Physicians, Guidelines, and Cognitive Tasks

Using a case study analysis of the Expert Panel Report 3 (EPR-3): Guidelines for the Diagnosis and Treatment of Asthma, this article compares the workflows and knowledge requirements of primary care practice to the structure and content of a well-respected set of clinical guidelines. The authors show that there are discrepancies between physician workflow and the structure of the EPR-3, as well as between physicians' knowledge requirements and the content of the EPR-3. The analysis suggests that closing the gap between medical knowledge and practice will require alternative ways to represent guidelines' knowledge and recommendations.
