Uniform Data System
The Uniform Data System (UDS) is a core system of information appropriate for reviewing the operation and performance of health centers. UDS is a reporting requirement for Health Resources and Service Administration (HRSA) grantees, including community health centers, migrant health centers, health care for the homeless grantees, and public housing primary care grantees. The data are used to improve health center performance and operation and to identify trends over time. UDS data are compared with national data to review differences between the U.S population at large and those individuals and families who rely on the health care safety net for primary care.
