Cost-effectiveness analysis of dyevert™ Power XT in patients with chronic kidney disease undergoing percutaneous coronary intervention procedures in Spain.

Abstract

To assess the efficiency of Dyevert™ Power XT compared to the standard clinical practice when used for percutaneous coronary interventions (PCI). A Markov model was developed to estimate, over 3-month cycles and a lifetime time horizon, the cumulative costs and health outcomes (life years gained [LYG] and quality-adjusted life years [QALY]) in a hypothetical cohort of 1,000 patients with chronic kidney disease (CKD) 3b-4 and an average age of 72 years.The incidence of contrast-induced acute kidney injury for these patients is 18.89% in routine practice and 7.78% with Dyevert. QALYs were estimated by applying utilities by health state. Transitions between states and utilities were obtained from the literature. Overall all-cause and state-specific mortality were considered. The total cost (€2,022) estimated with the National Health System perspective included cost of the procedure and of CKD management. The parameters were validated by a panel of experts. A discount rate (3% per year) was applied to costs and outcomes. The use of Dyevert yielded more health benefits (34.60 LYG and 5.69 QALYs) compared to the current standard practice (33.11 LYG and 5.38 QALYs). Lifetime cost accumulated at the end of the simulation resulted €30,211/patient with Dyevert and €33,895/patient with current standard clinical practice. The use of Dyevert™ Power XT resulted dominant option, due to its higher effectiveness and lower cost as compared to standard clinical practice and, therefore, a preferred option in patients with CKD stages 3b-4 undergoing PCI in Spain.
