A conceptual model to facilitate transitions from primary care to specialty substance use disorder care: a review of the literature

HIV status and substance use disorder treatment need and utilization among adults in the United States, 2015-2019: Implications for healthcare service provision and integration

INTRODUCTION

Substance use disorders (SUD) are associated with HIV acquisition and care disruptions. Most research focuses on clinical samples; however, we used a nationally representative, community-based sample to estimate SUD treatment need and utilization by HIV status.

METHODS

We included participants from the 2015-2019 National Survey on Drug Use and Health aged 18 and older who met past-year DSM-IV SUD criteria (n = 22,166). Participants self-reported whether a healthcare professional ever told them they had HIV or AIDS [i.e., people with HIV (PWH), non-PWH, HIV status unknown]. Outcomes included past-year: 1) any SUD treatment use; 2) any specialty SUD treatment use; and 3) perceived SUD treatment need. Survey weighted multivariable logistic regression models estimated the likelihood of each outcome by HIV status, adjusting for age, sex, race/ethnicity, education, survey year, health insurance status, and household income.

RESULTS

Overall, 0.5 % were PWH and 0.8 % had an HIV unknown status. Any past-year SUD treatment utilization was low across all groups (10.3 % non-PWH, 24.2 % PWH, and 17.3 % HIV status unknown respondents). Specialty SUD treatment utilization was reported by 7.2 % of non-PWH, 17.8 % PWH, and 10.9 % HIV status unknown respondents. Perceived treatment need was reported by 4.9 % of non-PWH, 12.4 % of PWH, and 3.7 % of HIV status unknown respondents. In adjusted models, PWH were more likely than non-PWH to report any past-year SUD treatment utilization (aOR = 2.06; 95 % CI = 1.08-3.94) or past-year specialty SUD treatment utilization (aOR = 2.07; 95 % CI = 1.07-4.01). Among those with a drug use disorder other than cannabis, respondents with HIV-unknown status were less likely than HIV-negative individuals to report past-year perceived treatment need (aOR = 0.39; 95 % CI = 0.20-0.77).

CONCLUSIONS

Despite high SUD treatment need among PWH, more than three quarters of PWH with SUD reported no past-year treatment. Compared to non-PWH, PWH had higher treatment utilization and higher specialty treatment utilization, but SUD treatment was low across all groups. As SUD is associated with adverse HIV outcomes, our findings highlight the need for the integration of SUD treatment with HIV testing and care. Increasing access to SUD treatment could help reduce negative SUD-related outcomes along the HIV care continuum.

Standard Versus Family-Based Screening, Brief Intervention, and Referral to Treatment for Adolescent Substance Use in Primary Care: Protocol for a Multisite Randomized Effectiveness Trial

BACKGROUND

Screening, brief intervention, and referral to treatment for adolescents (SBIRT-A) is widely recommended to promote detection and early intervention for alcohol and other drug (AOD) use in pediatric primary care. Existing SBIRT-A procedures rely almost exclusively on adolescents alone, despite the recognition of caregivers as critical protective factors in adolescent development and AOD use. Moreover, controlled SBIRT-A studies conducted in primary care have yielded inconsistent findings about implementation feasibility and effects on AOD outcomes and overall developmental functioning. There is urgent need to investigate the value of systematically incorporating caregivers in SBIRT-A procedures.

OBJECTIVE

This randomized effectiveness trial will advance research and scope on SBIRT-A in primary care by conducting a head-to-head test of 2 conceptually grounded, evidence-informed approaches: a standard adolescent-only approach (SBIRT-A-Standard) versus a more expansive family-based approach (SBIRT-A-Family). The SBIRT-A-Family approach enhances the procedures of the SBIRT-A-Standard approach by screening for AOD risk with both adolescents and caregivers; leveraging multidomain, multireporter AOD risk and protection data to inform case identification and risk categorization; and directly involving caregivers in brief intervention and referral to treatment activities.

METHODS

The study will include 2300 adolescents (aged 12-17 y) and their caregivers attending 1 of 3 hospital-affiliated pediatric settings serving diverse patient populations in major urban areas. Study recruitment, screening, randomization, and all SBIRT-A activities will occur during a single pediatric visit. SBIRT-A procedures will be delivered digitally on handheld tablets using patient-facing and provider-facing programming. Primary outcomes (AOD use, co-occurring behavior problems, and parent-adolescent communication about AOD use) and secondary outcomes (adolescent quality of life, adolescent risk factors, and therapy attendance) will be assessed at screening and initial assessment and 3-, 6-, 9-, and 12-month follow-ups. The study is well powered to conduct all planned main and moderator (age, sex, race, ethnicity, and youth AOD risk status) analyses.

RESULTS

This study will be conducted over a 5-year period. Provider training was initiated in year 1 (December 2023). Participant recruitment and follow-up data collection began in year 2 (March 2024). We expect the results from this study to be published in early 2027.

CONCLUSIONS

SBIRT-A is widely endorsed but currently underused in pediatric primary care settings, and questions remain about optimal approaches and overall effectiveness. In particular, referral to treatment procedures in primary care remains virtually untested among youth. In addition, whereas research strongly supports involving families in interventions for adolescent AOD, SBIRT-A effectiveness trial testing approaches that actively engage family members in primary care are absent. This trial is designed to help fill these research gaps to inform the critical health decision of whether and how to include caregivers in SBIRT-A activities conducted in pediatric primary care.

Hazardous Drinking Interventions Delivered During Medical-Surgical Care: Patient and Provider Views

Addressing hazardous drinking during medical-surgical care improves patients' health. This formative evaluation examined patients' consideration of options to change drinking and engage in treatment. It explored whether interventions such as "DO-MoST" overcome treatment barriers. We interviewed 20 medical-surgical patients with hazardous drinking in a trial of DO-MoST, and 16 providers. Analyses used a directed content approach. Patients were receptive to and comfortable discussing drinking during medical-surgical care. Interventions like DO-MoST (patient-centered, motivational approach to shared decision making) addressed some treatment barriers. Patients and providers viewed such interventions as helpful by building a relationship with a psychologist who facilitated self-awareness of drinking behaviors, and discussing connections between alcohol- and physical health-related problems and potential strategies to address drinking. However, both groups expressed concerns about individual and system-level barriers to long-term change. Interventions like DO-MoST bridge the gap between the patient's medical treatment episode and transition to other health care settings. TRIAL REGISTRATION: The study is registered on ClinicalTrials.gov (ID: NCT03258632).

Connect To Care (C2C): protocol for two-site randomized controlled pilot trial to improve outcomes for patients with hazardous drinking and PTSD and/or depression symptoms

BACKGROUND

In studies of the general population and of military veterans, many primary care patients with hazardous drinking and PTSD and/or depression (abbreviated here as HD +) do not initiate or engage with alcohol-related care. To address this gap in care, we identified and will pilot test a promising evidence-based intervention, Connect To Care (C2C). C2C is a strengths-based approach, delivered by a Care Coach by telephone and/or video, with four components: (1) identifying and leveraging patient strengths to facilitate care initiation, (2) collaborative decision-making around a menu of care options, (3) identifying and resolving barriers to care, and (4) monitoring and facilitating progress toward care initiation by, for example, checking on barriers, identifying solutions, and revisiting care options.

METHODS/DESIGN

Aim 1 will involve adapting C2C for use in Veterans Affairs' (VA) primary care. We will use an iterative process that includes focus groups and semi-structured interviews with key stakeholders (patients, primary care providers, and VA national policy leaders). In Aim 2, we will conduct a two-site, pilot randomized controlled trial to determine the feasibility of conducting a larger scale trial to test C2C's effectiveness, ascertain the acceptability of C2C among primary care patients with HD + , and explore the efficacy of C2C to improve veteran patients' initiation of and engagement in alcohol care, and their alcohol and mental health (PTSD, depression) outcomes, at 3-month follow-up. We will explore explanatory mechanisms by which C2C is effective.

DISCUSSION

Study findings are likely to have implications for clinical practice to enhance current approaches to linking patients with HD + to alcohol care by applying a practical intervention such as C2C. The results may improve treatment outcomes for people with HD + by drawing on patients' strengths to problem-solve barriers to care following a process of shared decision-making with a coach. In addition to possibly accelerating the translation of C2C into practice, study findings will also support additional research in terms of a planned effectiveness-implementation hybrid trial, adding to this study's potential for high impact.

Effectiveness of a pharmacist-delivered primary care telemedicine intervention to increase access to pharmacotherapy and specialty treatment for alcohol use problems: Protocol for the alcohol telemedicine consult cluster-randomized pragmatic trial

BACKGROUND

Alcohol use problems are associated with serious medical, mental health and socio-economic consequences. Yet even when patients are identified in healthcare settings, most do not receive treatment, and use of pharmacotherapy is rare. This study will test the effectiveness of the Alcohol Telemedicine Consult (ATC) Service, a novel, personalized telehealth intervention approach for primary care patients with alcohol use problems.

METHODS

This cluster-randomized pragmatic trial, supplemented by qualitative interviews, will include adults with a primary care visit between 9/10/21-3/10/23 from 16 primary care clinics at two large urban medical centers within Kaiser Permanente Northern California, a large, integrated healthcare system. Clinics are randomized to the ATC Service (intervention), including alcohol pharmacotherapy and SBIRT (screening, MI (Motivational Interviewing)-based brief intervention and referral to addiction treatment) delivered by clinical pharmacists, or the Usual Care (UC) arm that provides systematic alcohol SBIRT. Primary outcomes include a comparison of the ATC and UC arms on 1) implementation outcomes (alcohol pharmacotherapy prescription rates, specialty addiction treatment referrals); and 2) patient outcomes (medication fills, addiction treatment initiation, alcohol use, healthcare services utilization) over 1.5 years. A general modeling approach will consider clustering of patients/providers, and a random effects model will account for intra-class correlations across patients within providers and across clinics. Qualitative interviews with providers will examine barriers and facilitators to implementation.

DISCUSSION

The ATC study examines the effectiveness of a pharmacist-provided telehealth intervention that combines pharmacotherapy and MI-based consultation. If effective, the ATC study could affect treatment models across the spectrum of alcohol use problems.

Primary care provider expectations of addiction services and patients in Spain

BACKGROUND

Primary care (PC) is crucial in the care of substance use disorder (SUD) patients. However, the relationship between PC and addiction settings is complex and collaboration issues stand out. Available evidence suggests that integration of SUD and PC services can improve physical and mental health of SUD patients and reduce health expenses.

OBJECTIVE

To explore the experiences, views and attitudes of PC professionals towards the interaction between PC and SUD services.

METHODS

Twenty-seven GPs took part in three focus groups. The focus group sessions were audio-taped, transcribed verbatim and analysed using reflexive thematic analysis. Recurrent themes were identified.

RESULTS

Four main themes were devised: (1) Differences and specificities of SUD patients, (2) Interaction between providers of PC and addiction services, (3) Patient management (4) Addiction stigma. These main themes reflect the consideration that SUD patients are a specific group with specific care needs that yield specific challenges to GPs themselves. Improved training, availability of a shared medical record system, increased feedback between GP and addiction specialists and the efficiency of the circuit are to be considered the main priority for the majority of the participants.

CONCLUSIONS

An efficient and effective referral circuit, with increased feedback and shared medical records is considered key to GPs. Its implementation should keep in mind the specific features of both SUD patients and GPs.

Patient Perspectives on Detox: Practical and Personal Considerations through a Lens of Patient-Centered Care

Inpatient detoxification is often required before a client can move on to additional substance abuse treatment services. Although often short-term, time spent in inpatient detoxification tends to have long-lasting effects on the recovery process. This qualitative study focuses on one treatment facility in Tampa, Florida that offers a range of recovery services, including inpatient detox and outpatient treatment. Focus groups (N = 70 participants) captured client perceptions of direct clinical care operations, access to resources, and relationships with direct care staff within the inpatient detox program. Perceptions were then assessed using a thematic analysis approach with attention to the literature on person-centered care best practices, behavior change, and patient engagement theories to better understand how facility practices affect treatment engagement and retention. Findings elucidated several practical facilitators and barriers to recovery such as facility resources, services offered, transition to aftercare, and sustainability of treatment. Findings also illuminated several personal facilitators and barriers including patient-staff interactions, personal motivation, and family and community support. The resulting recommendations for practice and research are discussed.

Health Services Use Among Jailed Women with Alcohol Use Disorders

Correctional facilities now house unprecedented numbers of women with complex treatment needs. This investigation applied the Behavioral Model for Vulnerable Populations to study 168 jailed women with alcohol use disorders. It described the sample's predisposing (age, race, victimization), enabling (health insurance), and need (self-reported medical, substance use, and mental health problems) factors and examined associations of these factors with pre-incarceration services utilization. Most participants had clinically significant levels of depression and PTSD symptoms, most took psychiatric medications, and most had been victimized. Participants reported considerable health services utilization. Younger, Black, and uninsured women utilized fewer medical and mental health services. Drug use was associated with less use of medical services, but more use of alcohol and drug services. High rates of health services use support the need for integrated, ongoing care for substance-using women before, during, and after incarceration.

Linking Individuals with Substance Use Disorders (SUDs) in Primary Care to SUD Treatment: the Recovery Management Checkups-Primary Care (RMC-PC) Pilot Study

Linking individuals in primary care settings with substance use disorders (SUDs) to SUD treatment has proven to be challenging, despite the widespread use of Screening, Brief Intervention, and Referral to Treatment (SBIRT). This paper reports findings from a pilot study that examined the efficacy of the Recovery Management Checkups intervention adapted for primary care settings (RMC-PC), for assertively linking and engaging patients from Federally Qualified Health Centers into SUD treatment. Findings showed that patients in the RMC-PC (n=92) had significantly higher rates of SUD treatment entry and received more days of SUD treatment compared with those who receive the usual SBIRT referral (n=50). Receipt of RMC-PC had both direct and indirect effects, partially mediated through days of SUD treatment, on reducing days of drug use at 6 months post intake. RMC-PC is a promising intervention to address the need for more assertive methods for linking patients in primary care to SUD treatment.

Patient-Reported Offers of Alcohol Treatment for Primary Care Patients at High-Risk for an Alcohol Use Disorder

BACKGROUND

This study assessed patient-reported alcohol treatment offers by health care providers following routine annual screening for alcohol use in primary care.

METHODS

A telephone interview within 30 days of the annual screen assessed demographics, alcohol and other drug use, mental health symptoms, and offers of formal treatment for alcohol by a Veterans Affairs health care provider. We included male patients (n = 349) at high risk for an alcohol use disorder (AUD) who had not received alcohol treatment in the past 3 months. We assessed self-reported receipt of any offers of formal treatment for alcohol use and associations of offers of formal treatment for alcohol with demographic and clinical variables.

RESULTS

A total of 145 patients (41.5%) reported an offer of at least 1 type of formal treatment for alcohol use. More severe alcohol misuse (odds ratio, 1.07; 95% confidence interval, 1.03-1.11) and younger age (odds ratio, 0.97, 95% confidence interval, 0.95-0.99) were associated with reporting an offer of formal treatment.

CONCLUSION

Most primary care patients at high risk for an AUD were not offered treatment following annual screening. Our results highlight the importance of training primary care providers in what constitutes appropriate medical treatment for this population and the most effective ways of offering treatment.

Transitioning From Detoxification to Substance Use Disorder Treatment: Facilitators and Barriers

Although successful transitions from detoxification to substance use disorder treatment are associated with improved outcomes, many detoxification patients do not initiate treatment. This qualitative study informs detoxification and addiction treatment providers, and health systems, about how to improve detoxification to treatment transitions, by reporting detoxification providers' views of transition facilitators and barriers. The sample consisted of 30 providers from 30 Veterans Health Administration detoxification programs. Themes regarding transition facilitators and barriers emerged at the patient, program (detoxification programs, and addiction programs), and system levels. Detoxification program-level practices of discharge planning, patient education, and rapport building were reported as facilitating the transition to treatment. Six themes captured transition facilitators within addiction treatment programs: the provision of evidence-based practices, patient-centered care, care coordination, aftercare, convenience, and a well-trained and professional staff. This study expands previous literature on detoxification and addiction treatment by systematically and qualitatively examining factors that promote and hinder treatment initiation after inpatient and outpatient detoxification, from a provider perspective, in an era of health care reform and expanded substance use disorder treatment.

Screening and brief intervention for unhealthy substance use in patients with chronic medical conditions: a systematic review

AIMS AND OBJECTIVES

This systematic review describes studies evaluating screening tools and brief interventions for addressing unhealthy substance use in primary care patients with hypertension, diabetes or depression.

BACKGROUND

Primary care is the main entry point to the health care system for most patients with comorbid unhealthy substance use and chronic medical conditions. Although of great public health importance, systematic reviews of screening tools and brief interventions for unhealthy substance use in this population that are also feasible for use in primary care have not been conducted.

DESIGN

Systematic review.

METHODS

We systematically review the research literature on evidence-based tools for screening for unhealthy substance use in primary care patients with depression, diabetes and hypertension, and utilising brief interventions with this population.

RESULTS

Despite recommendations to screen for and intervene with unhealthy substance use in primary care patients with chronic medical conditions, the review found little indication of routine use of these practices. Limited evidence suggested the Alcohol Use Disorders Identification Test and Alcohol Use Disorders Identification Test-C screeners had adequate psychometric characteristics in patients with the selected chronic medical conditions. Screening scores indicating more severe alcohol use were associated with health-risk behaviours and poorer health outcomes, adding to the potential usefulness of screening for unhealthy alcohol use in this population.

CONCLUSIONS

Studies support brief interventions' effectiveness with patients treated for hypertension or depression who hazardously use alcohol or cannabis, for both substance use and chronic medical condition outcomes.

RELEVANCE TO CLINICAL PRACTICE

Although small, the international evidence base suggests that screening with the Alcohol Use Disorders Identification Test or Alcohol Use Disorders Identification Test-C and brief interventions for primary care patients with chronic medical conditions, delivered by nurses or other providers, are effective for identifying unhealthy substance use and associated with healthy behaviours and improved outcomes. Lacking are studies screening for illicit drug use, and using single-item screening tools, which could be especially helpful for frontline primary care providers including nurses.

Receptivity to alcohol-related care among U.S. women Veterans with alcohol misuse

Previous research indicates women Veterans have a potentially large, unmet need for alcohol-related care but are under-represented in treatment settings. The purpose of this study was to identify factors associated with women Veterans' receptivity to a recommendation for alcohol-related care when they present to Veterans Affairs (VA) primary care with alcohol misuse. Semi-structured interviews were conducted from 2012-2013 with 30 women Veterans at two VA facilities who screened positive for alcohol misuse during a primary care visit and discussed their alcohol use with their primary-care provider. Qualitative analyses identified 9 themes women used to describe what affected their receptivity to a recommendation for alcohol-related care (i.e., VA specialty substance use disorder services). The most common themes positively associated with women's receptivity included self-appraisal of their drinking behavior as more severe, the provider's presentation of treatment options, availability of gender-specific services, and worse physical and mental health. The themes identified here may have important implications for the clinical strategies providers can use to present alcohol-related care options to women Veterans to facilitate their use of care. These strategies include educating women about the health effects of alcohol misuse and increasing providers' knowledge about available care options (within the care organization or the community), including the availability of gender-specific services.

SBIRT-A: Adapting SBIRT to Maximize Developmental Fit for Adolescents in Primary Care

The Screening, Brief Intervention and Referral to Treatment (SBIRT) model is widely recommended as part of routine visits in pediatric primary care despite a dearth of evidence on its effectiveness, feasibility, and developmental appropriateness for adolescents in this setting. The purpose of this article is to explicate ways that SBIRT may be tailored to better serve adolescents in primary care under a set of recommended adaptations that we refer to collectively as SBIRT-A or Screening, Brief Intervention, and Referral to Treatment for Adolescents. Each component of the SBIRT-A framework incorporates recommendations to optimize developmental fit with adolescents based on extant empirical research, developmental theory, and well-documented barriers to service delivery in primary care. Commonalities across proposed adaptations include reliance upon proactive methods to identify and engage youth; innovation in service delivery aimed at improving the consistency and reach of interventions; and a family-focused approach to engagement, assessment, and intervention. Specific recommendations include taking advantage of every clinical encounter with the family to screen, involving caregivers in assessments and brief interventions, leveraging technology to administer brief interventions and booster sessions, and patient- and family-centered procedures for treatment referral and engagement. The adaptations proposed in this article have the potential to enhance the detection of adolescents with SU problems in primary care, the consistency of intervention provision, and engagement of this typically recalcitrant population into appropriate treatment.

Specialty substance use disorder services following brief alcohol intervention: a meta-analysis of randomized controlled trials

BACKGROUND AND AIMS

Brief alcohol interventions in medical settings are efficacious in improving self-reported alcohol consumption among those with low-severity alcohol problems. Screening, Brief Intervention and Referral to Treatment initiatives presume that brief interventions are efficacious in linking patients to higher levels of care, but pertinent evidence has not been evaluated. We estimated main and subgroup effects of brief alcohol interventions, regardless of their inclusion of a referral-specific component, in increasing the utilization of alcohol-related care.

METHODS

A systematic review of English language papers published in electronic databases to 2013. We included randomized controlled trials (RCTs) of brief alcohol interventions in general health-care settings with adult and adolescent samples. We excluded studies that lacked alcohol services utilization data. Extractions of study characteristics and outcomes were standardized and conducted independently. The primary outcome was post-treatment alcohol services utilization assessed by self-report or administrative data, which we compared across intervention and control groups.

RESULTS

Thirteen RCTs met inclusion criteria and nine were meta-analyzed (n = 993 and n = 937 intervention and control group participants, respectively). In our main analyses the pooled risk ratio (RR) was = 1.08, 95% confidence interval (CI) = 0.92-1.28. Five studies compared referral-specific interventions with a control condition without such interventions (pooled RR = 1.08, 95% CI = 0.81-1.43). Other subgroup analyses of studies with common characteristics (e.g. age, setting, severity, risk of bias) yielded non-statistically significant results.

CONCLUSIONS

There is a lack of evidence that brief alcohol interventions have any efficacy for increasing the receipt of alcohol-related services.
