Von Korff et al developed a Chronic Disease Score (CDS) that evaluates a patient's chronic disease status based on the need for drug therapy. This can be derived using information stored in pharmacy computer databases. The authors are from the Group Health Cooperative of Puget Sound in Seattle, Washington.

chronic disease score =
= SUM(points for chronic disease medications)
Interpretation:
• minimum score: 0
• maximum score: 36
• The higher the score, the more likely that the patient will be hospitalized and/or die.
Limitations:
• Some of the agents described are no longer commonly prescribed, while newer agents for treating the conditions are not listed.
• Some chronic infections like AIDS or viral hepatitis C are not represented.
Purpose: To evaluate a patient's health based on long term drug therapy using the chronic disease score of Von Korff et al.
Objective: severity, prognosis, stage
ICD-10: ,
