RESUMO

OBJECTIVES: This study aimed to evaluate the effect of administering nirmatrelvir/ritonavir and molnupiravir before hospitalisation on subsequent critical illness among patients with COVID-19 pneumonia. METHODS: This retrospective cohort study included patients with COVID-19 pneumonia who required hospitalisation between 1 January 1 2022 and 31 August 2022. The primary outcomes were the development of critical illness, including intensive care unit admission, use of mechanical ventilation, or mortality. A multivariate logistic regression analysis was conducted to assess the varying risks of critical illness and mortality. A total of 1,011 COVID-19 patients were analysed. Among them, 304 (30.1%) received molnupiravir and 131 (13.0%) received nirmatrelvir/ritonavir before hospitalisation. RESULTS: There were significant reductions for critical illness (adjusted odds ratio 0.29, 95% confidence interval 0.21-0.39, P < 0.001) and mortality (adjusted odds ratio 0.40, 95% confidence interval 0.27-0.59, P < 0.001) in patients receiving oral antivirals compared with those who did not. No significant differences in critical illness were observed between molnupiravir and nirmatrelvir/ritonavir. The combination of COVID-19 vaccines and oral antivirals can further reduce the risk of critical illness in high-risk populations. CONCLUSION: Administering molnupiravir and nirmatrelvir/ritonavir before hospitalisation reduced the risk of COVID-19 patients with moderate to severe pneumonia progressing to critical illness and mortality.
