About 33% did not completely agree with disclosing serious medical errors to patients.
Nearly 20% did not completely agree that physicians should never tell a patient something untrue.
Almost 40% did not completely agree that they should disclose their financial relationships with drug and device companies to patients.
More than 10% reported having told patients something untrue in the previous year.
