Corrao et al reported the Multisource Comorbidity Score (MCS) as a measure of comorbidity. This can aid in risk adjustment. The authors are from multiple institutions in Italy.
hemiplegia or hemiparesis
disorder of fluid, electrolytes or acid-base balance
other neurological diseases
chronic pulmonary diseases
acute myocardial infarction
coronary and peripheral vascular disease
• It is assumed that each is independent except for cancer. Therefore, a person who receiving chemotherapy for metatastatic cancer would receive 23 points and a patient with end-stage renal disease on dialysis would get 8 points.
• Malignant lymphoma is separate from cancer.
• The list of conditions is limited.
• The distinction between vascular disease and coronary and peripheral vascular disease is uncertain.
total aggregate score =
= SUM(points for all conditions present)
The total aggregate score was then mapped into a category designated the Multisource Comorbidity Score (MCS).
0 to 4
5 to 9
10 to 14
15 to 19
• The area under the ROC curve is 0.78.
