As people get older, they may fall more often for a variety of reasons including problems with balance, poor vision, and dementia. Up to 30% may fall in a year. Although one in five falls may require medical attention, less than one in 10 results in a fracture.
This review looked at the healthcare literature to establish which fall prevention interventions are effective for older people living in the community, and included 159 randomised controlled trials with 79,193 participants.  
Group and home-based exercise programmes, usually containing some balance and strength training exercises, effectively reduced falls, as did Tai Chi. Overall, exercise programmes aimed at reducing falls appear to reduce fractures.
Multifactorial interventions assess an individual's risk of falling, and then carry out treatment or arrange referrals to reduce the identified risks. Overall, current evidence shows that this type of intervention reduces the number of falls in older people living in the community but not the number of people falling during follow-up. These are complex interventions, and their effectiveness may be dependent on factors yet to be determined.  
Interventions to improve home safety appear to be effective, especially in people at higher risk of falling and when carried out by occupational therapists. An anti-slip shoe device worn in icy conditions can also reduce falls.
Taking vitamin D supplements does not appear to reduce falls in most community-dwelling older people, but may do so in those who have lower vitamin D levels in the blood before treatment.  
Some medications increase the risk of falling. Three trials in this review failed to reduce the number of falls by reviewing and adjusting medications. A fourth trial involving family physicians and their patients in medication review was effective in reducing falls. Gradual withdrawal of a particular type of drug for improving sleep, reducing anxiety, and treating depression (psychotropic medication) has been shown to reduce falls.
Cataract surgery reduces falls in women having the operation on the first affected eye. Insertion of a pacemaker can reduce falls in people with frequent falls associated with carotid sinus hypersensitivity, a condition which causes sudden changes in heart rate and blood pressure.
In people with disabling foot pain, the addition of footwear assessment, customised insoles, and foot and ankle exercises to regular podiatry reduced the number of falls but not the number of people falling.
The evidence relating to the provision of educational materials alone for preventing falls is inconclusive.

Interventions for preventing falls in older people living in the community

Guideline for the Prevention of Falls in Older Persons

Background 
Approximately 30% of people over 65 years of age living in the community fall each year.
Objectives
To assess the effects of interventions to reduce the incidence of falls in older people living in the community.
Search strategy
We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, CENTRAL (The Cochrane Library 2008, Issue 2), MEDLINE, EMBASE, CINAHL, and Current Controlled Trials ( all to May 2008).
Selection criteria
Randomised trials of interventions to reduce falls in community-dwelling older people. Primary outcomes were rate of falls and risk of falling.
Data collection analysis
Two review authors independently assessed trial quality and extracted data. Data were pooled where appropriate.
Main results
We included 111 trials ( 55,303 participants). Multiple-component group exercise reduced rate of falls and risk of falling (rate ratio (RaR) 0.78, 95% CI 0.71 to 0.86; risk ratio (RR) 0.83, 95% CI 0.72 to 0.97), as did Tai Chi ( RaR 0.63, 95% CI 0.52 to 0.78; RR 0.65, 95% CI 0.51 to 0.82), and individually prescribed multiple-component home-based exercise ( RaR 0.66, 95% CI 0.53 to 0.82; RR 0.77, 95% CI 0.61 to 0.97).
Assessment and multifactorial intervention reduced rate of falls (RaR 0.75, 95% CI 0.65 to 0.86), but not risk of falling.
Overall, vitamin D did not reduce falls ( RaR 0.95, 95% CI 0.80 to 1.14; RR 0.96, 95% CI 0.92 to 1.01), but may do so in people with lower vitamin D levels.
Overall, home safety interventions did not reduce falls ( RaR 0.90, 95% CI 0.79 to 1.03); RR 0.89, 95% CI 0.80 to 1.00), but were effective in people with severe visual impairment, and in others at higher risk of falling. An anti- slip shoe device reduced rate of falls in icy conditions ( RaR 0.42, 95% CI 0.22 to 0.78).
Gradual withdrawal of psychotropic medication reduced rate of falls ( RaR 0.34, 95% CI 0.16 to 0.73), but not risk of falling. A prescribing modification programme for primary care physicians significantly reduced risk of falling ( RR 0.61, 95% CI 0.41 to 0.91).
Pacemakers reduced rate of falls in people with carotid sinus hypersensitivity ( RaR 0.42, 95% CI 0.23 to 0.75). First eye cataract surgery reduced rate of falls ( RaR 0.66, 95% CI 0.45 to 0.95).
There is some evidence that falls prevention strategies can be cost saving.
Authors' conclusions
Exercise interventions reduce risk and rate of falls. Research is needed to confirm the contexts in which multifactorial assessment and intervention, home safety interventions, vitamin D supplementation, and other interventions are effective.

Interventions for preventing falls in older people living in the community (Review)

The prevention of injury associated with falls in older people is a public health target in many countries around the world. Although there is good evidence that interventions such as multifactorial fall prevention and individually prescribed exercise are effective in reducing falls, the effect on serious injury rates is unclear. Historically, trials have not been adequately powered to detect injury endpoints, and variations in case definition across trials have hindered meta-analysis. It is possible that fall-prevention strategies have limited effect on falls that result in injuries or are ineffective in populations who are at a higher risk of injury. Further research is required to determine whether fall-prevention interventions can reduce serious injuries. Prevention of Falls Network Europe (ProFaNE) is a collaborative project to reduce the burden of fall injury in older people through excellence in research and promotion of best practice (www.profane.eu.org). The European Commission funds the network, which links clinicians, members of the public, and researchers worldwide. The aims are to identify major gaps in knowledge in fall injury prevention and to facilitate the collaboration necessary for large-scale clinical research activity, including clinical trials, comparative research, and prospective meta-analysis. Work is being undertaken in a 4-year program. As a first step, the development of a common set of outcome definitions and measures for future trials or meta-analysis was considered.

Background. The aim of this study was to assess the impact of fear of falling on the health of older people. Methods. A total of 528 subjects (mean age 77 years) were recruited from two hospitals in Sydney, Australia, and followed for approximately 12 months. Eighty-five subjects died during follow-up, and 31 were admitted to an aged care institution. Tinetti’s Falls Efficacy Scale (FES) was successfully administered to 418 subjects as part of the baseline assessment. Among those with baseline FES scores, ability to perform 10 activities of daily living (ADLs) was assessed at baseline and follow-up in 307 subjects, and SF-36 scores were assessed at baseline and follow-up in 90 subjects recruited during the latter part of the study. Falls during follow-up were identified using a monthly falls calendar. Results. Compared with those with a high fall-related self-efficacy (FES score 5 100), those with a low fall-related self-efficacy (FES score # 75) had an increased risk of falling (adjusted relative risk 2.09, 95% confidence interval [CI] 1.31‐3.33). Those with poorer fall-related self-efficacy had greater declines in ability to perform ADLs ( p , .001): the total ADL score decreased by 0.69 activities among persons with low FES scores ( # 75) but decreased by only 0.04 activities among persons with FES scores of 100. Decline in ADLs was not explained by the higher frequency of falls among persons with low FES scores. SF-36 scores (particularly scores on the Physical Function and Bodily Pain subscales) tended to decline more among persons with poor fall-related self-efficacy. Nonfallers who said they were afraid of falling had an increased risk of admission to an aged care institution. Conclusions. Fear of falling has serious consequences for older people. Interventions that successfully reduce fear of falling and improve fall-related self-efficacy are likely to have major health benefits.

Prospective Study of the Impact of Fear of Falling on Activities of Daily Living, SF-36 Scores, and Nursing Home Admission

OBJECTIVE: To determine whether occupational therapist home visits targeted at environmental hazards reduce the risk of falls

DESIGN: A randomized controlled trial

SETTING: Private dwellings in the community in Sydney, Australia

PARTICIPANTS: A total of 530 subjects (mean age 77 years), recruited primarily before discharge from selected hospital wards

INTERVENTION: A home visit by an experienced occupational therapist, who assessed the home for environmental hazards and facilitated any necessary home modifications

MEASUREMENTS: The primary study outcome was falls, ascertained over a 12-month follow-up period using a monthly falls calendar

RESULTS: Thirty six percent of subjects in the intervention group had at least one fall during follow-up, compared with 45% of controls (P = 050) The intervention was effective only among subjects (n = 206) who reported having had one or more falls during the year before recruitment into the study; in this group, the relative risk of at least one fall during follow-up was 064 (95% confidence interval, 050-083) Similar results were obtained when falls data were analyzed using survival analysis techniques (proportional and multiplicative hazards models) and fall rates (mean number of falls per person per year) About 50% of the recommended home modifications were in place at a 12-month follow-up visit

CONCLUSIONS: Home visits by occupational therapists can prevent falls among older people who are at increased risk of falling However, the effect may not be caused by home modifications alone Home visits by occupational therapists may also lead to changes in behavior that enable older people to live more safely in both the home and the external environment J Am Geriatr Soc 47:1397–1402, 1999

Home visits by an occupational therapist for assessment and modification of environmental hazards: a randomized trial of falls prevention.

The objective of this study was to investigate the extent and nature of food advertising during Australian children's television (TV) viewing hours and programs, and to determine whether confectionery and fast food restaurant advertisements were more likely to be broadcast during children's programs than during adults' programs on Sydney television stations. One week (390 h) of Australian advertising data broadcast during children's TV viewing hours over 15 television stations were analysed to determine the proportion of food advertisements and, in turn, the proportion of those advertisements promoting foods high in fat and/or sugar. One week (346 h) of confectionery and fast food restaurant advertisements broadcast over three Sydney television stations were analysed to determine whether these types of advertisements were more likely to be advertised during children's programs than adults' programs. Half of all food advertisements promoted foods high in fat and/or sugar. 'Confectionery' and 'fast food restaurants' were the most advertised food categories during children's TV viewing hours. Confectionery advertisements were three times as likely, and fast food restaurant advertisements twice as likely, to be broadcast during children's programs than adults' programs. It can be concluded that foods most advertised during children's viewing hours are not those foods that contribute to a healthy diet for children. Confectionery and fast food restaurant advertising appears to target children. Australian children need protection from the targeted promotion of unhealthy foods on television, but currently little exists.

Food advertising on Australian television: the extent of children's exposure

Objective This study examined adherence to home modification recommendations made by an occupational therapist and attempted to identify predictors of adherence. Method An experienced occupational therapist visited the homes of 178 people (mean age = 764 years) to evaluate for and recommend appropriate home modifications for falls prevention. One year later, a research assistant visited these persons' homes to assess adherence. Results At least one home modification was recommended in 150 of the 178 homes visited. The most common recommendations were to remove mats and throw rugs (48%), to change footwear (24%), and to use a nonslip bathmat (21%). In the 121 homes revisited after 12 months, 419 home modifications had been recommended, and 216 (52%) were met with partial or complete adherence. The only significant predictors of adherence were a belief that home modifications can prevent falls and having help at home from relatives. Conclusion A major barrier to adherence to home modification recommendations is that many older people do not believe that home modifications can reduce their risk of falling.
