BackgroundPeople who use drugs (PWUD) experience elevated HIV risk and numerous barriers to facility-based HIV testing. HIV self-testing (HIVST) could circumvent many of those barriers and is acceptable among PWUD, yet HIVST implementation for PWUD is limited. Service providers' perspectives on specific HIVST delivery strategies could help increase availability for PWUD.MethodsFrom April-November 2021, we interviewed 16 health, harm reduction, and social service providers working with PWUD in San Diego, CA. Interviews and rapid thematic analysis explored perspectives on HIVST's utility and appropriateness, as well as the feasibility of and anticipated challenges with specific HIVST delivery strategies, including peer or secondary distribution.ResultsParticipants viewed HIV as a significant threat to PWUD health and confirmed the presence of numerous barriers to local facility-based HIV testing. Participants viewed HIVST as a promising and potentially empowering solution. Based on community familiarity with secondary distribution of harm reduction supplies (i.e., naloxone) and information, participants viewed secondary distribution of HIVST kits as an appropriate and feasible strategy for increasing the reach of HIVST, but also described potential barriers (e.g., engaging socially disconnected individuals, ensuring linkages to services following HIVST) and provided suggestions for alternative HIVST kit delivery models (e.g., harm reduction vending machines).ConclusionsService providers viewed secondary distribution of HIVST kits among PWUD as promising, appropriate, and feasible, yet specialized efforts may be needed to reach the most marginalized individuals and ensure consistent provision of educational information and referral supports that maximize the impact of this approach.

BackgroundHIV self-testing (HIVST) could increase HIV testing access among people who inject drugs (PWID), and secondary distribution (i.e., peer-delivery) of HIVST kits in PWID social networks could further expand coverage. We assessed willingness to use and distribute HIVST kits among PWID in the San Diego-Tijuana border region.MethodsFrom 2020 to 2021, HIV-negative PWID in San Diego, USA, and Tijuana, Mexico, completed surveys and provided data on individual (N = 539) and social network (N = 366) characteristics. We used modified Poisson regression to examine the effects of individual and social network characteristics on willingness to use and distribute HIVST kits.ResultsMost participants were willing to use (81%) and distribute (81%) HIVST kits. At the individual level, prior HIV testing was positively associated with willingness to use (adjusted prevalence ratio [aPR] = 1.24, 95% confidence interval [CI] 1.10-1.40) and distribute (aPR = 1.27, 95% CI 1.12-1.43) HIVST kits, while perceiving oneself to be at higher HIV risk than others was negatively associated with willingness to use HIVST kits (aPR = 0.83, 95% CI 0.74-0.93). At the network level, willingness to distribute HIVST kits was positively associated with network size (aPR = 1.04 per member, 95% CI 1.01-1.08) and greater proportions of one's network encouraging them to use drugs (aPR = 1.29, 95% CI 1.16-1.44) and having a history of homelessness (aPR = 1.51, 95% CI 1.31-1.74) or detention/arrest (aPR = 1.57, 95% CI 1.36-1.82), and negatively associated with a greater proportion of one's network including "very close" persons (aPR = 0.80, 95% CI 0.69-0.94).ConclusionsWe found high potential for HIVST kits and their secondary distribution to increase HIV testing among PWID who face the greatest barriers to facility-based testing.

BackgroundMeeting sex partners online is associated with increased risk of acquiring sexually transmitted infections. We examined whether different venues where men who have sex with men (MSM) meet sex partners was associated with prevalent Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection, and whether prevalence increased during (vs before) the COVID-19 pandemic.MethodsWe conducted a cross-sectional analysis of data from San Diego's 'Good To Go' sexual health clinic from two enrolment periods: (1) March-September 2019 (pre-COVID-19) and (2) March-September 2021 (during COVID-19). Participants completed self-administered intake assessments. This analysis included males aged ≥18 years self-reporting sex with males within 3 months before enrolment. Participants were categorised as (1) meeting new sex partners in-person only (eg, bars, clubs), (2) meeting new sex partners online (eg, applications, websites) or (3) having sex only with existing partners. We used multivariable logistic regression, adjusting for year, age, race, ethnicity, number of sex partners, pre-exposure prophylaxis use and drug use to examine whether venue or enrolment period were associated with CT/NG infection (either vs none).ResultsAmong 2546 participants, mean age was 35.5 (range: 18-79) years, 27.9% were non-white and 37.0% were Hispanic. Overall, CT/NG prevalence was 14.8% and was higher during COVID-19 vs pre-COVID-19 (17.0% vs 13.3%). Participants met sex partners online (56.9%), in-person (16.9%) or only had existing partners (26.2%) in the past 3 months. Compared with having only existing sex partners, meeting partners online was associated with higher CT/NG prevalence (adjusted OR (aOR) 2.32; 95% CI 1.51 to 3.65), while meeting partners in-person was not associated with CT/NG prevalence (aOR 1.59; 95% CI 0.87 to 2.89). Enrolment during COVID-19 was associated with higher CT/NG prevalence compared with pre-COVID-19 (aOR 1.42; 95% CI 1.13 to 1.79).ConclusionsCT/NG prevalence appeared to increase among MSM during COVID-19, and meeting sex partners online was associated with higher prevalence.

BackgroundWe evaluated the impact of a brief peer-led intervention on COVID-19 vaccination among people who inject drugs (PWID) presenting at syringe services program (SSP) locations in San Diego County, California.MethodsBetween March and July 2022, PWID aged ≥18 years without recent voluntary COVID-19 testing who were not up to date on COVID-19 vaccinations received a single-session motivational interviewing intervention (LinkUP) or an attention-matched didactic control condition from trained peer counselors at SSP sites randomized by week. Following either 30-minute session, counselors offered referrals to local vaccination services. Multivariable log binomial regression via generalized estimating equations assessed LinkUP effects on (1) acceptance of COVID-19 vaccination referrals immediately postintervention and (2) COVID-19 vaccine uptake at 6-month follow-up.ResultsCOVID-19 vaccination outcomes were obtained on 135 (90.6%) of 149 participants. In multivariable analysis, participants receiving LinkUP had greater acceptance of COVID-19 vaccination referrals than controls (adjusted relative risk, 3.50; 95% CI, 1.01-12.2) and were marginally more likely to report receiving a new COVID-19 vaccine dose (adjusted relative risk, 1.57; 95% CI, .99-2.48). After 6 months, 20% reported receiving a new vaccine dose; however, if COVID-19 vaccine had been available at SSPs, this proportion could have been as high as 34.3% (45.3% LinkUP vs 24.3% control; P = .01).ConclusionsA brief peer-led SSP-based intervention significantly improved COVID-19 vaccination among PWID. Further improvements could likely be obtained by supporting SSPs to offer COVID-19 vaccination on-site instead of relying on referrals.Clinical trials registrationClinicalTrials.gov NCT05181657.

BackgroundPeople who use drugs (PWUD) in the San Diego, USA and Tijuana, Mexico metroplex face high overdose risk related to historic methamphetamine use and relatively recent fentanyl introduction into local drug supplies. The personal overdose experiences of PWUD in this region are understudied, however, and may have been influenced by the COVID pandemic.MethodsFrom September-November 2021, we conducted 28 qualitative interviews among PWUD ≥18 years old sampled from an ongoing cohort study in the San Diego-Tijuana metroplex. Interviews explored overdose experiences and changes in the drug supply. Thematic analysis of coded interview transcripts explored overdose experiences, perspectives on drug supply changes, interactions with harm reduction services, and naloxone access.ResultsAmong 28 participants, 13 had experienced an overdose. Participants discussed rising levels of fentanyl in local drug supplies and increasing overdose incidents in their social networks. Participants discussed a general shift from injecting heroin to smoking fentanyl in their networks. Participants' most common concerns included having consistent access to a safe and potent drug supply and naloxone.ConclusionParticipants prioritized adapting to drug supply changes and preventing overdose compared to other health concerns, such as HIV and COVID-19. Efforts to address overdose in this region could benefit from drug checking services and expanded, equitable delivery of naloxone.

BackgroundPeople who inject drugs (PWID) have low rates of COVID-19 testing yet are vulnerable to severe disease. In partnership with a mobile syringe service program (SSP) in San Diego County, CA, we developed the evidence-, community-, and Social Cognitive Theory-informed "LinkUP" intervention (tailored education, motivational interviewing, problem-solving, and planning) to increase COVID-19 testing uptake among PWID.PurposeTo assess preliminary efficacy of LinkUP in increasing PWID COVID-19 testing in a pilot randomized controlled trial (RCT).MethodsWe referred participants (PWID, ≥18 years old, San Diego County residents who had not recently undergone voluntary COVID-19 testing) to mobile SSP sites that had been randomized (by week) to offer the active LinkUP intervention or didactic attention-control conditions delivered by trained peer counselors. Following either condition, counselors offered on-site rapid COVID-19 antigen testing. Analyses estimated preliminary intervention efficacy and explored potential moderation.ResultsAmong 150 participants, median age was 40.5 years, 33.3% identified as Hispanic/Latinx, 64.7% were male, 73.3% were experiencing homelessness, and 44.7% had prior mandatory COVID-19 testing.

IntroductionWe studied characteristics of COVID-19 vaccination uptake among people who inject drugs (PWID).MethodsParticipants aged ≥18 years who injected drugs ≤1 month ago were recruited into a community-based cohort from October 2020 to September 2021 in San Diego, California Poisson regression identified correlates of having had ≥1 COVID-19 vaccine dose based on semi-annual follow-up interviews through March 15, 2022.ResultsOf 360 participants, 74.7% were male, mean age was 42 years; 63.1% were Hispanic/Mexican/Latinx. More than one-third had ≥1 co-morbidity. HIV and HCV seroprevalence were 4.2% and 50.6% respectively; 41.1% lacked health insurance. Only 37.8% reported having ≥1 COVID-19 vaccine dose. None received ≥3 doses. However, of those vaccinated, 37.5% were previously unwilling/unsure about COVID-19 vaccines. Believing COVID-19 vaccines include tracking devices (adjusted incidence rate ratio [aIRR]: 0.62; 95% CI: 0.42,0.92) and lacking health insurance (aIRR: 0.60; 95% CI: 0.40,0.91) were associated with approximately 40% lower COVID-19 vaccination rates). Ever receiving influenza vaccines (aIRR: 2.16; 95%CI: 1.46, 3.20) and testing HIV-seropositive (aIRR: 2.51; 95% CI: 1.03, 6.10) or SARS-CoV-2 RNA-positive (aIRR: 1.82; 95% CI: 1.05, 3.16) independently predicted higher COVID-19 vaccination rates. Older age, knowing more vaccinated people, and recent incarceration were also independently associated with higher COVID-19 vaccination rates.ConclusionsOne year after COVID-19 vaccines became available to U.S. adults, only one third of PWID had received ≥1 COVID-19 vaccine dose. Multi-faceted approaches that dispel disinformation, integrate public health and social services and increase access to free, community-based COVID-19 vaccines are urgently needed.

BackgroundHIV outbreaks among people who inject drugs (PWID) and experience homelessness are increasing across the USA. Despite high levels of need, multilevel barriers to accessing antiretroviral pre-exposure prophylaxis (PrEP) for HIV prevention persist for this population. The Boston Health Care for the Homeless Program (BHCHP) initiated a low-threshold, outreach-based program to support engagement in PrEP services among PWID experiencing homelessness.MethodsTo inform dissemination efforts, we explored patient and provider perspectives on key program components. From March to December 2020, we conducted semi-structured qualitative interviews with current and former BHCHP PrEP program participants and prescribers, patient navigators, and outreach workers (i.e., providers). Thematic analysis explored perspectives on key program components.ResultsParticipants (n = 21) and providers (n = 11) identified the following five key components of BHCHP's PrEP program that they perceived to be particularly helpful for supporting patient engagement in PrEP services: (1) community-driven PrEP education; (2) low-threshold, accessible programming including same-day PrEP prescribing; (3) tailored prescribing supports (e.g., on-site pharmacy, short-term prescriptions, medication storage); (4) intensive outreach and navigation; and (5) trusting, respectful patient-provider relationships.DiscussionFindings suggest that more patient-centered services formed the basis of BHCHP's innovative, successful PrEP program. While contextual challenges including competing public health emergencies and homeless encampment "sweeps" necessitate ongoing programmatic adaptations, lessons from BHCHP's PrEP program can inform PrEP delivery in a range of community-based settings serving this population, including syringe service programs and shelters.

BackgroundHIV incidence has recently increased among people who inject drugs (PWID) across the United States, with outbreaks occurring in states with long-standing syringe service programs (SSPs) including Massachusetts (MA). Antiretroviral pre-exposure prophylaxis (PrEP) is an evidence-based HIV prevention strategy recommended for PWID, but uptake in this marginalized population is extraordinarily low.MethodsWe describe the design and procedures for a National Institute on Drug Abuse (NIDA)-funded (R01) randomized controlled trial (RCT) testing the efficacy of "PrEP for Health," a multicomponent behavioral intervention to increase PrEP uptake, adherence, and persistence among HIV-negative PWID attending SSPs in two areas of the U.S. Northeast that are heavily affected by injection-related HIV transmission. Participants are equally randomized to receive the "PrEP for Health" intervention (involving individually tailored HIV and PrEP education, motivational interviewing, problem-solving skills and planning, and ongoing navigation support) or an enhanced standard of care (eSOC) control condition involving a brief educational video on the utility of PrEP for HIV prevention. Co-primary outcomes are PrEP uptake (using medical/pharmacy records) and adherence (using tenofovir quantification in hair samples); a secondary outcome is PrEP persistence (using medical/pharmacy records) over 12 months. Major assessments occur at baseline, 1-, 3-, 6-, and 12-month follow-up visits. Planned analyses will examine intervention efficacy, specific hypothesized conceptual mediators of the intervention effect (e.g., self-perceived HIV risk; PrEP knowledge, interest in use, motivation, and behavioral skills) and epidemiologically linked moderators (e.g., age; gender; condomless vaginal or anal sex).DiscussionFindings from our extensive preliminary research with the study population revealed that a multicomponent, theory-based intervention targeting PrEP knowledge, motivation, self-efficacy, behavioral skills, and structural barriers to PrEP access is urgently needed for PWID who are at risk of HIV acquisition. We also learned that SSPs represent a highly acceptable service setting for delivering such interventions. In this study, we are evaluating the efficacy of the "PrEP for Health" intervention. If efficacious, findings from our implementation evaluation could help guide its dissemination to diverse SSPs and possibly other community-based settings accessed by this population.Trial registrationClinicalTrials.gov number NCT04430257, registered June 12, 2020.

BackgroundIn the context of increasing injection-related HIV outbreaks across the United States, particularly among people who inject drugs (PWID) experiencing homelessness, there is an urgent need to expand access to pre-exposure prophylaxis (PrEP) for HIV prevention. Peer-based interventions for PrEP could be helpful for promoting PrEP uptake, yet the social experiences of using PrEP among PWID experiencing homelessness have not been thoroughly explored.MethodsTo better understand social experiences surrounding PrEP use among PWID experiencing homelessness, we conducted qualitative interviews from March-December 2020 with current and former PrEP patients of an innovative, low-threshold program implemented by Boston Health Care for the Homeless Program (BHCHP) in Boston, MA. Thematic analysis of coded interview data explored participants' perspectives and experiences with PrEP disclosure and discussions within their social networks.ResultsAmong interviews with 21 participants, we identified the following four interrelated aspects of their social experiences using PrEP: (1) participants' were aware of increasing HIV transmission within their social networks, which motivated their PrEP use and disclosure; (2) participants generally avoided disclosing their PrEP use within public spaces or casual conversations; (3) participants expressed greater willingness to discuss PrEP with their close social contacts; and (4) some participants self-identified as leaders or expressed interest in leading the dissemination of PrEP information within their social networks.ConclusionsFindings highlight the significance of PrEP disclosure and discussions within the social networks of PWID experiencing homelessness, suggesting a need for continued social network and intervention research-particularly to establish the feasibility and acceptability of peer-based interventions for promoting PrEP-with this marginalized population.

BackgroundSyringe service programs (SSPs) provide essential harm reduction and prevention services for people who inject drugs in the USA, where SSP coverage is expanding. During the COVID-19 pandemic, US SSPs underwent unprecedented shifts in operational procedures (e.g., closures of physical sites, staff redeployment into pandemic response efforts). Given the critical role of US SSP workers in the pandemic, we sought to explore the occupational experiences and well-being of SSP staff to inform future emergency response efforts.MethodsFrom July-October 2020, we conducted semi-structured interviews with staff members of four SSPs in diverse regions of Massachusetts. Trained interviewers administered qualitative interviews virtually. Interviews were coded in NVivo v12 and thematic analysis identified common occupational experiences and related impacts on staff well-being in the context of the COVID-19 pandemic.ResultsAmong 18 participants, 12 (67%) had client-facing roles such as harm reduction specialists and six (33%) worked in program management or leadership. We found that staff were frequently anxious about SARS-CoV-2 transmission, which contributed to staff turnover. SSPs rapidly adapted and expanded their services to meet increasing client needs during the pandemic (e.g., food distribution, COVID-19 testing), leading to staff overexertion. Simultaneously, public health measures such as physical distancing led to staff concerns about reduced social connections with clients and coworkers. Through these challenges, SSPs worked to protect staff well-being by implementing flexible and tangible COVID-19-related policies (e.g., paid sick leave), mental health resources, and frequent communication regarding pandemic-related operational changes.ConclusionSSPs in the USA adapted to the COVID-19 pandemic out of necessity, resulting in operational changes that threatened staff well-being. Despite the protective factors revealed in some narratives, our findings suggest that during prolonged, complex public health emergencies, SSPs may benefit from enhanced occupational supports to prevent burnout and promote wellness for this essential public health workforce.

BackgroundSafe consumption sites (SCSs) serve diverse populations of people who use drugs (PWUD) and public health objectives. SCS implementation began in the 1980s, and today, there are at least 200 known SCSs operating in over twelve countries. While a growing literature supports their effectiveness as a harm reduction strategy, there is limited information on contextual factors that may support or hinder SCS implementation and sustainability. We aimed to fill this gap in knowledge by reviewing existing qualitative studies on SCSs.MethodsWe conducted a systematic review and thematic synthesis of qualitative studies. We identified all peer-reviewed, English-language qualitative studies on SCSs containing original data in PubMed, Web of Science, Google Scholar, and Science Direct as of September 23, 2019. Two authors independently screened, abstracted, and coded content relating to SCS implementation and sustainment aligned with the Exploration, Preparation, Implementation, Sustainment (EPIS) implementation science framework.ResultsAfter removing duplicates, we identified 765 unique records, of which ten qualitative studies met inclusion criteria for our synthesis. Across these ten studies, 236 total interviews were conducted. Overall, studies described how SCSs can (1) keep drug use out of public view while fostering a sense of inclusion for participants, (2) support sustainment by enhancing external communities' acceptability of SCSs, and (3) encourage PWUD utilization. Most studies also described how involving PWUD and peer workers (i.e., those with lived experience) in SCS operation supported implementation and sustainability.DiscussionOur thematic synthesis of qualitative literature identified engagement of PWUD and additional factors that appear to support SCS planning and operations and are critical to implementation success. However, the existing qualitative literature largely lacked perspectives of SCS staff and other community members who might be able to provide additional insight into factors influencing the implementation and sustainability of this promising public health intervention.

BackgroundPeople who inject drugs (PWID) face increased risk of SARS-CoV-2 acquisition and severe disease, yet COVID-19 vaccine uptake has been suboptimal. To inform vaccination interventions tailored for the needs of this population, we explored COVID-19 vaccination acceptability and experiences among PWID in San Diego County, USA.MethodsFrom September-November 2021, we conducted qualitative interviews with PWID aged ≥18 years who were participating in a prospective study of infectious disease risks in San Diego. Thematic analysis of coded interview transcripts focused on identifying barriers and facilitators to COVID-19 vaccination.ResultsOf 28 participants, 15 reported having had ≥1 dose of COVID-19 vaccine, primarily received through community health centers, pharmacies, jails, and homeless shelters. We identified three key barriers to COVID-19 vaccination: (1) low perceived risk of COVID-19 (or belief in natural immunity), (2) institutional distrust (e.g., of pharmaceutical companies and government agencies that "rushed" vaccine development, approval, and distribution), and (3) conflicting information from news, social media, and peers. We also identified three key facilitators of vaccination, including (1) heightened personal and interpersonal safety concerns, (2) health service outreach efforts to make vaccines more accessible, and (3) tailored information delivered by trusted sources (e.g., outreach or community health workers).ConclusionsTailored intervention strategies to increase acceptability and uptake of COVID-19 vaccination among PWID should involve efforts to increase vaccine literacy and motivation while decreasing institutional distrust and structural barriers to access.

BackgroundPeople who inject drugs (PWID) are vulnerable to acquiring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We examined correlates of coronavirus disease 2019 (COVID-19) vaccine hesitancy among PWID in the US-Mexico border region, of whom only 7.6% had received ≥ 1 COVID-19 vaccine dose by September 2021.MethodsBetween October 2020 and September 2021, participants aged ≥ 18 years from San Diego, California, USA, and Tijuana, Baja California, Mexico, who injected drugs within the last month completed surveys and SARS-CoV-2, human immunodeficiency virus (HIV), and hepatitis C virus (HCV) serologic testing. Logistic regressions with robust standard error estimation via generalized estimating equations identified factors associated with being unsure or unwilling to receive COVID-19 vaccines.ResultsOf 393 participants, 266 (67.7%) were willing to receive COVID-19 vaccines and 127 (32.3%) were hesitant (23.4% unwilling and 8.9% unsure). Older participants, those with greater food insecurity, and those with greater concern about acquiring SARS-CoV-2 were more willing to be vaccinated. Higher numbers of chronic health conditions, having access to a smart phone or computer, and citing social media as one's most important source of COVID-19 information were independently associated with vaccine hesitancy. COVID-19-related disinformation was independently associated with vaccine hesitancy (adjusted odds ratio: 1.51 per additional conspiracy theory endorsed; 95% confidence interval: 1.31-1.74).ConclusionsNearly one third of people injecting drugs in the US-Mexico border region were COVID-19 vaccine hesitant, which was significantly associated with exposure to social media, disinformation and co-morbidities and inversely associated with food security and high perceived threat of COVID-19. Interventions that improve accurate knowledge of and trust in COVID-19 vaccines are needed in this vulnerable population.

People who inject drugs (PWID) have extraordinarily low uptake of human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) despite high levels of need. Long-acting PrEP modalities hold promise for HIV prevention among PWID, but product preferences remain poorly understood. From September to November 2021, we conducted qualitative interviews with 28 HIV-negative, adult (≥18 years) PWID in San Diego County, CA, to explore their perspectives on daily oral PrEP pills and long-acting PrEP modalities (i.e., injections, implants, intravaginal rings, and broadly neutralizing antibodies), which we explained using standard scripts. Thematic analysis identified variations in PrEP modality interest and acceptability. We identified three key factors across the 28 interviews that appeared to influence PrEP modality preferences: perceived convenience of use, invasiveness, and familiarity (based on past experience). Overall, most participants preferred injectable PrEP over other modalities because they viewed injectable medications as convenient, noninvasive, and familiar. While injectable PrEP was recently approved for use in the United States and was most the acceptable PrEP modality in this sample, our findings suggest that intervention and implementation research is urgently needed to improve our understanding of strategies that could support access, uptake, and sustained adherence to longer-acting PrEP for PWID.

AbstractThe impact of preexposure prophylaxis uptake on sexual and injection-related behaviors among women who inject drugs is poorly understood. Over 24 weeks, preexposure prophylaxis uptake among women who inject drugs was associated with increased sharing of injection equipment but not syringes and no changes in condomless sex, providing limited evidence of risk compensation in this vulnerable population.

BackgroundEfforts to reduce opioid overdose fatalities have resulted in tapering (i.e., reducing or discontinuing) opioid prescriptions despite a limited understanding of patients' experiences.ObjectiveTo explore patients' perspectives on opioid taper experiences to ultimately improve taper processes and outcomes.DesignQualitative study.ParticipantsPatients on long-term opioid therapy for chronic pain who had undergone a reduction of opioid daily prescribed dosage of ≥50% in the past 2 years in two distinct medical systems and regions.ApproachFrom 2019 to 2020, we conducted semi-structured interviews that were audio-recorded, transcribed, systematically coded, and analyzed to summarize the content and identify key themes regarding taper experiences overall and with particular attention to patient-provider relationships and provider communication during tapers.Key resultsParticipants (n=41) had lived with chronic pain for an average of 17.4 years (range, 3-36 years) and described generally adverse experiences with opioid tapers, the initiation of which was not always adequately justified or explained to them. Consequences of tapers ranged from minor to substantial and included withdrawal, mobility issues, emotional distress, exacerbated mental health symptoms, and feelings of social stigmatization for which adequate supports were typically unavailable. Narratives highlighted the consequential role of patient-provider relationships throughout taper experiences, with most participants describing significant interpersonal challenges including poor provider communication and limited patient engagement in decision making. A few participants identified qualities of providers, relationships, and communication that fostered more positive taper experiences and outcomes.ConclusionsFrom patients' perspectives, opioid tapers can produce significant physical, emotional, and social consequences, sometimes reducing trust and engagement in healthcare. Patient-provider relationships and communication influence patients' perceptions of the quality and outcomes of opioid tapers. To improve patients' experiences of opioid tapers, tapering plans should be based on individualized risk-benefit assessments and involve patient-centered approaches and improved provider communication.

Although the correlation between experience of intimate partner violence (IPV) and substance use among women has been well-established, there is no consensus on whether or how IPV impacts subsequent substance use behaviors or treatment success. To identify research gaps and implications for substance use treatment, we conducted a systematic review to identify and examine evidence on IPV as a predictor of subsequent substance use behaviors, substance use disorders (SUD), and treatment outcomes among women. We included studies published between 2010 and 2020 that assessed IPV experiences as a predictor of subsequent substance use behaviors (i.e., use initiation, increased use), SUD diagnosis, or treatment outcomes (i.e., incomplete treatment, relapse) among women. From 576 unique records, we included 10 studies (4 longitudinal, 4 cross-sectional, 2 qualitative). Alcohol use and alcohol use disorder were the most commonly studied outcomes (n = 6); findings were mixed regarding the significance of IPV being associated with subsequent alcohol outcomes. Three studies examined illicit drug use, finding that physical and sexual IPV predicted crack/cocaine use and were associated with SUD diagnoses. Four studies examining SUD treatment outcomes found IPV to impede treatment engagement and completion, increasing the likelihood of relapse. To our knowledge, this is the first systematic review of the literature on IPV as a predictor of substance use behaviors and treatment outcomes among women. Findings highlight the need for diverse SUD treatment modalities to incorporate IPV screening and referral to appropriate services into their programming to improve SUD management and the overall health and wellbeing of women.

BackgroundPeople who inject drugs (PWID) have low rates of COVID-19 testing and vaccination and are vulnerable to severe disease. We partnered with a local, community-based syringe service program (SSP) in San Diego County, CA, to develop the single-session theory- and evidence-informed "LinkUP" intervention to increase COVID-19 testing and vaccination. This paper details the protocol for a pilot randomized controlled trial (RCT) of the LinkUP intervention.MethodsWith significant community input into study design considerations, including through our Community and Scientific Advisory Board, the LinkUP pilot RCT leverages an ongoing cohort study with adult (≥ 18 years) PWID in San Diego County to recruit participants who have not recently undergone voluntary COVID-19 testing and are unvaccinated. Eligible participants are referred to SSP locations randomized to offer the active intervention (involving tailored education, motivational interviewing, and problem-solving strategies) or a didactic attention-control condition (information sharing only). Both conditions are delivered by trained peer counselors hired by the SSP and were designed to be delivered at mobile (outdoor) SSP sites in ~ 30 min. Intake data assesses COVID-19 testing and vaccination history, health status, and harm reduction needs (to facilitate SSP referrals). At the end of either intervention condition, peer counselors offer onsite rapid COVID-19 antigen testing and COVID-19 vaccination referrals. Out-take and follow-up data (via SSP and state health department record linkages) confirms whether participants received the intervention, COVID-19 testing (and results) onsite or within six months, and vaccination referrals (and uptake) within six months. Planned analyses, which are not powered to assess efficacy, will provide adequate precision for effect size estimates for primary (COVID-19 testing) and secondary (vaccination) intervention outcomes. Findings will be disseminated widely including to local health authorities, collaborating agencies, and community members.DiscussionLessons from this community-based pilot study include the importance of gathering community input into study design, cultivating research-community partnerships based on mutual respect and trust, and maintaining frequent communication regarding unexpected events (e.g., police sweeps, neighborhood opposition). Findings may support the adoption of COVID-19 testing and vaccination initiatives implemented through SSPs and other community-based organizations serving vulnerable populations of people impacted by substance use and addiction. Trial registration This trial was registered prospectively at ClinicalTrials.gov (identifier NCT05181657).

BackgroundDrug use is a growing concern in Ghana. People who inject drugs (PWID) are highly vulnerable to HIV and other infectious diseases. Ghana's National Strategic Plan for HIV/AIDS 2016-2020 identifies PWID as a key population, but efforts to address the needs of PWID have lagged behind those targeting sex workers and men who have sex with men. Lack of information about PWID is a critical barrier to implementing effective HIV prevention and treatment. We aimed to learn more about the vulnerability of the PWID population in order to inform much-needed harm reduction interventions.MethodsFrom April to July 2018, we conducted a mixed methods study in Kumasi, Ghana, to identify all major drug using locations, count the numbers of PWID to obtain rough population size estimations, and administer anonymous surveys to 221 PWID regarding drug use and sexual behavior. We also tested for HIV, HCV, and HBV from syringes used by survey participants.ResultsKey informants identified five major drug using locations and estimated the total PWID population size to be between 600 and 2000. Enumerators counted between 35 and 61 individuals present at each of the five bases. Sharing syringes and reusing discarded syringes are common practices. Over half of survey participants (59%) reported past-month syringe sharing (34% used a used syringe and 52% gave away a used syringe). Individuals with higher injection frequency (≥ 21 times weekly) and who injected with four or more people had higher odds of syringe sharing. Of the survey participants reporting sex in the last month (23%), most reported having one partner, but only 12% used condoms. Nearly all women (11/13) reported exchanging sex for drugs and 6/13 reported exchanging sex for money in the last six months. Fifteen percent of participants (all men) reported paying for sex using drugs or money. Of the used syringes, prevalence estimates were 3% (HIV), 2% (HCV), and 9% (HBV).ConclusionsOur findings confirm the urgent need to implement harm reduction interventions targeting PWID and to build a strong and enabling legal and policy environment in Ghana to support these efforts.

ContextSupervised injection facilities are harm reduction interventions that allow people who inject drugs to use previously obtained substances under the supervision of health professionals. Although currently considered illegal under U.S. federal law, several U.S. cities are considering implementing supervised injection facilities anyway as a response to the escalating overdose crisis. The objective of this review is to determine the effectiveness of supervised injection facilities, compared with that of control conditions, for harm reduction and community outcomes.Evidence acquisitionStudies were identified from 2 sources: a high-quality, broader review examining supervised injection facility-induced benefits and harms (from database inception to January 2014) and an updated search using the same search strategy (January 2014‒September 2019). Systematic review methods developed by the Guide to Community Preventive Services were used (screening and analysis, September 2019‒December 2020).Evidence synthesisA total of 22 studies were included in this review: 16 focused on 1 supervised injection facility in Vancouver, Canada. Quantitative synthesis was not conducted given inconsistent outcome measurement across the studies. Supervised injection facilities in the included studies (n=number of studies per outcome category) were mostly associated with significant reductions in opioid overdose morbidity and mortality (n=5), significant improvements in injection behaviors and harm reduction (n=7), significant improvements in access to addiction treatment programs (n=7), and no increase or reductions in crime and public nuisance (n=7).ConclusionsFor people who inject drugs, supervised injection facilities may reduce the risk of overdose morbidity and mortality and improve access to care while not increasing crime or public nuisance to the surrounding community.

ObjectivesElective surgical patients with unhealthy alcohol use have unique pain management needs and addiction risk factors that are relevant to surgical preparation and recovery. This descriptive qualitative study sought to better understand patients' beliefs and behaviors related to opioid use, alcohol use, and pain management in the perioperative context.DesignWe conducted individual semi-structured interviews between July 2017 and March 2018.SettingA large Midwestern academic health system.SubjectsParticipants were elective surgical patients meeting unhealthy alcohol use criteria, recruited from the health system's preoperative anesthesia clinic.MethodSemistructured interview guides explored beliefs and behaviors relating to alcohol and opioid use, health status, and surgical care. Interview recordings were transcribed and coded for thematic analysis.ResultsAmong 20 elective surgical patients (25% female), we identified three key themes regarding alcohol use, opioid use, and their co-use before and after surgery. First, desires and intentions to use opioids for postoperative pain management varied widely, even before opioids were prescribed. Second, some participants described alcohol as a preferred pain management strategy. Third, participants held a range of beliefs about the risks and benefits of alcohol and opioid co-use.ConclusionsAppropriate assessment of beliefs and intentions regarding opioid and alcohol use could help identify patients most vulnerable to new opioid problems and unhealthy alcohol use in the context of perioperative surgical pain. These findings have important implications for perioperative pain management.

BackgroundIn the United States, the criminalization and stigmatization of drug use and sex work contribute to infectious disease transmission and healthcare disengagement. People who inject drugs (PWID) and engage in sex work experience exacerbated HIV risk. In the context of the ongoing HIV and overdose epidemics little research describes why PWID engage in sex work and its relative HIV risk. To inform intervention needs, we aimed to create a typology of sex work among PWID with a focus on HIV risk and healthcare utilization behaviours.MethodsWe drew from in-depth interviews conducted across Massachusetts and Rhode Island from 2016-2019. Participants were ≥18 years old and self-reported past-month injection drug use and HIV-negative status. Using data from individuals reporting sex work experience (n=33/78), we utilized the framework method to develop a typology of perspectives on sex work engagement and attributes pertaining to HIV risk and healthcare utilization behaviours.ResultsWe uncovered varying perspectives on sex work and associated HIV risks and prevention needs. A typology included three groups who viewed their sex work engagement as a (1) consistent job, (2) income supplement, or (3) survival method to abate withdrawal symptoms. The first group described more consistent sexual and injection behaviours to mitigate HIV risk than the second group. The third group appeared particularly vulnerable to HIV, describing inconsistent condom use and frequent sharing of injection equipment, low healthcare utilization, and limited disclosure of sex work and injection drug use to healthcare providers.ConclusionFindings highlight distinct perspectives on sex work among PWID involved in it and corresponding perceptions of HIV risk and healthcare utilization behaviours. Understanding the nuances in sex work engagement among PWID can inform interventions to prevent infectious disease transmission, including efforts to further connect this marginalized population to harm reduction, health, and low barrier opioid treatment services.

Engagement in HIV care and a high level of antiretroviral therapy (ART) adherence for people living with HIV is crucial to treatment success and can minimize the population burden of the disease. Despite this, there is a critical gap in HIV prevention science around the development of interventions for serodiscordant male couples. This paper reports on the results of a randomized controlled trial to assess the efficacy of Stronger Together, a dyadic counseling intervention aimed at increasing engagement in and optimizing HIV care among serodiscordant male couples in Atlanta, GA, Boston, MA, and Chicago, IL. Between 2014 and 2017, 159 male serodiscordant couples (total N = 318) in Atlanta, GA, Boston, MA, and Chicago, IL were enrolled and equally randomized to either the Stronger Together intervention arm (a three-session dyadic intervention involving HIV testing and adherence counseling) or a standard of care (SOC) control arm. Couples completed individual study assessments via an audio computer assisted self-interviewing (ACASI) system at baseline, 6, 12 and 18 months. Primary outcomes included being prescribed and currently taking ART, and fewer missed doses of ART in the past 30 days; because the trial was not powered to examine viral suppression, we examined this as an exploratory outcome. Longitudinal data analysis was by an intention-to-treat approach. Participants ages ranged from 18 to 69 (mean = 35.9), and are predominantly white (77.5%), and college educated (68.4% earned a college degree or higher). Participants randomized to the Stronger Together arm had a significantly greater odds of being prescribed and currently taking ART over time than those in the SOC arm (at 12 months OR 2.75, 95%CI 1.35-4.67, p-value 0.020, and at 18 months OR 2.91, 95%CI 1.61-4.88, p-value 0.013). Similarly, those in the Stronger Together arm had a significantly lower odds of missing a dose of ART in the past 30 days over time compared to those in the SOC arm (at 12 months OR 0.28, 95%CI 0.09-0.81, p-value 0.019, and at 18 months OR 0.25, 95%CI 0.07-0.82, p-value 0.023). Among male couples in serodiscordant relationships, the Stronger Together intervention resulted in significantly improved HIV treatment outcomes at both 12 and 18 months of follow-up. This trial is the first to date to demonstrate evidence of efficacy for a dyadic counseling intervention and has the potential to fill a critical gap in secondary HIV prevention interventions for serodiscordant male couples.

Purpose of reviewRecent HIV outbreaks among people who use drugs (PWUD) necessitate additional HIV prevention tools. Pre-exposure prophylaxis (PrEP) is highly efficacious yet uptake among PWUD remains exceedingly low. To address multilevel, complex barriers to PrEP use among PWUD, a range of intervention strategies are needed.Recent findingsThe literature on interventions to optimize PrEP use among PWUD is nascent, comprising small pilots and demonstration projects in early phases of intervention development. Initial studies suggest that structural, healthcare, interpersonal, and individual-level interventions can improve PrEP use for PWUD, and a number of efficacy trials are underway. Future studies are needed to optimize the use of new PrEP modalities (e.g., injectable PrEP), simultaneously target multilevel challenges to PrEP use, and evaluate the integration of PrEP into other service settings and substance use treatment modalities.

BackgroundEfforts to address opioid-involved overdose fatalities have led to widespread implementation of various initiatives to taper (i.e., reduce or discontinue) opioid prescriptions despite a limited understanding of patients' experience.MethodsFrom 2019-2020, we recruited patients with chronic, non-cancer pain who had undergone a reduction in opioid daily dosage of ≥50 % in the past two years at Boston Medical Center or Michigan Medicine. Participants completed semi-structured interviews exploring health history, opioid use, and taper experiences. Inductive analysis, guided by theoretical conceptualizations of structural stigma, identified emergent themes.ResultsAmong 41 participants, three elements of structural stigma were identified across participants' lives. First, participants identified themselves as overlooked subjects of the U.S. opioid crisis, who experienced overprescribing, subsequent stigmatization and surveillance of opioid use (e.g., toxicology screening, "pill counts"), and various tapering initiatives. Second, during the course of pain treatment, participants felt stigmatized and invalidated by cultural norms linking chronic pain to stereotypes of acting disingenuously (e.g., "drug-seeking"). Finally, during and after tapers, institutional policies and programs further increased participants' feelings of marginalization, producing multiple unintended consequences, including reduced access to medical care and feeling "orphaned by the system."ConclusionsOpioid tapers may exacerbate the social production and burden of stigma among patients with chronic pain, especially when processes are perceived to invalidate pain, endorse stereotypes, and label previously effective, acceptable treatment as inappropriate. Findings highlight how various tapering initiatives reinforce the devalued status of people living with chronic pain while also reducing patients' wellbeing and confidence in medical systems.

BackgroundThe estimated 2.2 million people who inject drugs (PWID) in the USA experience significant gaps in preventive healthcare and a high burden of infectious, psychiatric, and other chronic diseases. Many PWID rely on emergency medical services, which are costly and not designed to deliver preventive services, manage chronic conditions, or address social needs.ObjectiveThe objective of this study was to explore barriers and facilitators to primary care utilization from the perspectives of PWID in New England, a region highly affected by the overdose crisis.DesignParticipants completed semi-structured qualitative interviews exploring substance use and healthcare utilization patterns.ParticipantsWe recruited 78 PWID through community-based organizations (e.g., syringe service programs) in 16 urban and non-urban communities throughout Massachusetts and Rhode Island.ApproachThematic analysis identified barriers and facilitators to primary care utilization at the individual, interpersonal, and systemic levels.Key resultsAmong 78 PWID, 48 described recent primary care experiences; 33 had positive experiences and 15 described negative experiences involving discrimination or mistrust. Individual-level barriers to primary care utilization included perceived lack of need and competing priorities (e.g., avoiding opioid withdrawal, securing shelter beds). Interpersonal-level barriers included stigma and perceived low quality of care for PWID. Systemic-level barriers included difficulty navigating healthcare systems, inadequate transportation, long wait times, and frequent provider turnover. Participants with positive primary care experiences explained how appointment reminders, flexible hours, addiction medicine-trained providers, case management services, and transportation support facilitated primary care utilization and satisfaction.ConclusionsFindings regarding the multilevel barriers and facilitators to accessing primary care among PWID identify potential targets for programmatic interventions to improve primary care utilization in this population. Based on these findings, we make recommendations for improving the engagement of PWID in primary care as a means to advance individual and public health outcomes.

BackgroundPeople who inject drugs (PWID) are at increased risk for HIV acquisition and could benefit from antiretroviral pre-exposure prophylaxis (PrEP). However, PrEP has been underutilized in this population, and PrEP adherence intervention needs are understudied.MethodsTo inform PrEP intervention development, we reviewed evidence on antiretroviral therapy (ART) adherence among HIV-infected PWID. Guided by a behavioral model of healthcare utilization and using the PICOS framework, we conducted a systematic review in four electronic databases to identify original research studies of ART adherence in HIV-infected PWID in the United States and Canada between Jan 1, 2006-Dec 31, 2016. We synthesized and interpreted findings related to developing recommendations for PrEP adherence interventions for PWID.ResultsAfter excluding 618 duplicates and screening 1049 unique records, we retained 20 studies of PWID (mean n = 465) with adherence-related outcomes (via pharmacy records: n = 9; self-report: n = 8; biological markers: n = 5; electronic monitoring: n = 2). Predisposing factors (patient-level barriers to adherence) included younger age, female sex, and structural vulnerability (e.g., incarceration, homelessness). Enabling resources (i.e., facilitators) that could be leveraged or promoted by interventions included self-efficacy, substance use treatment, and high-quality patient-provider relationships. Competing needs that require specific intervention strategies or adaptations included markers of poor physical health, mental health comorbidities (e.g., depression), and engagement in transactional sex.ConclusionsHIV treatment adherence research carries important lessons for efforts to optimize PrEP adherence among PWID. Despite limitations, this systematic review suggests that strategies are needed to engage highly vulnerable and marginalized sub-groups of this underserved population (e.g., younger PWID, women who inject drugs) in PrEP adherence-related research and programming.

BackgroundHepatitis C virus (HCV) infection is increasingly prevalent among people who inject drugs (PWID) in the context of the current US opioid crisis. Although curative therapy is available and recommended as a public health strategy, few PWID have been treated. We explore PWID narratives that explain why they have not sought HCV treatment or decided against starting it. We then compare these narratives to evidence-based and guideline-concordant information to better enable health, social service, harm reduction providers, PWID, and other stakeholders to dispel misconceptions and improve HCV treatment uptake in this vulnerable population.MethodsWe recruited HIV-uninfected PWID (n = 33) through community-based organizations (CBOs) to participate in semi-structured, in-depth qualitative interviews on topics related to overall health, access to care, and knowledge and interest in specific HIV prevention methods.ResultsIn interviews, HCV transmission and delaying or forgoing HCV treatment emerged as important themes. We identified three predominant narratives relating to delaying or deferring HCV treatment among PWID: (1) lacking concern about HCV being serious or urgent enough to require treatment, (2) recognizing the importance of treatment but nevertheless deciding to delay treatment, and (3) perceiving that clinicians and insurance companies recommend that patients who currently use or inject drugs should delay treatment.ConclusionsOur findings highlight persistent beliefs among PWID that hinder HCV treatment utilization. Given the strong evidence that treatment improves individual health regardless of substance use status while also decreasing HCV transmission in the population, efforts are urgently needed to counter the predominant narratives identified in our study. We provide evidence-based, guideline-adherent information that counters the identified narratives in order to help individuals working with PWID to motivate and facilitate treatment access and uptake. An important strategy to improve HCV treatment initiation among PWID could involve disseminating guideline-concordant counternarratives to PWID and the providers who work with and are trusted by this population.

IntroductionFemale and male sex workers experience heightened vulnerability to HIV and other health harms that are compounded by substance use, physical and sexual violence, and limited access to health services. In Kisumu, Kenya, where sex work is widespread and substance use is a growing public health concern, offering pre-exposure prophylaxis (PrEP) for HIV prevention could help curtail the HIV epidemic. Our study examines "syndemics," or mutually reinforcing epidemics of substance use, violence and HIV, in relation to PrEP acceptability and feasibility among female and male sex workers in Kenya, one of the first African countries to approve PrEP for HIV prevention.MethodsFrom 2016 to 2017, sex workers in Kisumu reporting recent alcohol or drug use and experiences of violence participated in qualitative interviews on HIV risk and perspectives on health service needs, including PrEP programming. Content analysis identified themes relating to PrEP knowledge, acceptability, access challenges and delivery preferences.ResultsAmong 45 female and 28 male sex workers, median age was 28 and 25 respectively. All participants reported past-month alcohol use and 91% of women and 82% of men reported past-month drug use. Violence was pervasive, with most women and men reporting past-year physical (96% women, 86% men) and sexual (93% women, 79% men) violence. Concerning PrEP, interviews revealed: (1) low PrEP knowledge, especially among women; (2) high PrEP acceptability and perceived need, particularly within syndemic contexts of substance use and violence; and (3) preferences for accessible, non-stigmatizing PrEP delivery initiatives designed with input from sex workers.ConclusionsThrough a syndemic lens, substance use and violence interact to increase HIV vulnerability and perceived need for PrEP among female and male sex workers in Kisumu. Although interest in PrEP was high, most sex workers in our sample, particularly women, were not benefiting from it. Syndemic substance use and violence experienced by sex workers posed important barriers to PrEP access for sex workers. Increasing PrEP access for sex workers will require addressing substance use and violence through integrated programming.

Utilizing mixed methods, we examined intimate partner violence (IPV) behaviors among 428 female sex workers (FSWs) who use drugs and their noncommercial male partners in Tijuana and Ciudad Juarez, Mexico. Half of all participants reported perpetrating and experiencing at least one type of IPV behavior in the past year. In interviews, drug use emerged as an important theme associated with IPV behaviors, and we found men and women differed in their motivations for engaging in IPV behaviors. Findings highlight how gender and power are interlinked with and may exacerbate drug use and IPV behaviors among marginalized populations.

Up to two-thirds of new cases of HIV transmission between gay, bisexual and other men who have sex with men in the USA are attributed to primary relationships. Understanding the relationship dynamics and sexual agreements of male-male couples can provide insight into HIV transmission patterns and prevention needs in this population. The daily use of antiretroviral pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV, but its negotiation and use within social and intimate relationship contexts remain understudied. We conducted semi-structured qualitative interviews with 20 male couples (n = 40 men) in which at least one partner was either using or in the process of initiating PrEP. Congruent with a theoretical focus on social theories of relationships and negotiated risk, couples were interviewed about relationship dynamics, trust, communication and sexual health practices, including their perception and use of PrEP. Overall, we found that couples showed heightened trust and communication when establishing open, sexual agreements and demonstrated high awareness of sexual risks and health practices in the context of PrEP use. This study demonstrates how understanding relationship dynamics can better inform HIV prevention and sexual health promotion efforts for male couples at risk of HIV.

ObjectiveTo describe the frequency of being partnered and having an HIV-negative partner, and whether this differed by gender, among a cohort of persons living with HIV (PLWH) who have ever injected drugs; to describe awareness of HIV pre-exposure prophylaxis (PrEP) and perceived partner interest in PrEP.SettingSecondary analyses of an observational cohort study of PLWH who have ever injected drugs in St. Petersburg, Russia.MethodsPrimary outcomes were 1) being partnered and 2) being in a serodiscordant partnership. The main independent variable was gender. Multivariable GEE logistic regression models were fit for binary outcomes, adjusted for age, income, education, and recent opioid use. Descriptive analyses were performed for partners' HIV status, substance use, sex risk behaviors, and awareness of PrEP for a subset of participants.ResultsAt baseline, 50% (147/296) reported being in a partnership, and of those, 35% were in a serodiscordant partnership. After adjustment, women had significantly higher odds of being partnered compared to men (aOR = 3.12; 95% CI: 1.77, 5.51), but there were no significant gender differences in the odds of being in a serodiscordant partnership (aOR = 0.58; 95% CI: 0.27, 1.24). Among a sub-sample of participants queried (n = 56), 25% were aware of PrEP for prevention of sexual HIV transmission and 14% for prevention of injection-related transmission.ConclusionAlthough half of our sample were partnered and one third of these partnerships were serodiscordant, PrEP awareness was low. Substantial opportunities for HIV prevention exist among PLWH who have ever injected drugs in Russia and their HIV-negative partners. Given the high proportion of HIV-negative partners among this ART-naïve sample, efforts to address the associated inherent risks, such as couples-based interventions, are needed to increase condom use, PrEP awareness, or uptake of other HIV-prevention modalities (e.g., ART for the HIV-positive partner).
