【摘要】 目的 了解安徽省部分地区托幼机构工作人员和幼儿手卫生情况及其影响因素，为提高托幼机构的感染预防控制提供参考依据。方法 采用便利抽样法在安徽省北部和南部各选取1个市，每市选取3个县/区，每个县/区选取至少2～3家托幼机构，共22家托幼机构，对其工作人员和幼儿进行现场采样。使用χ~2检验分析工作人员、幼儿手卫生前后细菌总数合格率差异以及不同特征组间工作人员、幼儿手卫生效果合格率差异。结果 工作人员和幼儿手卫生后的细菌总数合格率均高于手卫生前(93.5%vs 80.9%，χ~2=15.199,P<0.001;87.9%vs 78.6%，χ~2=6.673,P=0.010)。托幼机构工作人员和幼儿手卫生合格率分别为30.2%和24.7%。洗手时长≥20 s的工作人员手卫生合格率高于洗手时长<20 s的工作人员(χ~2=5.673,P=0.017)，民办托幼机构、洗手时长≥20 s、有工作人员辅助的幼儿手卫生合格率均高于公办托幼机构、洗手时长<20 s、没有辅助的幼儿(P<0.05)。结论 安徽省部分地区托幼机构工作人员和幼儿的手细菌总数合格率较高，但手卫生效果不佳。更多还原

【Abstract】 Objective To understand the hand hygiene implementation and its influencing factors of the staff and children in kindergartens in some areas of Anhui province, and to provide reference for improving infection prevention and control in kindergartens. Methods The convenience sampling method was used to select one city each from the northern and southern parts of Anhui Province. In each city, three counties/districts were chosen, and at least two to three kindergartens were selected from each county/district. A total of 22 kindergartens were selected, and on-site sampling was conducted for their staff and children.The χ~2 tests were used to analyze the differences in the qualified rate of total hand bacteria count before and after hand hygiene among staff and children. Results The total bacterial count qualification rates after hand hygiene were higher than those before hand hygiene for both staff(93.5% vs. 80.9%, χ~2=15.199, P<0.001) and children(87.9% vs. 78.6%, χ~2=6.673, P=0.010). The overall hand hygiene compliance rates were 30.2% for staff and 24.7% for children. Staff who washed hands for ≥ 20 seconds had a higher compliance rate than those washing for <20 seconds(χ~2=5.673, P=0.017). Children in private institutions, those washing hands for ≥ 20 seconds, and those assisted by staff showed higher hand hygiene compliance rates compared to their counterparts in public institutions, those washing hands for <20 seconds, and those without assisted by staff(P<0.05). Conclusions The qualified rates of total hand bacteria count among staff and children in kindergarten in some areas of Anhui Province are relatively high, but the hand hygiene effects are not good in our study.更多还原
