Cost effectiveness of day stay versus inpatient radiofrequency (RF) ablation for the treatment of supraventricular tachyarrhythmias.

Background : It is well established that radiofrequency (RF) ablation is the most cost effective treatment strategy for patients with supraventricular tachycardia. Previous cost estimates assumed at least an overnight stay following RF ablation. Day stay RF ablation however appears to be a safe alternative. Aims : The aim of this study was to compare day stay and inpatient catheter ablation in terms of cost, efficacy and safety. Methods : This was a retrospective cost effectiveness analysis. The study population consisted of 25 consecutive patients who underwent day stay RF ablation and 25 consecutive patients who underwent inpatient RF ablation (historical controls). Economic analysis was based upon a detailed clinical costing. Results : The mean overall cost per patient of inpatient RF ablation in 1994 Australian dollar values is $2354 (SD, $642) compared with $1876 (SD, $595) for day stay RF ablation (p<0.01). Day stay RF ablation is a cost effective alternative to inpatient RF ablation.
