Chronic Conditions Warehouse

Section 723 of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 instructed the Secretary of the U.S. Department of Health and Human Services to make Medicare data more readily available to researchers studying chronic illness in the Medicare population, with the intent to help “identify areas for improving the quality of care provided to chronically ill Medicare beneficiaries, [and] reduce program spending.” The Chronic Conditions Warehouse implements this requirement of the Act and contains fee-for-services claims, enrollment/eligibility, and assessment data. Researchers can efficiently access data on 21 predefined chronic health conditions, such as diabetes, breast cancer, Alzheimer’s, and depression.
