Conclusion: In our hospital, the main therapeutic changes between W1 and W2 were use of steroids for hypoxemic patients and HFNO, while fewer patients received MV fort shorter durations and 4.7% of W2 patients were transferred to other hospitals in case of overcrowding. These changes were associated with a decrease in 30-day mortality, ICU admission and organ support, suggesting a better selection of patients requiring ICU, alleviating local overcrowding and likely improving quality of care and long-term recovery for survivors.
