To characterize the accuracy of clinician knowledge of anesthesia drug and equipment costs at one institution.
Anonymous survey instrument.
Large academic medical center.
130 questionnaires were sent to departmental practitioners, including residents, CRNAs, and attendings. An updated list of acquisition costs for commonly used drugs and equipment is posted on our departmental website and is sent to all clinical staff by electronic mail annually. For each item, the respondent was given a choice of price ranges and indicated the range in which they believed the actual cost of the item to be. Accuracy was calculated as the difference between the identifier of the correct and chosen ranges. The mean and variance of these differences were then calculated for each item within each practitioner group and tested to identify statistically significant differences among practitioner groups.
A total of 103 (79%) completed questionnaires were received. Many practitioners overestimated or underestimated the actual costs of most of the items. There was no significant difference between the groups for the mean accuracy across the entire set of items. For variance in price estimation, there was a statistically significant greater variance only for CA1 residents compared with attendings, CRNAs, and CA3 residents.
Many experienced practitioners in an academic setting lack accurate knowledge of the acquisition costs of common drugs and supplies.
描述一家机构的临床医生对麻醉药物和设备成本知识的准确性。
匿名调查工具。
大型学术医疗中心。
向包括住院医师、注册护士麻醉师和主治医生在内的科室医生发送了 130 份问卷。一份常用药物和设备采购成本的更新清单张贴在我们的科室网站上，并通过电子邮件每年发送给所有临床工作人员。对于每个项目，受访者可以选择价格范围，并指出他们认为该项目实际成本所在的范围。准确性的计算方法是正确和选择范围之间的差异标识符。然后计算每个医生组内每个项目的这些差异的平均值和方差，并进行测试以确定医生组之间是否存在统计学上的显著差异。
共收到 103 份（79%）完成的问卷。许多医生对大多数项目的实际成本高估或低估。整个项目组中，各医生组之间的平均准确性没有显著差异。对于价格估计的方差，只有 CA1 住院医师与主治医生、注册护士麻醉师和 CA3 住院医师相比，方差具有统计学意义。
在学术环境中，许多有经验的医生对常见药物和供应品的获取成本缺乏准确的知识。
