Insights
The Charlson Comorbidity Index (CCI) effectively stratifies COVID-19 patient risk. Higher CCI scores correlate with increased mortality and severe outcomes in hospitalized patients.
Area of Science:
- Medical research
- Epidemiology
- Public health
Background:
- COVID-19 disproportionately impacts patients with comorbidities.
- Accurate comorbidity assessment is crucial for risk stratification upon hospital admission.
- The Charlson Comorbidity Index (CCI) is a validated tool for predicting mortality risk from comorbid diseases.
Purpose of the Study:
- To systematically review and meta-analyze the association between CCI scores and COVID-19 patient outcomes.
- To evaluate the prognostic value of CCI in predicting mortality and composite poor outcomes in hospitalized COVID-19 patients.
Main Methods:
- Systematic review and meta-analysis.
- Inclusion of studies assessing CCI scores and a composite of poor outcomes in COVID-19 patients.
Main Results:
- A CCI score of 1-2 and ≥3 was associated with increased mortality and composite poor outcomes compared to a CCI of 0.
- Each point increase in CCI score elevated mortality risk by 16%.
- Higher mean CCI scores significantly correlated with mortality and disease severity.
Conclusions:
- The CCI is a valuable tool for risk stratification in hospitalized COVID-19 patients.
- Utilizing CCI can aid in identifying high-risk individuals for targeted interventions.
Background And Aims:
The ongoing COVID-19 pandemic is disproportionately affecting patients with comorbidities. Therefore, thorough comorbidities assessment can help establish risk stratification of patients with COVID-19, upon hospital admission. Charlson Comorbidity Index (CCI) is a validated, simple, and readily applicable method of estimating the risk of death from comorbid disease and has been widely used as a predictor of long-term prognosis and survival.
Methods:
We performed a systematic review and meta-analysis of CCI score and a composite of poor outcomes through several databases.
Results:
Compared to a CCI score of 0, a CCI score of 1-2 and CCI score of ≥3 was prognostically associated with mortality and associated with a composite of poor outcomes. Per point increase of CCI score also increased mortality risk by 16%. Moreover, a higher mean CCI score also significantly associated with mortality and disease severity.
Conclusion:
CCI score should be utilized for risk stratifications of hospitalized COVID-19 patients.
