Gravity Food Insecurity & Housing Instability Data Set Press Release

The Gravity Food Insecurity & Housing Instability Press Release is now LIVE. Please help us share this PR far and wide:

SIREN Coffee & Science 

Join SIREN Coffee & Science, a new virtual conversation series that SIREN is launching to provide a forum for experts to discuss hot topics in health and social care integration. The series of 30-minute live events will start January 22nd and run through June. The events will also be disseminated on SIREN’s new podcast channel, where an introductory episode is already available!

ONC Advancing SDOH Health IT Enabled Tools and Data Interoperability

The Office of the National Coordinator for Health Information Technology has launched a project that focuses on emerging tools for advancing the use of SDOH data in clinical community settings. Data tagging can help enable the movement of sensitive SDOH data. eCDS can enable the integration of SDOH decision-making data into clinical workflows, as supported by specialty practice guidelines, making it more likely that SDOH information will be utilized as a part of care delivery. Learn more about the project here. 

Terminology Process Orientation

The Gravity Project has new educational pieces available in the “Educational and Instructional Materials” section of the confluence! Please check out the new terminology orientation slides and a video describing our adjudication process. 


Please visit and contribute to the Gravity Project SDOH COVID-19 Response page, where you'll find a blog and other resources.  Anyone can view the blog, but a Confluence login is required for those who wish to post blog content.  Click here for instructions on how to request a Confluence login.  Email for login and technical support. 

Social Media

The Gravity Project is now official on social media! We invite you to follow us on LinkedIn and Twitter. We will be using the social media platforms for relevant project and SDOH data integration related communications. Help us spread the word!

Project Overview

The Social Interventions Research and Evaluation Network (SIREN), with funding from the Robert Wood Johnson Foundation and in partnership with EMI Advisors, LLC, launched the Gravity Project in May 2019. The Gravity Project convenes stakeholders across the country through an open and transparent collaborative process where they develop and test consensus-based standards to facilitate SDOH data capture and exchange across a variety of systems and settings of care and social services. 

The Gravity Project seeks to identify data elements and associated value sets to represent SDOH information documented in electronic health records (EHRs) across four clinical activities: screening, diagnosis, goal setting, and intervention activities. The Project deliverables are:

  • Develop use cases that guide the development of standards to support SDOH data capture and exchange; 
  • Identify common data elements and their associated value sets to support the use cases;
  • Develop a consensus-based set of recommendations on how best to capture and group these data elements for interoperable electronic exchange and aggregation;
  • Collaborate with coding and terminology organizations to address coding gaps identified and apply for new codes;
  • Develop, test, and ballot HL7 FHIR Implementation Guide(s) based on the defined use cases and coded data sets; and 
  • Develop Reference Implementation(s) to support real-world pilots and implementations.

Project objectives will be accomplished through bi-weekly virtual meetings and collaborative project product development through the HL7 project confluence page.
