Validation on the elimination of neonatal tetanus programs through Lot Quality Assurance-Cluster Sample Survey in China / 中华流行病学杂志

ABSTRACT

<p><b>OBJECTIVE</b>Field surveys were performed under WHO recommended validation procedures, using the Lot Quality Assurance-Cluster Sample(LQA-CS)method to validate the elimination status regarding neonatal tetanus in China.</p><p><b>METHODS</b>LQA-CS surveys were conducted in two areas under the highest risk of neonatal tetanus-Jiangmen prefecture in Guangdong and Hechi in Guangxi. Random sampling method was conducted on 96 survey clusters in each prefecture with 12 eligible live births(live birth born one year before the survey)for each cluster, by trained investigators.</p><p><b>RESULTS</b>There were 1 153 eligible live births from 23 465 families surveyed in Jiangmen and 1 152 eligible live births from 21 623 families being studied in Hechi. All the indices on quality control were strictly followed. There was no neonatal tetanus case which met the criteria of neonatal elimination found in either of the areas. Data showed that neonatal tetanus had been eliminated in both Jiangmen and Hechi cities.</p><p><b>CONCLUSION</b>Since both Jiangmen and Hechi were cities having the highest-risk in China, it was most likely that neonatal tetanus had also been eliminated in other prefectures at lower risk. Elimination programs on MNT was therefore considered validate in China when the study was carried out. However, the achievements needed to be maintained.</p>
