Abstract Although outpatient Comprehensive Geriatric Assessment (CGA) has shown certain benefits in functional status and quality of life by many randomized controlled trials, no survival benefit has been reported. We hypothesized that the lack of survival benefit may be due to insufficient power of individual trials. In order to assess the influence of outpatient CGA on survival of older persons, we performed a meta-analysis of all randomized controlled trials of outpatient CGA. Nine studies consisting of 3750 subjects fulfilled the predetermined eligible criteria and were included in the meta-analysis. Combined mortality risk ratio with outpatient CGA intervention compared to usual care group was 0.95 (95\% confidence interval, CI 0.82-1.12, P = 0.62). Treatment effects were homogeneous across the trials. This meta-analysis did not demonstrate survival benefit for outpatient CGA. Inadequate statistical power is unlikely to explain the results. Future researches of outpatient CGA should focus on coordinated and standardized measurement of outcomes related to functional status, institutionalization rate, and quality of life.
