Frail Elderly: The Physiotherapist's Role in Preventing Hospital Admission

Frailty[edit | edit source]

Frailty is a clinical state that is associated with an increased risk of falls, harm events, institutionalisation, care needs and disability/death.[1]The physiotherapist should be aware of the risk factors for frailty. If frailty is suspected, referral to other professionals may be required. Frailty and disability do not always co-exist, however they can be linked. In some cases, frailty may be a consequence of disability and in others, the causation of disability[2]

Frailty associations[3]

It is important to note that although frailty is age-related, it is not an inevitability[4]. In those aged 65 to 85, there is thought to be a 10% incidence of frailty. However, this figure increases to 25 to 50% in those aged 85 and over[5].

Ageing Population[edit | edit source]

People worldwide are living longer, with most people expected to live into their sixties and beyond. Every country in the world is experiencing growth in both the size and the proportion of older persons in the population. Older age may involve complex health states, commonly called geriatric syndromes, often the consequence of multiple underlying factors and include frailty, urinary incontinence, falls, delirium and pressure ulcers. So today with the growing older populations, healthcare services are required to transform to better meet the population’s needs[6][7].

Costs[edit | edit source]

Health care costs already account for between 8% and 10% of GDP in developed countries. It is anticipated that even a modest increase in health care costs would generate significant pressure on the economy. For this reason every developed country is attempting to reform its health care system.[8]

The length of time frail people stay in hospital differs throughout the world. The UK is 16th shortest in the world when it comes to the average length of stay in hospital[9]. However, admittance to hospital and the cost implications of long term hospital stays are similar worldwide to the UK[10][11].

Relevance To Physiotherapy[edit | edit source]

With life expectancy continuing to rise globally there is an increasing public health focus on the maintenance of physical independence among all older adults. Identifying interventions that improve physical outcomes in pre-frail and frail older adults is imperative.[12]

Introduction to the Physiotherapist's Role[edit | edit source]

The nature of the physiotherapy profession is to help restore movement and function in someone affected by illness or injury[13]. Physiotherapist’s are expanding their service now to deliver interventions to several different settings; for example, within day hospitals, in the patient’s home and in community clinics.

  • It has been suggested that physiotherapists could be stationed within hospital A&E departments to undertake frailty and falls risk screening and make rapid decisions on whether the patient can safely return to their pre-admission destination[14][15].
  • The comprehensive geriatric assessment (an iterative collaborative multidimensional framework and process of assessment used to assess people living with frailty) may involve the physiotherapists. Their involvement in the delivery of a CGA is varied and ultimately depends on their speciality, which setting they work in, and the reasons for the patient being referred. If there has been a problem identified that can be able to acted upon it should be, if not a referral to an appropriate clinician is recommended[16].
  • A randomized control trial[17] suggests home-based exercise and nutrition strategies have a positive outcome on the frailty score and physical perform 

Physiotherapy Treatment[edit | edit source]

There are several clinical guidelines available for healthcare professionals to assist them in preventing hospital admissions providing quality care for patients. However, whilst they recommend physiotherapy intervention, these guidelines lack rigorous information and evidence surrounding treatment [18]

Injuries leading to hospitalisation are more common in people over 65 and they can be more critical and more often preventable. [19] Falls represent the most frequent and serious type of accident in people aged 65 and over in the UK [20]. As falls risk increases with age, it is important for the physiotherapist to identify those at risk early, recognise and modify risk factors and provide timely intervention to prevent falls and subsequent injury[21].

Treating falls and fall related injuries:[edit | edit source]

Below are examples of treatment options follows, although this list is not exhaustive.

Resistance Training[edit | edit source]

Weights.png

A significant component of age-related weakness and frailty is sarcopenia. Sarcopenia increases the risk of frailty and falls and in turn, hospitalization in the older adult population[22]. Resistance training has been suggested as a potential treatment for sarcopenia and its prevention. Resistance training is designed to improve muscular fitness by exercising a muscle or a muscle group against resistance[23]. This could lead to improved function, increased quality of life and reduced likelihood for falls[24]. Resistance training programmes have consistently shown to improve muscle strength and mass in older adults[25][26], however, it is questionable whether this transfers to reducing the risk of falling.

Latham and colleagues[27] have conducted the only trial which has studied the effect of seated resistance training on risk of falls in an older adult population. It was found to have no effect on falls rate or risk of falling and an increased chance of musculoskeletal injury. As a result, seated resistance training or high intensity resistance are not recommended. Furthermore, Liu-Ambrose and colleagues[28] examined the effect of a twice weekly course of 50-minute resistance training sessions on number of falls and risk of falls in a female population aged 75-85. Exercises included targeted upper limb, trunk and lower limb muscles and again, resistance training alone was found to have no significant effect on number of falls or risk of falls. However, when combined with agility training, participants did develop a decreased risk of falling. It has been proposed that strength training alone is not enough to fully manage falls risk, however, it should be part of a multi-component falls prevention exercise programme[29]. We will discuss this in further detail later on in the learning resource. 

Balance Re-education[edit | edit source]

Balance disorders are very common in frail older adults and are a key cause of falls in this population. They are associated with reduced level of function, as well as an increased risk of disease and death. Most balance disorders comprise of several contributing factors including long-term conditions and medication side effects[30]. Recent research conducted examined the effectiveness of two-year progressive balance retraining in reducing injurious falls among community-dwelling women aged 75-85[31]. The study took place over 20 centres and recruited 706 participants, who were randomised in to the intervention group, who received weekly dynamic balance exercise supplemented by prescribed home exercise, or the control group, who did not take part in the exercise. Over the two-year intervention period, the injurious fall rate was 19% lower in the intervention group than in the control group highlighting the benefit of a balance training programme.

Enjoying the wii.png

Exergaming is a relatively new treatment concept and is thought to increase motivation and enjoyment for users.
The Nintendo Wii has a built in pressure sensor that allows for feedback to be delivered to the user on their performance. There is evidence that a Wii based balance exercise programme could improve balance ability in the frail elderly population[32], so as a result, Fu and colleagues[33] conducted research into whether this would transfer to reducing fall risk and incidence.


Sixty participants aged 65 or over received balance training three times per week for six weeks. They were randomly allocated into the intervention group who undertook balance activity on the Wii, or the control group who received conventional exercise. The results showed that while both groups reduced their risk and incidence of falls, the intervention group showed a more significant improvement.

The Wii balance training has shown to reduce falls by 69% compared with conventional training. Additionally, the intervention group had a 35% improvement in the fall risk score, considerably greater than that of the conventional balance training at 11%. As a result, the use of the Nintendo Wii for balance re-education is highly recommended and perhaps this suggests the need for further research on various other computer games available.

Tai Chi[edit | edit source]

Tai chi is a newly emerging exercise incorporating breathing, relaxation and slow and gentle movements with strengthening and balance exercises. Whilst originally an ancient 13th century Chinese martial art, it has recently become more prevalent around the world as a health-promoting exercise[34]. Whilst there is room for more rigorous research on the health benefits of tai chi, it is thought that it could help adults aged 65 and over in improving balance[35], reducing stress[36] and controlling osteoarthritis pain[37]. Additionally, in a high quality systematic review, tai chi was not only found to significantly reduce rate of falls, but also lessen risk of falls[38]. As tai chi is considered a low impact exercise, it is suitable for most to participate in and should be considered as a treatment option.

Otago Exercise Programme[edit | edit source]

The Otago Exercise Programme (OEP) is an evidenced-based, "home-based, individually tailored strength and balance retraining programme”[39]. The OEP is carried out by physiotherapists (and/or trained providers such as community nurses). It is designed to be carried out over 12 months (or more recently, six months). The physiotherapist makes approximately five home visits within that period and also makes monthly phone calls to the participant to encourage adherence[40].

Backward-chaining[edit | edit source]

Declining muscle function in older adults reduces their ability to rise from the floor following a fall and up to a half of all non-injured fallers are unable to get up[41]. When someone is unable to get up off the floor unassisted, the associated risks are far greater due to the complications that can occur from lying on the floor for an extended period of time – for example, dehydration, hypothermia, pneumonia, pressure sores, unavoidable incontinence and even death[42]. This inability to get up has a poor prognosis in terms of hospitalisation and mortality[42], thus, a long lie is one of the most serious consequences of a fall. The responsibility of the physiotherapist is to ensure the patient has a plan should they fall and are unable to rise and educate them about available strategies to combat this[43].

Backward-chaining is a method utilised to re-educate patients in rising from the floor unassisted. It consists of a sequence of movements combined together to help teach someone to be able to get down to the floor safely. Once learnt, the sequence is reversed and is applied to teach a safe and effective way to get up from the floor. The movement is broken into several stages depending on the patient’s ability. The patient will complete one stage, then return to a stand. Then they will add on the next stage and return to a stand. This is repeated until the patient is able to stand from lying on the floor.

The effect of backward-chaining on an individual’s ability to rise unassisted from the ground has been proven to be beneficial. In the only study to compare backward chaining with a control of conventional therapy, it was found that the backward-chaining method significantly enhances ability in rising after an incidental fall (20-40%)[45]. The control group showed no improvement. The study took part over 12 weeks and included 120 participants aged 80-99. Additionally, Timed Up and Go and Tinetti measurements were also compared before and after the intervention and control and a notable improvement was only observed from the intervention group. This highlights the benefits for improving functional capabilities in addition to rising abilities.

Fear of Falling[edit | edit source]

The prevalence of fear of falling in community-dwelling older adults ranges between 12% and 65%[46]. Whilst it frequently occurs after falls[47], it is also established in those without a fall history[48]. It can lead to a loss of independence, activity restriction and ultimately a poorer quality of life[49]. Not all will avoid ADLs due to fear but for those who do, it can have debilitating and devastating effects[50]. Lethem et al[51] introduced the psychiatric concept of a fear avoidance model and is it is commonly utilised in the prevention of acute musculoskeletal pain becoming chronic[52]. However, the hypothesis behind the model can be adapted to explain fear of falling and avoidance of activity. Extreme avoidance can lead to a decline in physical function, and ultimately an increased risk of falls, further fuelling fear and avoidance of activities. This is illustrated in the below fear avoidance model, adapted from Lethem et al[51].

Adapted fear avoidance model[51]
Fear avoidance model (Falls).PNG

The physiotherapist is in an ideal position to steer the individual towards the route of confrontation and recovery as opposed to activity avoidance and disability[21]. There is high quality evidence from two systematic reviews highlighting the benefits of treatment to improve confidence and reduce fear of falling[53][54]. Recommended interventions include: exercise, including tai chi, and multi-component falls prevention programmes.

Multi-Component Falls Prevention Programmes[edit | edit source]

Falls class.png


As most falls are multifactorial in origin, they usually require several interventions[55]. Such interventions typically involve a combination of medication review and optimisation and education, environmental modification and exercise. This type of programme would be delivered by a multidisciplinary team in which the physiotherapist would be a key member. A Cochrane systematic review suggests that the physiotherapy treatment should combine all elements mentioned above; that is strengthening, balance, backward chaining, tai chi and confidence building with education, tailored to each individual. Clinic-based group exercise or individual exercise in the home setting is suitable. However, further research is needed into the effectiveness of medication management in preventing falls[38].

Additionally, in a systematic review, it was reported that for the greatest effect, exercise programmes should include a high level challenge to balance, alongside strength and walking training[29]. However, brisk walking training should not be prescribed to those at a high risk of falls. Furthermore, it was found that exercise should not only target those at high risk but also the general community and it should be performed for at least two hours per week on an ongoing basis.

Self-Management[edit | edit source]

Selfmanagement NHS.jpg

For many people, older age is associated with long term conditions such as heart failure, dementia, chronic obstructive pulmonary disease (COPD) and diabetes. As we know, an element of frailty is the decreased ability to withstand illness. Exacerbation of chronic conditions, an acute illness or a combination of both can trigger acute disability in frail older people and cause hospitalisation or institutionalisation[56]. Emergency hospital admissions is a major concern for the NHS. There are a number of factors associated with increased rates of admission including area of residency, ethnicity, socio-economic deprivation and environmental factors. Older people are also identified as being at a higher risk of hospital admittance[57].

In Scotland, 40% of the population have at least one long term condition (LTC). People with LTCs and co-morbidities are known to have poorer clinical outcomes, poorer quality of life and longer hospital stays[58]. The Scottish Government[59] reports that people with LTCs are twice as likely to be admitted to hospital. The ageing population and the increased prevalence of LTCs requires healthcare professionals to move their focus towards preventative strategies and empowering self-management[60].

Physiotherapist's have a role in promoting self-management of long term conditions and physical activity. Disease-related self-management abilities such as taking medication and exercise are often promoted by health care professionals. However, there may also be a need for interventions aimed at self-management of overall health and well-being to contribute to healthy ageing[61]. Older peoples’ abilities to self-manage the effects of the ageing process depends on physical, psychological and social aspects of their life[62]. Physiotherapists working with frail older people could play a role in promoting healthy ageing. Evidence shows that interventions to promote healthy ageing can be used to the delay the onset of frailty and reduce its adverse outcomes among older people[62].

As older people often have co-morbidities leading to a mixture of physical and psychosocial issues, self-management interventions should focus on providing them with general behavioural and cognitive skills for dealing with range of problems, rather than focusing on health-related problems only[61]. It is outwith the scope of this learning resource to go into detail about how to promote self-management strategies as you are likely to see a range of diverse patients presenting with multiple conditions and challenging psychosocial issues. Your treatment plan will depend on the patient's presenting condition. However, as physiotherapists, we believe our main role within self-management can be to promote physical activity to contribute to the healthy ageing process.

Physical Activity[edit | edit source]

Functional capacity declines with age and this is further accelerated by low levels of physical activity.
The recommendations for physical activity for older adults (65+)[63]:

  • Older adults should aim to be active daily
  • At least 150 minutes a week of moderate intensity activity
  • Muscle strength training twice a week in addition to the 150 minutes of activity
  • Balance training and co-ordination should be incorporated into activities to manage risk of falls
  • Minimise sedentary time 

Physical activity significantly decreases with age. The graph below shows the percentage of men and women meeting the physical activity recommendations in Scotland[64].

Benefits of Physical Activity in Frail Older Adults[edit | edit source]

Strength, endurance, balance and bone density is lost at a rate of 10% per decade, while muscle power reduces at around 30% per decade[65]. Sarcopenia is highly prevalent among older adults and has been identified as a risk factor for frailty[66]. Being physically active slows down these physiological changes associated with ageing. Physical activity can also reduce the risk of falls, promote cognitive health and self-management of chronic diseases. It can also slow down the deterioration in ability to perform ADLs and maintain quality of life in older adults[67][68]. A meta-analysis[67] found that exercise is beneficial to improve balance, gait speed and abilities to carry out ADLs in the frail older adult population. 

Factors Influencing Participation in Physical Activity in Older Adults[edit | edit source]

Older peoples’ participation in physical activity can be effected by biological, demographic, physiological and social factors. These factors are important to be aware of when attempting to motivate older people to increase their activity levels.[69]

  • Men are more active than women
  • A decline in physical activity with age is higher among: minority ethnic groups, those from lower socio-economic backgrounds, those with lower education and those living alone
  • Older people might be less able due to pain, reduced mobility and the need of assistance to mobilise[68]
  • Physical activity can be influenced by trusted others such as health care professionals, care givers, family and friends
  • Lack of transport often affects older people's abilities to part take in activity

Physiotherapists Role in Promoting Physical Activity in Frail Older Adults[edit | edit source]

Due to their training and experience, physiotherapists are in a good position to promote health and well-being of individuals and the community through education on physical activity and exercise prescription[70]. Recently there has been a shift in the general public's health agenda towards the prevention of chronic conditions and enabling the ageing population to stay active and manage conditions in the community. This has required a change in the role of the physiotherapist towards addressing these issues through promotion of physical activity and other lifestyle changes[71]. When encouraging physical activity, physiotherapists should also aim to[72]:

  • Identify fears and barriers to being physically active and provide solutions to overcome these
  • Provide ongoing support and encouragement

Exercises for Frail Older Adults[edit | edit source]

These are the recommended activities and intensity for frail older adults to increase physical activity. These aim to improve general health and well being, as well as reduce the risk of falls and manage chronic lifestyle conditions:

  • Sessions as short as 10 minutes can provide health benefits[65]
  • Frail older adults should aim to accumulate numerous 10 minute sessions to achieve the recommended activity guides[73]

Suggested activities:

  • Take the stairs[63]
  • Walking[63]
  • Do housework or gardening[63]
  • Tai Chi[73]
  • Dance[73]
  • Swimming[63]
  • Home-based or group exercise classes[65]
  • Breaking up time spent sitting with short regular periods of standing or walking[73]
  • Encourage to move for longer. E.g. Going from moving 5 minutes to 10 minutes may increase the intensity[73]

A Systematic Review of Randomized Controlled Trials[74] suggested that a low dose of creatine monohydrate along with resisted exercises may improve upper and lower extremities strength in healthy older adults.

Motivation[edit | edit source]

Maslow.png

Motivation can be defined as the processes that explain an individual’s intensity, direction and persistence of effort towards
achieving a goal. Motivation often stems from a need we must fulfil and this leads to a specific behaviour[75]. In 1943, Maslow developed a theory of human motivation aiming to explain and rank all types of human needs[76]. Maslow’s Hierarchy model is made up of five levels ranked in importance with the most basic needs at the bottom. In order to progress up the hierarchy, the lower needs must be fulfilled.


Depending on your preferred ways of learning, choose if you want to read or watch the video below to learn more about the Maslow’s Hierarchy.

[77] 

There are many factors that motivate the elderly to participate in exercise programs, see below[68].

Motivating Factors.PNG

It is important to note that studies have found a correlation between those with a previously active lifestyle and those who were more likely to perform exercise programs[68] supports this idea of goal setting within the elderly population. Without goals, adherence to exercise is limited. The literature again reinforces the fundamentals of effective goal setting:

  • Patient-centred goals
  • Small goals incrementally increasing to large goals e.g. short term and long term
  • Should adhere to SMART principles

Despite the need to motivate it is also important to listen to the patient and their needs. One of the ways we can encourage motivation is by arranging a group exercise class, as this not only promotes the physical benefits of exercise, but allows participation in a social gathering[78]. Furthermore, research suggests that people are more likely to exercise if they have a companion[79].

Conclusion[edit | edit source]

The average age of the population is increasing and it is suggested that the prevalence of frailty will multiply[80]. Subsequently, there has been a shift of care from reactive to preventative strategies and a focus on providing early interventions to reduce costly unplanned admissions to hospital[81]. Several guidelines are available, but none specifically detail the physiotherapist's role.
