"In this nationwide study of commercially insured adolescents, LTOT [Long Term Opioid Therapy] was relatively uncommon. The estimated incidence of LTOT receipt was 3.0 per 1000 adolescents within 3 years of filling an initial opioid prescription. Although adolescents with a wide range of preexisting mental health conditions and treatments were modestly more likely than adolescents without those conditions or treatments to receive an initial opioid, the former had substantially higher rates of subsequent transitioning to LTOT. Associations were strongest for OUD [Opioid Use Disorder], OUD medications, nonbenzodiazepine hypnotics, and other SUDs. The associations were stronger sooner after first opioid receipt for OUD, as well as for anxiety and sleep disorders and their treatments, suggesting that adolescents with these conditions and treatments were more likely to quickly transition into LTOT."
