Chronic Disease & Pharmacotherapy Research Program

Program Lead: Michael Paterson
Program Coordinator:

The Chronic Disease and Pharmacotherapy (CDP) research program has two main areas of emphasis.  In the chronic disease area, scientists track the epidemiology, management and outcomes of chronic illnesses. Such illnesses include diabetes, arthritis, asthma and chronic obstructive pulmonary disease. The CDP program tracks these illnesses over time and among population subgroups and geographic areas.
In the area of pharmacotherapy, cutting-edge epidemiologic methods are used to examine the real-world use, safety and effectiveness of prescription drugs and drug insurance policies.
