OBJECTIVE
To study the impact of nurse-to-patient ratios on patient length of stay (LOS) in computer simulations of emergency department (ED) care.
METHODS
Multiple 24-hour computer simulations of emergency care were used to evaluate the impact of different minimum nurse-to-patient ratios related to ED LOS, which is composed of wait (arrival to bed placement) and bedtime (bed placement to leave bed).
RESULTS
Increasing the number of patients per nurse resulted in increased ED LOS. Mean bedtimes in minutes were impacted by nurse-to-patient ratios.
CONCLUSIONS
In computer simulation of ED care, increasing the number of patients per nurse resulted in increasing delays in care (ie, increasing bedtime).
目的
在急诊科护理的计算机模拟中研究护士与患者比例对患者住院时间（LOS）的影响。
方法
采用多次24小时的急诊护理计算机模拟，以评估与急诊科住院时间相关的不同最低护士与患者比例的影响，急诊科住院时间由等待时间（到达至床位安置）和卧床时间（床位安置至离床）组成。
结果
每名护士护理的患者数量增加导致急诊科住院时间延长。护士与患者比例对以分钟为单位的平均卧床时间有影响。
结论
在急诊科护理的计算机模拟中，每名护士护理的患者数量增加导致护理延迟增加（即卧床时间增加）。
