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.  

Comorbidity

AIDS   
Cerebrovascular Disease   
Chronic Pulmonary Disease   
Congestive Heart Failure   
Connective Tissue/Rheumatic Disease   
Dementia   
Diabetes Without End Organ Damage   
Diabetes With End Organ Damage   
Hemiplegia   
Liver Disease Mild to Moderate   
Liver Disease Severe   
Myocardial Infarction   
Peripheral Vascular Disease   
Renal Disease   
Ulcer Disease   
 
Charlson Group Score

 

Step 2. Calculate the risk score, including the Charlson group.
Patient age, Charlson score group, planned procedure type, gender, and the teaching status of the hospital are indicated.  The point values are assigned accordingly to yield an additive score.  By clicking on the "Calculate Estimated Mortality" button, this score is then assigned to the appropriate risk score group, and the mortality for that group is displayed.
