The Social Interventions Research and Evaluation Network (SIREN), with funding from the Robert Wood Johnson Foundation and in partnership with EMI Advisors, LLC, is pleased to invite you to join the Gravity Project. Driven by the growing interest in capturing social risk and protective factor data in health care settings, the Gravity Project brings industry leaders together to identify and harmonize social risk and protective factor data for interoperable electronic health information exchange.The Gravity Project will convene a public collaborative process in 2019 and 2020 to accomplish the following goals for the social domains of food security, housing stability and quality, and transportation access:
  • Develop use cases to support documentation of specific social domains across screening, diagnosis, goal setting, and intervention activities within EHR and related systems;
  • 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; and
  • Initiate development of an HL7® Fast Health Interoperability Resource (FHIR®) Implementation Guide based on the defined use cases and associated data sets that will be finalized in the next phase of work.

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