A decision tree priority dispatch system for emergency medical services (EMS) was developed and implemented in Atlanta and Fulton County, Georgia. The dispatch system shortened the average response time from 14.2 minutes to 10.4 minutes for the 30% of patients deemed most urgent (P less than or equal to .05); resulted in a significant increase in the use of advanced life support units for this group (P less than or equal to .02); decreased the number of calls that required a backup ambulance service; and significantly increased conformity to national EMS response time standards for critically ill and injured patients (P less than or equal to .0009). Due to dispatch error, 0.3% of calls were dispatched as least severe but subsequently were found to be most urgent.
一种用于紧急医疗服务（EMS）的决策树优先调度系统在佐治亚州的亚特兰大和富尔顿县开发并实施。对于30%被认为最紧急的患者（P≤0.05），该调度系统将平均响应时间从14.2分钟缩短至10.4分钟；该组使用高级生命支持设备的情况显著增加（P≤0.02）；需要后备救护车服务的呼叫数量减少；并且重症和受伤患者对国家EMS响应时间标准的符合度显著提高（P≤0.0009）。由于调度错误，0.3%的呼叫被调度为最不严重，但随后被发现是最紧急的。
