Évaluation des coûts de traitement de la tyrosinémie de type I
Introduction : Tyrosinemia type I is a severe genetic disorder. Symptoms include hepatic,renal and neurological manifestations. NTBC became the first-line therapy in 1994. This drug has led to a drastic improvement in the prognosis. Objective : To evaluate direct medical costs of healthcare services related to the treatment for this disease. This economic evaluation was conducted among the 3 following groups: an historical group of untreated patients, a late-treatment group and an early-treatment group with NTBC. Methods : The costs-consequences analysis includes costs incurred by hospitalizations, medical services and related treatments. Data are derived from the RAMQ and Med-Echo administrative databases and patients’ hospital charts. Results : NTBC treatment is associated with a significant reduction in hospitalizations, intensive care unit stays and liver transplantations. The cost of hospitalizations is significantly less for both treated groups (13,979 $, 6,347 $ and 673 $ per year-patient for the historical group, the late-treatment and the early-treatment group, respectively; pvalue< 0,0001). The cost of hospitalizations for liver transplantations per year-patient is 4,676 $ for the historical group and 3,567 $ for the late-treatment group. The cost of NTBC per year-patient is 66,965$ and 51,493$ for the late-treatment and the earlytreatment groups, respectively. Conclusion : These results demonstrate that NTBC treatment results in a major reduction in healthcare resources utilization, liver transplantations and associated costs.
