Health care utilization in a nurse practitioner–led atrial fibrillation clinic

ABSTRACT Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is emerging in prevalence with an increasingly aging population. The complex nature of the disease and its association with significant morbidity and mortality has resulted in a call for a new integrative, multidisciplinary approach to AF management. Purpose: Determine if the use of a nurse practitioner (NP)–led AF clinic (NPAFC) can improve care for patients. Methodology: An NPAFC was designed to serve as an independent clinic for standardizing patient care and improving access to care. Baseline patient demographics, care pathway, and interventions were characterized in clinic. Primary outcomes were hospitalizations and emergency department (ER) visits, before and after clinic implementation. Results: Overall, 1,442 patients were enrolled in the AF clinic between January 2016 and June 2018. The mean age at the first AF clinic visit was 68.7 ± 12.6 years, 54% were male, and the mean body mass index was 31 ± 7 kg/m2. Among the patients, 45.2% had paroxysmal AF, 43.6% persistent AF, and 5.5% permanent AF. With an average of 3 ± 3 clinic visits per patient, the number of patients with ≥1 hospitalization decreased by 78% after clinic implementation. Similarly, the number of patients with ≥1 ER visit decreased by 79%, and 22.7% of patients avoided at least one ER visit. Conclusions: The number of patients with ≥1 hospitalization or ≥1ER visit decreased within two years after the implementation of an NPAFC. Implications: Implementation of an NP-led AF clinic in the United States may reduce hospitalizations and ER visits if implemented in an integrative model.
