某院新型冠状病毒肺炎疫情常态化防控阶段医院感染量化考核方法及效果

Effect of quantitative assessment of nosocomial infection management in normalized prevention and control phase of the COVID-19pneumonia epidemic

目的运用量化考核评估新冠疫情常态化防控措施落实情况,评价疫情防控效果和对医院感染管理质量的影响。方法对华中科技大学同济医学院附属同济医院感控措施进行归纳,并细化为16项量化考核指标,于2020年7-12月进行全院巡查考核。收集同期疫情防控数据、医院感染发病率、手卫生相关数据。结果未发现新冠肺炎确诊病例,未发现无症状感染者传染他人情况。2020年7-12月医院感染发病例次率较2019年同期下降,分层分析显示主要是上呼吸道、泌尿道及胃肠道感染明显减少,而Ⅰ类切口手术部位感染率、血管内导管相关血流感染发病率、呼吸机相关肺炎发病率和导尿管相关泌尿系感染发病率均无明显变化。手卫生依从性、手卫生正确性和手消毒剂消耗量达标率明显提升,而干手纸巾和洗手液消耗量未见明显变化。结论量化考核可有效评估疫情常态化防控措施的落实情况,及时发现、排除潜在疫情隐患,同时对医院感染管理质量的提升有积极影响。

OBJECTIVE To evaluate the implementation of normalization prevention and control measures for the COVID-2019epidemic by quantitative assessment,and to evaluated the effectiveness of epidemic prevention and control and its impact on the quality of nosocomial infection management.METHODS The infection control measures of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology were summarized and refined them into 16quantitative assessment indicators,which will be inspected and assessed throughout the hospital from from Jul.to Dec.2020.Data on epidemic prevention and control,incidence of nosocomial infection,hand hygiene related data during the same period were collected.RESULTS No confirmed cases of novel coronavirus pneumonia were found,and no asymptomatic infection cases were found to infect others.The incidence of nosocomial infection from July to December 2020decreased compared with the same period in 2019.Stratified analysis showed that the infection of upper respiratory tract,urinary tract and gastrointestinal tract were significantly reduced,while there was no significant change in the infection rate of the type I incision surgical sites,the incidence of intravascular catheter related bloodstream infection,the incidence of ventilator-associated pneumonia and the incidence of catheter-related urinary tract infection.The compliance of hand hygiene,the accuracy of hand hygiene and the standard rate of hand disinfectant consumption were significantly improved,while there was no significant change in the consumption of dry hand tissue and hand sanitizer.CONCLUSIONQuantitative assessment can effectively evaluate the implementation of normalized prevention and control measures of epidemic situation.The timely detection and elimination of potential epidemic hazards will have a positive impact on the improvement of the quality of nosocomial infection management.
