The reports of hospital utilization review (UR) studies that appear in this issue employ a range of design strategies, and much of the variation seems accidental--arising because there are many acceptable strategies--rather than functional. This paper is about general design strategy: the value of explicit protocols for sampling and data collection, of analyses appropriate to the sampling, of generating reports managers can use. More coordination is strongly encouraged, to reduce unnecessary variation and to facilitate comparisons across studies. While individual groups may still opt for different strategies, techniques for increasing the comparability of reported findings are discussed. This will increase the value of each study, individually, as well as the value of the collective effort.
本期出现的医院利用情况审查（UR）研究报告采用了一系列设计策略，其中许多差异似乎是偶然的——是因为存在许多可接受的策略而产生的——而非功能性的。本文探讨的是一般设计策略：抽样和数据收集明确方案的价值、适合抽样的分析方法的价值、生成管理人员可用报告的价值。强烈鼓励加强协调，以减少不必要的差异，并便于各项研究之间进行比较。虽然各个小组可能仍会选择不同的策略，但本文讨论了提高报告结果可比性的技术。这将增加每项研究的单独价值，以及集体努力的价值。
