Development of a Comprehensive Medical Error Ontology

A critical step towards reducing errors in health care is the collection and assessment of medical error data so that potential harms to patients can be identified and steps taken to prevent or mitigate them. However, no standardized framework for classifying and evaluating such data currently exists. This paper describes our efforts in developing a comprehensive medical error ontology to serve as a standard representation for medical error concepts from various existing published taxonomies. Eight candidate taxonomies were selected from the published literature and merged to create a reference ontology consisting of 12 multidimensional axes that encompass all the aspects of a medical error event. The ultimate goal of the project is to use the medical error ontology to identify strategies for preventing future adverse events in health care.
