摘要

摘要: 目的分析南京市托幼机构2019—2021年消毒质量现状及影响因素，为优化托幼机构预防性消毒的策略和措施提供科学依据。方法对南京市2019年1月—2021年12月389家托幼机构环境样本进行卫生学检测，比较消毒质量合格率的变化情况。结果 2019—2021年托幼机构总体消毒质量合格率分别为96.32%，95.85%和94.60%，呈逐年下降趋势(χ_趋势²=8.67，P < 0.05)，其中物体表面、工作人员手和餐(饮)具消毒质量合格率呈下降趋势，动态空气消毒质量合格率呈上升趋势，差异均有统计学意义(χ_趋势²值分别为23.17，12.32，5.37，21.48，P值均 < 0.05)。江宁和六合区消毒质量总合格率上升(χ_趋势²值分别为21.46，24.05，P值均 < 0.05)。结论南京市托幼机构消毒质量2019—2021年逐年下降，特别是物体表面和工作人员手项目。亟需优化并细化托幼机构预防性消毒的策略和措施，加强人员消毒知识培训，落实托幼机构消毒质量。

Abstract: Objective To analyze the disinfection quality and influencing factors of nurseries in Nanjing during 2019-2021, so as to provide a scientific basis for optimizing preventive disinfection strategies and measures in nurseries. Methods Environmental samples from 389 nurseries in Nanjing from January 2019 to December 2021 were tested, and the change of disinfection quality qualification rate was compared. Results The overall disinfection qualification rate of nurseries of year 2019-2021 were 96.32%, 95.85% and 94.60%, respectively, showing a downward trend (χ_trend²=8.67, P < 0.05). Specifically, disinfection qualification rate of object surfaces, staff hands and tableware showed a downward trend, while the disinfection qualification rate of dynamic air showed an upward trend, and the differences were statistically significant (χ_trend²=23.17, 12.32, 5.37, 21.48, P < 0.05). The total qualification rate of disinfection in Jiangning and Liuhe districts increased during 2019-2021(χ_trend²=21.46, 24.05, P < 0.05). Conclusion Disinfection quality of nurseries in Nanjing has declined by year during 2019-2021, especially the object surfaces and staff hands. It is urgent to optimize and refine the strategies and measures for preventive disinfection in nurseries, strengthen the training of personnel on disinfection knowledge, and ensure the quality of disinfection in nurseries.
