【摘要】 目的 了解新型冠状病毒（以下简称“新冠病毒”）感染疫情发生前后浙江省医院消毒效果。方法 采用回顾性调查方法，对新冠病毒感染疫情发生前后该省3家医院的消毒质量监测结果资料进行统计分析，比较消毒合格率差异。结果 新冠病毒感染疫情发生前的2017—2019年共监测1 931份样本，总合格率为86.74%；疫情发生后的2020—2022年共监测1 850份样本，总合格率为93.14%，合格率高于疫情前（χ~2=42.411,P<0.001）。按季度监测结果显示，疫情发生后第一、四季度和第二、三季度消毒效果的总合格率均高于疫情前同期水平（92.40%vs 89.02%,93.84%vs 84.24%；χ~2=6.430和44.193,P<0.05）。相较于疫情发生前，疫情发生后医疗用水卫生质量和内镜消毒合格率明显上升（98.04%vs 63.31%,100.00%vs 96.26%；χ~2=138.499和5.430,P<0.05）。结论 新冠病毒感染疫情发生后医院消毒合格率明显提升，但仍要关注洁净手术室、手卫生和医院污水等消毒薄弱环节。更多还原

【Abstract】 Objective To investigate disinfection effect of hospitals in Zhejiang province before and during the COVID-19epidemic.Methods Retrospective investigation method was used to statistically analyze the monitoring results of disinfection effect of three hospitals in the province before and during the COVID-19 epidemic,and compare the difference of disinfection qualified rate.Results A total of 1 931 samples were monitored from 2017 to 2019 before the COVID-19epidemic,with the total qualified rate of disinfection of 86.74%.A total of 1 850 samples were monitored from 2020 to 2022during the COVID-19 epidemic,with the total qualified rate of disinfection of 93.14%,which was significantly higher than that before the pandemic (χ~2=42.411,P<0.01).Quarterly monitoring results showed that total qualified rate of disinfection effect in every quarter after the outbreak was higher than the level in the same period before the outbreak (92.40%vs89.02%,93.84%vs 84.24%;χ~2=6.430 and 44.193,P<0.05).Compared with before the COVID-19 pandemic,the qualified rate of medical water and endoscope disinfection increased significantly during the pandemic (98.04%vs 63.31%,100.00%vs 96.26%;χ~2=138.499 and 5.430,P<0.05).Conclusion The qualified rate of hospital disinfection has improved significantly since the COVID-19 outbreak,but the vulnerable spots of the disinfectant work such as operating room,hand hygiene and hospital sewage need to be strengthened.更多还原
