RESUMEN
PURPOSE: The purpose of this study is to evaluate the usefulness and necessity of an emergency medical service director program for board certified emergency physicians. METHODS: A retrospective analysis of records of direct medical advice provided by board certified emergency physicians in the Busan area from April 1, 2011 to July 11, 2011 was conducted. The medical and legal validity of the medical direction was evaluated by two independent emergency physicians with experience and certification in the field of medical control. RESULTS: Fifteen emergency physicians provided direct medical control during the study period. Five of them were certified as an emergency medical service (EMS) director by the Korean council of EMS physicians (KCEMSP), and the other 10 were not. An analysis of 992 cases of direct medical direction was performed. No differences in the diagnostic appropriateness and medical validity of medical advice were observed between the two groups. A significant difference was observed in legal validity (p=0.048). However, in multivariate analysis, experience as a certified emergency physician was a significant factor determining legal validity (p=0.02), while certification by the KCEMSP was not significant. CONCLUSION: The current EMS director certification program did not have a significant influence on the appropriateness of direct medical direction. EMS director courses and emergency medicine residency programs are in need of improvement in the legal aspect of prehospital emergency service.
