About this calculator
Overview
The Charlson Comorbidity Index (CCI) is a validated method of classifying comorbid conditions that might alter the risk of mortality for patients. It is widely used to assess prognosis in clinical research and to adjust for confounding in epidemiological studies.

Pro Tips
Use recent clinical documentation to capture all relevant diagnoses.
Metastatic solid tumor (6 points) is the single most heavily weighted comorbidity.
A score of 0 implies no significant comorbidities and suggests excellent long-term survival.

Fun Facts
"First published in 1987 by Mary Charlson and colleagues."
"The index predicts the ten-year mortality for a patient who may have a range of comorbid conditions."
"Age is a significant independent factor added to the base comorbidity score."
"Higher CCI scores are associated with increased risk of post-operative complications."
Formula: CCI = Sum(Comorbidity Points) + Age Adjustment (+1 for each decade > 40).
