Lot Quality Assurance Sampling (LQAS), developed to meet industrial quality control needs, has been applied to health surveys. The WHO used this method to assess immunization coverage. The sampling strategy was developed to classify lots as acceptable or unacceptable. Lot sampling is an efficient, simple and time-efficient procedure for quality assurance. Under certain conditions, efficiency can be improved with double sampling. We describe the method and its theoretical basis and illustrate applications of LQAS in epidemiological surveillance and quality control of medical records. The advantages and disadvantages of this method are presented.
批质量保证抽样法（LQAS）是为满足工业质量控制需求而开发的，现已应用于健康调查。世界卫生组织使用这种方法来评估免疫接种覆盖率。该抽样策略旨在将批次分类为可接受或不可接受。批抽样是一种高效、简单且省时的质量保证程序。在某些情况下，双重抽样可提高效率。我们描述了该方法及其理论基础，并举例说明了LQAS在流行病学监测和医疗记录质量控制中的应用。同时介绍了这种方法的优缺点。
