TI  - Lot quality assurance sampling techniques in health surveys in developing 
      countries: advantages and current constraints.
PG  - 133-9
AB  - Traditional survey methods, which are generally costly and time-consuming, 
      usually provide information at the regional or national level only. The 
      utilization of lot quality assurance sampling (LQAS) methodology, developed in 
      industry for quality control, makes it possible to use small sample sizes when 
      conducting surveys in small geographical or population-based areas (lots). This 
      article describes the practical use of LQAS for conducting health surveys to 
      monitor health programmes in developing countries. Following a brief description 
      of the method, the article explains how to build a sample frame and conduct the 
      sampling to apply LQAS under field conditions. A detailed description of the 
      procedure for selecting a sampling unit to monitor the health programme and a 
      sample size is given. The sampling schemes utilizing LQAS applicable to health 
      surveys, such as simple- and double-sampling schemes, are discussed. The 
      interpretation of the survey results and the planning of subsequent rounds of 
      LQAS surveys are also discussed. When describing the applicability of LQAS in 
      health surveys in developing countries, the article considers current limitations 
      for its use by health planners in charge of health programmes, and suggests ways 
      to overcome these limitations through future research. It is hoped that with 
      increasing attention being given to industrial sampling plans in general, and 
      LQAS in particular, their utilization to monitor health programmes will provide 
      health planners in developing countries with powerful techniques to help them 
      achieve their health programme targets.

OAB - Costly, time-consuming, traditional survey methods usually provide information 
      only at national or regional levels. Information from the health center and 
      community levels is, however, also of interest particularly in managing and 
      directing supervisory activities. An industrial method is described with 
      practical applications for conducting health surveys to monitor health programs 
      in developing countries. This lot quality assurance sampling (LQAS) methodology 
      was developed in industry for quality control, and allows the use of small sample 
      sizes when surveying small geographical or population-based areas. The paper 
      describes the method, explains how to build a sample frame, and how to conduct 
      the sampling necessary for field application of LQAS. Sampling unit selection for 
      health program monitoring is described in detail. Simple- and double-sampling 
      schemes are discussed, as well as interpretation of survey results and the 
      planning of subsequent rounds. Constraints limiting use by health planners are 
      explored with suggestions provided on modes of overcoming obstacles through 
      future research.
