Goals and benefits

What is the Uniform Data System (UDS)?

The Uniform Data System (UDS) is a standardized reporting system made up of a core set of data and measures that Health Center Program awardees and look-alikes are required to report on each calendar year. We use UDS data to assess the impact and performance of the Health Center Program and to promote data-driven quality improvement.

What is the UDS Modernization Initiative?

UDS modernization is a continuous effort to improve UDS content, quality, and reporting procedures. These efforts focus on reducing reporting burden and improving data quality and granularity to better evaluate Health Center Program services and outcomes. The goal is to optimize the use and value of UDS data for health centers and us while improving how health centers prepare and submit UDS data.

What is UDS+?

UDS+ is the electronic submission of de-identified patient-level data from health centers to us that corresponds with portions of existing UDS data elements, including information related to: 

• Health center patient demographics
• Health center services utilized
• Select electronic Clinical Quality Measures (eCQMs)

Data is transmitted to us using Fast Healthcare Interoperability Standards (FHIR®). These reporting standards are actively being adopted across the Department of Health and Human Services and the health care industry. 

(Updated: 4/22/2024)

How does UDS+ reporting differ from UDS reporting?

UDS data is reported in aggregate, tabular formats within EHBs. Many health centers are supported by their HIT vendors in gathering the UDS data, but the data submission is done manually at the health center. 

UDS+ data reporting includes de-identified patient-level data. It will be automated and may require more support and coordination with a health center’s HIT vendor(s). Some health centers will be able to self-report their UDS+ data to us, but the majority will work with their vendors. We have been working with HIT vendors to develop their ability to support UDS+ data submission via FHIR®. 

(Updated: 4/22/2024)

What is the timeline for adopting UDS+?

For CY24 UDS reporting (submission in 2025), we require a minimum submission of de-identified patient-level data (UDS+). The UDS+ submission is due April 30, 2025. To learn more, view our 2024 UDS+ Requirements One-Pager (PDF - 221 KB), and join the UTC.

Health centers will continue to submit aggregated legacy UDS data through the HRSA Electronic Handbooks (EHBs) as the official submission of record. The legacy UDS submission is due February 15, 2025. Sign up for the Primary Health Care Digest to receive the latest updates.

(Updated: 8/23/2024)

How will UDS+ data be used?

Data submitted through UDS+ will serve the same primary purpose of legacy UDS data: to assess the impact and performance of the Health Center Program and to promote data-driven quality improvement. 

UDS+ will provide us with valuable insight into patients’ experiences with receiving their care at HRSA-supported health centers. De-identified patient-level data allows us to cross-reference important factors that influence care-seeking behavior, care received, and patient health outcomes. This information is critical in advancing quality improvement and health outcomes for the Health Center Program, including tailoring training and technical assistance (T/TA) and funding opportunities. 

(Updated: 4/22/2024)

How will UDS+ benefit health centers?

UDS+ will provide multiple benefits to health centers by:

• Reducing reporting burden so health centers can better focus on delivering care to patients; health centers will be able to electronically report data from their EHR system and reduce reliance on manual data entry
• Improving data quality and the ability of health centers and us to communicate the complexity of the patient populations served
• Preparing health centers for reporting their data in accordance with federal interoperability standards

Organizations at the local, state, and federal level will also use UDS+ data to provide targeted T/TA and advance quality improvement research to improve access to high-quality, cost-effective care. Read more about patient privacy under Why patient-level data is important.

Why patient-level data is important

Why do you need patient-level data?

De-identified patient-level data allows us to cross-reference important factors that influence care-seeking behavior, care received, and patient health outcomes. This information is becoming increasingly critical for advancing quality improvement and health outcomes for the Health Center Program, including tailoring technical assistance and funding opportunities. 

Collecting patient-level data is not an end to itself; it is the means to allow us to better detect areas of opportunity within the program, track emerging and ongoing health trends, direct resources to where they matter most, and better engage in urgent or developing threats to poor health outcomes.

Examples of how we can use de-identified patient data to improve health outcomes and address health equity include:

• Identify the specific needs, health outcomes, and interventions of value to special populations, and work collaboratively within HRSA and HHS to identify available supports and programs. For example, veterans experiencing homelessness often have unique health needs and may be eligible to receive support from programs designed to support this population. We could better target resources to help those populations by understanding which health centers serve a significant portion of that population. However, currently, the UDS cannot show the number of patients who are both veterans AND experiencing homelessness within a health center’s patient population. 
• Collect “routine patient” indicators. Health outcomes of routine patients who visit a health center regularly may be different from patients who only visit a health center once. Patient-level data allows HRSA and health centers to analyze the two patient populations separately and address different trends and outcomes that may exist. 
• Identify patient populations that may be at higher risk in the event of another public health emergency or may be eligible to receive interventions based on their specific demographics. In the event of another PHE where limited resources must be disbursed to higher-risk populations, we will have the information required to administer our program effectively and equitably.

When UDS+ is implemented, will patient privacy be protected?

Yes, patient privacy will be protected. We require health centers and vendors to comply with the HHS Safe Harbor Method for patient data de-identification to ensure alignment with HIPPA rules.

Data submitted to UDS+ is not copied directly from a patient’s electronic health record (EHR). The data collected from the EHR passes through a solution at the health center or vendor system-level that de-identifies the data. The de-identification specifications are included in the UDS+ FHIR IG®. This means that the data is fully de-identified prior to being submitted to us and cannot be re-identified by any entity other than the health center. This is done to ensure that no identifiable information is submitted to our IT environments. In addition, our IT environments have data checks in place to ensure that protected health information (PHI) cannot enter our systems. 

We recognize that while the UDS+ data is de-identified, these data are still sensitive and we are taking every step we can to protect patient privacy.

(Updated: 4/22/2024)

How can reporting patient-level data reduce health centers’ reporting burden?

Traditionally, UDS data is generated through health centers’ EHR systems by looking through patient records. The information is then manually aggregated at the health center level. By reporting de-identified patient-level data, health centers will be able to leverage technology to bypass the manual aggregation step.

Adoption of FHIR® standards: 

• Aligns with the Centers for Medicare & Medicaid Services electronic clinical quality measures (eCQMs)
• Allows for the standardization of data
• Reduces the potential for misinterpretation of measures or calculation errors

What is HL7® FHIR® R4?

FHIR® stands for Fast Healthcare Interoperability Resources. Plans are underway to enable UDS+ reporting via FHIR®, an application programming interface (API)-focused standard that enables the quick and efficient exchange of health data. Interoperability of electronic health information continues to improve with wider adoption of FHIR® standards and associated clinical quality reporting architecture. Learn more by accessing the FHIR® Fact Sheets.

How to prepare for UDS+

How can health centers prepare for UDS+?

• Join the UDS Test Cooperative (UTC).
• Review publicly available HL7® FHIR® resources, including HL7.org and the HL7® FHIR® resources page.
• Collaborate with your HIT vendors directly and encourage them to consider participating in the UDS+ proof of concept and testing activities through joining the UTC.
• Visit the UDS Modernization Initiative webpage to learn more.
• Submit questions through the BPHC Contact Form.

(Updated: 8/23/2024) 

What is the UDS Test Collaborative (UTC)?

The UTC is a voluntary group of representatives from health centers, Primary Care Associations (PCAs), Health Center Control Networks (HCCNs), National Training and Technical Assistance Partners (NTTAPs), and HIT vendors. The group provides feedback on UDS Modernization. A steering committee of health centers representing diverse HHS Regions leads the group.

Please communicate your interest in joining the UTC via the BPHC Contact Form. 

If you are already a member of the UTC, visit the UDS+ Community in our Health Center Program Community (HCPC) to view past meeting presentations, recordings, and more. The HCPC is an online platform for participants in our specific programs to get timely updates, interact with other health centers, and access T/TA resources. If you do not have a login, select “Request Access,” and walk through the steps to request one.

(Updated: 4/22/2024) 

When does the UTC meet?

The UTC currently meets on the third Wednesday of the month, 2 – 3 p.m. ET. We ask that you first join the UTC and then you may register to attend the meetings.

In addition, we are hosting monthly UDS+ Office Hours on Thursdays, 1 – 2 p.m. ET. The purpose of these office hours is to provide participants an open forum to ask questions and follow up with the UDS+ team about registration and testing issues. The office hours are open to both technical and non-technical participants.

(Updated: 8/23/2024)  

What is the UTC currently testing?

Currently, the UTC is providing input and feedback on the CY24 UDS+ onboarding, testing and submission process. 

The UTC Steering Committee and UTC members are critical partners to us at this stage of UDS+ implementation. The UTC meetings include the most current updates on the program and allow our staff to learn what opportunities and barriers health centers are encountering in preparing for UDS+ data submission. 

We continue seeking volunteers to engage in UDS+ proof of concept and testing activities, including testing two data receiving endpoints that support FHIR®, using the current version of the FHIR® Implementation Guide (IG). The UDS+ FHIR® IG provides the architectural details and technical reporting specifications for UDS+. Health centers will test the servers’ functionality and ability to receive comprehensible UDS+ data files. Additionally, these tests will be used to ensure the accuracy and validity of UDS+ data elements.

(Updated: 2/27/2023)

What technology do health centers need in place to be a test site?

Health centers, PCAs, HCCNs, and HIT vendors participating in the submission of UDS+ must have the right infrastructure, including a:

• Bulk FHIR®-enabled EHR system
• Backend Service App
• Trust Services mechanism to support de-identification of patient data before sending to us

Additionally, health centers, PCAs, HCCNs, and HIT vendors will need to participate in a registration process to ensure their systems have the appropriate security requirements. 

For more information about the registration process, submit inquiries via the BPHC Contact Form.

CY24 UDS+ minimum required submission

What is the CY24 UDS+ reporting requirement?

All health centers are required to submit a full legacy UDS Report within EHBs by February 15, 2025. This is the submission of record.

Beginning with the 2024 UDS reporting cycle, health centers are also required to submit a minimum amount of de-identified patient-level data (UDS+) using HL7® FHIR® standards. Technical specifications for UDS+ are available in the UDS+ FHIR® Implementation Guide (IG) on the HL7® website.

Requirement 1: Medical patients only

Health centers are required to submit UDS+ data for medical patients only. Data for patients receiving dental, behavioral, or other services not included in the electronic medical record is not required. Health centers that are able to send full patient population are encouraged to do so.

Requirement 2: All demographic tables

Health centers are required to submit data corresponding to measures on the following tables:

• Patients by ZIP Code
• Table 3A: Patients by Age and by Sex Assigned at Birth
• Table 3B: Demographic Characteristics
• Table 4: Selected Patient Characteristics

Requirement 3: One electronic clinical quality measure (eCQM)

Health centers are required to submit one eCQM from one of the clinical tables:

• Table 6B: Quality of Care Measures
  • Breast Cancer Screening
  • Cervical Cancer Screening
  • Colorectal Cancer Screening
• Table 7: Health Outcomes and Disparities
  • Controlling High Blood Pressure (HRSA Recommended)
  • Diabetes HbA1c Poor Control

(Added: 8/23/2024)

When is the CY24 UDS+ minimum required submission due to you?

The full legacy UDS Report with EHBs is due February 15, 2025.

All health centers are required to submit the CY24 UDS+ required minimum data by April 30, 2025.

(Added: 8/23/2024)

What if my UDS+ FHIR® data is inconsistent with my UDS data submission via EHBs?

Health centers will not be penalized for variations between data submitted using FHIR® and EHBs. The CY24 UDS+ submission will only include medical patients for many health centers, so we expect variance.

(Added: 8/23/2024)

What if my HIT vendor is not ready to support UDS+ submission yet?

We understand that there will be implementation questions unique to a health center. Please submit your questions about UDS+ submission through the BPHC Contact Form.

(Added: 8/23/2024)

What if my health center is in the middle of switching HIT vendors?

We understand that there will be implementation questions unique to a health center. Please submit your questions about UDS+ submission through the BPHC Contact Form.

(Added: 8/23/2024)

Will health centers be able to review their UDS patient-level data?

Yes, we are developing a mechanism to allow health centers to review their UDS+ submission. UDS+ review and submission functionality is in development and we will provide details on these at a later time.

(Updated: 6/5/2023)

Will health centers be able to validate submitted UDS+ data to ensure accuracy?

Layers of validation are built into the FHIR® transactions, but we are also developing internal business logic to perform validation analyses on the submitted patient-level data. UDS+ review functionality is in development and we will provide details on these at a later time. 

(Updated: 6/5/2023)

How will the de-identification process work?

Data will be de-identified at the health center level using Trust Services before submission to us. De-identification details are outlined in the UDS+ FHIR® IG. Health centers are encouraged to work with their vendors directly to develop a strategy and plan for submission to us. 

(Updated: 1/3/2024)

Will the Preliminary Reporting Environment (PRE) be available for both UDS+ and traditionally aggregated format tables?

The PRE will be available for traditionally aggregated format UDS tables. UDS+ review and submission functionality is in development and we will provide details on these at a later time. 

(Updated: 6/5/2023)

Where to go for more information

Is there funding to support UDS+ implementation?

Yes. In June 2024, we released $56 million in one-time fiscal year 2024 funding to all HRSA-funded health centers. This Quality Improvement Award funding is intended to support HRSA-funded health centers to prepare for and implement programs and technologies to ensure high-quality, patient-level data submissions as part of UDS+. Read more on the FY 2024 QIA-UDS+ Award.

On August 8, 2022, we awarded FY 2022 ARP-UDS+ supplemental funding. These funds were made available to support high-quality UDS+ submissions. 

We also added a one-time $40,817 funding supplement to Fiscal Year 2022 Health Center Controlled Network awards. This funding was used to support T/TA on UDS+. Find more information on Submit your HCCN Progress Report.

(Updated: 5/16/2024)

Where should I go for training and technical assistance on FHIR (Bulk FHIR® API, SMART on FHIR®, USCDI/US Core, FHIR® Server, and FHIR® Client, etc.)?

Health centers, PCAs, and NTTAPs should contact their HCCNs or HIT vendors as T/TA resources. We also recommend that health centers reference and review HL7® FHIR® resources on HL7.org.
