Doctors should communicate their qualifications and training to patients, and a new law in Maine now requires health care professionals to tell patients their credentials. It is the fourth such law that has been enacted this year. This truth in credentialing requirement is based on the American Medical Association's "Truth in Advertising" model bill. The new law requires that all health care professionals display their education and licensure so patients know who is providing their care. Physicians and non-physicians must wear identification that displays their name, type of license and staff position. When advertising their services, physicians must communicate their licensure status and not promise more than what their education, training and licensure allow.
