CARVALHO, Telmo et al. A cost-effective analysis of drug-eluting balloon in highly recurrent stenosis on dialysis vascular access. Port J Nephrol Hypert [online]. 2020, vol.34, n.4, pp.211-216. ISSN 0872-0169.  https://doi.org/10.32932/pjnh.2021.01.099.

Background: The efficacy and cost-effectiveness of drug-eluting balloon (DEB) in vascular access for dialysis remain unclear. Methods: Data obtained from using DEB in highly recurrent stenosis were retrospectively analyzed. These data were obtained from procedures performed in the Vascular Access Center, responsible for attending over 3600 patients from 30 dialysis centers. Highly recurrent stenosis is defined as stenosis having three or more previous interventions and/or associated with early recurrence defined as the last procedure in less than 90 days. Patency and cost-effectiveness were evaluated. Patency was defined as the number of days free of interventions after applying DEB. Cost-effectiveness was evaluated using the incremental cost-effectiveness ratio (ICER) and an estimation of costs per day/patient/year. Results: Data from 37 consecutive procedures on 32 patients were assessed. The average patency time between interventions was 107.22 ± 104.428 days before DEB intervention. After the procedure, the average patency time intervention was 160.27 ± 96.472 days (ρ=0.001). The cost analysis revealed an ICER of 10.37€/ patency day gained. The costs estimation revealed improved patency of 14.5 days/patient/year, and an increased cost of 1028.4€/patient/year when compared to conventional balloon. Conclusions: This retrospective analysis may suggest a benefit of DEB on this highly recurrent stenosis. Although it appears to be more expensive, the increased patency at long term may be considered encouraging.
