RESUMO
PURPOSE: Medical direction is an integral part of proper prehospital care, which is performed by EMS providers. In Gyunggi province, a number of measures have been implemented to improve the direct medical direction system. We aimed to report on the process and results of the newly implemented medical direction system. METHODS: This is a descriptive analysis of the newly implemented medical direction system for community EMS providers from June 2014 to October 2014. Direct medical direction was requested by emergency medical technicians (EMTs) during the study period, as follows: when a destination hospital was selected, EMTs requested medical direction from the physicians at the destination hospital. During the study period specially-trained advanced EMTs were permitted to perform intravenous (IV) access for fluid or glucose infusion without direct medical direction. EMTs were asked to complete records when they requested direct medical direction and performed IV access without medical direction. These records were collected and used in the analysis. RESULTS: Of 5949 direct medical direction requests, 5527 were analyzed; 2958 (53.5%) cases were requested to the destination hospitals, 2569 (46.5%) were requested to the centralized dispatch center. 'Patient evaluation' was the most common reason for EMTs to request medical direction to the destination hospitals (1680, 54.4%) and centralized dispatch center (980, 38.1%). EMTs' degree of satisfaction did not differ significantly between destination hospitals and the centralized dispatch center (4.12+/-0.82 and 4.09+/-0.84, p=0.053). IV access rate for hypotensive patients increased 6.1% during the study period compared to the same period of 2013 (17.6% and 11.5%, p<0.01). CONCLUSION: We found that it is feasible to request direct medical direction to the destination hospitals and perform IV access for fluid or glucose infusion without direct medical direction for specially-trained advanced EMTs. Continuing efforts to establish an optimized medical direction system would be required for proper pre-hospital care.
