Key learning points
- Older people should be routinely asked about falls when they come into contact with a nurse
- Older people who have fallen, or are at risk of falling, should be offered a multifactorial falls assessment and an individualised intervention
- Strength and balance exercise is one of the most important falls prevention strategies and should be offered to everyone who has fallen or is at risk of falling
Falls are hugely common in the older population, affecting one in three people over the age of 65 years and half of those aged over 80 years.1 Unfortunately, one quarter of these will suffer a serious injury requiring hospitalisation, but even a single non-injurious fall can increase the likelihood of long-term care, activity restriction, fear of falling, lack of confidence and social isolation.2 Fortunately, falls and falls-related injuries can be prevented, even by simple measures.
NICE has both a clinical guideline (updated in 2013) and a quality standard (updated 2017) for falls in older people.3 A summary of the key points in these documents is provided in table 1.

Identifying older people at risk of falls
The single greatest risk factor for falling is a previous fall in the past 12 months.4 For this reason, all older people who either report a fall, or present with a fall, should be offered an assessment and intervention. However, as 30% of older people who have fallen in the last three months are unable to recall it, relying on patient-reported falls will miss a large proportion of high-risk individuals.5 Some older people are afraid to admit that they have fallen. This may be out of a fear of appearing frail or of being moved into a residential home.
Primary prevention, using the primary care record to identify people as high risk and offering them an assessment and intervention, does not reduce falls and is not cost effective.6,7 However, both NICE and the joint British and American Geriatrics Societies recommend that older people are routinely asked about falls or mobility problems to identify those most at risk.8 There are risk assessment tools available,9,10 but many require equipment, space and time. It may be more practical to simply observe patients walking in their home, or between the waiting room and the consultation room. If there is a gait or balance abnormality, or if the patient reports subjective abnormalities, they should be offered a falls assessment.
The multifactorial assessment
The principle components of the falls assessment are in table 1 above. There are few recommendations on how to specifically assess each of these, so the tools that are most appropriate to your population and service should be used. A detailed falls history is useful to identify specific problems, such as dizziness, home hazards or balance problems.
The multifactorial intervention
Strength and balance training
Exercise is one of the most important interventions and should be offered to everyone at risk of falls. However, not all forms of exercise are effective at reducing falls. For example, walking is not sufficient to prevent falls and Tai Chi is only effective for those who are at low risk.11 The most effective form of exercise is multi-component, addressing both strength and balance.
The most commonly used regimes are the Otago and the FAME programmes.12 They can be delivered in an individual’s home, or in
a group setting.
Ideally these should be assessed by an occupational therapist (OT), as there is evidence to show that this is more effective than a non-OT intervention.13 However, there are simple steps that can be recommended to all older people:
- Remove or tape down rug edges.
- Clear clutter from walkways and stairs.
- Ensure adequate lighting throughout the home.
- Position cables out of harm’s way.
- Remove door thresholds or make them more visible.
- Wear a pendant/watch alarm, or carry a mobile phone.
- Wear sensible footwear and maintain foot health.
Encourage older people to visit their optician every year and report falls to their optometrist. In general it is recommended that people do not use bi- or varifocal lenses if they are at risk of falls. Offer advice on how to keep eyes healthy, such as avoiding smoking, protecting eyes from the sun, eating brightly coloured fruit and vegetables, controlling diabetes and hypertension.
There is a lack of evidence on medications that should be stopped to prevent falls. In general, it is psychiatric medications that are most associated with falling. These include sedatives, antipsychotics and antidepressants.15 As with all medication decisions a risk/benefit discussion must be had with the individual.16 Cardiovascular medications, such as antihypertensives, are associated with falls, but there is no evidence that stopping them will reduce falls.
Falls are the most common reason that people with atrial fibrillation are not offered anticoagulation medication.17 However, one study found that an individual would need to fall 295 times per year for the risk of haemorrhage to outweigh the benefit of stroke prevention.18 Discuss the risks and benefits with the patient.
Bisphosphonates may be considered for those at risk of fracture. NICE recommends assessing the risk of fracture in all people with a history of falls using FRAX or QFracture.19
Underlying medical disorders
A 12-lead ECG and a lying and standing blood pressure should be checked as part of a multifactorial falls assessment. Cardiovascular disorders such as orthostatic hypotension, arrhythmias, carotid sinus syndrome and vasovagal syncope can all present as falls rather than as syncope in older people. When this is the case, individuals tend to experience dizziness, describe falling for no obvious reason or suffer facial and head injuries. These causes should also be considered for unexplained falls, or recurrent injurious falls. History and examination may reveal signs of other underlying medical conditions such as Parkinson’s disease, multiple sclerosis, arthritis and strokes. Referral to specialists is required for these.
NICE recommends that a falls assessment be performed by a person with appropriate experience, ideally in a specialist service. An assessment should be a multidisciplinary process. Nurses in primary care are ideally placed to spot patients in need of such an assessment and begin the conversation with them.
