Quality monitoring analysis of disinfection effectiveness in medical institutions in Shenzhen, 2015-2019

Objective To master the disinfection effect of medical institutions at different levels in Shenzhen, and we provide scientific basis for improving the quality of disinfection and reducing hospital-acquired infections. Methods According to the relevant standards, the quality of disinfection in medical institutions in Shenzhen city from 2015 to 2019 was continuously monitored by filed sampling and experimental testing. Results From 2015 to 2019, a total of 139 025 samples were collected form medical institutions in Shenzhen, of which 133 714 samples were qualified, and the qualified rate was 96.18%. The qualified rates for disinfection in 2015-2019 were 96.34%, 95.06%, 95.78%, 96.06%, 97.64%, respectively. The qualified rate increased year by year from 2016, and the difference was statistically significant ( P <0.001). Among all the monitoring items, the qualified rate of therapeutic water was the highest at 100.00%. The qualified rate ultraviolet lamp was the lowest at 91.75%. The qualified rate of private and individual clinics was 95.40%, which was lower than that of primary (98.48%), secondary (98.17%) and tertiary (97.84%) medical institutions ( P <0.05). Conclusion The overall quality of disinfection in medical institutions in Shenzhen is good, but the qualified rate of air, sanitary hand and ultraviolet lamp is low, and qualified rate of disinfection in private and individual clinics varies considerably over a five-year period, requiring further strengthening of supervision and management. 摘要：目的 掌握深圳市各级医疗机构消毒效果,为提髙消毒质量,减少院内感染提供科学依据。 方法 依据相 关标准,通过现场采样和微生物检验方法,对深圳市2015—2019年医疗机构消毒质量进行连续监测。 结果 深圳市 2015—2019年医疗机构共采样139 025件,合格样品133 714件,合格率96.18%。2015—2019年消毒合格率分别为 96.34%、95.06%、95.78%、96.06%、97.64%,从2016年开始合格率逐年上升,差异有统计学意义( P <0.001)。各监测项目 中,治疗用水合格率最髙,为100.00%;紫外线灯合格率最低,为91.75%。私营医疗机构及个体诊所合格率为95.40%, 三级医疗机构消毒合格率为97.84%、二级为98.17%,一级为98.48%,不同级别医疗机构消毒合格率差异有统计学意义 ( P <0.05)。其中,三级医疗机构手卫生和消毒后内镜消毒合格率偏低,私营及个体诊所空气和手卫生消毒合格率最低。 结论 深圳市医疗机构消毒质量整体较好,但空气、手卫生、紫外线灯消毒合格率较低,私营及个体诊所5年内消毒合 格率变化幅度较大,需要进一步加强监督管理。
