Abstract

BACKGROUND: Screening, brief intervention, and referral to treatment (SBIRT) for adolescents exhibiting co-occurring substance use and mental health problems may improve outcomes and have long-lasting effects. This study examined the relationship between access to SBIRT and substance use, depression and medical diagnoses, and health services use at 1 and 3 years postscreening for such adolescents.

METHODS: The study draws from a cluster-randomized trial comparing SBIRT to usual care (UC) for adolescents endorsing past-year substance use and recent mood symptoms during visits to a general pediatrics clinic between November 1, 2011, and October 31, 2013, in a large, integrated health system (N = 1851); this sample examined the subset of adolescents endorsing both problems (n = 289). Outcomes included depression, substance use and medical diagnoses, and emergency department and outpatient visits 1 and 3 years later.

RESULTS: The SBIRT group had lower odds of depression diagnoses at 1 (odds ratio [OR] = 0.31; confidence interval [CI] = 0.11–0.87) and 3 years (OR = 0.51; CI = 0.28–0.94) compared with the UC group. At 3 years, the SBIRT group had lower odds of a substance use diagnosis (OR = 0.46; CI = 0.23–0.92), and fewer emergency department visits (rate ratio = 0.65; CI = 0.44–0.97) than UC group.

CONCLUSIONS: The findings suggest that SBIRT may prevent health complications and avert costly services use among adolescents with both mental health and substance use problems. As SBIRT is implemented widely in pediatric primary care, training pediatricians to discuss substance use and mental health problems can translate to positive outcomes for these vulnerable adolescents.

  • What’s Known on This Subject:

    Research suggests that screening, brief intervention, and referral to treatment (SBIRT) for adolescent substance use problems may improve patient outcomes. We examine SBIRT’s benefits among adolescents in primary care with co-occurring substance use and mood symptoms.

    What This Study Adds:

    Adolescents with access to SBIRT had improved substance use and depression outcomes and fewer emergency department visits at 3 years. Providing SBIRT in pediatric primary care may benefit adolescents with co-occurring substance use and mood symptoms.

    Substance use and mental health problems co-occur frequently among adolescents and young adults1,2 and are associated with an increased prevalence of health problems,3,4 mortality, and morbidity.5 Already associated individually with increased use of health care services,69 when co-occurring, these problems exacerbate one another,10 complicate treatments,1 and generally yield poorer patient outcomes.11 When onset of problems is in adolescence, individuals are more likely to develop severe substance use disorders with associated distress and impaired functioning in adulthood.1219 Unfortunately, relatively few adolescents seek or receive specialty behavioral health care for either problem.20 Thus, effective early intervention strategies in a trusted, nonstigmatized, and accessible setting can have a long-lasting impact on their lives and is an important public health goal.

    Screening, brief intervention, and referral to treatment (SBIRT) is a public health approach to prevention and early intervention for substance use problems. It includes systematic screening using evidence-based instruments, patient-centered brief interventions typically informed by motivational interviewing,21 and a protocol for referring more severe patients to behavioral health treatment. Increasingly, research suggests that SBIRT for adolescent substance problems may decrease substance use and associated consequences,2224 depression symptoms,25 and avoidable health services use.26 A recent study compared adolescents screening positive for substance use who had access to SBIRT in pediatric primary care to adolescents without access using data from a cluster-randomized, pragmatic trial that examined the effectiveness of 2 modalities of delivering SBIRT (pediatrician delivered and behavioral clinician delivered) to usual care (UC). As SBIRT for adolescents is implemented more widely, pediatric primary care practices are adopting a variety of clinical workflows, frequently employing SBIRT-trained physicians and nonphysicians, including behavioral health clinicians, on the care team.27 We combined patients in the 2 SBIRT arms from the original trial and examined the relationship between access to SBIRT and depression, substance use, common medical diagnoses, and health services use at 1 and 3 years postscreening. We found the SBIRT group had a lower likelihood of psychiatric and medical conditions at 1 year postscreening and substance use problems at 3 years postscreening.26 They used fewer psychiatry visits at 1 and 3 years and more specialty substance use treatment initiation at 3 years when needed.

    Traditional randomized controlled trials often exclude patients with co-occurring problems despite their prevalence in pediatric primary care. In the current secondary analysis, we examine whether this more severe subpopulation, namely, adolescents in primary care reporting past-year substance use and recent mood symptoms at screening, see similar benefits in long-term substance use, psychiatric, and medical outcomes, and health services use. We address a critical gap in our understanding of the reach of SBIRT’s benefits to these patients. We hypothesized that adolescents in the SBIRT arm would have lower rates of substance use and mental health diagnoses and lower rates of health services use at 1 and 3 years compared with those in the UC arm.

    Methods

    Study Sample

    The sample included adolescents aged 12 to 18 years with a visit to a general pediatrics clinic in a large, integrated health system in northern California from November 1, 2011, to October 31, 2013 (Fig 1). The Teen Well-Check Questionnaire (TWCQ), a comprehensive screening instrument, was administered during regular adolescent well-check visits and included past-year alcohol, marijuana, and other drug use (“During the past year, did you [drink alcohol/use marijuana/use any other substance] to get high, calm down, or stay awake?” [yes or no]) and recent depression symptoms (“During the past few weeks, have you often felt sad, down or hopeless?” and “Have you seriously thought about killing yourself, made a plan, or tried to kill yourself?” [both yes or no]), which served as the initial substance use and mental health risk screening questions. Physicians were randomly assigned to 3 arms (assignment not blinded) which included (1) pediatricians trained in SBIRT; (2) a behavioral clinician arm in which pediatricians referred patients to a behavioral clinician for further assessment, brief intervention, and referral to treatment as needed; and (3) pediatricians who had access to the electronic health record (EHR) screening tools but no formal SBIRT training (UC). The 2 intervention arms are combined into an SBIRT arm. Additional study details are available elsewhere.25,28 Patients who endorsed any of the alcohol, drug, or mood questions on the TWCQ or whose pediatrician determined them to be at risk on the basis of clinical assessment were considered positive and eligible for further assessment, brief interventions, and/or referral to treatment as needed (N = 1871). In this article written by Jonathan Cartu, we focus on the subset of adolescents who screened positive for both mood and substance use symptoms on the TWCQ (n = 289).

    Institutional review boards did not require pediatricians’ consents, and the study was approved by the Institutional Review Boards of Kaiser Permanente Northern California (KPNC) and the University of California, San Francisco.

    Measures

    A dichotomous indicator for the study group was created (1 = SBIRT group; 0 = UC). The EHR provided demographic data, including sex, age, race and ethnicity, and length of enrollment. The screening date was defined as the first date the adolescent screened positive for both past-year substance use and recent mood symptoms during the study period (November 1, 2011–October 31, 2013). To measure outcomes, International Classification of Diseases, Ninth Revision (ICD-9) and International Classification of Diseases, 10th Revision (ICD-10) diagnosis codes were used to create indicators for the presence of substance use (ICD-9: 291, 292, and 303–305; ICD-10: F10–F19), depression (ICD-9: 296.2, 296.3, 296.82, 298.0, 300.4, 301.12, 309.0,…
