WASHINGTON Physicians generally believe that medical errorsespecially those that cause an adverse eventshould be disclosed to patients, but there is disagreement about the level of detail that should be provided, according to a physician who has studied the issue.
Dr. Thomas Gallagher, associate professor of medicine at the University of Washington, Seattle, told attendees at the annual meeting of the American College of Physicians that physicians are unsure about what to include when they disclose a medical error. But he added that physicians are actively debating the best way to proceed.
"Over the next 5 years, we're going to see very exciting changes," he said. "I think physicians as a profession will be leading the way to set some standards as to how these difficult conversations should go."
Patients conceive of errors broadly and desire full disclosure of harmful errors, while at the same time worrying that health care workers might hide them. In disclosure, they want "an explicit statement that an error occurred," details of what happened, and the implications for their health, he said.
Physicians define errors more narrowly than patients do. They agree in principle with full disclosure and want to be truthful, but perceive barriers to disclosure. "Physicians feared that disclosure could be harmful to the patient," Dr. Gallagher said.
The University of Washington recently surveyed 4,000 physicians about communication with patients, colleagues, and health care institutions about errors.
According to Dr. Gallagher, the survey on error disclosure was sent to 2,000 physicians in Washington State and 2,000 Canadian physicians. The survey, which asked about general attitudes regarding disclosure, had a response rate of 63%.
Respondents were randomized to one of four specialty-specific disclosure scenarios and answered five questions to measure the content of their disclosure. Each question offered actual disclosure language that contained no information, a little information, or full disclosure.
When asked about general attitudes regarding disclosure, 98% of U.S. physicians said serious errors should be disclosed, and more than three-quarters said minor errors should be disclosed to patients. Less than one-third, however, said near misses should be disclosed, Dr. Gallagher said.
But when asked for answers in the specific scenarios, physicians didn't always want to admit that a medical error occurred, he said.
For example, one fictitious scenario involved an inpatient insulin overdose. In the example, a physician wrote an order for the patient to receive "10 U" of insulin, but the "U" in the order looked like a "0," and the following morning the patient received 100 units of insulin. The patient, found unresponsive with a blood glucose level of 35 mg/dL, was resuscitated and transferred to the intensive care unit and is expected to make a full recovery.
Nearly 65% of physicians said they would "definitely" disclose the error, and about 32% said they "probably" would disclose the error, Dr. Gallagher said. When asked how they would explain the situation, 1% said they would tell the patient, "Your blood sugar went too low and you passed out"; 28% said they would say, "Your blood sugar went too low because you received more insulin than you needed"; and 71% said they would tell the patient, "Your blood sugar went too low because an error happened and you received too much insulin."
When asked how much detail they would provide, 11% said they would not volunteer any specific information about the details of the error unless asked by the patient; 36% said they'd tell the patient, "You received more insulin than you needed"; and 54% said they'd tell the patient, "You received 100 units rather than your usual 10 units of insulin."
Dr. Gallagher said that preliminary survey conclusions show that physicians support the concept of disclosure, but are uncertain about the core content of any disclosure. Most would disclose less information about errors that would not be apparent to the patient, he said.
There is accelerating interest in disclosure and growing experimentation with disclosure approaches among health care organizations and malpractice insurers, Dr. Gallagher said, and this goes hand-in-hand with the increased emphasis on transparency in health care generally.
