OBJECTIVES

: To evaluate the cost-effectiveness of an Eco-systemic Intervention versus the conventional management for the control of diseases transmitted by Aedes aegypti in Girardot-Colombia, 2017.

METHODS

: A complete economic analysis was carried out in Girardot, comparing the control of the vector with the intervention of the ecosystem approach versus the regular program. Outcome was measured as number of dengue cases. We adopted the perspective of society and used a time horizon of one year. The effectiveness of the intervention was obtained from a community trial and the direct costs were obtained from clinical records, which were validates by a group of experts. We adopted the human capital approach to estimate indirect costs, which were obtained through a survey applied in the community. The incremental cost-effectiveness ratio was estimated as the additional cost per case averted (a reduction of 1% in the incidence of dengue fever). Deterministic sensitivity analyzes were performed to assess uncertainty. We assumed a cost-effectivness threshold of USD 70.000.

RESULTS

: We found that the eco-ssytemic intervention generates an additional costo of USD 45,342 and an incremental effectiveness of 0.5, rendering a cost-effectiveness ratio of USD 90,684, which is outside the proposed threshold for this economic evaluation. Therefore, the intervention plus the conventional program may not be a cost-effective strategy.

CONCLUSIONS

: Therefore, at current prices and with a willingness to pay For a reduction of 1% in the incidence of dengue fever, the eco-systemic intervention is not a cost-effective strategy in Colombia. However, result could change if the cost of technical service is 17% less than current cost
