- What: Converted 132 broken wiki links to plain text across 41 health domain files. Added Vida to the Active Agents table in CLAUDE.md. - Why: Leo's PR #15 review required these two changes before merge. - Details: Broken links were references to claims that don't yet exist (demand signals). Brackets removed so they read as plain text rather than broken links. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

SDOH interventions show strong ROI but adoption stalls because Z-code documentation remains below 3 percent and no operational infrastructure connects screening to action
The evidence for SDOH intervention ROI is increasingly strong: food insecurity programs average 85% ROI (range 1-287%), housing programs average 50% ROI (range 5-224%), and one integrated SDOH care model showed 6.9:1 ROI with significantly fewer ED visits at 30 and 60 days. Social isolation alone costs Medicare $6.7 billion annually. A 2025 retrospective study found significantly higher one-year mortality for patients from communities with weaker SDOH profiles.
Yet adoption remains primitive. The Joint Commission and CMS began requiring SDOH data collection in 2024, targeting five health-related social needs: food insecurity, housing instability, transportation, utilities, and interpersonal safety. But Z-code documentation rates sit between 0.5% and 2.4% of encounters, with only 2.03% of patient records including a documented Z-code. The barriers are operational, not evidentiary: unclear responsibility for documentation, absence of workflows connecting screening to referral, and unfamiliarity with codes.
The closed-loop referral platforms (Unite Us with 60 million connections, Findhelp with Best in KLAS three consecutive years) exist but are not yet integrated into standard clinical workflows. CMS is starting to build incentives -- housing instability codes elevated to CC status in 2025, SDOH data factored into risk adjustment models, and a new HCPCS code for standardized risk assessment. But the trajectory from mandated screening to routine SDOH intervention as clinical practice is measured in years, not quarters.
The near-term trajectory: mandatory outpatient screening by 2026, Z-code adoption rising to 15-25% by 2028, closed-loop referral integration in major EHRs by 2030, and SDOH interventions as standard as medication management by 2035. The binding constraint is not evidence or policy but operational infrastructure.
Relevant Notes:
- value-based care transitions stall at the payment boundary because 60 percent of payments touch value metrics but only 14 percent bear full risk -- SDOH is the most acute case of the VBC implementation gap
- social isolation costs Medicare 7 billion annually and carries mortality risk equivalent to smoking 15 cigarettes per day making loneliness a clinical condition not a personal problem -- loneliness as the most dramatic SDOH factor
- continuous health monitoring is converging on a multi-layer sensor stack of ambient wearables periodic patches and environmental sensors processed through AI middleware -- biometric monitoring addresses clinical SDOH (sleep, activity) but not social SDOH (housing, food)
