Improving clinical pathway design: lessons learned from a computerised prototype.

Increasing costs of health care, fuelled by demand for high quality, cost-efficient health care has propelled hospitals to restructure their patient care delivery systems. One such effort is the adaptation of an engineering project management methodology, the critical path method (CPM), as a tool to organise, standardise and improve the quality of healthcare delivery and hence patient outcomes. However, the two-dimensional nature and the size of paper impose severe limitations on the manual clinical pathways currently in use by hospitals. This paper analyses these inherent limitations and discusses some of the problems encountered in an attempt in early 1996 to create an electronic care map planner (CMP) based on the precedence diagramming method (PDM) model. It also reports on a current project to create a computerised clinical pathway tool to resolve the identified problems.
