**TITLE:** Precision & Preventive Health Systems: Delivery Models, Technology Platforms, and Pathways to Scale
---
**KEY FINDINGS:**
- **Geisinger's Fresh Food Farmacy Program** serves 2,500+ patients with Type 2 diabetes across 11 sites in Pennsylvania, providing weekly produce prescriptions alongside health coaching. Outcomes show average HbA1c reductions of 2.1 percentage points, with estimated cost savings of $24,000 per patient annually in avoided hospitalizations. Cost-per-participant runs approximately $2,400/year. Technology enablers include EHR integration for patient identification, predictive risk scoring, and outcome tracking dashboards (Geisinger Health, 2023).
- **Kaiser Permanente's Total Health Assessment Platform** reaches 8.2 million members annually through an integrated digital health risk assessment linked to automated care pathways. The system uses ML-based risk stratification to route high-risk patients to intensive prevention programs. Their cardiovascular prevention initiative reduced heart attacks by 24% across their population between 2008-2020, with cost-per-assessment under $15 and downstream interventions averaging $180-$400 per member for lifestyle coaching programs (Kaiser Permanente Institute for Health Policy, 2022).
- **NHS England's Diabetes Prevention Programme** is the world's largest at-scale prevention program, having enrolled 1.1 million people since 2016 with 900,000+ completing the program. Delivered through a hybrid digital/in-person model via contracted providers (Liva Healthcare, Oviva, Second Nature), cost-per-participant is ÂŁ295 ($370). Outcome data shows 3.3kg average weight loss at 12 months and 7% reduction in progression to Type 2 diabetes. Digital-first delivery now accounts for 65% of participants, enabling geographic scale (NHS England, 2024).
- **Livongo (now Teladoc Health) Diabetes Management Platform** serves 1.2 million members across 5,000+ employer clients. The connected glucose monitoring + AI coaching model demonstrates 18.4% reduction in diabetes distress and 0.8 percentage point HbA1c reduction. Cost-per-member-per-month ranges $75-150 depending on contract structure, with employers reporting $83 PMPM savings in medical claims. Key technology: cellular-connected devices eliminating app friction, real-time data transmission, and ML-driven intervention timing (Teladoc Health Outcomes Report, 2023).
- **All of Us Research Program (NIH)** has enrolled 750,000+ participants with 500,000+ providing genomic data, creating the most diverse precision medicine dataset in the U.S. The platform enables polygenic risk score development now being piloted in 10 health systems for conditions including coronary artery disease, breast cancer, and Type 2 diabetes. Cost-per-participant for full sequencing and longitudinal data collection is approximately $1,200. Early implementation studies show 3x increase in statin initiation among high-PRS individuals when results are returned with clinical decision support (All of Us Research Program, 2024).

**WHAT TECHNOLOGY ENABLES:**
| Capability | Enabling Technology | Current Maturity |
|------------|---------------------|------------------|
| Risk Stratification | ML models on EHR data, polygenic risk scores | High (deployed at scale) |
| Continuous Monitoring | CGMs, wearables, connected devices | Medium-High (cost barriers) |
| Behavior Change Delivery | Digital therapeutics, AI coaching, async messaging | Medium (engagement decay) |
| Care Coordination | EHR integration, automated referral pathways | Low-Medium (interoperability gaps) |
| Outcome Measurement | Claims integration, patient-reported outcomes platforms | Medium (attribution challenges) |
---
**DELIVERY CONSTRAINTS:**
1. **Reimbursement Misalignment:** Fee-for-service models pay for treatment, not prevention. Only 3% of U.S. healthcare spending goes to public health/prevention (CMS, 2023). Value-based contracts cover <40% of commercially insured lives.
2. **Data Fragmentation:** Average U.S. patient has records across 19 different providers. HL7 FHIR adoption remains incompleteâonly 60% of hospitals can send/receive/integrate data (ONC, 2023). Prevention programs cannot access complete risk pictures.
3. **Engagement Decay:** Digital health programs show 60-70% drop-off within 90 days. NHS DPP completion rate of 82% required intensive human touchpoints; purely digital completion rates average 45-55%.
4. **Equity Gaps:** Digital-first models exclude 15% of adults lacking broadband access. Precision medicine datasets remain skewedâAll of Us is notable for diversity, but most PRS models were developed on 80%+ European-ancestry populations, reducing accuracy for others.
5. **Workforce Constraints:** Health coaching, community health workers, and care navigators are essential for high-touch prevention but face 25-30% annual turnover and limited training infrastructure.
