I'm a doctor. So sue me. No, really

The doctors' lobby says capping malpractice suits will make healthcare cheaper.

Flu season has come early and I'm writing far too many prescriptions for Tamiflu. I'm trying my best to adhere to the guidelines set by the Centers for Disease Control for who should get the drug (kids under 5 years of age, or kids who have a chronic illness like asthma or diabetes). But in more than a few instances, I've ignored the guidelines and given Tamiflu to perfectly healthy kids with no risk factors for influenza-related complications.

Part of the reason I'm writing so many extra prescriptions stems from stories about healthy people getting sick with H1N1 and ending up critically ill or dead. One of those stories aired recently on "60 Minutes" -- a healthy high school football player in Arkansas developed a fever after a game. He went to his doctor, who thought he had a garden variety flu and sent him home. Two days later, the boy collapsed and was airlifted to the nearest pediatric intensive care unit. He developed a bacterial pneumonia on top of his H1N1 flu, which led to severe damage to his lungs. He couldn't breathe on his own, so he remains in the ICU on a ventilator.

The H1N1 strain of influenza is no more lethal than any other strain of flu. Mortality is less than 1 percent. Nevertheless, by over-prescribing an expensive drug that has only marginal benefits, I'm unequivocally practicing what is known as defensive medicine. As in, the kind of medicine that protects doctors as much as patients.

Mine isn't an extreme example of defensive medicine. I'm a pediatrician. Obstetricians and emergency room doctors are sued at far higher rates, and would have more dramatic stories to share. But my motivations are the same as theirs: I'm afraid that if I don't do something, one of my patients may get sick or die, and I'll end up in court being asked why I didn't do everything I could have.

Defensive medicine is just one of the supposed systemic ills that doctors, doctors' lobbies and doctors' insurers invoke when they shill for what they call malpractice reform. Proponents of reform say that defensive medicine, frivolous lawsuits and high premiums are behind the surge in healthcare expenses. They insist that malpractice costs are forcing doctors to close their doors and depriving patients of care. Recently, three past presidents of the American Medical Association coauthored an opinion piece for the Wall Street Journal that bundled all of these arguments into an attack on the public option. Their piece attempted to shift the blame for America's healthcare crisis away from private insurers and onto a supposed scourge of ambulance chasers. "The nation needs comprehensive medical malpractice reform," they wrote. "It is the surest and quickest way to slow down the rising cost of healthcare."

Their refrain is familiar to anybody following the healthcare reform debate. The only problem is that it's not true. There's nothing "sure or quick" about changing medical liability laws that will improve healthcare or its costs. Defensive medicine adds very little to healthcare's price tag, and rising malpractice premiums have had very little impact on access to care.

Let's look at the numbers. First, based on the current rhetoric, it's easy to assume we have an epidemic of malpractice suits in America. We don't.

There are many statistics out there, and it's not always possible to make an apples to apples comparison between one study and another. Some surveys cover the nation, some cover one group of states, some cover another cluster, and results vary. But according to the Congressional Budget Office, nationally, between the mid-1990s to the mid-2000s, the frequency of malpractice suits per capita remained stable at about 15 claims per 100 physicians per year. Another report, from the National Center for State Courts, actually shows that the number of cases between 1996 and 2006 dropped 8 percent.

Although the payout per claim has increased, the Justice Department, in a 2007 report about medical malpractice -- in fact, the same report cited by the authors of the Wall Street Journal piece mentioned above -- provided an explanation quite different from an epidemic of lawsuits. "Growing healthcare costs and an increasing effort by many attorneys to litigate only those medical malpractice claims involving severe injuries or wrongful death claims may explain some of these increases," they wrote. Still, even with the rise in payouts, the Congressional Budget Office, using statistics from the government's Centers for Medicare and Medicaid Services, estimates that malpractice costs account for less than 2 percent of healthcare spending. Saving 2 percent of the over $2 trillion we spend on healthcare isn’t going to bend the cost curve.

Next is the question of frivolous lawsuits. Tort reformers push the notion that junk lawsuits dominate the legal system. The Wall Street Journal article cited above refers to studies that show that 80 percent of claims are settled without payment to the patient and that when a case does make it to trial, doctors win 89 percent of the cases.

But the private studies cited often involve small numbers of claims, or focus on a single hospital, insurer, specialty or type of injury, or were commissioned by interested parties, aka the malpractice insurers themselves. The 2007 Department of Justice study cited by the Journal trio covers only seven states, and nowhere does it mention the numbers 80 percent and 89 percent. Repeated attempts to contact and ask one of the authors of the WSJ story about the specific source of their data were unsuccessful. The DOJ report shows that in one state, Illinois, 88 percent of claims were closed without a payout. But for the other states it examined, the number was between 62 percent and 69 percent. Regarding the percentages of cases doctors win, a 2001 analysis by the Bureau of Justice Statistics, examining malpractice trends in the 75 most populous counties in the U.S., put that number closer to 70 percent.

In 2006, researchers from Harvard published a study in the New England Journal of Medicine that was designed to avoid the limits, and the biases, of prior research. What they found kills the notion of frivolous lawsuits. It suggests that most people who sue are suing for good reason.
