Application of the multiphase optimisation strategy (MOST) to optimise HIV prevention targeting people on medication for opioid use disorder (MOUD) who have cognitive dysfunction: protocol for a MOST study.

INTRODUCTION: People who inject drugs (PWID) have remained a contributor to the consistent HIV incidence rates in the US for decades. Pre-exposure prophylaxis (PrEP) is a promising biomedical intervention for HIV prevention among individuals at risk for HIV infection, including PWID. However, PWID report the lowest rates of PrEP uptake and adherence among at-risk groups. Tailored HIV prevention interventions must include strategies that compensate for cognitive dysfunction among PWID. METHODS AND ANALYSIS: Using the multiphase optimisation strategy, we will be conducting a 16-condition factorial experiment to investigate the effects of four different accommodation strategy components to compensate for cognitive dysfunction among 256 PWID on medication for opioid use disorder. This innovative approach will inform optimisation of a highly effective intervention to enhance PWID's ability to process and utilise HIV prevention content to improve PrEP adherence and HIV risk reduction in a drug treatment setting. ETHICS AND DISSEMINATION: The institutional review board at the University of Connecticut approved this protocol (H22-0122) with an institutional reliance agreement with APT Foundation Inc. All participants are required to sign an informed consent form prior to engaging in any study protocols. The results of this study will be disseminated on national and international platforms through presentations at major conferences and journals. TRIAL REGISTRATION NUMBER: NCT05669534.

Latent profile analysis of data from the brief inventory of neurocognitive impairment (BINI) to develop neuro-cognitive profiles among opioid-dependent patients in drug treatment.

BACKGROUND: Neurocognitive dysfunction is common among individuals with opioid use disorders (OUD) and can impede a range of treatment outcomes. We developed the 57-item Brief Inventory of Neuro-cognitive Impairment (BINI) to help detect and monitor neurocognitive dysfunction in the context of drug treatment settings. To date, no study has examined the possible presence of BINI subgroups among OUD patients, which could enhance our ability to tailor intervention strategies to meet individual treatment needs. The purpose of this study was to conduct a latent profile analysis to identify BINI subgroups that differ in terms of their reported and objective neurocognitive dysfunction. We hypothesized that subgroups would emerge, suggesting the potential benefit of implementing tailored strategies for optimal treatment outcomes. METHODS: Latent profile analyses included data from opioid-dependent patients (N = 177) enrolled in a methadone maintenance treatment program between July 2018 and October 2019. RESULTS: We found three profiles of self-reported neurocognitive symptoms, including those with 1) minimal concerns 2) moderate concerns, and 3) many concerns across multiple domains. CONCLUSIONS: If these results are confirmed, the BINI may be used to rapidly identify persons who require specific accommodation strategies to improve their drug treatment outcomes.

Condomless sex under the influence differs by class rank in college students.

OBJECTIVE: College students, particularly first-year students, are at risk for alcohol misuse and alcohol-related consequences (e.g., condomless sex). Our objective was to determine if first- and second-year students were more or less likely to report any act of condomless sex under the influence of alcohol than third- and fourth-year students. PARTICIPANTS: Participants (N = 447) were undergraduate students recruited from a private institution in Massachusetts. METHODS: Logistic regression models were used to analyze differences in reported acts of condomless sex under the influence of alcohol in the past 30 days, by class rank. RESULTS: First- and second-year students had lower odds (OR 0.40, 95% CI: 0.252-0.648) of reporting condomless sex under the influence of alcohol than third- and fourth-year students. CONCLUSIONS: Implications from these results can contribute to understanding sexually transmitted infections in the college population.

Integrating Cognitive Dysfunction Accommodation Strategies Into Behavioral Interventions for Persons on Medication for Opioid Use Disorder.

BACKGROUND: Cognitive dysfunction is disproportionately prevalent among persons with opioid use disorder (OUD). Specific domains of cognitive dysfunction (attention, executive functioning, memory, and information processing) may significantly impede treatment outcomes among patients on medication for OUD (MOUD). This limits patient's ability to learn, retain, and apply information conveyed in behavioral intervention sessions. Evidence-based accommodation strategies have been integrated into behavioral interventions for other patient populations with similar cognitive profiles as persons with OUD; however, the feasibility and efficacy of these strategies have not yet been tested among patients on MOUD in a drug treatment setting. METHODS: We conducted a series of focus groups with 25 key informants (10 drug treatment providers and 15 patients on MOUD) in a drug treatment program in New Haven, CT. Using an inductive approach, we examined how cognitive dysfunction impedes participant's ability to retain, recall, and utilize HIV prevention information in the context of drug treatment. RESULTS: Two main themes capture the overall responses of the key informants: (1) cognitive dysfunction issues and (2) accommodation strategy suggestions. Subthemes of accommodation strategies involved suggestions about particular evidence-based strategies that should be integrated into behavioral interventions for persons on MOUD. Specific accommodation strategies included: use of a written agenda, mindfulness meditation, multi-modal presentation of information, hands-on demonstrations, and a formal closure/summary of sessions. CONCLUSIONS: Accommodation strategies to compensate for cognitive dysfunction were endorsed by both treatment providers and patients on MOUD. These accommodation strategies have the potential to enhance the efficacy of behavioral interventions to reduce HIV transmission among persons on MOUD as well as addiction severity, and overdose.

Clinical and demographic differences in the willingness to use self-administered at-home COVID-19 testing measures among persons with opioid use disorder.

Background: COVID-19 is disproportionately affecting disadvantaged populations, including persons with opioid use disorder (OUD). Persons with OUD are at greater risk for direct (e.g., COVID-19 diagnosis, severe symptoms) and indirect consequences (relapse, overdose) of COVID-19. Given stay at home orders, at-home testing options may serve as a viable tool to curb the increase in COVID-19 transmission and adverse effects of COVID-19. Methods: From May to September 2020, we surveyed 110 persons in treatment for OUD about their willingness to use various self-administered at-home COVID-19 testing measures. Participants were stratified by age, gender, and racial-ethnic identity to observe differences in willingness to use COVID-19 tests. The three COVID-19 tests included a throat swab sample, a saliva-based sample, and a blood prick test. Results: A high willingness to use at-home COVID-19 tests was observed in patients in treatment for OUD. A greater proportion of females were willing to use a saliva-based test; greater proportions of White participants were willing to use a saliva based COVID-19 test compared to racial-ethnic minorities. Older aged participants (≥45 years old) reported greater rates of willingness to use a self-administered at home blood prick test for COVID-19. Conclusions: At-home testing measures for COVID-19 appear highly acceptable among people with OUD.

Pleasure and PrEP: A Systematic Review of Studies Examining Pleasure, Sexual Satisfaction, and PrEP.

Pre-exposure prophylaxis (PrEP) is an effective form of Human Immunodeficiency Virus (HIV) prevention for people at potential risk for exposure. Despite its demonstrated efficacy, PrEP uptake and adherence have been discouraging, especially among groups most vulnerable to HIV transmission. A primary message to persons who are at elevated risk for HIV has been to focus on risk reduction, sexual risk behaviors, and continued condom use, rarely capitalizing on the positive impact on sexuality, intimacy, and relationships that PrEP affords. This systematic review synthesizes the findings and themes from 16 quantitative, qualitative, and mixed methods studies examining PrEP motivations and outcomes focused on sexual satisfaction, sexual pleasure, sexual quality, and sexual intimacy. Significant themes emerged around PrEP as increasing emotional intimacy, closeness, and connectedness; PrEP as increasing sexual options and opportunities; PrEP as removing barriers to physical closeness and physical pleasure; and PrEP as reducing sexual anxiety and fears. It is argued that positive sexual pleasure motivations should be integrated into messaging to encourage PrEP uptake and adherence, as well as to destigmatize sexual pleasure and sexual activities of MSM.

Evidence of Potential Discriminatory HIV Pre-Exposure Prophylaxis (PrEP) Prescribing Practices for People Who Inject Drugs Among a Small Percentage of Providers in the U.S.

INTRODUCTION: A large percentage of people who inject drugs (PWID) are living with HIV. Yet, rates of HIV pre-exposure prophylaxis (PrEP) use among PWID remain low. Stigma surrounding substance use and PWID have been identified as potential barriers to PrEP. This study examined healthcare providers' concerns regarding PWID and willingness to prescribe PrEP to PWID. METHODS: An online, cross-sectional survey of a diverse group of healthcare providers in the 10 U.S. cities with the greatest HIV prevalence was conducted between July 2014 and May 2015. Participants responded to a patient vignette of a PWID and asked to indicate whether the patient would be a candidate for PrEP and why via free-response text. Descriptive statistics are reported using frequency measures. Bivariate analyses were conducted using chi-squared comparisons and logistical regression. RESULTS: Survey data from 480 providers were included in analyses. Of the 480 responses, 85.5% were classified as PrEP aware, while 14.2% were PrEP unaware. Additionally, 82.6% indicated the patient would be a good candidate for PrEP, 4.4% believed the patient was not a good candidate for PrEP, and 13% were unsure. Among those who were unsure or would not prescribe PrEP (n = 84), open-ended responses indicated lack of knowledge (42.9%), concern about adherence (27.4%), concern about cost (4.8%), and bias (7.1%) as the primary reasons. CONCLUSIONS: Although the majority of providers in this study did not demonstrate bias against PWID, our study found that limited PrEP knowledge and bias are barriers to PrEP prescription among PWID for some providers. Interventions are needed that increase PrEP awareness of CDC guidelines and reduce implicit bias among providers.

Cognitive profiles in persons with opioid use disorder enrolled in methadone treatment.

Cognitive impairment is common in persons with opioid use disorder and associated with poor treatment outcomes, including elevated risk for relapse. Much less is known about the underlying structure of these deficits and the possible presence of cognitive phenotypes. A total of 177 adults (average 42.2 years of age, 52.0% male, 65.5% Caucasian) enrolled in a methadone maintenance treatment program completed the NIH Toolbox as part of a larger project. Cluster analyses revealed a 2-cluster solution-persons with intact cognitive function in all domains (n = 93; Intact) and those with impairments on tests of attention and executive function (n = 83; Impaired). Follow-up analyses revealed that the Impaired group was slightly older, more likely to self-identify as a racial/ethnic minority, and less likely to report consuming alcohol four or more times per week. These findings suggest the existence of distinct cognitive profiles in persons with opioid use disorder and encourage further examination, particularly studies to examine the possible benefits of routine screening for cognitive impairment as part of substance use treatment.

Adapting behavioural interventions to compensate for cognitive dysfunction in persons with opioid use disorder.

Treatment for opioid use disorder (OUD) is often in the context of biobehavioural interventions, consisting of medication for OUD (for example, methadone and buprenorphine), which is accompanied by psychoeducation and/or behavioural therapies. Patients with OUD often display weaknesses in cognitive function that may impact the efficacy of such behavioural interventions. A review of the literature was conducted to: (1) describe common cognitive dysfunction profiles among patients with OUD, (2) outline intervention approaches for patients with OUD, (3) consider the cognitive demands that interventions place on patients with OUD and (4) identify potential accommodation strategies that may be used to optimise treatment outcomes. Cognitive profiles of patients with OUD often include weaknesses in executive function, attention, memory and information processing. Behavioural interventions require the patients' ability to learn, understand and remember information (placing specific cognitive demands on patients). Accommodation strategies are, therefore, needed for patients with challenges in one or more of these areas. Research on accommodation strategies for patients with OUD is very limited. We applied research from populations with similar cognitive profiles to form a comprehensive collection of potential strategies to compensate for cognitive dysfunction among patients with OUD. The cognitive profiles and accommodation strategies included in this review are intended to inform future intervention research aimed at improving outcomes among patients with OUD.

Differential impacts of COVID-19 across racial-ethnic identities in persons with opioid use disorder.

OBJECTIVE: The COVID-19 pandemic has exacerbated health disparities, particularly among at-risk people with opioid use disorder (OUD). We sought to characterize the direct and indirect impacts of COVID-19 on this group to understand how the pandemic has affected this group, this group's public health response to COVID-19, and whether there were differences by race/ethnicity. METHODS: This study recruited its sample from a drug treatment setting in the northeast region of the United States. We surveyed 110 individuals on methadone as treatment for OUD and assessed COVID-19-related impacts on their health behaviors and other indices of social, physical, and mental well-being, including sexual health behaviors, substance use, mental health status, health care access, income, and employment. RESULTS: Our findings highlight overall increases in depression, anxiety, loneliness, and frustration among the sample of people with OUD; the study also observed decreases in financial stability. Significant differences between groups indicated a greater financial burden among racial-ethnic minorities; this subgroup also reported greater direct adverse effects of COVID-19, including being more concerned about contracting COVID-19, not being able to get a COVID-19 test, and knowing someone who had died from COVID-19. A greater proportion of Whites indicated increases in alcohol consumption and non-prescription drug use than did racial-ethnic minorities. CONCLUSIONS: Treatment providers must be vigilant in managing direct and indirect outcomes of COVID-19 among people with OUD. Findings highlight the need to develop culturally competent, differentiated interventions in partnership with community-based organizations to meet the unique challenges that the COVID-19 pandemic presents for people in treatment for OUD.

Developing a cognitive dysfunction risk score for use with opioid-dependent persons in drug treatment.

BACKGROUND: Cognitive dysfunction is common in persons seeking medication for opioid use disorder (MOUD) and may hinder many addiction-related services. Brief but accurate screening measures are needed to efficiently assess cognitive dysfunction in these resource-limited settings. The study aimed to develop a brief predictive risk score tailored for use among patients in drug treatment. METHODS: The present study examined predictors of mild cognitive impairment (MCI), objectively assessed via the NIH Toolbox, among 173 patients receiving methadone as MOUD at an urban New England drug treatment facility. Predictors of MCI were identified in one subsample using demographic characteristics, medical chart data, and selected items from the Brief Inventory of Neuro-Cognitive Impairment (BINI). Predictors were cross-validated in a second subsample using logistic regression. Receiver operating curve (ROC) analyses determined an optimal cut-off score for detecting MCI. RESULTS: A cognitive dysfunction risk score (CDRS) was calculated from patient demographics (age 50+, non-White ethnicity, less than high school education), medical and substance use chart data (history of head injury, overdose, psychiatric diagnosis, past year polysubstance use), and selected self-report items (BINI). The CDRS discriminated acceptably well, with a ROC curve area of 70.6 %, and correctly identified 78 % of MCI cases (sensitivity = 87.5 %; specificity = 55.6 %). CONCLUSIONS: The CDRS identified patients with cognitive challenges at a level likely to impede treatment engagement and/or key outcomes. The CDRS may assist in efficiently identifying patients with cognitive dysfunction while requiring minimal training and resources. Larger validation studies are needed in other clinical settings.

The Impact of COVID-19 on Access to HIV Prevention Services Among Opioid-Dependent Individuals.

The COVID-19 pandemic has necessitated restrictive orders and programmatic changes that may be associated with disruptions in services, including those for opioid-dependent people who inject drugs (PWID). This study aims to assess the impact of COVID-19 pandemic on access to and utilization of various HIV prevention services among PWID with opioid use disorder (OUD). We interviewed 110 PWID enrolled in medication for opioid use disorder (MOUD) treatment (e.g., methadone) between May and October, 2020 to identify if this sample experienced changed in access to the following services due to the COVID-19 pandemic: (a) HIV or sexually transmitted infection (STI) testing, (b) pre-exposure prophylaxis (PrEP) services, (c) HIV counselor or doctor appointments, and (d) clean injection equipment. A majority of the sample reported that COVID-19 had not changed their access to HIV testing or access to STI testing. Almost half of the sample reported that getting an appointment with a doctor decreased due to COVID-19. Participants reported that access to a lab or blood testing, access to injection equipment, and sessions with a case manager or counselor decreased. One-fourth of the 32 participants who were taking PrEP before the onset of COVID-19 reported that they had trouble getting their PrEP prescription due to COVID-19, and some reported that they had difficulty getting the PrEP prescription filled at their pharmacy. Our results indicate that PWID did not experience reduced access to HIV or STI testing, but difficulties in obtaining appointments with HIV counselors or doctors and limited access to PrEP were presented. Innovative strategies are needed to reduce the adverse effects of COVID-19 on HIV prevention among PWID.

Engagement in Harm Reduction Strategies After Suspected Fentanyl Contamination Among Opioid-Dependent Individuals.

The evolving opioid epidemic in the United States has increased drug-related overdose rates exponentially (Centers for Disease Control and Prevention in Opioid overdose, 2020c, https://www.cdc.gov/drugoverdose/data/otherdrugs.html#:~:text=Polysubstance%20drug%20use%20occurs%20with,or%20other%20non%2Dopioid%20substances ). Fentanyl, a synthetic opioid, has recently fueled the epidemic, increasing overdose death rates (Centers for Disease Control and Prevention in Drug overdose deaths involving fentanyl, 2011-2016, 2019a, https://www.cdc.gov/nchs/data/nvsr/nvsr68/nvsr68_03-508.pdf ). Harm reduction strategies (drug checking, naloxone administration, etc.) are at the forefront of preventing opioid-related overdoses in high-risk populations (Kennedy et al. in Drug Alcohol Depend 185:248-252, 2018, https://doi.org/10.1016/j.drugalcdep.2017.12.026 ; Laing et al. in Int J Drug Policy 62:59-66, 2018, https://doi.org/10.1016/j.drugpo.2018.10.001 ). Little is known, however, about how people who inject drugs (PWID) may modify their drug use behaviors after suspected fentanyl contamination in their drugs. We conducted a cross-sectional survey among 105 opioid-dependent PWID enrolled in a methadone maintenance program. We assessed their willingness to engage in various harm reduction methods (i.e., slowing down drug use, not using drugs, carrying naloxone, using with someone who has naloxone) after suspected fentanyl contamination of their drugs. In a multivariable analysis, participants who were white, low-income, polysubstance users, and had previously experienced an overdose or had previously administered naloxone were more likely to report a willingness to engage in harm reduction measures. These findings provide an evidence-based understanding of PWID's engagement in harm reduction behaviors after suspecting potential fentanyl exposure as well as a basis for tailoring intervention strategies in the context of fentanyl-adulterated markets.

The Pre-exposure Prophylaxis (PrEP) Care Cascade in People Who Inject Drugs: A Systematic Review.

Injection drug use is a key risk factor for the transmission of HIV. Prevention strategies, such as the use of pre-exposure prophylaxis (PrEP), are effective at reducing the risk of HIV transmission in people who inject drugs (PWID). Following PRISMA guidelines, a literature search was conducted to identify the current state of the PrEP care cascade in PWID. Twenty-three articles were evaluated in this systematic review. A decline in engagement throughout the stages of the PrEP care cascade was found. High awareness and willingness to use PrEP was found, yet PrEP uptake was relatively low (0-3%). There is a lack of research on interventions to increase engagement of PrEP across all levels of the care cascade in PWID. Implications from the interventions that have been published provide insight into practice and public policy on efficacious strategies to reduce HIV incidence in PWID. Our findings suggest that more efforts are needed to identify and screen PWID for PrEP eligibility and to link and maintain them with appropriate PrEP care.
