Document Summary

Quiz 5: interventions for preventing falls in older people living in the community (review) Background: approximately 30% of people over 65 years of age living in the community fall each year. Data collection and analysis: 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. Most trials compared a fall prevention intervention with no intervention or an intervention not expected to reduce falls. Overall, exercise interventions significantly reduced the risk of sustaining a fall-related fracture (rr 0. 34, 95% ci 0. 18 to 0. 63; 6 trials; 810 participants) Vitamin d did not reduce rate of falls or risk of falling but may do so in people with lower vitamin d levels before treatment.
