Barriers and facilitators to recruitment and enrollment of HIV-infected individuals with opioid use disorder in a clinical trial

Engaging the Great Circle: a qualitative study of the Confederated Tribes of Grand Ronde’s mobile medication unit

BACKGROUND

The Confederated Tribes of the Grand Ronde Community of Oregon began a Mobile Medication Unit (MMU) as part of their Great Circle Recovery Opioid Treatment Program (OTP) to address elevated rates of opioid use disorder (OUD) among American Indians and Alaska Natives in Oregon. The MMU provides methadone or buprenorphine for individuals with OUD, enrolled in the OTP, who are living either on the reservation or in surrounding rural communities. An implementation study describes the service through document review and qualitatively assesses patient and staff experiences and the perceived barriers and facilitators to mobile services.

METHODS

Semi-structured qualitative interviews with patients (n = 11), MMU staff (n = 5), and the state opioid treatment authority (n = 1) gathered details on the initiative's development and operations. Provider interviews probed implementation experiences. Patient interviews focused on their experiences with the MMU and staff, changes in quality of life and recommendations for enhancing treatment. Interviews were transcribed and analysed using a Thematic Analysis approach.

RESULTS

Staff themes identified two driving forces (i.e. staff desire for an inclusive approach to wellness that is accessible to all community members; the catalysts for the MMU), two steps toward MMU development (i.e. Tribal approvals and support; the construction and maintenance of community relationships) and two perspectives on MMU implementation and impact (i.e. initial implementation barriers; facilitators and observations of how the MMU reduced stigma associated with agonist therapy). Patients' themes noted the MMU's professional and 'caring' environment, accessible rural locations and general suggestions including culturally responsive ancillary services.

CONCLUSION

The Great Circle MMU enhanced access to opioid agonist therapy for people with OUD (i.e. American Indians/Alaska Natives, and non-natives) living in rural communities. The Confederated Tribes of Grand Ronde operates the first Tribally owned OTP MMU, grounded in cultural humility and committed to Tribal members and the great circle of the larger community.

Engaging Diverse African American/Black and Latine Youth and Emerging Adults Living with HIV into Research: Description of Recruitment Strategies and Lessons Learned

Improving engagement along the HIV care continuum and reducing racial/ethnic disparities are necessary to end the HIV epidemic. Research on African American/Black and Latine (AABL) younger people living with HIV (LWH) is essential to this goal. However, a number of key subgroups are challenging to locate and engage, and are therefore under-represented in research. Primary among these are persons with non-suppressed HIV viral load, severe socioeconomic disadvantage, transgender/gender expansive identities, and refugee/migrant/immigrant populations. Research in community settings is needed to complement studies conducted in medical institutions. The present study describes the efficiency of recruitment strategies used in the community to enroll AABL young and emerging adults LWH ages 19-28 years. Strategies were designed to be culturally responsive and structurally salient. They were: peer-to-peer, social media, classified advertisements (newspaper, craigslist), subway ads, dating apps (Jack'd, Positive Singles), and direct recruitment in community-based organizations. Data were analyzed using mainly descriptive statistics and interpreted using a consensus building approach. We screened 575 individuals in a first step, 409 were eligible (71%), of these 297 presented to the second screening step (73%), but 112 were lost. Almost all presenting at the second step were eligible (98%, 291/297) and 94% enrolled (274/291). Peer-to-peer, dating app (Jack'd), direct recruitment, and craigslist were the most efficient strategies. Recruitment on dating apps was superior to the peer-to-peer approach in yielding eligible participants (OR = 1.5; 95% CI: 0.98-2.3; p = 0.06). The sample enrolled was diverse with respect to HIV viral suppression, gender identify, sexual orientation, immigration status, and barriers to HIV care engagement. We discuss the advantages and disadvantages of each strategy. Recruitment is a vital aspect of research and warrants attention in the empirical literature.

"When selling anything to an audience, visible publicity is key:" experiences, barriers, and enablers to participate in a COVID-19 study in Malawi

BACKGROUND

Many studies in infectious diseases struggle to recruit participants. The SARS-CoV-2 infection, transmission dynamics, and household impact in Malawi (SCATHIM) study reported a refusal rate of 57.2%. Adequate publicity can lead to more people participating in studies. This study explored the reasons for participating in the SCATHIM study.

METHODS

A descriptive qualitative study informed by the theory of reasoned action was conducted in Blantyre between January 2022 and March 2022 to assess factors that influence participation in a COVID-19 study among 10 index cases, 10 caregivers, 10 study decliners, and 5 research staff. The data were collected via in-depth interview guides, audio recorded, transcribed, managed via NVIVO and analysed via a thematic approach.

RESULTS

The factors that motivated participation in the study included one's knowledge of COVID-19; potential access to medical services, including free COVID-19 tests for members of the household; financial reimbursements; and the ability to contribute scientific knowledge. The barriers to participation included minimal publicity of the study amidst a novel condition, perceived stigma and discrimination, perceived invasion of privacy, discomfort with the testing procedures, and suboptimal financial reimbursements.

CONCLUSION

Effective publicity and outreach strategies have the potential to decrease refusal rates in study participation, especially if a condition is novel. Studies on infectious diseases should address stigma and discrimination to promote participation and ensure participant safety.

Brief Telephonic Motivational Interviewing for People Living with HIV with Follow-up Problems

Motivational interviewing (MI)-based interventions can be effective for people living with HIV (PLWHIV) with medical follow-up problems. This study aimed to assess the stage of motivation to attend medical appointments of PLWHIV with medical follow-up problems and to evaluate a single telephone session MI intervention directed to engage them in care. The change in stage was evaluated before and after the intervention, and attending medical appointments was monitored for six months. Thirty-nine PLWHIV participated; 51.3% were in precontemplation/contemplation and 49.7% in preparation/action stage. Most (excluding those in the action stage from the beginning) (n = 22, 71.0%) advanced to another stage after the intervention (z = - 4.235, p < .001), and most did not miss the following appointments. Brief and remote MI interventions could be useful in low-resource settings, especially for those in the early stages of change, to explore motivations related with missing medical appointments.

Informing evidence-based medicine for opioid use disorder using pharmacoeconomic studies

INTRODUCTION

The health and economic consequences of inadequately treated opioid use disorder (OUD) are substantial. Healthcare systems in the United States (US) and other countries are facing a growing healthcare crisis due to opioids. Although effective medications for OUD exist, relying solely on clinical information is insufficient for addressing the opioid crisis.

AREAS COVERED

In this review, the role of pharmacoeconomic studies in informing evidence-based medication treatment for OUD is discussed, with a particular emphasis on the US healthcare system, where the economic burden is significantly higher than the global average. The scope/objective of pharmacoeconomics as a distinct scientific research program is briefly defined, followed by a discussion of existing evidence informed by data from systematic reviews, in addition to a convenience sample of recently published pharmacoeconomic studies and protocols. The review also explores the need for methodological advancements in the field.

EXPERT OPINION

Despite the potential of pharmacoeconomic research in shaping evidence-based medicine for OUD, significant challenges limiting its real-world application remain. How to address these challenges are explored, including how to combine cost-effectiveness and budget impact analyses to address the needs of the healthcare system as a whole and specific stakeholders interested in adopting new OUD treatment strategies.

Virtual focus groups among individuals with use disorders: assessing feasibility and acceptability in an underserved clinical population

Objective

There are substantial barriers to conducting research among individuals with stigmatized and complicated health conditions like substance use disorders. These barriers slow progress when developing, refining, and assessing interventions to better treat underserved populations. Virtual focus groups are an innovative method for collecting data from individuals via a discreet and accessible platform which can inform novel as well as existing treatment approaches. This article reports on the feasibility and acceptability of virtual focus groups as a mechanism to recruit and engage geographically and demographically diverse samples of participants with substance use disorders that are otherwise logistically difficult to assess.

Method

Participants were assessed for eligibility for a virtual focus group study based on demographic features, drug use history, and psychiatric history via a remote, interview-based screening. Focus groups were completed anonymously without video or name-sharing. Discussion contributions, quantified with number of times speaking and total number of words spoken, were compared across gender, and treatment status. Participants provided quantitative and qualitative feedback on the focus group experience in a follow-up survey.

Results

Focus groups (N=26) based in geographical areas throughout the United States were conducted with 88 individuals with opioid use disorder or stimulant use disorder. Discussion contributions were comparable between genders and among individuals in treatment versus those seeking treatment. A follow-up survey (n=50, 57% of focus group participants) reflected high levels of enjoyment, comfort, and honesty during focus group discussions.

Discussion

Findings suggest virtual focus groups can be an effective and efficient tool for substance use research.

Uncovering key clinical trial features influencing recruitment

Background

Randomized clinical trials (RCT) are the foundation for medical advances, but participant recruitment remains a persistent barrier to their success. This retrospective data analysis aims to (1) identify clinical trial features associated with successful participant recruitment measured by accrual percentage and (2) compare the characteristics of the RCTs by assessing the most and least successful recruitment, which are indicated by varying thresholds of accrual percentage such as ≥ 90% vs ≤ 10%, ≥ 80% vs ≤ 20%, and ≥ 70% vs ≤ 30%.

Methods

Data from the internal research registry at Columbia University Irving Medical Center and Aggregated Analysis of ClinicalTrials.gov were collected for 393 randomized interventional treatment studies closed to further enrollment. We compared two regularized linear regression and six tree-based machine learning models for accrual percentage (i.e., reported accrual to date divided by the target accrual) prediction. The outperforming model and Tree SHapley Additive exPlanations were used for feature importance analysis for participant recruitment. The identified features were compared between the two subgroups.

Results

CatBoost regressor outperformed the others. Key features positively associated with recruitment success, as measured by accrual percentage, include government funding and compensation. Meanwhile, cancer research and non-conventional recruitment methods (e.g., websites) are negatively associated with recruitment success. Statistically significant subgroup differences (corrected p-value < .05) were found in 15 of the top 30 most important features.

Conclusion

This multi-source retrospective study highlighted key features influencing RCT participant recruitment, offering actionable steps for improvement, including flexible recruitment infrastructure and appropriate participant compensation.

Addressing stigma within the dissemination of research products to improve quality of care for pregnant and parenting people affected by substance use disorder

Substance use disorders are a common and treatable condition among pregnant and parenting people. Social, self, and structural stigma experienced by this group represent a barrier to harm reduction, treatment utilization, and quality of care. We examine features of research dissemination that may generate or uphold stigmatization at every level for pregnant and parenting individuals affected by substance use disorder and their children. We explore stigma reduction practices within the research community that can increase uptake of evidence-based treatment programs and prevent potential harm related to substance use in pregnant and parenting people. The strategies we propose include: (1) address researcher stereotypes, prejudice, and misconceptions about pregnant and parenting people with substance use disorder; (2) engage in interdisciplinary and transdisciplinary collaborations that engage with researchers who have lived experience in substance use; (3) use community-based approaches and engage community partners, (4) address stigmatizing language in science communication; (5) provide contextualizing information about the social and environmental factors that influence substance use among pregnant and parenting people; and (6) advocate for stigma-reducing policies in research articles and other scholarly products.

The process and challenges of language translation and cultural adaptation of study instruments: a case study from the NIDA CTN CHOICES-2 trial

BACKGROUND

As the U.S. grows more diverse, researchers decide how to include non-English speakers. Budget limitations may not allow for translation of all instruments. Study teams must determine which instruments must receive certified translations. This paper describes the procedures utilized in one U.S.-based, multi-site clinical trial to decide which study instruments should undergo certified translation and discusses dialect review procedures.

METHODS

The team determined which instruments (n = 31) would be translated using a qualitative evaluation to determine the need to obtain a Spanish-language certified translation: 1) "Could the meaning of these questions change (and potentially elicit a different response) if the translations were not consistent?" and 2) "Is it acceptable to have potential inconsistencies in these data?" Instruments for which question 1 was "yes" and question 2 was "no" (e.g., eligibility, outcomes, safety) were marked for certified translation. A dialect committee reviewed all translated patient-reported outcome measures to ensure that the translations had accounted for different meanings of words based on respondents' countries or regions of origin and recommended changes where necessary.

RESULTS

Fourteen interview-based instruments underwent certified forward-only translation into U.S. Spanish. The remaining 2 interview-based instruments were translated via real-time conversation with participants by bilingual staff. Six forms were administrative and not translated. Five out of 9 professionally translated patient-reported outcome measures were amended to better reflect relevant dialects.

CONCLUSIONS

In the absence of specific guidance, it is feasible for study team members to 1) determine which instruments should undergo certified translation and 2) incorporate dialect into translations.

Risk of Experiencing an Overdose Event for Patients Undergoing Treatment With Medication for Opioid Use Disorder

OBJECTIVE

Overdose risk during a course of treatment with medication for opioid use disorder (MOUD) has not been clearly delineated. The authors sought to address this gap by leveraging a new data set from three large pragmatic clinical trials of MOUD.

METHODS

Adverse event logs, including overdose events, from the three trials (N=2,199) were harmonized, and the overall risk of having an overdose event in the 24 weeks after randomization was compared for each study arm (one methadone, one naltrexone, and three buprenorphine groups), using survival analysis with time-dependent Cox proportional hazard models.

RESULTS

By week 24, 39 participants had ≥1 overdose event. The observed frequency of having an overdose event was 15 (5.30%) among 283 patients assigned to naltrexone, eight (1.51%) among 529 patients assigned to methadone, and 16 (1.15%) among 1,387 patients assigned to buprenorphine. Notably, 27.9% of patients assigned to extended-release naltrexone never initiated the medication, and their overdose rate was 8.9% (7/79), compared with 3.9% (8/204) among those who initiated naltrexone. Controlling for sociodemographic and time-varying medication adherence variables and baseline substance use, a proportional hazard model did not show a significant effect of naltrexone assignment. Significantly higher probabilities of experiencing an overdose event were observed among patients with baseline benzodiazepine use (hazard ratio=3.36, 95% CI=1.76, 6.42) and those who either were never inducted on their assigned study medication (hazard ratio=6.64, 95% CI=2.12, 19.54) or stopped their medication after initial induction (hazard ratio=4.04, 95% CI=1.54, 10.65).

CONCLUSIONS

Among patients with opioid use disorder seeking medication treatment, the risk of overdose events over the next 24 weeks is elevated among those who fail to initiate or discontinue medication and those who report benzodiazepine use at baseline.

Using Semistructured Telephone Interviews to Collect Qualitative Data From People With HIV Who Are Not in Medical Care: Implementation Study

BACKGROUND

The Medical Monitoring Qualitative (MMP-Qual) Project was designed to collect qualitative data from people with HIV not engaged in medical care that would complement quantitative data collected by the Medical Monitoring Project (MMP)-a national surveillance system-and inform the MMP's recruitment and data collection methods.

OBJECTIVE

Our objectives were to describe the methodology of this project, reflect on the challenges and lessons learned from conducting qualitative telephone interviews at a national level, and describe how we used and plan to use the qualitative data to evaluate our recruitment procedures and quantitative data collection instrument as well as knowledge of HIV care engagement.

METHODS

We used stratified purposive sampling to identify and recruit participants who had participated in the structured MMP interview into the MMP-Qual Project. To be eligible, participants must have had an HIV diagnosis, be aged ≥18 years, have lived in an MMP jurisdiction, and have not been engaged in HIV medical care. From August 1, 2018, to May 31, 2019, we conducted semistructured telephone interviews with 36 people with HIV across the United States about several topics (eg, facilitators and barriers to care and experience with surveys). Four trained interviewers conducted semistructured 60-minute telephone interviews with 36 participants. Data collection lasted from August 1, 2018, to May 31, 2019.

RESULTS

From 2018 to 2019, 113 people were eligible to participate in the MMP-Qual Project. Of the people recruited, 28% (22/79) refused to participate. Of those who agreed to participate, 63% (36/57) were interviewed, and 37% (21/57) were no-shows. Of the 34 participants for whom we had complete data, 15 (44%) were aged ≥50 years, 26 (76%) identified as male, 22 (65%) were Black or African American, and 12 (35%) lived in the Southern United States.

CONCLUSIONS

We learned that it is possible to obtain rich qualitative data from people with HIV who are not in care via telephone interviews and that this mode might be conducive to talking about sensitive topics. We also learned the importance of flexibility, communication, and coordination because we relied on health department staff to perform recruitment and had difficulty implementing our original sampling strategy. We hope that other projects will learn from our experience conducting qualitative telephone interviews with people with HIV on a national level.

Patient evaluation of a smartphone application for telehealth care of opioid use disorder

Background

People with opioid use disorder (OUD) face barriers to entering and remaining in life-saving treatment (e.g., stigma, detrimental interactions with health care, and privacy concerns). Telehealth and related technology can reduce barriers to entering and staying in care. Patient feedback is critical to the development of these newer treatment approaches to ensure they are usable and do not inadvertently recreate treatment barriers.

Purpose

Evaluate the perceived usability of existing and planned features of a mobile application (app) that facilitates delivery of OUD treatment via telehealth.

Methods

People with current or prior experience with OUD treatment were eligible for the study. Participants (n = 31; 55% women) provided feedback on an interactive prototype demonstration via individual qualitative interviews and completed a quantitative survey on the app’s perceived usability. Descriptive statistics summarized the usability survey. We analyzed qualitative interview transcripts to elicit common themes.

Results

Participants were primarily white (77%) with a mean age of 42.2 years (range 22–69). Participants rated the six major features of the current app as helpful (median response 5 out of 5) and appreciated the flexibility of conducting a visit from a place of their choosing. Participants regarded the five proposed components of the app, such as daily affirmations and medication treatment-related reminders (e.g., pick up medication at pharmacy, medication schedule), as useful features with medians 5 out of 5, and reported they would recommend the app to others for OUD care. Participant qualitative interviews provided additional information on perceived usability of existing and proposed app features.

Conclusion

Our study suggests that an appealing, easy-to-use app—with tools and features that effectively support care—could circumvent existing barriers and foster sustained recovery.

A pilot study of a mixed-method approach to design an ED-based peer mHealth referral tool for HIV/HCV and opioid overdose prevention services

BACKGROUND

The intersecting epidemics of opioid misuse, injection drug use, and HIV/HCV have resulted in record overdose deaths and sustained high levels of HIV/HCV transmissions. Literature on social networks suggests opportunities to connect people who use drugs (PWUD) and their peers to HIV/HCV and opioid overdose prevention services. However, little evidence exists on how to design such peer referral interventions in emergency department (ED) settings.

METHODS

A mixed-method study was conducted to assess the feasibility of an mHealth-facilitated 'patient to peer social network referral program' for PWUD. In-depth interviews (IDIs) and quantitative surveys were conducted with urban ED patients (n = 15), along with 3 focus group discussions (FGDs) (n = 19).

RESULTS

Overall, 34 participants were enrolled (71 % males, 53 % Black). 13/15 IDI participants reported a history of opioid overdose; all had witnessed overdose events; all received HIV/HCV testing. From survey responses, most would invite their peers for HIV/HCV testing and naloxone training; and anticipated peers to accept referrals (HIV: 60 %, HCV: 73 %, naloxone: 93 %). Qualitative data showed PWUD shared health-related information with each other but preferred word of mouth rather than text messages. Participants used smartphones regularly and suggested using Internet advertising for prevention services. Participants expressed enthusiasm for ED-based peer mHealth referral platform to prevention services, as well as referring their peers to proposed services, with monetary incentives.

CONCLUSION

ED-based peer referral intervention to HIV/HCV testing and naloxone training was viewed favorably by PWUD. Frequent smartphone use among PWUD suggests that the medium could be a promising mode for peer referral.

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.

Recruitment into a Clinical Trial of People Living with Uncontrolled HIV Infection Who Inject Drugs: a Site Case Report from the CTN 67 CHOICES Study

CHOICES was an open-label, randomized, comparative effectiveness trial of office-based extended-release naltrexone versus treatment as usual in people with untreated opioid use disorder and HIV. This study explored facilitators to recruitment in Miami, a successful recruiting site in the national trial. The mixed-methods study included quantitative surveys of randomized participants, medical record abstraction, and qualitative interviews with study staff. Miami recruited 47 (40.5%) of 116 randomized participants in the six-site national trial. In-depth interviews of study staff (n = 6) revealed that Miami had a recruitment approach consisting of street level outreach and a close relationship with the local syringe services program (SSP). Partnership with a local SSP provided access to people living with HIV who inject drugs in Miami. SSPs' fundamental trust within the community of people who inject drugs can be leveraged in studies aiming to improve health outcomes in this underserved and high-priority population.

Provider perceptions of medication for opioid used disorder (MOUD): A qualitative study in communities with high opioid overdose death rates

BACKGROUND

Medication for Opioid Use Disorder (MOUD) has been shown to be a safe, cost-effective intervention that successfully lowers risk of opioid overdose. However, access to and use of MOUD has been limited. Our objective was to explore attitudes, opinions, and beliefs regarding MOUD among healthcare and social service providers in a community highly impacted by the opioid overdose epidemic.

METHODS

As part of a larger ethnographic study examining neighborhoods in Allegheny County, PA, with the highest opioid overdose death rates, semi-structured qualitative in-person and telephone interviews were conducted with forty-five providers treating persons with opioid use disorders in these communities. An open coding approach was used to code interview transcripts followed by thematic analysis.

RESULTS

Three major themes were identified related to MOUD from the perspectives of our provider participants. Within a variety of health and substance use service roles and settings, provider reflections revealed: (1) different opinions about MOUD as a transition to abstinence or as a long-term treatment; (2) perceived lack of uniformity and dissemination of accurate information of MOUD care, permitting differences in care, and (3) observed barriers to entry and navigation of MOUD, including referrals as a "word-of-mouth insider system" and challenges of getting patients MOUD services when they need it.

CONCLUSIONS

Even in communities hard hit by the opioid overdose epidemic, healthcare providers' disagreement about the standard of care for MOUD can be a relevant obstacle. These insights can inform efforts to improve MOUD treatment and access for people with opioid use disorders.

Promoting inclusion in clinical trials-a rapid review of the literature and recommendations for action

Background

Without inclusion of diverse research participants, it is challenging to understand how study findings will translate into the real world. Despite this, a lack of inclusion of those from under-served groups in research is a prevailing problem due to multi-faceted barriers acting at multiple levels. Therefore, we rapidly reviewed international published literature, in relation to clinical trials, on barriers relating to inclusion, and evidence of approaches that are effective in overcoming these.

Methods

A rapid literature review was conducted searching PubMed for peer-reviewed articles that discussed barriers to inclusion or strategies to improve inclusion in clinical trial research published between 2010 and 2021. Grey literature articles were excluded.

Results

Seventy-two eligible articles were included. The main barriers identified were language and communication, lack of trust, access to trials, eligibility criteria, attitudes and beliefs, lack of knowledge around clinical trials, and logistical and practical issues. In relation to evidence-based strategies and enablers, two key themes arose: [1] a multi-faceted approach is essential [2]; no single strategy was universally effective either within or between trials. The key evidence-based strategies identified were cultural competency training, community partnerships, personalised approach, multilingual materials and staff, communication-specific strategies, increasing understanding and trust, and tackling logistical barriers.

Conclusions

Many of the barriers relating to inclusion are the same as those that impact trial design and healthcare delivery generally. However, the presentation of these barriers among different under-served groups may be unique to each population’s particular circumstances, background, and needs. Based on the literature, we make 15 recommendations that, if implemented, may help improve inclusion within clinical trials and clinical research more generally. The three main recommendations include improving cultural competency and sensitivity of all clinical trial staff through training and ongoing personal development, the need to establish a diverse community advisory panel for ongoing input into the research process, and increasing recruitment of staff from under-served groups. Implementation of these recommendations may help improve representation of under-served groups in clinical trials which would improve the external validity of associated findings.

Design, analysis, and reporting of pilot studies in HIV: a systematic review and methodological study

Background

Pilot studies are essential in determining if a larger study is feasible. This is especially true when targeting populations that experience stigma and may be difficult to include in research, such as people with HIV. We sought to describe how pilot studies have been used to inform HIV clinical trials.

Methods

We conducted a methodological study of pilot studies of interventions in people living with HIV published until November 25, 2020, using Medline, Embase, and Cochrane Controlled Register of Trials (CENTRAL). We extracted data on their nomenclature, primary objective, use of progression criteria, sample size, use of qualitative methods, and other contextual information (region, income, level, type of intervention, study design).

Results

Our search retrieved 10,597 studies, of which 248 were eligible. The number of pilot studies increased steadily over time. We found that 179 studies (72.2%) used the terms “pilot” or “feasibility” in their title, 65.3% tested feasibility as a primary objective, only 2% used progression criteria, 23.9% provided a sample size estimation and only 30.2% used qualitative methods.

Conclusions

Pilot studies are increasingly being used to inform HIV research. However, the titles and objectives are not always consistent with piloting. The design and reporting of pilot studies in HIV could be improved.

Perspectives on extended-release naltrexone induction among patients living with HIV and opioid use disorder: a qualitative analysis

BACKGROUND

The CHOICES study randomized participants with HIV and opioid use disorder (OUD) to HIV clinic-based extended-release naltrexone (XR-NTX), which requires complete cessation of opioid use, versus treatment-as-usual (i.e., buprenorphine, methadone). Study participants randomized to XR-NTX were interviewed to assess their experiences with successful and unsuccessful XR-NTX induction.

METHODS

Semi-structured qualitative interviews were completed with a convenience sample of study participants with HIV and OUD (n = 37) randomized to XR-NTX in five HIV clinics between 2018 and 2019. All participants approached agreed to be interviewed. Interviews were digitally recorded, professionally transcribed, and analyzed using thematic analysis.

RESULTS

Participants included women (43%), African Americans (62%) and Hispanics (16%), between 27 to 69 years of age. Individuals who completed XR-NTX induction (n = 20) reported experiencing (1) readiness for change, (2) a supportive environment during withdrawal including comfort medications, and (3) caring interactions with staff. Four contrasting themes emerged among participants (n = 17) who did not complete induction: (1) concern and anxiety about withdrawal including past negative experiences, (2) ambivalence about or reluctance to stop opioids, (3) concerns about XR-NTX effects, and (4) preferences for other medications.

CONCLUSIONS

The results highlight opportunities to improve initiation of XR-NTX in high-need groups. Addressing expectations regarding induction may enhance XR-NTX initiation rates.

Coordinating Systems of Care for HIV and Opioid Use Disorder: A Systematic Review of Enablers and Barriers to Integrated Service Access, and Systems and Tools Required for Implementation

Individuals who have HIV who also use drugs experience increased age-matched morbidity and mortality in comparison with those with HIV who do not use drugs. A systematic review was conducted to describe models of integrated HIV and opioid use disorder (OUD) services, enablers of and barriers to integrated service access, and the coordinated systems and tools at the state and service delivery levels required for implementation. Database searches yielded 235 candidate articles, of which 22 studies met the inclusion criteria. Analysis found that integrated programs operated with minimal coordinated policy and systems guidance at the state level. Service delivery systems and tools used for integration, including use of integrated protocols, risk assessment tools, case management tools, and referral systems, were similar across integration models. Concerted efforts to coordinate state-level systems and develop supportive policies, guidelines, and standardized tools may facilitate integration at the service delivery level.

Opioid use disorder treatment for people experiencing homelessness: A scoping review

BACKGROUND

The opioid-related overdose epidemic remains a persistent public health problem in the United States and has been accelerated by the 2019 coronavirus disease pandemic. Existing, evidence-based treatment options for opioid use disorder (OUD) are broadly underutilized, particularly by people experiencing homelessness (PEH). PEH are also more likely to misuse and overdose on opioids. To better understand current gaps and disparities in OUD treatment experienced by PEH and efforts to address them, we synthesized the literature reporting on the intersection of housing status and OUD treatment.

METHODS

We conducted a scoping review of the literature from the electronic databases MEDLINE, Embase, PsycINFO, and Web of Science Core Collection. We included studies describing treatment-related outcomes specific to PEH and articles assessing OUD treatment interventions tailored to this population. Relevant findings were compiled via thematic analysis and narratively synthesized.

RESULTS

60 articles met our inclusion criteria, including 43 descriptive and 17 intervention-focused studies. These studies demonstrated that PEH experience more barriers to OUD treatment than their housed counterparts and access inpatient and detoxification treatment more commonly than pharmacotherapy. However, the reviewed literature indicated that PEH have similar outcomes once engaged in pharmacotherapy. Efficacious interventions for PEH were low-barrier and targeted, with housing interventions also demonstrating benefit.

CONCLUSIONS

PEH have diminished access to evidence-based OUD treatment, particularly medications, and require targeted approaches to improve engagement and retention. To mitigate the disproportionate opioid-related morbidity and mortality PEH experience, innovative, flexible, and interdisciplinary OUD treatment models are necessary, with housing support playing an important role.

Linking criminal justice-involved individuals to HIV, Hepatitis C, and opioid use disorder prevention and treatment services upon release to the community: Progress, gaps, and future directions

Improving HIV and Hepatitis C Virus (HCV) management among people involved in the criminal justice (CJ) system who use drugs, in particular those with opioid use disorder (OUD), requires effective approaches to screening, linkage, and adherence to integrated prevention and treatment services across correctional and community agencies and providers. This manuscript reviews the literature to explore gaps in HIV, Hepatitis C, and OUD prevention, treatment, and delivery cascades of care for persons involved in the CJ system. Specifically, we compare two models of linkage to prevention and treatment services: Peer/Patient Navigation (PN) wherein the PN links CJ-involved individuals to community-based infectious disease (ID) and substance use prevention and treatment services, and Mobile Health Units (MHU) wherein individuals are linked to a MHU within their community that provides integrated ID and substance use prevention and treatment services. The most notable finding is a gap in the literature, with few to no comparisons of models linking individuals recently released from the CJ system to integrated HIV, Hepatitis C, and OUD prevention and treatment and other harm reduction services. Further, few published studies address the geographical distinctions that affect service implementation and their effects on these substance use, ID and harm reduction care cascades. This manuscript makes specific recommendations to fill this gap through a detailed evaluation of PN and MHU linkage models to co-located and integrated HIV, Hepatitis C, and OUD prevention and treatment services across different communities within the U.S.

Transporting to treatment: Evaluating the effectiveness of a mobile engagement unit

BACKGROUND

Substance use treatment providers have increasingly developed novel engagement and low-threshold treatment services (such as mobile treatment units) to meet the needs of people with opioid use disorder (OUD). Use of these service models has outpaced the research on their effectiveness. The current study examines the effectiveness of a mobile engagement unit in connecting individuals with OUD to a treatment program.

METHODS

This retrospective cohort study included 468 Medicaid-enrolled individuals served through a managed care behavioral health system. Analyses used administrative data from 2018 to 2019 to compare the characteristics and service use of individuals transported to an intake appointment by a mobile engagement unit with individuals who arrived through typical referral routes such as walk-in, other providers, and court order. The authors employed a difference-in-differences analysis to adjust for prior service history. The outcomes of interest were any utilization of substance use treatment services.

RESULTS

The groups were virtually identical in age and gender, prior to matching, except for race where there was a lower proportion of Black individuals (17% versus 44%) and lower pre-service utilization of outpatient and methadone services by the mobile group. Following intake, mobile participants used significantly more outpatient substance use treatment services (23 percentage point relative increase) and methadone maintenance (32 percentage point relative increase) than the comparison group.

CONCLUSIONS

The results of this study suggest that mobile engagement units designed to identify and serve individuals with OUD in the community hold promise for reaching underserved high-risk populations and reduce barriers to treatment entry and recovery.

Factors Influencing Successful Recruitment of Racial and Ethnic Minority Patients for an Observational HIV Cohort Study in Washington, DC

The process of recruiting racial and ethnic minority persons living with HIV (PLWH) is important for research studies to ensure inclusivity of underrepresented groups. To understand factors associated with recruitment of minority PLWH, this study examined the recruitment process of PLWH for an observational study of their routine medical care at 14 clinics in Washington, DC. Research assistant (RA) recruiters were interviewed to assess their consenting processes and strategies. Data were collected on clinic services, patient demographics, and recruitment logs of patient approaches for obtaining informed consent resulting in agreement or refusal. A median of 96% of eligible patients was approached to obtain consent, yielding a median consent rate of 78% across all sites. A total of 8438 patients consented and 1326 refused study participation. Clinical sites with more comprehensive services had higher consent rates. black/African American and Hispanic/Latinx PLWH consented or refused study participation in similar proportions, while significantly more white patients enrolled than refused. More men, compared with women, enrolled than refused study participation. The most frequent reasons for refusing study participation were the lack of interest in research (33.2%) and no specific reason provided (28%). RAs identified that effective recruitment strategies used culturally sensitive approaches, built rapport with patients, and obtained provider support for the study. Recruitment strategies that are gender sensitive to address the disparity of underrepresentation of women, address perceived barriers, and examine clinic-specific services are needed to maximize research participation for minority PLWH to improve prevention and health outcomes.

Opioid Use Disorders in People Living with HIV/AIDS: A Review of Implications for Patient Outcomes, Drug Interactions, and Neurocognitive Disorders

The opioid epidemic has had a significant, negative impact in the United States, and people living with HIV/AIDS (PLWHA) represent a vulnerable sub-population that is at risk for negative sequela from prolonged opioid use or opioid use disorder (OUD). PLWHA are known to suffer from HIV-related pain and are commonly treated with opioids, leading to subsequent addictive disorders. PLWHA and OUD are at an increased risk for attrition in the HIV care continuum, including suboptimal HIV laboratory testing, delayed entry into HIV care, and initiation or adherence to antiretroviral therapy. Barriers to OUD treatment, such as medication-assisted therapy, are also apparent for PLWHA with OUD, particularly those living in rural areas. Additionally, PLWHA and OUD are at a high risk for serious drug–drug interactions through antiretroviral-opioid metabolic pathway-related inhibition/induction, or via the human ether-a-go-go-related gene potassium ion channel pathways. HIV-associated neurocognitive disorders can also be potentiated by the off-target inflammatory effects of opioid use. PLWHA and OUD might require more intensive, individualized protocols to sustain treatment for the underlying opioid addiction, as well as to provide proactive social support to aid in improving patient outcomes. Advancements in the understanding and management of PLWHA and OUD are needed to improve patient care. This review describes the effects of prescription and non-prescription opioid use in PLWHA.
