Importance Treatment options for Severe acute respiratory syndrome MESHD-related coronavirus-2 (SARS-CoV-2) are limited with no clarity on the efficacy and safety profiles. Objective To assess if the effect estimate of any intervention improves the outcomes and safety profile. Data sources PubMed, Embase, Cochrane Central were searched from December 1, 2019 to May 11, 2020. Study selection Any prospective/retrospective clinical study on SARS-CoV-2 patients above 18 years of age TRANS with report on therapeutic interventions. Data synthesis and extraction Data was screened and extracted by two independent investigators. Main outcomes and measures The primary outcome was all-cause in-hospital mortality. The secondary outcomes were rates of mechanical ventilation, viral clearance, adverse events, discharge, progression to severe disease MESHD, median time for clinical recovery and anti-viral clearance. Pooled rates and odds ratios (OR) were calculated. Results A total of 29 studies with 5207 participants were included in the analysis. The pooled all-cause in-hospital mortality rate was 12.8% (95%CI: 8.1%-17.4%) in intervention arm. There was no significant difference in mortality between both arms overall (OR: 1.36, 95% CI: 0.97-1.89). The mortality was significantly higher in the Hydroxychloroquine (HCQ) group compared to control: (1.86, 95% CI: 1.38-2.50). The need for mechanical ventilation in patients with mild-moderate disease MESHD was 13.5% vs 9.8% in intervention and control groups, with no significant difference (OR: 1.58, 95% CI: 0.60-4.15).The median duration for viral clearance in the intervention arm was 6.1 (IQR: 4.3-8.8) days and control arm was 9 (IQR: 4.5-14) days, with no significant difference between the groups (p = 0.37). There was no significant difference between pooled adverse event rates in intervention and control groups: 34% vs 29.5% (OR: 1.44, 95% CI: 0.70-2.94), respectively. However, incidence of adverse events was significantly higher in HCQ sub-group (OR: 3.88, 95% CI: 1.60-9.45, I2 = 0%). There was no significant difference in other secondary outcomes. Conclusion and relevance The use of hydroxychloroquine was associated with increased mortality and adverse event rates. No other therapeutic intervention including Lopinavir/Ritonavir, Remdesivir or Tocilizumab seem to alter the natural course of the disease MESHD. There is a further need for well-designed randomized clinical trials.
