FEASIBILITY AND MICRO–COSTING ANALYSIS OF A SAME–DAY DISCHARGE PROTOCOL FOR CATHETER ABLATION OF ATRIAL FIBRILLATION: A PILOT STUDY USING CRYOBALLOON ABLATION

Abstract

Abstract Background Catheter ablation (CA) is a well–established treatment for atrial fibrillation (AF). Due to the ageing population, increasing prevalence of AF risk factors, improving detection methods for AF, and broadening indications for ablation, CA for AF is the most common resource–consuming ablation procedure, strongly impacting waiting list times and healthcare costs. The combination of these factors and limited bed availability led to development of a same–day discharge (SDD) protocol with acceptable efficacy and safety outcomes. Due to the COVID–19 outbreak, we started the SDD pilot project to reduce patient hospital stays and time spent on the waiting list. Objective We aimed to assess our day–case service‘s overall effectiveness and safety. Furthermore, we aimed to evaluate the health–economic impact of a routine adoption of day–case AF ablation. Methods Patients with symptomatic and drug–refractory PAF or early Pe–AF scheduled for de–novo ablation were included in the study protocol if they had the following clinical and non–clinical criteria for an SDD protocol: 1–Clinical factors: a) stable anticoagulation, b) No history of bleeding, c) No systolic heart failure, d) No history of pulmonary disease, e) No interventional procedure within 60 days, f) BMI <35, g) CHA DS –VASc ≤3, h) non–severely dilated left atrium, i) age <65 years old; 2–Non–clinical factors: a) home residence within 50 km, or if more, with an emergency department (ER) reachable within 30 minutes, b) home assistance to the patients the same day of the procedure. Results Fifty–two patients were included in the SDD protocol and underwent PVI with the Arctic Front Advance cryoballoon ablation catheter. Patients were admitted to a cardiac short–stay unit on the day of ablation at 7 am. SDD procedures were carried out in conscious sedation without the presence of an anesthesiologist. After ablation, the patient was admitted to the recovery area for at least 6 hours. Postprocedural echocardiography was performed to rule out pericardial effusion. The bed occupancy cost reduction was 493€/procedure with the SDD protocol (2415€ vs. 1921€). No minor or major complications were observed in the SDD protocol. Conclusion The adoption of an optimized path would lead to a reduction in the length of hospital stays, optimization of beds, a reduction in waiting lists, an accelerating patient access to care and a reduction in patient management costs by optimizing the consumption of resources.
