背景:在呼吸道感染大流行期间,口罩和呼吸器备受追捧,特别是一线医护人员和携带呼吸道病毒的患者。这项研究的目的是系统地审查拟合测试通过率,并确定影响拟合特征的因素。
方法:使用PubMed确定了潜在的相关研究,Scopus,WebofScience,在2020年2月5日至2023年3月21日的COVID-19大流行期间,和ScienceDirect。使用以下关键字进行了搜索策略:定量拟合测试,冷凝核计数器,受控负压,PortaCount,西巴塔,Accufit,适合,密封,面具,呼吸器,呼吸保护装置,呼吸防护设备,保护装置,个人防护设备,COVID-19,冠状病毒,和SARS-CoV-2.纳入研究的质量也使用纽卡斯尔-渥太华量表进行评估。
结果:共有137篇文章符合资格标准。50篇文章的质量得分小于7(质量良好)。共有21项研究的拟合测试通过率低于50%。26项关于一次性呼吸器的研究和11项关于可重复使用呼吸器的研究的FF分别小于50和小于200。影响最大的因素包括呼吸器品牌/型号、风格,性别,种族,面部尺寸,面部毛发,年龄,重用,广泛的运动,密封检查,舒适性和可用性评估,和训练。
结论:37.36%的一次性呼吸器研究和43%的可重复使用呼吸器研究未报告配合测试结果。67.86%的一次性呼吸器研究的配合测试通过率大于50%,这些研究中有35.84%的FF大于100。此外,85.71%的可重复使用的呼吸器研究的配合测试通过率大于50%,这些研究中有52.77%的FF大于1000。总的来说,拟合测试通过率相对可以接受.新开发或改进的呼吸器必须经过可靠的测试,以确保对HCWs的保护。实施配合测试方案时,应考虑受试者和呼吸器的特征。在呼吸器设计之前,应开发最佳配合测试面板。认证,采购决策,和选择程序。
During respiratory infection pandemics, masks and respirators are highly sought after, especially for frontline healthcare workers and patients carrying respiratory viruses. The objective of this study was to systematically
review fit test pass rates and identify factors influencing the fitting characteristics.
Potentially relevant studies were identified using PubMed, Scopus, Web of Science, and Science Direct during the COVID-19 pandemic from February 5, 2020, to March 21, 2023. The search strategy using the following keywords was conducted: Quantitative Fit Test, Condensation Nuclei Counter, Controlled Negative Pressure, PortaCount, Sibata, Accufit, Fit, Seal, Mask, Respirator, Respiratory Protective Device, Respiratory Protective Equipment, Protective Device, Personal Protective Equipment, COVID-19, Coronavirus, and SARS-CoV-2. The quality of the included studies was also assessed using the Newcastle-Ottawa scale.
A total of 137 articles met the eligibility criteria. Fifty articles had a quality score of less than 7 (good quality). A total of 21 studies had a fit test pass rate of less than 50%. 26 studies on disposable respirators and 11 studies on reusable respirators had an FF of less than 50 and less than 200, respectively. The most influential factors include respirator brand/model, style, gender, ethnicity, facial dimensions, facial hair, age, reuse, extensive movement, seal check, comfort and usability assessment, and training.
37.36% of the disposable respirator studies and 43% of the reusable respirator studies did not report fit test results. 67.86% of the disposable respirator studies had a fit test pass rate greater than 50%, and 35.84% of these studies had an FF greater than 100. Also, 85.71% of the reusable respirator studies had a fit test pass rate greater than 50%, and 52.77% of these studies had an FF greater than 1000. Overall, the fit test pass rate was relatively acceptable. Newly developed or modified respirators must undergo reliable testing to ensure the protection of HCWs. Subject and respirator characteristics should be considered when implementing fit testing protocols. An optimal fit test panel should be developed prior to respirator design, certification, procurement decisions, and selection procedures.
