Changes in Oxygenation and Clinical Outcomes with Awake Prone Positioning in Patients with Suspected COVID-19 In Low-Resource Settings: A Retrospective Cohort Study

Zusammenfassung:Introduction This study aimed to describe the use of awake prone positioning (APP) and conventional oxygen therapy (COT) in patients with suspected coronavirus disease (COVID-19) and respiratory failure in a limited-resource setting. Methods This was a retrospective cohort study of hospitalized patients aged ≥18 years old who were placed in an awake prone position due to hypoxemic respiratory failure and suspected COVID-19. The patients were selected from a tertiary center in Cartagena, Colombia, between March 1, 2020, and August 31, 2020. Demographic, clinical, and laboratory variables were collated, and all the variables were compared between the groups. Results The median age of the participants was 63 (IQR, 48.8-73) years (survivors: 59 [IQR, 43.568] years vs. non-survivors: 70 [IQR, 63-78] years, P ≤ .001). Of the 1470 patients admitted for respiratory symptoms, 732 (49.8%) were hospitalized for more than 24 h, and 212 patients developed respiratory failure and required COT and APP (overall hospital mortality, 34% [73/212]). The mean rank difference in PaO2/FiO2 before and after APP was higher in the survivors than in the non-survivors (201.1-252.6, mean rank difference = 51.5, P = .001 vs. 134.1-172.4, mean rank difference = 38.28, P = .24, respectively). Conclusion While using COT in conjunction with APP can improve respiratory failure in patients with suspected COVID-19 in low-resource settings, persistent hypoxemia after APP can identify patients with higher mortality risk. More evidence is needed to establish the role of this strategy.
