      【摘要】 目的 了解上海市虹口区2018—2023年养老机构的消毒质量，为提升养老机构内卫生消毒工作提供依据。方法 选择虹口区辖区内36家养老机构作为监测点，2018—2023年共开展65次检测，采集室内空气、环境物表、餐饮具和工作人员手4类样品开展菌落总数和大肠菌群检测，以此评估养老机构的消毒质量。结果 2018—2023年虹口区养老机构总体合格率为 90.11%，2018—2023年的合格率分别为 88.43%、89.16%、94.83%、98.05%、88.46%、81.82%，其中2021年合格率最高，不同年份样品检测合格率比较差异有显著统计学意义(P<0.01)。在新冠疫情爆发前(2018—2019年)消毒监测总体合格率为88.83%，新冠疫情期间的2020年监测合格率为94.83%，2021年监测合格率高达98.05%，新冠疫情后(2022—2023年)总合格率为83.89%，新冠疫情前后养老机构消毒质量监测结果比较差异有显著统计学意义(P<0.01)。室内空气、环境物表、餐饮具和工作人员手4类样品菌落总数合格率比较差异有统计学意义(P<0.05)，且室内空气的总体合格率最高，为100.00%，工作人员手合格率最低，为77.18%，但4类样品的大肠杆菌合格率比较差异无统计学意义(P>0.05)。结论 虹口区养老机构消毒工作尚存在不足，需进一步加强工作人员的手卫生清洁消毒工作。

【Abstract】 Objective To understand the disinfection quality of elderly care institutions in Hongkou District ofShanghai from 2018 to 2023, and to provide a basis for improving hygiene and disinfection work within these institu-tions. Methods Thirty-six elderly care institutions in Hongkou District were selected as monitoring points, and 65 in-spections were conducted from 2018 to 2023. Four types of samples, including indoor air, environmental surfaces, cater-ing utensils, and staff hands, were collected for total bacterial count and coliform detection to assess the disinfection qual-ity of the elderly care institutions. Results The overall qualification rate of elderly care institutions in Hongkou Districtfrom 2018 to 2023 was 90.11%, with qualification rate of 88.43% in 2018, 89.16% in 2019, 94.83% in 2020, 98.05% in2021, 88.46% in 2022, and 81.82% in 2023. The qualification rate in 2021 was the highest, and there was a statisticallysignificant difference in the qualification rates of samples tested in different years (P<0.01). Before the outbreak of COV-ID-19 (2018—2019), the overall qualification rate for disinfection monitoring was 88.83%. During the COVID-19 pan-demic, the qualification rate was 94.83% in 2020, and it reached 98.05% in 2021. After the COVID-19 pandemic(2022—2023), the overall qualification rate was 83.89%. There was a statistically significant difference in the monitor-ing results of disinfection quality in elderly care institutions before and after the COVID-19 pandemic (P<0.01). Therewere statistically significant differences in the qualification rates of total bacterial counts among the four types of sam-ples: indoor air, environmental surfaces, catering utensils, and staff hands (P<0.05). The overall qualification rate of in-door air was the highest, reaching 100.00%, while the qualification rate of staff hands was the lowest, at 77.18%. Howev-er, there was no statistically significant difference in the qualification rates of coliforms among the four types of samples(P>0.05). Conclusion There are still deficiencies in the disinfection work of elderly care institutions in Hongkou Dis-trict, and it is necessary to further strengthen the hand hygiene and disinfection work of staff.
