Comorbidity Score of Davies et al for a Patient with Chronic Renal Failure

Patient selection: chronic renal failure undergoing continuous ambulatory peritoneal dialysis

Comorbid conditions:

(1) malignancy

(2) ischemic heart disease (angina, ECG change, history of AMI)

(3) peripheral vascular disease (including aortic, limb or cerebrovascular)

(4) left ventricular dysfunction with pulmonary edema not attributable to fluid overload

(5) diabetes mellitus

(6) systemic collagen vascular disease

(7) other (COPD, pulmonary fibrosis, tuberculosis, cirrhosis, asthma)

comorbidity score =

= SUM(points for all comorbid conditions)

Interpretation:

• minimum score: 0 (or 1 if chronic renal failure included)

• maximum: 7 or more (if "other" is counted once or for each one present)

• The greater the number of cormorbid conditions the greater the comorbidity.
