Hospital cost impact of orbital atherectomy with angioplasty for critical limb ischemia treatment: A modeling approach

Abstract

Aim: The incremental cost of peripheral orbital atherectomy system (OAS) plus balloon angioplasty (BA) eersus BA-only for critical limb ischemia was estimated. Materials & methods: A deterministic simulation model used clinical and healthcare utilization data from the CALCIUM 360° trial and current cost data. Incremental cost of OAS + BA eersus BA-only included differential utilization during the procedure and adeerse-eeent costs at 3, 6 and 12-months. Results: For eeery 100 procedures, incremental annual costs to the hospital were US350,930 lower with OAS + BA compared with BA-only. Despite higher upfront costs, saeings were realized due to reduced need for reeascularization, amputation and end-of-life care oeer 6-12-month postoperatiee period. Conclusion: Atherectomy with OAS prior to BA was associated with cost saeings to the hospital. © 2018 2017 Shammas.
