The most needed change in our system is a change away from our current fee for service model of paying for health care. Our health insurance companies pay doctors and other providers for every procedure we undergo and for every time we visit the doctor. This means that doctors have incentives to offer lots of procedures and to schedule lots of visits that might not really be necessary. It would make a lot more sense if we had a system (like some being tested) in which providers got a certain amount of money for a given health issue (like for a hip replacement). They would then have an incentive to fix the issue at the lowest cost so they could keep some of the money.
