238AbstractBackground: We explore injecting risk and HIV incidence among PWID in New York City (NYC), from 2012 to 2019, when incidence was extremely low, <0.1/100 person-years at risk, and during disruption of prevention services due to the COVID-19 pandemic. Methods: We developed an Agent-Based model (ABM) to simulate sharing injecting equipment and measure HIV incidence in NYC. The model was adapted from a previous ABM model developed to compare HIV transmission with “high” versus “low” dead space syringes. Data for applying the model to NYC during the period of very low HIV incidence was taken from the “Risk Factors” study, a long-running study of participants entering substance use treatment in NYC. Injecting risk behavior had not been eliminated in this population, with approximately 15 % reported recent syringe sharing. Data for possible transmission during COVID-19 disruption was taken from previous HIV outbreaks and early studies of the pandemic in NYC. Results: The modeled incidence rates fell within the 95 % confidence bounds of all of the empirically observed incidence rates, without any additional calibration of the model. Potential COVID-19 disruptions increased the probability of an outbreak from 0.03 to 0.25. Conclusions: The primary factors in the very low HIV incidence were the extremely small numbers of PWID likely to transmit HIV and that most sharing occurs within small, relatively stable, mostly seroconcordant groups. Containing an HIV outbreak among PWID during a continuing pandemic would be quite difficult. Pre-pandemic levels of HIV prevention services should be restored as quickly as feasible.Program Adaptations to Provide Harm Reduction Services During the COVID-19 Pandemic: A Qualitative Study of Syringe Services Programs in the U.S.

57-68AbstractSyringe services programs (SSPs) are essential to preventing injection drug use-related infections and overdose death among people who use drugs (PWUD). The novel coronavirus (COVID-19) pandemic initially impeded SSPs’ operations. To effectively support these programs, information is needed regarding SSPs’ experiences adapting their services and the challenges posed by COVID-19. We conducted qualitative interviews with leadership and staff from a sample of 31 U.S. SSPs. Respondents discussed urgent concerns including reduced reach of services, suspended HIV/hepatitis C testing, high COVID-19 risk among PWUD, and negative impacts of isolation on overdose and mental health. They also noted opportunities to improve future services for PWUD, including shifting to evidence-based distribution practices and maintaining regulatory changes that increased access to opioid use disorder medications post-pandemic. Findings can inform efforts to support SSPs in restoring and expanding services, and provide insight into SSPs’ role in engaging PWUD during the COVID-19 response and future emergencies.Recurrent Injecting Drug Use as a Mediator between Psychiatric Disorder and Non-Fatal Overdose

1248-1256AbstractBackground: Unintentional drug overdose has increased markedly in the United States. Studies document an association between psychiatric disorder and unintentional overdose; we extend this research through a preliminary test of a causal model of recurrent injection drug use mediating this relationship. Methods: In a cross-sectional study of 241 adults in New York City with a possible current substance use disorder, we conducted conventional and Imai’s mediation analyses to examine if psychiatric disorder is associated with increased prevalence of ever overdosing and if recurrent injection drug use mediates this association. Our cross-sectional data permit the first step of assessing causal models: testing if statistical associations are consistent with the model. Results: Fifty-eight percent of the sample endorsed previous psychiatric disorder diagnosis and 35.7% reported ever overdosing. Imai’s mediation analysis showed that, adjusting for covariates, the total association between psychiatric diagnosis and ever overdosing (adjusted prevalence difference [aPD] = 0.16, 95% CI 0.04–0.28) was composed of a direct effect (aPD = 0.09, 95% CI −0.03 − 0.21, p = 0.136) and an indirect effect (aPD = 0.07, 95% CI 0.02–0.13). Recurrent injecting drug use contributed to 42% (ratio of indirect effect to total effect; 95% CI 12 − 100%, p = 0.02) of the association between psychiatric diagnosis and ever overdosing. Conventional mediation analysis produced similar results. Conclusions: Our results provide a warrant for taking the necessary next step for assessing a causal model using longitudinal data, potentially providing a strong rationale for intervening on psychiatric disorders to stem overdose.Responding to a surge in overdose deaths: perspectives from US syringe services programs

1AbstractBackground: US overdose deaths have reached a record high. Syringe services programs (SSPs) play a critical role in addressing this crisis by providing multiple services to people who use drugs (PWUD) that help prevent overdose death. This study examined the perspectives of leadership and staff from a geographically diverse sample of US SSPs on factors contributing to the overdose surge, their organization’s response, and ongoing barriers to preventing overdose death. Methods: From 2/11/2021 to 4/23/2021, we conducted semi-structured interviews with leadership and staff from 27 SSPs sampled from the North American Syringe Exchange Network directory. Interviews were transcribed and qualitatively analyzed using a Rapid Assessment Process. Results: Respondents reported that increased intentional and unintentional fentanyl use (both alone and combined with other substances) was a major driver of the overdose surge. They also described how the COVID-19 pandemic increased solitary drug use and led to abrupt increases in use due to life disruptions and worsened mental health among PWUD. In response to this surge, SSPs have increased naloxone distribution, including providing more doses per person and expanding distribution to people using non-opioid drugs. They are also adapting overdose prevention education to increase awareness of fentanyl risks, including for people using non-opioid drugs. Some are distributing fentanyl test strips, though a few respondents expressed doubts about strips’ effectiveness in reducing overdose harms. Some SSPs are expanding education and naloxone training/distribution in the broader community, beyond PWUD and their friends/family. Respondents described several ongoing barriers to preventing overdose death, including not reaching certain groups at risk of overdose (PWUD who do not inject, PWUD experiencing homelessness, and PWUD of color), an inconsistent naloxone supply and lack of access to intranasal naloxone in particular, inadequate funding, underestimates of overdoses, legal/policy barriers, and community stigma. Conclusions: SSPs remain essential in preventing overdose deaths amid record numbers likely driven by increased fentanyl use and COVID-19-related impacts. These findings can inform efforts to support SSPs in this work. In the face of ongoing barriers, support for SSPs—including increased resources, political support, and community partnership—is urgently needed to address the worsening overdose crisis.Thick trust, thin trust, social capital, and health outcomes among trans women of color in New York City

214-231AbstractIntroduction: Many trans women of color communities experience high HIV seroprevalence, extreme poverty, high rates of victimization and substance use, and poor mental health. Greater knowledge of trans women of color social capital may contribute toward more effective services for this marginalized population. Methods: These data come from a mixed-methods study that examined trans/gender-variant people of color who attended transgender support groups at harm reduction programs in NYC. The study was conducted from 2011 to 12, total N = 34. The qualitative portion was derived from six focus group interviews. Results: Two support groups stood out as exhibiting very strong alternative kinship structures. One group was comprised of immigrant trans Latinas, and the other group were trans women of African descent living with HIV. Both groups demonstrated ample cultivation of “trust capital” in the form of “thick trust” (bonding capital) and “thin trust” (bridging/linking capital) both inside and outside/beyond the support groups. Thick trust included the cultivation of intimacy, support in primary romantic relationships, and community leadership. Thin trust included networking with a variety of organizations, increased educational opportunities, and cultural production. Discussion: Participants “opened up to social capital” through the process of trusting as a series of (1) risks; (2) vulnerabilities; and (3) reciprocities. A solid foundation of thick trust resulted in a social, psychological, and emotional “base.” Upon this foundation, thin trust was operationalized resulting in positive material, economic, and quality-of-life outcomes, leading to an expanded space of capabilities.“Maintaining HIV and HCV prevention and care for people who inject drugs despite COVID‐19 in Hai Phong, Vietnam”

110AbstractBackground: After the emergence of COVID-19, a one-month strict lockdown was imposed in April 2020 in Vietnam, followed by lighter social distancing restrictions over the year. We investigated whether those measures affected people who inject drugs (PWID) in terms of risk behaviors for HIV and HCV and access to prevention and care in the city of Haiphong, a historic hotspot for HIV and drug use. Methodology: We carried out a ‘before-after’ study from 2019 to 2020 using respondent-driven sampling method to enroll PWID. They were interviewed on their socioeconomic situation, drug use and sexual behaviors, relations to care services and tested for drugs and methadone in the urine, for HIV, HCV, and HIV plasma viral load when HIV-positive. Changes following the restrictions were assessed by comparing ‘before’ to ‘after’ data. Results: 780 PWID were enrolled. Mean age was 44 years; 94% were male. All were actively injecting heroin ‘before’, versus 56% ‘after’. Among those, frequency of consumption decreased from 24 to 17 days per month. No changes were observed in the frequency and practices of methamphetamine smoking. The proportion of PWID on MMT increased from 68.7% to 75.3%, and that of PWID engaging in risky behaviors related to drug injection decreased from 6.0% to 1.5%. No HIV seroconversions were observed; HCV incidence was 2.6/100 person-years (95% CI [0.7–6.7]). 9% of PWID reported a monthly income of less than 130USD ‘before’ versus 53% ‘after’. Conclusion: The case of Hai Phong shows that it is possible, during times of COVID-19 pandemic, to maintain access to harm reduction and care and to prevent HIV and HCV transmission among PWID in a resource-limited setting where severe social distancing restrictions are implemented. Further research is needed to assess the consequences of long-term economic difficulties and the impact of actual spread of SARS-Cov2 that has since emerged in Haiphong.A cohort study revealed high mortality among people who inject drugs in Hai Phong, Vietnam

38-48AbstractObjective: To estimate the residual mortality rate among people who inject drugs (PWID) in a Low-Middle Income Countries context where the HIV epidemic has been controlled and methadone coverage is high. Study design and setting: PWID from Haiphong, Vietnam, were recruited through three annual respondent-driven sampling surveys that fueled two cohorts of PWID with HIV (n = 761) and without HIV (n = 897), with bi-annual follow-up. Presumed causes of death were ascertained from medical records and/or interviews of participants family. Results: Among the 1658 participants with a median follow-up of 2 years, 67 and 36 died in the HIV-positive and HIV-negative cohort, respectively, yielding crude mortality rates of 4.3 (95% Confidence interval (CI): 3.3-5.4) per 100 person-years of follow-up (PYFU) and 1.9 (CI: 1.4-2.6) per 100 PYFU. In the HIV-positive cohort, in which 81% of participants had undetectable viral load, the two main causes of death were tuberculosis and HIV-related diseases. In the HIV-negative cohort, the two main causes of death were liver-related diseases and overdose. In a time-dependent multivariable model, “unsuppressed viral load” was associated with increased risk of mortality, whereas “being on methadone” or “being employed” was associated with a lower risk. Conclusion: Despite a very successful HIV and methadone program, the mortality remains high among PWID in Vietnam, largely due to curable infectious diseases such as tuberculosis and viral hepatitis.A Multistage Process Model of How a Person Who Currently Injects Drugs Comes to Assist Persons Who Do not Inject with Their First Injections

6AbstractInjecting drugs for the first time almost always requires assistance from an experienced person who injects drugs (PWID). While there has been moderate amount of research on PWID who assist with first injections, most of this research has focused on identifying characteristics of PWID who assist with first injections. We do not have a formal model that describes how the minority of PWID come to assist do so, while the majority never assist. Through comparison of persons who did or did not recently assist with first injections using data from PWID in Tallinn, Estonia (N = 286) and Staten Island, New York City (N = 101), we developed a formal multi-stage model of how PWID come to assist with first injections. The model had a primary pathway 1) of engaging in “injection promoting” behaviors, 2) being asked to assist, and 3) assisting. Statistical testing using odds ratios showed participation in each stage was strongly associated with participation in the next stage (all odds ratios >3.0) and the probabilities of assisting significantly increased with participation in the successive stages. We then used the model to compare engagement in the stages pre-vs. post participation in an intervention, and to compare persons who recently assisted to persons who had assisted in the past but had not recently assisted and to persons who had never assisted. Advantages of a formal model for how current PWID come to assist with first injections include: facilitating comparisons across different PWID populations and assessing strengths and limitations of interventions to reduce assisting with first injections.An application of agent-based modeling to explore the impact of decreasing incarceration rates and increasing drug treatment access on sero-discordant partnerships among people who inject drugs

94AbstractBackground: People who inject drugs (PWID) lag behind other key populations in HIV care continuum outcomes. The impacts of criminal justice reform and increasing drug treatment access on HIV have been underexplored. Methods: We developed agent-based models (ABM) of sexual partnerships among PWID and non-PWID, and injection equipment-sharing partnerships among PWID in five US cities (Baltimore, Boston, Miami, New York City, San Francisco) over 3 years. The first set of ABM projected changes in partnership discordance among PWID as a function of decreasing ZIP code-level incarceration rates. The second set projected discordance as a function of increasing ZIP code-level drug treatment access. ABM were parameterized and validated overall, and by city and PWID race/ethnicity (Black, Latino, White) using National HIV Behavioral Surveillance data, administrative ZIP code-level data, surveillance reports and prior literature. Informed by research on prisoner release and community-level HIV prevalence, reductions in incarceration rates were fixed at 5% and 30% and respectively projected to increase ZIP code-level HIV prevalence by 2% and 12%. Increases in drug treatment access were fixed at 30% and 58%. Results: In each city, a 30% reduction in ZIP code-level incarceration rates and 12% increase in ZIP code-level HIV prevalence significantly increased sero-discordance among at least one racial/ethnic group of PWID by 1–3 percentage points. A 5% reduction in incarceration rates, and 30% and 58% increases in drug treatment access, led to isolated significant changes in sero-discordance among Black and White PWID that were less than 1 percentage point. Conclusion: Reductions in incarceration rates may lead to short-term increases in sero-discordant partnerships among some PWID by increasing community-level HIV prevalence. Efforts to increase HIV testing, engagement in care and community reintegration post release, should be strengthened in the wake of incarceration reform. Additional research should confirm these findings and explore the lack of widespread impacts of drug treatment in this study.Behavioral correlates of COVID-19 worry: Stigma, knowledge, and news source

21AbstractNon-adherence to COVID-19 guidelines may be attributable to low levels of worry. This study assessed whether endorsing COVID-19-stigmatizing restrictions, COVID-19 knowledge, and preferred news source were associated with being ‘very worried’ versus ‘not at all’ or ‘somewhat’ worried about contracting COVID-19. Survey data were collected in July–August 2020 from N = 547 New York State (NYS) and N = 504 national Amazon MTurk workers. Respondents who endorsed COVID-19 stigmatizing restrictions (NYS OR 1.96; 95% CI 1.31, 2.92; national OR 1.80; 95% CI 1.06, 3.08) and consumed commercial news (NYS OR 1.89; 95% CI 1.21, 2.96; national OR 1.93; 95% CI 1.24, 3.00) were more likely to be very worried. National respondents who consumed The New York Times (OR 1.52; 95% CI 1.00, 2.29) were more likely to be very worried, while those with little knowledge (OR 0.24; 95% CI 0.13, 0.43) were less likely to be very worried. NYS (OR 2.66; 95% CI 1.77, 4.00) and national (OR 3.17; 95% CI 1.95, 5.16) respondents with probable depression were also more likely to be very worried. These characteristics can help identify those requiring intervention to maximize perceived threat to COVID-19 and encourage uptake of protective behaviors while protecting psychological wellbeing.Facilitating engagement of persons with opioid use disorder in treatment for hepatitis C virus infection via telemedicine: Stories of onsite case managers

127AbstractAlthough hepatitis C virus (HCV) infection has high prevalence and incidence in persons with opioid use disorder (PWOUD), their engagement in HCV care has been limited due to a variety of factors. In an ongoing multisite study at 12 opioid treatment programs (OTPs) throughout New York State (NYS), we have been evaluating telemedicine accompanied by onsite administration of direct acting antiviral (DAA) medications compared with usual care including offsite referral to a liver specialist for HCV management. Each site has a case manager (CM) who is responsible for all study-related activities including participant recruitment, facilitating telemedicine interactions, retention in care, and data collection. Our overall objective is to analyze CM experiences of clients' stories and events to understand how the telemedicine model facilitates HCV treatment. Hermeneutic phenomenology was used to interpret and to explicate common meanings and shared practices of the phenomena of case management, and a focus group with CMs was conducted to reinforce and expand on key themes identified from the CMs' stories. We identified three themes: (1) building trust, (2) identification of multiple competing priorities, and (3) development of personalized care approaches. Our results illustrate that trust is a fundamental pillar on which the telemedicine system can be based. Participants' experiences at the OTP can reinforce trust. Understanding the specific competing priorities and routinizing dedicated personalized approaches to overcome them are key to increasing participation in HCV care among PWOUD.Is the severity of the Great Recession's aftershocks correlated with changes in access to the combined prevention environment among people who inject drugs?

95AbstractBackground: The 2008 Recession was a global event that led to funding cuts for programs and services in the United States; though this recession officially ended in 2009, its aftershocks continued through 2012. We evaluated the relationship between the severity of the Great Recession's aftermath and spatial access to combined prevention services (i.e. HIV testing, syringe service programs, substance use disorder treatment program) for people who inject drugs (PWID) living in 19 metropolitan statistical areas (MSAs) in the United States. Methods: The unit of analysis was the ZIP code; we sampled ZIP codes in these 19 MSAs where ≥1 PWID lived in 2009 and 2012, according to the CDC's National HIV Behavioral Surveillance. We used administrative data to describe the combined prevention environment (i.e., spatial access to HIV testing) for each ZIP code, and measured the severity of the recession's aftermath in each ZIP code, and in the counties and MSAs where these ZIP codes were located. Multilevel modeling estimated associations between changes in the aftermath of the Great Recession and ZIP code-level changes in spatial access to combined prevention services from 2009 to 2012. Results: 675 ZIP codes located in 36 counties and 19 MSAs were included in this analysis. From 2009 to 2012, 21% of ZIP code areas lost access to combined prevention services and 14% gained access. ZIP codes with higher poverty rates relative to their respective MSAs were less likely to lose access (aOR: 0.91; 95% CI: 0.88, 0.95) and more likely to gain access (aOR: 1.05; 95% CI: 1.01, 1.09); there is some evidence to suggest the former association was attenuated for ZIP codes with higher percentages of non-Hispanic white residents. Conclusion: Combined prevention services for PWID living in these 675 ZIP codes demonstrated resilience in the aftermath of the Great Recession. Future research should explore whether community-based and federal HIV prevention initiatives contributed to this resilience, particularly in areas with higher concentrations of people of color.Is your syringe services program cost-saving to society?

1AbstractBackground: While there is a general acceptance among public health officials and policy-makers that syringe services programs can be effective in reducing HIV transmission among persons who inject drugs, local syringe services programs are often asked to provide economic justifications for their activities. A cost-effectiveness study, estimating the cost of preventing one HIV infection, would be the preferred methods for addressing this economic question, but few local syringe services programs have the needed data, staff and epidemiologic modeling resources needed for a cost–effectiveness study. We present a method for estimating a threshold value for the number of HIV infections prevented above which the program will be cost-saving to society. An intervention is considered “cost-saving” when it leads to a desirable health outcome a lower cost than the alternative. Methods: The research literature on the effectiveness of syringe services programs in controlling HIV transmission among persons who inject drugs and guidelines for syringe services program that are “functioning very well” were used to estimate the cost-saving threshold at which a syringe services program becomes cost-saving through preventing HIV infections versus lifetime treatment of HIV. Three steps are involved: (1) determining if HIV transmission in the local persons who inject drugs (PWID) population is being controlled, (2) determining if the local syringe services program is functioning very well, and then (3) dividing the annual budget of the syringe services program by the lifetime cost of treating a single HIV infection. Results: A syringe services program in an area with controlled HIV transmission (with HIV incidence of 1/100 person-years or less), functioning very well (with high syringe coverage, linkages to other services, and monitoring the local drug use situation), and an annual budget of $500,000 would need to prevent only 3 new HIV infections per year to be cost-saving. Conclusions: Given the high costs of treating HIV infections, syringe services programs that are operating according to very good practices (“functioning very well”) and in communities in which HIV transmission is being controlled among persons who inject drugs, will almost certainly be cost-saving to society.Mitochondrial genotoxicity of hepatitis c treatment among people who inject drugs

21AbstractAntiviral nucleoside analogues (ANA) are newly used therapeutics acting against the hepatitis C virus (HCV). This class of drug is well known to exhibit toxicity on mitochondrial DNA (mtDNA). People who inject drugs (PWID) are particularly affected by HCV infection and cumu-lated mitotoxic drug exposure from HIV treatments (antiretrovirals, ARV) and other illicit drugs. This study aims to explore the impact of direct-acting antiviral (DAA) treatments on mtDNA among PWID. A total of 470 actively injecting heroin users were included. We used quantitative PCR on whole blood to determine the mitochondrial copy number per cell (MCN) and the proportion of mitochondrial DNA deletion (MDD). These parameters were assessed before and after DAA treat-ment. MDD was significantly increased after HCV treatment, while MCN did not differ. MDD was even greater when subjects were cotreated with ARV. In multivariate analysis, we identified that poly-exposure to DAA and daily heroin injection or regular consumption of methamphetamines were positively associated with high MCN loss while DAA and ARV treatments or methadone use were identified as risk factors for having mtDNA deletion. These observations deserve attention since they were previously associated with premature cell ageing or cell transformation and there-fore call for a long-term follow-up.Place-Based Correlates of Exchange Sex Among People Who Inject Drugs in 19 U.S. Metropolitan Areas, 2012

2897-2909AbstractThis study examined overall and gender-specific associations between place-based characteristics and opposite-sex exchange sex among people who inject drugs (PWID) in the U.S. PWID were recruited from 19 metropolitan statistical areas (MSAs) for the Centers for Disease Control and Prevention’s 2012 National HIV Behavioral Surveillance. Administrative data were used to describe the economic, social, and political features of the ZIP codes, MSAs, counties, and states where PWID lived. Multilevel modeling estimated associations of place characteristics and exchange sex. We found that 52% of women and 23% of men reported past-year opposite-sex exchange sex (N = 7599). Female PWID living in states with stronger policies supporting working caregivers had lower odds of exchange sex (aOR = 0.80; 95% CI 0.69, 0.94). PWID living in ZIP codes with greater economic deprivation had higher odds of exchange sex (aOR = 1.10; 95% CI 1.03, 1.17). We found that a high percentage of male PWID exchanged sex with women; determinants and risks of this group merit exploration. If future research establishes that the relationships identified here are causal, interventions to reduce exchange sex among PWID should include policies supporting working caregivers and reducing poverty rates.Rapid point-of-care (POC) testing for Hepatitis C antibodies in a very high prevalence setting: persons injecting drugs in Tallinn, Estonia

1AbstractBackground: Between December 2018 and January of 2019, we evaluated the accuracy of the point-of-care Hepatitis C (HCV) antibody test (POC; OraQuick HCV) used at a community-based needle and syringe exchange program serving persons who inject drugs in Tallinn, Estonia. Methods: We compared the results of screening for HCV antibodies by OraQuick (oral swab) and enzyme immunoassay (EIA; blood draw) and assessed test results implications in a high prevalence setting. Findings Of the 100 participants, 88 (88%) had reactive POC test results, and 93 were HCV antibody positive on EIA testing. Sensitivity, specificity and negative predictive value (NPV) for the POC assay with EIA as the relevant reference test were as follows: 94.6% (95% CI 90.0–99.2%), 100% and 58.3% (95% CI 30.4–86.2%). Of the 12 testing, HCV-negative with the POC only 7 (58.3%) were true negatives. Conclusions: Oral swab rapid testing HCV screening in this nonclinical setting was sensitive and specific but had unacceptably low NPV. In high prevalence settings, POC tests with high sensitivity and that directly measure HCV RNA may be warranted.Sociodemographic and Behavioral Factors Associated With COVID-19 Stigmatizing Attitudes in the U.S.

371-379AbstractTo control the spread of coronavirus disease (COVID-19) and prevent further verbal and physical discrimination against individuals affected by, or perceived to be responsible for, COVID-19, proactive efforts must be made to ameliorate stigmatizing attitudes. This study seeks to examine whether key sociobehavioral factors including news consumption and contact with Chinese individuals are associated with COVID-19 stigma as a first step to informing stigma interventions. Surveys were administered to N = 498non-representative national respondents in August 2020 via Amazon’s Mechanical Turk and includedassessments of COVID-19 stigma, worry, knowledge, contact with COVID-19 and Chinese individuals, and preferred news source. Prevalence of stigmatizing beliefs was 65.46%. Odds of endorsing stigma were higher among males (OR = 1.77, 95% CI [1.07–2.93]) vs. females, Non-Hispanic Black (OR = 3.12, 95% CI [1.42–6.86]) and Hispanic (OR = 4.77, 95% CI [2.32–9.78]) vs. Non-Hispanic White individuals, and individuals with college degrees (OR = 3.41, 95% CI [1.94–5.99]) and more than college degrees (OR = 3.04, 95% CI [1.34–6.89]) vs. those with less than college degrees. Consumers (vs. non-consumers) of Fox News (OR = 4.43, 95% CI [2.52–7.80]) and social media (OR = 2.48, 95% CI [1.46–4.20]) had higher odds of endorsing stigma. Contact with Chinese individuals (OR = 0.50, 95% CI [0.25–1.00]) wasassociated with lower odds of endorsing stigma. These findings suggest that individuals of Non-HispanicBlack or Hispanic race/ethnic background, consumers of Fox News and social media, men, and individuals with college degrees or higher are groups that should be prioritized for anti-stigma intervention.Syringe Services Programs’ Role in Ending the HIV Epidemic in the U.S.: Why We Cannot Do It Without Them

S118-S129AbstractDiagnoses of HIV among people who inject drugs have increased in the U.S. during 2014–2018 for the first time in 2 decades, and multiple HIV outbreaks have been detected among people who inject drugs since 2015. These epidemiologic trends pose a significant concern for achieving goals of the federal initiative for Ending the HIV Epidemic in the U.S. Syringe services programs are cost effective, safe, and highly effective in reducing HIV transmission and are an essential component of a comprehensive, integrated approach to addressing these concerns. Yet, geographic coverage of these programs remains limited in the U.S., and many jurisdictions continue to have laws and policies that limit or disallow syringe services programs. An in-depth literature review was conducted on the role of syringe services programs in the Ending the HIV Epidemic initiative. Empirical and model-based evidence consistently shows that syringe services programs have the highest impact in HIV prevention when combined with access to medications for substance use disorder and antiretroviral therapy. Their effectiveness is further maximized when they provide services without restrictions and include proven and innovative strategies to expand access to harm-reduction and clinical services (e.g., peer outreach, telehealth). Increasing geographic and service coverage of syringe services programs requires strong and sustainable policy, funding, and community support and will need to address new challenges related to the COVID-19 pandemic. Syringe services programs have a key role in all 4 Ending the HIV Epidemic initiative strategies—Prevent, Diagnose, Treat, and Respond—and thus are instrumental to its success in preventing disease and saving lives.The methamphetamine epidemic among persons who inject heroin in Hai Phong, Vietnam

126AbstractAims: To describe the current methamphetamine (MA) use epidemic among persons who inject heroin (PWID) in Hai Phong, Vietnam, and consider possibilities for mitigating adverse effects of methamphetamine use. Methods: This study conducted surveys of PWID in 2016, 2017, and 2018 (N = 1383, 1451, and 1445, respectively). Trained interviewers administered structured interviews covering drug use histories, current drug use, and related risk behaviors. The study used urinalysis to confirm current drug use, and conducted HIV and HCV testing. Results: Participants were predominantly male (95%), mean age of 40, and all reported injecting heroin. Respondents' reports of initiating MA use were rare up through early 2000s but increased exponentially through the mid-2010s. MA use was predominantly “smoking,” heating the drug and inhaling the vapor using a pipe; injecting MA was rare. Current (past 30 day) MA use appears to have plateaued in 2016–2018 with 53–58% of participants reporting no use in the last 30 days, 37–41% reporting low to moderate use (1 to 19 days in last 30 days), and 5–7% reporting very frequent use (20 or more days in last 30 days). This plateau reflects a rough balance between new users and individuals ceasing use. Conclusions: MA use has become a substantial public health problem among PWID in Hai Phong. Initiation into MA use rose exponentially from 2005 to about 2015. Use of MA will likely continue for a substantial number of PWID. Currently, no medication is approved for treating MA disorders in Vietnam. Current psychosocial treatment requires highly trained counselors and months of treatment, so that psychosocial treatment for all PWID with MA disorders is likely beyond the resources available in a middle-income country such as Vietnam. Harm reduction programs implemented by community-based organization staff may provide a way to rapidly address aspects of the current MA epidemic. Such programs could emphasize social support for reducing use where possible and for avoiding escalation of use among persons continuing to use.Using large-scale respondent driven sampling to monitor the end of an HIV epidemic among persons who inject drugs in Hai Phong, Viet Nam

11AbstractAIMS: To describe the use of large-scale respondent driven sampling (RDS) surveys to demonstrate the "end of an HIV epidemic" (HIV incidence < 0.5/100 person-years) among persons who inject drugs (PWID) in a middle-income country. Large sample sizes are needed to convincingly demonstrate very low incidence rates.METHODS: 4 large surveys (Ns approximately 1500 each) were conducted among PWID in Hai Phong, Vietnam in 2016-2019. Respondent driven sampling (RDS) with a modification to add snowball sampling was used for recruiting participants. HIV incidence was measured through recency testing, repeat participants across multiple surveys and in a cohort study of PWID recruited from the surveys. RDS analytics (time to equilibria and homophilies for major variables) were used to assess similarities/differences in RDS only versus RDS plus snowball recruiting. Characteristics were compared among respondents recruited through standard RDS recruitment versus through snowball sampling. An overall assessment of the robustness of RDS to modification was made when adding a snowball sampling recruitment.RESULTS: RDS recruiting was very efficient in the first 5 weeks of each survey with approximately 180 respondents recruited per week. Recruiting then slowed considerably, and snowball sampling (permitting an individual respondent to recruit large numbers of new respondents) was added to the existing RDS recruiting. This led to recruiting within 13-14 weeks of 1383, 1451, 1444 and 1268 respondents, close to the target of 1500 respondents/survey. Comparisons of participants recruited through standard RDS method and respondents recruited through snowball methods showed very few significant differences. RDS analytics (quickly reaching equilibria, low homophilies) were favorable for both RDS recruited and total numbers of participants in each survey. DRug use and Infections in ViEtnam (DRIVE) methods have now been officially adopted in other provinces.CONCLUSIONS: RDS appears to be quite robust with respect to adding a modest number of participants recruited through snowball sampling. Large sample sizes can provide compelling evidence for "ending an HIV epidemic" to policy makers in a PWID population in a middle income country setting.A Delicate Balance

1875-1882AbstractObjective: We assessed the association between methamphetamine use and lack of viral suppression among a cohort of HIV-seropositive persons who inject drugs (PWID) in Hai Phong, Vietnam. Design: Cohort study with random effects logit modeling and mediation analysis for antiretroviral therapy (ART) adherence. Methods: PWID were recruited from October 2016 to October 2017; HIV-seropositive PWID were enrolled in a cohort to assess HIV viral loads, changes in drug use, risk behaviors, and ART adherence during 24-month follow-up. Methamphetamine use in last 30 days was divided into three categories: 0 days (no use), 1 – 19 days (intermediate), and 20 or more days (heavy). Bivariate and a multivariable random effects logit models were used to assess the relationship between methamphetamine use and not being virally suppressed. We also assessed self-reported ART adherence as a mediating factor. Results: A total of 645 HIV-seropositive PWID were included at baseline; 95% male, average age 40 (SD ¼ 6.4). At baseline, methamphetamine use in last 30 days was 64% no use, 32% intermediate use, 4% heavy use. Approximately 74% of PWID reported high/complete adherence; 76% were at viral suppression. In random effects analysis, recent methamphetamine use was associated with not being virally suppressed during follow-up (adjusted odds ratio: 1.84, 95% confidence interval: 1.06, 3.17); the effect was not explained by a mediating effect of self-reported adherence to ART. Conclusion: Recent methamphetamine use is associated with not being virally suppressed among PWID. The results of this study indicate the need for targeted interventions for methamphetamine use with special focus on those with HIV infection.Cost-effectiveness of direct antiviral agents for hepatitis c virus infection and a combined intervention of syringe access and medication-assisted therapy for opioid use disorders in an injection drug use population

2652-2662AbstractBackground: There are too many plausible permutations and scale-up scenarios of combination hepatitis C virus (HCV) interventions for exhaustive testing in experimental trials. Therefore, we used a computer simulation to project the health and economic impacts of alternative combination intervention scenarios for people who inject drugs (PWID), focusing on direct antiviral agents (DAA) and medication-assisted treatment combined with syringe access programs (MAT+). Methods. We performed an allocative efficiency study, using a mathematical model to simulate the progression of HCV in PWID and its related consequences. We combined 2 previously validated simulations to estimate the cost-effectiveness of intervention strategies that included a range of coverage levels. Analyses were performed from a health-sector and societal perspective, with a 15-year time horizon and a discount rate of 3%. Results. From a health-sector perspective (excluding criminal justice system-related costs), 4 potential strategies fell on the cost-efficiency frontier. At 20% coverage, DAAs had an incremental cost-effectiveness ratio (ICER) of $27 251/quality-adjusted life-year (QALY). Combinations of DAA at 20% with MAT+ at 20%, 40%, and 80% coverage had ICERs of $165 985/QALY, $325 860/ QALY, and $399 189/QALY, respectively. When analyzed from a societal perspective (including criminal justice system-related costs), DAA at 20% with MAT+ at 80% was the most effective intervention and was cost saving. While DAA at 20% with MAT+ at 80% was more expensive (eg, less cost saving) than MAT+ at 80% alone without DAA, it offered a favorable value compared to MAT+ at 80% alone ($23 932/QALY). Conclusions. When considering health-sector costs alone, DAA alone was the most cost-effective intervention. However, with criminal justice system-related costs, DAA and MAT+ implemented together became the most cost-effective intervention.Daily heroin injection and psychiatric disorders: A cross-sectional survey among People Who Inject Drugs (PWID) in Haiphong, Vietnam

216AbstractBackground: Psychiatric comorbidities are frequent among people who inject drugs, they are associated with a poorer prognosis and need to be addressed. Their interaction with daily heroin injection requires clarification. Methods: A cross-sectional survey was conducted among PWID recruited in the city of Haiphong, Vietnam, by respondent-driven sampling. The inclusion criteria were age 18 or older and current injection drug use, verified by skin marks and positive urine tests for heroin or methamphetamine. Data on socio-demographic characteristics, drug use, sexual behaviour and access to treatment were collected using face-to-face questionnaires by trained interviewers. PWID were screened by trained psychiatrists for depression, psychotic disorder and suicidality, using the MINI questionnaire. Results: 418 participants were included in the analyses. All were injected heroin users, 21 % were diagnosed with a current major depressive disorder, 15 % with a current psychotic disorder and 12 % presented a suicide risk. In the bivariate analyses, regular meth use, cannabis use and ketamine use were positively associated with presenting at least one psychiatric condition while daily heroin injection and being currently treated with methadone were negatively associated. In the multivariate model, poly-substance use was positively associated with depression (methamphetamine and drinking in addition to heroin) and psychotic disorder (methamphetamine and/or hazardous drinking in addition to heroin) while daily heroin injection and current methadone treatment were negatively and independently associated with depression and psychotic syndrome. Conclusions: Our survey confirms the burden of methamphetamine use and the protective effect of methadone but also a possible protective effect of daily heroin injection.DSM-5 substance use disorder symptom clusters and HIV antiretroviral therapy (ART) adherence

645-650AbstractThis study examines self-reported 30-day antiretroviral therapy (ART) adherence among 101 people living with HIV and substance use disorders (SUD) in New York City in terms of Diagnostic and Statistical Manual–5th Edition (DSM-5) SUD symptom clusters: impaired control, social impairment, risky use and pharmacological criteria. Overall, 60.4% met DSM-5 criteria for stimulant, 55.5% for alcohol, 34.7% for cannabis and 25.7% for opioid SUD. Of the 76 participants with a current ART prescription, 75.3% reported at least 90% 30-day adherence. Participants with vs. without alcohol SUD were significantly less likely to report ART adherence (64.3% vs. 88.2%, p =.017). Endorsement of social impairment significantly differed among adherent vs. non-adherent participants with alcohol SUDs (74.1% vs. 100%, p =.038) and with opioid SUDs (94.1% vs. 50.0%, p =.040). Understanding specific SUD symptom clusters may assist providers and patients in developing strategies to improve ART adherence.
