A survey of emergency department visits was conducted over a 56-week period between November 1980 and November 1981. Inappropriate ambulance use and unmet ambulance need were compared between two cities (one large and one small) with paramedic ambulance services and two cities (one large and one small) with nonparamedic ambulance services. A total of 6,405 visits was evaluated, resulting in overall rates of inappropriate use and unmet need of 42% and 58%, respectively. When paramedic ambulance services were compared to nonparamedic services, the results indicated less inappropriate use in cities with paramedic services (34% vs 49%, P less than .001) as well as less unmet need in cities with paramedic services (48% vs 67%, P less than .001). These results remain consistent within most sample subgroups based on age, sex, time of arrival at ED, and disposition, except that no differences were found for small cities or for patients 50 years and older. The results indicate that paramedic ambulance systems are beneficial to the general population of emergency department users.
在1980年11月至1981年11月的56周期间，对急诊就诊情况进行了一项调查。比较了配备护理人员救护车服务的两个城市（一大一小）和配备非护理人员救护车服务的两个城市（一大一小）中救护车使用不当和未满足的救护车需求情况。共评估了6405次就诊，结果显示使用不当和需求未满足的总体发生率分别为42%和58%。将护理人员救护车服务与非护理人员服务进行比较时，结果表明配备护理人员服务的城市中使用不当的情况较少（34%对49%，P<0.001），配备护理人员服务的城市中需求未满足的情况也较少（48%对67%，P<0.001）。基于年龄、性别、到达急诊室的时间和处置情况，这些结果在大多数样本亚组中保持一致，但小城市或50岁及以上患者未发现差异。结果表明，护理人员救护车系统对急诊患者的总体人群有益。
