Physician and Physician Practice Research Database (3P-RD)

The Physician and Physician Practice Research Database (3P-RD) captures characteristics of physicians and physician practices in 13 states. The database describes the supply of physician services available across selected states for data year 2019-2020. AHRQ created 3P-RD as a resource to address existing data gaps in physician health services information at the state and market levels.

3P-RD consists of both public use and restricted use data files. The public use file (PUF) version of 3P-RD is currently available for download. Go to data files and documentation below.

The Restricted Use File (RUF) version of 3P-RD will be available for each state. Once the data are released, a data use agreement (DUA) will be required for access to the data files.

  • The Agency for Healthcare Research and Quality (AHRQ) created the 3P-RD core files by linking state medical board licensure data to the National Plan & Provider Enumeration System (NPPES) and the Medicare Provider Enrollment, Chain, and Ownership System (PECOS) for data year 2019-2020. The database was supplemented and enhanced using available state and national claims files.
  • 3P-RD contains harmonized data elements related to physician and physician practice data characteristics for 13 states: Arkansas, Arizona, California, Colorado, Florida, Massachusetts, Maryland, Minnesota, Missouri, Montana, New York, Texas, and Washington.
  • 3P-RD was designed as a resource to address supply-side policy questions and to support policy-relevant health services research.
  • 3P-RD contains linkable files for physicians and physician practices in each of 13 states, focused on the current roles of actively practicing physicians and corresponding relationships within practices and facilities.
