Análisis coste-utilidad del modelo de unidad de terapia intravítrea (UTI) frente a la administración tradicional de terapia intravítrea

Abstract

AimTo compare the effectiveness and costs of the implementation of the intravitreal therapy unit model, endorsed by the SERV, SECA, SEO and SEDISA, compared to the usual procedure. MethodAnalytical decision model that compares an UTI-type healthcare organization with four usual practice scenarios in Spain, in terms of quality-of-life results due to loss of visual acuity and the use of resources. The probability, cost, and quality-adjusted life years (QALYs) were estimated for each scenario proposed. A univariate sensitivity analysis was performed for each of the parameters used in the model. ResultThe model showed that from any of the initial scenarios of the usual practice, transitioning to the UTI-type implementation improves the quality of life of patients and requires lower cost. UTI-type is dominant respect usual practice. The sensitivity analysis showed that the results would not change sign with the variation of any starting variable. ConclusionsShorten suspicion-needle times is key to maintaining functional vision in patients requiring intravitreal treatment. The UTI-type model seeks the efficiency of ophthalmology services and can produce savings that vary between €175 and €85 per patient attended per year.
