RESUMO
Introducción: El objetivo de este estudio es estimar el impacto económico en España de la optimización del tratamiento antirretroviral (TAR) triple en pacientes con carga viral suprimida según las recomendaciones GeSIDA/PNS (2015) y su aplicabilidad en la práctica clínica. Métodos: A partir de los datos de prescripción del TAR de la encuesta hospitalaria 2014, siguiendo las recomendaciones de GeSIDA/PNS de optimización de TAR con grado de evidencia A-I, se desarrolló un modelo farmacoeconómico. Las pautas de optimización, la voluntad de optimización y demás asunciones y resultados del modelo fueron validados por un panel de expertos en la infección por VIH (infectológos y farmacéuticos hospitalarios). El análisis se realizó desde la perspectiva del SNS, considerando el coste farmacológico anual, precio de venta del laboratorio notificado, deducción RD-Ley-8/2010 e IVA. Resultados: El panel seleccionó 6 estrategias de optimización y estimó que en España de los 80.859 pacientes actualmente en TAR triple, 10.863 (13,4%) serían candidatos a optimizar su TAR según estas estrategias, generando ahorros de 15,9M euros /año (2,4% del coste farmacológico del TAR triple). Las estrategias más factibles (>40% del total de pacientes candidatos a optimizar, n=4.556) y asociadas a mayores reducciones del gasto (ahorro entre 653 y 4.797 euros /paciente-año según el TAR triple de partida) serían las optimizaciones a ATV/r+3TC. Conclusión: La aplicación a la práctica clínica española de las principales estrategias de optimización recomendadas en el documento GeSIDA/PNS (2015) generaría ahorros sustanciales, especialmente aquellas basadas en biterapia con ATV+3TC, contribuyendo así al control del gasto farmacéutico y a la sostenibilidad del SNS (AU)
Introduction: The objective of this study is to estimate the economic impact associated with the optimisation of triple antiretroviral treatment (ART) in patients with undetectable viral load according to the recommendations from the GeSIDA/PNS (2015) Consensus and their applicability in the Spanish clinical practice. Methods: A pharmacoeconomic model was developed based on data from a National Hospital Prescription Survey on ART (2014) and the A-I evidence recommendations for the optimisation of ART from the GeSIDA/PNS (2015) consensus. The optimisation model took into account the willingness to optimise a particular regimen and other assumptions, and the results were validated by an expert panel in HIV infection (Infectious Disease Specialists and Hospital Pharmacists). The analysis was conducted from the NHS perspective, considering the annual wholesale price and accounting for deductions stated in the RD-Law 8/2010 and the VAT. Results: The expert panel selected six optimisation strategies, and estimated that 10,863 (13.4%) of the 80,859 patients in Spain currently on triple ART, would be candidates to optimise their ART, leading to savings of 15.9M euros /year (2.4% of total triple ART drug cost). The most feasible strategies (>40% of patients candidates for optimisation, n=4,556) would be optimisations to ATV/r+3TC therapy. These would produce savings between 653 euros and 4,797 euros per patient per year depending on baseline triple ART. Conclusion: Implementation of the main optimisation strategies recommended in the GeSIDA/PNS (2015) Consensus into Spanish clinical practice would lead to considerable savings, especially those based in dual therapy with ATV/r+3TC, thus contributing to the control of pharmaceutical expenditure and NHS sustainability (AU)
