OBJECTIVE

To examine changes in acute health care encounters, and to identify risk factors associated with substance use among the pediatric population before, during, and after the COVID-19 pandemic.

METHOD

We conducted an interrupted time series analysis to assess changes in acute health care encounters related to substance use from 2017 to 2023 among a national sample of youth 6 to 17 years of age. Based on sociodemographic variables, logistic regression analyses were used to predict substance use encounters. We examined their interactions with the COVID-19 era to highlight differences in these acute encounters before, during, and after the pandemic.

RESULTS

Records for more than 20 million acute health care encounters were examined among the pediatric population from 2017 through 2023. Of these records, 219,267 had substance use diagnoses. During the COVID-19 era, the proportion of encounters associated with substance use increased, and then post pandemic declined to pre-pandemic levels. The most common substances attributed to acute health care encounters were marijuana (n = 141,273) and alcohol (n = 45,147). Health care encounters attributed to substance use were more common in older youth (13-17 years of age), male youth, and youth who were American Indian or Alaska Native. Additional disparities were associated with certain substances, indicating the need for tailored public health and clinical interventions among these populations.

CONCLUSION

Although overall health care encounters dropped during the pandemic, the proportion of visits attributed to substance use increased significantly during that time. Of note, encounters attributed to marijuana use have remained elevated among youth. Unique risk factors may exist for health care encounters based on substance, warranting the need for additional research on these disparities.
