Inguinal vascular complications after ablation of atrial fibrillation: An economic impact assessment

Abstract

Ablation of atrial fibrillation (AF) is recommended in the guidelines as a Class Ia/IIa indication. However, associated complications should not be dismissed; specifically, inguinal vascular complications (IVC). Although IVCs are generally considered trivial, they represent an economic burden for the procedure-performing hospital and the patient. Therefore, the ability to monitor and ultimately minimize potential complications is of considerable interest. An economic model was developed to calculate the economic impact for certain IVC-types from a large German single-centre perspective in 2015 and 2016. Twenty-nine of 1040 (2.79%) and 48 of 1152 (4.17%) AF-ablation patients had documented IVC in 2015 and 2016 (P = 0.08), respectively. Inguinal vascular complications that required invasive treatment (thrombin, intervention, surgery) occurred in 0.58% of the 2015 and in 0.87% of the 2016 AF-ablation cases. The expected excess costs (incorporating direct costs, benefit lost adjusted for reimbursement) per patient treated with AF-ablation were 139.54€ and 153.31€ in 2015 and 2016, respectively. This was mostly driven by opportunity costs, which could reach 15 544.71€ for certain IVC. Sensitivity analysis revealed the probability of occurrence, length of stay of certain IVC types, and the revenue per day influenced the expected costs per AF-ablation patient. Even relatively benign complications such as IVC can result in considerable cost increases. Therefore, measures to reduce them should be established and implemented.
