THE COST OF LONG TERM DISABILITY RESULTING FROM
ROAD TRAFFIC ACCIDENTS
Interim Report
i. INTRODUCTION
During the period 1982-85 the Department of Orthopaedic Surgery at the
University of Manchester, under contract to the TRRL, carried out a study into
the long-term after effects (disability at 6 months) on people who had been
injured as the result of a Road Traffic Accident, (Galasko et al 1986). The
injuries identified as having the greatest long-term effects were fractures
of the upper or lower limbs and 'whiplash' i.e. soft tissue cervical spine
injury; these two injuries alone constituted 40 per cent of all injuries
resulting in long term disability.
Patients with these injuries were considered to be a readily identifiable
group worthy of further study and as a result of these findings the Department
of Transport (TRRL) commissioned a follow-up study. This sought to identify
the resources required to treat these injuries and to calculate the costs
associated with the long term effects, which are not at present fully
incorporated in national road accident costings. A principal objective of the
current study was to remedy this anomaly by calculating the costs not only to
individuals but to the community as a whole.
This interim report looks at the financial cost of both groups of injuries
during the first year after an accident (which occurred between July 1987 and
July 1988), by which time each patient had been followed up for one year and
had been interviewed and assessed on three occasions.
2. METHODOLOGY
The study commenced in June 1987 and was planned initially to last for a
period of three years, recruiting patients who attended the Accident and
Emergency Departments of three hospitals in the Greater Manchester area as the
result of a road traffic accident.
The hospitals involved were Hope Hospital, Salford; North Manchester General
Hospital; and Stockport Infirmary.
Because of the in-depth nature of the study it was possible to assess only
about one quarter of all patients who attended with the relevant injuries: for
whiplash patients 333 of 1334 were assessed (25.0 per cent) and for fracture
patients 82 of 395 (20.7 per cent). Patients were however randomly chosen for
inclusion in the study. For each patient, information on age, sex, date of
accident, injuries sustained and length of hospital stay was obtained from
hospital records.
All patients recruited to the study were to be interviewed initially at the
time of the accident, or as soon after as possible, and thereafter at six
monthly intervals until the end of the study or when they declared themselves
to have returned to pre-accident fitness. The interview questionnaire sought
to obtain information on the use of hospital facilities, general practitioner
attending and any change in work routine or time off work, or other
activities. It also sought information on compensation claims, changes in
income and any Social Security benefits being claimed. Finally, change in
lifestyle and activities of daily living were assessed.
The costs of appropriate outpatient facilities and other health department
resources used by these patients were obtained directly from the Department
of Health via the respective District Finance Departments. Information on
social security benefit rates were obtained from the Department of Social
Security. The majority of other cost information was obtained directly from
patients. All costs given refer to 1988.
3. POPULATION CHARACTERISTICS
3.1 Injury by road user type
The incidence of "whiplash" injury, fractures and the combination of both
injuries together is given for each type of road user in Table I.

The road user groups who sustained the majority of 'whiplash' injuries were
car drivers and passengers, though it is of note that one pedal cyclist
sustained a 'whiplash' injury and another a combination of 'whiplash' and
fracture. Motor cycledrivers and pedestrians sustained the highest number
of fractures. Seven out of the eight patients with "whiplash" and fracture
were car occupants.
3.2 Injury by age
The incidence of injury by age is given in Table 2.

Two hundred (60 per cent) of the 333 'whiplash' casualties were in the 15-34
years age group. Similarly 45 out of 82 (56.1%) fracture casualties were in
this age group. The remaining patients with fractures were fairly evenly
distributed amongst the other age groups, whereas 82.5 per cent of patients
with a 'whiplash' were under 45.
3.3 Disability rate at 6 months and 12 months
By the end of one year following the accident, 44% of 'whiplash' injury and
60% of fracture injury patients were still not totally recovered (Table 3).
The highest disability rate was for patients with a combination of both
injuries, 88%. At the end of the first year nearly half the sample 48% still
had some physical and/or psychological problem. In the present context
patients were still considered to have a disability if they had not returned
to their pre-accident fitness. This was based on self assessment backed up
by a detailed questionnaire and interview with a research sister.

3.4 T i m e off work
The number of working days reported lost for all three injury groups was high.
The average number of days lost for fracture injuries was 72, for "whiplash"
injuries 31, and for whiplash and fracture together 95 days. These are
average times off work to date, patients having been followed up for one year
only; some had not yet returned to work. Further follow-up will be required
to determine whether these patients will ultimately return to work or remain
permanently unemployed. The personal cost~of these lost days is quantified
in Section 4.3. In addition to personal losses these working days represent
a loss to the community in terms of reduced output. This aspect is considered
in Section 5.
4. COSTS
In the following Section the cost of disabling injuries is assessed under
three headings; the figures given are 1988 costs. These are (i) the cost to
the Department of Health (ii) the cost to the Department of Social Security
and (iii) the cost to individual patients. The first two of these categories
effectively represent the cost of these disabling injuries to the community
as a whole. In addition, days off work represent a Cost to the community in
terms of lost production and loss of tax revenue.
The cost to the Department of Health is made up of several components the
more important ones of which are examined in the following sections. Unless
otherwise stated the number of patients" given in each table relate only to
those actually receiving the relevant treatment or using the services. A
summary of all Health Service costs to those receiving treatment is then given
in Table 9 with a summary of detailed costs averaged over all patients given
in Table I0. A detailed discussion on costs follows in Section 5.

4.1 Health service costs
4.1.1 Accident and Emergency costs.
All patients in this study had made an initial visit to the Accident• and
Emergency Department (Table 4). Although 'whiplash' injury patients had more
review visits at the A&E Department than those with fractures, the average of
2.1 per cent visits per patient is comparable to the fracture group where the
average was 1.8 review visits. Fracture patients tended to the referred to
a Fracture or Orthopaedic Clinic after an initial visit to the Accident and
Emergency Department. The total number of patient visits to Accident and
Emergency was 762, at a cost of £21 per visit, giving a total cost of £16,200.
4.1.2 In-patlent COSTS.
Sixty-five of the 423 patients were admitted to an Orthopaedic Ward and spent
a total of 1,590 days in hospital at a cost of £99 per day. The average
length of stay for a Road Traffic Accident fracture injury was 28.8 days
(Table 5). This was approximately three times the average length of stay for
orthopaedic patients who sustained injuries under other circumstances.
The figures in Table 5 represent on average for all patients although, two
'whiplash' patients requiring traction spent 18 days and 28 days respectively
6
in hospital which increased the average length of stay of 'whiplash' injury.
It should be noted that while 62 per cent of fracture patients required in-
patient treatment this was true of only 4 per cent of 'whiplash' cases.
Three patients, all with fractures spent a total of 22 days in the Intensive
Care Unit at a daily cost of £195; a total of £4,290. One fracture patient
spent 24 hours (one patient day) in the Neurosurgical Unit at a cost of £181.
The in-patient stays of these patients requiring special attention are
included in Table 5 but average in patient costs of £99 per day are assumed.
If the additional costs of Intensive Care and use of the neurological unit are
added the total costs are £1800 higher.

4.1.3 Outpatient clinic costs.
Table 6 gives a summary of the attendances and corresponding cost of patients
attending outpatient clinics.
The clinic most frequently attended, by all patients, was the Out-Patient
Fracture Clinic with a total of 501 visits at a cost of £28 per ~isit. Twelve
'whiplash S patients, although not having sustained a fracture, made a total
of 53 visits to a Fracture Clinic to be examined by an orthopaedic consultant.
Eighteen patients made a total of 115 visits to a variety of other Out-Patient
Clinics, either as a direct result of the injury or because of complications
arising from the injury e.g anti coagulant clinic after deep vein thrombosis.
4.1.4 Physiotherapy costs.
The attendance of patients for both NHS and private physiotherapy and the
associated costs are given in Table 7.
The Hospital Physiotherapy Service was used by 171 (40~) of all patients, with
a total of 2,279 visits at a cost of £5 per attendance. Fifty per cent of
both fracture and fracture plus "whiplash" patients required physiotherapy,
the average duration per session being somewhat higher than that of the 38~
of °whiplash s only patients who required treatment.
The average number of attendances for both groups of patients was high, being
just over I0 for "whiplash" and nearly 22 for fracture casualties. A few
patients (19) attended aprivate physiotherapist at an average cost of £15 per
session. These costs were met by the patients themselves or were covered by

private medical insurance. The averag e number of attendances was again high
particularly for whiplash patients (nearly 19).
4.1.5 Cost of appliances (Orthoses).
By far the most frequently used appliance was a collar. Three hundred and
seven 'whiplash' only patients (92%) were issued with collars as were all
eight 'whiplash' plus fracture patients. The cost of these collars was £5.35
each giving a total cost of around £1800. The only other aid supplied in any
significant numbers was a pair of crutches, of which 39 were issued to
fracture patients (48%) at a total cost of £520. Other items supplied in
limited numbers were sticks, slings and wrist braces, all at a cost of below
£5 each. These costs include no allowance for administrative or other
overheads. There are no costs available, at present, for supplying and
fitting artificial limbs.
Additional items of equipment, supplied to fracture patients, included five
wheel chairs at £161 each and five Zimmer frames at £12; a total cost of £865.
Three patients had to move house, including one to a disabled person's house
and six fracture patients had modifications carried out in their homes. One
had a hand rail installed in the shower, one had a hand rail installed on a
landing. These changes were arranged either privately or through the Social
Services Department; the costs are not known at this time. Two 'whiplash'
patients had to change to automatic cars as they could not cope with changing
gears in a manual car.

4.1.6 Cost of ambulance trips.
The average cost to the Ambulance Service for a five mile round trip was £5
per patient per mile, i.e £25 per trip. The total number of round trips for
all patients was 1,016 (Table 8). The greater number of these trips (890)
were for the transport of fracture patients who made an average of 12.7 trips
per patient. Five fracture patients had a much higher than average number of
trips (see Footnote.) The trips by 'whiplash' patients were usually
immediately after the accident, when they were taken to the Accident and
Emergency Department. The total overall cost for all patients was £25,400.

*Five fracture patients had a relatively high number of trips: one had 130, one 170, one 68, one 134 and one 61; These last two had to have amputations and required several trips to the rehabilitation hospital outside the catchment area. If these extra miles, outside the area, were to be taken into consideration, ambulance costs would be higher.
4.1.7 Summary of Health Service costs.
Other health services, outside the hospital, were also utilised in the
treatment of these patients. The costs incurred by general practitioners are
difficult to assess since the general practitioners service receives a fixed
annual amount per registered patient, depending on age, no matter how many
visits are made. Of four hundred and twenty three patients 409 were under 65
years of age, and three patients were in the 75+ age group. Annual costs per
patient for these age groups were £8.25 and £13.15 respectively. These costs
should clearly not be fully allocated to the injuries being considered here
but do give a measure of general GP costs. Further research is being
conducted to estimate the cost of each patient visit to a GP.
13
The District Nursing Service was used by five fracture patients, who had
visits totalling 9.5 hours at £9 per hour (£85), and one 'whiplash' patient
who had visits totalling 5 hours (£45).
A summary of all Health Service costs associated with these injuries is given
in Table 9.

4.2 Social Security Costs
The range of Social Security benefits available to those who are sick or
injured is very broad, the principal benefit available to those previously
employed being Statutory Sick Pay. A summary of the number of people claiming
this and other benefits is given in Table ii.
Statutory Sick Pay (SSP) can be claimed by people in employment who have paid
the required number of insurance stamps to qualify. SSP was paid in two
bands, a lower rate of £34.25 per week to applicants whose weekly salary
ranged from £40 to £79, and a higher rate of £49.20 per week to applicants
whose salary was over £79. Any sick leave after an initial three day
exemption period is calculated on the basis of a five day working week. This
has been taken into account in assessing the number of weeks of SSP paid
(Table ii).

Additional benefits cover all benefits quoted in the footnote to Table ii as
these are very varied and cover different periods of time, they are summarised
in terms of the number of patients claiming and the total amount claimed.
4 . 3 Personal Costs
A summary of income changes as a result of injuries sustained is given in
Table 12. One hundred and fifty seven patients (37%) lost some part of their
income through time off work, loss of bonus or overtime. These were
principally patients whose salary was not made up by their company al~hough
they may have claimed SSP, or who were self employed. 'Whiplash' patients
lost an average of £940, fracture patients £1,300, and 'whiplash' plus
fracture patients an average of £680. The total loss was £158,680. Four
patients, two with whiplash and two with fractures, actually gained income
after their injuries with transfer to a higher paid job e.g shop floor to
office for lighter duties. Details are given in Table 12.
These net losses (after any SSP payments) may, to some extent, be offset
against the gains in compensation claim settlements (Table 13). Settlement
figures ranged from £200 to £4,500. The discrepancy between income loss and
compensation obtained (Table 13) is apparent but this may be reduced when all
claims are settled.

5. DISCUSSION
In this section the findings of the study with respect to population and the
costs of injuries are assessed. The three components of injury cost are
discussed separately as in Section 4.
5.1 Population Characteristics
The RTA casualties with the specific injuries selected for study were made
up of approximately 80 per cent with a "whiplash" injury and 20 per cent with
fractures. Because of resource considerations it was only possible to assess
about one quarter of all patients with these injuries attending the A&E
Department over the chosen period, but the patients selected for the study
were chosen at random.
Patients with "whiplash" injuries were mainly in the 15-44 year age group.
This is characteristic of most RTA casualty populations. Patients with
fractures had a wider age distribution probably due to the much higher
proportion of pedestrians with these injuries.
The incidence of disability associated with both types of injury was
remarkably high, with nearly half of the total population having significant
problems one year after the accident. This compares with an incidence of
disability for all casualty types in the previous study of 24 per cent at six
months (Galasko et al, 1985). These results justify the selection of patients
with these injuries for further study. Provisional results of the ongoing
18
study suggest that a high incidence of disability remains at 18 months and 2
years after the accident.
These high levels of disability are not surprisingly, associated with extended
periods off work and limitations of other daily activities, ranging from an
average of one month for patients with a "whiplash" injury to over three
months for a combination of "whiplash" and "fracture"
5.2 Health Service Costs
The costs given in Section 4 were the costs supplied by the Department of
Health. These figures represent only the day to day running expenses of
providing the clinical services. The figures quoted include an average
additional administrative cost of 31 per cent to allow for the provision of
general services e.g. catering and laundry (see Appendix, for complete list
of services). The quoted costs, however, mustbe regarded as absolute minimum
values, as they make no allowance for such conventional overheads as
replacement, rebuilding, refurbishment, or indirect staffing costs; nor do
they take account of the utility cost of the buildings used. If allowance
were made for these factors overheads of the order of 100-150 per cent, could
be added, effectively doubling all the costs given here. This factor should
be borne in mind when considering the "real" cost of disabling injuries.
Further studies are being undertaken to attempt to quantify these overheads.
Whilst 62 per cent of fracture casualties were in-patients, at a cost of
nearly £3000 per casualty, this was true of only 4 per cent of whiplash cases.
On average those whiplash patients who were admitted spent one week as in-
patients in hospital whereas fracture casualties spent one month, which was
three times as long as for non RTA orthopaedic cases.
Although in-patient treatment represents the largest single contribution
towards Health Service costs a considerable amount of resources go into
providing for out-patient facilities.
The principal sources of out-patient treatment were either attendance at an
out-patlent clinic or attendance for physiotherapy. On average whiplash
patients had fewer visits to out-patient clinics than those with fractures
but made considerable use of both NHS and private physiotherapy facilities.
19
The majority of attendances for physiotherapy were made by "whiplash"
casualties, but fracture casualties required more attendances on average, per
patient receiving physiotherapy, (20.6) than whiplash casualties (9.6).
The nominal NHS cost of E5 per session for physiotherapy represents the
marginal cost of providing such a service;, a more realistic cost is likely
to be close to the £15 charged for private physiotherapy. Further
consideration of these costs is in hand.
The cost of mechanical aids represents an apparently small drain on resources
although 92 per cent of "whiplash"" patients were supplied with collars.
Again, it is questionable whether the quoted cost (just over £5) represents
the real cost to the NHS; it does not include any allowance for general
service costs or other overheads.
Many mechanical aids are not returned by patients and some costs would
probably be recovered by improving the rate of return. However, a pilot
study using a deposit system suggested that any cost savings were outweighed
by the administrative costs of operating the scheme.
In relation to the injuries considered, ambulance costs were second only to
in-patient costs as a drain on NHS resources. The average cost of £5 per
mile is probably realistic and the assumed cost per patient of £25 for
ambulance use reflects this cost. Fracture patients in particular made
considerable demand on the ambulance service averaging 13 trips per patient,
with a few patients making over i00 trips.
5.3 Social Security Costs
Social Security payments were found to represent the second largest component
(after Health Service costs) of road accident costs to the Community; they
amount to just under half of the health service costs. Those people
previously employed, who have time off work as a result of their injuries, are
entitled to statutory sick pay. This was claimed by just over half of both
fracture and whiplash casualties and represented approximately two thirds of
the total of the Social Security payments.
20
The remaining one third was made up of the several additional benefits which
may be claimed by those who are disabled and not in work.
Relatively few patients (Table ii) claimed what might be generally considered
as disability allowances ie mobility allowance, attendance allowance, severe
disability allowance or invalidity allowance. As the study progresses, it
will be interesting to see how the proportion of disability benefits, in
relation to total Social Security benefits paid, changes over time since the
accident.
5.4 Personal Costs
Just over one third of patients (37%) lost some part of their income through
time off work. The total financial loss to the 157 individuals (approximately
£150,000) represents a sum roughly midway between the Social Security and
Health Service costs.
These losses of direct income were to some extent mitigated by compensation
claim payments; 276 (65%) patients made compensation claims of which 83 (28%)
had been settled by the time of writing. These compensation settlements
amounted to approximately £i00,000 which represents about two thirds of total
income losses, although this figure is likely to increase with time. Many
more whiplash claims had been settled than those for fractures, probably
bcause the former reached a stable position more quickly than fractures.
However, there was some evidence to suggest that propensity to reach a
settlement was related to income group; this is being investigated further.
In addition to the personal losses discussed above, days off work as a result
of injuries sustained in RTA's represent a loss to the community as a whole.
In an industrial situation absence from work can result in lost production and
this factor should be taken into account when assessing overall costs. As
part of this study several firms in the Manchester area are being surveyed in
an attempt to quantify such losses; findings will be reported later. In
other work situations (eg offices) loss of output will be more difficult to
quantify. There is also a cost to the exchequer in terms of lost tax from
those no longer in employment.

6. SUMMARY AND CONCLUSIONS
This report presents the findings of the first year's follow up on a selected
group of 423 patients who had sustained either "whiplash" or closed fracture
injuries, with a view to establishing the incidence and costs of long term
disability arising from these injuries. The principal conclusions can be
summarised as follows:
i. The disability rate from both injuries was high; after one year 60 per
cent of fracture patlents and 44 per centof 'whiplash' patients had not
fully recovered from their injuries.
.
.
The average number of working days lost as a result of the injury was
high for both groups of patients, being 72 days for fracture patients
and 31 days for 'whiplash' patients.
On average, 'whiplash' casualties who were in-patients (only 4 per cent)
spent one week in hospital whereas fracture casualties (62 per cent)
spent one month, which was three tlmes as long as non RTA orthopaedic
casualties.
. The principal sources of out-patient treatment were out-patient clinics
and physiotherapy. The vast majority of fracture patients attended a
fracture clinic. Whiplash patients had relatively few visits to out-
patient clinics but made considerable use of both NHS and private
physiotherapy facilities.
. Physiotherapy attendances were frequent for both types of patients,
averaging over 20 for fracture patients and i0 for whiplash patients.
. Mechanical aids eg collars were used frequently by patients but were
relatively inexpensive. Ambulances, however, were also heavily used and
were second only to in-patient costs as a drain on NHS resources.
. The Health Service costs given in this report, although supplied by
the Department of Health, must be regarded as absolute minimum values
as they made no allowance for replacement or rebuilding costs. If

allowance were made for these overheads it is estimated that the "true
costs" would be about double the quoted costs.
Statutory sick pay was claimed (from theDepartment of Social Security)
by just under half of all patients, and represented approximately tw~ ~'~ • q •
thirds of the total of social security payments.
Only 36 patients (8..5%) have claimed disability benefits, such as
mobility allowance, but this needs to be monitored with respect to time
after the accident.
In terms of personal costs, just over one third of patients (37%) lost
some part of their income through time off work. However, these costs
were to some extent mitigated by compensation claim payments; 276 (65%)
patients actually made compensation claims, of which 83 (28%) were
settled at the time of writing.
Many more whiplash compensation claims have so far been settled than
for fractures, probably because the former tend to reach a stable
position more quickly than fractures.
In addition to personal losses, days off work as a result of injuries
sustained in RTA's represent a loss to the community in terms of lost
output and production. They also represent a cost to the exchequer in
terms of lost tax. The quantification of these factors is also being
considered in the study and will be reported later.
