Abstract Objectives The main aim of this study was to find the prevalence of mortality among hospitalized COVID-19 infected patients and associated risk factors for death. Methods Three electronic databases including PubMed, Science Direct and Google Scholar were searched to identify relevant cohort studies of COVID-19 disease from January 1, 2020, to August 11, 2020. A random-effects model was used to calculate pooled prevalence rate (PR), risk ratio (RR) and 95% confidence interval (CI) for both effect measures. Cochrane chi-square test statistic Q, I 2 , and 𝜏 2 tests were used to measure the presence of heterogeneity. Publication bias and sensitivity of the included studies were also tested. Results In this meta-analysis, a total of 58 studies with 122,191 patients were analyzed. The pooled prevalence rate of mortality among the hospitalized COVID-19 patients was 18.88%, 95% CI (16.46–21.30), p
