Аннотация
BACKGROUND: This systematic review aimed to assess the effectiveness of full personal protective equipment (PPE) in preventing COVID-19 transmission among health care workers.
METHODS: Studies published from December 2019 to August 2024 were searched in MEDLINE, Embase, Cochrane Library, CINAHL, Epistemonikos, ClinicalTrials.gov, MedRxiv, and Web of Science. Full PPE was defined as the combination of respiratory protection (surgical mask, N95, or equivalents), eye protection (visor or goggles), gown, and gloves, as recommended by the World Health Organization (WHO). The comparator was partial PPE or no PPE. Two reviewers independently performed screening, data extraction, and risk of bias assessment. The review was registered on PROSPERO (CRD4202230259).
RESULTS: Eight observational studies were included; 4 showed a significant reduction in transmission with full PPE. Seven studies compared full to partial PPE, and 1 compared full PPE to no protection. Among studies with significant results, odds ratios ranged from 0.03 to 0.6. Risk of bias was critical in 6 studies and serious in 2. No meta-analysis was performed due to study quality.
CONCLUSION: Full PPE appears protective for health care workers. The small number and low quality of studies limit the certainty of this conclusion. Further analyses are required to establish clear guideline for its use.
