经常接触气雾剂产生程序的前线工作人员感染严重急性呼吸系统综合症冠状病毒2的风险特别高。我们的目标是评估现有N95/P2口罩为经常接触气雾剂产生程序的工作人员提供的呼吸保护是否足够。我们对配合度测试结果进行了前瞻性审计。纳入了麻醉和疼痛医学部工作人员的方便样本，他们选择接受N95/P2口罩的定性和/或定量适合性测试。配合度测试是按照标准指南进行的，包括配合度检查。我们记录了面罩的类型和大小、通过或失败以及适合性测试的持续时间。工作人员完成了一份关于之前N95/P2口罩培训的简短问卷，内容是关于通过适合性测试获得的信心和知识。使用该机构常规提供的N95/P2口罩的首次合格率仅为47%。通过测试不同类型和大小的口罩，合格率提高了。与适配测试前相比，适配测试后对可用面罩将提供足够适合性的置信度更高；(中位数，四分位数范围)五点利克特量表(4.0(4.0-5.0)比3.0(2.0-4.0)；P
Front-line staff routinely exposed to aerosol-generating procedures are at a particularly high risk of transmission of severe acute respiratory syndrome coronavirus 2. We aimed to assess the adequacy of respiratory protection provided by available N95/P2 masks to staff routinely exposed to aerosol-generating procedures. We performed a prospective audit of fit-testing results. A convenience sample of staff from the Department of Anaesthesia and Pain Medicine, who opted to undergo qualitative and/or quantitative fit-testing of N95/P2 masks was included. Fit-testing was performed following standard guidelines including a fit-check. We recorded the type and size of mask, pass or failure and duration of fit-testing. Staff completed a short questionnaire on previous N95/P2 mask training regarding confidence and knowledge gained through fit-testing. The first fit-pass rate using routinely available N95/P2 masks at this institution was only 47%. Fit-pass rates increased by testing different types and sizes of masks. Confidence 'that the available mask will provide adequate fit' was higher after fit-testing compared with before fit-testing; (median, interquartile range) five-point Likert-scale (4.0 (4.0-5.0) versus 3.0 (2.0-4.0); P
