Healthcare workers (HCWs) employed personal protective equipment (PPE) during the COVID-19 pandemic, crucial to protecting themselves from infection. To highlight the efficacy of PPE in preventing environmental infection among HCWs, a systematic review was conducted in line with PRISMA guidance.
A search of the PubMed and Web of Science databases was conducted from January 2019 to April 2021 using pre-defined search terms. Articles were screened by three researchers. The approved papers were read in full and included in this review if relevance was mutually agreed upon. Data were extracted by study design and types of PPEs.
47 of 108 identified studies met the inclusion criteria, with seven reviews and meta-analyses, seven cohort, nine case-control, fifteen cross-sectional studies, four before and after, four case series, and one modeling studies. Wearing PPE offered COVID-19 protection in HCWs but required adequate training. Wearing surgical masks provided improved protection over cloth masks, while the benefit of powered air-purifying respirators is less clear, as are individual gowns, gloves, and/or face shields.
Wearing PPE, especially facial masks, is necessary among HCWs, while training in proper use of PPE is also important to prevent COVID-19 infection.
医护人员（HCWs）在 COVID-19 大流行期间使用个人防护设备（PPE），这对于保护他们免受感染至关重要。为了强调 PPE 在预防医护人员环境感染方面的功效，我们按照 PRISMA 指南进行了系统评价。
我们使用预先定义的搜索词，对 PubMed 和 Web of Science 数据库进行了 2019 年 1 月至 2021 年 4 月的搜索。由三名研究人员对文章进行筛选。如果一致认为相关，则会阅读全文并纳入审查的文章。根据研究设计和 PPE 类型提取数据。
在确定的 108 篇文章中，有 47 篇符合纳入标准，其中包括 7 篇综述和荟萃分析、7 篇队列研究、9 篇病例对照研究、15 篇横断面研究、4 篇前后对照研究、4 篇病例系列研究和 1 篇建模研究。在医护人员中使用 PPE 可以提供 COVID-19 保护，但需要进行充分的培训。与布制口罩相比，外科口罩提供了更好的防护，而动力空气净化呼吸器的益处不太明确，个体长袍、手套和/或面罩也是如此。
医护人员有必要佩戴 PPE，尤其是面部口罩，而对 PPE 使用的正确培训也很重要，这可以预防 COVID-19 感染。
