The Washington Gravity Project Workgroup

What is the Gravity Project? 

The Gravity Project is a national and international effort for “documenting and sharing SDH-related assessment, diagnosis, and treatment information using modern coding and exchange standards has the potential to improve whole person care and health outcomes.”i As a part of the HL7 FHIR Accelerator Program “creates and maintains a consensus-building community to expand available Core Social Determinant of Health (SDOH) Data for Interoperability and accelerate standards-based information exchange by using HL7 FHIR”ii 

The project covers three SDoH domains – Food Insecurity, Housing and Transportation. The standards being developed are tool agnostic and intended to be applicable to all Social Determinants domains in the future.  

This project is sponsored by SIREN, The Robert Wood Johnson Foundation and EMI Advisors and consists of a large group of stake holder, including Contra Costa Health Services, University of Victoria, NIH, Johns Hopkins, New York Department of Health, the FDA and many others participating regularly in community meetings to: 

a) submit data elements from different screening tools (validated or not),  

b) to review concepts and determine which ones are similar or the same  

c) and adjudicate which concepts are appropriate for the data set for the three identified domains.

What is the Gravity Project Schedule? 

Community Meetings: Meetings are held for 1 hour on Thursdays from 4:00pm-5:00pm ET / 1:00pm-2:00pm PT.   

The Association's Role in the Gravity Project

The Association is a member of the national community stakeholder’s group. Our role is to collect screening tools, surveys, information on interventions, community resources and other important data elements and concepts and push them up to the community group in a standardized format for adjudication.

We convene a Washington State Gravity Project Work Group who’s aim is to review submitted data and discuss data element alignment with other stakeholders in Washington State, such as the HCA, MCO’s, and community services.

The Health Center Roles in the Gravity Project

Health centers can best have their interests represented in the Gravity Project by simply assigning one contact person to provide The Association with the requested materials. These materials will include things like a copy of any current SDoH surveys you are using that are applicable to the current domain, information on programs used for SDOH interventions, of resources you are referring your patients to or wish to refer your patients to, the kinds of diagnosis you think are appropriate for you community.


Health Centers may also participate by providing letters of support for data submission to governing bodies, by joining the Washington State Workgroup, or by participating in a Connectathon.
