5/20/2015:  The UMMS student chapter of the Gold Humanism Honor Society (GHHS) elected Dr. Courtney Collins as one of six UMass residents to be inducted into the Gold Humanism Honor Society this year. Residents are chosen for their commitment to teaching and their kind and compassionate treatment of patients, families, students, and colleagues. Being elected to GHHS from the large pool of housestaff at UMass is a major achievement and an acknowledgement of Dr. Collins serving as an exemplar of humanism to the students.

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.  



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, 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.
