The solution is NOT to decide on one problem at a time to all agree on solving by incremental compromise, or trust free market competition driving what is in reality a non-free market.
Most patients never file a lawsuit, even if things don't go well, and most injuries that aren't deaths or newsworthy are not worth the trouble to an "overburdened" court system itself imposing a lot of burdens.
And the quality life years lost waiting to share a verdict with attorneys ought to count for everyone affected, not just those who spearhead a trial by catastrophe.
I think the solution is to make the practice of medicine more scientific, and less dominated by competitive incentives, but as long as research and development, reform, or even consumer choice, is strictly a cost, that will be considered "too expensive", if not "too risky".

That's a non answer. The medical profession is already embracing evidence-based medicine as well as specific tools such as checklists and EHRs to reduce preventable errors. But there will always be some providers who are simply sloppy or incompetent or even malicious. Nothing else you proposed is actionable, just vague complaints and hand waving.
