OHSU study: Misdiagnosis of MS is costing health system millions per year

"These patients were getting the wrong treatment and missing out on the correct treatment," Bourdette said.

The survey also detailed the emotional and ethical challenges of informing a patient of a misdiagnosis. More than two-thirds of the MS specialists said that informing a patient with a diagnosis of MS that they likely did not have the disease was more challenging than informing a patient of a new diagnosis of MS. And, in an especially surprising finding, about one in seven of the MS specialists said they had sometimes chosen not to inform a patient of their suspected misdiagnosis, citing among their reasons the fact that the patients were not receiving MS treatment, or the potential psychological harm in changing a diagnosis.

The study underlines a significant but underappreciated problem within the U.S. health care system: the dangers, costs and physician challenges associated with misdiagnosed diseases.
