Cost-effectiveness analysis of treatment with liposomal amphotericin B versus conventional amphotericin B in organ or bone marrow transplant recipients with systemic mycoses

Abstract

Economic appraisal of pharmaceuticals is becoming increasingly important. In a retrospective study of patient records from 58 organ or bone marrow-transplanted patients with systemic mycoses, the cost-effectiveness of treatment with a liposomal amphotericin B formulation was compared with that of conventional amphotericin B. Treatment with liposomal amphotericin B results in fewer adverse reactions, increased life expectancy and higher costs than treatment with conventional amphotericin B. Pricing liposomal amphotericin B at about SKE6000 per patient treatment day will result in an additional cost per life-year gained of about SEK150 000 relative to that using conventional amphotericin B for patients receiving kidney, kidney and pancreas, or pancreas transplants. For liver and bone marrow transplant (BMT) recipients the marginal cost-effectiveness ratio was about SEK195 000 and SEK150 000 per life-year gained. Compared with alternative use of resources in society and health care, use of liposomal amphotericin B rather than conventional amphotericin treatment can be considered cost-effective at the price assumed.
