LEARNING OBJECTIVES

  • At the conclusion of this article you will be able to:
  • Outline the interRAI definition of a fall.
  • Describe the rationale and evidence for multifactorial assessment and interventions.
  • Discuss ways of talking about falls with older people and their families/ whānau and how to manage falls risks.

Falls are the most common and costly injury for older people1 and falls (with or without injury) are an independent predictor of admission to age-related residential care2.

A national programme, Reducing Harm from Falls, is aimed at preventing falls and reducing fall-related harm in older people. The three-year programme is led by the Health Quality & Safety Commission in partnership with the Accident Compensation Corporation (ACC) and other stakeholders. In the programme’s expert advisory group are clinicians, care providers, researchers, and consumers who understand the impact and personal costs of a fall for an older person and their family/whānau.

Practices that make the care environment safer for all older people (irrespective of their risk of falling) are essential elements in falls prevention3, but the purpose of this article is to outline the national programme’s Ask, assess, act process as an individualised approach to preventing falls.

Ask, assess, act principles apply in all settings, and the process can complement existing screening, assessment, and planning tools. The process is particularly useful in hospital settings (inpatients, outpatients, and emergency departments), primary health care, and home-based care.

Older people and falls

Older people are defined as those aged 65 and over, a group increasing in number due to trends in improved health and more effective health care. This group ranges from those who are generally healthy and active to the significant proportion (25-50 per cent) of those over 85 estimated to be frail4.

Falls occur at all ages, but for older people, a high incidence of falls combines with:

  • high susceptibility to injury because of age-related physiological changes (such as slower protective reactions) and
  • high prevalence of clinical conditions implicated in increasing risk of falling (such as postural hypotension) or risk of injury (such as osteoporosis)1.

The most serious injuries resulting from falls are head injuries and fractures, with hip fracture the most common fracture after the age of 751. Even without physical injury, a fall can create anxiety and a loss of confidence in the person and their family/whānau or caregivers5.

Overall, around 30 per cent of generally healthy community-dwelling older people will fall at least once each year – mostly without serious injury, but about 5 per cent will have a fracture or require hospitalisation related to a fall. Fall and injury rates rise with age, and these figures double for community-dwelling people aged 75 years and over.


Definition of a fall

For consistency in risk assessment and reporting falls, the expert advisory group recommends the operational definition from interRAI assessment protocols: ‘Any unintentional change in position where the person ends up on the floor, ground, or other lower level; includes falls that occur while being assisted by others’6. Importantly, a fall is an unintended event, and contact with the floor is not necessary to count as a fall.


The Ask, assess, act process

The Ask, assess, act process conforms closely to recommendations in current clinical guidelines7 because it is based on the same strong evidence from systematic reviews: falls in older people in hospital and community settings can be prevented by implementing interventions and supports which address their individual risk factors8,9.

This ‘multifactorial’ approach recognises that older people may have a number of risk factors, which may be inter-related (at the same time, just one factor can put an older person at risk). Because every older person is different, they have different risk factors, and need different interventions and supports.

The process helps target who will benefit from multifactorial assessment and intervention. The first step is to screen older people to identify those at risk of falling. For those at risk, the second step involves undertaking a systematic assessment of falls-related risks factors that could be treated, modified or better managed10. The third, and most important step, is actioning a plan of interventions and supports (including referral for specialist input as needed) to address the risks identified for this person10.


The Commission has developed a set of downloadable resources for the Ask, assess, act which include:

  • Informational poster
  • Helpsheet
  • Patient letter for those at risk
  • Learning activities.

Start by asking about falls

Make it routine to ask whether an older person has fallen in the past year, and enquire about the frequency, context and characteristics of any falls11,12. Explanation of a fall as ‘an accident’ due to an identified hazard in the environment should be probed further. Falls are often the result of an interaction between the hazard and the person’s accumulated age-related changes in functioning and disease processes, rather than being caused by the hazard alone1.

Falls – and their causes – may go without clinical attention simply because health professionals don’t ask and older people might not mention that they have fallen13, particularly if there was no injury or they are anxious about the possibility of going into residential care.

ASK: Have you slipped, tripped, or fallen in the last year?

  • Having fallen previously is predictive of falling again14, and in the hospital setting, it’s an especially worthwhile question, as about 50 per cent of inpatients who fall have fallen before15.
  • When talking with older people about their fall experiences, asking about ‘slipping, tripping, stumbling, or losing balance’ is recommended, as these are the words older people themselves might use, and they capture near falls16.

ASK: Can you get out of a chair without using your hands?

  • Asking about whether an older person uses their hands to push up out of a chair is an abbreviated form of the ‘sit to stand’ test17.
  • A demonstration that this is the case, or a positive answer indicates further investigation of balance problems and lower limb weakness will be needed.

ASK: Are there some activities you’ve stopped doing because you are afraid you might lose your balance? Do you worry about falling?

  • Restricting physical and social activities to reduce the risk of falling reduces quality of life and ‘fear of falling’ can create a downward spiral in which loss of condition increases risk5.
  • In one study, 19 per cent of a sample of community-dwellers (both with and without a fall in the last year) aged 75 and over acknowledged activity avoidance18.

Assess by risk factors using a consistent approach

Checklists covering common falls risk factors are recommended to ensure no factors are missed in assessment19,20. The Ask, assess, act resources developed for the programme group risk factors in relation to physical activity, medical risks associated with underlying conditions, and home safety21.

Standardised documentation also facilitates consistency, whether in separate documents or specific falls sections in general assessment tools10, such as the care-planning component developed for the TrendCare workload management system22.

Assessment by risk factors is an ongoing process necessarily integrated with care planning. It is not a once-only task, as new risk factors may present as an older person’s functioning and conditions change.

What about risk prediction scores?

Falls risk prediction tools are those that aim to calculate a person’s risk of falling in a numerical score, either in terms of ‘at risk/not at risk’, or ‘low/medium/high risk’.

However, there are questions about the validity and reliability of risk prediction tools, and concerns that arriving at a score may lead staff to feel that ‘something has been done’ without any substantive action being taken15.

Another problem arises where the score is used to match an older person’s ‘amount’ of risk to a predetermined set of interventions – some interventions may be irrelevant and some may be missing15,21.

For these reasons, the use of predictive risk scoring tools is a ‘Do not’ recommendation in the National Institute for Health and Care Excellence 2013 clinical guideline12.

Act to implement individualised interventions and supports

Assessment by risk factors results in an individualised plan of care in which interventions and supports address identified risk factors. Managing falls risks is not an ‘extra’ – for example, problems with urinary continence or urgency warrant the interdisciplinary team’s attention in any case, and medicine use review is an ongoing process. Referrals for specialist input may be needed.

What you bring as a nurse to the Ask, assess, act process

The commission’s Quality and Safety Markers (QSMs) for falls pose the question: ‘Are we doing the right things?23. The two markers measure the extent to which risk assessment and care planning are carried out for older inpatients at risk of falling. Apart from evidence already noted for the effectiveness of multifactorial interventions in this group8, risk assessment is a component commonly found in effective falls prevention programmes24.

While measuring that the right things are being done is important, the qualitative aspects of ‘how’ they are done is even more important.

Critical thinking and clinical judgement

The way an older person moves tells you about problems and confidence in mobilising – add to that knowledge of their health history, and it’s no surprise that clinical observation and judgement matches or outperforms falls risk prediction tools25. A study of inpatient preferences found that clinical attention – a multifactorial approach including a review by a health professional – was valued highest26. What makes risk assessment and care planning valuable is not simply ‘ticking boxes’ – but a focus on the person.

A positive conversation

Attunement to whether this older person fears falling or believes it is something that happens to other people27 guides the way you ‘have the conversation’ about falls. It’s possible that the person who has had a fall is more open to the information that, while the risk of falling does increase with age, falls are likely but not inevitable – and “… you can do something about it”28. The goal is to help older people identify their risks and management options, choose the actions they can realistically take themselves, and make decisions about the options offered in an interdisciplinary approach.

Eliciting the older person’s insights and preferences

For the older person at risk of falling, a partnership approach involves them, their families/whānau, and others involved in their care. It means:

  • asking what they believe were the causes of a fall, and how they think they can avoid further falls
  • understanding what they see as major health problems and their main falls risk factors
  • prioritising and limiting the number of fall prevention recommendations if they already feel overwhelmed by their situation
  • checking for preferences and what is manageable (e.g. choosing between referral to a home-based or group exercise programme), and what ‘trade-offs’ are acceptable (e.g. reducing or stopping medicines associated with higher risk of falling)
  • identifying their personal strengths and supporting their resilience29.
