A randomized controlled trial of several strategies designed to reduce the use of laboratory tests by house staff was performed in two parts. Part 1 compared cost education, cost audits, and both methods combined, all after a baseline observation period. Significant reductions were achieved only in the combination group for the categories of total tests (9.4%) and Sequential Multiple Analysis (SMA)-12 (10.8%), but not for charges, SMA-6, or complete blood cell counts (CBCs). Part 2 compared a group subjected to faculty chart review with a control group. Significant reductions in total charges (9.8%), total tests (15.1%), SMA-12s (20.6%), SMA-6s (12.5%), and CBCs (18.5%) were observed in the intervention group, as compared with the control group. Among the methods examined, faculty chart review seems to be the most effective method of reducing the amount of laboratory testing performed by house staff.
一项旨在减少住院医生实验室检查使用量的几种策略的随机对照试验分两部分进行。第一部分在基线观察期之后，比较了成本教育、成本审计以及两者结合的方法。仅在联合组中，总检查项目（9.4%）和连续多项分析（SMA）-12（10.8%）实现了显著减少，但费用、SMA-6或全血细胞计数（CBC）未实现显著减少。第二部分将接受教员病历审查的组与对照组进行了比较。与对照组相比，干预组的总费用（9.8%）、总检查项目（15.1%）、SMA-12（20.6%）、SMA-6（12.5%）和CBC（18.5%）均有显著减少。在所研究的方法中，教员病历审查似乎是减少住院医生进行的实验室检查量的最有效方法。
