Advance care planning is a process in which capable adults communicate their preferences for medical care in case of incapacitation. Regardless of health status, most adults are interested in advance care planning conversations and prefer providers to initiate these discussions. Primary care nurse practitioners are ideally positioned to lead these conversations but lack knowledge, confidence, and communication skills to do so. This project aimed to develop, implement, and evaluate an educational program for primary care nurse practitioners regarding leading advance care planning conversations with healthy adults. This evidence-based practice project used the Advance Care Planning Self-Efficacy Scale to measure primary care nurse practitioners' self-efficacy after completing a complex educational program. The educational program was developed based on a nationally recognized program incorporating didactic, observational, and role-play learning. The findings of this project indicated that providing complex education was an effective intervention immediately and after 3 months (P = .018 and P = .023, respectively). The results indicate that educating nurse practitioners is an effective intervention for increasing their self-efficacy in leading advance care planning conversations with healthy adults over 3 months, recommending additional intervention at least earlier than 6 months.
