N2  - In recent years, there has been an increase in poisoning-related emergency department (ED) visits. This study examines trends in ED resource utilization for poisoning-related visits over time. A retrospective review of data from the National Hospital Ambulatory Medical Care Survey, 2003-2011, was conducted. All ED visits with a reason for visit or ICD-9 code related to poisoning were included. We examined the number of ED visits and resources used including diagnostic studies and procedures performed, medications provided, admission rates, and length of stay. The proportion of visits involving resource use was tabulated and trends analyzed using survey-weighted logistic regression, grouping into 2-year periods to ensure adequate sample size. Of an estimated 843 million ED visits between 2003 and 2011, 8 million (0.9 %) were related to poisoning. Visits increased from 1.8 million (0.8 %) visits in 2003-2004 to 2.9 million (1.1 %) visits in 2010-2011, p = 0.001. Use of laboratory studies, EKGs, plain radiographs, and procedures remained stable across the study period. CT use was more than doubled, increasing from 5.2 to 13.7 % of visits, p = 0.001. ED length of stay increased by 35.5 % from 254 to 344 min, p = 0.001. Admission rates increased by 45.3 %, from 15.0 to 21.8 %, p = 0.046. Over the entire study period, 52.0 % of poisoned patients arrived via ambulance, and 3.0 % of patients had been discharged from the hospital within the previous 7 days. Poisoning-related ED visits increased over the 8-year study period; poisonings are resource-intensive visits and require increasingly longer lengths of ED stay or hospital admission
