A new study published in the British Medical Journal, and summarized by Reuters Health claims that providing more care than necessary may work to lower a doctor’s risk of being accused of malpractice. This phenomena may also be driving up costs . The researchers found that doctors who provided the most costly care between 2000 and 2009 were also least likely to be sued between 2001 and 2010.
Lead author Dr. Anupam Jena, of Massachusetts General Hospital and Harvard Medical School in Boston and his colleagues write in The BMJ that critics of the U.S. malpractice system suggest it encourages defensive medicine, which is when doctors provide more healthcare than necessary in order to stave off lawsuits. “If you ask physicians what’s the number one concern they have when you talk to them about their careers, I would say malpractice will come up as one of their top concerns,” Jena said.
For the new study, Jena’s team examined data from Florida hospitals, looking specifically at whether doctors within seven medical specialties were less likely to face lawsuits in the year following one when they racked up higher than average hospital charges.
“If you look at doctors who spend more in a given specialty, higher spending physicians get sued less often than low spending physicians,” Jena said of the findings.
“The only thing you can say with certainty is there is a correlation between spending and a risk of being named as a defendant on a lawsuit, but that’s a correlation without causation,” said Dr. Daniel Waxman, of RAND Corporation in Santa Monica, California. “Yes, doctors are afraid of lawsuits, but they’re also afraid of looking bad,” said Waxman, who has researched defensive medicine but was not involved in the new study. “There are other motivations to do more as well.”
