RESUMO
PrEP is an HIV prevention option that could benefit substance-involved women, a high-risk population with low PrEP uptake. Little is known about their interest in PrEP. This qualitative study used in-depth interviews to examine PrEP willingness, barriers, and facilitators among 16 women in outpatient psychosocial substance use treatment, methadone, and/or harm reduction/syringe programs in NYC. All expressed willingness to use PrEP, but only during periods of perceived risk. Women perceived themselves to be at high risk for HIV when engaging in active substance use and/or transactional sex. They perceived themselves to be at low risk and therefore unmotivated to take PrEP when abstinent from these activities. Paradoxically, a major barrier to using PrEP was anticipated interference from substance use and transactional sex, the very same activities that create a perception of risk. Facilitators of PrEP use included perceptions of it as effortless (as opposed to barrier methods during sex) and effective, safe, and accessible. Other barriers included fear of stigma and doubts about adhering daily. Recommendations for best PrEP implementation practices for substance-involved women included tailored and venue-specific PrEP information and messaging, PrEP discussion with trusted medical providers, and on-site PrEP prescription in substance use treatment and harm reduction programs.
RESUMEN: PrEP es una opción de prevención de VIH que puede beneficiar a las mujeres que consumen sustancias, una población de alto riesgo con baja aceptación de la PrEP, pero poco se sabe de su interés en la PrEP. Este estudio cualitativo utilizó entrevistas para examinar el interés en tomar la PrEP y las barreras y los facilitadores del uso de la PrEP entre 16 mujeres en tratamiento por el uso de sustancias en clínicas ambulatorias, clínicas metadonas, o programas de reducción de daños en la ciudad de Nueva York, Estados Unidos. Todas las participantes expresaron su disposición a usar PrEP, pero solo durante períodos de riesgo percibido (por ejemplo, tiempos de uso de sustancias activas y/o sexo transaccional). Paradójicamente, una barrera importante para el uso de PrEP fue la interferencia anticipada por el uso de sustancias y el sexo transaccional, las mismas actividades que crean una percepción de riesgo. Los facilitadores incluyeron percepciones de PrEP como sin esfuerzo durante las relaciones sexuales, efectiva, segura, y accesible. Otras barreras incluyeron el miedo del estigma y dudas sobre la adherencia diaria. Las recomendaciones para las mejores prácticas de implementar la PrEP para mujeres que consumen sustancias incluyeron información y mensajes de PrEP personalizados y específicos del lugar, discusión de PrEP con proveedores médicos confiables, y prescripción de PrEP en el sitio en programas de tratamiento y reducción de daños por uso de sustancias.

This study explored factors associated with durable viral suppression (DVS) among two groups of people living with HIV (PLWH) and problem substance use in the context of universal antiretroviral treatment initiation. Participants (N = 99) were recruited between 2014-2017 from public sexual health clinics [SHC] and a hospital detoxification unit [detox]). DVS (NYC HIV surveillance registry) was defined as two consecutive viral load tests ≤ 200 copies/mL, ≤ 90 days apart, with all other viral loads suppressed over 12 or 18 months. Detox participants were significantly older, with more unstable housing/employment, substance use severity, and longer-term HIV vs. SHC participants. Older age, opioid and stimulant use disorder were significantly associated with lower odds of DVS, while fulltime employment and stable housing were significantly associated with higher odds of DVS at 12-month follow-up. Patterns held at 18-month follow-up. Co-located substance use and HIV services, funding for supportive housing, and collaborative patient-provider relationships could improve DVS among populations with the syndemic of problem substance use, poverty, and long-term HIV.

According to 2012 universal ART guidelines, as part of "treatment as prevention" (TasP), all people living with HIV (PLWH) should immediately initiate antiretroviral therapy post-diagnosis to facilitate viral suppression. PLWH who are virally suppressed have no risk of sexually transmitting HIV. This study used descriptive analysis of quantitative data (N = 99) and thematic analysis of qualitative interviews (n = 36) to compare participants recruited from a hospital-based detoxification (detox) unit, largely diagnosed with HIV pre-2012 (n = 63) vs. those recruited from public, urban sexual health clinics (SHCs), mainly diagnosed in 2012 or later (n = 36). Detox participants were significantly more knowledgeable than SHC participants about HIV treatment, except regarding TasP. SHC participants' desire for rapid linkage to care and ART initiation was in line with 2012 universal ART guidelines and TasP messaging regarding viral suppression. More targeted messaging to PLWH pre-2012 could ensure that all PLWH benefit from scientific advances in HIV treatment.

We tested the hypothesis that an updated "Break the Cycle" (BtC) intervention, based in social cognitive theory and motivational interviewing, would reduce the likelihood that current persons who inject drugs (PWID) would assist persons who do not inject drugs (non-PWID) with first injections in Tallinn, Estonia and Staten Island, New York City. 402 PWID were recruited, a baseline interview covering demographics, drug use, and assisting non-PWID with first drug injections was administered, followed by BtC intervention. 296 follow-up interviews were conducted 6 months post-intervention. Percentages assisting with first injections declined from 4.7 to 1.3% (73% reduction) in Tallinn (p < 0.02), and from 15 to 6% (60% reduction) in Staten Island (p < 0.05). Persons assisted with first injections declined from 11 to 3 in Tallinn (p = 0.02) and from 32 to 13 in Staten Island. (p = 0.024). Further implementation research on BtC interventions is urgently needed where injecting drug use is driving HIV/HCV epidemics and areas experiencing opioid epidemics.

Injecting 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.
