We evaluated the age-specific mortality of unselected adult outpatients infected with SARS-CoV-2 treated early in a dedicated COVID-19 day hospital and we assessed whether the use of hydroxychloroquine (HCQ) + azithromycin (AZ) was associated with improved survival in this cohort. A retrospective monocentric cohort study was conducted in the day hospital of our center from March to December 2020 in adults with PCR-proven infection who were treated as outpatients with a standardized protocol. The primary endpoint was 6-week mortality, and secondary endpoints were transfer to the intensive care unit and hospitalization rate. Among 10,429 patients (median age, 45 [IQR 32-57] years; 5597 [53.7%] women), 16 died (0.15%). The infection fatality rate was 0.06% among the 8315 patients treated with HCQ+AZ. No deaths occurred among the 8414 patients younger than 60 years. Older age and male sex were associated with a higher risk of death, ICU transfer, and hospitalization. Treatment with HCQ+AZ (0.17 [0.06-0.48]) was associated with a lower risk of death, independently of age, sex and epidemic period. Metaanalysis evidenced consistency with 4 previous outpatient studies (32,124 patients-Odds ratio 0.31 [0.20-0.47], I 2 = 0%). Early ambulatory treatment of COVID-19 with HCQ+AZ as a standard of care is associated with very low mortality, and HCQ+AZ improve COVID-19 survival compared to other regimens.
Abbreviations HCQ, hydroxychloroquine; AZ, azithromycin; IFR, infection fatality rate. Author contributions MMillion designed and supervised the study, conducted the investigation, formal analysis and wrote the first draft of the manuscript, JCL participated in the study design, investigation and critical review, all authors (HTD, IR, CD, CT, NC, SA, CA, KB, BD, SE, MH, MMailhe, CP, PS, CT, SG, EJ, AGG, HC, LCJ, PC, PG, PEF, BM, JCD, PH, JYG, AJ, SH, KGL, YO, PP, PB) participated in the investigation and provided constructive criticism and comments, LD, CB and SC conducted the formal analysis and meta-analysis, DR designed and supervised the study, and final proofreading with key finalization of the text. Ethics approval and consent to participate Data presented herein were collected retrospectively from the routine care setting using the electronic health recording system of the hospital. The retrospective nature of the study was approved by our institutional review board committee (Méditerranée Infection N • : 2021-007). As previously reported [15] , for all patients, the prescription of HCQ+AZ was made during day hospital attendance by one of the physicians, after a collegial decision based on the most recent scientific data available and after assessment of the benefit/harm ratio of the treatment. According to European General Data Protection Regulation No 2016/679, patients were informed of the potential use of their medical data and that they could refuse the use..
