Global prevalence and determinants of mortality among patients with COVID-19: A systematic review and meta-analysis

Background: The challenge of COVID-19 is very high globally due to a lack of proven treatment and the complexity of its transmission. The prevalence of in-hospital mortality among patients with COVID-19 was very high which ranged from 1 to 52% of hospital admission. The prevalence of mortality among intensive care patients with COVID-19 was very high which ranged from 6% to 86% of admitted patients. Methods: A three-stage search strategy was conducted on PubMed/Medline; Science direct Cochrane Library. The Heterogeneity among the included studies was checked with forest plot, χ2 test, I2 test, and the p-values. Publication bias was checked with a funnel plot and the objective diagnostic test was conducted with Egger's correlation, Begg's regression tests. Result: The Meta-Analysis revealed that the pooled prevalence of in-hospital mortality in patients with coronavirus disease was 15% (95% CI: 13 to 17). Prevalence of in-hospital mortality in patients with COVID-19 was strongly related to different factors. Patients with Acute respiratory distress syndrome were eight times more likely to die as compared to those who didn't have, RR = 7.99(95% CI: 4.9 to 13). Conclusion: The review revealed that more than fifteen percent of patients admitted to the hospital with coronavirus died. This presages the health care stakeholders to manage morbidity and mortality among patients with coronavirus through the mobilization of adequate resources and skilled health care providers. Registration: This systematic review and meta-analysis was registered in research registry with UIN of reviewregistry1093. HIGHLIGHTS The review revealed that more than fifteen percent of patients admitted to the hospital with coronavirus died. The rate mortality among COVID-19 patients in the Intensive Care Unit was Twenty-nine percent. The Meta-Analysis revealed that sepsis was the most prevalent complication. Rate of mortality among COVID-19 was eight times more likely in patients with ARDS.
