Reducing the Risk of Musculoskeletal Disorders in Personal Support Workers
1
AbstractPersonal support workers (PSWs) are health care workers that assist those in need with day-to-day
activities. While PSWs work in a variety of settings, such as long-term care facilities and hospitals, this
Request for Proposal (RFP) focuses primarily on those that provide in-home care to patients. One groupthat PSWs regularly provide service to is seniors. In many cases, these seniors need help transitioning
from one position to another (i.e. bed to wheelchair). PSWs assist this movement by performing patient
transfers. This RFP focuses on the risk of PSWs developing musculoskeletal disorders while performing
these patient transfers.
Musculoskeletal disorders (MSDs) are injuries to the muscles, ligaments and/or surrounding bone
structures that do not develop from a singular event [1]. Factors that influence the development of MSDs
include posture, mechanical load and psychosocial wellbeing [2][3]. As well, this community faces a
heightened risk due to career-specific factors, such as funding and standardized training [4]. Health care
professional, such as PSWs, report one of the highest rates for development of MSDs [5].
This RFP seeks solutions to help reduce the likelihood of PSWs developing MSDs. Potential solutions
should seek to both minimalize the physical factors, while also being more accessible for PSWs with
regard to the career-specific issues. Reference designs to current patient transfers aids are included to
illustrate current industry standards, although the design team should not feel limited to any such design.
Stakeholders related to this need will be outlined, identifying their particular design concerns. Finally,
design requirements will be provided in order to create a design space for potential solutions.

Reducing the Risk of Musculoskeletal Disorders in Personal Support Workers

1IntroductionThis Request for Proposal (RFP) focuses on the Personal Support Worker (PSW) community within
the City of Toronto, and their need for a product to reduce the risk of developing musculoskeletal
disorders. PSWs, alternatively recognized as home care workers [1], provide assistance to those that need
help with day-to-day activities. PSWs provide care in a number of different settings, such as long-term
care facilities, group homes, and hospitals [2]. In particular, this RFP will focus on PSWs that work in-
home care for clients, working within the residence of the client themselves.
The risk of developing a musculoskeletal disorder poses a serious quality of life issue to PSWs as it
affects both their physical wellbeing and ability to work. This RFP will outline the mechanics behind the
development of musculoskeletal disorders in PSWs, specifically in relation to patient transfers, and why
this issue is especially prevalent in the PSW community. An examination of stakeholders will be
completed, detailing their connections to this issues and particular interests with regards to a solution. An
analysis of current products used for patient transfers will be included, discussing their advantages and
shortcomings. Finally, this information will be synthesized to provide design requirements for a potential
solution.
2Key Definitions
2.1CommunityThe American National Institute for Health defines a communityto be a group of people with diverse
characteristics who are linked by social ties, share common perspectives, and engage in joint action in
geographical locations or settings [3]. This community which this RFP focuses on is the Personal
Support Worker (PSW) community. Under the general definition, this community is defined by its social
ties (collective organizations such as the Ontario Personal Support Worker Association and the
Community Care Access Centre), common perspectives related to a shared career, and joint action with
regards to that career.
2.2Quality of LifeFor this RFP, the general definition quality of lifeis characterized within five dimensions: physical
well-being, material well-being, social well-being, emotional well-being, and development and activity
[4]. Additional attention is given to job security and its relation to income, as this can affect a persons
quality of life [5]. For the scope of this RFP, quality of life for PSWs is defined by their physical, social,
and material well-being, as it relates to the nature of their working environment (specifically by the long-
term hazards and risks posed to their physical health).
2.3Need
Needis defined by the Merriam-Webster dictionary as a physiological or psychological requirementfor the well-being of an organism [6]. Relating this definition to the PSW community and the given
definition forquality of life, we identify the need to decreasing the risk of musculoskeletal disorders
relating to patient transfer. The specifics of this need and its relation to quality of life are discussed in
Section 3.

3Problem SpecificsThis RFP focuses on the occurrence of musculoskeletal disorders amongst PSWs as a result of patient-
handling activities, specifically patient transfers. Musculoskeletal disorders (MSDs) refer to a range of
disorders of the soft tissues and their surrounding structures not resulting from an acute or instantaneous
event [3]. The need of the PSW community is to reduce the risk of MSDs occurring, in order to improve
their quality of life
3.1Relation to Quality of LifeThe development of MSDs poses a serious quality of life problem for PSWs. As previously defined,
this RFP focuses on quality of life as it relates to physical wellbeing, specifically any hazards or risks
related to the work environment. Health care workers involved in direct patient care, such nurses or
PSWs, are at a high-risk of developing MSDs [1], recording a higher-than-average rate of workdays
missed due to MSDs [4]. Such injuries directly undermine the physical wellbeing of the PSW.
3.2Factors of Occurrence of MSDsA number of different factors can be responsible for the onset of an MSD. Three primary factors
relating to patient transfers are posture, mechanical load [5]and psychosocial wellbeing [1].
3.2.1Posture
Postures at the extreme end of ones range of motion often
require muscle force to maintain the extended position.
Alternatively, non-extreme postures may still result in
abnormal gravity loading or musculoskeletal geometry,
adding stress to the system separate of the mechanical load.
Presence of these conditions in any combination increases the
likelihood of an MSD occurring [5].
3.2.2Mechanical Load
The mechanical load applied to the musculoskeletal
system is the combination of tension, pressure, friction and
irritation caused by exertion [5]. From an engineering perspective, this can be quantified as the
compression, shear, and lateral forces applied on a given section of the musculoskeletal system. One
study involving machine-assisted patient handling measured shear stresses of ~730N [6]. While this
details only one case for mechanical loading, it can be assumed that loads would be similar or greater for
patient handling with lesser degrees of mechanical aid. This creates a potential concern, as shear forces on
ligaments exceeding 1000N present a great risk of injury [7].
3.2.3Psychosocial WellbeingPsychosocial wellbeing, as it relates to MSDs, deals with the combination of a high workload, limited
control and lack of social support at work amongst PSWs and its effect on job satisfaction [1]. Higher
rates of lower back pain, a form of MSD, have been found in employees with low job satisfaction
throughout a variety of industries [8]. The perception of psychosocial work factors amongst PSW is
closely tied to the stress of patient care [1] and rates of occurrence for work-related MSD symptoms are
higher in workers that report a greater psychological stress from work [9].

abnormal musculoskeletal geometry [27]

3.3Prevalence of MSDs amongst PSWsWhile MSDs are by no means a problem unique to the PSW community, they do pose a significant
problem within the community itself. As well as being susceptible to the factors mentioned above, PSWs
are more likely to lack proper training or access to transfer assist devices (See Section 5) [14].3.3.1Presence of MSD Factors
In a comparison between PSWs and other municipal employees completed in Sweden (where PSWs
are employed by the government) found a higher rate of occurrence for MSDs within the PSW
community as compared to other jobs [9]. The same study also found that the presence of postures, loads
and psychosocial factors relating to MSD development were higher in PSWs than in other workers,
especially those relating to mechanical load and twisted postures [9]. Similar findings regarding
occurrence rates are found in the US, where occupations related to nursing rank among the highest for
days of work missed to MSDs [4].
3.3.2Training
Education for PSWs within Ontario is comprised of a two-semester college program. No registration
exam is required and likewise, no certification is provided upon completion of this program. Additionally,
there is no individual regulating body for PSWs in the workforce [2]. These requirements are very relaxed
when compared to those for a similar career, such as a Registered Practical Nurse (RPN). In Ontario,
prospective RPNs must complete a postsecondary nursing course and pass a series of nursing exams [11].
The lack of well-defined requirements for training PSWs can result in an increased likelihood of
developing an MSD. Untrained personnel performing patient-handling activities perform significantly
worse than those who have received training, when evaluated by a teaching professional [12]. The
Ontario Personal Support Worker Association has identified improper performance of these activities as a
primary source of injury [14].
3.3.3Access to Transfer Assist Devices
Within this RFP, transfer assist devices refer to any equipment, manually- or electrically-powered,
which is used to reduce the mechanical load placed on a PSW during a patient transfer [13]. Use of any of
these devices noticeably reduces the amount of stress felt by a PSW, signaling a reduction in mechanical
load. [13] The issue here is PSWs often do not have access to such devices. Even when such devices are
available, they tend to be older, less safe models. PSWs often lack the funding to purchase newer
equipment [14].
4StakeholdersDue to the nature of the need being addressed, a number of different groups can be viewed as
stakeholders. Each stakeholder group is analyzed to determine their concerns and interests regarding
potential solutions.
4.1Personal Support Workers

Personal support workers, as the primary users of any solution, are the most important stakeholders in
this project. According to a survey done by the Canadian Research Network for Care in the Community
collaborated with PSNO and OCSA [14], 26% of PSWs in Ontario reported occupational health safety
issues as a reason they would stop working as a PSW (See Figure 2). According to an interview with a
currently employed PSW working with the Carefirst Seniors and Community Association, proper
prevention of back strain can reduce discomfort felt after performing a patient transfer [19]. Helping
PSWs prevent and reduce the occurrence of MSDs is the primary objective of this design. The training
and education required for PSW qualification constitute a constraint on the design. The Ministry of Health
and Long Term Care Personal Support Worker Training Standards (1997), issued by the OCSA (Ontario
Community Support Association) in 2009 [15], outlines one possible qualification for a PSW certificate.
The lack of thoroughly defined training standards for the operation of transfer aids increases the risk of
injury. Additionally, the lack of both a unified regulatory body and reliable funding makes it difficult for
some PSWs to acquire up-to-date equipment [2] [14]. As a result, the PSWs primary concerns regarding
solutions are ease of operation, costs, and reduction of MSDs risk.
4.2
Senior ClientsAccording to a report written by OCSA in 2006 on the regulation of PSWs [16], the average age of
residents in long-term care is 82.7 years old. At the same time, 57,000 PSWs out of 90,000 PSWs in
Ontario [16] are working in long-term care sector. Seniors represent one of the largest groups PSW
clients. As the clients are the ones being transfer by the PSWs, their stake in the design of a transfer aid
must also be considered. Potential solutions must be designed with the safety of the seniors in mind.
Another concern of senior clients is the comfort level they experience during the transfer itself. This
represents a design criterion, as different types of aids can have different perceived levels of comfort [13].
Figure 2: Analysis of various factors that would persuade PSWs to quit their jobs [14]. Factors related to development of
MSDs include Lack of Ongoing Training, Occupation Health Safety Issues, and Dissatisfaction w/ Work Conditions

4.3Canadian Government (Provincial and Federal)
The Governments of Ontario and Canadas stakes relate primarily to regulations and codes. The
federal governments main concern is that any solution must adhere to the appropriate codes and
standards (See Section 6.2.1). As the level of government that deals with health care, the Ontario
Government has primary concern is how a solution might affect training standards for PSWs. One of thecurrent training standards is the 2009 revision of Ministry of Health and Long Term Care Personal
Support Worker Training Standards originally issued in 1997. The solution, if implemented throughout
the PSW community, may merit another revision of such standards. It may also be added to the existing
Long-Term Care Homes Act under Nursing and Personal Support Services Sec. 36 Transferring and
Positioning Techniques [17].
4.4ManufacturersAs the creators and implementers of any proposed solution, the manufacturers have a unique set of
concerns regarding said solutions. The manufacturers deal with the production of the solution, and as such
must adhere to the applicable standards and codes (See Section 6.2.1). The criteria that directly affect the
manufactures are the production cost, size and weight of the solution. Additionally, any material-related
requirements will impact the manufacturers stake in the solution. While such considerations are of a
lower priority than those of the PSWs and their clients, potential solutions should still consider these
factors.
4.5Hospitals and Nursing HomesIt is important to note that, while PSWs are the community on which this RFP focuses, they are not the
only group that performs patient transfers in a health care setting. While workers at hospitals and nursing
homes have more clearly defined job requirements [11], as well as access to better equipment through
increased funding, any solution that can be used by PSWs can also be used by these groups. Their
concerns regarding the solution are the same as those of the PSW. These groups are included as astakeholder due to the relation between their community and that of the PSWs.
5Reference DesignsThere are currently a number of different devices used by PSWs to aid in patient transfer. This section
outlines the most common devices available to PSWs: how they help to decrease the risk of MSDs, their
advantages and disadvantages. One additional device, the Hoyer lift, will also be examined. The Hoyer
lift is rarely used by PSWs, but is an industry standard in other medical establishments for patient
transfers.
5.1
Draw Sheets and Slider SheetsDraw sheets and slider sheets assist in the patient transfers by reducing the friction between the patient
and a surface, such as a bed. This allows the patient to slide easily across the surface without needing to
be lifted [18]. Draw and slider sheets are typically used to move patients across horizontal platforms, or to
adjust their posture while in bed [19]. Draw and slider sheets are made of low-friction fabrics or gel-filled
plastics. The primary difference between them is that draw sheets have one low-friction side, whereas
slider sheets have two [18].

The advantage of these sheets is that they are intuitive to use and easy to manufacture, while still being
effective in transferring patients. Using sheets also reduces the force required to move patients [18]. The
disadvantages of the sheets are that cannot be used to transfer patients over any gaps. Draw sheets and
slider sheets are less compatible with certain transfers, such as bed-to-wheelchair transfers [18].
Furthermore, two caregivers are required to perform a safe sheet transfer [20].
5.2Transfer BeltsThe transfer belt helps transfer patients by allowing the patient to perform assisted walking. This
involves placing the belt around thepatients waist and having the PSW hold it as the patient moves
through the transfer [21]. Transfer belts can also be used to guide patients along transfer boards. Transfer
belts come in a variety of sizes and shapes, and can be fastened with a buckle, clasp or Velcro. Thehandles may be positioned vertically, horizontally, diagonally, or in any combination of the three [21].
Padded versions are available, but while they are more comfortable for some patients, they may decrease
the caregivers feeling of control if not secured properly [18].
Transfer belts provide the PSW a secure grip in transferring the patient, while also allowing them to
work with a more comfortable posture. The downside of transfer belts deals with leveling the belt. If belt
would be too wide or narrow it could cause problems for a patient. Transfer belts do not reduce the
patients weight in any way, and are therefore not recommended for lifting patients. In fact, the use of
transfer belts may cause additional stress to certain parts of the musculoskeletal system [21]. Finally, use
of the handgrips limits a PSWs ability to respond to an emergency by limiting the use of their hands [18].
5.3Slide/Transfer BoardsA transfer board is an instrument used to bridge between two horizontal surfaces such as from a bed to
a stretcher. Smaller slide boards also exist, and are designed for seated lateral transfers. They are often
tapered at each end and can be used to bridge a gap such as when transferring between a bed and a
wheelchair [18]. Transfer boards use rollers, fabric or vinyl coverings to reduce friction across their
surface, similar to draw and slider sheets, and are often used in combination with the sheets. These boards

are suitable only for those patients who can power themselves by sliding or rolling along the board with
guidance from a knowledgeable caregiver [18].
The advantage of transfer boards is that they dont require any lifting on the part of the PSW;
moreover some patients may be able to transfer themselves. When a PSW needs to assist with such a
transfer, it takes much less force than a manual lift [18]. The problem with transfer boards is that surfaces
must be at an equal height for an easy transfer. Usage also requires the patients assistance in most cases,
making the transfer board impractical. In addition, use of the boards may still require the PSW to work
with awkward postures, increasing the risk of developing an MSD [18].
5.4Turning DiscsTurning disks are used to rotate the patient during a transfer, often used in conjunction with other
transfer devices [18]. Turning disks consist of two circular discs that rotate against each other. The inner
surfaces are made of low-friction material, while the outer surfaces are typically high-friction. Different
models of turning disk exist for pivoting seated patients or standing patients [18].
One of the advantages of the disk is that the patients feet do not need to be turned or adjusted after the
transfer. Turning disks also require minimal force to rotate or pivot patients [18]. However, most disksused in transfer are bulky, which can make them difficult to transport between clients homes. In some
cases, the disk can be difficult to control, moving too easily with light patients, while heavy patients
require excessive force to transfer [18].
5.5Hoyer LiftsThe Hoyer lift, a common brand of sling lift, is a complex tool that used for lifting and transferring the
patient with a minimum of physical effort. The Hoyer lift uses a cradle with an attached sling to maintain
the comfortable and safe position of the patient while using a moving boom and rolling base to minimize
efforts of the caregiver. There are various types of Hoyer lift, such as powered lifters or hydraulic lifters.
The sling is a modular component, with different slings available for different patients [22]. Hoyer liftshave been commonly found in medical institutions, including hospitals and nursing homes, for several
decades [13]. PSWs rarely have access to a Hoyer lift due to its high cost and need for careful assembly
and maintenance [23] [24].
Use of a Hoyer lift has been shown to reduce musculoskeletal stress noticeably when compared to
other transfer devices and unaided transfers [13]. The modular nature of the sling component allows for
customization to the needs of the patient [22]. The primary disadvantage of the Hoyer lift is its cost. As
the most expensive transfer device, PSWs can rarely afford one. It is also comparably hard to
manufacture, opposing the simple designs of the other transfer devices. Hoyer lifts are also not intuitive to
use, requiring a precise understanding of how to operate them safely [22] [24].
6Design RequirementsThis section outlines the design objectives, constraints and criteria to which any proposed solution for
this RFP should adhere. These requirements will help create a design space.

To: Kirsten Ballantyne: 2013-01-29
Hello Ms. Ballantyne,
I'm a first year student at the University of Toronto's Faculty of Applied Science and
Engineering. I'm currently studying Engineering Science, and one of my projects this term looks
at identifying a community within the City of Toronto, and designing a Request for Proposal
around one of that community's needs. My team has chosen personal support workers as the
community we would like to focus on. Is there anyone at the OPSWA, either you or someone
else, that I could talk to to better understand the needs of personal support workers?
Thank you for your time
From: Kirsten Ballantyne: 2013-01-29
Good day,
You certainly can ask questions. Please ask away. Many, I'm sure, questions you have could
also be answered from out website.Www.opswa.com
Looking forward to your questions,
Kirsten,
OPSWA communications liaison
To: 2013-01-30
Hello again,
Thank you for your time. I looked through the articles on available on the OPSWA website,
and they definitely did help to answer some of my question. To that end, I have two questions I
like to ask you.
First off, are there any aspects of a personal support worker's job where the current protocols
(available technology and common practices) could be improved? One of the goals of this project
is improving quality of life within the chosen community, so if you can think of any facets of
being a personal support worker that could be improved in such a respect would be appreciated.
Secondly, referring specifically to the article about transfers and assistive devices, how present
is the risk of back injury when it comes to performing transfers? Additionally, how well do the
current practices and assistive devices prevent back injuries from occuring?
Thanks again for your time.

From: 2013-01-30
Good evening,
The protocols and technologies in place can certainly be improved. Many company's are
coming up to date and using computerized documentation programs and also telephone call-
in systems for signing in and out of clients homes (home care) and or for messaging systems. All
institutions/facilities/residences would very much benefit from up to date technology if they have
not yet implemented it. Equipment PSWs use is a rough subject. New facilities usually carry all
brand new equipment. But private run facilities and or home care may not have up to date(older)
or safe equipment. Or they may not have enough equipment. Due to funding or personal finances.
The PSW role was a grey area in the health care field. Now it is becoming much more black and
white but PSWs desperately need a governing body so all standards and practices are universal.
That is the goal. It protects, most importantly, the patients/clients and as well as the PSWs.
As for back injuries, many injuries of all kinds happen because of unsafe equipment or
improper use. Education is a must! Learning how to safety assist transfers and how to safety usethe transferring devices is so important. Body mechanics! Even a brand new piece of equipment
can result in injury if a PSW does not use proper body mechanics. Knowing the equipment they
are using is also important. PSWs are not to use any new equipment or use any old equipment
unless they properly know how to. A supervisor or trainer is to sign off that the PSW can use it
safety and correctly. From that point on the PSW is able to provide care with those devices
themselves, unless... it is a lift or other device that requires 2 PSWs to use safely. Its called a "2
person transfer".
I hope I managed to answer your questions?

Good morning,
Thank you once again. Using the information given in your answers, my group has been able
to begin framing our RFP. If it isn't too much trouble I do have one follow-up question. Most
importantly, is there an average price range for the equipment that PSWs use? And if so, what is
it? If it's different for different types of equipment, I'd be interested in knowing all the various
ranges.
Thanks again for your time,
From: 2013-01-31

Good morning,
I personally do not know the price ranges for the equipment used. I'm assuming since there are
so many transfer devices, from hand held to mechanical, that the price range is very wide. Certain
medical and home care medical shops do specialize in supplying some of these. If you google it I
am sure you will find some information.
I'm glad I could help,

Appendix BSummary of Interview: Winnie Zhang
What do your services cover?
Cleaning, Feeding, Reminding clients for taking medicine, helping client before and after shower..etc
Are lifting and moving the major action while you are working?
Yes, lot of the seniors are disabled to some extent, most of them require walker or cane and some of them
are completely disable, so while feeding, moving them to shower, a lot of lifting, holding are required.
The other primary source of lifting and moving is cleaning.
How often do you feel discomfort in your muscle?
It is hard to say, it sort of builds up over time. However, I do use some sort of thermotherapy such as heat
bag to help relaxing my muscle.
What kind of negative impacts on your spare time brought by musculoskeletal discomfort?
It brings physical discomfort such as muscle ache at a certain posture and feeling of tiredness. It often
ruins the mood during rest too.
Remaining details are omitted due to its insignificance in the discussion

The test is then performed with the surface horizontal and with 1,5 times maximum load (3.24) for 20min.
5.3 Requirements for static stability
During the static stability test according to 5.4, both unloaded and loaded with the maximum load (3.24),the hoist shall not lose its equilibrium (balance) at the following angles:
a) forward and backward directions 10 with the chassis in the intended travelling position;b) forward and backward directions 7 with the chassis in the most adverse condition;c) any other direction, 5.
5.4 Test methods for static stability
a) The tests shall be carried out in the forward and backward travelling directions and
with the chassis in the travelling position as indicated by the manufacturer and with theload placed in the most adverse position.b) The tests shall be carried out in the forward and backward directions and in the mostadverse direction. If there is more than one intended direction of travel (forwards) theyshall all be regarded as forwards.c) The tests shall be carried out with the hoist in its most adverse position regarding theposition of the wheels, CSP, base and brakes.
UnloadedPosition the unloaded hoist on the test surface with the wheels towards the stop(s). Incline the testplane gradually until the hoist loses its equilibrium (balance). Record the angle of inclination.Repeat the test in the backward and sideways directions.
LoadedAttach the maximum load to the hoist's CSP in such a way that the load is able to move freely.Repeat the procedure as for the unloaded hoist. For hoists with rigid patient supports the centre ofgravity of the load shall be placed in relation to the back rest according to figure 2, but not morethan 350 mm from the front edge of the seat.
