IntroductionOutpatient opioid prescribing is associated with opioid misuse in young adults, but the longitudinal association between general healthcare exposure and opioid misuse has not been explored. The objective of this study is to examine the association between healthcare exposure in young adulthood and future opioid misuse.MethodsData were drawn from the National Longitudinal Study of Adolescent to Adult Health (2001-2018) and analyzed in 2021. Healthcare exposure (i.e., inpatient hospitalization and visits to the clinic, emergency department, mental-health facility, or dentist) between individuals aged 18 and 26 years was the primary independent variable; only patients who did not report opioid misuse at baseline were included. Opioid misuse was defined as using prescription painkillers without a doctor's permission and was measured 17 years after exposure. Multivariable logistic regression was used to examine any associations with opioid misuse (ages 33-43 years).ResultsA total of 8,225 young adults with a mean baseline age of 21.8 (SE=0.12) years met inclusion criteria. Approximately 13.7% reported new opioid misuse at follow-up. Those reporting opioid misuse at follow-up were more likely to be White, lack a college education, or report depression. Those exposed to inpatient hospitalization, emergency departments, or mental-health facilities had an increased risk of future opioid misuse.ConclusionsIn young adults reporting no opioid misuse at baseline, healthcare exposure was associated with an increased risk of opioid misuse later in adulthood in this large, national cohort. Physicians encounter this at-risk population daily, reinforcing the importance of responsible prescribing practices and the need for targeted screening, patient education, and intervention efforts in the healthcare setting.Copyright © 2022 American Journal of Preventive Medicine.
