EMERGENCY ADMISSIONS AND ELECTIVE SURGERY WAITING TIMES
利用澳大利亚新南威尔士州公立医院年度数据，研究发现急诊入院量增加会延长择期手术平均等待时间19天，但自费患者不受影响，甚至等待时间缩短，揭示了医疗资源分配中的公平性问题。
An average patient waits between 2 and 3 months for an elective procedure in Australian public hospitals. Approximately 60% of all admissions occur through an emergency department, and bed competition from emergency admission provides one path by which waiting times for elective procedures may be lengthened. In this article, we investigated the extent to which public hospital waiting times are affected by the volume of emergency admissions and whether there is a differential impact by elective patient payment status. The latter has equity implications if the potential health cost associated with delayed treatment falls on public patients with lower ability to pay. Using annual data from public hospitals in the state of New South Wales, we found that, for a given available bed capacity, a one standard deviation increase in a hospital's emergency admissions lengthens waiting times by 19 days on average. However, paying (private) patients experience no delay overall. In fact, for some procedures, higher levels of emergency admissions are associated with lower private patient waiting times.
