Impact of personal protective equipment use on health care workers’ physical health during the COVID-19 pandemic: a systematic review and meta-analysis
Abstract
Background
During the COVID-19 pandemic, health care workers (HCWs) caring for patients with coronavirus disease 2019 (COVID-19) in high-risk clinical settings have been obliged to wear personal protective equipment (PPE).
Aim
To assess the impact of PPE use on HCWs’ physical health during the COVID-19 pandemic. Also, we examined factors related with a greater risk of adverse events among HCWs due to PPE use.
Methods
We applied the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines and the Cochrane criteria for this systematic review and meta-analysis. We searched PubMed, Medline, Scopus, ProQuest, CINAHL and pre-print services (medRxiv) from January 1, 2020 to December 27, 2020.
Findings
Our review included 14 studies with 11,746 HCWs from 16 countries. The estimated overall prevalence of adverse events among HCWs was 78% (95% CI: 66.7-87.5%) with a range from 42.8% to 95.1% among studies. The prevalence of adverse events was higher for the studies with poor quality compared to those with moderate quality (83.5% vs. 67.1%), while increased sample size was related with decreased prevalence (p<0.001). The most frequent adverse events were headache (55.9%), dry skin (54.4%), dyspnoea (53.4%), pressure injuries (40.4%), itching (39.8%), hyperhidrosis (38.5%), and dermatitis (31.0%). Among others, the following factors were related with the risk of adverse events among HCWs due to PPE use: female gender, younger age, obesity, diabetes mellitus, smoking pre-existing headache, longer duration of shifts wearing PPE, increased consecutive days with PPE, and increased exposure to confirmed or suspected COVID-19 patients.
Conclusion
The frequency of adverse events amongst HCWs due to PPE use is very high. Further studies should be conducted since the limitations of this review do not allow us to infer conclusive results especially in case of risk factors for the occurrence of adverse events. Healthcare facilities should take the necessary precautions and change the working conditions during the COVID-19 pandemic to prevent adverse events associated with PPE use and minimize harm to HCWs.
