Cost-Effectiveness of Recombinant Activated Factor VII as Adjunctive Therapy for Bleeding Control in Severely Injured Trauma Patients in Germany

摘要

Purpose: The purpose of this study was to assess the cost-effectiveness of recombinant activated factor VII (rFVIIa) as adjunctive therapy for the control of bleeding in patients with severe blunt trauma injuries in Germany. The primary outcome measure was incremental cost per quality-adjusted life-year (OALY) gained. Materials and Methods: We developed a cost-effectiveness model based on patient-level data from a 30 day international, randomized, placebo-controlled phase II trial. The data were supplemented with secondary data from the German Trauma Register and German life tables to estimate lifetime costs and benefits. We assumed that the non-significant difference in mortality observed in the phase II trial of 5% in favor of rFVIIa could be verified in the ongoing, much larger follow-up trauma study. We adopted the perspective of third-party payers in Germany, and included all trauma-related healthcare costs. Results: The incremental cost per OALY gained with rFVIIa relative to placebo was ?29,451.The probability that this was below ?30,000 and ?40,000 was 51 and 58%, respectively. The estimates were sensitive to the differences observed in mortality and the applied discount rate. Conclusions: Based on preliminary evidence from a phase II trial, we conclude that, relative to placebo, rFVIIa may be a cost-effective therapy from the third-party payer perspective in Germany.
