I sought to determine whether emergency department (ED) volume is associated with differing ED wait times.
I conducted a retrospective analysis of the Emergency Department Reporting System database of the Ontario Ministry of Health. I abstracted ED length of stay for patient visits to 117 hospital EDs during the second quarter of 2008, representing 89% of ED visits in the province during that period. Annual volume of ED visits, lengths of stay in the ED and acuity levels of patients were measured.
All EDs were more efficient in managing the treatment of low-acuity patients compared with high-acuity patients. Small rural EDs in Ontario had the shortest wait times for both high- and low-acuity patients (medians 2.35 h for high-acuity and 1.46 h for low-acuity patients in small rural EDs v. 4.98 h for high-acuity and 2.85 h for low-acuity patients in teaching hospitals).
Among the hospitals studied, rural EDs had the shortest wait times for both low- and high-acuity patients.
我试图确定急诊科（ED）的就诊量是否与不同的急诊科等待时间相关。
我对安大略省卫生部的急诊科报告系统数据库进行了回顾性分析。我提取了2008年第二季度117家医院急诊科患者就诊的急诊留观时长，这占该时期该省急诊就诊量的89%。测量了急诊科的年就诊量、急诊留观时长以及患者的 acuity 水平。
与高 acuity 患者相比，所有急诊科在处理低 acuity 患者的治疗方面效率更高。安大略省的小型农村急诊科对高 acuity 和低 acuity 患者的等待时间最短（小型农村急诊科高 acuity 患者的中位数为2.35小时，低 acuity 患者为1.46小时，而教学医院高 acuity 患者为4.98小时，低 acuity 患者为2.85小时）。
在所研究的医院中，农村急诊科对低 acuity 和高 acuity 患者的等待时间最短。
