ABSTRACT
Dengue and other arboviruses have a considerable economic impact in Brazil. There are vector control strategies for dengue traditional control with pesticides, Incompatible Insect Technique (IIT) with "wMel Wolbachia", and Sterile Insect Technique (SIT).

Objective:

To analyze the cost-effectiveness ratio of the IIT/SIT strategy, compared to traditional vector control with pesticides, for dengue prevention from the perspective of the Brazilian Public Health System (BPHS) as the payer and from the societal perspective in the state of Goiás, Brazil.

Methods:

The two strategies were compared using a decision tree model developed in Amua® software. All estimated parameters were derived from published articles or SUS information systems. The willingness-to-pay threshold (WTP), quality-adjusted life years (QALYs), years of life gained, costs, incremental cost-effectiveness ratios (ICERs), and incremental cost-utility ratios (ICURs) were adopted as study outcomes and parameters. We conducted deterministic and probabilistic sensitivity analyses.

Results:

Form the BPHS perspective, the IIT-SIT strategy is cost-effective, with an ICUR of R$ 72,200 per QALY gained, which is lower than the WTP of R$ 122,064.30/QALY gained. From the societal perspective, the IIT-SIT strategy is dominant (cheaper and more effective than traditional vector control). Sensitivity analyses showed that these results are reliable.

Conclusion:

In the state of Goiás, Brazil, the IIT/SIT strategy is cost-effective from the perspective of BPHS and dominant from the societal perspective, when compared to traditional vector control
RESUMO
A dengue e demais arboviroses têm impacto econômico considerável no Brasil. Há estratégias para controle vetorial da dengue controle vetorial tradicional com pesticidas; Técnica do Inseto Incompatível (TII) com "wMel Wolbachia" e Técnica do Inseto Estéril (TIE).

Objetivo:

Analisar a razão de custo-efetividade da estratégia de TII/TIE, comparada ao controle vetorial tradicional com pesticidas, para prevenção da dengue, na perspectiva do Sistema Único de Saúde (SUS) como pagador e na perspectiva societal no Estado de Goiás, Brasil.

Métodos:

As duas estratégias foram comparadas usando um modelo de árvore de decisão desenvolvido no software Amua®. Todos os parâmetros estimados foram derivados de artigos publicados ou dos sistemas de informação do SUS. Limite de disposição para pagar (LDAP), Anos de vida ajustados pela qualidade (QALYs), anos de vida ganho, custos e razões de custo-efetividade incremental (RCEI) e custo-utilidade incremental (RCUI) foram adotados como desfechos e parâmetros do estudo. Análises de sensibilidade determinísticas e probabilísticas foram conduzidas.

Resultados:

Na perspectiva do SUS como pagador, a estratégia de TII-TIE é custo-efetiva, com RCUI de R$ 72,2 mil reais por QALY ganho, que é inferior ao LDAP de R$ 122.064,30/QALY ganho. Na perspectiva societal, a estratégia de TII-TIE é dominante (mais barata e mais efetiva que o controle vetorial tradicional). As análises de sensibilidade mostraram que esses resultados são confiáveis.

Conclusão:

No Estado de Goiás, Brasil, a estratégia de TII/TIE parece ser custo-efetiva na perspectiva do SUS e dominante na perspectiva societal, quando comparada ao controle vetorial tradicional
