All hospital care can be characterized as either appropriate (i.e., efficatious and necessary) or inappropriate (i.e., services without benefit or services that could be provided in a less costly setting). A demonstration project combining an appropriateness determination methodology with a cybernetic control system was implemented in a study area that included six hospitals and approximately 400 practicing physicians. Project results to date indicate substantial improvements in the ratio of appropriate to inappropriate care for both hospitals and individual physicians. Evaluation research design problems and areas of future research are also discussed.
所有医院护理都可被界定为恰当的（即有效且必要的）或不恰当的（即无益处的服务或可在成本更低的环境中提供的服务）。在一个包括六家医院和约400名执业医师的研究区域实施了一个将恰当性判定方法与控制论控制系统相结合的示范项目。迄今为止的项目结果表明，医院和个体医师的恰当护理与不恰当护理之比都有显著改善。还讨论了评估研究设计问题及未来研究领域。
