Charlson Comorbidity Index Score and its impact on severe outcome and death in COVID-19 cases: A retrospective analysis

Abstract

Background and aims: The COVID-19 disease disproportionately affects patients with various comorbidities. Hence, thorough comorbidities evaluation can help establish risk stratification and triaging of patients with COVID-19, upon hospital admission. Charlson Comorbidity Index (CCI) is a validated, simple, and readily appropriate method of assessing the risk of severe outcomes and death from comorbid diseases and has been widely used as a predictor of long-term prognosis and survival. Methods: We performed a retrospective analysis of the data obtained from Electronic Medical record of all the patients admitted to our hospital with positive COVID-19 RT PCR report between October and November 2020 using XLSTAT software. Results: Compared to a CCI score of 0, a CCI score of 1-2,3-4 and a CCI score of ≥4 were found to be associated with mortality and composite of the severe outcome. Conclusion: CCI score can be useful and maybe employed for risk assessment of hospitalized COVID-19 patients.
