Based on San Diego’s local CIE development and evolution of data integration and interoperability capabilities, this presentation focuses on the role social services has played in key initial successes, driving use-cases, and data models that further true communitywide care coordination and trauma-informed care. We debunk myths about social services capabilities to participate in data interoperability, HIPAA compliance, and the use of billing codes within a health care setting. We also focus on social services agencies’ expertise around SDoH data, and highlight the ways they are leading the way for holistic, person-centered data models. Without this perspective, we lose the expertise gained through years of providing direct service to people with complex care needs and intersectional identities.
