University of Michigan's policy admitting medical errors reduced costs, study finds

By Tina Reed

A well-publicized University of Michigan policy of apologizing for medical errors effectively decreased liability costs to the health system and didn't lead to additional malpractice lawsuits, an analysis released today concluded.

U-M instituted a policy in 2001 encouraging staff to report medical errors and offer an apology and compensation when the health system found a medical error caused injury. Before that, the health system forwarded all claims to a defense counsel to review and advise whether to settle or go to trial, according to a description from the study.

According to the study, new claims for compensation, liability costs and the amount of time it took to resolve claims after the policy was implemented all went down.

A study released today concluded apologizing for medical errors doesn't drive up malpractice claims.

"This shows that over time, hospitals can afford to do the right thing," Richard Boothman, U-M's chief risk officer and a co-author of the study, said in a release. "It demonstrates what we have believed to be true for some time: the sky won't fall in by pursuing a pro-active and honest approach to medical mistakes."

The study was released today in the Annals of Internal Medicine. It was conducted by researchers at the University of Michigan, Brigham and Women's Hospital, among others.

Among the findings:

  • The median time to resolve a claim dropped from about 16 months to just less than a year.
  • The monthly rate of new claims fell from about 7 per 100,000 patient encounters to about 4.5 per 100,000. The number of lawsuits the health system experienced fell from about 38.7 per year to about 17 after the new program began.
  • The annual spending at the U-M health system on legal defense decreased 61 percent. The average cost per lawsuit decreased from $405,921 to $228,308 after the policy started. Costs did not change significantly for non-lawsuit claims.

There are different possible explanations for the drops, the study authors wrote. They included fewer claims in general and fewer injuries from error because of a safer hospital culture.

It's also possible patients are more satisfied by being offered an apology and an explanation and are less likely to file a lawsuit when they feel the health system is being transparent, said lead author Allen Kachalia, who is medical director of quality and safety at Brigham and Women's Hospital in Boston.

That would be good news, said Sam Watson, senior vice president for patient safety and quality of the Michigan Health & Hospital Association

"I think it makes very good sense. My hope is this is a study that will demonstrate something we all hope to be true," Watson said. "If we're honest and we admit it when bad things unfortunately do happen, it doesn't excuse responsibility, but it changes the conversation."

Often medical lawsuits occur because a patient wants to understand what happened, why it happened and what's being done to prevent it, he said. 

"At the heart of it, that's typically what people are suing for because they don't feel they can get the information another way," Watson said.

According to the study, little data is available on the impact disclosures of medical errors has on liability to health care providers. Some data suggests liability risk may increase when disclosing mistakes.

The study authors pointed out limitations to the research, saying changes in Michigan malpractice law in the 1990s may have impacted the number of paid claims in the state overall during that period anyway.

U-M's policy is driven by a push to change the safety culture, but the study shows clear cost benefits to the practice as well, Boothman said.

"We are all in this together. We support our staff best by being honest about mistakes because without that honesty, we're never fix the problem, other patients may get hurt and we'll expose our staff to that heartbreak again, too," Boothman said in a statement. "Honesty is the key to improving and hurting no one else is the best risk management I can imagine."

Honesty may not always be best in a potential malpractice case. Check out this 2 minute video on YouTube showing an actual case history: <a href="" rel='nofollow'></a>

As an insider, I know that this kind of policy and approach to medicine and health care has been taken up at other large university-based hospitals with similar success. It's a much more important shift in caring for patients than, say, putting a greeter at the ER door or advertising "wait times" on a hospital website.

This policy is really fiction. In the most serious cases, such as the death of a patient, they are not really honest with the patient. It is all smoke and mirrors. As an insider and an expert, I reported an error to the administration that may have lead to the patient's death but the response was largely about a Michigan state law that says that if there was more than a 50% chance that the patient would have died anyway then the patient cannot sue for wrongful death. They missed the point anyway, which was that the problem that lead to the error should be fixed. It was not.

How refreshing it is to hear the breaking of bureaucratic red tape as the reversal of lengthy and costly litigation moves in the right direction for once. I wish this would catch on like wildfire, especially in politics.

Thanks so much for covering these medical news stories and providing the base references to them (i.e. the journal articles). A couple of them have been personally helpful to me. With regard to this specific one, congratulations to the UM system for initiating this policy. It is one that has been discussed on a national level but not implemented in very many places.
