| dc.description.abstract1 | Background Evidence suggests that semi-facial respirators provide protection against contamination in high-risk
environments, although the COVID-19 pandemic called for greater protection and viral inactivation capacity. Thus, the
aim of this study was to investigate the efficacy of a novel semi-facial respirator containing chitosan nanoparticles,
compared with a conventional N95 respirator on the incidence of laboratory-confirmed SARS-CoV-2 in healthcare
professionals. The secondary outcomes were influenza infection, usability and comfort.
Methods Randomized controlled trial within a large public hospital (reference for COVID-19 patients) carried out
between March 2021 and June 2023. We included 230 healthcare professionals exposed to SARS-Cov-2 and influenza,
working in emergency departments, hospital wards, and intensive care units. Participants were assessed at baseline,
after 10 days, and 21 days of follow-up. Researchers, participants, and outcome assessors were blinded to the
allocated groups. Outcomes were analyzed by bivariate and multivariate comparisons using logistic regression. Crude
(cOR) and adjusted odds ratios (aOR) were estimated, followed by 95% confidence intervals (CIs 95%). We adopted
intention-to-treat (ITT) and complete-case (CC) analyses.
Results Baseline characteristics were considered homogeneous between groups, and usability and comfort were
reported as excellent in both groups. Non-significant differences were found for all outcomes, both in the ITT and
CC analyses. The incidence of COVID-19 and influenza were, respectively, cOR: 0.96 [CI95%: 0.21–4.42] and cOR: 1.25
[CI95%: 0.34–4.62]; and aOR: 1.08 [CI95%: 0.21–5.47] and aOR: 1.11 [CI95%: 0.17–7.01]. Conclusions We found that the incidence of SARS-Cov-2 and influenza infections were similar between the new
respirator compared to the conventional respirator. Furthermore, we observed that usability and comfort were similar
and considered excellent for both respirators. | pt_BR |
