Why multifactorial fall-prevention interventions may not work: Comment on Multifactorial intervention to reduce falls in older people at high risk of recurrent falls'.

摘要

This well-done study by de Vries et al reports no significant decrease in falls with a multifactorial fall-prevention intervention. This is not the first negative study; there have been plenty. However, before we toll the death knell for multifactorial interventions as a prevention strategy, we need to figure out why multifactorial interventions appear to work in some studies but not others. What makes a multifactorial intervention succeed in reducing falls? Success may depend on 3 constructs: content, process, and choice of target group.
