Abstract
Objectives

The aim of this study was to compare the clinical and economic consequences of using subcutaneous methotrexate (Metoject®) with respect to oral methotrexate in the management of rheumatoid arthritis (RA) in Spain.

Methods

A cost-effectiveness analysis was performed to compare early treatment of RA using a Markov model. The model allowed us to estimate long term efficacy of RA treatment based on data from the literature and expert opinion, and to combine this data with costs of managing RA in Spain. The perspective of the study was from the National Health System point of view, using a time horizon of 5 years and patient lifetime. All costs were expressed in 2009 euros and a 3% discount rate was applied.

Results

The cost (only pharmacologic costs) per quality-adjusted life year (QALY) gained with Metoject® went from 25,173 to 35,807 € at 5 years and from 19,056 to 25,351 € for patient lifetime. When direct costs in RA treatment were considered, it was observed that cost-effectiveness at 5 years went from 29,682 to 42,175 €/QALY gained, and for patient lifetime from 22,514 to 29,848 €/QALY gained.

Conclusions

Additional costs of Metoject® with respect to oral methotrexate would be offset by their improved effectiveness, expressed in QALY, showing that Metoject® could be a cost-effective treatment option for RA in the Spanish Health System assuming a spanish threshold.

Resumen
Objetivos

El objetivo de este estudio ha sido comparar la eficiencia de utilizar el metotrexato subcutáneo (Metoject®) con respecto al metotrexato oral en el manejo de pacientes con AR en España.

Métodos

Se ha realizado un análisis coste-efectividad/utilidad del tratamiento de la AR temprana utilizando un modelo de Markov. El modelo ha permitido estimar la efectividad a largo plazo del tratamiento de la AR en función de los datos de la literatura y de la opinión de expertos y combinarlo con información de los costes en España. El análisis se ha realizado desde la perspectiva del Sistema Nacional de Salud, utilizando un horizonte temporal de 5 años y de toda la vida del paciente. Todos los costes se expresaron en euros del año 2009 y se ha utilizado una tasa de descuento del 3%.

Resultados

La razón de coste (sólo costes farmacológicos) por año de vida ajustado por calidad (AVAC) ganado con Metoject® fue de 25.173–35.807 € a los 5 años y de 19.056–25.351 € para toda la vida. Al tener en cuenta los costes directos de la AR se observó que el coste-efectividad a los 5 años fue de 29.682–42.175 €/AVAC ganado y para toda la vida fue de 22.514–29.848 €/AVAC ganado.

Conclusiones

Los costes adicionales de Metoject® respecto a metotrexato oral se verían compensados por su mejora en efectividad, expresada en términos de AVAC, revelando que Metoject® podría ser un tratamiento costeefectivo para la AR en el Sistema Nacional de Salud según el umbral asumido en España.
