Tort liability and the prohibitive costs of malpractice insurance for OB-GYNs are often cited as drivers of rising rates of cesarean section utilization, with tort reform touted as the only thing that will really lower cesarean rates in the U.S.
In a May 21, 2012 interview with Ob.Gyn.News, Dr. Ronald Stewart applauded the Texas’ 2003 Proposition 12, which resulted in a 19% increase per 100,000 population of practicing physicians.
“Tort reform has been beneficial for all or almost all Texas physicians,” Dr. Stewart said in an interview in advance of the meeting. “I have benefited from lower malpractice premiums and a more favorable liability climate in the state. However, the effect of tort reform in a region is probably not the primary driver for physician recruitment and retention. I believe it is permissive – providing the framework for growing physicians relative to the number of patients being served,” he explained.
Public Citizen’s new report, Medical Malpractice Payments Sunk to Record Low in 2011, doesn’t refute the claim that tort reform in Texas resulted in an increase the number of working physicians in Texas, but argues that Proposition 12 did not lower healthcare costs or produce better care as proponents of the measure claimed it would.
Between 2000 and 2011, the value of medical malpractice payments fell 11.9 percent while healthcare spending nearly doubled, increasing 96.7 percent (both calculations in unadjusted dollars). These figures debunk claims that medical malpractice litigation is responsible for rising healthcare costs, as well as promises that patients should expect savings from litigation restrictions.
Texas, which in 2003 implemented some of the nation’s most stringent restrictions on medical malpractice litigation, has often been cited by tort reform advocates as proof that their prescription works. For example, Rep. Lamar Smith (R-Texas), a co-sponsor of pending legislation (H.R. 5) that would impose a federal $250,000 cap on non-economic damages for medical malpractice claims, wrote in an op-ed that the Texas liability caps have led to an increase in the number of doctors in Texas, which, he said, “means Texans pay less to have better healthcare and more options.”
Actual results in Texas disprove the claims put forth by Smith and other national political figures. Malpractice payments on behalf of Texas doctors declined nearly 65 percent (in unadjusted dollars) from 2003 to 2010, Public Citizen found in an analysis of outcomes in Texas that was published in 2011. But private insurance rates and per-patient Medicare spending in Texas have increased faster than the national average.
The report also supports what citizen advocacy organization Texas Watch wrote in 2011 in the Defending Ourselves against Defensive Medicine series on The Unnecesarean.
Texas voters were given a false choice in 2003: lose their doctors or lose access to their courts. As Texans were going to the polls to vote on an amendment to the state constitution known as Proposition 12, which placed severe and arbitrary restrictions that make it nearly impossible for those devastated by medical negligence to seek justice through our courts, they were inundated by an insurance industry-funded onslaught of slick advertising designed to scare them into thinking that their health care system would collapse if they didn’t give up their constitutional right to seek justice in our courts.
There is research which might support the narrative that tort reform is the key to reducing utilization rates of the cesarean section. A 2009 study showed the malpractice premiums were positively associated with rates of cesarean section and negatively associated with VBAC rates. From the study:
Caps on noneconomic damages were the leading predictor of delivery method among the 10 types of tort reforms investigated. VBAC rates were significantly higher and cesarean section rates were significantly lower in state-years in which caps on noneconomic damages were in force. The effect size increased with the stringency of the cap: caps of $250,000 or less were associated with a 1.92 percentage point (7.97%) higher VBAC rate, caps between $250,001 and $500,000 with a 1.37 percentage point (5.69%) higher rate, and caps above $500,000 with a 1.25 percentage point (5.19%) higher rate.
Noneconomic damages caps were inversely related to rates of cesarean section, although the effects were smaller and were statistically significant for only the lower cap levels. A cap of $250,000 or less was associated with a reduction of 0.48 percentage points (3.68%) in the primary cesarean section rate and a 0.32 percentage point (1.5%) reduction in the total cesarean section rate.
Authors drew the following conclusion from their analysis:
Extrapolating to the national level, our estimates suggest that a nationwide cap on noneconomic damages at the $250,000 level would be associated with approximately 9000 more VBACs, 12,800 fewer cesarean sections, and 8000 fewer primary cesareans per year.
According to this study, a nationwide cap on noneconomic damages at the $250,000 might result in an approximately 1% drop in the cesarean rate.
In theory, Texas might have seen a slight drop in its cesarean rate since 2003 as a result of tort reform. Did tort reform have the effect on the cesarean rate that physicians hoped it would?
