新型冠状病毒肺炎隔离病房医务人员防护用品使用现况多中心调查分析

Multicenter investigation of current status of use of personal protective equipment among healthcare workers during diagnosis and treatment of COVID-19

目的调查多中心新型冠状病毒肺炎(简称新冠肺炎)隔离病房中医务人员防护用品使用情况,了解其防护现状与特点。方法由经培训的医院感染管理专职人员随机抽取30所医院及院区的援鄂医疗队医务人员,记录被调查者基本情况和防护用品选择及穿戴的情况,并通过问卷星填报。结果此次调查发现参与新冠肺炎诊疗工作的医务人员在进入隔离病房前均接受防护用品使用及其穿脱流程的理论及实操培训,95.56%(2433人)的医务人员在穿脱防护用品时有专人检查或督导。86.57%(2204人)选择同时佩戴两层口罩,其中选择同时佩戴医用外科口罩及医用防护口罩的医务人员最多(1621人,63.67%,);57.50%(1464人)的医务人员使用护目镜或防护面屏,42.50%(1082人)同时使用护目镜及防护面屏;95.25%(2425人)的医务人员同时穿医用防护服及一次性隔离衣;96.62%(2460人)的医务人员同时穿靴套及鞋套;戴两层帽子的医务人员比例最高,占70.54%;戴双层手套的医务人员比例亦最高,占57.31%。结论此次援鄂医疗队医务人员的个人防护有效地预防了新冠肺炎感染,实现了4.26万援鄂医疗队员的"零感染"。但部分防护用品仍存在叠穿或叠加使用的现象,如何适度使用个人防护用品有待规范和探索。
