I think any attempt to better healthcare through litigation and regulation is misguided.
For one things, regulations will only serve to handcuff healthcare providers, hospitals, and insurers. In addition, I think it is hopeless to try to regulate effectively and efficiently in an industry like medicine that is so tied with the state-of-the-art. Patient care is a constant educational process, and the inability of policy to keep up with patient needs is a major concern.
Also, litigation creates a silo mentality among doctors and insurers; this mentality encourages the hiding of mistakes. In a field as critical as healthcare, mistakes cannot be hidden. They must be recognized and fixed. I do think malpractice lawyers play an important role in our healthcare system -- poor care must be punished. However, the effect that malpractice lawsuits have on the psyche of doctor-lawyer relations helps no one.
I think an open-ended move would be best. Set up a system of care whereby the quality of service (measured in terms of health improvement, decreased mortality, etc.) would dictate compensation. Instead of having a system where poor care is sometimes more profitable, we need to incentivize the progress towards good health.
Sure, there are lots of details that need to be worked out (how to place values on care and quality of life, for example), but I think that they can be.
Sorry, I might have gone off on a tangent. Hopefully, I contributed something of interest.
