These tort reforms are a decent start but not what is really needed. The more likely than not component for standard of care breach has to be assessed by peers who can actually comprehend what that even means in medicine (or at the very least have near equal representation on a jury instead of no representation). They could stop toying around with caps which truly can screw over some patients and instead focus on fair and accurate verdicts instead of the malpractice trial casino system that exists today.
After a generation or so we'd have less scans on the wards and er which means less incidental findings with less procedures to investigate these findings. We could say no to futile care from dialysis in hepatorenal to intubation in the demented aspirating patient that no reasonable peer would think is a 'standard of care.' 50 billion is a vast underestinate of the savings the system would start to see as it started to take hold in the minds of new physicians. Alas it will never happen until the entire system collapses but one can imagine...
