A no-fault med-mal system would help. But since trial lawyers are much, much more powerful politically than physicians, that's an extreme uphill battle. "Loser pays" would help, too. Doctors leaving states and specialties that are particularly toxic, will also help. In fact, this is the primary thing that has given traction to the tort reform that does exist; states that had been left with critical shortages of neurosurg, OB, etc. Doctors aren't helping anything by staying in jurisdictions where they are being sued constantly. In fact, that just feeds the problem. Although caps on damages are a necessary drop in the bucket, there are no easy solutions in the horizon.
Doctors: By staying in, and moving to, states and cities where med-mal is out of control, you are contributing to the problem. Your med-mal premium is funding it.
