How FHIR Powers SDOH Data Exchange in Modern Healthcare
Social factors—housing, food access, transportation, income, and safety—shape more of a patient’s health outcomes than clinical care alone. Yet most clinics and hospitals struggle to capture, store, and share Social Determinants of Health (SDOH) data efficiently.
FHIR changes this.
FHIR provides the structure and interoperability needed to move SDOH data across EHRs, social service agencies, community organizations, and care coordination platforms. With FHIR, healthcare teams can turn SDOH screening into measurable action, reduce gaps in care, and improve outcomes for high-need patients.
Why SDOH Data Exchange Matters
Healthcare teams know SDOH issues are real—missed appointments due to lack of transport, medication non-adherence due to food insecurity, and unmanaged chronic conditions caused by unstable housing.
But without structured data exchange:
- Important SDOH details get buried in free-text notes
- Social workers operate in isolation from clinical teams
- Providers don’t see whether referrals to social services were completed
- FQHCs face difficulties reporting on SDOH screening metrics
- Care plans miss key context that affects patient outcomes
SDOH is not just “extra information”—it determines whether care plans succeed.
FHIR provides the digital infrastructure to make SDOH data actionable.
How FHIR Enables SDOH Data Exchange
FHIR provides standardized resources and coding systems (LOINC, SNOMED CT, Gravity Project concepts) to capture and share SDOH information with clarity and consistency.
1. FHIR Standardizes SDOH Data Into Structured Fields
SDOH cannot live in “free text” if you want to automate referrals, measure outcomes, or coordinate care.
FHIR solves this by defining structured resources for:
- Food insecurity
- Housing instability
- Transportation access
- Utility needs
- Financial strain
- Interpersonal safety
Why this matters:
Clean, structured SDOH data can trigger workflows, populate dashboards, and move across systems without manual interpretation.
Example:
A positive food insecurity screening (LOINC 88122-7) automatically flags a care manager and updates the patient's risk profile.
2. FHIR Connects Clinical Teams with Community Partners
Using FHIR APIs, clinics can securely share SDOH needs with social service agencies and receive updates backclosing the loop.
Why it matters:
Clinicians finally see whether referrals were accepted, scheduled, or completed.
Example:
A patient screened for housing insecurity is referred via FHIR to a community housing partner, who updates status (“accepted,” “appointment scheduled”). The update flows back into the clinic’s EHR automatically.
3. FHIR Supports the Gravity Project SDOH Standards
The Gravity Project defines nationally recognized SDOH codes and FHIR profiles.
Using these ensures compatibility across:
- EHRs
- Referral platforms
- Social service databases
- Payers
Why it matters:
It avoids custom coding that breaks integrations later.
Example:
Housing status is recorded using Gravity-aligned SNOMED CT concepts, ensuring every system interprets it consistently.
4. FHIR Resources Act as Workflow Triggers for SDOH Interventions
Each SDOH screening, diagnosis, or service request can trigger automated workflows.
Examples:
- A new Condition for homelessness triggers a care plan task
- A ServiceRequest for food assistance notifies a care coordinator
- A Task resource shows referral progress
- A Goal resource tracks improvement over time
This allows SDOH care to be proactive and measurable.
5. FHIR Enables Closed-Loop Referrals for Social Services
Closed-loop referrals are often the hardest part of SDOH care.
FHIR simplifies this by:
- Sending structured service requests
- Receiving updates
- Tracking acceptance and completion
Why it matters:
Clinicians no longer must call community partners.
Care managers no longer guess whether services were delivered.
Example:
A transportation assistance referral is auto updated when a ride is scheduled or cancelled.
Where FHIR Delivers the Biggest SDOH Impact
SDOH Screening Automation
- Auto-record SDOH screening responses
- Trigger interventions for positive results
- Avoid manual data entry into EHRs
Impact: Better documentation, faster follow-up.
SDOH Referral Management
- Track referral status in real time
- Connect community orgs directly via APIs
- Provide clinicians with fast updates
Impact: Higher referral completion rates.
Risk Stratification & Care Planning
- Combine clinical + SDOH data for stronger risk scoring
- Automate care plan adjustments
- Identify high-need patients earlier
Impact : Better chronic condition control.
Population Health Reporting
- Structured SDOH fields simplify reporting
- Gravity codes improve analytics accuracy
- Reduce manual chart review time
Impact: Easier compliance with SDOH reporting standards.
| SDOH Use Case | FHIR Resource | How It Helps |
|---|---|---|
| SDOH Screening | Observation | Stores structured Gravity-aligned screening results |
| SDOH Problems | Condition | Documents SDOH diagnoses like housing or food insecurity |
| Community Referrals | ServiceRequest | Sends SDOH referrals to external partners |
| Referral Tracking | Task | Tracks referral acceptance, progress, and completion |
| Care Plans | Goal / Care Plan | Represents patient goals and action plans |
How Organizations Can Start Using FHIR for SDOH
1. Enable FHIR resources that support SDOH use cases
Start with Observation, Condition, ServiceRequest, Care Plan, Goal, and Task.
2. Use Gravity Project SDOH profiles
Ensures interoperability with national standards.
3. Integrate with community-based organizations
Use FHIR APIs for bi-directional updates instead of faxes and calls.
4. Automate SDOH-driven workflows
Set triggers for screening results, diagnoses, or referrals.
5. Build dashboards and population insights
Structured SDOH data improves analytics, risk scores, and reporting accuracy.
Conclusion
SDOH issues can only be addressed when they are visible and actionable. FHIR provides the infrastructure to make that possible—turning screenings into coordinated care, referrals into measurable outcomes, and community partnerships into closed-loop workflows. If your organization wants to advance SDOH care, start with FHIR.
It’s the foundation that makes real integration possible.
