ABSTRACT:

Keywords:

  • fall prevention;
  • residential care;
  • cluster randomized controlled trial
Objectives: To establish the effectiveness of a fall-prevention program in reducing falls and injurious falls in older residential care residents.
Design: Cluster, randomized, controlled trial.
Setting: Fourteen randomly selected residential care homes in Auckland, New Zealand.
Participants: All older residents (n=628, 95% participation rate).
Intervention: Residential care staff, using existing resources, implemented systematic individualized fall-risk management for all residents using a fall-risk assessment tool, high-risk logo, and strategies to address identified risks.
Measurements: Number of residents sustaining a fall, falls, and injurious-falls incidence rates.
Results: During 12 months of follow-up, 103 (43%) residents in the control group and 173 (56%) residents in the intervention group fell (P<.018). There was a significantly higher incidence rate of falls in intervention homes than in control homes (incident rate ratio=1.34, 95% confidence interval=1.06–1.72) during the intervention period after adjusting for dependency level (type of home), baseline fall rate, and clustering. There was no difference in the injurious fall incidence rate or incidence of serious injuries.
Conclusion: This fall-prevention intervention did not reduce falls or injury from falls. Low-intensity intervention may be worse than usual care.

Features

A Meta-Analysis of Fall Prevention Programs for the Elderly: How Effective Are They?

Hill-Westmoreland, Elizabeth E.; Soeken, Karen; Spellbring, Ann Marie

Abstract

Background: Although fall prevention studies for the elderly have been reported, there is a paucity of work summarizing the effectiveness of these interventions.

Objectives: The research question that guided this study was: What are the effects of fall prevention programs on the proportion of falls in the elderly?

Method: Meta-analysis was employed to summarize findings of intervention studies of fall prevention in the elderly involving a comparison group and a quantifiable outcome. Studies were reviewed by two of the authors with the eligibility criteria in mind. Studies were then coded and an inter-rater reliability check was performed.

Results: The overall mean weighted effect size for the 12 studies included in the meta-analysis was .0779 (Z = 5.03, p < .001). For fall prevention intervention types, exercise alone had a mean weighted effect size of .0220 (Z = .5303, p > .5), exercise and risk modification had a mean weighted effect size of .0687 (Z = 3.41, p < .001), and comprehensive risk assessment intervention studies had an effect size of .1231 (Z = 3.97, p < .001). The mean weighted effect size size for community-based studies was .0972 (Z = 5.37, p < .001) and for institution-based studies was .0237 (Z = .7822, p = .22). Time to outcome measure analyses revealed that the mean weighted effect size for studies measuring proportion of falls at 12 months was .0905 (Z = 5.43, p < .001), and those measuring at four months or less was -.0972 (Z = -.005, p > .50).

Conclusions: The results of this meta-analysis indicate that there was a 4% decrease in the rate of falls for individuals who were in the treatment groups receiving various fall prevention interventions. Additional intervention studies need to be conducted in the elderly population with a goal of preventing falls.

In dieser o.g. Untersuchung scheint es allerdings etwa querbeet zu gehen - teilweise werden Interventionen verglichen, die sich eigentlich nicht vergleichen lassen, da sowohl der Aufbau wie auch die Intervention nicht unbedingt vergleichbar sind.

OBJECTIVES: To determine the effects of exercise on falls prevention in older people and establish whether particular trial characteristics or components of exercise programs are associated with larger reductions in falls.
DESIGN: Systematic review with meta-analysis. Randomized controlled trials that compared fall rates in older people who undertook exercise programs with fall rates in those who did not exercise were included.
SETTING: Older people.
PARTICIPANTS: General community and residential care.
MEASUREMENTS: Fall rates.
RESULTS: The pooled estimate of the effect of exercise was that it reduced the rate of falling by 17% (44 trials with 9,603 participants, rate ratio (RR)=0.83, 95% confidence interval (CI)=0.75–0.91, P<.001, I2=62%). The greatest relative effects of exercise on fall rates (RR=0.58, 95% CI=0.48–0.69, 68% of between-study variability explained) were seen in programs that included a combination of a higher total dose of exercise (>50 hours over the trial period) and challenging balance exercises (exercises conducted while standing in which people aimed to stand with their feet closer together or on one leg, minimize use of their hands to assist, and practice controlled movements of the center of mass) and did not include a walking program.
CONCLUSION: Exercise can prevent falls in older people. Greater relative effects are seen in programs that include exercises that challenge balance, use a higher dose of exercise, and do not include a walking program. Service providers can use these findings to design and implement exercise programs for falls prevention.
The development and implementation of effective and cost-efficient strategies to prevent falls in older people is an urgent global health challenge. In developed countries, life expectancy for people aged 65 years old is approximately 17 years for men and 21 years for women. At least one-third of people aged 65 and older fall at least once annually,1 and falls account for more than half of the injury-related hospitalizations for older people.2 Fall rates in the general older population are reported to be 1.2 falls per person year.3
Falls in older people are not purely random events but can be predicted by assessing a number of risk factors.4,5 Some of these risk factors (e.g., reduced muscle strength and impaired balance and gait) can be modified using exercise, whereas others (e.g., poor vision, psychoactive medication use) require different intervention approaches. Exercise can be used as a stand-alone falls prevention intervention or as a component of a multifaceted program. Multifaceted interventions can prevent falls in the general community, in those at greater risk of falls, and in residential care facilities.4,6
Many trials have sought to establish the specific effect of exercise on fall rates, but a large proportion of these trials have been underpowered. The best way to interpret these trials may be to pool their data in a meta-analysis, but trials of the effects of exercise on fall rates vary in their quality, have been conducted on a range of populations, and employ exercise programs that differ greatly in their aims and content. Meta-analysis should therefore involve exploration of whether these factors “explain” (are associated with) estimates of the effect of exercise programs.7,8
A Cochrane review of fall prevention strategies6 conducted separate meta-analyses on different forms of exercise and concluded that some exercise programs can prevent falls in community dwellers (e.g., home exercise program of balance and strength training, a Tai Chi group program) but that others are unlikely to be beneficial (brisk walking in women with an upper limb fracture in the previous 2 years) or require further investigation (untargeted group-based exercise interventions and individual lower-limb strength training).

A limitation to this approach is that it combines programs that may be different (e.g., group programs that are of low and high intensity) and separates programs that share key features (e.g., balance training).
This study sought to establish the effect of exercise on fall rates, with a major aim of explaining between-trial variability. Meta-regression methods were used to investigate whether particular features of study populations, exercise programs, and study design were associated with the size of estimates of effects of exercise on fall rates.

A Randomized Controlled Trial of Fall Prevention Strategies in Old Peoples’ Homes

A Randomized Controlled Trial of Fall Prevention Strategies in Old Peoples’ Homes

McMurdo MET, Millar AM, Daly F

Gerontology 2000;46:83–87 (DOI: 10.1159/000022139) 

 Abstract:
 
Background: 


Falls are a major cause of morbidity in old age. A small number of fall prevention trials in cognitively intact community-dwelling older people have been effective. This study set out to examine the preventability of falls in older people living in institutional care. 

Objective: 

To evaluate the effectiveness of falls risk factor assessment/modification and seated balance exercise training in reducing falls among elderly people living in residential care. Methods: 133 residents with a mean age of 84± (SD) 6.8 years were allocated at random by home to receive either a 6-month falls risk factor assessment/modification and seated balance exercise training programme (n = 77) or 6 months of reminiscence therapy (n = 56). The risk factors targeted were postural hypotension, polypharmacy, visual acuity, and ambient lighting levels. Falls risk factor assessments and recommendation for modifications were performed at baseline in the intervention group and assessments repeated at 6 months. Functional reach, reaction time, timed up-and- go, grip strength, spinal flexibility, and Philadelphia Geriatric Centre Morale Scale and Mini-Mental State Examination scores were determined at baseline and at 6 months by a ‘blind’ observer. Falls and fractures were then monitored in both groups during a 7- to 12-month falls-monitoring follow-up period. 

Results: 

Only 90 of 133 (67.7%) residents completed the 6-month intervention period, and 84 (63.2%) completed the 7- to 12-month falls-monitoring follow-up period. Both prevalence of postural hypotension (p = 0.0005) and poor visual acuity (p = 0.04) were reduced in the intervention group. There was no difference between the groups in the number of falls sustained, the risk of falling [odds ratio 0.45 (95% CI 0.19–1.14)], or in the risk of recurrent falling [odds ratio 1.07 (95% CI 0.40–2.97)]. No significant differences were found between the groups with regard to change in other outcome measures. 

Conclusions: 

 The high drop-out rate reduced the power of this study to detect any effect of the interventions used. It is possible that either the exercises were not sufficiently vigorous or that to improve balance exercises must be performed standing. Further research is required to identify effective fall prevention strategies for elderly people in residential settings.
