The evidence base for case management practice.

Little is known about the role performance of case managers, who come from a variety of professional disciplines. The purpose of this secondary analysis is to identify and compare case management (CM) activities and knowledge elements by professions and by work settings. In an online field survey conducted by the Commission for Case Manager Certification in 2004, 4,419 case managers rated the frequency and importance of 103 activities (8 domains) and 64 knowledge statements (6 domains).
