Dementia is a syndrome due to disease of the brain, usually of a chronic or progressive nature, in which there is a disturbance of multiple higher cortical functions, including memory, thinking, orientation, comprehension, calculation, learning capacity, and judgment(1).
Physiotherapy is clinically and cost effectiveSize of the problem
- 750, 000 people in the UK live with dementia. Two thirds live in their own homes & one-third in care homes(2)
- By 2039 there will be 1.4 million people with dementia in the UK, with costs trebling to over £50 billion per year(2)
- Dementia contributed to 11% of years lived with disability among people aged 60 and over; more than stroke (9.5%), musculoskeletal disorders (8.9%), cardiovascular disease (5.0%) and all cancers (2.4%)(8)
- Up to one in four hospital beds at any one time is occupied by a person over the age of 65 who has dementia(9)
Physiotherapists are key in delivering the National Dementia Strategy UK wide(2, 3, 4). The priority strategy objectives are:
Good quality early diagnosis and intervention for all
Physiotherapists, as autonomous practitioners, can undertake detailed, individually tailored assessments of the impairments, activity restrictions and participatory limitations faced by people with dementia.
Physiotherapists work as part of a multi-disciplinary team ensuring the delivery of high quality, effective care, in line with the The NICE Quality Standard(5) for people with dementia.
This standard advocates provision of assessment and ongoing personalised care plans, addressing individual needs.
NICE(5) and SIGN(6) guidelines recommend physiotherapy for promoting and maintaining independence for this client group.
Implementing the Carers’ Strategy
Carers of people with dementia often display poor health when compared to their age-matched peers(7).
Physiotherapy can assist in reducing the burden of care by educating carers to encourage independence in people with dementia.
Improved quality of care for people with dementia in general hospitals
Physiotherapy services for people with dementia have been identified as key in contributing to a cost saving of £6 million a year(10).
Physiotherapists contribute to multi-disciplinary team discharge planning. Early discharge planning is a key component of reducing length of stay for patients with dementia(9). The average hospital stay for a common hip fracture is seven days.
However, over 85% of dementia patients with this injury stay for up to 14 days, and 34% for over a month; the extra cost is estimated as £5, 950 per patient(9). Falls are the most common reason for hospital admissions, and account for 14% of all admissions for people with dementia.
Poor balance, known to increase the risk of falls, can be improved by physiotherapy-led exercise(11). Exercise can have a significant and positive impact on behavioural and psychological symptoms of dementia(12), improving cognitive function and mood, which can reduce the need for pharmacological intervention(13).
Living well with dementia in care homes
Cost of dementia
Dementia costs the UK economy £20 billion a year(17).
The costs per person are higher than for all other mental health conditions(18).
The annual costs per person with dementia living within the community are estimated as:
- £16, 700 for people with mild dementia
- £37, 500 for people with severe dementia
- £31, 300 for people in care homes(8)
Physiotherapy plays an essential part in promoting and maintaining mobility for people with dementia(14), and particularly has a vital role in end of life care, by managing positioning, seating and painful contractures.
People with dementia often have difficulty expressing pain. Pain affects cognition, motivation and response to any intervention; physiotherapists are experts in identifying and treating pain(15) and provide essential support and education to care home staff and carers.
An informed and effective workforce for people with dementia; There is evidence to show that physiotherapy interventions reduce the risk of developing dementia(19) and promote a delay in the progression of both cognitive and functional decline(11).
The majority of people with dementia are elderly and often have comorbidities(15). Physiotherapy-led exercise that increases physical activity levels can also reduce cardiovascular risk factors, as well as the risk of other chronic conditions, such as diabetes and osteoporosis.
Greenview Intermediate Care Unit, a multiagency project commissioned by NHS Harrow, offers rehabilitation to people with dementia and delirium, giving them the best opportunity to return home.
Patients are provided with physiotherapy five days a week following an assessment and home visits are conducted to assess risk factors prior to discharge.
With 58% of patients returning home, physiotherapists carry out follow up home visits to evaluate progress, and liaise with other multidisciplinary agencies to ensure patients remain safe at home.
The service has reduced inpatient hospital bed stay, prevented future hospital admissions and reduced costs(2, 16).
Physiotherapy, in particular physiotherapy-led exercise, is a clinically and cost effective, accessible intervention. It preserves and promotes activity for people with dementia.
Physiotherapy interventions improve the quality of life for those with dementia and reduce the burden of care.
