Using PERT/CPM (Program Evaluation and Review Technique/Critical Path Method) to design and improve clinical processes.

Recent changes in health care have focused attention on new tools for planning and managing clinical processes. The use of one tool in particular, clinical pathways, has increased dramatically. Pathways employ a concept long used in other industries: the explicit design and documentation of a process. However, the most common tools used in other industries to perform process design, the Program Evaluation and Review Technique (PERT) and the Critical Path Method (CPM), have not migrated to health care. This article presents a methodology for incorporating PERT/CPM into the design and management of clinical processes.
