 Synthetic Healthcare Database for Research (SyH-DR)

Published by Agency for Healthcare Research and Quality | U.S. Department of Health & Human Services | Metadata Last Checked: August 08, 2025 | Last Modified: 2023-09-15
The Agency for Healthcare Research and Quality (AHRQ) created SyH-DR from eligibility and claims files for Medicare, Medicaid, and commercial insurance plans in calendar year 2016. SyH-DR contains data from a nationally representative sample of insured individuals for the 2016 calendar year. SyH-DR uses synthetic data elements at the claim level to resemble the marginal distribution of the original data elements. SyH-DR person-level data elements are not synthetic, but identifying information is aggregated or masked.
