全国囊虫病、包虫病血清流行病学调查质量评价

EVALUATION ON THE QUALITY OF SEROEPIDEMIOLOGICAL SURVEY FOR CYSTICERCOSIS AND HYDATIDOSIS IN CHINA

目的 对全国囊虫病、包虫病血清流行病学调查质量进行评价。 方法 用相同试剂盒 ,按统一的操作规范 ,对各地检测出全部阳性血清和随机抽取的部分阴性血清进行复测 ,并采用符合率和Kappa统计量评价两次检测结果的一致性。 结果 囊虫病、包虫病两次检测结果阳性符合率分别为 5 8.5 4%和 91.12 % ,阴性符合率分别为 98.83 %和96.5 8% ,总符合率分别为 98.85 %和 97.47%。Kappa值分别为 0 .713 9和 0 .93 62。囊虫病二次检测重现性好 ,包虫病二次检测重现性极好。Kappa统计量分析回代结果一致性都具有极显著性意义 (P <0 .0 1)。 结论 本次囊虫病和包虫病血清流行病学调查质量控制较为理想。

Objective To evaluate the quality of seroepidemiological survey for cysticercosis and hydatidosis in China. W Methods To re test the total positive samples and part of negative samples by means of random sampling, following the same procedures in this survey, and then to evaluate the agreement of two tests with lonsistency and Kappa value. W Results Two tests showed that the positive agreement rate were 58.54% and 91.12%; the negative agreement rate were 98.83% and 96.58%; total agreement rate were 98.85% and 97.47%; Kappa value were 0.7139 and 0.9362. The reproducibility of cysticercosis was good and the reproducibility of hydatidosis was excellent. The lonsistency (identity) of results of Kappa test had significant difference. WConclusion The quality control was good in seroepidemiological survey for cysticercosis and hydatidosis.
