OBJECTIVES : Estimate the annual cost of paraquat poisoning in Colombia

METHODS : A cost-disease study was made, using a decision tree model from the perspective of society, taking an approach based on prevalence. A probabilistic sensitivity analysis was made using the Monte Carlo technique with a simulation of a hypothetical cohort of 10,000 patients intoxicated by paraquat

RESULTS: An average cost per patient of US$ 2.642 (CI 95% 2.237-6.638 US$) was estimated for acute PQ poisoning. Taking into account the national report during 2017 of 344 cases to national surveillance system; the total cost of paraquat poisoning in Colombia amounts to US $ 892 336 per year

CONCLUSIONS: The average cost per patient intoxicated by paraquat exceeds that of various chronic diseases prevalent in our country. This reveals the impact not only clinical, but also economical, of this poisoning in our country, necessitating strategies that regulate commercialization to avoid premature deaths.
