Abstract

Background

Atrial fibrillation (AF) is a common arrhythmia associated with significant morbidity, mortality, and healthcare resource use. The prevalence of AF is increasing with a growing and aging population, and timely access to care for these patients is a concern. Nontraditional models of care delivery, such as nurse practitioner (NP)-led clinics, may improve access to care and quality of care, but they require formal assessment. The objective of this study is to assess the effect of NP-led care on the health-related quality of life (HRQoL) of adult patients with AF.

Methods/design

We plan a randomized controlled trial comparing NP-led care vs. standard care. Inclusion criteria are ≥18 years of age, documented nonvalvular AF, willingness to give informed consent, and capacity to complete questionnaires. Patients referred for electrophysiological intervention who are clinically unstable or unable to attend follow-up visits will not be eligible to participate. Patients will be asked for verbal consent during the initial triage phone call from the nurse. Randomization will occur via a secure website. The intervention includes an NP consult, including medical history, physical examination, patient teaching, treatment plan, and follow-up at 3 and 6 months. The control arm involves usual cardiologist consultation with follow-up determined by the cardiologist’s practice pattern. The primary outcome will be the difference in change in Atrial Fibrillation Effect on Quality of Life Survey scores at 6 months between groups. Secondary outcomes will include difference in change of EQ-5D scores at 6 months between groups, difference in composite outcomes of death resulting from cardiovascular cause, hospitalizations and emergency department visits between groups, and satisfaction with NP-led care measured by the Consultant Satisfaction Questionnaire. A sample size of 70 per group will ensure adequate power despite a potential 10% loss to follow-up.

Discussion

Our study will determine the effect of NP-led AF care on HRQoL in patients with AF, as well as measure its impact on relevant outcomes such as death, hospitalization, and emergency department visits. Our findings may have implications for delivery of care to patients with AF.
