The purpose of this study was to determine the prognosis of depression in elderly community and primary care populations.

The bibliographies of relevant articles were searched for additional references.

The validity of the studies was assessed according to the criteria for prognostic studies described by the Evidence-Based Medicine Working Group.
Information about the population, proportion of depressed subjects detected and treated by primary care physicians, length of follow-up, outcomes, and prognostic factors was systematically abstracted from each report.
All of the studies had some methodologic limitations.
A meta-analysis of outcomes at 24 months estimated that 33% of subjects were well, 33% were depressed, and 21% had died.
