Objective: This retrospective study describes the role of behavioral health in an addiction medicine program integrated in a primary care clinic, and evaluates retention, substance use, and mental health symptoms for patients in a rural underserved community. Method: Data were abstracted from records of patients referred for buprenorphine treatment of opioid use disorder (N ϭ 101; 45% female, 23% Native Hawaiian or Pacific Islander, M age ϭ 42.5, SD ϭ 12.75). Among patients prescribed buprenorphine (n ϭ 61), most had comorbid substance-related diagnoses (72% with tobacco use, 75% with at least one other substance use disorder) and non-substance-related mental health diagnoses (77%), most commonly depression and anxiety. Integrated sessions with a behavioral health provider and a buprenorphinewaivered prescriber occurred weekly to monthly. Participants completed depression and anxiety questionnaires (Patient Health Questionnaire-9 and Generalized Anxiety Disorder Scale-7) and provided urine samples at each visit. Results: Most patients (72%) were retained for at least 3 months, with early dropout associated with higher initial depression and anxiety scores. Inconsistent urine drug tests (i.e., those positive for illicit/nonprescribed substances) were significantly more common at treatment initiation (74%) than during the most recent visit (43%, p Ͻ .001), and were associated with baseline substance and other mental health factors, as well as shorter treatment duration. Generalized estimating equations models suggested time-based improvements in depression and anxiety symptoms, especially for patients retained for at least 3 months. Conclusions: Integrating wraparound addiction treatment within a rural primary care setting is feasible and associated with improved mental health and retention outcomes.
What is the public health significance of this article?Addiction medicine services integrated in primary care health care centers can help make treatment for opioid use disorders and comorbid substance use and other mental health conditions accessible for rural underserved populations. The greater improvements associated with remaining in treatment suggest opportunities for multidisciplinary teams to identify and reduce psychological, physical, and psychosocial barriers to remaining in treatment.
