Abstract

Abstract: Background: The aim is to report healthcare costs in a nationwide cohort of patients with an implantable cardioverter defibrillator (ICD). Methods: This real-life longitudinal retrospective cohort study was based on the French National Health Data System and enrolled all adult patients from the general health insurance scheme implanted with an ICD between 2008 and 2011, and followed them until 2018. Results: Overall, 19, 408 patients were included (mean age 63.8, SD 12.4 years, 81.6% males), with cardiac resynchronization therapy (CRTD), single-chamber, and dual-chamber ICD in 42.5%, 29.8%, 27.7% of patients, respectively. After a mean follow-up of 6.6 SD 3.3 years, 9514 patients (49.0%) died, and 8678 patients (44.7%) had their ICD replaced. The total healthcare cost (all diseases and injuries combined) was €15, 893/patient-year, of which 32% were estimated to be ICD-related. These ICD-related costs were: the implantation hospital stay (representing 59% of the ICD-related costs), ICD replacement (22%), complications' management (11%), and follow-up (9%). Some health events (e.g., a complication during ICD replacement) were counted in two categories, hence the sum of the proportions is >100%. Being under 55 vs. above 75 years old, being treated for hypertension vs. not treated, and receiving a CRT-D vs. a single-chamber ICD each increased the mean total ICD-related cost per patient by approximately 20%; ICD replacement vs. no replacement increased it by 71%. Conclusions: Almost two thirds of the total ICD patients' healthcare costs remained not ICD-related. Advancing the understanding of direct and indirect costs may help improving cost-effectiveness of patients' care pathway. Graphical abstract: Unlabelled Image Highlights: About two thirds of healthcare expenses of ICD recipients are not directly related to the device. An ICD costs about E5000/patient-year. Implantation hospital stay incurs around 60%, replacement 20 %, complications 10 % and follow-up 10 % of the ICD-related costs.
