Medications for Opioid Use Disorder Among Transition Age Youth Compared to Adults 26 or Older in Rural Settings

Objective Transition Age Youth (TAY), aged 18-25 years, face barriers to medication treatment for opioid use disorder (MOUD) resulting in lower retention. We evaluated OUD prevalence and MOUD receipt comparing TAY to adults aged 26 or older residing in rural settings. Method Electronic Health Records (October 2019 - January 2021) for 36,762 patients across six primary care clinics involved in a large feasibility trial in US rural communities were analyzed. All clinics implemented a standardized intervention. Mixed effects logistic/linear regression estimated odds of OUD diagnosis among all patients; and among those with OUD, the odds of receiving MOUD and days prescribed MOUD during the 15-month study period, comparing age categories (TAY=18-25 years vs. adults 26 or older). Covariates included gender, race, ethnicity, mental health comorbidities, and insurance status. Results OUD prevalence was 2.82% among TAY (n=3,122) and 3.24% among adults aged 26 or older (n=33,208). After adjusting for covariates and clustering, TAY had significantly lower odds of OUD diagnosis compared to adults 26 years or older (OR=0.58, 95% CI 0.45 to 0.73). There were no significant differences in MOUD receipt between age groups. Compared to adults 26 or older, TAY with OUD had significantly fewer MOUD days during the study, -43.81 days (-76.85 to -10.77). Conclusion While no differences were observed in MOUD prescription receipt between TAY and adults 26 or older, TAY with OUD had fewer total days prescribed MOUD indicating lower retention. Further research generalizable to rural communities is needed to assess retention among rural TAY with OUD.
