Measures to Secure Waiting Time for Dispatch of 119 Emergency Medical Service Units through the Analysis of the Emergency Activity Log

The number of individuals using the 119 emergency medical service (EMS) unit is increasing annually, and the Metropolitan Fire Headquarters attempts to increase the number of service individuals and vehicles; however, this has not been performed. The n‘umber of dispatches of the existing 119 EMS Unit is increasing. According to the analysis of the 119 paramedics’ emergency activity log, the waiting time for the dispatch of the 119 EMS unit decreased because of the increase in the number of dispatches. Consequently no other dispatch was possible for the 119 EMS unit. Since new emergency dispatches cannot be performed if the 119 EMS is busy, there is a vacancy in their area of jurisdiction, resulting in a dispatch gap. If a cardiac arrest occurs in an area with a dispatch gap, a 119 EMS unit from another area will be dispatched, making it difficult to secure timely emergency services. In solution, we found that there were many dispatches for non-emergency patients, and if these non-emergency patients are transferred to the non-emergency units, the 119 EMS unit can effectively assist patients with cardiac arrest.
