Background and Objective: Few small observational studies have described various therapeutic interventions utilized in coronavirus disease 2019 (COVID-19) patients based on single/multi-center experiences across the globe. Understanding the utilization of available and possible treatments to curb the COVID-19 pandemic is paramount. We aimed to identify the prevalence and disease-associated utilization of specific therapeutic reagents in hospitalized COVID-19 patients as a function of severity status.

Methods: In systematic review and meta-analysis, extracted data on treatments utilized and severity of COVID-19 hospitalized patients from observational studies using PRISMA guidelines from December 1, 2019 to August 20, 2020. The pooled prevalence and odds of treatment utilization were obtained, and created forest plots using random‐effects models. 

Results: 29 studies with 8570 COVID-19-positive patients were included. Higher odds of the utilization of steroids (pooled OR:4.47; 95%CI:3.18–6.28; p<0.00001), antibiotics (3.1;1.81–5.30; p<0.0001), and IV Immunoglobulin (IVIG) (3.76;2.11–6.72; p<0.00001) was observed in patients with severe disease. No association of remdesivir (initially administered via clinical trials and subsequently FDA-approved during this study period), lopinavir/ritonavir, or hydroxychloroquine (HCQ) treatment with the severity of disease was observed.

Conclusion: Higher utilization of steroids, lopinavir/ritonavir, antibiotics, hydroxychloroquine (HCQ), and IV Immunoglobulin (IVIG) was observed in severe COVID-19 patients. Due to limited studies on remdesivir, its accurate utilization could not be delineated. Currently, no Level A evidence favoring single-drug treatment for COVID-19 exists, and trials are needed of combination therapy to evaluate efficacy on the survival outcome.
