Case-mix systems for nursing homes use resident characteristics to predict the relative use of resources. Seven systems are compared in structure, accuracy in explaining resource use, group homogeneity, and ability to identify residents receiving heavy care. Resource utilization groups, version II (RUG-II), was almost uniformly the best system, although management minutes and the Minnesota case-mix system were also highly effective. Relative weights for case-mix groups were sensitive to cost differences and should be recomputed for new applications. Multiple criteria should be used in choosing a case-mix system, including consideration of inherent incentives and how residents' characteristics are defined.

养老院的病例组合系统利用居民特征来预测资源的相对使用情况。对七个系统在结构、解释资源使用的准确性、组内同质性以及识别接受重症护理居民的能力方面进行了比较。资源利用组第二版（RUG-II）几乎在各方面都是最佳系统，不过管理分钟数和明尼苏达病例组合系统也非常有效。病例组合组的相对权重对成本差异很敏感，在新的应用中应重新计算。选择病例组合系统时应使用多个标准，包括考虑内在激励因素以及居民特征的定义方式。
