Uniform Data System
The Uniform Data System (UDS) is a standardized set of data reported by federally funded programs such as the Indian Health Service (IHS) Urban Indian Organizations (UIOs), and Health Resources and Services Administration (HRSA) section 330 grantees and Federal Qualified Heath Centers. Urban Indian Organizations funded by the IHS are required to produce annual reports. For each of these reports, the UDS also produces lists of all patients and related visits that are counted in the reports.
The UDS National Summary report provides a standard set of annual reports that provide consistent information about UIOs. The UDS set of annual reports include aggregate information from various UIOs regardless of the electronic health record system utilized. Site specific UDS reports are automatically generated for sites that leverage the IHS National Data Warehouse (NDW). Sites that do not export data to the NDW complete UDS tables in an Excel format on local computers and then submit to IHS. Their data is then aggregated with the automated reports obtained from the NDW.
These reports provide an overview of patients and visits at an Urban Indian Organization, including aggregated total number, age, gender, zip code of residence, insurance sources, race/ethnicity of patients, number of visits by provider type, by key diagnoses and services, characteristics of special populations, quality of care indicators, health outcome, and disparities.
The UDS National Summary report is an annual calendar year report. UIOs must report on the entire calendar year. This is true even for UIOs whose designation or funding begins, either in whole or in part, after January 1 or ends before December 31. Similarly, UIOs with a fiscal year or grant period other than January 1 to December 31 will still report on the calendar year, not on their fiscal or grant year.
The UDS National Summary report does not contain any personally identifiable information (PII) data that could potentially identify a specific individual.
