This paper offers a critical appraisal of the various methods used to date to investigate inequity in the delivery of health care. It concludes that none of the methods used to date is particularly well equipped to provide unbiassed estimates of the extent of inequity. It also concludes that Le Grand's (1978) approach is likely to point towards inequity favouring the rich even when none exists. The paper offers an alternative approach, which builds on the approaches to date but seeks to overcome their deficiencies.
本文对迄今为止用于调查医疗保健服务不公平性的各种方法进行了批判性评估。结论是，迄今为止所使用的方法中，没有一种特别适合提供关于不公平程度的无偏估计。还得出结论，即使不存在不公平现象，勒格兰德（1978年）的方法也可能指向有利于富人的不公平。本文提供了一种替代方法，该方法在现有方法的基础上构建，但试图克服它们的缺陷。
