RESUMO

This chapter reviews the current model of HIV patient care and its economic impact. There are clinical and geographical differences in the care HIV patients receive and a need to develop new models of comprehen-sive HIV care has been identified. HIV infection in Spain is an important and expensive public health problem. The main costs are due to an-tiretroviral therapy, indirect costs and the cost of admission, consultation and diagnostic testing. A strong correlation between severity and cost has been identified. Patients diagnosed late have a poorer clinical course, increased mortality and require more medical and therapeutic resources. Early detection of the disease significantly improves the clinical outcomes of patients. The increased number of patients receiving treatment and their progressive ageing will increase costs of HIV healthcare in the coming years.

RESUMO

Objective: Fixed-dose combinations of antiretroviral drugs have meant an important step forward in simplifying treatment and improving compliance and has led to an increased effectiveness of therapy, a viral load decrease and improving the quality of life of patients. The single-table formulation of dolutegravir with abacavir and lamivudine (DTG/ABC/3TC) is a highly efficacious and well-tolerated once-daily regimen for HIV-infected patients. The objective of the study was to assess the incremental cost-utility ratio of the fixed-dose combination of (DTG/ ABC/3TC) versus the combinations emtricitabine/tenofovir/efavirenz (FTC/TDF/EFV), and darunavir/r (DRV/r) or raltegravir (RAL) with emtricitabine/tenofovir (FTC/TDF) or abacavir/lamivudine (ABC/3TC) as initial antiretroviral therapy in patients infected with HIV-1 from the perspective of the Spanish National Health System. Method: The ARAMIS model, which uses a microsimulation approach to simulate the individual changes in each patient from the start of treatment to death through a Markov chain of descriptive health states of the disease, was adapted to Spain. The alternatives used for comparison were the fixed-dose combination of emtricitabine/tenofovir/efavirenz (FTC/TDF/ EFV), and the fixed-dose combinations of emtricitabine/tenofovir (FTC/TDF) or abacavir/lamivudine (ABC/3TC) with darunavir/r (DRV/r) or raltegravir (RAL). The probability of achieving virological suppression by the treatments included in the model was obtained from clinical trials SINGLE, SPRING-2 and FLAMINGO and the costs were expressed in Euros (2015). The model use the perspective of the Spanish National Health System, with a lifetime horizon and a discount rate of 3% was applied to cost and effectiveness. Results: Treatment initiation with DTG/ABC/3TC was dominant when it was compared with treatment initiation with all the comparators: vs. FTC/TDF/EFV (-67 210.71Euros/QALY), vs. DRV/r + FTC/TDF or ABC/3TC (-1 787 341.44Euros/QALY), and vs. RAL + FTC/TDF or ABC/3TC (-1 005 117.13Euros/QALY). All the sensitivity analyses performed showed the consistency of these findings. Conclusions: With the premises considered, treatment initiation with DTG/ABC/3TC STR appears to be the most cost-effective option in ARTnaïve HIV infected patients from the Spanish Health System perspective (AU)


Objetivo: Las combinaciones a dosis fijas de medicamentos antirretrovirales han significado un importante paso adelante en la simplificación del tratamiento y la mejora del cumplimiento, así como hacia una mayor eficacia de la terapia, una disminución de la carga viral y una mejora de la calidad de vida de los pacientes. La formulación de un comprimido único una vez al día con dosis fijas de dolutegravir, abacavir y lamivudina (DTG/ABC/3TC) para pacientes infectados con VIH es un régimen altamente eficaz y bien tolerado. El objetivo del estudio fue evaluar la relación coste-utilidad incremental de la combinación de dosis fija de (DTG/ABC/3TC) versus las combinaciones de emtricitabina/tenofovir/efavirenz (TDF/FTC/EFV) y darunavir/r (DRV/r) o raltegravir (RAL) con emtricitabina/tenofovir (FTC/TDF) o abacavir/lamivudina (ABC/3TC) como tratamiento antirretroviral inicial en pacientes infectados con VIH-1 desde la perspectiva del Sistema Nacional de Salud Español. Método: Se adaptó en España el modelo ARAMIS. Este utiliza un enfoque de microsimulación para emular los cambios individuales en cada paciente desde el inicio del tratamiento hasta su muerte mediante una cadena de Markov de estados de salud descriptivos de la enfermedad. Las alternativas empleadas para la comparación fueron la combinación de dosis fijas de emtricitabina/tenofovir/efavirenz (TDF/FTC/EFV) y las combinaciones de dosis fijas de emtricitabina/tenofovir (FTC/TDF) o abacavir/lamivudina (ABC/3TC) con darunavir/r (DRV/r) o raltegravir (RAL). La probabilidad de lograr la supresión virológica mediante los tratamientos incluidos en el modelo se ha obtenido de ensayos clínicos individuales, SPRING2 y FLAMINGO, y los costes fueron expresados en Euros (2015). El uso del modelo de la perspectiva del Sistema Nacional de Salud español, con un horizonte de vida útil y una tasa de descuento del 3% se, aplicó a coste y efectividad. Resultados: El inicio de tratamiento con DTG/ABC/3TC fue dominante cuando se comparó con el inicio del tratamiento con el resto de comparadores: frente a TDF/FTC/EFV (-67.210,710 Euros / AVAC) vs DRV/r FTC/TDF o ABC/3TC (-1,787,341.44 Euros / AVAC) y vs RAL FTC/TDF o ABC/3TC (-1,005,117.13 Euros / AVAC). Todos los análisis de sensibilidad realizados demostraron la consistencia de estos hallazgos. Conclusiones: Con las premisas consideradas, el inicio del tratamiento con la combinación a dosis fijas de DTG/ABC/3TC parece ser la opción más rentable para el tratamiento de pacientes infectados con el VIH desde la perspectiva del Sistema Nacional de Salud español (AU)
