Substance use Attitudes, Beliefs, Experience, and Knowledge Among Nursing and Nursing Assistant Students.

Stigma is a public health concern. Stigmatizing attitudes toward persons with substance use disorders (SUDs) can adversely impact clinical care and outcomes. Beliefs about SUD, prior experience and familiarity to persons with SUD, and educational curricula drive attitudes among health-care workers. In 2019, nursing and nursing assistant students were recruited through an online survey platform. Participants completed an SUD knowledge test and a survey assessing education, beliefs, personal experience, and confidence in recognizing the signs and symptoms of SUD. One hundred and ten health-care students (nursing students, n = 67 and nursing assistant students, n = 43) completed the survey. Among nursing assistant students, endorsing a disease model of addiction (F(2, 40) = 5.83, p < .001, R2 = .23), and personal familiarity with SUD (F(2, 40) = 4.46, p < .001, R2 = .18), were significantly positively predictive of positive regard toward working with persons with SUD. For nursing students, endorsing a disease model of addiction, educational curricula involving persons with SUD, and personal familiarity were significantly positively predictive of positive regard toward working with persons with SUDs (F(2, 61) = 11.52, p < .001, R2 = .36). Interventions to mitigate drug-related stigma among health-care students should center students with personal familiarity, promote the disease concept of addiction, and incorporate contact-based training.

A Pragmatic, Person-Centered View of Cannabis in the United States: Pursuing Care That Transcends Beliefs.

BACKGROUND: Rates of cannabis use are increasing in the United States, likely as a result of changes in societal attitudes and expanding legalization. Although many patients report wanting to discuss the risks and benefits of cannabis use with their clinical providers, many providers hold conflicting beliefs regarding cannabis use and often do not engage patients in discussion about cannabis. This dilemma is underscored by the limitations imposed on cannabis related research, and lack of empirically based best-practice guidelines for clinicians when addressing cannabis use with patients. OBJECTIVES: We aimed to briefly summarize clinician and patient attitudes toward cannabis use and review current clinical guidelines and provide suggestions to assist health care providers and clinicians in increasing their comfort and skill in discussing cannabis use with patients. METHODS: A narrative review on attitudes toward cannabis use and clinical guidelines was performed to summarize the literature and provide evidence-based recommendations. RESULTS: Attitudes toward cannabis use have been shaped by personal and political factors and contribute to clinician hesitance in speaking with patients about the topic. Administrative barriers have hindered the development of clearer public health guidelines that might enable the dissemination of evidence-based information on the health effects of cannabis use and might ultimately lead to better health outcomes. CONCLUSION: Not discussing cannabis use with patients may be a crucial missed opportunity for harm reduction. In the absence of empirically supported best-practice guidelines, a person-centered approach can facilitate conversations on the harms and benefits of cannabis use.

Ethical Dilemmas Facing Substance Use Counselors During the COVID-19 Pandemic.

Introduction: During the COVID-19 pandemic, substance use disorder (SUD) treatment settings experienced several abrupt changes, including decreased admissions, reduction in services, and modified requirements for medication for substance use disorder. While these changes were implemented to facilitate the maintenance of important treatment options, the ethical consequences of such changes remained unknown. The current study aimed to explore ethical issues related to COVID-19-related changes reported by counselors in SUD treatment facilities. Method: From May to August 2020, we conducted 60 to 90 minutes in-depth interviews with 18 front-line staff in 1 residential and 1 outpatient treatment program, exploring issues drawn from the ethical principles of the national organization representing SUD counselors. Counselors volunteered to participate via phone or email, and participation was confidential. Interviews were conducted via videoconferencing. Topics included day-to-day experiences of ethical dilemmas in the workplace, particularly during the COVID-19 era. Interviews were recorded, transcribed, and checked for accuracy and a trained team of analysts then coded transcripts using thematic analysis. Results: As a result of the COVID-19 pandemic, SUD treatment programs quickly modified procedures to adhere to public health mandates while also continuing to offer care to clients. SUD counselors reported several ways their programs adapted new and creative procedures to reduce the risk of COVID-19 transmission. SUD counselors also identified several novel ethical dilemmas that occurred during the COVID-19 pandemic, often resulting from the counselor balancing the needs for responding to public health mandates with providing services to clients. There were several ways that COVID-19 related changes resulted in therapeutic challenges for some clients, and the SUD counselors highlighted ways that changes resulted in more flexible services for other clients. Conclusions: This study highlights the quick response to COVID-19 that occurred within SUD treatment. While these changes resulted in novel ethical dilemmas, they also offered more flexible and client-centered approaches to treatment.

HIV clinic-based extended-release naltrexone versus treatment as usual for people with HIV and opioid use disorder: a non-blinded, randomized non-inferiority trial.

BACKGROUND AND AIM: Opioid agonist medications for treatment of opioid use disorder (OUD) can improve human immunodeficiency virus (HIV) outcomes and reduce opioid use. We tested whether outpatient antagonist treatment with naltrexone could achieve similar results. DESIGN: Open-label, non-inferiority randomized trial. SETTING: Six US HIV primary care clinics. PARTICIPANTS: A total of 114 participants with untreated HIV and OUD (62% male; 56% black, 12% Hispanic; positive for fentanyl (62%), other opioids (47%) and cocaine (60%) at baseline). Enrollment halted early due to slow recruitment. INTERVENTION: HIV clinic-based extended-release naltrexone (XR-NTX; n = 55) versus treatment as usual (TAU) with buprenorphine or methadone (TAU; n = 59). MEASUREMENTS: Treatment group differences were compared for the primary outcome of viral suppression (HIV RNA ≤ 200 copies/ml) at 24 weeks and secondary outcomes included past 30-day use of opioids at 24 weeks. FINDINGS: Fewer XR-NTX participants initiated medication compared with TAU participants (47 versus 73%). The primary outcome of viral suppression was comparable for XR-NTX (52.7%) and TAU (49.2%) [risk ratio (RR) = 1.064; 95% confidence interval (CI) = 0.748, 1.514] at 24 weeks. Non-inferiority could not be demonstrated, as the lower confidence limit of the RR did not exceed the pre-specified margin of 0.75 in intention-to-treat (ITT) analysis. The main secondary outcome of past 30-day opioid use was comparable for XR-NTX versus TAU (11.7 versus 14.8 days; mean difference = -3.1; 95% CI = -8.7, 1.1) in ITT analysis. Among those initiating medication, XR-NTX resulted in fewer days of opioid use compared with TAU in the past 30 days (6.0 versus 13.6, mean difference = -7.6; 95% CI = -13.8, -0.2). CONCLUSIONS: A randomized controlled trial found supportive, but not conclusive, evidence that human immunodeficiency virus clinic-based extended-release naltrexone is not inferior to treatment as usual for facilitating human immunodeficiency virus viral suppression. Participants who initiated extended-release naltrexone used fewer opioids than those who received treatment as usual.

Legalization of cannabis in Canada-Local media analysis.

BACKGROUND AND OBJECTIVES: Legalization of recreational cannabis is occurring across the United States, with some controversy. To understand the range of issues that can arise when such a policy change is enacted, we examined portrayal of legalization at the local level by studying newspaper articles in Calgary, Alberta, shortly before and after cannabis legalization in Canada. METHOD: We searched the largest-circulation newspaper for cannabis-related items and analyzed for content and slant toward cannabis legalization. RESULTS: Among 165 items, business/economics (70.9% of items) and legalization (69.7%) were most frequent, with health only 29.7%. Across all items, the slant was more approval (44.2%) than disapproval (23.0%). DISCUSSION AND CONCLUSIONS: When cannabis was legalized, the local newspaper focused more on economic aspects of legalization rather than about health issues. Further research can determine the generalizability of the findings to other locales and provide comparison as other similar policy changes roll out. SCIENTIFIC SIGNIFICANCE: The study provides new information on what happens when drug policies are enacted. Documenting the media portrayal of substance use policies is a promising tool.

Views of barriers and facilitators to continuing methadone treatment upon release from jail among people receiving patient navigation services.

BACKGROUND: Patient navigation has potential for assisting patients who initiate methadone during pretrial detention to enter and remain in treatment following release, but we know little about participants' experiences with this service. METHODS: This study drew a purposive sample of male and female participants (N = 17) from participants enrolled in a randomized trial of initiating methadone with vs. without patient navigation while in the Baltimore City Detention Center. The study interviewed participants in the community at 1 and 3 months following release and asked them about their experiences of reentry, methadone treatment continuation, drug use, and interactions with the patient navigator. The study recorded, transcribed, coded using Atlas.ti, and analyzed thematically the interviews. RESULTS: Participants reported encountering four key challenges in the community: getting to treatment following release, assembling basic supports, managing criminal justice system demands, and staying in treatment. Participants' experiences of the patient navigator's support to address these challenges fell into six thematic groups: showing nonjudgmental caring and persistence, advocating within programs, brokering resources, managing interactions with the criminal justice system, balancing encouragement and self-determination, and offering genuine and familial-type support. CONCLUSION: Nearly all participants appreciated the navigator's support and deemed it helpful. The previously reported randomized trial found that participants assigned to initiate methadone treatment with navigation had higher rates of receiving their first "guest" methadone dose in the community but did not have significantly different rates of treatment enrollment or of illicit opioid use compared to those assigned to begin methadone treatment without navigation. Treatment programs should work to improve retention and postrelease outcomes among this population.

Discontinuing Methadone and Buprenorphine: A Review and Clinical Challenges.

This paper offers a review and recommendations for clinicians working with patients interested in discontinuing opioid agonist treatment. As buprenorphine/naloxone has gained widespread acceptance for opioid addiction, many treatment providers and patients have a range of hopes and expectations about its optimal use. A surprising number assume buprenorphine/naloxone is primarily useful as a medication to transition off illicit opioid use, and success is partially defined by discontinuing the medication. Despite accumulating evidence that a majority of patients will need to remain on medication to preserve their gains, clinicians often have to address a patient's fervent desire to taper. Using the concept of "recovery capital," our review addresses (1) the appropriate duration of opioid agonist treatment, (2) risks associated with discontinuing, (3) a checklist that guides the patient through self-assessment of the wisdom of discontinuing opioid agonist treatment, and (4) shared decision making about how to proceed.

PTSD / substance use disorder comorbidity: Treatment options and public health needs.

Purpose of Review: Posttraumatic stress disorder (PTSD) commonly co-occurs with substance use disorder (SUD) and is challenging to treat. We review all behavioral therapy models with at least one randomized controlled trial in a current PTSD/SUD population. We identify factors in selecting a model for clinical use, emphasizing a public health framework that balances the need for evidence with the need for feasibility in frontline settings. Recent Findings: Seven published models and 6 unpublished models are reviewed. Public health considerations for choosing a model include: whether it's been studied across a broad range of SUDs and in complex SUD patients; whether it can be conducted in group modality; its appeal to patients and providers; its cost; workforce requirements; and its ability to reduce substance use in addition to PTSD. Summary: There are two broad types of models: those that originated in the PTSD field versus the SUD field. Overall, the latter are stronger on public health factors and more feasible in SUD settings. Published models in this category include Relapse Prevention, BRENDA, and Seeking Safety. PTSD/SUD research is at an early stage and there is a need for methodology that quantifies "level of burden" (patients' socioeconomic disadvantages) across trials.

Enhancing patient navigation with contingent financial incentives for substance use abatement in persons with HIV and substance use.

Substance use can interfere with HIV treatment. A previous multisite clinical trial (Metsch et al., 2016) tested 2 behavioral interventions designed to improve treatment engagement in people with comorbid HIV and drug or heavy alcohol use. Clinical trial participants were randomized to treatment as usual (N = 264), patient navigation (PN; N = 266), or PN with contingency management (PN + CM; N = 271) for 6 months. PN + CM patients could earn financial incentives both for entering substance use disorder (SUD) treatment and for submitting urine and breath samples negative for opioids, stimulants, and alcohol. This secondary analysis compared frequencies of treatment entry and sample submission in the PN versus PN + CM groups and examined associations with viral suppression (defined as ≤200 copies/mL). Incentives were associated with a higher percentage of patients entering SUD treatment (PN = 25.5%; PN + CM = 47.6%; p < .001), a higher percentage submitting samples for drug testing (PN median = 2, interquartile range [IQR] = 0.5; PN + CM median = 8, IQR = 5.1; p < .0001) and a higher percentage submitting samples negative for targeted drugs and alcohol (PN median = 1, IQR = 0.3; PN + CM median = 6, IQR = 2.9; p < .0001). Within the PN + CM group, up to 58% of those with high rates of engagement in activities were virally suppressed at 6 months versus 24-29% in subgroups with lowest engagement. In conclusion, CM was feasibly incorporated into PN for persons with HIV and SUD and was associated with higher rates of engagement in targeted substance use abatement activities. CM has the potential to improve health outcomes in this population. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Health-related internet use among opioid treatment patients.

The Internet and smartphones have become commonplace and can be effective in overcoming traditional barriers to accessing health information about substance use disorders (SUD), and their prevention or treatment. Little is known, however, about specific factors that may influence the use of these technologies among socioeconomically disadvantaged populations with SUDs. This study characterized the use of digital technologies and the Internet among individuals receiving treatment for opioid use disorder, focusing on identifying predictors of Internet use for health-related purposes. Participants came from an urban opioid replacement therapy program and completed a face-to-face survey on Internet and technology use. We examined the association between online health information seeking and technology acceptance variables, including perceived usefulness, effort expectancy, social influence, and facilitating conditions (e.g., availability of devices/services and technical support). Participants (N = 178, ages 18-64) endorsed high rates of current smartphone ownership (94%) and everyday Internet use (67%). 88% of participants reported searching online for information about health or medical topics in the past 3 months. Predictors of Internet use for health-related purposes were higher technology acceptance for mobile Internet use, younger age, current employment, and less bodily pain. Our results demonstrate high acceptance and use of mobile technology and the Internet among this sample of socioeconomically disadvantaged individuals with SUDs. However, these findings also highlight the importance of identifying barriers that disadvantaged groups face in using mobile technologies when designing technology-based interventions for this population.

Physician Mistrust, Medical System Mistrust, and Perceived Discrimination: Associations with HIV Care Engagement and Viral Load.

Medical mistrust is an important risk factor for many health outcomes. For individuals with HIV and substance use co-morbidities, mistrust may influence engagement with health care, and affect overall health and transmission risk. Medical mistrust can be measured by an individual's mistrust of his/her physician, or mistrust of the medical system. This study examined both types of mistrust among 801 substance-using individuals with uncontrolled HIV infection. The aims were to determine how physician mistrust, medical system mistrust, and discrimination experiences were associated with engagement in HIV primary care. Findings indicated higher levels of physician mistrust, but not medical system mistrust, were associated with a longer time since the last visit to an HIV provider. Longer time since seeing an HIV care provider was associated with higher viral load. This study refines our understanding of the relationship between mistrust and HIV care engagement for a large, diverse sample of substance-using individuals.

How patient navigators view the use of financial incentives to influence study involvement, substance use, and HIV treatment.

BACKGROUND AND AIMS: While patient navigation has been shown to be an effective approach for linking persons to HIV care, and contingency management is effective at improving substance use-related outcomes, Project HOPE combined these two interventions in a novel way to engage HIV-positive patients with HIV and substance use treatment. The aims of this paper are to examine patient navigator views regarding how contingency management interacted with and affected their navigation process. DESIGN: Semi-structured qualitative interviews. PARTICIPANTS: 22 patient navigators from the original 10 Project HOPE study sites. MEASUREMENTS: Individual, semi-structured interviews lasting approximately 60 min addressed the patient navigator's professional background, descriptions of the participant population, substance use disorder versus HIV treatment entry and engagement issues, and the use of contingency management within the navigation service delivery protocol. FINDINGS: Patient navigators believed that financial incentives helped motivate participant attendance at navigation sessions, particularly early in study involvement, which helped them to establish rapport and develop relationships with participants. Patient navigators often noted that financial incentives positively influenced targeted HIV health-related behaviors, such as attending medical appointments, which provided a rapid pay-off with an escalating sum. Contingency management was more complex when used by the patient navigators for substance use-related behaviors, particularly when incentives revolved around negative urine screening. Patient navigators noted that not all participants responded the same way to the contingency management and that the incentives were particularly helpful when participants were financially strained with limited resources or when internal motivation was lacking. CONCLUSIONS: Overall patient navigators found the inclusion of contingency management to be helpful and affective at influencing participant behaviors, particularly concerning navigation session attendance and HIV healthcare-related participation. However, issues and concerns surrounding the inclusion of contingency management for drug-related behaviors as delivered in Project HOPE were noted. CLINICAL TRIALS REGISTRATION: NCT01612169.

Process Evaluation of a Community Outpatient Program Treating Substance Use Disorders.

Addiction treatment can improve its impact by providing evidence-based care for the variety of problems that accompany substance use disorders. We conducted a retrospective evaluation of a new treatment program in California that aimed at providing multifaceted services through affiliated licensed and certified outpatient providers. The process evaluation used a logic model, focusing on program inputs, activities, and outputs, to understand the services received by the initial 18 clients who entered treatment. Outcomes for these patients were not assessed. Results indicated that clients received a variety of services: On average clients contracted for 118 treatment sessions and received 143 sessions. Among the many types of services provided, the most frequently received were integrative healthcare (averaging 42 sessions), group therapy (32 sessions), and individual therapy (32 sessions). This logic-model process evaluation indicated that a range of services were provided. The comprehensive approach may have promise for extending addiction treatment beyond its usual boundaries.

Enhancing Patient Navigation with Contingent Incentives to Improve Healthcare Behaviors and Viral Load Suppression of Persons with HIV and Substance Use.

This secondary analysis compares health behavior outcomes for two groups of HIV+ substance users randomized in a 3-arm trial [1] to receive Patient Navigation with (PN+CM) or without (PN) contingent financial incentives (CM). Mean age of participants was 45 years; the majority was male (67%), African American (78%), unemployed (35%), or disabled (50%). Behaviors incentivized for PN+CM were (1) attendance at HIV care visits and (2) verification of an active HIV medication prescription. Incentives were associated with shorter time to treatment initiation and higher rates of behaviors during the 6-month intervention with exception of month 6 HIV care visits. Median HIV care visits were 3 (IQR 2-4) for PN+CM versus 1.5 (IQR 0-3) for PN (Wilcoxon p < 0.001); median validated medication checks were 4 (IQR 2-6) for PN+CM versus 1 (IQR 0-3) for PN (Wilcoxon p < 0.001). Viral suppression rates at end of treatment were not significantly different for the two groups but were directly related to the number of behaviors completed for both care visits (χ2(1) = 7.69, p = 0.006) and validated medication (χ2(1) = 8.49, p = 0.004). Results support use of incentives to increase performance of key healthcare behaviors. Adjustments to the incentive program may be needed to achieve greater rates of sustained health behavior change that result in improved viral load outcomes.

Temporal Relationship of Sex Risk Behaviors and Substance Use Severity Among Men in Substance Use Treatment.

Sex risk behaviors and substance use are intertwined. Many men continue to engage in high-risk sexual behaviors even when enrolled in substance use disorder (SUD) treatment. We hypothesized that changes in sex risk behaviors would coincide with changes in drug/alcohol use severity among men in SUD treatment. During an HIV risk-reduction trial, men in methadone maintenance and outpatient drug-free treatment (N = 359) completed assessments at baseline and six months after. We assessed changes in sex risk and substance use severity, using the Addiction Severity Index-Lite (ASI-Lite), controlling for treatment condition. In multinomial logistic regressions, decreased alcohol severity was significantly associated with decreases in reported sex partners, and increased alcohol severity was significantly associated with increases in reported sex partners. Increasing drug use severity was significantly associated with maintaining and initiating sex with a high-risk partner, while decreasing alcohol use severity was significantly associated with discontinuing sex under the influence. However, changes in drug/alcohol use severity were not associated with changes in unprotected sex. Substance use reductions may decrease HIV risk behaviors among male substance users. Our findings highlight the importance of integrating interventions in SUD treatment settings that address the intersection of sex risk behaviors and substance use.

Structural factors affecting Asians and Pacific Islanders in community-based substance use treatment: Treatment provider perspectives.

Asians and Pacific Islanders (API) have large disparities in utilization of substance use treatment compared to other racial groups. In this study, we analyzed factors that shape API experiences accessing and engaging in community-based treatment from the perspective of treatment providers. We conducted semi-structured interviews with 40 treatment providers who work with API clients in treatment programs in San Francisco and Los Angeles. We analyzed the transcribed interview data in ATLAS.ti using a content analysis approach. There were three main findings. First, treatment providers found the API category itself is too broad and heterogeneous to meaningfully explain substance use patterns. Second, beyond race/ethnicity, structural factors such as poverty, neighborhood, housing, and age had an impact on API substance use. Third, factors such as family, immigration status, religion, language, stigma played complex roles in API treatment experiences, contingent on how client, programs, and providers attended to differences in these categories.

Fair hearing outcomes of patients recommended discharge from methadone maintenance.

A system known as fair hearings is a due process opportunity for patients who are involuntarily discharged from methadone maintenance treatment to challenge the discharge recommendation. We know very little about the processes and outcomes of fair hearings. For this study, we used a mixed methods approach to retrospectively analyze 73 fair hearing reports that were documented from a California methadone maintenance treatment program between 2000 and 2014. The aims of the study were to identify the reasons for involuntary discharge recommendation from methadone maintenance, describe the factors involved when fair hearing outcomes decided in favor of the clinic, and describe the factors involved when fair hearing outcomes decided in favor of the patient. We found that patient attendance at the fair hearing meeting was significantly related to the outcome ruling in favor of the patient. We organized the reasons for discharge recommendations into five categories: 1) suspected diversion, 2) behavioral/interpersonal, 3) repeated, unexcused absences, 4) co-occurring substance use, and 5) multiple sources of opioids. For each category, we use excerpts from fair hearing reports to provide context to the circumstances involved in an outcome favoring the patient or the clinic.

Enhancing patient navigation to improve intervention session attendance and viral load suppression of persons with HIV and substance use: a secondary post hoc analysis of the Project HOPE study.

BACKGROUND: Interventions are needed to improve viral suppression rates among persons with HIV and substance use. A 3-arm randomized multi-site study (Metsch et al. in JAMA 316:156-70, 2016) was conducted to evaluate the effect on HIV outcomes of usual care referral to HIV and substance use services (N = 253) versus patient navigation delivered alone (PN: N = 266) or together with contingency management (PN + CM; N = 271) that provided financial incentives targeting potential behavioral mediators of viral load suppression. AIMS: This secondary analysis evaluates the effects of financial incentives on attendance at PN sessions and the relationship between session attendance and viral load suppression at end of the intervention. METHODS: Frequency of sessions attended was analyzed over time and by distribution of individual session attendance frequency (PN vs PN + CM). Percent virally suppressed (≤200 copies/mL) at 6 months was compared for low, medium and high rate attenders. In PN + CM a total of $220 could be earned for attendance at 11 PN sessions over the 6-month intervention with payments ranging from $10 to $30 under an escalating schedule. RESULTS: The majority (74%) of PN-only participants attended 6 or more sessions but only 28% attended 10 or more and 16% attended all eleven sessions. In contrast, 90% of PN + CM attended 6 or more visits, 69% attended 10 or more and 57% attended all eleven sessions (attendance distribution χ2[11] = 105.81; p < .0001). Overall (PN and PN + CM participants combined) percent with viral load suppression at 6-months was 15, 38 and 54% among those who attended 0-5, 6-9 and 10-11 visits, respectively (χ2(2) = 39.07, p < .001). CONCLUSION: In this secondary post hoc analysis, contact with patient navigators was increased by attendance incentives. Higher rates of attendance at patient navigation sessions was associated with viral suppression at the 6-month follow-up assessment. Study results support use of attendance incentives to improve rates of contact between service providers and patients, particularly patients who are difficult to engage in care.

Perceived discrimination among racial and ethnic minority drug users and the association with health care utilization.

People who use drugs (PWUDs) are at increased risk for several medical conditions, yet they delay seeking medical care and utilize emergency departments (EDs) as their primary source of care. Limited research regarding perceived discrimination and PWUDs' use of health care services exists. This study explores the association between interpersonal and institutional racial/ethnic and drug use discrimination in health care settings and health care utilization among respondents (N = 192) recruited from methadone maintenance treatment programs (36%), HIV primary care clinics (35%), and syringe exchange programs (29%) in New York City (n = 88) and San Francisco (n = 104). The Kaiser Family Foundation Survey of Race, Ethnicity, and Medical Care questionnaire was utilized to assess perceived institutional racial/ethnic and drug use discrimination. Perceived institutional discrimination was examined across race/ethnicity and by regular use of ERs, having a regular doctor, and consistent health insurance. Perceived interpersonal discrimination was examined by race/ethnicity. Perceived interpersonal drug use discrimination was the most common type of discrimination experienced in health care settings. Perceptions of institutional discrimination related to race/ethnicity and drug use among non-Hispanic Whites did not significantly differ from those among non-Hispanic Blacks or Hispanics. A perception of less frequent institutional racial/ethnic and drug use discrimination in health care settings was associated with increased odds of having a regular doctor. Awareness of perceived interpersonal and institutional discrimination in certain populations and the effect on health care service utilization should inform future intervention development to help reduce discrimination and improve health care utilization among PWUDs.

Feasibility and safety of extended-release naltrexone treatment of opioid and alcohol use disorder in HIV clinics: a pilot/feasibility randomized trial.

BACKGROUND AND AIMS: HIV-infected people with substance use disorders are least likely to benefit from advances in HIV treatment. Integration of extended-release naltrexone (XR-NTX) into HIV clinics may increase engagement in the HIV care continuum by decreasing substance use. We aimed to compare (1) XR-NTX treatment initiation, (2) retention and (3) safety of XR-NTX versus treatment as usual (TAU) for treating opioid use disorder (OUD) and/or alcohol use disorder (AUD) in HIV clinics. DESIGN: Non-blinded randomized trial of XR-NTX versus pharmacotherapy TAU. SETTING: HIV primary care clinics in Vancouver, BC, Canada and Chicago, IL, USA. PARTICIPANTS: Fifty-one HIV-infected patients seeking treatment for OUD (n = 16), AUD (n = 27) or both OUD and AUD (n = 8). MEASUREMENTS: Primary outcomes were XR-NTX initiation (receipt of first injection within 4 weeks of randomization) and retention at 16 weeks. Secondary outcomes generated point estimates for change in substance use, HIV viral suppression [HIV RNA polymerase chain reaction (pcr) < 200 copies/ml] and safety. FINDINGS: Two-thirds (68%) of participants assigned to XR-NTX initiated treatment, and 88% of these were retained on XR-NTX at 16 weeks. In comparison, 96% of TAU participants initiated treatment, but only 50% were retained on medication at 16 weeks. Mean days of opioid use in past 30 days decreased from 17.3 to 4.1 for TAU and from 20.3 to 7.7 for XR-NTX. Mean heavy drinking days decreased from 15.6 to 5.7 for TAU and 12.5 to 2.8 for XR-NTX. Among those with OUD, HIV suppression improved from 67 to 80% for XR-NTX and 58 to 75% for TAU. XR-NTX was well tolerated, with no precipitated withdrawals and one serious injection-site reaction. CONCLUSIONS: Extended-release naltrexone (XR-NTX) is feasible and safe for treatment of opioid use disorder and alcohol use disorder in HIV clinics. Treatment initiation appears to be lower and retention greater for XR-NTX compared with treatment as usual (clinicaltrials.gov NCT01908062).
