A Qualitative Study of Barriers and Facilitators of PrEP Uptake Among Women in Substance Use Treatment and Syringe Service Programs.

PrEP is an HIV prevention option that could benefit substance-involved women, a high-risk population with low PrEP uptake. Little is known about their interest in PrEP. This qualitative study used in-depth interviews to examine PrEP willingness, barriers, and facilitators among 16 women in outpatient psychosocial substance use treatment, methadone, and/or harm reduction/syringe programs in NYC. All expressed willingness to use PrEP, but only during periods of perceived risk. Women perceived themselves to be at high risk for HIV when engaging in active substance use and/or transactional sex. They perceived themselves to be at low risk and therefore unmotivated to take PrEP when abstinent from these activities. Paradoxically, a major barrier to using PrEP was anticipated interference from substance use and transactional sex, the very same activities that create a perception of risk. Facilitators of PrEP use included perceptions of it as effortless (as opposed to barrier methods during sex) and effective, safe, and accessible. Other barriers included fear of stigma and doubts about adhering daily. Recommendations for best PrEP implementation practices for substance-involved women included tailored and venue-specific PrEP information and messaging, PrEP discussion with trusted medical providers, and on-site PrEP prescription in substance use treatment and harm reduction programs.

RESUMEN: PrEP es una opción de prevención de VIH que puede beneficiar a las mujeres que consumen sustancias, una población de alto riesgo con baja aceptación de la PrEP, pero poco se sabe de su interés en la PrEP. Este estudio cualitativo utilizó entrevistas para examinar el interés en tomar la PrEP y las barreras y los facilitadores del uso de la PrEP entre 16 mujeres en tratamiento por el uso de sustancias en clínicas ambulatorias, clínicas metadonas, o programas de reducción de daños en la ciudad de Nueva York, Estados Unidos. Todas las participantes expresaron su disposición a usar PrEP, pero solo durante períodos de riesgo percibido (por ejemplo, tiempos de uso de sustancias activas y/o sexo transaccional). Paradójicamente, una barrera importante para el uso de PrEP fue la interferencia anticipada por el uso de sustancias y el sexo transaccional, las mismas actividades que crean una percepción de riesgo. Los facilitadores incluyeron percepciones de PrEP como sin esfuerzo durante las relaciones sexuales, efectiva, segura, y accesible. Otras barreras incluyeron el miedo del estigma y dudas sobre la adherencia diaria. Las recomendaciones para las mejores prácticas de implementar la PrEP para mujeres que consumen sustancias incluyeron información y mensajes de PrEP personalizados y específicos del lugar, discusión de PrEP con proveedores médicos confiables, y prescripción de PrEP en el sitio en programas de tratamiento y reducción de daños por uso de sustancias.

Predoctoral substance use disorders curricula: A survey analysis and experiential pedagogy.

Substance Use Disorders (SUD) are chronic health conditions with heritability characteristics, environmental influences, long-term management considerations and they cooccur. The US opioid epidemic is a crisis of both prescription and nonprescription opioid use. Clinicians now have access to evidence-based practices but the evolving trends require continuous attention including curriculum initiatives for dental schools. The purpose of this study was to obtain information about the content and educational strategies of current SUD curricula, beneficial educational products for a standardized curriculum and perceived barriers toward standardization. Invitations were sent to 64 US dental schools describing the purpose of this study and a link to complete the survey was provided. Fully completed responses were received from 32 (50.0%) of the schools. Descriptive statistics was used to analyze the data. Most dental schools surveyed (81.3%) have a curriculum for SUD with classroom lectures being the most commonly used teaching method (96.2%), followed by online modules (42.3%). About 30% of the responding schools provided additional educational experiences. Instruction occurred mostly in second (73.1%) and third (77.0%) academic years. Opioids, alcohol, nicotine, and marijuana were the most frequently taught substance classes. Curriculum standardization with online modules (81.3%), case-based exercises (59.4%), and simulation with standardized patients (43.8%) was considered desirable to improve student competency in the management of patients with SUD. Lack of time (62.5%), space (56.3%), and faculty (50.0%) were cited as the most common barriers to curriculum initiatives. Experiential and achievable options for improving SUD curriculum were highlighted.

The utility of a formative one-station objective structured clinical examination for Substance use disorders in a dental curriculum.

Substance use disorders (SUD) are chronic relapsing medical conditions characterised by compulsive substance seeking and use. They constitute a substantial disease burden globally. Labelling of persons with SUD has created barriers to treatment but there are effective management strategies. The dental profession has embraced reforms designed to address the SUD epidemic by promoting continuing education for practitioners and initiating curriculum changes in dental schools. Screening, Brief Intervention and Referral to Treatment (SBIRT) is an evidence-based model for managing patients with SUD. The use of a formative 1-station Objective Structured Clinical Examination (OSCE) for learning and assessment in SBIRT, operationalised with the MD3 rating scale is presented in this study. In 3 years of implementation, the SBIRT OSCE successfully integrated into the curriculum of the College of Dental Medicine, Columbia University. Mean score of total adherent behaviours was 11.80 (SD =4.23) (range: 2 - 24) and Cronbach's coefficient alpha for across-items reliability in adherent behaviours was 0.66. Adherent behaviours correlated with the global ratings (r = 0.66). Mean of global rating scores were 2.90 (SD =1.01) for collaboration and 2.97 (SD =1.00) for empathy and the global rating scores correlated with each other (r = 0.85). Histograms of global rating scores resembled normal distribution. The 1-station OSCE is a good model for learning about SBIRT. Psychometric analysis was useful in understanding the underlying construct of the MD3 rating scale and supported its reliability, validity and utility in dental education.

Medical Student Attitudes Toward Substance Use Disorders Before and After a Skills-Based Screening, Brief Intervention, and Referral to Treatment (SBIRT) Curriculum.

PURPOSE: Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based framework for assessing and addressing risky substance use. This study evaluated the substance-related attitudes of medical students who participated in an Enhanced Pre-Clinical SBIRT Curriculum designed to reduce stigma, help students empathize with the experiences of people using alcohol and drugs, understand substance use in-context, and feel more optimistic about efforts to prevent and treat substance use disorders (SUDs). METHODS: Students (N=118; 73.8% of eligible) completed the Attitudes and Opinions Survey for alcohol and drugs before and after this 2-year, multi-modality curriculum. The authors classified attitudes as "positive" or "negative" and grouped students by pre-post attitudinal change: persistently negative, persistently positive, negative-to-positive, positive-to-negative. Using chi-square tests, the authors assessed differences by sex, race/ethnicity, and whether students had a family member or friend with an SUD. RESULTS: Most students (>90%) reported persistently positive attitudes regarding physicians in recovery, societal contributions of patients with SUDs; ability to learn from such patients; and general attitudes toward SUD treatment. This skewed distribution precluded the investigation of subgroup differences. Fewer students reported persistently positive attitudes regarding SUD patients' healthcare utilization (alcohol 58.5%; drug 57.8%) and impact on other patients' care (alcohol 73.7%; drug 72.4%), compared to other attitudinal domains (at p-values < 0.0001 in the McNemar's tests). Approximately, 1 in 5 students reported more negative healthcare utilization attitudes on follow-up. There were no demographic differences in these two attitudinal domains. CONCLUSION: Unlike previous studies of medical student attitudes, most students who participated in the Enhanced Pre-Clinical SBIRT Curriculum reported an enduring appreciation for the educational and societal contributions of patients with SUDs. Attitudes toward healthcare utilization and the impact of patients with SUDs on the care of other patients were more resistant to change, possibly due to the predominance of acute-care inpatient settings in clinical training.

The Use of Technology in Participant Tracking and Study Retention: Lessons Learned From a Clinical Trials Network Study.

BACKGROUND: The growing use of newer communication and Internet technologies, even among low-income and transient populations, require research staff to update their outreach strategies to ensure high follow-up and participant retention rates. This paper presents the views of research assistants on the use of cell phones and the Internet to track participants in a multisite randomized trial of substance use disorder treatment. METHODS: Preinterview questionnaires exploring tracking and other study-related activities were collected from 21 research staff across the 10 participating US sites. Data were then used to construct a semistructured interview guide that, in turn, was used to interview 12 of the same staff members. The questionnaires and interview data were entered in Atlas.ti and analyzed for emergent themes related to the use of technology for participant-tracking purposes. RESULTS: Study staff reported that most participants had cell phones, despite having unstable physical addresses and landlines. The incoming call feature of most cell phones was useful for participants and research staff alike, and texting proved to have additional benefits. However, reliance on participants' cell phones also proved problematic. Even homeless participants were found to have access to the Internet through public libraries and could respond to study staff e-mails. Some study sites opened generic social media accounts, through which study staff sent private messages to participants. However, the institutional review board (IRB) approval process for tracking participants using social media at some sites was prohibitively lengthy. Internet searches through Google, national paid databases, obituaries, and judiciary Web sites were also helpful tools. CONCLUSIONS: Research staff perceive that cell phones, Internet searches, and social networking sites were effective tools to achieve high follow-up rates in drug abuse research. Studies should incorporate cell phone, texting, and social network Web site information on locator forms; obtain IRB approval for contacting participants using social networking Web sites; and include Web searches, texting, and the use of social media in staff training as standard operating procedures.

Gender-based Outcomes and Acceptability of a Computer-assisted Psychosocial Intervention for Substance Use Disorders.

BACKGROUND: Digital technologies show promise for increasing treatment accessibility and improving quality of care, but little is known about gender differences. This secondary analysis uses data from a multi-site effectiveness trial of a computer-assisted behavioral intervention, conducted within NIDA's National Drug Abuse Clinical Trials Network, to explore gender differences in intervention acceptability and treatment outcomes. METHODS: Men (n=314) and women (n=192) were randomly assigned to 12-weeks of treatment-as-usual (TAU) or modified TAU+Therapeutic Education System (TES), whereby TES substituted for 2hours of TAU per week. TES is composed of 62 Web-delivered, multimedia modules, covering skills for achieving and maintaining abstinence plus prize-based incentives contingent on abstinence and treatment adherence. Outcomes were: (1) abstinence from drugs and heavy drinking in the last 4weeks of treatment, (2) retention, (3) social functioning, and (4) drug and alcohol craving. Acceptability was the mean score across five indicators (i.e., interesting, useful, novel, easy to understand, and satisfaction). RESULTS: Gender did not moderate the effect of treatment on any outcome. Women reported higher acceptability scores at week 4 (p=.02), but no gender differences were detected at weeks 8 or 12. Acceptability was positively associated with abstinence, but only among women (p=.01). CONCLUSIONS: Findings suggest that men and women derive similar benefits from participating in a computer-assisted intervention, a promising outcome as technology-based treatments expand. Acceptability was associated with abstinence outcomes among women. Future research should explore characteristics of women who report less satisfaction with this modality of treatment and ways to improve overall acceptability.

Acceptability of a web-based community reinforcement approach for substance use disorders with treatment-seeking American Indians/Alaska Natives.

Longstanding disparities in substance use disorders and treatment access exist among American Indians/Alaska Natives (AI/AN). Computerized, web-delivered interventions have potential to increase access to quality treatment and improve patient outcomes. Prior research supports the efficacy of a web-based version [therapeutic education system (TES)] of the community reinforcement approach to improve outcomes among outpatients in substance abuse treatment; however, TES has not been tested among AI/AN. The results from this mixed method acceptability study among a diverse sample of urban AI/AN (N = 40) show that TES was acceptable across seven indices (range 7.8-9.4 on 0-10 scales with 10 indicating highest acceptability). Qualitative interviews suggest adaptation specific to AI/AN culture could improve adoption. Additional efforts to adapt TES and conduct a larger effectiveness study are warranted.

Internet-delivered treatment for substance abuse: a multisite randomized controlled trial.

OBJECTIVE: Computer-delivered interventions have the potential to improve access to quality addiction treatment care. The objective of this study was to evaluate the effectiveness of the Therapeutic Education System (TES), an Internet-delivered behavioral intervention that includes motivational incentives, as a clinician-extender in the treatment of substance use disorders. METHOD: Adult men and women (N=507) entering 10 outpatient addiction treatment programs were randomly assigned to receive 12 weeks of either treatment as usual (N=252) or treatment as usual plus TES, with the intervention substituting for about 2 hours of standard care per week (N=255). TES consists of 62 computerized interactive modules covering skills for achieving and maintaining abstinence, plus prize-based motivational incentives contingent on abstinence and treatment adherence. Treatment as usual consisted of individual and group counseling at the participating programs. The primary outcome measures were abstinence from drugs and heavy drinking (measured by twice-weekly urine drug screens and self-report) and time to dropout from treatment. RESULTS: Compared with patients in the treatment-as-usual group, those in the TES group had a lower dropout rate (hazard ratio=0.72, 95% CI=0.57, 0.92) and a greater abstinence rate (odds ratio=1.62, 95% CI=1.12, 2.35). This effect was more pronounced among patients who had a positive urine drug or breath alcohol screen at study entry (N=228) (odds ratio=2.18, 95% CI=1.30, 3.68). CONCLUSIONS: Internet-delivered interventions such as TES have the potential to expand access and improve addiction treatment outcomes. Additional research is needed to assess effectiveness in non-specialty clinical settings and to differentiate the effects of the community reinforcement approach and contingency management components of TES.

Characteristics of an outpatient treatment sample by primary substance of abuse.

OBJECTIVE: This study examines sociodemographic and clinical characteristics, as a function of primary substance of abuse, among clients approached, screened, and assessed for eligibility in a 10-site effectiveness trial of a Web-based psychosocial intervention for substance use disorders. Consistent with the design of effectiveness trials, eligibility criteria were broad and exclusion criteria minimal; thus, the recruited sample may be viewed as relatively representative of patients seeking treatment throughout the United States. METHODS: χ tests for categorical variables and F tests for continuous variables were used to analyze demographic, substance use, physical and mental health, and sexual risk data collected at screening and baseline; pairwise comparisons between primary substance subgroups for baseline data were conducted if the test statistic P value was 0.01 or less. RESULTS: Few participants expressed disinterest in the study at screening because of the computer-assisted intervention. A diverse sample of substance users completed baseline and were enrolled: 22.9% marijuana; 21.7% opiates; 20.9% alcohol; 20.5% cocaine; and 13.9% stimulants users. Marijuana users demonstrated the greatest differences across primary substances: they were younger, less likely to be married or attend 12-step meetings, and more likely to be in treatment as a result of criminal justice involvement. All patients, even marijuana users, reported comparable rates of co-occurring mental health disorders and sexual risk and substantial rates of polysubstance use disorders. CONCLUSIONS: Primary substance of abuse may be a less important indicator of overall severity compared with co-occurring disorders and other factors common across treatment seekers, further demonstrating the need for integrated treatment services and care and comprehensive pretreatment assessment.

Design and methodological considerations of an effectiveness trial of a computer-assisted intervention: an example from the NIDA Clinical Trials Network.

Computer-assisted interventions hold the promise of minimizing two problems that are ubiquitous in substance abuse treatment: the lack of ready access to treatment and the challenges to providing empirically-supported treatments. Reviews of research on computer-assisted treatments for mental health and substance abuse report promising findings, but study quality and methodological limitations remain an issue. In addition, relatively few computer-assisted treatments have been tested among illicit substance users. This manuscript describes the methodological considerations of a multi-site effectiveness trial conducted within the National Institute on Drug Abuse's (NIDA's) National Drug Abuse Treatment Clinical Trials Network (CTN). The study is evaluating a web-based version of the Community Reinforcement Approach, in addition to prize-based contingency management, among 500 participants enrolled in 10 outpatient substance abuse treatment programs. Several potential effectiveness trial designs were considered and the rationale for the choice of design in this study is described. The study uses a randomized controlled design (with independent treatment arm allocation), intention-to-treat primary outcome analysis, biological markers for the primary outcome of abstinence, long-term follow-up assessments, precise measurement of intervention dose, and a cost-effectiveness analysis. Input from community providers during protocol development highlighted potential concerns and helped to address issues of practicality and feasibility. Collaboration between providers and investigators supports the utility of infrastructures that enhance research partnerships to facilitate effectiveness trials and dissemination of promising, technologically innovative treatments. Outcomes from this study will further the empirical knowledge base on the effectiveness and cost-effectiveness of computer-assisted treatment in clinical treatment settings.

Smoking cessation treatment among patients in community-based substance abuse rehabilitation programs: exploring predictors of outcome as clues toward treatment improvement.

BACKGROUND: Predictors of smoking cessation (SC) treatment outcome were explored in a multisite clinical trial of SC treatment at community-based, outpatient, substance abuse rehabilitation programs affiliated with the National Drug Abuse Treatment Clinical Trials Network. OBJECTIVES: To explore baseline demographic and clinical predictors of abstinence during treatment. METHODS: Cigarette smokers from five methadone maintenance programs and two drug and alcohol dependence treatment programs were randomly assigned to SC treatment as an adjunct to substance abuse treatment as usual or to substance abuse treatment as usual. SC treatment consisted of group counseling (weeks 1-8) plus transdermal nicotine patch treatment (21 mg/day, weeks 1-6; 14 mg/day, weeks 7-8). Demographic and clinical predictors of smoking abstinence were evaluated among those patients assigned to the active SC condition (N = 153) using logistic regression. RESULTS: Abstinence during treatment was positively associated with younger age, Hispanic or Caucasian (as opposed to African American) ethnicity/race, employment or student status, fewer cigarettes per day at baseline, lower severity of the primary substance problem at baseline, and higher methadone doses (among the subsample in methadone treatment). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: During future efforts to improve SC treatments among drug- and alcohol-dependent patients, consideration should be given to adequate treatment to reduce the severity of the primary drug or alcohol problem, tailoring treatments for patients with greater severity of smoking and of the primary substance problem, and culturally sensitive interventions. Analysis of predictors of outcome may be a useful tool for treatment development.
