^Little other than when the cost to fix something seriously broken outweighs he costs of keeping it from breaking to begin with.
My GF's "new" medical plan, from her employer, has a "wellness" clause. She's now required (among other things) to get an annual physical and see a dentist at least every 6 months for "routine" checkups.
If she doesn't, she faces a significantly higher annual medical deductible fee - plus higher co-payments for most covered medical treatments.
There's also a bunch of rules about completing recommended therapies and taking prescribed medications - or else additional $$$ out of your own pocket.
So maybe the medical profession doesn't have a direct incentive - although I do know many dedicated and caring doctors who act in a responsible fashion towards their patients.
But the insurance companies paying the doctor's fees - and the businesses paying for those insurance plans - are certainly beginning to realize they have one.
All the more reason to continue to shift jobs to the "industrial slave" nations as quickly as possible.
I'm quite certain that individually, there are a lot of medical professionals that are quite sincere about helping people.
I'm not convinced that they are working inside of a system that is compatible with helping people...
e.g. It's illegal to make medical claims about treatments that have been around for hundreds or thousands of years and that have been tested through time and known to work? Illegal to make medical claims about food?
Nah - the system is entirely geared to keep people sick and on drugs. There is zero financial incentive to help keep people healthy.
For the insurance companies, as long as they charge higher premiums and continue to pay out, they have every incentive to keep people sick. After all, you wouldn't want to be sick without insurance, would you?
Perhaps I'm a bit cynical. I just don't see a system that works. When proven therapies are excluded and mocked, there's something very wrong.
And that's before we even get into the billions of dollars in fines that big pharma pays for their criminal behaviour...
