Why invest in falls prevention?Overview of reasons
Falls and injuries in older people are common Increasing numbers, costs, as population ages Falls can be prevented (evidence from 220
randomised controlled trials) Need to maintain independence and quality of life Effective, targeted strategies represent good value
for money (cost savings in 1 year)
![Page 3: Falling costs: the case for investment](https://reader036.vdocument.in/reader036/viewer/2022062315/568160aa550346895dcfcca5/html5/thumbnails/3.jpg)
Falls are common events for older people
35% of 65–79 year olds 45% of 80–89 year olds 55% of 90+ year olds

Impact of falls Leading cause of injury in ≥65 year olds
Fractures, traumatic brain injuries, death Older people have the highest risk of early
death or serious injury from a fall Falls result in:
Loss of confidence, fear of further fallsRestriction of activitiesReduced mobility and loss of physical functionAdmission to aged residential care
![Page 5: Falling costs: the case for investment](https://reader036.vdocument.in/reader036/viewer/2022062315/568160aa550346895dcfcca5/html5/thumbnails/5.jpg)
Falls cost $$$
47,000 fall related discharges in New Zealand, $205m (public hospitals) per annum Over half were aged 65+ 86% of 65+ community living (from NSW data)
49% of spending on fall related healthcare in older population is for hospital inpatients, 41% for aged residential care (UK study)
Fall with minor injury
Hip fracture,3 weeks in hospital
Hip fracture, discharge to aged residential care
$600 $47,000 $135,000

Investing in falls prevention Biggest potential for cost saving occurs in
community living older people ED presentations Hospital admissions Admissions to aged residential care
Spend money on proven strategies only Careful targeting gives best value for money

Effective strategies in care Residential aged care facilities (43 trials)
Vitamin D supplements (40% reduction) Exercise programmes? Medication review? Multifactorial interventions?
Hospitals (17 trials) Additional physiotherapy (64% fewer fallers) Unit specialising in geriatric orthopaedic care compared with
standard orthopaedic ward (66% reduction) Individually targeted multifactorial interventions (31% reduction
but effect noted only after 45 days) More falls on carpet than vinyl floors

Recommended strategies1. Multiple-component exercise programmes
Otago Exercise Programme (≥80 years, delivered at home) Group classes (≥75 years) Tai Chi classes (for more active older people)
2. Vitamin D supplements for all older people with a risk factor for low levels of vitamin D
3. Home safety assessment and modification by OT Previous faller discharged from hospital Severe visual impairment
4. Multifactorial approach – assessment of the individual, treatment based on identified risk factors Individual presenting to GP, ED with a fall, falls clinic, hospital
admission, aged care residents

Key message Spend money on falls prevention
Benefit health, safety, and independence of older person
Benefit to family, formal and informal carers, health professionals, community
Cost savings for providers, health system Do nothing?
Unthinkable! Falls and injuries
