RESUMEN
Chemical poisoning is considered a common medico-social problem that, in addition to causing extensive morbidity and mortality, dominates the valuable health care service resources. Therefore, this study was conducted to explore the extent and frequency of chemical poisoning events among adults in Qassim region as well as the most common poisoning agents involved. A retrospective method of data collection was used employing medical record review for chemical poisoning cases that occurred in Qassim region during the 8-year period from January 2008 to December 2015. Data were collected using a standardized, validated data collection sheet. The study revealed that there is no steady trend (either decreasing or increasing) of the number of poisoning cases through time. There is a statistically significant association between the type of poisoning agent and gender (χ2 = 14.3104, p < 0.05). Moreover, there is a statistically significant association between the type of poisoning agent and period in years (χ2 = 19.7565, p < 0.05). It can be concluded that poisoning cases are distributed, to some extent, evenly between males and females, with no pattern through time. Educational programs are needed to raise public awareness about poisoning, especially among women.
