BACKGROUND
The COVID-19 pandemic has promoted a shortage of filtering facepiece respirators (FFRs) and the emergence of new FFRs brands. We aimed to determine the fit provided by in-use FFRs in Peruvian healthcare workers (HCWs) during the COVID-19 pandemic.
METHODS
We enrolled 279 HCWs from 37 primary healthcare centers with highest burden of care for TB in Peru, of which 263 were assessed using quantitative fit tests (QNFT). Results were expressed as real-time fit factor (rt-FF) and overall fit factor (overall-FF), which was categorized as ≥100 (optimal result), 50-99, and <50.
RESULTS
We identified 3M 1860 FFRs (33.1%), Xiantao Zhong Yi ZYB-11 FFRs (24.6%) and Makrite 9500 FFRs (20.5%), mainly. Eighty-seven FFRs (33.1%) had an optimal overall-FF, 27 (10.3%) between 50-99, and 149 (56.6%) less than 50. Of the 87 FFRs with optimal overall-FF, 73 (83.9%) were 3M 1860 FFRs. Of the 27 FFRs with overall-FF between 50-99, 7 (25.9%) were Makrite 9500, while of the 149 with overall-FF less than 50, 58 (38.9%), and 47 (31.5%) were Xiantao Zhong Yi ZYB-11 and Makrite 9500, respectively.
CONCLUSION
Xiantao Zhong Yi and Makrite FFRs do not adapt adequately to the face of Peruvian HCWs, most having fit factors less than 50.
背景
COVID-19 大流行导致过滤式面罩（FFR）短缺，并且出现了新的 FFR 品牌。我们旨在确定 COVID-19 大流行期间秘鲁医护人员（HCW）使用的 FFR 提供的适配情况。
方法
我们招募了来自秘鲁 37 个初级保健中心的 279 名 HCW，其中 263 名接受了定量 fit 测试（QNFT）评估。结果表示为实时 fit 因子（rt-FF）和整体 fit 因子（overall-FF），分为≥100（最佳结果）、50-99 和<50。
结果
我们发现 3M 1860 FFR（33.1%）、仙桃中一 ZYB-11 FFR（24.6%）和 Makrite 9500 FFR（20.5%）是主要的 FFR 品牌。87 个 FFR（33.1%）的整体 fit 因子最佳，27 个（10.3%）为 50-99，149 个（56.6%）小于 50。在 87 个整体 fit 因子最佳的 FFR 中，73 个（83.9%）是 3M 1860 FFR。在整体 fit 因子为 50-99 的 27 个 FFR 中，有 7 个（25.9%）是 Makrite 9500，而在整体 fit 因子小于 50 的 149 个 FFR 中，有 58 个（38.9%）和 47 个（31.5%）分别是仙桃中一 ZYB-11 和 Makrite 9500。
结论
仙桃中一和 Makrite FFR 不能很好地适应秘鲁 HCW 的面部特征，大多数的 fit 因子小于 50。
