With this evidence-based knowledge the APN will be able to disseminate information to facilitate collaborative change in current practices surrounding staff education, decision making, and self-governance. The APN can then address controversial changes when developing formal policies and procedures, which will increase patient satisfaction and outcomes.

One hundred and nineteen patients (61.3% male), participated in the study. The majority of patients were prescribed warfarin for atrial fibrillation (53.8%). Satisfaction with information about warfarin was inversely related to age (ρ = -0.33, P < 0.01). Patient-reported satisfaction with information pertaining to the question "what is your medicine for?" was significantly associated with anticoagulation control (χ(2) = 7.27, P < 0.01).
