New HHS SDOH COVID-19 Collaboration Site

The Department of Health and Human Services (HHS) has announced a new website that will be focused on using SDOH data to fight COVID-19. The core objective of this collaboration site is to identify actions HHS can implement in the next three months that will help HHS:

  • Understand risk patterns and develop social and medical interventions.

  • Manage healthcare capacity before, during, and after COVID-19.

  • Help state and local governments collaborate with academia, private sector, healthcare providers, and civil society.

  • Address shortcomings in data collection and data sharing to fight the pandemic.

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.

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.
