In 18 states, plus the District of Columbia, nurse practitioners are allowed to treat patients and prescribe medications without a doctor’s involvement. Lawmakers in a number of other states are pushing for similar changes to so-called "scope of practice" laws that determine what nurse practitioners can do for patients. Proponents argue expanding the roles of nurse practitioners can address what has become a major problem: a shortage of primary care doctors. But many physicians say a team-based approach that includes at least one medical doctor is better for patients. Please join us to discuss the role of nurse practitioners.
