California is 1 of 28 states that restricts nurse practitioners (NPs) by requiring that they practice and prescribe with physician oversight, and it is the only western state with this requirement. A large body of research has linked such restrictions to lower supply of NPs, poorer access to care for state residents, lower use of primary care services, and greater rates of hospitalizations and emergency department visits. Although proponents of scope of practice restrictions argue that physician oversight is necessary to ensure quality of care, dozens of studies demonstrate both that the quality of NP care is comparable to that of physician care, and that there is no difference in the quality of care when there are no physician oversight requirements. Finally, several studies have found that full practice authority for NPs is associated with lower costs of care. This paper describes the regulations that govern the scope of practice for NPs in California and in other states, and summarizes recent research on how these laws impact care.
