HRSA UDS: Definition and Healthcare Context

Full name: HRSA Uniform Data System

The HRSA Uniform Data System (UDS) is an annual reporting system through which federally funded health centers — Federally Qualified Health Centers (FQHCs), FQHC Look-Alikes, and other Health Center Program grantees — submit standardized performance and patient demographic data to the Health Resources and Services Administration. UDS data covers patient characteristics, clinical quality measures, staffing, financial information, and services delivered at each grantee site. HRSA uses UDS data to monitor grantee performance against program requirements and publishes aggregate and site-level data publicly through the UDS Mapper and flat-file downloads. The UDS dataset covers approximately 1,400 grantees operating over 15,000 service delivery sites serving approximately 31 million patients annually.

How it’s used

  • HRSA Uniform Data System (UDS): Fonteum ingests annual UDS data covering approximately 9,000 FQHC sites to power health-access research, provider shortage analysis, and FQHC coverage gap studies.
  • HRSA Health Professional Shortage Areas (HPSA): UDS site locations are overlaid against HPSA geographic boundaries to identify health center presence in shortage areas and measure access-gap coverage.
  • CMS NPPES NPI Registry: FQHC sites in UDS are cross-referenced with NPPES provider records via NPI to link site-level utilization data with individual practitioner identities.

Frequently asked questions

What is the HRSA Uniform Data System?
The HRSA UDS is the annual reporting system for HRSA-funded health centers (FQHCs and Look-Alikes). Grantees submit patient demographic, clinical quality, staffing, and financial data each year.
Who must report to the UDS?
All HRSA Health Center Program grantees — including Federally Qualified Health Centers and FQHC Look-Alikes — are required to submit annual UDS reports as a condition of their funding.
Is UDS data publicly available?
Yes. HRSA publishes UDS data through the UDS Mapper interactive tool and flat-file downloads at data.hrsa.gov, covering grantee locations, patient volume, and clinical quality measures.
