This article outlines a broad theoretical approach to measuring real cost-per-case differences resulting from differences in case mix, service intensity, and input productivity. Modifying the method in the interests of accommodating current lack of access to hospital data pertaining to diagnostic case mix, the authors apply the method to data from three Connecticut hospitals for the 1960-69 period and find both nominal and real changes in cost per case due to changes in factor input prices, gross service intensity, and factor input productivity.
本文概述了一种广泛的理论方法,用于衡量因病例组合、服务强度和投入生产率差异而导致的每病例实际成本差异。为了适应目前无法获取与诊断病例组合相关的医院数据的情况,作者对该方法进行了修改,并将其应用于康涅狄格州三家医院1960 - 1969年期间的数据,发现由于要素投入价格、总服务强度和要素投入生产率的变化,每病例成本出现了名义和实际的变化。
