Microcosting analysis of haematopoietic stem cell transplantation and chemotherapy with intermediate doses of cytarabine in the treatment of acute myeloid leukaemia

Abstract

BackgroundAcute myeloid leukaemia (AML) is considered a costly disease. Depending on the risk stratification, the patient may receive consolidation with cycles of intermediate doses of cytarabine, auto-HSCT or allo-HSCT according to availability in each service and the availability of a compatible donor. Literature data indicate that safety and effectiveness do not differ between consolidation therapy with intermediate-dose cytarabine or auto-HSCT, and so the cost can help physicians and health managers in their choice. MethodThe cost of the second consolidation was compared in 18 to 60-year-old patients with de novo AML who were included in the International Consortium of Acute Myeloid Leukaemia (ICAML) protocol. Patients treated with auto-HSCT or intermediate doses of cytarabine (IDAC) were analysed during four years using the microcosting methodology. ResultsThe mean costs for auto-HSCT and IDAC were BRL$ 34,900.95 (range: 23,611.36–41,229.59) and 15,231.64 (range: 6,546.36–23,253.53), respectively. The mean duration of in-hospital stay was 88.4 (93–133) and 94 (50–153) days, respectively. The mean cost of the four cycles of treatment was BRL$ 114.212,78 for auto-HSCT and BRL$ 121.980,93 for the chemotherapy group. Regardless of the type of treatment, the input that had the greatest economic impact was hospital admission, mainly due to infections. ConclusionAuto-HSCT had a lower average cost per patient and hospitalization rate than chemotherapy.
