Impact of a dedicated atrial fibrillation clinic on diagnosis-to-ablation time.

Background: Outcomes following catheter ablation (CA) for atrial fibrillation (AF) improve as the diagnosis-to-ablation time (DAT) shortens. Use of a protocol-based integrated care model through a dedicated atrial fibrillation clinic (AFC) may serve to standardize treatment pathways and decrease DAT. Objective: To evaluate the DAT and clinical characteristics of patients with AF referred from an AFC vs a conventional electrophysiology clinic (EC). Methods: Retrospective analysis was completed in consecutive patients undergoing index AF ablation at Riverside Methodist Hospital in 2019 with minimum 1 year follow-up. Patients were categorized based off their CA referral source (AFC vs EC) and where the initial visit following index diagnosis of AF occurred (AFC vs EC). Results: A total of 182 patients (mean age 65 years, 64% male) were reviewed. Patients referred from an AFC (21%) had a median DAT of 342 days (interquartile range [IQR], 125-855 days) compared to patients referred from EC (79%) with a median DAT of 813 days (IQR, 241-1444 days; P = .01). Patients with their index visit following AF diagnosis occurring in the AFC (9%) had significantly shorter median DAT (127 days [IQR, 95-188 days]) compared to EC (91%) (789 days [IQR, 253-1503 days]; P = .002). Patients with DAT <1 year had lower AF recurrence than patients with DAT >1 year (P = .04, hazard ratio = 0.58, 95% confidence interval 0.3418-1.000). Conclusion: DAT is a modifiable factor that may affect CA outcomes. Significant reductions in DAT were observed in patients evaluated through a dedicated AF clinic.

Same-day Discharge after Subcutaneous Implantable Cardioverter-defibrillator Implantation is Safe and Cost-effective.

The feasibility and safety of same-day discharge after transvenous implantable cardioverter-defibrillator implantation is well-established. However, subcutaneous ICDs (S-ICDs) are now increasingly being implanted, and the feasibility, safety, and potential cost savings associated with same-day discharge after S-ICD placement has not been widely investigated. In a small cohort of patients (n = 24) who underwent S-ICD implantation at our institution, 54% were successfully discharged on the same day as their implant procedure. Procedure-related complications were not apparent in this sampling and the reduction in health care costs was high, suggesting this protocol has immense benefit in today's health care environment. As such, same-day discharge of S-ICD patients is appropriate to consider and should receive further attention.
