IntroductionThe development of acute respiratory distress syndrome indicates a serious form of COVID-19. Although there have been several studies on the prognostic factors of its severe form, no such study has been conducted in Burkina Faso.MethodsThis was a retrospective cohort study conducted from March 9 to June 9, 2020 in Ouagadougou, Burkina Faso which involved 456 patients with COVID-19.ResultsNearly a quarter of the patients (23.2%) had presented with acute respiratory distress and 44.3% of them died. Being over 65 years old (HR: 2.7; 95% CI: 1.5-5.1) and having hypertension (HR: 1.9; 95% CI: 1-3.5) were independently associated with the risk of mortality. However, after adjustment, only age over 65 years (HR: 2.3; 95% CI: 1.2-4.3) was a risk factor for death. The survival rate for patients over 65 was 38.5% at 7 days and 30.3% at 15 days.ConclusionsAcute respiratory distress leading to death is mainly found in older people with COVID-19. Close monitoring of these high-risk patients may reduce the risk of death.Copyright © 2021 SPLF. Published by Elsevier Masson SAS. All rights reserved.
