The 4 systematic reviews are a 2008 review from the Cochrane Collaboration by Cameron and colleagues (12), a 2008 review by Coussement and coworkers (13), a review by Oliver and colleagues originally published in 2007 (14) and then updated in 2010 as a narrative review (1), and a 2012 review by DiBardino and colleagues (15). All 4 reviews scored well on the assessment of multiple systematic reviews (AMSTAR) criteria for systematic reviews (11 out of 11, 10 out of 11, 10 out of 11, and 8 out of 11, respectively), which evaluates such items as comprehensiveness of the search, assessment of the quality of included studies, and methods for synthesizing the results (16). The Cochrane review searched for randomized trials to assess the effectiveness of fall reduction interventions for older adults in nursing care facilities and hospitals (12). Of the 41 included trials, 11 were conducted in hospital settings, 4 of which addressed multicomponent interventions. The review by Coussement and coworkers identified 4 multicomponent studies, 2 of which were included in the Cochrane review (13). The review by Oliver and colleagues used broader inclusion criteria than the Cochrane review, which led to the inclusion of 43 trials, case–control studies, and observational cohort studies (14). Thirteen of these studies were classified as multicomponent inpatient interventions. Oliver and coworkers' updated narrative review focused directly on hospital fall prevention and discussed 17 multicomponent studies spanning from 1999 to 2009, which include the 6 trials in the Cochrane and Coussement and colleagues' reviews (1,13). The recent review by DiBardino and coworkers (15) identified 6 primary research studies in the acute care inpatient setting, 3 of which were included in the Oliver and colleagues' 2010 update.
