Due to meagre resources in terms of trained medical personnel and financial support and the absence of accurate population-based data in most parts of the developing world, there is an urgent need to develop new epidemiological study designs that are simple, accurate and easy to use. Key informant methodology and random cluster sample survey methods were used independently (a) to determine the prevalence of epilepsy and (b) to compare the efficiency, cost effectiveness and feasibility of the two survey methods. The random cluster method proved more scientifically valid and sensitive as compared to the key informant methods, which was found to be less accurate, although simple and easy to use, for example, by nonmedical workers in identifying epileptics.
由于发展中世界大部分地区训练有素的医务人员和财政支持资源匮乏，且缺乏基于准确人口的数据，因此迫切需要开发简单、准确且易于使用的新的流行病学研究设计。分别使用关键信息人方法和随机整群抽样调查方法：(a) 确定癫痫的患病率；(b) 比较两种调查方法的效率、成本效益和可行性。与关键信息人方法相比，随机整群方法被证明在科学上更有效且更敏感，后者虽简单易用，但不够准确，例如非医务人员在识别癫痫患者时就不够准确。
