BACKGROUND
Quantitative mask fit testing (QNFT) is the gold standard to confirm the correct fit of a N95/P2 mask to ensure health care workers protection from airborne viruses. Using the Occupational Safety and Health Administration (OSHA) guidance indicates a final fit test result is a cumulative score derived from manoeuvres within the OSHA protocol. The protocol-based manoeuvres mimic aspects of clinical care by health professionals and mask fit testing is conducted to provide protection from airborne viruses and pollutants within a care setting.
OBJECTIVES
To determine whether studies undertaking QNFT report the results of individual manoeuvres of the OSHA protocol.
METHODS
A comprehensive search strategy for the systematic review was developed to determine eligible studies, published between May 2011 and May 2021. Two researchers independently screened all full text articles retrieved and all disagreements were resolved through discussion.
RESULTS
The search found 557 studies. After removing 119 duplicates, 437 articles were reviewed based on title and abstract, 411 studies were excluded. Twenty-seven full text articles were assessed for eligibility, all were excluded for the following reasons: study did not report the results of the long or short OSHA protocol (12), study did not assess mask fit using the long or short OSHA protocol (10), article type (discussion/commentary/editorial) or wrong study type (1). Despite the use of very broad search terms no eligible studies were found and the result was declared an empty review.
CONCLUSION
Internationally accepted QNFT protocols have a number of manoeuvres that reflect health care workers' physical movements during the delivery of clinical care. Studies of mask fit testing appear to lack the reporting of outcomes for each manoeuvre with only the cumulative results being provided. This finding raises the need to understand potential risk from a mask leak during the delivery of clinical care as evidenced by failing a manoeuvre during mask fit testing. Further research is required to understand the importance of passing each mask fit testing manoeuvre and the relationship to airborne protection during the delivery of clinical care.
背景
定量面罩适合性测试（QNFT）是确认N95/P2口罩正确贴合度的金标准，以确保医护人员免受空气传播病毒的侵害。使用美国职业安全与健康管理局（OSHA）的指南表明，最终的适合性测试结果是根据OSHA协议中的操作得出的累积分数。基于协议的操作模拟了医疗专业人员在临床护理中的各个方面，进行面罩适合性测试是为了在护理环境中提供免受空气传播病毒和污染物侵害的保护。
目的
确定进行QNFT的研究是否报告了OSHA协议中各个操作的结果。
方法
制定了全面的搜索策略以进行系统评价，以确定2011年5月至2021年5月期间发表的符合条件的研究。两名研究人员独立筛选所有检索到的全文文章，所有分歧均通过讨论解决。
结果
搜索发现557项研究。去除119篇重复文章后，基于标题和摘要对437篇文章进行了审查，排除了411项研究。对27篇全文文章进行了资格评估，所有文章均因以下原因被排除：研究未报告长期或短期OSHA协议的结果（12篇），研究未使用长期或短期OSHA协议评估面罩贴合度（10篇），文章类型（讨论/评论/社论）或错误的研究类型（1篇）。尽管使用了非常宽泛的搜索词，但未找到符合条件的研究，结果宣布为无效评价。
结论
国际认可的QNFT协议有许多操作，反映了医护人员在提供临床护理期间的身体动作。面罩适合性测试的研究似乎缺乏对每个操作结果的报告，仅提供了累积结果。这一发现凸显了有必要了解在临床护理过程中因面罩泄漏而产生的潜在风险，如在面罩适合性测试中某个操作失败所证明的那样。需要进一步研究以了解通过每个面罩适合性测试操作的重要性以及与临床护理期间空气传播防护的关系。
