ABSTRACT
Objective: To assess the evolution of cost per patient/year and the cost per patient/year/drug in patients with rheumatoid arthritis (RA) receiving biological treatments. To analyze and quantify the factors influencing this evolution, such as the optimization of the biological drugs, the use of biosimilars, and official discounts and discounts obtained after negotiated procedures. In addition, to assess specific clinical parameters of disease activity in these patients. Methods: Retrospective, observational study conducted in a Spanish tertiary hospital. Adult patients diagnosed with RA under treatment from 2009 to 2017 were included. Results: 320, 270 and 389 patients were included in 2009, 2013 and 2017, respectively. The patient/year cost decreased from 10,789 in 2009, 7491 in 2013 to 7116 in 2017. In 2017, due to the established competition, discounts of 14% and 29.5% were achieved on etanercept and its biosimilar; 11.5%, 17.8%, 17.9%, 17.3% on adalimumab, certolizumab, golimumab and tocilizumab IV respectively, and 24.6% and 43.1% on infliximab and its biosimilar. The percentage of patients optimized in 2017 was 35.2%. The annual saving in 2017 was 1,288,535 (830,000 due to dose optimization and/or administration regimens, 249,666 corresponding to 7.5% of the official discount and 208,868 after negotiated procedures). Conclusion: The annual cost per patient in RA decreased considerably due to different factors, such as discounts on the purchase of drugs due to official discounts and negotiated procedures, together with the optimization of therapies, the latter being the factor that contributed most to this decrease.(AU)
Objetivo: Evaluar la evolución del coste por paciente/año y del coste por paciente/año/medicamento en pacientes en tratamientos con biológicos con artritis reumatoide (AR). Analizar y cuantificar los factores influyentes en dicha evolución tales como la optimización de medicamentos biológicos, el uso de biosimilares y los descuentos oficiales y los obtenidos tras procedimientos negociados. Además, evaluar parámetros clínicos de la actividad propios de la enfermedad en dichos pacientes. Métodos: Estudio retrospectivo, observacional, realizado en un hospital terciario español. Se incluyeron pacientes adultos diagnosticados de AR en tratamiento con biológicos desde 2009 a 2017. Resultados: Se incluyeron 320, 270 y 389 pacientes en 2009, 2013 y 2017, respectivamente. El coste paciente/año disminuyó de 10.798 en 2009, 7.491 en 2013 a 7.116 en 2017. En 2017, debido a la competencia establecida, se alcanzaron descuentos del 14 y del 29,5% en etanercept y su biosimilar; 11,5, 17,8, 17,9 y 17,3% en adalimumab, certolizumab, golimumab y tocilizumab IV, respectivamente, así como un 24,6% y 43,1% en infliximab y su biosimilar. El porcentaje de pacientes optimizados en 2017 alcanzó el 35.2%. El ahorro anual en 2017 fue de 1.288.535 (830.000 debido a la optimización de dosis y/o pautas de administración, 249.666 correspondiente al 7,5% del descuento oficial y 208.868 tras procedimientos negociados). Conclusión: El coste anual por paciente en AR disminuyó considerablemente debido a diferentes factores, tales como, descuentos en la adquisición de medicamentos debido a descuentos oficiales y procedimientos negociados, junto a la optimización de terapias, siendo este último el factor que más contribuyó en dicho descenso.(AU)

ABSTRACT
Background Spending on biological agents has risen dramatically due to the high cost of the drugs and the increased prevalence of spondyloarthritis. Objective To evaluate the annual cost per patient and cost for each biological drug for treating patients with spondyloarthritis from 2009 to 2016, and to calculate factors that affect treatment cost, such as optimizing therapies by monitoring drug serum levels, the use of biosimilar-TNF inhibitors, and official discounts or negotiated rebates in biologicals acquired by the pharmacy department. Method Retrospective, observational study in a Spanish tertiary hospital. Main outcome Annual cost per patient and per drug. Factors that influenced the costs and socio-demographic parameters and disease activity. Results A total of 129, 215, and 224 patients were treated in 2009, 2013, and 2016, respectively. The annual cost per patient decreased: EUR11,604 in 2009, EUR8513 in 2013, and EUR7464 in 2016. The introduction of new drugs drives economic competition, leading to total savings per drug, with discounts reaching 5.8, 12.4, 16.7, 17.7, 13.7, and 24.8% for original infliximab, etanercept, adalimumab, ertolizumab, golimumab, and secukinumab, respectively, while rebates for biosimilar infliximab reached 31.90% in 2016. The number of patients with optimized therapies reached 47.5% in 2016, which led to cost savings of EUR798,614, in addition to savings from official discounts and rebates of EUR252,706 and savings from optimized therapies of EUR545,908 in 2016. Conclusion The cost of biological treatments declined after official discounts, negotiated rebates, and optimized therapies, leading to a significant decrease in the annual cost per patient. The greatest contribution to economic savings in biological therapy according to our study was biological therapy optimization.
