What is frailty?
- Frailty is a clinically recognised state of increased vulnerability. It results from ageing associated with a decline in the body's physical and psychological reserves
- Frailty varies in its severity and individuals should not be labelled as being frail or not frail but simply that they have frailty. The degree of frailty of an individual is not static; it naturally varies over time and can be made better and worse
- Frailty is not an inevitable part of ageing; it is a long-term condition like diabetes or Alzheimer's disease
Why is frailty important?
- Many people with multiple long-term conditions will also have frailty, which may be overlooked if the focus is on disease-based long-term conditions such as diabetes or heart failure
When and how should frailty be recognised?
- Any interaction between an older person and a health or social-care professional should include an assessment which helps to identify if the individual has frailty
- The type of assessment will differ depending on circumstances. But planning any intervention, such as new medication, emergency admission, or elective joint surgery, in an individual who has frailty without recognising it, risks significant harm to the patient as the presence of frailty may change the balance of benefit and risk
- The presence of one or more of these five syndromes should raise suspicions that the individual has frailty and that the apparently simple presentation may mask more serious underlying disease:
- falls (e.g. 'collapse', 'legs gave way', 'found lying on floor')
- immobility (e.g. sudden change in mobility, 'gone off legs', 'stuck on toilet')
- delirium (e.g. acute confusion, worsening of pre-existing confusion/short term memory loss)
- incontinence (e.g. new onset or worsening of urinary or faecal incontinence)
- susceptibility to side effects of medication (e.g. confusion with codeine, hypotension with antidepressants)
Simple assessments for identifying frailty
- A range of simple tests for identifying frailty is available:
- gait speed: taking more than 5 seconds to cover 4 metres
- 'timed up-and-go test' (TUGT): a cut off score of 10 seconds to get up from a chair, walk 3 meters, turn round and sit down
- A brief clinical assessment would help exclude some false positives (e.g. fit older people with isolated knee arthritis causing slow gait speed)
- PRISMA 7 Questionnaire —an alternative for self-completion, including use as a postal questionnaire. A cut off score of 3 or more suggests the need for further clinical review (see Box 1)

How should frailty be managed?
- Assess clinical condition—measure vital signs and consider if any 'red flags' are present which suggest the patient needs acute hospital care, such as hypoxia, significant tachycardia, or hypotension (if possible compare readings with what is usual for that patient as recorded in their care and support plan (CSP))
- Assess current function—can they get out of bed, can they walk, are they able to use the toilet?
- Are they confused—is this usual (may need input from carers to determine this) or worse than usual? Patients with dementia are at higher risk of delirium. Is there evidence of head injury?
- If the patient is stable, i.e. demonstrates usual level of function, but has a temperature or evidence of delirium, they will need timely medical review, but not necessarily immediate conveyance to hospital
- If a patient is not severely unwell but is unable to maintain their usual status quo in the community due to a change in their care needs, it is good practice to transfer care to a responsive community service rather than arranging admission to hospital, as long as a diagnosis has been made
Summary of BGS recommendations
- Older people should be assessed for the presence of frailty during all encounters with health and social-care professionals. Gait speed, the TUGT and the PRISMA questionnaire are recommended assessments
- Provide training in frailty recognition to all health and social-care staff
- Do not offer routine population screening for frailty
- Look for a cause if an older person with frailty shows decline in their function
- Carry out a comprehensive review of medical, functional, psychological, and social needs based on the principles of comprehensive geriatric assessment (CGA)
- Ensure that reversible medical conditions are considered and addressed
- Consider referral to geriatric medicine where frailty is associated with significant complexity, diagnostic uncertainty, or challenging symptom control
- Consider referral to old age psychiatry for those people with frailty and complex co-existing psychiatric problems, including challenging behaviour in dementia
- Conduct evidence-based medication reviews for older people with frailty (e.g. STOPP START criteria; see Box 2)
- Use clinical judgment and personalised goals when deciding how to apply disease-based clinical guidelines to the management of older people with frailty
- Generate a personalised shared CSP outlining treatment goals, management plans, and plans for urgent care. In some cases it may be appropriate to include an end-of-life care plan
- Where an older person has been identified as having frailty, establish systems to share health record information (including the CSP) between primary care, emergency services, secondary care, and social services
- Develop local protocols and pathways of care for older people with frailty, taking into account the common acute presentations of falls, delirium, and sudden immobility. Wherever the patient is managed, there must be adequate diagnostic facilities to determine the cause of the change in function. Ensure that the pathways build in a timely response to urgent need
- Recognise that many older people with frailty in crisis will manage better in the home environment but only with appropriate support systems
