How to create a prevention-centered health system
- Prevention becomes a system when accessible care, healthier environments and sustained support become part of everyday life.
Why is a new system needed?
- While treating illness is essential, many of the existing health care systems are predominantly designed around treating illness (at great public expense) instead of preventing illness.
- Due to the high costs of health insurance, many people do not have it.
- There is a largegap between identifying a health risk and helping someone address it.
- A warning accomplishes little when people cannot afford nutritious food, reach a clinic or obtain ongoing support. Investigate payment incentives alongside housing, pollution, working conditions and service access.
What does it look like?
- A connected network of primary care teams, community health workers, public health agencies, schools and local services.
- Prevention includes vaccination, tobacco control, appropriate screening, early treatment and healthier living conditions. Emergency and specialist care remain essential.
How does it work?
- Teams identify local needs, provide evidence-based interventions and follow up consistently.
- Funding covers outreach and continuity. Referral systems connect patients with practical support. Outcome measures account for patient needs and protect access for people with complex conditions.
What are the benefits to the builders?
- Clinicians and community workers receive funded time for sustained care. Providers and public agencies can coordinate services and reduce some avoidable demand.
- Financial savings require evaluation: an intervention can improve health and offer good value without reducing total spending.
What are the public benefits?
- Fewer preventable illnesses and complications, earlier help, improved quality of life and potentially narrower health inequalities.
- Results should show who benefits—and who remains excluded.
What steps are needed for success?
- Choose one priority using local data; design services with residents; fund staff and referrals; remove access barriers; protect patient information; establish baseline measures.
- Evaluate health outcomes, participation and costs over an appropriate period.

United States National Diabetes Prevention Program: An operating network providing structured lifestyle support. The original research underpinning it found a 58 percent relative reduction in diabetes incidence among high-risk adults. Individual programs should be evaluated on their actual results. CDC
