Tort reform not the answer, but should be part of the answer
As part of their health care rebuttal, Republicans have focused on tort reform as a way to dramatically reduce costs. As Senator Jon Kyl (R-AZ) said “Everybody knows that there is a huge amount of money that could be saved in health care delivery if we did something to reform this jackpot justice system.” President Obama seems to agree, and has added some tort reform to his health care proposal – although stopping far short of what Republicans want.
The argument for tort reform is that frequent malpractice claims and high awards have forced doctors into prescribing extra, and unnecessary, tests and procedures in order to reduce their potential exposure in a lawsuit. Therefore reforming the malpractice system should reduce those unnecessary activities and reduce costs.
This assumes that these extra procedures are, in fact, unnecessary and add nothing to the value of health care received. It also assumes that many malpractice claims are based on the desire of plaintiffs to ‘hit the jackpot’ and not on genuine malpractice.
Some on the left wing argue that this is far from proven. Ezra Klein notes that Texas, which enacted tort reform in 2003, also has the city with the highest medicare costs per enrollee (McAllen). Indeed Texas as a whole has one of the highest medicare reimbursement rates per enrollee, even adjusting for age, sex, and race. (As a Texan who enjoys my vegetables battered and fried, I wonder if there is a bit of cultural self selection there). So the link between tort reform and cost reduction looks tenuous.
In order for tort reform to have an impact on medical costs, it must either reduce the number (or type) of tests and procedures being prescribed, or reduce malpractice premiums (which would then be passed on to consumers).
This sounds like a theory that can be tested, and this afternoon I was wondering if there is any data which could tell us if tort reform has a meaningful impact on health care costs.
Turns out there is. A recent study looked at the differences in tort reform enacted by various states and correlated that against the costs of employer sponsored health insurance plans over an eight year period. They looked at four different kinds of tort reform:
- caps on pain and suffering awards;
- collateral source reforms (reducing payouts if plaintiffs have already received insurance or other payments);
- joint and several reforms (limiting ability of plaintiffs to sue a deep pocket for the full amount even if they are only partly at fault); and
- caps on punitive damages.
The authors concluded that the first three types of reform lowered insurance premiums of self insured plans by 1-2% (caps on punitive damages had no impact). That sounds like a good outcome and should provide encouragement for further tort reform by the states.
However, for fully insured plans (HMOs) there was no decrease in premiums as a result of tort reform. The authors conclude that HMOs are already doing a good job of monitoring care and avoiding unnecessary activities.
The Congressional Budget Office looked at this study as well as a number of other studies done in the last decade, and have concluded that enacting the four reforms above would likely reduce the total health care costs of the government by 0.5%.
It is not a silver bullet for solving the problems in the US health care system, but is definitely worth pursuing as part of any comprehensive reform.
