Trends in Childhood Poison Exposures and Fatalities: A Retrospective Secondary Data Analysis of the 2009-2019 U.S. National Poison Data System Annual Reports.
Despite significant prevention efforts, childhood poison exposures remain a serious public health challenge in the United States. This study aimed to assess annual trends of pharmaceutical vs. non-pharmaceutical poison exposures in the US among children 0-19 years and compare the odds of death by childrens age group. Poison exposure and fatality data were retrospectively extracted from 2009 to 2019 National Poison Data System (NPDS) annual reports for children in all reported age groups. Overall, there was a significant reduction in the annual population-adjusted poison exposures in children (annual percentage change = -2.54%, 95% CI = -3.94% to -1.15%, p < 0.01), but not in poisoning-related fatalities. Children 0-5 had similar odds of dying from exposure to non-pharmaceuticals vs. pharmaceuticals. The odds of children 6-12 dying from non-pharmaceuticals vs. pharmaceuticals was 2.38 (95% CI = 1.58, 3.58), χ2 = 18.53, p < 0.001. In contrast, the odds of children 13-19 dying from pharmaceuticals vs. non-pharmaceuticals was 3.04 (95% CI = 2.51, 3.69), χ2 = 141.16, p < 0.001. Suicidal intent accounted for 40.63% of pharmaceutical deaths in children 6-12, as well as 48.66% of pharmaceutical and 31.15% of non-pharmaceutical deaths in children 13-19. While a significant decline in overall childhood poison exposures was reported, a decrease in poisoning-related fatalities was not observed. Children in different age groups had contrasting relative odds of death from pharmaceutical and non-pharmaceutical exposures. Among older children, a greater proportion of poisoning-related deaths was due to intentional suicide. These findings provide evidence of age-specific trends in childhood poison exposure risk and directions for future poison prevention efforts and behavioral health partnerships
Adverse events associated with dietary supplements: an observational study

METHODS: In 1998, 11 poison control centres in the USA recorded details of 2332 telephone calls about 1466 ingestions of dietary supplements, in 784 of which patients had symptoms. We used a multitiered review process (kappa 0.42) to select 489 cases for whom we were at least 50% certain that their negative events were associated with dietary supplements. We aimed to assess the effects of multiple ingredients and long-term use, and collated data for patterns of use and information resources. FINDINGS: A third of events were of greater than mild severity. We noted both new and previously reported associations that included myocardial infarction, liver failure, bleeding, seizures, and death. Increased symptom severity was associated with use of several ingredients, long-term use, and age. Paediatric exposures were more often unintentional than were adult ingestions, and treatment of disease was the reason for supplement use in at least 28% of reports. Most products and ingredients were not identified in the information database (Poisindex) used by poison control centres, and specific adverse events were reported variably among five additional sources. INTERPRETATION: Dietary supplements are associated with adverse events that include all levels of severity, organ systems, and age groups. Associations between adverse events and ingredients are difficult to verify if a product has more than one ingredient, and because of incomplete information systems. Research into hazards and risks of dietary supplements should be a priority
