Abstract

BACKGROUND:

Falls in care facilities and hospitals are common events that cause considerable morbidity and mortality for older people. This is an update of a review first published in 2010.

OBJECTIVES:

To assess the effectiveness of interventions designed to reduce falls by older people in care facilities and hospitals.

SEARCH METHODS:

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (March 2012); The Cochrane Library 2012, Issue 3; MEDLINE, EMBASE, and CINAHL (all to March 2012); ongoing trial registers (to August 2012), and reference lists of articles.

SELECTION CRITERIA:

Randomised controlled trials of interventions to reduce falls in older people in residential or nursing care facilities or hospitals.

DATA COLLECTION AND ANALYSIS:

Two review authors independently assessed risk of bias and extracted data. We used a rate ratio (RaR) and 95% confidence interval (CI) to compare the rate of falls (e.g. falls per person year) between intervention and control groups. For risk of falling we used a risk ratio (RR) and 95% CI based on the number of people falling (fallers) in each group. We pooled results where appropriate.

MAIN RESULTS:

We included 60 trials (60,345 participants), 43 trials (30,373 participants) in care facilities, and 17 (29,972 participants) in hospitals.Results from 13 trials testing exercise interventions in care facilities were inconsistent. Overall, there was no difference between intervention and control groups in rate of falls (RaR 1.03, 95% CI 0.81 to 1.31; 8 trials, 1844 participants) or risk of falling (RR 1.07, 95% CI 0.94 to 1.23; 8 trials, 1887 participants). Post hoc subgroup analysis by level of care suggested that exercise might reduce falls in people in intermediate level facilities, and increase falls in facilities providing high levels of nursing care.In care facilities, vitamin D supplementation reduced the rate of falls (RaR 0.63, 95% CI 0.46 to 0.86; 5 trials, 4603 participants), but not risk of falling (RR 0.99, 95% CI 0.90 to 1.08; 6 trials, 5186 participants).For multifactorial interventions in care facilities, the rate of falls (RaR 0.78, 95% CI 0.59 to 1.04; 7 trials, 2876 participants) and risk of falling (RR 0.89, 95% CI 0.77 to 1.02; 7 trials, 2632 participants) suggested possible benefits, but this evidence was not conclusive.In subacute wards in hospital, additional physiotherapy (supervised exercises) did not significantly reduce rate of falls (RaR 0.54, 95% CI 0.16 to 1.81; 1 trial, 54 participants) but achieved a significant reduction in risk of falling (RR 0.36, 95% CI 0.14 to 0.93; 2 trials, 83 participants).In one trial in a subacute ward (54 participants), carpet flooring significantly increased the rate of falls compared with vinyl flooring (RaR 14.73, 95% CI 1.88 to 115.35) and potentially increased the risk of falling (RR 8.33, 95% CI 0.95 to 73.37).One trial (1822 participants) testing an educational session by a trained research nurse targeting individual fall risk factors in patients at high risk of falling in acute medical wards achieved a significant reduction in risk of falling (RR 0.29, 95% CI 0.11 to 0.74).Overall, multifactorial interventions in hospitals reduced the rate of falls (RaR 0.69, 95% CI 0.49 to 0.96; 4 trials, 6478 participants) and risk of falling (RR 0.71, 95% CI 0.46 to 1.09; 3 trials, 4824 participants), although the evidence for risk of falling was inconclusive. Of these, one trial in a subacute setting reported the effect was not apparent until after 45 days in hospital. Multidisciplinary care in a geriatric ward after hip fracture surgery compared with usual care in an orthopaedic ward significantly reduced rate of falls (RaR 0.38, 95% CI 0.19 to 0.74; 1 trial, 199 participants) and risk of falling (RR 0.41, 95% CI 0.20 to 0.83). More trials are needed to confirm the effectiveness of multifactorial interventions in acute and subacute hospital settings.

AUTHORS' CONCLUSIONS:

In care facilities, vitamin D supplementation is effective in reducing the rate of falls. Exercise in subacute hospital settings appears effective but its effectiveness in care facilities remains uncertain due to conflicting results, possibly associated with differences in interventions and levels of dependency. There is evidence that multifactorial interventions reduce falls in hospitals but the evidence for risk of falling was inconclusive. Evidence for multifactorial interventions in care facilities suggests possible benefits, but this was inconclusive.
