Efectividad del tratamiento con dexametasona Implante

Abstract

Objetivo: Evaluar la efectividad del tratamiento con dexametasona implante intravítreo (Ozurdex®) en pacientes con edema macular, y analizar el impacto económico de esta opción terapéutica. Métodos: Estudio de cohortes, retrospectivo y analítico realizado en un hospital de tercer nivel. Se incluyeron pacientes diagnosticados de edema macular producido, bien por una retinopatía diabética, o como complicación de la oclusión de la vena central retiniana, a los que se les ha administrado Ozurdex® durante el segundo semestre de 2015. Las variables recogidas fueron: edad, sexo, diagnóstico, ojo tratado, motivo de tratamiento, fecha de inicio, número de administraciones y efectividad de las mismas. Los datos fueron obtenidos de la historia clínica electrónica (Diraya) y analizados mediante LibreOffice Calc. Para el análisis económico se tuvo en cuenta el precio financiado. Resultados: Se incluyeron 64 pacientes diagnosticados de edema macular, con una edad media de 65,41 ± 11,98 años, de los cuales un 63,23% fueron hombres y un 33,76% mujeres. 77/128 ojos recibieron Ozurdex®, obteniéndose respuesta al tratamiento en el 63,63% de los ojos tratados. El 49,35% de los mismos necesitaron una segunda dosis, obteniéndose respuesta favorable en el 42,1%. El intervalo medio de tiempo desde la primera a la segunda dosis fue de 10 ± 5 meses. Para un importe de 785,95 € por implante, y una efectividad del 63,6%, dado que se pusieron 1,2 implantes por paciente/año, el coste/año por paciente en el que el tratamiento fué efectivo es de 1.482,5€. Conclusión: Ozurdex® ha demostrado mejores resultados de eficacia en la práctica clínica respecto a los obtenidos en los ensayos clínicos. En ambos casos, se observó una menor efectividad del tratamiento cuando se realiza mayor número de implantes. Las decisiones sobre qué terapia seleccionar para el tratamiento del edema macular no se basa en el coste del tratamiento sino en su efectividad. Por ello, Ozurdex®, declarado como seguro y eficiente, se encuentra correctamente posicionado como tratamiento de segunda línea.

Purpose: To evaluate the effectiveness of macular edema treatment with dexamethasone intravitreal implant (Ozurdex®) and to analize the economic impact of this therapeutic option. Methods: An analitic and retrospective study developed in a third level hospital. The included patients suffered of macular edema caused by either a diabetic retinopaty or as a complication of the retin central vein occlusion. All of these patients had been treated with Ozurdex ® during the second semester of 2015. Collected variables: age, sex, diagnosis, the treated eye, the cause of the treatment, date of treatment and its effectiveness. This information was obtained from the hospital’s clinical records (Diraya) and analyzed using LibreOficce calc. Results: 64 patients (65,41 ± 11,98 years old) were included in the investigation, 63,23% of which were men and 33,76% women. 77/128 eyes were trated with Ozurdex® and 63,63% of them responded to the treatment. 49,35 % of these patients needed a second dose for the desired effect and 42,1% of them responded to the treatment. These two doses were sepparated by 10 ± 5 months. For an amount of 785.95€ per implant, and an effectiveness of 63.6%, given that 1.2 implants were placed per patient / year, the cost /year per patient in which the treatment is effective is 1,482,5 €. Conclusion: Ozurdex® has shown better results in clinical practice than those obtained in clinical trials. Nevertheless, the effectiveness decreases as the dose grows, and this is a fact in both cases. As the decisions about the treatment are made based on the effectiveness rather than the economical cost, Ozurdex®, which has been declared a safe and efficient product, is, at the moment, correctly positioned as as second choice treatment.
