SALINAS-ESCUDERO, Guillermo et al. Cost-effectiveness analysis of prophylaxis vs. ''on demand'' approach in the management in children with hemophilia A in Mexico. Bol. Med. Hosp. Infant. Mex. [online]. 2013, vol.70, n.4, pp.290-298. ISSN 1665-1146.

Background. Hemophilia A is due to a deficiency of factor VIII. Treatment consists primarily of increasing the concentration of FVIII in the blood using replacement products. The aim of this study was to estimate the clinical and economic benefits of prophylactic management with factor VIII in children with hemophilia A in Mexico. We undertook this study to estimate the clinical and economic benefits of prophylactic management (PROF) with factor VIII (FVIII) in children with severe hemophilia in Mexico. Methods. We carried out an economic evaluation of PROF vs. treatment on demand (OD). The strategies compared were management with PROF consisting of recombinant FVIII (rFVIII) 25 IU kg every other day vs. OD management consisting of plasma-derived FVIII (pdFVIII) 40 IU kg. A Markov model was performed with a time horizon of 16 years in patients with severe hemophilia for 2 years, reporting the number of events of bleeding averted (BA). We used a discount rate of 5%. The results are expressed in Mexican pesos (2012). Results. The incremental cost of PROF regarding SD was $7,727,554 pesos. PROF management provides a reduction of 112 BA vs. OD management (162.9 vs. 50.7). Cost per BA was $68,876 pesos. Conclusions. Management with PROF reduces the number of bleeding events facing children with hemophilia A compared to OD management. PROF is a cost-effective alternative to reduce bleeding ($68,876 pesos per BA) according to the willingness to pay established by health authorities in Mexico.
