A decade of case management: a methodological review of outcome research.

The last decade has witnessed a burgeoning interest in case management services to people with severe mental illness. While the literature on case management is proliferating, there remains a paucity of rigorously designed outcome research. This paper provides a methodological review of that outcome research on case management, which found that the term case management is used to describe a diverse array of interventions that yield differing client outcomes. Suggestions for the direction of future inquiry are described.
