ABSTRACT

Objetivo. Evaluar la costo-efectividad (CE) de la vacuna tetravalente contra el virus de papiloma humano (VPH) en Argentina, desde la perspectiva del sistema de salud. Material y métodos. Se utilizó un modelo dinámico de transmisión para estimar el impacto en la incidencia de cáncer de cuello uterino (Cacu), verrugas y otras lesiones, en los años de vida ajustados por calidad (AVAC) y en costos sanitarios. Resultados. La vacuna podría reducir en 60% el riesgo de muerte por Cacu y en 67% el de padecer verrugas genitales. Comparada con no vacunar, la estrategia de vacunación mostró un beneficio incremental promedio de 0.00234 AVAC por persona a un costo incremental de 2.36 dólares, con una CE de 1007.55 dólares por AVAC ganado. Los resultados demostraron ser robustos en el análisis de sensibilidad. Conclusiones. La inmunización resultaría costo-efectiva, con una CE inferior a un producto interno bruto per cápita (15 009 dólares) por AVAC ganado.


Objective. To assess the cost-effectiveness of the quadrivalent vaccine against human papillomavirus (HPV) in Argentina from the health system perspective. Materials and methods. A dynamic transmission model was used to estimate the impact of the vaccine on the incidence of cervical cancer, warts, and other HPV related diseases; in quality adjusted life years (QALYs); and in healthcare costs. Results. Vaccination could reduce the risk of cervical cancer by 60% and by 67% the risk of genital warts. Compared to a non-vaccine scenario, the immunization strategy showed an incremental benefit of 0.00234 QALY per person at an incremental cost of US$2.36, resulting in an incremental cost-effectiveness ratio of US$1007.55 per QALY gained. Sensitivity analysis proved the robustness of these results. Conclusions. Immunization with the quadrivalent vaccine was a cost-effective intervention in Argentina, and it was far below the threshold of one gross domestic product per capita (US$15 009) per QALY gained.
