IntroductionPoisonings are a worldwide preventable public health problem that affects the general population.ObjectiveTo epidemiologically characterize BZ and AD poisonings registered in Chile between 2002 and 2019.MethodsAn observational retrospective study of poisonings registered in the medical outcome report system of the Chilean Ministry of Health was conducted. The World Health Organization International Classification of Disease codes T42.2, T43.0 and T43.2 were included.Results22,807 poisonings associated with BZ or AD were identified, representing 0.08% of all hospitalizations. Poisoning rates distribution were established at regional and national level. There were 9.8% of accidental events, 63.7% of intentional events, and 26.5% of undetermined cases. The highest accidental and intentional poisoning rates were estimated at the ages of 0 to 4 and 15 to 19 years old respectively. Poisoned patients remained hospitalized on average for 3.4 days. 0.3% of cases were related to death of patients.ConclusionsPoisoning events were characterized according to the studied variables. National poisoning rates decreased over the years with prevalence of those intentional events linked to women. Efforts should be made in creating poisoning prevention campaigns focused on age-based groups in the general population.
