Simple fix - if a patient’s condition doesn’t improve, the attending doctor and clinic don’t get paid. Bad doctors would be weeded out economically, and healthy economic competition would give medical professionals a reason to really try to advance medicine, rather than just going along with the pharmaceutical companies experimenting on people.
“Simple fix” meet Unintended Consequence
With your plan [if a patient’s condition doesn’t improve, the attending doctor and clinic don’t get paid] any doctor with common sense would just refuse to take cases that didn’t have a great prognosis [that’s likely outcome to those in Rio Linda}.
That way most of their patients would get well, they and the clinic would get paid and the others, well... there’s always Obamacare Clinics, I guess.
