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.

UI	MeSH Term	Description	Entries
D011785	Quality Assurance, Health Care	Activities and programs intended to assure or improve the quality of care in either a defined medical setting or a program. The concept includes the assessment or evaluation of the quality of care; identification of problems or shortcomings in the delivery of care; designing activities to overcome these deficiencies; and follow-up monitoring to ensure effectiveness of corrective steps.

D003362	Cost-Benefit Analysis	A method of comparing the cost of a program with its expected benefits in dollars (or other currency). The benefit-to-cost ratio is a measure of total return expected per unit of money spent. This analysis generally excludes consideration of factors that are not measured ultimately in economic terms. In contrast a cost effectiveness in general compares cost with qualitative outcomes.
