Visits to a metropolitan teaching hospital emergency room were evaluated for laboratory test utilizaion and quality of care of chart review. Of 630 tests, 197 (32 per cent), clustered in 44 out of 476 (9 per cent) patient visits, were considered unnecessary. The number of tests per visit showed a strong negative correlation with the necessity of tests and with the quality of care. Results suggest the usefulness of identifying a subgroup of patients with excessive tests and implementing measures to alter testing behavior for this subgroup.
对一家大都市教学医院急诊室的就诊情况进行了评估,以了解实验室检查的使用情况和病历审查的护理质量。在630项检查中,197项(32%)集中在476次(9%)患者就诊中的44次就诊中,被认为是不必要的。每次就诊的检查数量与检查的必要性和护理质量呈强烈负相关。结果表明,识别出检查过多的患者亚组并对该亚组实施改变检查行为的措施是有用的。
