The Standard

Thanks to the dedicated efforts of Gravity Project’s community members, volunteers, and staff, we made significant progress in advancing standards for Social Determinants of Health (SDOH) in 2024 that will shape the future of health data sharing.

Key Achievements

Gravity focuses on developing consensus-based standards that enhance data interoperability for SDOH. Our terminology, technical, and implementation workstreams all made notable progress in 2024 that we can leverage this year.  We provided valuable resources and guidance to help implementers adopt Gravity terminology effectively.

One of our standout initiatives was a six-week discovery project in February 2024, where over 20 cross-sector stakeholders collaborated to explore social care payment and reporting standards. This effort not only resulted in a comprehensive report but also fostered a deeper understanding of the landscape surrounding social care.

In its SDOH Playbook, “US Playbook to Address the Social Determinants of Health,” the White House explained that supporting flexible funding to address social needs, such as those offered through health-related social needs (HRSN) reimbursement programs, improves health outcomes: “Increasing funding flexibility and offering technical assistance that empowers organizations to utilize funding from a variety of sources will better equip them to address unmet social needs.”

The success of these reimbursement programs requires the existence of exchange and data standards that serve the interests of all stakeholders. Payers and community-based organization (CBOs) currently experience complexities and pain points that have presented challenges and made it difficult to meet the HRSN reimbursement programs’ full potential exist as these benefits roll out today.

As momentum has grown among states and payers for the reallocation of healthcare funds to address HRSNs, Gravity Project decided to undertake a discovery effort to understand and define the existing landscape for CBO reimbursement and identify the components of the CBO reimbursement process and where national standards play a role. 

"Unite Us is proud to work with the Gravity Project. Together, we are making it easier for community-based organizations to participate in Medicaid reimbursement programs, expanding the availability of these benefits to more individuals seeking care,” Emily Anders, director of payments strategy for Unite Us, said.

April 25 Session Focuses on the Observation Screening Response Profile

Join us on April 25, 2024, at 2:30 – 4 p.m. ET for the next Gravity Project Implementation Affinity Group meeting, which features more real-world implementations and a key to their success: the Observation Screening Response profile.

Bringing Observation Screening Response into Focus for Gravity Implementers

Building upon the implementation approach and presentation by New York State Qualified Entities in February, this month’s Gravity Implementation Affinity Group session focuses on more real-world implementations and a key to their success: the Observation Screening Response profile.

The benefits of using this profile include explicit categorization of question/answer pairs by social determinants of health (SDOH) domains, flagging of positive findings, and using a common language (Gravity standardized terminology) to share and communicate these findings.

This session will highlight Observation Screening Response, including guidance on using key elements (e.g., Observation.category and Observation.interpretation) and using Observation Screening Response to create Observation Groupings.

Opportunity in partnership with Kaiser Permanente, HL7 and others!

As grounding, the Gravity Project is a national consensus project that develops and tests data standards to represent and exchange social risk data in electronic systems. Together, with a broad collective of stakeholders, Gravity Project defines the language needed to comprehensively address social risks in clinical and community-based settings. To date, the terminology team has completed 17 social risk domains. This has included building critical screening, diagnosis, goal, and intervention concepts for food insecurity, housing instability and homelessness, transportation insecurity, and beyond. In addition, Gravity data standards are included in the United States Core for Data for Interoperability (USCDI), and their value sets serve as a reference for emerging social risk quality measures.

Highlighted here is a preview of what’s on the horizon as the Gravity Project matures and
recent examples of Gravity standards integration.

The Gravity Project®, an HL7® FHIR Accelerator, is evolving the way it advances social care data integration as a strategy to promote health equity while maintaining continuity with the mission and consensus-based processes that are core to the project. The project is a national public-private collaborative developing, testing, and implementing consensus-based social determinants of health (SDOH) data standards for use across the health, social services, public health, and research sectors. The Gravity community embodies a truly inclusive representation of over 2,500 stakeholder members of its public work groups and governance committees across the healthcare, health IT, community-based, federal and state agency, payer, academic, and patient/ consumer advocacy sectors.

In 2021, HL7 was awarded a cooperative agreement with the Office of the National Coordinator for Health Information Technology (ONC) to prioritize and expedite the development of standards specific to five gap areas including SDOH. Under this collaborative agreement, the Gravity Pilots Affinity Group was launched in September 2022 as a peer-to-peer learning forum for real-world testing of Gravity terminology and technical standards. Pilot sites are invited to demonstrate the use of social care coded terminologies (e.g., LOINC®, SNOMED-CT®, ICD-10®) and/or the HL7 SDOH Clinical Care FHIR Implementation Guide (SDOH CC IG), share implementation lessons learned with other pilot participants, seek/find partnerships for testing, and gain real-world experience.

Social Determinants of Health Data Matter for National COVID-19 Response Efforts

The Gravity Project is pleased to announce the publication of its consensus recommendations for food insecurity, housing instability and homelessness data elements. The Gravity Project is a national cross sector grassroots informed collective charged with building consensus data elements and data standards for the capture, exchange, and use of social determinants of health (SDOH) information. The Gravity food insecurity and housing data elements are the result of a year of development with input from its over 1,000 participants with intentional representation from key stakeholders such as patients, providers, community based organizations, payors, technology vendors, and federal and academic food insecurity and housing subject matter experts.

Social determinants of health—the circumstances in which we are born, grow, live, work and age—are estimated to account for 80-90% of health. There is growing interest from the healthcare sector to integrate social risk evaluation and intervention to advance the triple aim: improved health outcomes and quality of care while containing costs. In 2018, Gravity founders University of California San Francisco (UCSF) Social Interventions Research and Evaluation Network (SIREN) conducted an assessment of existing SDOH data and found much work was needed to advance the documentation and use of this data. Enter, the Gravity Project. The Office of the National Coordinator for Health Information Technology (ONC), a Gravity Project sponsor, noted the growing recognition across healthcare that by capturing and accessing SDOH data during the course of care, providers can more easily address non-clinical factors, such as food, housing and transportation insecurities, which can have a profound impact on a person’s overall health.
