Identifying inconsistencies in multiple clinical practice guidelines for a patient with co-morbidity

This paper describes a methodological approach to identifying inconsistencies when reconciling multiple clinical practice guidelines. The need to address these inconsistencies arises when a patient with co-morbidity has to be managed according to different treatment regimens. Starting with a well-known flowchart representation we discuss how to create a formal guideline model that allows for easy manipulations of its components. For this model we present how to identify conflicting actions that are manifested by treatment-treatment and treatment-disease interactions, and how to reconcile these conflicting actions.
