摘要
应用批质量保证抽样法（ＬｏｔＱｕａｌｉｔｙＡｓｓｕｒａｎｃｅＳａｍｐｌｉｎｇ，ＬＱＡｓ），对南昌市东湘区四个街道（相当于乡镇三级单位）的儿童计划免疫“四苗”覆盖率进行了现场调查。结果显示，各街道“四苗”覆盖率均达到８５％的水平，与按容量比例的概率抽样法（ＰｒｏｂａｂｉｌｉｔｙＰｒｏｐｏｒｔｉｏｎａｌｔｏＳｉｚｅ，ＰＰＳ）结果相比较，无显著性差异，表明ＬＱＡＳ法可代替ＰＰＳ法在三级单位进行儿童计划免疫工作评价，且经济、简便、快速、有效。
e have been using PPS(Puobability Proportional to
Size)method,as recommanded by WHO,toestimate the vaccine coverage
rate in provincial and county level.As for the residential districts,
be-cause of their small division and the reduced number of right age
children to be covered in vaccine eval-uation,PPS method is not very
applicable to residential district.We have tried to use LQAS(Lot
QuaL-ity Assurance Sampling)method to evaluate the coverage rate of
four vaccines(Measles, Polio,BCG,Pertussis diphtheria tetanus
mixture)used in four residential districts of Dong Hu District.The
re-sults showed that the immunization coverage rate of four
residential districts all reached 85%.Whencompared with that of PPS
method,there appeared no difference statistically.So PPS can be
replacedby LQAS in EPI estimating.LQAS is cheep,simple,rapid and
efficient.
