Resumen

El presente trabajo pretende ilustrar las ventajas de los métodos probabilísticos en la evaluación económica de tecnologías sanitarias. Estos métodos consisten en representar cada uno de los parámetros del modelo mediante funciones de distribución probabilísticas, y ofrecen un análisis de la incertidumbre de los parámetros del modelo mucho mejor que el que se podría llevar a cabo con métodos determinísticos. Los resultados que se obtienen con los métodos probabilísticos se pueden representar mediante una nube de puntos que representa la distribución conjunta de costes y efectos en un mismo plano. Este tipo de información es la que se recoge en la curva de aceptabilidad coste-efectiva, que indica la probabilidad de que una determinada tecnología sanitaria sea coste-efectiva para un determinado valor del AVAC.

Palabras clave:

Abstract

The present article illustrates the advantages of probabilistic methods in health technology assessment. Using probabilistic distributions for parameters, these methods represent parameter uncertainty more effectively than deterministic models. The results of this simulation process represent the joint distribution of cost and effects in the cost-effective plane. More precisely, the cost-effectiveness ratio of each simulation is used to determine whether the ratio is cost effective in relation to the ceiling ratio. This kind of information is represented in the cost-effectiveness acceptability curve, which indicates the probability of a health technology being cost-effective for a particular quality-adjusted life year value.
