SteveH,
Thanks for the lengthy reply and all the research.
I cannot entirely buy the conclusions in the first article you linked (Baker), because it is long on opinon, short on data. He cites a 1970 California study, but waves airily over the subsequent years. "First, we know from the California study, as confirmed by more recent, better publicized studies, that the real problem is too much medical malpractice, not too much litigation." Why not cite the more recent studies? Bottom line on Baker: He has an axe to grind, eliminating malpractice itself, and a book to sell.
Nevertheless, I found one very useful thing in Baker's article: "In 2003...Doctors, hospitals, and other health professionals paid only about $11 billion in medical malpractice insurance premiums." What this means is that the boundary limit for savings for malpractice insurance is $11 Billion a year. Since insurance companies are in it for profit, we can also deduce that total payments for malpractice awards and cost of fighting malpractice suits in 2003 was something less that $11 Billion. Even after inflation, it's probably less than $15 Billion today. That is very useful information.
The Harvard study deals only with frivolous/meritless lawsuits. That is only a subset of the (perceived) problem, and I agree that our court system is probably capable of weeding out quite a few of the claims which have no merit. The larger part of the problem, (I think) is of awards being granted far out of proportion to the injury sustained...punitive and pain and suffering. My experience is limited to anecdotes, not statistics, but I do know of cases where the actual damages were dwarfed by the punitive award. Interviews with the jurors showed that the high award was due to a desire to do something nice for the patient, who faced an impaired life, and do something mean to the doctor/hospital who has lots of money. It was Even a few of these kinds of cases has a multiplier in cost of insurance and defensive medicine.
The third part of the equation is defensive medicine itself, which we have discussed above. I still am not convinced that the 0.3% factor used by the CBO is supported in anything but "surmising" on their part. I wish there were facts.
Let me say again what I said in the first posting. If health reform is really wanted, it will be paired with tort reform so as to bring aboard support from Republicans and Blue-dog Democrats. You and I can debate how much it will save, but its inclusion would probably guarantee passage of a bill.
Thanks again for the exchange of views. I learn from you each time we post.
