Step 1. Calculate Charlson comorbidity score
Indicate "yes" for the comorbidities that the patient has. This validated algorithm (Charlson, ME et al. J Chron Dis 1987; 40(5):373-83.) assigns a point value to the various diseases. The patient's raw score will then be reassigned into the collapsed Charlson score groups for use in the risk score calculation. Group 1 is a score of zero, Group 2 is a score of 1, Group 3 is a score of 2, and Group 4 is a score of 3 or higher.
