改良批质量抽样检验在地方性氟中毒轻病区复核判定质量控制中的应用

目的 探讨改良批质量抽样检验方法在地方性氟中毒（简称地氟病）轻病区复核判定质量控制中的应用。方法 2009年在四川省叙永县15个地氟病轻病区乡（镇）中单纯随机抽取6个，采用改良批质量抽样检验对22所村小学8～ 12岁儿童氟斑牙患病情况进行复核判定。结果 在6个乡（镇）97个轻病区村中，共核查22个村，占22.68％,复查氟斑牙儿童416人，检出氟斑牙儿童383人，氟斑牙儿童复核吻合率达92.07％；核查质量判定轻病区村达21个，占95.45％。结论 改良批质量抽样检验在地氟病轻病区复核判定质量控制中的应用，能提高质量控制工作效率，提高轻病区复核判定准确率，是地氟病轻病区判定质量控制的一种新颖方法。

Application of a method of improving the quality of sampling in review to determine the light areas of endemic fluorosis in quality control

Objective To study an application of a method of improving the quality of sampling in review to determine the light areas of endemic fluorosis(referred to as endemic fluorosis) in quality control. Methods Of 15 light endemic fluorosis township(town), six were randomly sampled, and the prevalence of dental fluorosis in 22 village primary school children aged 8 to 12 were reviewed to determine the improved quality of sampling in Xuyong county Sichuan province. Results Six townships(towns) were selected by simple random sampling from 15 endemic fluorosis townships(towns) for review inspection in Xuyong country. A total of 22 villages were verified, accounting for 22.7％ of the total 97 villages verified. Of the 416 children for review inspection of dental fluorosis, 383 children were positive. The consistent rate of children' s dental fluorosis was 92.07％, and the verification to be slight villages was up to 21 endemic villages, accounting for 95.45％. Conclusions The application of a method of improving the quality of sampling can improve the efficiency of quality control, and improve the accuracy. It is a novel quality control method.
