HRS 2022: Same day discharge “benefits AF ablation patients”

2862

Results of a study presented at the Heart Rhythm Society’s 2022 annual meeting (HRS 2022, 29 April–1 May, San Francisco, USA) show that the success of intended same day discharge (SDD) improves over time for patients undergoing atrial fibrillation (AF) ablation, according to researchers.

The new care strategy was overseen by allied health professionals (AHPs) and included integrated telehealth monitoring.

The COVID-19 pandemic disrupted routine hospital services around the world, the study team reported. As a result, millions of elective surgical procedures were postponed or cancelled during the first wave of the pandemic in 2020 to allow staff to focus on COVID-19 patients and to decrease the risk of COVID-19 spread.

As AF ablation was considered an elective surgery, many ablation procedures were delayed or cancelled during the height of the pandemic, the researchers noted. As elective procedures resumed, their study sought to determine the success rate of SDD after AF ablation and understand the safety and benefits of the process.

The study was conducted at Brigham & Women’s Hospital (Boston, USA) from December 2020 through November 2021. All patients undergoing AF ablation were considered eligible for SDD, which was protocolised by the AHPs and required case completion by 2 pm, a companion to stay overnight, AHP assessment and next day virtual telehealth visit by AHP. Patients were given cardiac monitoring devices, such as a blood pressure monitoring cuff, to collect objective data following the procedure.

During the study’s timeframe, 602 patients (mean age 64 ± 12; 35% female) underwent AF ablation. In the first third of AF ablation patients (Group 1, n=200), SDD was successful in 64.2% of intended SDD patients (34/53 patients). Among the subsequent 402 patients, SDD was successful in 84.7% of intended SDD patients (94/111 patients).

Compared to the total intended SDD patients (n=164), patients deemed ineligible (n=438) were older (66 vs. 61 years; p<0.01), had greater body mass index (BMI; 29 vs. 28) and higher CHADs-VASc (2.4 vs. 1.8) (p<0.05 for all). Total time from patient arrival to SDD also improved from 12.9 hours to 12 hours.

“The disruptions caused by the COVID-19 pandemic opened our eyes to the essential role virtual monitoring can play in patient management. This notion is particularly important for the EP field at large, where data can be objectively monitored from the comfort of a patient’s home,” said Lauren A Rousseau (Brigham and Women’s Hospital, Boston, USA), who was among the authors of the study. “Our innovative SDD process was a collaborative effort that leverages telemedicine as a way to improve patient experience while maintaining safety, and has the potential to reduce hospital resource utilisation.”

The authors are currently undergoing a cost-based analysis to better understand how SDD impacts hospital resources, and hope the results of this study will create opportunities to evaluate how a SDD process could benefit patients undergoing other procedures in addition to AF ablation.
