Focused utilization review efforts to date have centered on patient categories, i.e., diagnosis, service, or classification. Since the patient's length of stay is mostly controlled by the attending practitioner, it seemed logical to use practitioner profiles to focus review. The profiles developed compare each practitioner's patients, case-mix-adjusted, using diagnosis-related groups, to statewide length-of-stay norms. Standards (range of acceptable variations from the norm) can be adjusted to increase or decrease the impact of the review. After experience, standards were set that resulted in a significant decrease in the average length of stay and a resultant significant drop in patient days.
迄今为止，重点利用情况审查工作主要集中在患者类别上，即诊断、服务或分类。由于患者的住院时间大多由主治医生控制，因此使用医生资料来集中审查似乎是合乎逻辑的。所制定的资料使用诊断相关组，将每位医生的患者与全州住院时间规范进行病例组合调整后的比较。可以调整标准（与规范可接受的差异范围）以增加或减少审查的影响。经过实践，制定了相应标准，结果平均住院时间大幅减少，患者住院天数也随之显著下降。
