Outcomes associated with advanced nursing practice prescriptive authority.

Thirty-three advanced practice nurses (APNs) in 25 different primary care sites in one state participated in a study of the safety and effectiveness of APN prescriptive authority. Data were analyzed on 1,708 patients seen during a 2-month period. Outcomes of care were studied using three different measures as well as patient satisfaction. Evaluation of patient outcome by APN and physician indicated that in 76% of the cases, the patient's condition stabilized or improved. Patients evaluated their own outcomes positively. Participating physicians were unanimous in their evaluation of APN prescriptive authority as beneficial to their patients.
