A significant minority of physicians responding to a national survey disagreed with or admitted not upholding accepted standards of professionalism for open and honest communication with patients. In the February issue of Health Affairs, investigators from the Mongan Institute for Health Policy at Massachusetts General Hospital (MGH) report that, among other findings, one fifth of respondents indicated they had not fully disclosed a medical error out of concern for malpractice lawsuits and about one tenth admitted telling a patient something that was not true during the preceding year.
