Abstract

Results In 42 trials, the tested interventions prevented early readmissions (pooled random-effects relative risk, 0.82 [95%CI, 0.73-0.91]; P < .001; I2 = 31%), a finding thatwas consistent across patient subgroups. Trials published before 2002 reported interventions thatwere 1.6 times more effective than those tested later (interaction P = .01). In exploratory subgroup analyses, interventions with many components (interaction P = .001), involving more individuals in care delivery (interaction P = .05), and supporting patient capacity for self-care (interaction P = .04)were 1.4, 1.3, and 1.3 times more effective than other interventions, respectively. A post hoc regression model showed incremental value in providing comprehensive, postdischarge support to patients and caregivers.Conclusions and Relevance Tested interventions are effective at reducing readmissions, but more effective interventions are complex and support patient capacity for self-care. Interventions tested more recently are less effective.Jamainternal Medicine Preventing 30-Day Hospital Readmissions: A Systematic Reviewand Meta-analysis of Randomized Trials Aaron L.
