Prevention

Prevention is the least visible and most cost-effective part of health, which is exactly why it is chronically underfunded. Nobody writes a news story about the heart attack that did not happen. Treatment produces gratitude and a bill; prevention produces an absence, and absences are hard to put in a budget request.

It works at three levels. Primary prevention stops a problem from starting: vaccination, clean water, safe housing, tobacco control, physical activity, nutrition. Secondary prevention catches it early, when it is cheap and treatable: blood pressure checks, cancer screening, blood glucose monitoring, developmental screening in children. Tertiary prevention keeps an existing condition from getting worse — the diabetes education, cardiac rehab, and medication management that keep people out of the hospital.

The reason prevention is harder than it sounds is that it competes with everything else in a person's day. A screening that requires a weekday appointment, a car, time off work, and childcare is not equally available to everyone, no matter how free it is. The most effective prevention programs remove steps rather than adding education: bringing the mammogram van to the workplace, putting the vaccine in the pharmacy, defaulting the screening into the visit, making the healthier option the cheaper and closer one.

Prevention also depends on trust, and trust has been unevenly earned. Communities with a history of being experimented on, dismissed, or surveilled by medical institutions have well-founded reasons for caution. Rebuilding that is slow relational work carried out by people with local standing, not a messaging problem to be solved with better graphics.

These conversations cover screening and vaccination, nutrition and movement, workplace and school programs, early detection, and the practitioners trying to make prevention routine rather than exceptional.
