BACKGROUND AND AIMS/OBJECTIVE:There are currently no brief quantitative assessments that capture the drug patterns of people who engage in use of more than one drug on the same day or simultaneously. The current study examined the retest reliability, acceptability and feasibility of a new quantitative assessment to measure polysubstance use. DESIGN/METHODS:A tool for assessing simultaneous and same-day polysubstance behaviors, the polysubstance assessment tool (PAT) was developed in interviewer-administered and electronic self-administered formats. Participants were allocated 1:1 to receive either version of the PAT and returned one to three days later to repeat the assessment. SETTING/METHODS:New York City, New York, USA. PARTICIPANTS/METHODS:Adults (18 + years, n = 115) who reported use of more than one drug per day in the last 30 days. MEASUREMENTS/METHODS:Test-retest reliability estimates for dichotomous items were assessed using Cohen's kappa, Gwet's Agreement Coefficient 1 (AC1) and percent agreement. Continuous items were assessed with two-way mixed effects intraclass correlations. Bivariate analyses examined acceptability using nine Likert-type survey questions. Feasibility was examined via time to completion. FINDINGS/RESULTS:Overall reliability was moderate to excellent [Gwet's AC1 range 0.70-0.96; intraclass correlation (ICC) range 0.62-0.88]. Reliability was higher for simultaneous polysubstance use (Gwet's AC1 = 0.90) as compared with same-day (Gwet's AC1 = 0.70). Acceptability was high, with no statistically significant difference between the self- and interviewer-administered versions of the tool. Median time to completion was 7 minutes, and was statistically significantly lower for the self-administered tool (median = 5 minutes) compared with the interviewer-administered version (median = 8 minutes) (P < 0.001). CONCLUSIONS:A new polysubstance assessment tool appears to have good reliability and can be considered by researchers seeking a quantitative measure of polysubstance use behaviors given its simplicity, high acceptability and quick completion time.

IMPORTANCE/UNASSIGNED:Emergency departments (EDs) serve patients at high risk for overdose. There is increasing interest in peer-delivered ED interventions for substance use but little rigorous research on their effectiveness. OBJECTIVE/UNASSIGNED:To examine the effectiveness of an initiative (Relay) operated by the New York City Health Department that dispatches trained peer wellness advocates (WAs) to support ED patients after a nonfatal opioid overdose. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This randomized clinical trial compared Relay and site-directed care (SDC) at 4 EDs in New York, New York. Adult patients presenting after opioid-involved overdose were enrolled from October 6, 2020, to June 30, 2022, with 12 months of outcome follow-up. Statistical analysis was performed from November 4, 2024, to May 6, 2025. INTERVENTION/UNASSIGNED:ED workers (generally physicians) called the Relay hotline for patients presenting after a suspected opioid-involved overdose. WAs met patients in the ED to provide peer support and brief overdose risk reduction education. WAs attempted to contact patients for 90 days to provide ongoing support, education, and referrals using a harm reduction framework. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Opioid-related adverse events (any opioid-involved overdose [fatal or nonfatal] or any other substance use-related ED visit) in the 12 months after enrollment were identified using health care administrative data plus self-report. RESULTS/UNASSIGNED:Among a total of 253 participants randomized, 127 were randomized to the Relay arm and 126 to the SDC arm. A total of 247 participants, 125 in the Relay arm and 122 in the SDC arm (190 [76.9%] men; 80 [32.4%] Black, 126 [51.0%] Hispanic or Latinx, 76 [30.8%] White, and 91 other race [36.8%]), were included in the intention-to-treat analyses. No statistically significant differences between arms were observed for the primary outcome (mean [SD] opioid-related adverse events, 3.29 [4.52] in the Relay arm and 4.10 [9.36] in the SDC arm; rate ratio, 1.02; 95% CI, 0.72-1.45; P = .90). By 12 months after enrollment, 24 participants (9.7%) had died (17 [70.8%] due to overdose). Relay participants reported high satisfaction with the ED intervention. CONCLUSIONS AND RELEVANCE/UNASSIGNED:This randomized clinical trial examining the impact of an ED peer navigator intervention on subsequent opioid-related adverse events did not find significant outcome differences for Relay vs SDC participants. These findings highlight the importance of intervening to save lives in this high-risk population and suggest potential refinements to future ED peer intervention research.

Black and Latine transgender/gender-expansive youth/emerging adults ages 13-24 years, experience disproportionate HIV risk, yet have the lowest PrEP uptake rates in the U.S. (< 8%). This study examines the effects of gender-minority stressors, gender affirmation, and heavy substance use on their PrEP outcomes using data from the CDC's 2018 START study (N = 423). We used structural equation modeling (Mplus v. 8.10) to examine factors related to their PrEP intentions using our newly developed conceptual model. The majority of participants were 18-24 (77.3%), transfemale (69.7%), Latine (63.1%), and reported heavy substance use behaviors (50.6%). Family rejection increased perceived stigma (b = 0.209, SE = 0.050, p < 0.001) and heavy substance use behaviors (b = 0.356, SE = 0.072, p < 0.001). Perceived stigma also increased heavy substance use behaviors (b = 0.084, SE = 0.041, p 0.041). Additionaly, heavy substance use decreased PrEP intentions (b = -0.160, SE = 0.049, p < 0.001), while gender affirmation increased PrEP intentions (b = 0.087, SE = 0.030, p < 0.004). When family rejection was present, for each 1-point increase in gender affirmation, the risk of heavy substance use was reduced by -0.197 (SE = 0.038; p < 0.001). This study identifies heavy substance use as a potential barrier to PrEP uptake among Black and Latine transgender and gender-expansive youth, given its significant negative association with PrEP intentions. Findings highlight the need for strategies to improve PrEP outcomes, underscoring the importance of operationalizing gender affirmation across settings, particularly amid family rejection and heavy substance use.

OBJECTIVE:This paper examines depression, post-traumatic stress disorder (PTSD), and comorbid depression/PTSD among Black and Latinx young and emerging adults (YEA) living with HIV. We incorporated a social-ecological framework to examine risk factors associated with mental health conditions, comparing foreign and US-born groups. METHODS:We used a hybrid recruitment strategy and surveyed 271 Black and Latinx YEA (ages 19-28 years) living with HIV in the Eastern USA. We used multivariable logistic regressions and hypothesized certain individual, interpersonal, community/societal risk factors would be positively associated with depression, PTSD, and comorbid depression/PTSD. RESULTS:Participants experienced elevated rates of depression (33.9%), PTSD (34.0%), and comorbid depression/PTSD (19.1%). Contrary to our hypothesis, US-born participants had significantly higher rates of mental health conditions compared to foreign-born participants. At the individual-level, foreign-born was associated with lower comorbid depression/PTSD [RRR 0.38 (95% CI 0.15, 0.97)], cisgender with lower comorbid depression/PTSD [RRR 0.42 (95% CI 0.18, 0.99)], greater number of Adverse Childhood Experiences with PTSD [OR 1.18 (95% CI 1.08, 1.29)], and comorbid depression/PTSD [RRR 1.28 (95% CI 1.12, 1.47)], while moderate/high substance use with depression [OR 2.30 (95% CI 1.01, 5.25)] and comorbid depression/PTSD [RRR 3.74 (95% CI 1.07, 13.03)]. At the interpersonal-level, lower social support was associated with higher depression [OR 0.99 (95% CI 0.97, 1.00)], PTSD [OR 0.98 (95% CI 0.97, 0.99)], and comorbid depression/PTSD [RRR 0.97 (95% CI 0.96, 0.99)]. At the community/societal-level, discrimination was associated with higher depression [OR 1.05 (95% CI 1.02, 1.08)] and comorbid depression/PTSD [RRR 1.07 (95% CI 1.02, 1.11)]. IMPLICATIONS/CONCLUSIONS:Understanding social-ecological risk factors associated with mental health conditions of Black and Latinx YEA living with HIV is important in determining potential avenues for targeted prevention and intervention to improve mental health.

BACKGROUND/UNASSIGNED:In 2021, NYC implemented overdose prevention center (OPC) services at two existing syringe exchange programs, allowing people to use pre-obtained drugs on-site. Although OPCs in Canada, Western Europe, and Australia have demonstrated their feasibility and benefits towards reducing overdose risk and drug-related harm, there is less data on how people who use drugs (PWUD) conceptualize the benefits and any potential drawbacks of using OPCs. METHODS/UNASSIGNED:In June-August 2022, we conducted 26 semistructured interviews with people in New York City who used unprescribed opioids. Interviews lasted 30-60 min and were conducted remotely using Zoom and later transcribed by a professional service. Data were then coded, using AtlasTi, into meaningful categories using a thematic approach based on the aims of the study and existing literature. RESULTS/UNASSIGNED:Most participants had heard of OnPoint and reported a willingness to use it. They described the ability of OnPoint staff to reverse an overdose quickly and the presence of naloxone, oxygen, and other supplies as the primary benefits. Yet, many also noted that OPCs provide PWUD with a place to escape from the weather and/or avoid law enforcement. Participants also reported concerns about how far PWUD would be willing to travel or wait to use an OPC and for the autonomy of PWUD in the context of formal, sanctioned OPCs. CONCLUSIONS/UNASSIGNED:Results suggest that many PWUD in NYC are well-informed about OnPoint and are willing to use OPCs. Yet, to fulfil their potential, OPCs must be located near to where PWUD live, and should be made as low-threshold as possible. However, since it is unlikely that OPCs will be expanded enough to meet the need and because some PWUD will never choose to use in sanctioned OPCs, expanding the reach of alternative strategies, such as Mobile Overdose Response Services, is recommended.

INTRODUCTION/UNASSIGNED:Methadone maintenance treatment (MMT) is among the best strategies for reducing harms associated with illegal opioid use, yet it is hindered by low rates of treatment initiation and retention that limit its impact. There has been a lack of studies that describe how people who use illegal opioids use methadone-both from opioid treatment programs, and bought illegally-over time, or what factors correlate with long-term participation in MMT. METHODS/UNASSIGNED: = 412 people who use illicit opioids in New York City from April 2019-2022. We used bivariate analyses to estimate the distribution of baseline sociodemographic and background characteristics. Multinomial logistic regression was then used to estimate the association between those characteristics and methadone use over time. RESULTS/UNASSIGNED:Findings show that people who are older, who used heroin for longer amounts of time, and who had multiple episodes of substance use disorder treatment other than medication for opioid use disorder are more likely to use MMT consistently over time. DISCUSSION/UNASSIGNED:Our findings may be related to the many barriers to long-term participation in MMT, such as travel distance, the need for regular attendance, and patients' dissatisfaction with opioid treatment programs. Consistent participation in MMT may become acceptable only when the difficulties and burdens of criminalized drug use begin to outweigh those of MMT participation, and after non-medication-using treatments have already been tried. Efforts to make MMT less burdensome could reduce the tendency to avoid MMT until later in life and improve people's consistency of participation over time.

BACKGROUND:Permanent supportive housing (PSH) is an evidence-based intervention for people experiencing homelessness which integrates permanent housing with voluntary support services. PSH tenants are at high risk for overdose death, yet little research to date has examined overdose in PSH. We sought to examine overdose risk and existing responses in PSH, which can shed light on opportunities for future overdose prevention efforts. METHODS:We conducted focus groups with PSH tenants, staff, and leaders in New York City and New York's Capital Region. Focus groups were recorded and professionally transcribed. Two investigators independently completed rapid turnaround qualitative analysis, completing templated summaries of each focus group and compiling key content in an analysis matrix, which a third investigator reviewed; discrepancies were resolved by consensus. RESULTS:From October to December 2022, we held 8 focus group sessions with PSH tenants (3 focus groups, n = 10 total participants), staff (3 focus groups, n = 13), and leaders (2 focus groups, n = 11) grouped by role and region. Participants were diverse in age (26-67 years), gender (18 women, 16 men), race (3 Asian, 12 Black, 11 White, 5 multiracial, 3 other), and ethnicity (5 Latinx, 29 not Latinx). Analysis revealed four main themes: (1) Overdose was a large concern in PSH and created significant trauma for tenants and staff; (2) Environmental factors in PSH contributed to overdose risk; (3) There was heterogeneity in PSH buildings' current overdose prevention efforts and adoption of harm reduction principles; and (4) Multifactorial barriers resulted in limited tenant use of opioid agonist treatment. CONCLUSIONS:Overdose is a major concern for PSH tenants, staff, and leaders. Our findings shed new light on overdose in PSH settings, providing insight into risk factors, existing responses, and barriers and facilitators to future overdose prevention efforts. These findings can inform future overdose prevention interventions within PSH. TRIAL REGISTRATION/BACKGROUND:ClinicalTrials.gov, NCT05786222, registered 27 March 2023.

BACKGROUND:Racial/ethnic and age-related disparities in HIV care continuum engagement are serious in the US. American/Black and Latine (AABL) young/emerging adults living with HIV have the lowest rates of engagement, but aspects of their experiences and some subpopulations are understudied. The present study is grounded in social action theory and uses a sequential explanatory mixed methods design to explore social interaction processes (e.g., social networks, trust), and their relationships to HIV management, in a diverse cohort including those with non-suppressed HIV viral load. METHODS: = 62) was purposively sampled for maximum variability for qualitative interviews. Quantitative data were analyzed with descriptive statistics and logistic regression. The primary outcomes were engagement in HIV care and viral suppression. Quantitative results were used to develop qualitative research questions, and qualitative data were analyzed with directed content analysis. Joint display methods were used to integrate results. RESULTS: = 0.045) increased the odds of viral suppression. In qualitative results we found social networks were vital to well-being, but, like participants, located in strained socioeconomic circumstances. In this context, we organized results into five themes: (1) social losses were disruptive to HIV management; (2) service settings and care providers were important network members; (3) family disapproval of sexual/gender minority status had negative effects; (4) immigrant participants were highly reliant on service settings; and (5) networks influenced participants’ drug use and their drug use also reduced the size and changed the composition of networks. CONCLUSIONS:The present study advances knowledge on social interaction processes among diverse AABL young/emerging adults living with HIV, and highlights points of intervention.

INTRODUCTION/BACKGROUND:The United States is facing an opioid use disorder (OUD) epidemic, marked by unprecedented overdose death rates. In New York State, synthetic opioids significantly contribute to the increasing overdose deaths, disproportionately impacting Black and Latinx communities. There is an urgent need to address issues related to equitable access to and the quality of care provided by substance use disorder (SUD) treatment programs. In light of this, the Quality Measurement and Management Research Center (QM2-RC) brought together an academic-government partnership to develop a person-centered quality measurement system and to assess its impact on a statewide treatment system that serves approximately 180,000 individuals per year. METHODS AND ANALYSIS/METHODS:The QM2-RC encompasses three interconnected projects (Project 1, 2, and 3) aimed at developing a quality management strategy and evaluating its impact on system performance across New York State. This report specifically focuses on Project 3, which involves a stepped-wedge trial with 35 clinics receiving a quality management intervention that includes performance coaching. This intervention will be compared to a treatment-as-usual (TAU) condition for clinics not participating in the trial. Administrative data will be utilized to monitor outcomes over four years. The coaching intervention, guided by the Integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) model, emphasizes interpreting quality measures and applying insights to enhance care. Coaches will provide support on data utilization, patient-centered care, harm reduction strategies, and the use of patient monitoring tools. The trial aims to evaluate clinic staff and leadership attitudes, experiences, and behaviors through surveys, semi-structured interviews, and external facilitator notes. Primary clinic outcomes will be assessed through adverse events, decreased clinic rates of substance use related emergency department visits and hospitalizations as well as mortality among patients within the first 12 months after admission to treatment after adjusting for individual and community level characteristics. This study is being developed over a multi-year period and will be informed by a mixed-methods approach incorporating multiple data sources, qualitative interviews, patient and clinic surveys. The study is being conducted in partnership with New York State Office of Addiction Services and Supports (OASAS) and will be informed by input from patient, providers, health insurers, family members and local governing units. DISCUSSION/CONCLUSIONS:Project 3 of the QM2 study specifically targets key barriers in measuring the quality of SUD treatment, including technological limitations, unvalidated measures, workforce data literacy, and concerns about fairness in assessing clinical complexity. Through the implementation of a stepped-wedge trial involving 35 clinics, the project aims to develop new quality measures, offer performance feedback, and engage clinic leadership and staff in efforts to improve practices. The ultimate goal of Project 3 is to overcome these barriers, promote person-centered care, and improve SUD treatment practices across New York State.
