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 or 1, Group 2 is a score of 2, Group 3 is a score of 3 or higher.



Cerebrovascular Disease
Chronic Pulmonary Disease
Congestive Heart Failure
Connective Tissue/Rheumatic Disease
Diabetes Without End Organ Damage
Diabetes With End Organ Damage
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, the annual hospital volume of pancreatic resections 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.
