0408 Insomnia, hypersomnia, and depression in buprenorphine treated opioid use disorder subjects

Abstract

Abstract Introduction Sleep disturbances and depression are highly prevalent in Opioid use disorder subjects treated with buprenorphine. However, the association between sleep disturbances such as insomnia/hypersomnia and depression in the above patient population is not known. The aim of the study is to examine the association between sleep disturbances including insomnia and hypersomnia with depressive disorders in buprenorphine treated opioid use disorder (OUDB) subjects. Methods We studied 92 OUDB (38±11.2y, 49% female, 9% minority) at the Recovery, Advocacy, Empowerment and Service program (RASE) and Internal Medicine clinics of Wellspan (York, PA). Subjects completed the Patient Health Questionaire-9 (PHQ-9), Insomnia Severity Index (ISI), Epworth sleepiness scale (ESS), and opioid craving scale (OCS). Depression was defined as a PHQ 9 score ≥ 10, insomnia with an ISI score of >15 and excessive daytime sleepiness (EDS) with an ESS score of >10. Binary logistic regression analysis evaluated the likelihood of OUDB subjects having depression in relation to insomnia, excessive daytime sleepiness (EDS), opioid craving, duration of opioid use, duration since last use of any illegal substance, number of rehabilitation treatments and buprenorphine dosage. Results No differences between in OUDB subjects with (n=47) and without (n=34) depression were observed in age, duration of opioid dependence, duration of buprenorphine treatment, number of rehabilitation treatments or time since last use of any illegal substance. Subjects with depression had significantly higher ISI (18.2±4.2 verus11.8±6.6, p< 0.01), ESS (11.2±4.7 versus 8.2±4.1, p< 0.01 ) scores and a trend towards higher OCS score (3.2±4.1 verus1.9±2.2, p=0.056) as compared to those without depression. The odds of depression associated with Insomnia and EDS were 8.5 (95%CI=2.3-31.2) and 4.4 (95%CI=1.1-17) times respectively in this patient population. Conclusion Insomnia and hypersomnia are highly associated with depression in buprenorphine treated OUDBs patients. Insomnia and hypersomnia needs to be evaluated early and receive targeted treatment during early abstinence in order to prevent relapse in this patient population.
