resource and funding that WAST will need if it is

to meet all its key performance targets.

Section 5 of the report sets out our conclusions and our recommendations in relation to the

actions that we believe are required by the key stakeholders to enable WAST to provide a

service that compares favourably with the best performing ambulance trusts in the rest of the

United Kingdom.

The principal findings from our analysis are as follows.

WAST‟s performance in relation to the Category A 8 minute target has improved

significantly since the beginning of 2007. However there has been little or no

improvement during this period in relation to the Category A and Category B

14/18/21 minute standards

Although Wales covers a larger geographical area than other ambulance trusts in the

UK, the proportion of EMS activity that occurs in towns and cities in Wales is similar

to that of comparable ambulance trust areas in England

Wales experiences a relatively high number of 999 calls per head of population and a

relatively high proportion of these calls result in a patient being transported to

hospital. This results in pressure being placed on WAST and on hospitals in Wales

that we believe could be alleviated if suitable call triage and assessment procedures

were used and alternative care pathways were available for patients

We estimate that the total cost that WAST incurred in providing the EMS service in

2008-9 was £101.3 mil. WAST received £95.6 mil of funding for the EMS service in

2008-09 from HCW, NLIAH and the Air Ambulance Charity. The difference was

funded by income for other purposes e.g. ARRP

Hospital delays have a significant impact on the ability of WAST to meet its

performance targets. During the reference period for our review, WAST would have

required an additional 900 ambulance hours per week in order to compensate for the

delays in handing over patients at hospital at an annualised cost of £2.3 mil per year.

This effect is of particular significance in the South East region of the Trust.

WAST‟s performance with respect to the initial phase of allocating a vehicle to a 999

call compares poorly with other ambulance trusts in England. A significant

contributory factor to this performance gap is the lack of an Automated Vehicle

Location System (AVLS) and related mobile data systems on EMS vehicles in Wales.

This makes it difficult for WAST reliably to locate and deploy the most appropriate

vehicle to respond to a 999 call.

Once the benefits of its investment in AVLS and mobile data are available, WAST

could meet the current Category A 8 minute targets both at a national and LHB level

with its current staffing levels and overtime rates and with the level of hospital delays

that occurred during the reference period for this review. In order to do this WAST

would need to accelerate the implementation of a deployment strategy that

o is based on 7 minute deployment areas in the more densely populated areas

o matches resource more precisely to the location of activity

o relies more extensively on the use of single manned response vehicles, and

o makes more extensive use of Community First Response schemes in less

densely populated areas as the initial response to Category A incidents.

The current level of staffing does not allow WAST to meet the 14/18/21 minute

standards and also requires a reliance on high levels of overtime to fill core shifts. In

addition, the shortage of staff in certain areas is preventing WAST from undertaking

sufficient ongoing professional training. Based on WAST‟s current levels of overtime

and planned level of relief, we estimate that the cost of the additional staff required to

meet the current 14/18/21 minute performance standards would be £3,744,000. This

would rise to £8,647,000 if WAST were to operate with no reliance on overtime to

cover shifts and with the level of cover for holidays, sickness, training and other lost

hours that was recommended in a Department of Health paper published in April

2007 setting out best practices in managing ambulance trusts.

If it were fully resourced in accordance with the recommendations in this report,

WAST should be able to achieve a Category A 8 minute performance target of at

least 70% for the whole of Wales as well as meeting all the 14/18/21 minute

standards.

The current practice with respect to the 14/18/21 minute standards means that

WAST sends more double staffed ambulances in response to lower acuity 999 calls

than occurs at some other ambulance trusts. As advocated in this report, an

alternative approach which distinguishes more clearly between the requirement for

an appropriate initial assessment of the patient‟s requirements and the subsequent

provision of transportation once it has been determined that the patient needs

transporting to hospital could significantly reduce the number of ambulance hours

that WAST requires and also reduce the number of cases where the patient is

transported to hospital. It should be noted however that a change of this type will

require a significant change in practice within WAST as well as actions by other

stakeholders to ensure that alternative pathways are available for patients.

Consequently the benefits from this change are likely to take between 3 and 5 years

to be fully realised.

If WAST were able to match the levels of ambulance attendance and transportation

that are achieved in some trusts in England it could reduce the number of ambulance

hours required by around 410 per week by comparison with the level that was

planned in 2008/9. This would save around £1,025,000 per year in staff costs

If hospital handover times were improved so that only 10% of hospital handovers

took longer than 15 minutes this would reduce the number of ambulance hours

required by comparison with the reference period for this review by 710 per week .

This would save a further £1,966,000 per year.

If WAST were able to obtain the full benefits from lower ambulance attendance rates

and reduced hospital delays it should be possible for the Trust to meet both the AOF

Category A 8 minute targets and the 14/18/21 minute standards with a staff cost that

would be £1,876,000 lower than the level in 2008/9 based on the current overtime

and planned relief levels and would be £2,497,000 higher than the 2008/9 levels

based on the lower overtime and higher relief scenario.

If WAST were to change its operating model in the way that is advocated in this

report and was also able to obtain the full benefits of lower ambulance attendances

and reduced hospital delays outlined above, it should also be able to realise savings

of up to £280,000 in fleet costs as a result of greater use of cars and less use of

double staffed ambulances.

WAST may also be able to realise additional savings in the following areas

o reducing its administrative overheads

o reducing the number of operating centres and control rooms

It should however be noted that we have not examined these areas in any detail

during this review.

In addition to the detailed findings of our analysis set out above, we have also identified a

number of organisational issues which we believe need to be addressed if WAST is to

achieve a successful transition to the new approach to the delivery of its services that is

advocated in the report. In particular

The challenges of agreeing a common vision between WAST and its many

stakeholders about the role that WAST should play in the delivery of urgent care

across Wales has previously made it difficult for the Trust to plan its future direction

with any certainty and to communicate this to its staff. At the time of this review,

Page 6: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

6

WAST has submitted a vision statement to NHS Wales for comment and

consideration and is also working with the seven new LHBs to include key objectives

within the LHBs own Urgent Care Plans. This offers an opportunity to establish a

jointly agreed role for WAST that will form the basis for the implementation of the

recommendations in this report

The geographical spread of the Trust, the requirement for senior management to be

located in three different regional centres and the amount of change in the senior

management team has made it difficult to establish a stable management structure.

The new management structure that has recently been introduced provides a

framework within which WAST can create the senior management team that will be

required to implement the strategy that is recommended in this report

The quality of clinical oversight, supervision and training has not had sufficient focus

at a time when the Trust has been under pressure to deliver performance. This has

been recognised by WAST and a number of initiatives are currently under way to

address these issues. However, the pressure on resource and the low levels of relief

continue to make it difficult for the Trust to release staff to undertake appropriate

levels of clinical training

The funding arrangements for WAST have been unclear in the past and require

clarification in the new NHS structure so that the link between funding and service

delivery can be made transparent

The current commissioning and performance management arrangements for WAST

do not facilitate clear lines of accountability between WAST and its commissioners

and performance managers for the delivery of the EMS service

Although WAST could achieve the AOF Category A 8 minute target for the initial

attendance at life threatening incidents with its current resource based on best

practice call cycle performance and the current levels of overtime and relief, the

current level of recurring funding that WAST receives is insufficient to enable it to

achieve the 14/18/21 minute standards. We therefore believe that WAST will require

additional funding in the short term in order to provide a fully effective EMS service

that delivers appropriate levels of clinical care to patients

From our discussions with both WAST and HCW we understand that many of the issues that

we have highlighted in this report arise from the previous structure of the NHS in Wales and

are already being addressed. In particular, the new structure for the LHBs provides a

significant opportunity to establish a jointly agreed strategy and role for WAST within the

urgent care system in Wales. We are confident that the implementation of the approach that

is recommended in this report will enable WAST to provide the people of Wales with

standards of care from their ambulance service that are comparable with the best standards

that are achieved elsewhere in the United Kingdom.

2. Background to the Review

2.1. Introduction

Since its establishment in 1998 there has been a history of performance issues at WAST. In

2006, as a result of widespread concerns about the way in which the Trust was being

managed and its failure to meet the performance targets set for it by the Welsh Assembly

Government, the Wales Audit Office was commissioned to produce a report into the

problems that the Trust was facing and a new Chief Executive - Mr Alan Murray - was

appointed to run the Trust. The Audit Office Report which was published in December 2006

identified a large number of areas of concern relating to the way that the Trust had

previously been managed and made a number of recommendations for improvements.

Following the publication of this report, a significant number of changes were successfully

introduced by the new management team and a follow up review by the Audit Office

published in June 2008 found that significant progress that had been made in a number of

areas resulting in clear improvements in performance against the required targets and

standards. In particular performance with respect to the Category A 8 minute target had

improved by around 10 percentage points and performance in relation to GP Urgent

journeys had also improved. However, there had been litlle or no improvement in

performance with respect to the standards for attendance by an ambulance within 14/18/21

minutes.

Subsequent to the publication of the follow up report, there have been further discussions

between WAST and HCW about the actions that the Trust needs to take in order to address

the issues identified by the Audit Commission and the resources that it requires to meet the

current performance standards on a consistent basis. In particular WAST expressed

concerns that its current level of funding was insufficient to allow it to maintain the level of

resource that would be required to meet the current performance standards in view of the

particular challenges that it faces as a Trust – including in particular the problems caused by

extended hospital delays in certain parts of Wales. At the same time Heath Commission

Wales was concerned to establish whether WAST was adopting best practice with respect to

the effectiveness and efficiency of its operational, clinical and financial processes.

Consequently HCW and WAST agreed to jointly commission this review to establish

how WAST‟s performance and cost efficiency compares with that of other

comparable ambulance trusts in the rest of the United Kingdom

the level of resource that WAST requires in order to meet the required AOF targets

and performance standards,

the potential for obtaining cost savings from operating in a more efficient way, and

the opportunities that might exist for WAST to contribute to a more efficient and

effective delivery of unscheduled care services from adopting emerging best

practices in the delivery of ambulance services as seen elsewhere in the United

Kingdom.

2.2. The EMS Service in Wales

The role of the EMS service at WAST has three components

To respond within the required time to 999 calls received by the Trust

To respond to requests from doctors to transport to hospital patients whose doctor

has determined that they need admission

To transport patients from hospital or between hospitals where the hospital

determines that the patient requires a double staffed ambulance for the joiurney in

question

On average in 2008/9 WAST responded to 5750 999 emergency incidents, 1020 urgent

incidents and 210 transfers each week.

At the outset, 999 calls are categorised into three categories of urgency by the calltaker

using a telephone based triage system called the Advanced Medical Priority Dispatch

System (AMPDS) as follows

Category A - immediately life threatening condition/injury

Category B - serious but not life threatening condition/injury

Category C - neither life threatening or serious condition / injury

In the first quarter of 2009 the percentage of 999 incidents to which WAST responded in

each category were as follows

Category A – 41%

Category B - 43%

Category C - 16%,

The response to an emergency incident has the following two components,

an initial response to provide immediate attention and to establish what the patient‟s

requirements are and if appropriate

the provision of transportation to hospital – in most cases in a fully equipped double

staffed emergency ambulance.

In Wales in the first quarter of 2009, 72% of all 999 incidents resulted in a patient being

transported to hospital.

With effect from 1 April 2009, WAST is required to meet the following performance targets in

relation to its EMS service, as detailed in the Annual Operating Framework (AOF)

1. 65% of all Category A incidents across Wales must be responded to by a suitable

responder within eight minutes of the chief complaint being verified by the calltaker

and a minimum level of 60% must be achieved in every LHB area. This target has to

Page 9: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

9

be met on a month-by-month basis as well as on a year-to-date basis. This response

target is important in cases such as heart attacks where early resuscitation is

provided. The type of response can be a fully equipped ambulance, a Rapid

Response Vehicle (RRV), an emergency services co-responder, for instance Fire

and Rescue Service and the Police, or a Community First Responder scheme.

In addition to these AOF targets there are standards which were set for Wales in 1999

for the response times of ambulance crews capable of transporting the patient to

hospital, where the first responder was not an ambulance crew. Whilst these are not

AOF targets they are standards that are aimed at in order to ensure that there is a

suitably equipped ambulance at the scene of the incident to support on scene care and

transport appropriate patients to hospital or other services. These standards are

2. 95% of all Category A incidents must also be attended by a fully equipped

emergency ambulance within a specified time of the start of the incident which is set

at 14 minutes in Cardiff, 21 minutes in Powys, Ceredigion, Gwynned and Anglesey

and 18 minutes elsewhere in Wales

3. 95% of all Category B incidents must be attended by a fully equipped emergency

ambulance within the 14/18/21 minute time period from the start of the incident

4. 95% of all Urgent calls must be in hospital within 15 minutes of the time when the

doctor specified that the patient should arrive

Over the year to 31 March 2009, WAST achieved a performance level of 60.7% across

Wales for Category A performance at 8 minutes, 85.07% for Category A performance at the

14/18/21 minute standard and 78.55.% for Category B performance at the 14/18/21 minute

standard.

The rest of this report analyses the factors that affect WAST‟s ability to meet these targets

and standards, identfies the resources that would be required to achieve these goals and

suggests how WAST might be able to change its practices in a manner that delivers better

results for patients in Wales while enabling WAST to adopt a more cost effective operating

model

2.3. The structure of the review

Our review consisted of the following four complementary work streams:

1. A benchmarking exercise that compared WAST‟s performance and efficiency based

on a number of selected indicators with two broadly comparable English ambulance

trusts – South Western Ambulance Service Trust and East of England Ambulance

Service Trust

2. An analysis of the demand profile to which WAST is required to respond together

with a review of the deployment strategy and rota structure by comparison with best

practice in other ambulance trusts to assess the extent to which performance could

be improved by enhanced operating procedures and the extent to which additional

resource might be required in order to meet the performance standards. The

reference period for this analysis was a 13 week period from 3 November 2008 to 2

February 2009.

3. A review based on structured interviews of the effectiveness of WAST‟s processes

and systems, and current operational and clinical procedures together with a review

of the current commissioning practices.

4. An analysis of the fully loaded costs that WAST incurs in providing the EMS service,

an analysis of the way in which WAST uses its income to fund the EMS service and a

comparison of the current cost model with good practice both in ambulance trusts

and in other organisations.

3. The emerging role of ambulance services in the delivery

of unscheduled care

3.1. Emerging best practice in ambulance services

The ambulance service is an integral part of a healthcare system that exists to meet patients‟

needs when they have an unplanned medical emergency. In order to provide this service in

the best interests of the patient it is highly desirable that ambulance services are planned

and delivered in the context of an overall plan for the provision of unscheduled care services.

In this context, the provision of both ambulance response and other elements of the

unscheduled care system have been the subject of a number of reviews in recent years with

a view to making the provision of care more appropriate, more responsive to patients‟ needs

and more efficient. In Wales this includes the Delivering Emergency Care Strategy that was

announced in February 2008

A key theme in these initiatives is the recognition that the current system of providing

unscheduled care is inefficient and in many cases does not meet the patient‟s needs in the

most effective way. In particular, they recognise that addressing the patient‟s needs in a

timely and appropriate manner whilst at the same time preventing unnecessary admissions

to hospital should be a high priority for a well managed unscheduled care system. In this

context they also recognise that appropriate assessment and triage of the patient‟s needs at

the point at which the patient accesses the healthcare system is key to the delivery of the

most appropriate service and the best outcome for the patient.

In recognition of this fact, there has been a significant change in the past three to four years

in the way in which ambulance trusts in England respond to 999 emergency calls. At the

core of this is the recognition of the need for a separation between the response to the initial

emergency and the assessment of the patient‟s needs from the subsequent process of

transporting the patient to hospital once it has been determined that this is the most

appropriate response. This has led to an increase in the number of cases where a single

staffed response car staffed by a paramedic attends an incident prior to a decision to deploy

an ambulance. There has also been an upskilling in the capabilities of the staff employed by

ambulance trusts to enable them to assess the needs of the patient and - where appropriate

- to treat the patient at home or at the scene of the incident. As a result, in trusts that have

adopted this model of response there has been a significant reduction in the proportion of

patients who are transported to hospital with rates of transportation to hospital now below

55% in some cases by comparison with the 72% transportation rate that is seen in Wales.

In parallel with the trend to place more reliance on the use of single responders for the initial

assessment of the patient‟s needs, the English ambulance trusts are also required to meet a

significantly higher standard of initial response to life threatening Category A incidents than

currently applies in Wales. The response standard that applies to the English trusts is to

attend 75% of all Category A incidents within 8 minutes from the time that the caller is

connected to the trust‟s switchboard. This compares with the AOF target that applies in

Page 12: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

12

Wales which requires that WAST responds to 65% of Category A incidents within 8 minutes

from the time that the calltaker has determined the nature of the emergency. The effect of

this is that the response time in relation to Category A incidents in Wales is around 80

seconds longer than it is in England as shown in Figure 1 below. It should be noted

however, that the move to the new „Call Connect‟ performance standard in England has

required significant investment in both resources and technology and took over two years to

achieve. The benefits that the English trusts have obtained from this investment in terms of

their ability to respond quickly to incoming calls also makes it difficult to undertake a direct

comparisons of their performance with WAST.

Figure 1 – The Category A 8 minute response standards

The overall effect of these changes has been that English trusts are now placing a

significantly greater reliance on single staffed vehicles to provide the initial response to

Category A calls and are also experiencing an increasing number of cases where a single

staffed vehicle is the only response that is required for Category B and Category C incidents.

By contrast in Wales double staffed ambulances still constitute the initial response for 70%

of all 999 calls. The issues associated with the greater use of single staffed response

vehicles are discussed in more detail below.

3.2. Establishing equitable and appropriate standards of response

across the community

A key consideration when determining the most appropriate way for an ambulance service

to meet its performance targets is the need to establish equitable standards of response

across the whole community whilst at the same time recognising the implications of the

standards that are agreed in terms of both practicability and cost effectiveness.

The overarching consideration in determining the achievability of the performance targets is

the way in which geography, demography, transport, road and health infrastructures

influence the amount of resource that is required to achieve the target in question. This is

Page 13: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

13

materially different when considering the response to the Category A 8 minute target and the

Category A and Category B 14/18/21 minute standard.

3.2.1. The Category A 8 minute response process

The primary purpose of the Category A 8 minute target is to provide lifesaving services to a

patient who has suffered a heart attack within a timeframe that carries a reasonable chance

of resuscitation. In this context the response can consist of any suitably trained person who

has access to a defibrillator which they have been trained to use and does not have to

consist of a vehicle capable of transporting the patient. (The provision of suitable

transportation for a Category A incident is is covered by the 14/18/21 minute standard).

In order to meet this standard, a trust has to plan with a high level of certainty to have a

suitable level of response resource available that is capable of attending these life

threatening incidents within the time that is allowed for the response. The amount of

resource that is required to deliver this standard of response is determined by the likely

location of the incident and the amount of time that the responder has available to travel to

the incident.

The time that is available for the responder to travel to the scene of the incident is the time

that remains within the 8 minute response window once

the response vehicle has been identified by the dispatch centre

the responder has been notified of the incident and

the responder is in the response vehicle and beginning to travel to the scene of the

incident.

In the case of WAST, the time that is available for the responder to travel to the scene of the

incident - assuming best practice processes and technology - is 7 minutes as summarised

in Figure 2 below

Figure 2 – The components of the Category A response process

Page 14: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

14

The implication of this is that it is only possible to reach a Category A incident within the 8

minute window where there is a response resource that is already available and positioned

within a 7 minute drive time of the incident at the time that the 999 call is received.

Consequently in determining the amount of resource that is required to meet the standard it

is necessary to identify the locations where Category A incidents are most likely to occur and

to plan the deployment of the Trust‟s response resource within those areas.

3.2.2. Response areas and achievable response standards

A typical area that could be covered within a 7 minute drive time is shown in Figure 3 below

Figure 3 – A 7 minute deployment area in Caerphilly

By identifying those areas where Category A incidents are most likely to occur it is then

possible to identify the optimal location of response vehicles within 7 minute „drivezones‟ to

maximise the likelihood that the incident will receive a response within the 8 minute

response window. Deployment planning of this type has played a very significant role in

enabling English trusts to meet the new Call Connect standard. A similar approach is already

utilised by WAST in North Wales and is under development within the South East and

Central and West regions. It should be noted however that WAST‟s current technology

systems do not support a technological solution similar to that which is used by the English

ambulance trusts and they are therefore using paper based systems to support this

approach to deployment.

Where adequate resource is available and it is deployed in this way, a high level of Category

A performance is often achieved – in some cases in excess of 85%. However, it is clear that

this approach to deployment, which requires the provision of a dedicated response resource

which is fully funded by the ambulance trust, will only be cost effective in those more densely

populated areas where there is a sufficiently high level of activity to ensure that the response

vehicle undertakes a reasonable level of activity.

Page 15: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

15

Typically urban area activity of this type, where there is a high probablility of 2 or more

category A incidents occurring in any 24 hour period within a „drivezone‟, accounts for

between 70% and 80% of the activity within the area of an ambulance trust. This leaves

between 20% and 30% of the Category A incidents where an alternative model is required

for the provision of initial response.

The areas outside the more densely populated urban areas fall into three groupings as

follows

Mid sized market towns where there is a predictable level of daily activity, but there

are less than 2 Category A incidents on average per day

Smaller towns and large village communities where there is occasional activity but

there is less than 1 Category A incident on average per day and

Sparsely populated rural areas where activity is widely spread and there are no

material concentrations of population

In the mid sized market towns, it is not realistic or cost effective for the ambulance trust to

provide a dedicated resource solely to respond to Category A incidents within the 8 minute

response window. However, it is possible for the ambulance trust to establish a retained

(paid for) response scheme in collaboration with the local health community and possibly

also involving the Fire and Rescue Service and the Police which can provide an appropriate

level of initial response for that community. In these cases it is realistic to expect that an

initial response provided by a scheme of this type will meet or exceed the 65% Category A

standard.

In the smaller towns and larger villages, it is more difficult for an ambulance trust to provide

an assurance of a suitable level of initial response without the involvement of volunteer

responders. In many parts of the United Kingdom there are a large number of communities

of this type which are more than a 7 minute drive from the nearest town and where typically

there will be at most one or two Category A incidents per week. The only practical way of

providing an initial response in these areas within the 8 minute window is through a voluntary

Community Responder scheme. Where such schemes exist they can provide a high level of

initial response to their local community, but the development of schemes of this type is time

consuming and requires a high level of commitment from the local community. It should be

recognised, however, that although the community responders are volunteers, the

infrastructure necessary to support, manage and deploy community responders has its own

cost that has to be borne by the ambulance trust.

In the sparsely populated areas, which are outside the reach of a community response

scheme, it is unrealistic for an ambulance trust to plan to achieve any sustained level of

category A 8 minute performance and in general ambulance trusts find it difficult to achieve

levels of Category A performance above 40 - 50% outside the urban areas and the larger

market towns.

3.2.3. The Category A and Category B 14/18/21 minute response

standard

The 14/18/21 minute Category A and Category B standards in Wales require that a fully

equipped ambulance attends the incident within the specified time window measured from

the start time of the incident. This corresponds to similar 19 minute standard that applies to

ambulance trusts in England.

This standard exists in order to address three separate requirements as follows

In the case of a Category A incident where the initial response has been by a

community responder or another responder that is not provided directly by the

ambulance trust the standard ensures that this lay response is backed up within an

appropriate time by a suitably trained responder provided by the ambulance trust

In the case of a Category B incident the standard ensures that there is an appropriate

initial response to the incident by a suitably trained responder provided by the

ambulance trust

In the situation where it is determined that the patient requires urgent transportation

to hospital the standard ensures that a suitable transportation resource will be made

available within an appropriate time.

It is however particularly important for the efficiency and effectiveness of the ambulance

service that the performance standards for the initial response and for the subsequent

transportation of the patient are addressed separately. Indeed, if this distinction is not

recognised within the performance standard, it will not be possible to obtain the benefits that

would otherwise be available from the more extensive use of single staffed response

vehicles to undertake the initial assessment of the patient‟s requirements.

The reason for this is that in those cases where it is appropriate to send a single staffed

vehicle to an incident it will take a minimum of 10 minutes from the start of the incident

before it is clear whether transportation is required. In most cases this leaves insufficient

time for a double staffed ambulance to travel to the scene within the available time window

should this be required. Moreover in many cases where transportation to hospital is required

it will not be necessary for this to be provided immediately in a fully equipped emergency

ambulance.

However, if the performance standards are interpreted to apply to both the initial response

and also to the arrival of the transportation resource it is necessary to send a double staffed

ambulance to every Category A and Category B incident whether or not a single staffed

response car has also been dispatched to respond to the incident. This has two effects.

Firstly it significantly reduces the potential benefits of any investment in single staffed

response vehicles in terms of their potential to reduce the ambulance attendance and

transportation rates. Secondly it requires the Trust to maintain a level of resource in the form

of double staffed emergency ambulances which is higher than it would otherwise need to be.

As a result, it is increasingly being recognised that a more appropriate approach is to

establish separate performance standards for the initial response to incidents and for the

Page 17: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

17

subsequent transport requirement. This means that the standard for the initial response

relates to the attendance by a fully equipped response vehicle. A second standard can then

be established for emergency transportation which requires that where an urgent request

has been received for transport by an emergency ambulance, the transporting vehicle

arrives at the scene within the appropriate time window measured from the time at which the

request for transportation is received.

The current position with respect to the appropriate interpretation of the 14/18/21 minute

response standards in Wales is unclear. The standards which were drafted in 1999 are

clearly response standards rather than transportation standards. However, the standards

predated the wider use of single staffed response vehicles and therefore refer to the

response provided by WAST taking the form of a fully equipped ambulance rather than a

fully equipped response vehicle as is the case in England. As a result it is open to

interpretation whether a single staffed response vehicle is a suitable initial response to meet

the 14/18/21 minute standard for both Category A and Category B incidents and at the time

of our review this issue remained unresolved.

3.2.4. The 14/18/21 minute response process

Unlike the case with the Category A 8 minute target it is possible to develop a deployment

strategy that will ensure that all of the regions within Wales have a response by a fully

equipped emergency vehicle within the 14/18/21 minute standard. In order to be able to

meet this standard, however, WAST requires sufficient transportation resource to be able to

respond not only to the normal daily levels of activity, but also to peak levels of activity and

to provide the required level of cover and transporting capacity across all the geographic

regions in Wales. The factors that determine the amount of resource that is required to meet

this standard are

The predicted average and peak level of activity at each hour for each day of the

week

The volume of activity and the geographic area that can be covered by an ambulance

operating in more rural areas

The percentage of incidents that require transportation to hospital

The length of time that it takes an ambulance to complete a job, including in

particular

o the time taken to reach the hospital

o the time taken to return from hospital and

o the time taken to hand over the patient to the care of the hospital staff.

In calculating this resource requirement it is also important to recognise that the same

double staffed ambulance resource is also required to meet the performance standards for

Urgent incidents as well as responding to Category C incidents and Hospital Transfers. In

Page 18: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

18

this context, ambulance trusts are examining options for providing transport to hospital in

cases where the patient‟s condition does not require them to be accompanied by a

paramedic or in a double staffed vehicle. This includes the more extensive use of an

intermediate tier of high dependency vehicles that can be staffed by two intermediate staff or

the use of patient transport service vehicles in the same way as is provided for patients who

are attending hospital for planned appointments.

3.3. Emerging clinical best practice

Ambulance services are increasingly recognising that in order to meet patients‟ clinical

needs in the most appropriate way they need to reconsider all aspects of their activities. This

extends from the initial way that calls are triaged through to the range of alternative

treatments that can be offered to the patient at the patient‟s home as well as the alternatives

that exist to hospitalisation.

At the level of callhandling, there are significant differences between ambulance trusts in the

way that calls are classified by call takers. There are a number of factors that affect the rate

of classification which make benchmarking of this measure difficult. In WAST at the time of

our review Category A call classification was around 40%. In other trusts it ranges from as

high as 45% to below 30%. One key consideration that influences the percentage of calls

that are classified as Category A is the calltaker‟s knowledge of the call triage system and in

particular the extent to which supplementary questions are used to clarify the nature of the

incident. We understand that WAST has been working hard recently to ensure that calltakers

are trained in the use of the supplementary questions and that the proportion of calls

classified as Category A had fallen to 37% in the course of June 2009.

In trusts with the lower rates of Category A calls, effective use of the supplementary

questions is often combined with a clinical desk where a caller may be passed from the

calltaker to a nurse or paramedic who continues to talk to the patient whilst at the same time

a vehicle is travelling to the incident. This may result in the incident being downgraded to a

lower categorisation. In the case of Category C incidents in particular this also provides

opportunities for rerouting patients to alternatives to an ambulance. This may be NHS Direct

or an Out of Hours service or may result in the patient attending a minor injuries unit without

the need for an ambulance. An appropriately resourced clinical desk also allows paramedics

who are on scene to discuss suitable treatments with a colleague and provides information

about the alternatives that are available. We understand that WAST has already trialled the

use of clinical nurse advisers to triage Category C emergency calls by telephone and is keen

to extend the use of this service.

A further development which WAST is also discussing is the provision of an information hub.

This can involve a bed bureau function that maintains a central information source that can

identify where there are available beds for patients. It can also be a source of information

about the available resources to meet patients‟ needs including information about services

provided by social services and voluntary services as an alternative to taking the patient to

hospital. This can also provide a more integrated link between the ambulance service, NHS

Page 19: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

19

Direct and Out of Hours services – something that WAST is particularly well placed to do

because both the EMS service and NHS Direct Wales are now within a single trust. In this

context we understand that WAST has submitted an expression of interest in accordance

with the Assembly‟s Invest to Save initiative to implement NHS Pathways jointly with health

and Social Care partners in Wales.

In addition, WAST already has a relatively high proportion of its front line staff who are

paramedics which provides a good starting point for the transition to the alternative response

model. However there will be a requirement for a change in working practices from the

current position where the majority of paramedics work primarily on double staffed

ambulances and are currently accustomed to receiving backup in almost all cases when they

are working on single staffed response vehicles. The future model will put significantly

greater emphasis on paramedics being able to work alone in the first instance and spending

a larger proportion of their time in single staffed response vehicles. An additional issue that

will need to be addressed is the number of incidents that are attended by a single staffed

vehicle. The new model will require paramedics to act as first responders in areas where

activity is relatively low. In some cases - notably in towns where the expected level of activity

is less than two Category A calls per day - it may be more appropriate for these staff to

become part of a community medical team and to provide support for admissions avoidance

and long term conditions management rather than requiring them to act solely as a response

resource to 999 calls.

In this context, it will also be appropriate for WAST to consider more extensive use of

Specialist Practitioners. Different trusts have developed different practices towards the use

of schemes of this type and in a number of cases these schemes have proved to be very

effective in treating the patient at home or providing support for minor injury units and so

helping to reduce the number of cases where Category B and Category C incidents require

ambulance attendance or transportation. The introduction of Specialist Practitioners is part of

WAST‟s five year workforce plan and we understand that recruitment is currently under way

to fill these roles.

A further possibility in terms of the development of clinical services that can be provided by

ambulance trusts is demonstrated by the fact that some ambulance trusts in England have

begun to set up and operate minor injury units themselves as part of an admissions

avoidance strategy.

Clearly developments of the type outlined above cannot be achieved without careful

planning. But they are indicative of the changes that are under way within the ambulance

service and they will lead to ambulance trusts which are very different organisations from

what they have been in the past. This requires them to be more closely integrated in to the

unscheduled care system with a different range of clinical capabilities and skills and with a

very different leadership from the traditional ambulance service. This is fully recognised by

WAST and the trust is working hard with its partners in health and social care to achieve

these outcomes.

20

3.4. The impact of technology

The ability of an ambulance service to deliver a high quality service to patients in its area is

critically influenced by the technology that the trust has at its disposal. There are a number

of key components to this technology which affect the ability of the trust to operate at the

highest levels of performance. These are

Computer aided dispatch (CAD) systems which manage the deployment of vehicles

and their dispatch to individual incidents

Automatic vehicle location systems (AVLS) which are able to identify at all times the

exact location of vehicles and to provide this information to the CAD system. This

enables the CAD to track vehicles throughout the day to optimise the way in which

vehicles are deployed and dispatched to incidents and to calculate the exact times

that are taken by vehicles to mobilise and travel to the scene of an incident

Mobile data systems that allow the dispatch centre to communicate automatically

with response vehicles and which provide sat nav guidance to the crew to find the

quickest route to the incident

Automated caller line identification systems which speed up the process of identifying

the location of an incident by showing the calltaker the address of a landline from

which a call is being made

An electronic patient record system in the form of a handheld device that can be

used by ambulance crews to speed up the recording of the details of an incident and

provide an electronic record of these details for subsequent use

Historically WAST‟s technology infrastructure has been a significant hindrance to its ability to

perform at a level comparable with other ambulance trusts. In particular the absence of a

suitable radio system in Wales prevented the introduction of AVLS with the result that it was

only possible to identify where a vehicle was by contacting the crew by phone and asking

them to confirm their location. WAST estimate that the absence of AVLS has resulted in a

level of Category A performance that is 5 percentage points below where it would otherwise

have been. We understand that the business case for mobile data and AVLS has now been

approved and these benefits are likely to be introduced during 2009-2010.

The majority of ambulance trusts in England either have introduced or are currently planning

to introduce the current generation of CAD systems and it is on these systems that CAD

providers are currently focusing their development efforts. WAST currently operates with a

legacy CAD system that has been superseded by a more up to date system from the CAD

provider. As a result, although the system will be maintained, it will not benefit from the

enhancements that will be applied to the later system and over time the performance of the

current system will lag behind. Consequently the system will have to be upgraded or

replaced in the near future if WAST is to maintain a level of performance that is comparable

with other Trusts. We understand that WAST is currently developing a plan to replace the

current CAD system during 2009/10.

Page 21: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

21

The limitations of the current CAD and the lack of a mobile data system also means that

WAST cannot obtain the full benefits of an automated caller line identification system.

Although as shown in Figure 1, the current performance standard does not include the time

taken to answer the call and identify the location of the incident, nevertheless the absence of

this technology is delaying the response to the patient and will become a key requirement if

WAG were to decide to change the performance standards to start from the time that the call

is answered.

3.5. Implications of the model

There are significant benefits in terms of efficiency and effectiveness for WAST to move in

the direction outlined in this Section. These include

Impoved patient experience

More effective and efficient use of operational resources

Leverage on the investment that has already been undertaken

Better and more fulfilling roles for staff both in front line and support roles

Greater integration with the rest of the NHS in Wales in the delivery of urgent care

In many ways WAST is well placed to move in this direction. It is the only organisation within

the NHS in Wales that has an overview on a day to day basis of the pattern of demand for

unscheduled care. In addition, WAST has the considerable advantage relative to ambulance

trusts in England of already having completed a merger with NHS Direct Wales and it also

provides the support for the Out of Hours in part of the region. Furthermore it already has a

relatively high proportion of its staff who are paramedics.

However it would also pose significant challenges and would require change in organisation

and practices. In particular it would require

Willingness of staff and the public to accept the change to single staffed response

Further upskilling of staff in control

Further upskilling of clinical staff

Further upskilling of financial/support staff

Investment in appropriate technology to support the change

The rest of this report assesses the current position of the Trust in relation to its existing

mandate, its current performance effectiveness and its readiness to move in this direction.

4. Findings

4.1. Benchmarking

Appendix 1 sets out a proposed set of benchmarking data which – if it were collected for

different ambulance trusts - would allow a full comparison to be made of the effectiveness

and efficiency of WAST in comparison with other ambulance services. Currently a subset of

this data is available from different trusts and based on the available data we have prepared

the following comparisons between WAST and two high performing English trusts with a

similar geographical pattern of activity to that seen in Wales – South Western Ambulance

Service and East of England Ambulance Service

Table 1 – Selected Benchmarking data

Page 23: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

23

The main conclusions from these figures are as follows:

999 calls per head of population – WAST receives one call per year for every 6.2

people in Wales by comparison with one call per 6.5 people in the case of South

Western Ambulance Service and one call per 9.9 people in the case of East of

England Ambulance Service

Page 24: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

24

Average income per call received – WAST receives 9% less income per call received

than South Western Ambulance Service and 22% less than East of England

Ambulance Service. WAST receives 8% more EMS calls than South Western

Ambulance Service but 14% fewer calls than East of England Ambulance Service.

Dividing the EMS income by the number of calls gives the following figures.

o WAST - £195 per call

o South Western Ambulance Service - £209 per call

o East of England Ambulance Service - £250 per call

Average income per head of population – WAST receives 6% less income per head

of population in EMS funding than South Western Ambulance Service and 24% more

per head of population than East of England Ambulance Service. Dividing the EMS

income by the population headcount gives the following figures

o WAST - £31.35 per head of population

o South Western Ambulance Service - £32.88 per head of population

o East of England Ambulance Service - £25.24 per head of population

Headcount – WAST has a whole time equivalent headcount that is 11% more than

South Western Ambulance Service total headcount and that is 30% less than East of

England Ambulance Service. However for frontline services WAST has a headcount

that is 6% lower than South Western Ambulance Service and 39% lower than East of

England Ambulance Service.

EMS Vehicles – WAST has 5% more EMS vehicles than South Western Ambulance

Service and 29% fewer vehicles than East of England Ambulance Service.

Area covered – with an area of 20,640 Square KM in which to operate WAST covers

15% more area than South Western Ambulance Service and 6% more than East of

England Ambulance Service.

The comparisons above demonstrate the difficulty of basing a comparison of the efficiency of

an ambulance trust on any one benchmarking measure. Under the measure of funding per

999 call, WAST received a lower level of funding than either South Western Ambulance

Service or East of England Ambulance Service in 2007/8. However, under the measure of

funding per head of population WAST received a lower level of funding than South Western

Ambulance Service but a higher level of funding than East of England Ambulance Service. It

is therefore necessary to consider a range of complementary measures in order to gain a full

understanding of the external factors that affect the ambulance service as well as the

efficiency with which the service is operated

Table 2 below provides a further ranking for the three trusts using certain publicly available

indicators.

Page 25: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

25

Table 2. Comparison of WAST with benchmark trusts on selected benchmark metrics

As can be seen from the rankings above the indicator where WAST scores highest is the

number of incidents responded to per member of front line staff and the measurement of

income per member of frontline staff. This reflects the fact that WAST is currently operating

with high levels of overtime and low levels of relief thereby running the service with fewer

frontline staff than would be recommended.

Table 3 compares WAST‟s performance in relation to key call cycle measures with the

performance of an area within the East of England Ambulance Trust consisting of Essex,

Norfolk, Suffolk and Cambridgeshire – a geographic area that is highly comparable with

Wales in terms of the proportion of activity that occurs in sparsely populated areas.

Page 26: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

26

Table 3 – WAST call cycle performance against East of England benchmark area

This underlines that the key difference in the management of the call cycle between WAST

and East of England Ambulance Service lies in the initial phase of call handling, the

allocation of a vehicle to an incident and the time it takes for the vehicle to arrive at the

scene of the incident. This reflects the availability of resources, the investment in technology

that is available to support the call handling and dispatch processes and the effectiveness

with which the deployment plan and other Control room processes are managed. WAST

compares well with East of England Ambulance Service with respect to the remainder of the

call cycle once a vehicle has arrived at the scene of the incident. The table also highlights

the fact that in trusts such as East of England Ambulance Service which have lower hospital

transportation ratios the amount of time spent at the scene of the incident by the attending

vehicle increases.

4.2. Achieving the Category A 8 minute AOF target

Our analysis of the distribution of Category A activity within Wales has confirmed that, with

the appropriate resource and infrastructure, it is possible for WAST to meet and even to

exceed the current 65% target by adopting a structured approach to response based on the

principles of separating initial response from transportation.

Our analysis is based on the following assumptions

WAST will provide a dedicated response resource to respond to at least 75% of

Category A incidents within 8 minutes in any area („Urban areas) where there are 4

Page 27: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

27

or more Category A and Category B incidents per day within a 7 minute drivezone

area

WAST will ensure that there is a suitable response resource available to respond to

at least 70% of all Category A incidents within 8 minutes in any area („semi urban‟

areas) where there are between 2 and 4 Category A and Category B incidents per

day within a 7 minute drivezone area. This may be a dedicated trust resource or may

be a response scheme developed jointly with the local health community

WAST will seek to develop appropriate community response schemes in other areas

(„rural‟ areas) where there are less than 2 Category A and Category B incidents per

day within any 7 minute drivezone area. Category A performance in these areas is

currently 40%, and WAST should aspire to raise performance in these areas to 50%

by developing additional schemes

WAST has fully deployed AVLS and mobile data

The urban and semi urban areas we have identified in each of the LHB areas where we

recommend that WAST should locate its deployment points for its vehicles are listed in

Appendix 2.

Based on these assumptions, the levels of activity in these three areas in each of the LHB

areas and the possible levels of performance in each of the LHB areas and across WAST is

as follows

Table 4 –Category A activity and potential performance by LHB area

This shows that Wales does not have an unusually large proportion of its activity in rural

areas by comparison with English trusts of comparable size. Moreover, with the exception of

Powys, no LHB area has a level of rural activity which is out of line with similar geographical

areas in England which already achieve Category A performance at levels which are at least

as good and in many cases higher than the performance levels indicated in Table 4.

Page 28: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

28

Consequently it should be possible for WAST to achieve the levels of performance indicated

with a suitably resourced response model of this type.

In order to achieve these levels of performance, however, WAST will have to place greater

emphasis on the use of single staffed response vehicles which are the key resource that is

required in order to achieve a reliable and consistent level of Category A performance with at

least 50% of all Category A calls in the urban areas being attended in the first instance by a

single staffed response vehicle. In addition, focused attention is required to ensure that there

is an appropriate initial response resource – either in the form of a double staffed ambulance

on a standby point or an appropriately funded first responder scheme – in all the semi urban

areas that have been identified.

In addition to these initiatives, WAST also needs to increase the use of Community

Responder schemes and on-site static defibrillators at locations where Category A incidents

are likely to occur. The existence of schemes of this type are an important contributory factor

to the overall level of the initial response to Category A incidents, particularly in rural areas.

In a number of English ambulance trusts initial response of this type contributes up to ten

percentage points of the overall Category A 8 minute performance. By contrast in Wales this

type of response currently contributes only around five percentage points to overall category

A performance, with Community Response schemes contributing less than two percentage

points to overall Category A performance in the first quarter of 2009. We understand that

WAST plans to appoint a National First Responder manager with the objective of

significantly improving the contribution from these types of scheme.

4.3. The implications of extended travel times and hospital delays

The length of time for which an ambulance is committed to any incident before it is available

to attend a subsequent incident is a key factor in determining the amount of resource that an

ambulance trust requires. Where ambulances are committed to incidents for longer than

expected this has a significant impact on the ability of an ambulance trust to meet its

performance targets. The two factors that have the greatest influence on the variability of

the job cycle time for an ambulance are extended travel times to hospital and delayed

handovers at hospital.

In ambulance services which achieve relatively high levels of utilisation of their ambulance

resource, the average time for which an ambulance is committed to an incident in a highly

populated urban area with a local hospital in the vicinity is around 62 minutes as

summarised in Figure 4 below

Page 29: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

29

Figure 4 – The best practice ambulance call cycle in urban areas

This incident cycle time enables an ambulance trust to plan on the basis that an ambulance

will complete its involvement in any incident in one hour (this is referred to as one „unit

hour‟). However, when the time taken to travel to the hospital or to hand over the patient is

extended, the „unit hour‟ has to be increased to take into account this additional time. In the

case of an extended travel time to hospital, the effect on the incident cycle time is further

compounded by the fact that the vehicle in question has to travel a longer distance both on

the inward journey to the hospital and on the return journey. This can have a significant

effect on the availability of ambulances and consequently the number of vehicles that are

required to respond to a given level of activity.

In the same way, when the handover of the patient at the hospital takes longer than 15

minutes, this also has an effect on the amount of resource that the trust needs as the vehicle

is unavailable to attend a subsequent incident

The overall impact of extended travel times and hospital delays is shown in Table 5 below

which indicates that additional resource is required to compensate for these effects in each

of the new LHB areas.

Table 5 – Extended travel times and hospital handover times by LHB area

4.4. Calculating resource requirements for WAST

4.4.1. Unit hour requirements

In order to meet the Category A 8 minute AOF target, as well as preparing for the change

towards the response model outlined in Section 3.2 above, WAST needs to be able to

provide sufficient single staffed response vehicles to respond to a minimum of 50% of the

anticipated Category A incidents in all the urban areas identified. In addition, in order to meet

the 14/18/21 minute standards, WAST also has to plan to have sufficient double staffed

ambulances to attend all the Category A and Category B incidents that may require an

ambulance to transport the patient to hospital as well as having sufficient ambulances to

respond to Category C, Doctors Urgent and Hospital Transfers incidents in a timely fashion.

As outlined in Section 3.2.3 above, the interpretation of the Category A and Category B

14/18/21 minutes standards has a significant effect on our findings. At present WAST is

interpreting these standards on the basis that a double staffed ambulance is required to

attend a Category A or a Category B incident within the 14/18/21 minute time window in 95%

of cases where an ambulance arrives on scene. As a result, WAST is currently sending

ambulances to a high proportion of all 999 incidents even where a single staffed response

vehicle has also been sent to the incident. Moreover, since it is not clear at the start of an

incident whether an ambulance will be required, the only way in which the standard could be

met consistently and reliably would be to send an ambulance immediately to every incident

where a vehicle attends. This requires WAST to increase still further the number of

ambulances that are sent to incidents

Based on this interpretation of the 14/18/21 minute standard (the „Base case‟ scenario),

Table 3 sets out our estimate of the average number of rapid response vehicle („ RRV‟) and

ambulance hours that WAST would require per week to meet all the performance targets

and standards in each LHB area in 2009/10. This shows that WAST would require an

additional 1100 RRV hours per week together with a further 1118 ambulance unit hours by

comparison with the current planned rotas to deliver the 14/18/21 minute standards as well

as the AOF targets.

Table 6 – Unit hours required - Base case scenario

Page 31: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

31

If this interpretation of the 14/18/21 minute performance standards is used, any additional

investment in RRVs would be extremely inefficient as RRVs would be accompanied by

ambulances to all incidents whether or not the ambulance was required as a transport

resource. This would preclude WAST from gaining the potential benefit of the reduction in

ambulance unit hours that would otherwise be available from the more effective use of single

staffed response vehicles. Moreover, the current operating procedures in WAST result in a

significantly higher proportion of ambulances attending 999 incidents than occurs in

comparable English trusts and also results in a materially higher proportion of patients being

transported to hospital. As Table 4 shows, WAST‟s overall ambulance attendance ratio for

999 calls would be 93% if double staffed ambulances were required to meet the 14/18/21

minute standard in all cases. This compares with 81% achieved in the East of England

Ambulance Service. Similarly, the ambulance transportation ratio in Wales in Q1 2009 was

70% by comparison with 52% in East of England Ambulance Service. This results in WAST

utilising 1745 more ambulance hours per week and transporting 1108 more patients per

week to hospital than would be the case at the East of England Ambulance Service. .

Table 7– Ambulance attendance and transportation ratios

By contrast, if the alternative interpretation of the 14/18/21 minute response standards were

used which would allow the increased use of single staffed response vehicles to undertake

an initial assessment of patients as is the case in England, 410 fewer ambulance hours

would be required to meet the performance standards by comparison with the current rotas

and in addition there could be a significantly different outcome for patients by avoiding

unnecessary attendances at hospital. At the same time, however, there would also be an

increase in the time that was spent at the scene of the incident assessing the patient‟s needs

which would have to be taken into consideration in determining the overall adjustment to the

required resource

In should also be noted that the total recommended unit hours for ambulances in Table 6

includes an adjustment of 900 hours per week to reflect the effect of extended hospital

turnaround time as set out in Table 2. If the pattern of extended hospital delays that has

been observed over the past year could be addressed, this would result in a further

reduction in the amount of ambulance resource that WAST requires. However, it should also

Page 32: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

32

be noted that any change in operating practice towards a greater reliance on single staffed

response vehicles as the initial response to incidents will involve significant changes in

working practices and will require careful planning by WAST. It would also require the

availability of alternative pathways for patients who would otherwise be taken to hospital.

4.4.2. Ambulance staff requirement

The staff resources required to fill the recommended rotas and the associated cost is

dependent on a number of factors

The number of hours that are assumed to be available per week once factors

such as sickness, holidays, training time and other anticipated non availability

(collectively referred to as „Relief‟) has been taken into account

The amount of overtime that is required to cover shift overruns and other

unanticipated hours worked („Core overtime‟)

The amount of overtime that is assumed to be worked in addition to contracted

hours to fill planned shifts („Additional overtime‟)

The additional payments that are required over and above base salary to cover

items such as unsocial hours and pension contributions („Add on costs‟)

The proportion of staff of different levels of qualification that are required to cover

shifts on different types of vehicle

The position with respect to the availability and use of front line ambulance resource in

WAST in 2008/9 is set out in Table 5 below

Table 8 – Front line staff resource, cost and available hours to fill rotas

This shows that in 2008/9 WAST had a total of 1301 front line staff with a total direct cost of

£53.6mn and an overtime rate of around 19%. Based on the 2008/9 overtime rates and the

assumption of a relief factor of 26.8% this would have produced a total of 42,522 hours

Page 33: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

33

available to man vehicles which matches almost exactly the total of 42,502 rota hours that

were planned by WAST.

4.4.3. Adjusting for overtime and relief

The implications of this increase for the additional number of staff that WAST would require

and the associated cost of those staff depends critically on the assumptions that are made

for 2009/10 about the rate of additional overtime that it is acceptable to plan for and also the

appropriate level of relief that WAST should build into its planning.

4.4.3.1. Overtime

In our calculations, we have assumed that the amount of overtime that WAST requires to

cover shift overruns and other unanticipated extractions is 5%. This compares with an actual

rate of payment for shift overruns in 2008/9 of 4%. Based on this planning assumption the

level of additional overtime (ie overtime paid to fill core shifts) was particularly high in 2008/9

at around 14%. This is a relatively inexpensive way for WAST to increase the available

hours to fill its shifts, but it depends on the willingness of staff to work additional hours and

as such does not provide a robust mechanism for managing rosters. It also raises issues

about the extent to which a planned reliance on overtime is an appropriate HR policy. It

would therefore be imprudent for WAST to plan to continue to rely on these levels of

overtime in 2009/10 as a means of filling core rota lines.

The actual figure for additional overtime in any year will be dependent on the extent to which

vacancies are filled and other extractions are in line with plan. Our calculations of the

resource requirements that are required to meet the existing performance standards

therefore show the resource requirement under two different scenarios – a current scenario

where WAST continues to operate with the levels of overtime employed in 2009/10 and an

alternative calculation where overtime is used solely to cover unplanned extra hours at the

end of shifts or to cover occasional unanticipated peaks in sickness etc.

4.4.3.2. Relief

The level of relief that WAST builds into its plans is also a critical factor affecting staff

numbers and costs. A level of relief has to be built in to resource planning to cover factors

such as holidays, sickness, training and other planned and unplanned absence. The main

components of relief are

Annual Leave

Public holidays and time off in lieu

Sickness

Training

Maternity leave

Other (including staff management duties, internal meetings, union representation

etc)

Page 34: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

34

It is generally recognised that best practice staff management in ambulance trusts would

apply a relief factor of 35% to cover these factors - a level recommended in a Department of

Health paper released in April 2007.

In practice, there is considerable variation in the relief factors that ambulance trusts apply in

their resource planning. For example, whilst WAST plans at 26.8% in the case of the

services used for comparative purposes the South Western Ambulance Service uses a 35%

relief planning assumption, whilst the East of England Ambulance Service plans at a level of

28% . However, since most of the other factors resulting in staff being unavailable for work

such as holidays and sickness are non discretionary and the resulting absence has to be

covered from the relief factor, it is typically the ongoing training component which suffers

when trusts are unable to operate at a sufficiently high level of relief and this is currently the

case in WAST based on the current relief factor of 26.8%. It is therefore highly desirable

from a staff management perspective that WAST should increase its relief factor from its

current low rate as soon as it is able in order to be able to plan for appropriate ongoing

professional training for staff.

The precise level of relief that WAST needs to incorporate into its planning depends on the

detailed training requirements of its staff. We have not undertaken an analysis of the training

days that WAST needs to set aside to ensure that its staff maintain the appropriate levels of

ongoing training and we have therefore undertaken our analysis of the resource implications

of adjusting the relief factor based on the 35% rate that is included in the Department of

Health publication.

4.5. Achievable performance levels and additional resource

requirements under different scenarios.

4.5.1. Achievable performance levels with existing resources

As Table 9 shows, if WAST continued to operate with its current levels of staff and current

overtime and relief factors, but was also able to match the best practice call cycle

management processes that are operational in the high performing English trusts, we

believe that it would be possible for WAST to meet the 65% Category A 8 minute AOF target

in 2009/10 and to meet the 60% standard in each of the LHB areas under each of the

following three scenarios.

1 Hospital delays continue at the level observed during the reference period for this

study

2 70% of hospital handovers are achieved within 15 minutes

3 90% of hospital handovers are achieved within 15 minutes.

Page 35: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

35

Table 9 – Achievable performance levels with current establishment

However, Table 9 also confirms that - based on the current operating model - WAST would

not be able to meet either the Category A or Category B 14/18/21 minutes standards or the

standard for Urgent journeys under any of these three scenarios based on the current

operating model. In addition, if WAST were to operate with a lower level of overtime and a

higher relief factor it would only be able to meet the Category A 8 minute performance

targets if hospital delays were reduced significantly below the levels observed during our

review.

4.5.2. Additional resource requirements to meet the 14/18/21

minute performance standards

Based on the analysis outlined in Section 4.4 above, we have analysed the additional staff

requirement and the associated costs for WAST under the following scenarios with respect

to the 14/18/21 minute standards

1 WAST sends a double staffed ambulance to all Category A and Category B incidents

which requires a vehicle to attend (The „Base Case‟ scenario)

2 WAST continues to send double staffed ambulances to the majority of Category A

and Category B incidents as at present (the „Current response‟ scenario)

3 WAST reduces its ambulance attendance at all categories of incidents to the best

standards achieved by English trusts (the „Reduced attendance‟ scenario)

4 WAST reduces its ambulance attendance rate to the English benchmark and 90% of

hospital handovers are achieved within 15 minutes (the „Full benefits‟ scenario)

Page 36: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

36

As Table 10 shows, in order to meet all the performance standards under the Base Case

scenario, WAST would require a minimum further 99 staff to enable it to produce the

necessary hours to fill the rotas. This calculation is based on the assumptions that the Trust

continues to operate with its current rates of overtime and planned relief and that hospital

delays remain at the level observed during the reference period for this report. If the Trust

reduces its reliance on overtime to the level that is required to cover frictional factors such as

overruns at end of shifts and occasional unexpected sickness a further 163 staff would be

required and this would add a further £1,679,000 to the cost base. Moreover, increasing the

relief factor from 26.8% to 35% would require WAST to employ a further 82 staff and would

add a further £3,206,000 to the total cost bringing the total additional cost of filling the new

rotas to £8,647,000

Table 10 - Staff requirement – Base Case scenario

Table 11 shows the potential reductions in the ambulance hours and the related financial

savings that could be achieved relative to the Base Case Scenario if WAST were able to

operate based on a different interpretation of the 14/18/21 minute standards and was also

able to reduce the number of cases where an ambulance attendance was required at

Category B and Category C calls. This shows that the number of ambulance hours required

could be reduced by a total of 1524 per week from these initiatives. Moreover Table 12 also

shows that the required hours could be reduced by a further a further 710 hours per week if

90% of hospital handovers could be achieved within 15 minutes.

Page 37: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

37

Table 11 – Savings in unit hours and cost relative to ‘Base case’ scenario

The staffing and financial implications of these different scenarios relative to the position in

2008/9 is summarised in Table 12.

Table 12 Staff requirement and costs under alternative scenarios

Page 38: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

38

This shows that under the Current Response model where WAST is not required to send an

ambulance to every Category A and Category B incident to meet the 14/18/21 minute

standards, but where the full benefits of the new response model have not yet been realised,

WAST would require 57 more staff at an additional cost of £2,370,000 in order to meet all its

performance targets on the assumption that it maintained its current levels of overtime and

relief. The staff requirement would increase to 224 at an additional cost of £4,017,000 if

WAST were to reduce its reliance on overtime to cover core shifts. The staff requirement

would increase further to 305 staff at an additional cost of £7,144,000 if WAST were to

increase its planned relief factor from 26.8% to 35%.

Table 12 also shows that if WAST were able to obtain all the potential benefits of lower

attendance rates and reduced delays at hospital, it would be able to meet all its performance

targets and standards with 33 fewer staff and at a cost that was £1,876,000 lower than in

2008/9 based on the current levels of overtime and relief. The staff requirement under this

scenario would increase to 110, but the overall cost would still be £386,000 lower than in

2008/9 if WAST were to operate without relying on overtime to fill core shifts. The staff

requirement under this scenario would increase further to 184 at an additional cost of

£2,497,000 if WAST were to increase its planned relief factor from 26.8% to 35%.

4.6. Financial analysis

Our financial analysis consisted of the following four distinct work streams:

The identification of the income streams for WAST for the year 2008/09,

The development of a fully absorbed cost model identifying the cost of delivering

EMS in Wales based upon 2008/09 figures,and

A financial summary of the impacts of the various proposed changes within the

report.

Page 39: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

39

4.6.1. Income

Based upon the information provided by WAST, the Trust received the following income in

2008/9:

Table 11 – WAST sources of income 2008/9

4.6.2. Fully absorbed cost model

In order to ascertain the costs of delivering EMS within Wales we have produced a cost

model which aims to identify the fully absorbed cost of the services using the methodology

set out in Appendix 3.

For the purpose of this exercise, the Air Ambulance Service was included within the analysis

of the cost of providing the EMS service

The results from the summary cost model for the year 2008/9 are as follows:

Page 40: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

40

Table 12 – Fully allocated cost by service line

By comparing the income in Table 11 with the fully absorbed costs of each of the service

lines we can see that based upon the model developed there was a shortfall in EMS funding

in 2008/9 of £5,747,000. However it must be noted that the cost model has not been built on

a detailed analysis of cost consumption, rather on an agreed approach to allocating

overheads, the result of which is that there could be a margin of error in the allocation of

overheads.

4.6.3. Financial summary

Whilst the work we have performed relating to income and fully absorbed costs highlights a

potential shortfall in EMS income of £5.7m we believe that further activity analysis is required

in order to identify the „true‟ costs associated with delivering each of the activities undertaken

by WAST. Clearly there is an element of cross-funding within the Trust and therefore the

Trust should consider ways in which to bring each of its “service lines” into a recurrent

breakeven position.

We were also asked if the achievement of a £2m costs saving for EMS was possible. There

are a number of areas where we believe further investigation may result in opportunities for

significant savings. These include:

Control & Administration - Based upon the comparison table above we believe that

there may be potential savings within the back office functions at WAST and this is

an area that needs further examination. For example WAST has over 100 more

members of staff in either the Control & Manager and Administrative roles than

SWAST. Furthermore the comparison of numbers is not on a like for like basis with

the numbers for WAST being based upon whole time equivalents and the numbers

for South Western Ambulance Service being based upon total people employed.

The cost of staff and directors at WAST is £91,098,000 with an average costs per

whole time equivalent of £33,678. The average cost of staff employed at South

Western Ambulance Service WAST is £31,945 but as mentioned before the

numbers are not wholly comparable. However what is clear is that the number of

staff employed by WAST in these non frontline roles is significantly higher than the

number employed by South Western Ambulance Service The possible savings

Page 41: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

41

would depend upon how many of these non frontline roles are indeed excessive,

below we summarise the potential savings:

5% of roles could be removed - £168,390

10% of roles could be removed - £336,780

25% of roles could be removed - £841,000

50% of roles could be removed - £1,683,900

We have not undertaken any analysis in the course of this review to validate the

extent to which these activities might be streamlined and savings realised. Moreover,

the above numbers assume a linear relationship which may not be true.

Nevertheless, they serve as an indication as to the potential savings that might be

available.

Fleet Costs - A further area of potential cost savings would arise if WAST moves

towards a model that utilises more RRV‟s and fewer double staffed ambulances.

The scope for such savings in the fleet running costs is suggested by a comparison

of fleet costs with South Western Ambulance Service. The average fleet cost per

vehicle at South Western Ambulance Service is £20,554 which is 18% lower than

the average fleet cost at WAST of £24,182.

Based on the assumption that the average cost of an RRV for WAST is £10,000 per

year and the average cost of a double staffed ambulance is £30,000 per year, WAST

would obtain savings of £280,000 per year from the change in the mix of vehicles

that would result under the Full Benefits scenario

Operating centres and control rooms - One factor that has a significant effect on the

cost base of WAST is the number of operating centres and control rooms that the

Trust currently supports. At present WAST operates from three operational centres in

St Asaph, Cwmbran and Swansea and operates five control rooms including both the

EMS and NHS Direct locations. In the course of this review we have not undertaken

any analysis of the potential opportunities that might exist for reducing costs through

a reduction in the number of control rooms and operating centres and therefore we

can not provide any estimate of the potential savings that might be available from this

area. However, this is an area which should be examined in the context of any

detailed review of the Trust‟s cost base.

At the same time, the additional resources that WAST requires in order to meet its

performance targets will increase the Trust‟s cost base. The tables below summarise the

financial impact of the proposed changes to the operating model.

Table 15 shows the financial impact of funding the „Base Case‟ operating model based on

the changes to staffing levels that are required to fill the new rosters, the costs of reducing

overtime from the current level of 19% to 5% and an adjustment to change relief from the

current 26.8% to 35%. Table 16 shows the associated costs of moving to the new model

using more RRV‟s and fewer double staffed ambulances and assuming that all the benefits

identified in Section 4.5 in terms of reduced ambulance hours have been realised. (Please

Page 42: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

42

note that these costs relate simply to the costs of frontline staff and do not reflect any

savings associated with the change of fleet.)

Table 15 – Funding requirements for the ‘Base Case’ operating model

Table 16 – Funding requirement for the ‘Full Benefits’ operating model

Based upon the information above it is clear that if WAST were to start to change its

operating model in line with the recommendations in this report at the same time as reducing

the levels of overtime worked and increasing the relief factor by the full amounts indicated

there will be a significant level of investment required. However against this investment

there should also be savings in fleet costs and other operating efficiencies associated with

changing the model which have not been quantified at this stage. It should also be noted

that the additional staff required to fill the new rosters are to deliver a 95% performance

against the 14/18/21 minute standard, not the Category A 8 minute AOF targets, which as

stated earlier can be met from existing resources under the conditions identified

In terms of the question of what level of cash releasing CIP the Trust can achieve, based

upon the above and assuming that both relief and overtime are operated at the levels

specified, it is clear that under the current operating model the Trust is not able to operate a

Page 43: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

43

cash releasing CIP whilst at the same time delivering its AOF performance targets.

Moreover, the Trust will require additional funding if it is to meet the 14/18/21 minute

standards. However, if the full benefits of the new operating model could be obtained the

Trust would require an additional funding of only £2.5mil, and offset against this could be the

potential savings highlighted above.

4.7. Other findings

In the course of our work we also reviewed WAST‟s operational readiness to adopt the

practices that are advocated in this report in comparison with best practice at other

ambulance trusts. These included a review of Control room processes, Clinical practices

and the overall organisational structure of the Trust. Our findings in respect of these

considerations are set out below

4.7.1. Control room processes

WAST currently operates three Control Rooms, one based in each of the three regions.

Each of the control rooms is managed by a Utilisation Manager and performance

management takes place within the regional management structure. At the time of our

review, control practices varied across the different regions and we identified a number of

areas where there were opportunities for improving the efficiency and effectiveness of the

control processes.

Across all the three control rooms the dispatch process was slower than we would have

expected despite the fact that the information from the call takers was available to

dispatchers almost immediately. The approach to vehicle deployment relied heavily on the

use of double staffed ambulances and was inhibited by the absence of system status

planning software, mobile data and vehicle location technology which the Trust plans to

introduce later this year. In addition, we believe that there is potential for improved utilisation

of community and static responders with appropriate investment in the necessary

infrastructure to support this.

The Trust‟s proposed new structure which includes a Trust wide head of the Control should

serve to improve and coordinate operational practices across the three Control Rooms and

accelerate the work that is already underway within the Trust‟s National Control Steering

Group to standardise control processes and systems. Moreover, further improvement in the

effectiveness and efficiency of Control Staff should be possible through consolidating the

performance management arrangements that WAST has recently put in place. In this

context, the Trust is currently working with Landmark Consulting to implement a structured

approach to performance management that will apply across the three control rooms and the

managers in the South East have already received training in this process.

The Trust has also recognised the need to improve its deployment and utilisation of Rapid

Response Vehicles (RRVs) and has been in discussion with Staff Side Organisations

concerning the introduction of modern operational procedures. The current operating model

predominantly uses double staffed ambulances and therefore any change in the model so as

Page 44: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

44

to make greater use of Rapid Response Vehicles would require a material change in

organisational culture and behaviour.

There is also significant scope for WAST to leverage the benefits of the co-location of NHS

Direct within the Control Centres and to increase the proportion of Category C calls that are

handled by means of telephone triage. In particular, the move to Vantage Point House in the

South East Region provides a control room that, with the appropriate technology, would be

capable of providing an integrated single point of contact for the local health economy.

We understand that WAST is developing a Clinical Contact Strategy for the advancement of

its Control Centres and discussion is taking place with some „Out of Hours GP‟ providers

about further opportunities that exist for integrated working. Systems for managing Category

C calls are also being developed in conjunction with WAG and we understand that WAST

have worked closely with WAG to establish alternative pathway of care for low acuity calls

which draws on similar work that has been undertaken elsewhere in the UK. A number of

PDSA cycles have been used to establish the benefits of providing telephone nurse triage

for Category C calls. Based on this work we have been informed that the Clinical Desk

model is currently operational in both Central and West and the South East regions and is an

integral part of the new Clinical Control Centre strategy.

The Trust has also included within the 2009-2010 LDP submission its intention to link CAS

(the NHS Direct Software) and the Alert 2000 CAD (the Ambulance software) so as to widen

the availability of Category C triage to all Nurses in NHS Direct Wales. The Trust has also

submitted an „Invest to Save‟ bid in collaboration with health partners to implement NHS

Pathways as a single clinical triage platform within Wales.

4.7.2. Clinical procedures

From our review we believe that there is scope for further improvements in clinical practice

at each stage of the patient pathway. In this context it is essential that a common vision is

agreed for WAST among all the key stakeholders which can then be communicated clearly

to staff. This vision should be of a clinical service with a huge role to play in the delivery of

the unscheduled care agenda both nationally and locally as outlined in this report rather than

solely as an emergency response and transportation service. Moreover, the clinical strategy

needs to be understood within the Trust as clearly complementing the delivery of

performance standards. As research demonstrates, clear clinical gains can be made from

early intervention by trained health professionals.

In the control rooms we believe that significant opportunities exist for greater integration

with NHS Direct and Out of hours providers and that these opportunities should be

maximized. In particular, the clinical advice that is already available to callers to NHS Direct

could be made available more extensively to EMS callers as well as to paramedics and other

ambulance staff. There is also an opportunity to better influence the management of patients

across the system by capacity managing ambulances going to the various A & E

departments and in time beginning to develop other alternative points of access.

We also believe that the clinical supervision and support available to operations teams

could be enhanced. During our review we saw little evidence of any input from the control

room for front line staff if they have a problem and it was also difficult to ascertain the

Page 45: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

45

numbers of paramedics, technicians and clinical team leaders at each station. Moreover,

there was little evidence of sharing best practice either within or between Regions. We also

understand that, although WAST has now established a clear plan for providing clinical

training for staff at all levels, there have been difficulties in releasing staff to undertake the

training at the current levels of overtime and relief.

A further issue is that turnaround times at hospitals vary widely. There is currently limited

understanding of what factors influence these times and little sharing across Wales of best

practice developments used at local level. WAST is working towards alleviating the delays

and the use of the touch screens at the hospitals to record handover times is a very positive

initiative, but this is mitigated by poor processes in the hospitals which need to be addressed

in order to solve the ongoing problems caused for WAST by extended hospital delays.

WAST recognises the need to strengthen its clinical processes and a number of initiatives

are currently under way that are designed to address these issues. We understand that a

draft clinical strategy and vision document has recently been developed which is

underpinned by various other strategies e.g paramedicine, nursing, clinical effectiveness and

Partners in Health. The Clinical Contact Strategy is also in final draft. Both documents will

now be taken through a consultation process to ensure wide and meaningful stakeholder

engagement and input before the documents are presented to the Trust Board. In addition,

the current implementation of the new role of Clinical Team Leader should ensure that

paramedics have clinical leadership at a local level. WAST is also introducing a new role of

Specialist Practitioner which will take paramedics/nurses through the novice to expert

framework and will complement the role of the Clinical Team Leaders. The development of

these new roles and indeed the CCS is dependent on the development of robust clinical

supervision and mentorship networks throughout WAST. Regional Professional Advisory

Groups and the National Clinical Advisory Group will ensure professional issues are

addressed, action taken and lessons learnt and shared across the Trust.

4.7.3. Organisational issues

The fact that WAST operates from three regional offices and the senior management team

are spread across these three locations makes the management of the Trust a particular

challenge. A new organisation structure has recently been introduced with the objective of

streamlining the management structure and a number of senior appointments have been

made or are currently planned, including a new Director of Human Resources and a new

Regional Director in Central and West. However at the time of our review the Trust did not

have a substantive Operations Director, two of the three Regional Directors had only

recently been appointed and there was no head of control for the Trust as a whole. It will

therefore be important that the Trust ensures that the new management structure is

implemented effectively and that there is a strong focus on the effectiveness of the senior

management team.

A further issue for WAST is the current arrangement for funding and performance

management. HCW is the principal funding organisation for the EMS service in WAST, but it

does not have responsibility for commissioning other elements of the urgent care system.

However, WAST also receives funding from a number of other sources including NLIAH and

WAG. As a result, there is currently no one organisation that is responsible for funding the

Page 46: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

46

fully loaded cost of providing the EMS service. The basis on which funding is currently being

provided and will be provided in the future (whether on the basis of journeys, attendances or

incidents that are responded to) is also unclear due to the current reorganisation of the NHS.

The arrangements for the performance management of WAST are currently through the

North Wales Regional Office and it is unclear how this process holds the two parties to

account for the delivery of their respective responsibilities. The establishment of the new

LHB structure provides the opportunity to revisit this structure possibly through the

appointment of a nominated LHB to act as the lead commissioner and performance manager

for WAST.

5. Conclusions and recommendations

5.1. Conclusions

WAST has made significant progress since the original Audit Office report in 2006. There

have been a number of positive developments in the way that the Trust is now operating and

Category A performance in particular has improved significantly during this time. However,

the results of this review show that that there are still some fundamental issues that are

preventing WAST from performing at a level that is comparable with similar organisations

elsewhere in the UK. As a result patients in Wales are not receiving a level of service that is

commensurate with that achieved by other ambulance trusts elsewhere in the United

Kingdom..

The key findings from our benchmarking analysis and our asessment of the the current

efficiency and effectiveness of WAST are as follows

WAST‟s performance in relation to the Category A 8 minute target has improved

significantly since the beginning of 2007. However there has been little or no

improvement during this period in relation to the Category A and Category B

14/18/21 minute standards.

Although Wales covers a larger geographical area than other ambulance trusts in the

UK, the proportion of EMS activity that occurs in towns and cities in Wales is similar

to that of comparable ambulance trust areas in England

Wales experiences a relatively high number of 999 calls per head of population and a

relatively high proportion of these calls result in a patient being transported to

hospital. This results in pressure being placed on WAST and on hospitals in Wales

that we believe could be alleviated if suitable call triage and assessment procedures

were used and alternative care pathways were available for patients

We estimate that the total cost that WAST incurred in providing the EMS service in

2008-9 was £101.3 mil. WAST received £95.6 mil of funding for the EMS service in

2008-09 from HCW, NLIAH and the Air Ambulance Charity. The difference was

funded by income for other purposes e.g. ARRP.

Hospital delays have a significant impact on the ability of WAST to meet its

performance targets. During the reference period for our review, WAST would have

required an additional 900 ambulance hours per week in order to compensate for the

delays in handing over patients at hospital at an annualised cost of £2.3 mil per year.

This effect is of particular significance in the South East region of the Trust.

WAST‟s performance with respect to the initial phase of allocating a vehicle to a 999

call compares poorly with other ambulance trusts in England. A significant

contributory factor to this performance gap is the lack of an Automated Vehicle

Location System (AVLS) and related mobile data systems on EMS vehicles in Wales.

This makes it difficult for WAST reliably to locate and deploy the most appropriate

vehicle to respond to a 999 call.

Once the benefits of its investment in AVLS and mobile data are available, WAST

could meet the current Category A 8 minute targets both at a national and LHB level

with its current staffing levels and overtime rates and with the level of hospital delays

that occurred during the reference period for this review. In order to do this WAST

would need to accelerate the implementation of a deployment strategy that

o is based on 7 minute deployment areas in the more densely populated areas

o matches resource more precisely to the location of activity

o relies more extensively on the use of single manned response vehicles, and

o makes more extensive use of Community First Response schemes in less

densely populated areas as the initial response to Category A incidents.

The current level of staffing does not allow WAST to meet the 14/18/21 minute

standards and also requires a reliance on high levels of overtime to fill core shifts. In

addition, the shortage of staff in certain areas is preventing WAST from undertaking

sufficient ongoing professional training. Based on WAST‟s current levels of overtime

and planned level of relief, we estimate that the cost of the additional staff required to

meet the current 14/18/21 minute performance standards would be £3,744,000. This

would rise to £8,647,000 if WAST were to operate with no reliance on overtime to

cover shifts and with the level of cover for holidays, sickness, training and other lost

hours that was recommended in a Department of Health paper published in April

2007 setting out best practices in managing ambulance trusts

If it were fully resourced in accordance with the recommendations in this report,

WAST should be able to achieve a Category A 8 minute performance target of at

least 70% for the whole of Wales as well as meeting all the 14/18/21 minute

standards.

The current practice with respect to the 14/18/21 minute standards means that

WAST sends more double staffed ambulances in response to lower acuity 999 calls

than occurs at some other ambulance trusts. As advocated in this report, an

alternative approach which distinguishes more clearly between the requirement for

an appropriate initial assessment of the patient‟s requirements and the subsequent

provision of transportation once it has been determined that the patient needs

transporting to hospital could significantly reduce the number of ambulance hours

that WAST requires and also reduce the number of cases where the patient is

transported to hospital. It should be noted however that a change of this type will

require a significant change in practice within WAST as well as actions by other

stakeholders to ensure that alternative pathways are available for patients.

Consequently the benefits from this change are likely to take between 3 and 5 years

to be fully realised.

If WAST were able to match the levels of ambulance attendance and transportation

that are achieved in some trusts in England it could reduce the number of ambulance

hours required by around 410 per week by comparison with the level that was

planned in 2008/9. This would save around £1,025,000 per year in staff costs

If hospital handover times were improved so that only 10% of hospital handovers

took longer than 15 minutes this would reduce the number of ambulance hours

required by comparison with the reference period for this review by 710 per week .

This would save a further £1,966,000 per year.

If WAST were able to obtain the full benefits from lower ambulance attendance rates

and reduced hospital delays it should be possible for the Trust to meet both the AOF

Category A 8 minute targets and the 14/18/21 minute standards with a staff cost that

would be £1,876,000 lower than the level in 2008/9 based on the current overtime

and planned relief levels and would be £2,497,000 higher than the 2008/9 levels

based on the lower overtime and higher relief scenario.

If WAST were to change its operating model in the way that is advocated in this

report and was also able to obtain the full benefits of lower ambulance attendances

and reduced hospital delays outlined above, it should also be able to realise savings

of up to £280,000 in fleet costs as a result of greater use of cars and less use of

double staffed ambulances.

WAST may also be able to realise additional savings in the following areas

o reducing its administrative overheads

o reducing the number of operating centres and control rooms

It should however be noted that we have not examined these areas in any detail

during this review.

In addition to the detailed findings of our analysis set out above, we have also identified a

number of organisational issues which we believe need to be addressed if WAST is to

achieve a successful transition to the new approach to the delivery of its services that is

advocated in the report. In particular

The challenges of agreeing a common vision between WAST and its many

stakeholders about the role that WAST should play in the delivery of urgent care

across Wales has previously made it difficult for the Trust to plan its future direction

with any certainty and to communicate this to its staff. At the time of this review,

WAST has submitted a vision statement to NHS Wales for comment and

consideration and is also working with the seven new LHBs to include key objectives

within the LHBs own Urgent Care Plans. This offers an opportunity to establish a

jointly agreed role for WAST that will form the basis for the implementation of the

recommendations in this report

The geographical spread of the Trust, the requirement for senior management to be

located in three different regional centres and the amount of change in the senior

management team has made it difficult to establish a stable management structure.

The new management structure that has recently been introduced provides a

framework within which WAST can create the senior management team that will be

required to implement the strategy that is recommended in this report

The quality of clinical oversight, supervision and training has not had sufficient focus

at a time when the Trust has been under pressure to deliver performance. This has

been recognised by WAST and a number of initiatives are currently under way to

address these issues. However, the pressure on resource and the low levels of relief

continue to make it difficult for the Trust to release staff to undertake appropriate

levels of clinical training

The funding arrangements for WAST have been unclear in the past and require

clarification in the new NHS structure so that the link between funding and service

delivery can be made transparent

The current commissioning and performance management arrangements for WAST

do not facilitate clear lines of accountability between WAST and its commissioners

and performance managers for the delivery of the EMS service

Although WAST could achieve the AOF Category A 8 minute target for the initial

attendance at life threatening incidents with its current resource based on best

practice call cycle performance and the current levels of overtime and relief, the

current level of recurring funding that WAST receives is insufficient to enable it to

achieve the 14/18/21 minute standards. We therefore believe that WAST will require

additional funding in the short term in order to provide a fully effective EMS service

that delivers appropriate levels of clinical care to patients.

Nevertheless, our review has confirmed that, following the merger with NHS Direct, WAST is

uniquely placed to contribute to the delivery of a high quality urgent care service in Wales.

Moreover, there are significant opportunities for WAST to change the way that it operates so

that it is able to deliver an improved and more cost effective service. Indeed we see no

reason why these standards should not be comparable to those that are achieved in

England. In particular we believe that, based on the resources that we have recommended,

WAST should be able to achieve a performance standard of at least 70% for Category A

performance and also to meet suitably defined 14/18/21 minutes response and

transportation standards for both Category A and Category B incidents. It should also be

50

possible for WAST to reduce significantly the current reliance on emergency ambulances for

transportation to hospital and also to reduce the overall number of patients who are

transported to hospital by a combination of suitable initial assessment and the availability of

alternatives to hospital for patients to access. However, for these benefits to be achieved

WAST needs to work closely with the rest of the urgent care system in Wales and to

operate within a more clearly defined planning and performance management structure than

has occurred previously.

The new LHB structure which becomes operational on 1 October 2009 provides a unique

opportunity to establish an agreed strategy and a new governance and operating framework

for WAST based on these findings and our recommendations which are set out below. .

5.2. Recommendations

In line with our findings and conclusions set out above we would like to make the following

specific recommendations with respect to the future direction of the Welsh Ambulance

Service

WAST‟s vision of its future direction needs to be based on the principles set out in

this report, agreed with the Welsh Assembly Government, the new LHBs and other

key stakeholders and communicated to its staff

WAST should establish with WAG and the LHBs a clear interpretation of the 14/18/21

minute standards that apply to both Category A and Category B incidents

WAST should agree with the LHBs a plan to significantly reduce the ambulance

attendance and transportation ratios for Category B and Category C calls.

WAST should ensure that the structured approach to the deployment of RRVs and

other initial response vehicles set out in Section 3.2.2 above is implemented

effectively

WAST should ensure that the benefits of the new management structure are realised

as soon as possible

The Director of Operations should ensure that the Trust‟s performance management

and performance improvement processes are reinforced, deliver consistency of

performance and are used to enable the changes that are recommended in this

report. This should include a mechanism for defining and sharing best practice for

operations staff across the three Regions

The National Control Development Lead should establish common operational and

clinical practices that will operate in each of the control rooms and develop training

programmes and performance management methodologies for control room staff

Page 51: Efficiency Review of The Welsh Ambulance Services … · Efficiency Review of The Welsh Ambulance Services NHS Trust Undertaken by Lightfoot Solutions in association with Lis Nixon

51

WAST should improve the clinical input that is provided from the Control rooms for

both patients and front line staff and make better use of the potential that exists from

the co-location of ambulance control and NHS Direct through the implementation of

the Clinical Control Room Strategy

WAST should continue with its plans for the introduction of Specialist Practitioners

and Clinical Team Leaders

WAST in partnership with the LHBs should proactively seek to increase the number

of co-responder schemes and community responder schemes that operate in the

semi urban and rural areas and should ensure that there is an appropriate support

and deployment infrastructure to support this.

WAST should establish a clear staff development plan and agree with the LHBs a

level of relief that will allow staff to undertake the training that is required to maintain

their ongoing professional development

WAST should proceed with its plan for the implementation of a new CAD system as

soon as possible. This is necessary to enable WAST to improve service resilience by

allowing the sharing of information across the control rooms as well as enabling the

Trust to benefit from additional functionality that is not available in the current legacy

CAD system

WAST and the LHBs should review the Trust‟s current regional configuration in the

context of the proposals for communications hubs and the need to deliver a cost

effective control function.

In preparation for establishing new funding contracts, WAST should complete a

review of the fully loaded cost of providing the EMS and PCS services in order to

establish a sound basis for establishing the funding requirements and the contract

currency for the two services.

WAST should agree with the LHBs an appropriate subset of the measures outlined in

this report that can be used to benchmark its performance on a regular basis against

similar ambulance trusts elsewhere in the United Kingdom

WAG in conjunction with the new LHB‟s should develop and agree the future

planning and delivery arrangements for WAST, ensuring a clarity and focus upon

outcomes and performance

WAST should undertake a strategic review of its support services to establish

whether there are alternative ways in which these services could be provided at

lower cost

WAST and the LHBs should develop a fully costed plan to implement the actions

required to deliver the new delivery model and should establish a joint programme

management farmework to oversee the implementation of the plan

Appendix 3 Cost model methodology

The cost model that is summarised in section 4.7.3 was developed using the following

process:

The year to date costs for period 11 were extracted from the cost centre reports at

Oracle Level 2 (Directorate Level);

The costs and income elements were identified on the cost centre reports;

The costs were then reconciled at the directorate level to the total costs reported for

the entity (Ambulance Trust Level);

We removed the income elements from the “costs” that are to be used in the costing

model;

The month 11 costs were extrapolated into a 12 month costs (agreed with WAST as

a factoring of 11*12);

We then identified which facilities should be costed within the Emergency Medical

Services and agreed these with WAST, they are:

o Provision and operation of Emergency Ambulances;

o Provision and operation of Air Ambulances;

o Operation of WAST call centres; and

o Despatch of all ambulances.

We identified which of the directorates could be directly attributed to EMS and treated

other directorates as “overheads”;

We then allocated the “overhead” directorates into the operating directorates simply

by using the total costs of the operating directorates to apportion the overheads;

Totalled the direct operating costs and the allocated overhead costs to give a fully

overheaded cost for each of the “EMS” directorates;

From the overheaded “EMS” directorates, allocated the costs into the operating

areas (Oracle P3 Level) that they cover using the direct costs;
