There are many types of health care professionals. Traditional roles and responsibilities held by physicians and nurses have changed, along with the expansion of technology and the demand for health care services. The education, certifications, and licensures for types of health care practitioners differ, as does their scope of practice  (what they are allowed by law to do for patients). The December 5, 2012, issue of JAMA is a theme issue on medical education.
