Case management--a bottom-line care delivery model. Part II: Adaptation of the model.

Tuscson Medical Center's service volume management, research based approach to developing an adaptation of several design components of the New England Medical Center's case management model is described. The concept behind this model has been described (JONA 19(11):16-20). TMC's adaptation has been accomplished by operationalizing Rhea's steps to control variation in resource use through the (1) application of qualitative and quantitative research methods, (2) integration of other models, (3) inherent differences between the southwest and northeast settings, and (4) an organizational and participative planning structure and process.
