The purposes of this research which was conducted by surveying lost/added unit hours reports, unit hour demand analysis worksheets from prehospital care reports of two squads in Kyonggi Provincial Fire and Disaster Headquarters for 20 weeks (January 1, 2002 - May 20. 2002) are to get Unit Hour Utilization, Call Demands such as Unit Hour Demand, Simple Average Demand. High Average Demand, Peak Average Demand, the High Actual Demand.
The conclusions from this analysis were summarized as follows;
(1) By revealing Unit Hour Produced 3223.9, Call Volume 964. Unit Hour Utilization 0.299 at the Squad A and Unit Hour Produced 3328.4, Call Volume 901, Unit Hour Utilization 0.271 at the Squad B induced Korean Squads to chance identification, definition, direction of Unit Hour Utilization.
(2) By revealing Simple Average Demand 7.4 on Monday·Tuesday, High Average Demand 9.6 on Tuesday·Friday, Peak Average Demand 11.5 on Tuesday, the High Actual Demand 12 on Tuesday·Wednesday at the Squad A and Simple Average Demand 6.8 on Sunday, High Average Demand 10.4 on Monday, Peak Average Demand 11.5 on Monday, the High Actual Demand 13 on Monday at the Squad B enabled Korean Squads to utilize System Status Management.
(3) The Maximum Calls per Unit Hour were 115 for 23:00∼23:59, the Minimum Calls per Unit Hour were 46 for 05:00∼05:59 in two squads. The Maximum Calls per Unit Hour were 7.4 on Tuesday·Saturday, the Minimum Calls per Unit Hour were 6.1 on Thursday at the Squad A. The Maximum Calls per Unit Hour were 7.3 on Monday·Saturday, the Minimum Calls per Unit Hour were 5.6 on Thursday at the Squad B.
(4) Analyzing demand for EMTs in the optimum emergency medical service of Korea, we have been able to utilize this Unit Hour Utilization in company with the established estimation methods such as international comparisons or the number of ambulances for scientific·reasonable estimation.
(5) These Call Demands which were limited to the demand time in this study will make us expect some following studies including demand time, demand map for Strategic Deployment.
