The Health Data Access Initiative (HDAI)

Health care utilization data from the federal Centers for Medicare and Medicaid Services (CMS) are a key data source for population health research. UC researchers collectively spend millions of dollars each year accessing these data, yet once purchased, they can be re-used for a fraction of the cost.

CPL seeks to make these data accessible to a wider range of UC students and researchers.

The Health Data Access Initiative (HDAI) will establish a UC-wide repository for Medicare and Medicaid data from CMS. CPL will use a pool of funding to purchase CMS data costing hundreds of thousands of dollars. The HDAI will then make it possible for UC researchers to re-use these CMS data for an accessible $2,000 fee, plus some administrative fees.

HDAI will support a range of projects across the social and health sciences.

What data are available?

HDAI’s current projects and datasets are listed in the table below. These datasets are national in scope, and not just for California. The full listing of data available from CMS is here.  Through our seed grant program, CPL will consider matching funding for researchers purchasing CMS data through HDAI. This can substantially lower the costs for research times, both through the matching funding and by reusing existing data from prior HDAI projects.

 

 

What is the process for requesting access to the data?

If you’re interested in using the CMS data, reach out to CMS-reuse@capolicylab.org with a paragraph describing your research project, and any information about the data that would be required.
