Trends in opioid exposures among young children reported to United States poison centers from 2016 to 2023.

Introduction: The objective of this study was to update and expand on previous studies of opioid exposures among young children reported to America's Poison Centers®, and to describe how fentanyl and medications for opioid use disorder have contributed. Methods: This retrospective study investigated 34,632 reports of single-substance opioid exposure from 2016 to 2023 involving pediatric patients aged one month to six years old. Descriptive statistics, tests for data normality, and significance testing were performed where applicable. Results: Of 34,632 reported exposures, 96.7% were unintentional. The median age of exposure was 2.0 years (IQR 1.33-3.0 years). Reported exposures decreased by 57.5% over the study period (r = −0.96; P <0.001). However, there was a 300% absolute increase in deaths and major effects (r = 0.96; P <0.001). Exposures resulting in minor, no effect, not followed, or unable to follow decreased 66.2% (r = −0.99; P <0.001). Buprenorphine was most frequently involved, comprising 23.4% of reported exposures. Buprenorphine (OR 1.93; P <0.001) and methadone (OR 14.98; P <0.001) were associated with an increased risk of severe effects when compared to other prescription drugs (OR: 1). There was an absolute increase of 512% over time in reports of heroin, fentanyl, synthetic non-pharmaceutical opioids (r = 0.92; P <0.001), which were also associated with severe effects (OR 20.1; P <0.001). Discussion: Pediatric opioid exposures have previously been reported to be relatively stable. It is likely the 57.5% reduction is exaggerated due to underreporting from health care providers. However, decreases in exposures are presumed to be balanced throughout the dataset and, therefore, without differential impact on other points of analysis. Our study highlights the continued need for enhanced poisoning prevention strategies. Conclusions: The relative severity of poisonings reported to poison centers worsened over the study period. The opioids implicated have shifted away from hydrocodone, oxycodone, and tramadol, and towards fentanyl and buprenorphine. [ABSTRACT FROM AUTHOR]
