As part of the Medicare Modernization Act of 2003 (MMA), the Chronic Condition Data Warehouse (CCW), a research database, has been launched by the Centers for Medicare & Medicaid Services (CMS). Section 723 of the MMA outlined a plan to “improve the quality of care and reduce the cost of care for chronically ill Medicare beneficiaries.” An essential component of this plan was to establish a data warehouse that contained various types of Medicare data from multiple settings and providers, linked across data sources.

The Iowa Foundation for Medical Care (IFMC) contracted with CMS to design, implement, and support this extensive patient-level continuum of care database. For a 5% random sample of Medicare beneficiaries, data for care received in inpatient, outpatient, home health, skilled nursing, hospice, nursing home, and physician office settings, as well as durable medical equipment services, are available from 1999 forward. These sources are linked across the continuum of care by a unique, unidentifiable beneficiary key to construct a patient-centric view of enrollment and service utilization. Future plans for the CCW will include the addition of Medicare prescription drug and Medicaid data.

While data for all beneficiaries in the sample are available, researchers may request data for a specific, predefined cohort based on a set of twenty-one common chronic condition categories. The various data types available to researchers, as well as the data fields, selection, output and delivery options will be discussed during this presentation.

Learning Objectives: At the conclusion of the session, the participant will be able to

• Understand the background and purpose of the Medicare Chronic Condition Data Warehouse (CCW).
• Describe the contents and key features of the CCW.
• Assess individual researcher needs and appropriate uses of the CCW data.
