To get a blood panel (cholesterol, liver enzymes, hemoglobin A1c, etc) I need to see my PCP who will order those tests from a testing facility. Else my insurance won’t cover it. And I have to schedule a whole visit and pay the copay for the privilege.

Being able to get free tests every 6 months directly from the facility would be an example of a feasibly proactive measure the system could do for us.

Maybe you’re only thinking of a system that will somehow get people to eat healthy and exercise?

I thought this was the main goal of things like preventative medicine. Earlier testing, and more frequent testing allows you to catch things while you still 'feel healthy' so they do not become a chronic problem in the long term. Simple things like tracking weight, blood pressure over time. Add in things like colonoscopies, breast exams, I would say most medicine should be preventative, ie keeping you healthy, rather than reactive, of just trying to try you when you are ill.

This happens in a number of medical systems of countries across the world and is perfectly feasible, usually through premium subsidies for stuff like planned check ups, buying certain types of food and even installing equipment to monitor your driving behaviour. The thinking is that encouraging customers to be healthy reduces premium claims in the future
