How To Calculate Charlson Comorbidity Index.
However, there is no consensus regarding the weighting algorithm, with several competing definitions. This is useful if the comorbidity calculation is time consuming. The original index assigns a numerical value or “weight” from 1,2,3 or 6 to 19 specific chronic illnesses.
