A study was conducted on the use of radiographic studies by 138 medical residents. They ordered an initial chest film on 88% of their patients and averaged a 34% yield. Though the range of other radiographic studies ordered per patient varied by a factor of 15, more than half the resident physicians ordered an average of less than one for every two patients. These physicians experienced overall yields between 0 and 100%, with half the residents averaging between 33 and 57%. This data base was then used to derive empirical norms of radiographic study utilization that can be employed to evaluate physicians' utilization in providing care to comparable populations.
对138名住院医生使用放射学检查的情况进行了一项研究。他们为88%的患者开具了初始胸部X光片，平均阳性率为34%。尽管每位患者所开具的其他放射学检查项目数量相差15倍，但超过半数的住院医生平均每两名患者开具的检查项目不到一项。这些医生的总体阳性率在0%至100%之间，其中一半的住院医生平均阳性率在33%至57%之间。然后利用这个数据库得出放射学检查使用的经验性标准，可用于评估医生在为类似人群提供医疗服务时的检查使用情况。
