The perfect storm: incarceration and the high-risk environment perpetuating transmission of HIV, hepatitis C virus, and tuberculosis in Eastern Europe and Central Asia

Prevalence, treatment, and outcomes of hepatitis C in an MDR/RR-TB trial cohort

Tuberculosis (TB) and chronic hepatitis C virus infection (HCV) remain significant global health challenges, especially in low- and middle-income countries. In Eastern Europe, a considerable percentage of multi-drug resistant (MDR) and rifampicin resistant (RR) TB populations show high HCV prevalence. Current WHO guidelines do not routinely advise HCV testing during MDR-TB treatment, despite HCV being a risk factor for drug-induced liver complications in TB patients. This study investigates the co-treatment of MDR/RR-TB and HCV, using data from the TB-PRACTECAL trial. Data were collected as part of the TB-PRACTECAL clinical trial. All participants were screened for HCV at baseline. Participants who were HCV antibody positive and those who were treated for hepatitis C with Direct Acting Antivirals (DAAs) were extracted and compared to overall cohort characteristics. The characteristics of participants concomitantly treated with direct-acting antivirals are described including hepatitis treatment outcomes and adverse events. Among 552 participants from Belarus, Uzbekistan, and South Africa, 24 (4.3%) were HCV antibody positive. Unfavourable TB treatment outcomes were noted in 106/523 (22%) of the HCV-negative, 8/18 (44%) of the HCV-seropositive, and 2/7 (29%) of HCV-confirmed participants treated with DAAs. Of the six participants who received concurrent HCV and MDR/RR TB treatment, three were cured of HCV and three had no post-treatment HCV RNA test, five completed TB treatment and one discontinued treatment due to a severe adverse reaction. Concurrent treatment of MDR-TB and HCV, including in HIV patients, showed promising outcomes with no significant adverse events. The findings support the potential benefits of integrating HCV care into MDR-TB management.

HIV and hepatitis C virus infection and co-infection among trans women in San Francisco, 2020

BACKGROUND

Transgender women (hereafter "trans women") face social marginalization, stigma, and discrimination and experience a high burden of HIV. More recently, trans women have been identified as having a high risk for hepatitis C (HCV) infection. The interaction between these two diseases and the risks for HIV/HCV co-infection among trans women are understudied.

OBJECTIVE

To characterize epidemiological, behavioral, and socio-structural interactions between HIV and HCV infections among trans women.

METHODS

This cross-sectional study examined data from a community-based survey of trans women in San Francisco recruited through respondent-driven sampling (RDS) in 2019/2020. Face-to-face interviews collected data on demographics, medical history, drug injection practices, sexual behavior, and socio-structural factors (e.g., poverty, housing insecurity, incarceration, social support). HIV and HCV antibodies were detected using oral fluid rapid tests and prior diagnosis and treatment were collected by self-report. Blood specimens were collected to confirm antibodies using ELISA. Multinomial logistic regression analysis characterized factors associated with HIV infection alone, HCV infection alone, and HIV/HCV co-infection compared to neither infection.

RESULTS

Among 201 trans women recruited, HIV prevalence was 42.3%; HCV infection by history or current seroprevalence was 28.9%; evidence for both HIV and HCV infection was present for 18.9%. Two-thirds of trans women (67.2%) had been incarcerated; 30.8% had ever injected drugs. History of injection drug use and receiving emotional support from family were factors found in common for HIV infection, HCV infection, and HIV/HCV co-infection compared to no infection. Having a sexual partner who injects drugs was associated with HIV infection alone. Not lacking care due to cost and older age were associated with co-infection. Older age was also associated with HCV infection. Of trans women with HIV infection, 91.8% had accessed HIV care, whereas only 62% with HCV had accessed some form of care.

CONCLUSIONS

Our study found high levels of HIV, HCV, and HIV/HCV co-infection among trans women in San Francisco. We found common associations between HIV and HCV through injection practices and emotional support, but having a sexual partner who injects drugs was not associated with HCV infection alone or co-infection. We note a substantial gap in the treatment of HCV for trans women, including those in HIV care, that needs to be urgently addressed.

From conceptualising to modelling structural determinants and interventions in HIV transmission dynamics models: a scoping review and methodological framework for evidence-based analyses

BACKGROUND

Including structural determinants (e.g. criminalisation, stigma, inequitable gender norms) in dynamic HIV transmission models is important to help quantify their population-level impacts and guide implementation of effective interventions that reduce the burden of HIV and inequalities thereof. However, evidence-based modelling of structural determinants is challenging partly due to a limited understanding of their causal pathways and few empirical estimates of their effects on HIV acquisition and transmission.

METHODS

We conducted a scoping review of dynamic HIV transmission modelling studies that evaluated the impacts of structural determinants, published up to August 28, 2023, using Ovid Embase and Medline online databases. We appraised studies on how models represented exposure to structural determinants and causal pathways. Building on this, we developed a new methodological framework and recommendations to support the incorporation of structural determinants in transmission dynamics models and their analyses. We discuss the data and analyses that could strengthen the evidence used to inform these models.

RESULTS

We identified 17 HIV modelling studies that represented structural determinants and/or interventions, including incarceration of people who inject drugs (number of studies [n] = 5), violence against women (n = 3), HIV stigma (n = 1), and housing instability (n = 1), among others (n = 7). Most studies (n = 10) modelled exposures dynamically. Almost half (8/17 studies) represented multiple exposure histories (e.g. current, recent, non-recent exposure). Structural determinants were often assumed to influence HIV indirectly by influencing mediators such as contact patterns, condom use, and antiretroviral therapy use. However, causal pathways' assumptions were sometimes simple, with few mediators explicitly represented in the model, and largely based on cross-sectional associations. Although most studies calibrated models using HIV epidemiological data, less than half (7/17) also fitted or cross-validated to data on the prevalence, frequency, or effects of exposure to structural determinants.

CONCLUSIONS

Mathematical models can play a crucial role in elucidating the population-level impacts of structural determinants and interventions on HIV. We recommend the next generation of models reflect exposure to structural determinants dynamically and mechanistically, and reproduce the key causal pathways, based on longitudinal evidence of links between structural determinants, mediators, and HIV. This would improve the validity and usefulness of predictions of the impacts of structural determinants and interventions.

Using nominal group technique with people who are incarcerated in Canadian federal prisons to identify barriers and solutions to improving Prison Needle Exchange Program uptake

BACKGROUND

Prison needle exchange programs (PNEPs) are a critical component for harm reduction in prisons. Little is known about the PNEP access barriers for people who are incarcerated, but the low uptake in the Canadian program highlights these constraints. We aimed to identify the barriers and potential solutions for increasing PNEP coverage in the nine Canadian federal prisons where they operate.

METHODS

Eighteen focus groups were conducted in nine prisons using nominal group technique (NGT) with two stakeholders: peer advocates and people who use or identified as potential users of the PNEP. NGT uses a round-robin technique followed by generating a list of barriers to PNEP enrolment within their prison. Participants then allocated votes to rank the highest priority barriers, followed by an identical process to generate solutions to address the top three barriers. Interview transcripts describing participant narratives during this process were de-identified and coded to generated themes. Barriers and solutions receiving >10 % of votes within respective participant groups, alongside associated narratives, are discussed more fully.

RESULTS

Fear of repercussions due to drug use, lack of confidentiality, and fear of being targeted and sanctioned by correctional authorities were perceived by both stakeholder groups as the top barriers inhibiting PNEP enrolment. Stigma (peer advocates) and the application process for the program (PNEP users) were also ranked as a priority. Proposed solutions included education and external oversight of PNEP (i.e., not via correctional officers) by both groups. Peer advocates regarded improving participant confidentiality and a supervised/safe injection site as potential enablers for program participation, while PNEP users identified wrap-around services as likely to improve access.

CONCLUSION

Barriers to increasing PNEP coverage in Canadian federal prisons proposed by participants highlight the importance of trust and perceived repercussions surrounding program participation. These barriers and proposed solutions highlight a need for changes in implementation to PNEP delivery if the potential health benefits of PNEPs are to be realised.

Understanding hepatitis C virus (HCV) health literacy and educational needs among people in prison to enhance HCV care in prisons

BACKGROUND

Hepatitis C virus (HCV) is a significant concern within prison populations. Provision of HCV testing and treatment for people in prison is expanding and a key component of global elimination efforts. Despite growing service availability, several challenges remain in HCV testing and treatment engagement during incarceration. The PIVOT study demonstrated that a 'one-stop-shop' intervention (point-of-care HCV RNA testing, Fibroscan®, nurse-led clinical assessment, and fast-tracked direct-acting antiviral prescription) enhanced HCV testing and treatment at a reception prison in Australia. Utilising Squier et al's Health Literacy Skills Framework, this analysis aimed to understand HCV health literacy and educational needs among people at a reception prison in Australia.

METHODS

Semi-structured interviews were conducted with twenty-four male PIVOT study participants. Purposive sampling ensured comparable representation of those with: 1) prior HCV testing history (standard pathology / no prior testing), and 2) injecting drug use history (IDU; ever / never).

RESULTS

Varied HCV health literacy levels and educational needs were evident amongst people in prison. Whilst those with multiple incarceration episodes and IDU history (prior knowledge) appeared to have stronger HCV health literacy than those without, substantial gaps in HCV health literacy were evident. Knowledge of HCV transmission risks in prison was high, and most understood the importance of HCV testing and treatment in prison (comprehension), but ability to engage with HCV testing and treatment services, participation in safe injecting behaviours (health-related behaviours), and knowledge of re-infection and re-treatment, within the context of the prison environment, were suboptimal. There was a general desire for increased HCV education in prison.

CONCLUSION

Gaps in HCV health literacy among people in prison were evident, indicating opportunities for improvement. A targeted HCV education program for people in prison, addressing the gaps identified in this analysis, may enhance HCV testing, treatment, and prevention by fostering stronger HCV health literacy among people in prison.

Using nominal group technique to identify perceived barriers and facilitators to improving uptake of the Prison Needle Exchange Program in Canadian federal prisons by correctional officers and healthcare workers

BACKGROUND

Elimination of bloodborne viruses including HIV and hepatitis C virus from prisons requires high coverage of evidence-based interventions that prevent bloodborne virus transmission, including needle and syringe programs. Canada launched a Prison Needle Exchange Program (PNEP) in nine federal prisons in 2018; however, uptake among people who inject drugs in prison remains low. We aimed to explore barriers and facilitators to improving PNEP uptake identified by correctional officers and healthcare workers.

METHODS

Participants from nine federal prisons with PNEP completed focus groups using nominal group technique, a rapid mixed-method consensus strategy. Responses were generated, rank-ordered, and prioritized by each stakeholder group. We identified the highest-ranking responses (≥10 % of the overall votes) to questions about barriers and facilitators to PNEP uptake.

RESULTS

Between September 2023 and February 2024, 16 focus groups were conducted with 118 participants (n = 51 correctional officers; n = 67 healthcare workers). Among correctional officers, the top perceived barriers were bullying from peers (22 %), fear of being targeted by correctional officers (14 %), and fear of repercussions due to drug use (13 %). The top facilitators were safe injection sites (30 %), provision of wrap-around services (16 %), and education of correctional officers (10 %). Among healthcare workers, the top perceived barriers were lack of confidentiality (16 %), fear of being targeted by correctional officers (12 %), and a long and complex application process (11 %). The top facilitators were education of correctional officers (29 %), delivery of PNEP by an external provider (15 %), automatic approval for participation in the PNEP (13 %), and safe injection sites (12 %).

CONCLUSION

Multiple modifiable barriers and solutions to improving PNEP uptake in Canadian federal prisons were identified by correctional employees. Both participant groups identified the potential for safe injection sites and education to correctional officers as enabling PNEP uptake. These data will inform Canadian efforts to improve engagement and to expand PNEP coverage.

Seroepidemiological Investigation of Hepatitis B and C Prevalence and Associated Factors Among People in Custody at Zahedan Central Prison

BACKGROUND

On a global scale, approximately 350 million are affected by hepatitis B, and 71 million by hepatitis C. People in custody face elevated risks for these infections. The prevalence and risk factors in Iranian prisons are insufficiently documented. The principal objective of this study was to ascertain the prevalence of hepatitis B and C, coupled with the identification of pertinent influencing factors, within the confines of Zahedan central prison, situated in the southeastern region of Iran.

METHODS

In 2019, we conducted an analytical cross-sectional study involving 407 people in custody, using stratified random sampling. To definitively diagnose hepatitis C virus (HCV) infection (P<0.05), a checklist developed by the researchers, along with enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) techniques, were employed.

RESULTS

This study comprised 406 participants (96.3% male) with a median age of 32 years (27-38). Approximately 62% were married, and a substantial proportion of the participants had low education levels (47%), unemployment (64%), and belonged to the Baloch ethnicity (64%). The overall prevalence of hepatitis C and B infections was 2.7% and 10.6%, respectively. Tattooing (adjusted odds ratio [AOR]: 2.07, 95% CI: 1.9-4.5) and marriage (AOR: 1.78, 95% CI: 1.05-3.04) were identified as risk factors for hepatitis B. Moreover, hepatitis C showed a statistically significant association with a family history of hepatitis B and C (AOR: 3.31, 95% CI: 3.93-24.64) and intravenous (IV) drug use (AOR: 7.01, 95% CI: 1.52-32.78) according to the multivariable logistic regression analysis.

CONCLUSION

The prevalence of hepatitis B and C was higher among people in custody in Zahedan central prison. Consequently, targeted interventions are vital to address and reduce viral hepatitis burden in custodial settings.

Higher methadone dose at time of release from prison predicts linkage to maintenance treatment for people with HIV and opioid use disorder transitioning to the community in Malaysia

BACKGROUND

Incarcerated people with HIV and opioid-dependence often experience poor post-release outcomes in the absence of methadone maintenance treatment (MMT). In a prospective trial, we assessed the impact of methadone dose achieved within prison on linkage to MMT after release.

METHODS

From 2010 to 2014, men with HIV (N = 212) and opioid dependence before incarceration were enrolled in MMT within 6 months of release from Malaysia's largest prison and followed for 12-months post-release. As a prospective trial, allocation to MMT was at random and later by preference design (predictive nonetheless). MMT dosing was individually targeted to minimally achieve 80 mg/day. Time-to-event analyses were conducted to model linkage to MMT after release.

FINDINGS

Of the 212 participants allocated to MMT, 98 (46 %) were prescribed higher dosages (≥80 mg/day) before release. Linkage to MMT after release occurred in 77 (36 %) participants and significantly higher for those prescribed higher dosages (46% vs 28 %; p = 0.011). Factors associated with higher MMT dosages were being married, on antiretroviral therapy, longer incarceration periods, having higher levels of depression, and methadone preference compared to randomization. After controlling for other variables, being prescribed higher methadone dosage (aHR: 2.53, 95 %CI: 1.42-4.49) was the only independent predictor of linkage to methadone after release.

INTERPRETATION

Higher doses of methadone prescribed before release increased the likelihood of linkage to MMT after release. Methadone dosing should be introduced into international guidelines for treatment of opioid use disorder in prisons and further post-release benefits should be explored.

Mental and physical health morbidity among people in prisons: an umbrella review

BACKGROUND

People who experience incarceration are characterised by poor health profiles. Clarification of the disease burden in the prison population can inform service and policy development. We aimed to synthesise and assess the evidence regarding the epidemiology of mental and physical health conditions among people in prisons worldwide.

METHODS

In this umbrella review, five bibliographic databases (Web of Science, PubMed, PsycINFO, Embase, and Global Health) were systematically searched from inception to identify meta-analyses published up to Oct 31, 2023, which examined the prevalence or incidence of mental and physical health conditions in general prison populations. We excluded meta-analyses that examined health conditions in selected or clinical prison populations. Prevalence data were extracted from published reports and study authors were contacted for additional information. Estimates were synthesised and stratified by sex, age, and country income level. The robustness of the findings was assessed in terms of heterogeneity, excess significance bias, small-study effects, and review quality. The study protocol was pre-registered with PROSPERO, CRD42023404827.

FINDINGS

Our search of the literature yielded 1909 records eligible for screening. 1736 articles were excluded and 173 full-text reports were examined for eligibility. 144 articles were then excluded due to not meeting inclusion criteria, which resulted in 29 meta-analyses eligible for inclusion. 12 of these were further excluded because they examined the same health condition. We included data from 17 meta-analyses published between 2002 and 2023. In adult men and women combined, the 6-month prevalence was 11·4% (95% CI 9·9-12·8) for major depression, 9·8% (6·8-13·2) for post-traumatic stress disorder, and 3·7% (3·2-4·1) for psychotic illness. On arrival to prison, 23·8% (95% CI 21·0-26·7) of people met diagnostic criteria for alcohol use disorder and 38·9% (31·5-46·2) for drug use disorder. Half of those with major depression or psychotic illness had a comorbid substance use disorder. Infectious diseases were also common; 17·7% (95% CI 15·0-20·7) of people were antibody-positive for hepatitis C virus, with lower estimates (ranging between 2·6% and 5·2%) found for hepatitis B virus, HIV, and tuberculosis. Meta-regression analyses indicated significant differences in prevalence by sex and country income level, albeit not consistent across health conditions. The burden of non-communicable chronic diseases was only examined in adults aged 50 years and older. Overall, the quality of the evidence was limited by high heterogeneity and small-study effects.

INTERPRETATION

People in prisons have a specific pattern of morbidity that represents an opportunity for public health to address. In particular, integrating prison health within the national public health system, adequately resourcing primary care and mental health services, and improving linkage with post-release health services could affect public health and safety. Population-based longitudinal studies are needed to clarify the extent to which incarceration affects health.

Barriers and advocacy needs for hepatitis C services in prisons: Informing the prisons hepatitis C advocacy toolkit

BACKGROUND

Carceral settings are a key focus of the 2030 WHO global hepatitis C virus (HCV) elimination goals. Despite this, access to HCV testing and treatment services in prisons remains low globally, limiting opportunities to achieve these goals. Advocacy efforts are needed to address service inequities and mobilise support for enhanced HCV programs in prisons globally. INHSU Prisons, a special interest group of the International Network on Health and Hepatitis in Substance Users (INHSU) is developing a Prisons HCV Advocacy Toolkit to address this need. Here we present findings of a mixed study to inform the development of the Toolkit.

METHODS

The aim of this study was to inform the development of the Toolkit, including understanding barriers for scaling up prison-based HCV services globally and advocacy needs to address these. An online survey (n = 181) and in-depth interviews (n = 25) were conducted with key stakeholders from countries of different economic status globally. Quantitative data were statistically analysed using R Studio and qualitative data were analysed thematically. The data sets were merged using a convergent design.

RESULTS

Key barriers for enhanced prison-based HCV services included lack of political will and action, lack of prison-based healthcare resources, and poor awareness about HCV and the importance of prison-based HCV services. These findings underscore how advocacy efforts are needed to motivate policymakers to prioritise HCV healthcare in prisons and ensure funds are available for services (including diagnostic tools and treatment, healthcare teams to implement services, and systems to measure their success). Advocacy resources to raise the awareness of policy makers, people working in the prison sector, and incarcerated populations were also identified as key to increasing HCV service uptake.

CONCLUSION

The Toolkit has the potential to support advocacy efforts for reaching HCV elimination targets. By understanding the advocacy needs of potential Toolkit end-users, the findings can inform its development and increase its accessibility, acceptability, and uptake for a globally diverse audience.

Status of HIV and comorbidities in refugees with HIV from Ukraine

PURPOSE

To describe the clinical characteristics of refugees with HIV from Ukraine that seek continuation of medical care in Germany.

METHODS

Fourty-six refugees with HIV that had left Ukraine between 24 February and 30 December 2022 were examined. Information on patients' history was obtained using a standardized questionnaire for clinical care. Interviews were conducted in Russian during their first clinical presentation.

RESULTS

Fourty-six persons (41 females and 5 males) were included and their mean age was 39.6 (±8.4) years. The mean time since HIV diagnosis was 8.0 (median, IQR 7.15) years and 70.3% of participants currently received tenfofovir-DF, lamividine and dolutegravir. Most refugees had an undetectable HIV viral load and their current mean CD4 T cell count was 702 (SD ± 289) per μL. Serology revealed previous hepatitis B infection in 50.4% without evidence for replication, with undetectable anti-hepatitis B surface antigen in the remaining refugees. Antibodies against hepatitis C were present in 23 refugees (50%), but only 10 patients had been diagnosed with hepatitis C previously. Five refugees had undergone successful antiviral treatment for hepatitis C. Detectable HCV-RNA was evident in nine patients (19.6%). Sixteen (38.6%) refugees had a positive tuberculosis (TB) interferon gamma release assay, and four were on TB treatment for previously diagnosed infection. One had been diagnosed with multidrug-resistant (MDR) TB, two with pre-extensively drug-resistant (pre-XDR) TB and two with XDR TB and were treated with combinations of second-line and novel agents according to WHO guidelines.

CONCLUSIONS

Based on this preliminary analysis of a not fully representative cohort, refugees with HIV from Ukraine were young, mostly healthy females highly adherent to antiretroviral therapy. The rate of transmittable co-infections urges early diagnostic evaluation and treatment.

Financial Vulnerability and Its Association with HIV Transmission Risk Behaviors Among People Who Inject Drugs in Kyrgyzstan

The Family Resource Scale (FRS) is a three-factor financial vulnerability (FV) measure. FV may impact HIV transmission risks. Cross-sectional data from 279 people who inject drugs (PWID) in Kyrgyzstan surveyed April-October 2021 was used to validate the FRS and estimate associations between FV on past 6-month injection and sexual HIV risk outcomes. The three-factor FRS reflected housing, essential needs, and fiscal independence, and had good internal reliability and structural validity. Greater cumulative, housing, and essential needs FRS scores were associated with increased relative risk on public injection (adjusted risk ratio [aRR], 95% confidence interval [95% CI]: 1.03 [1.01, 1.04]; aRR [95% CI]: 1.06 [1.02, 1.09]; aRR [95% CI]: 1.06 [1.03, 1.08], respectively, all p < 0.001) and preparing injections with unsafe water sources (aRR [95% CI]: 1.04 [1.02, 1.07]; aRR [95% CI]: 1.09 [1.04, 1.15]; aRR [95% CI]: 1.08 [1.03, 1.14], respectively, all p < 0.001). Results suggest that PWID housing- and essential needs-related FV may exacerbate injection HIV transmission risks. Reducing PWIDs' FV may enhance the HIV response in Kyrgyzstan.

Effect of incarceration and opioid agonist treatment transitions on risk of hospitalisation with injection drug use-associated bacterial infections: A self-controlled case series in New South Wales, Australia

BACKGROUND

Transitional times in opioid use, such as release from prison and discontinuation of opioid agonist treatment (OAT), are associated with health harms due to changing drug consumption practices and limited access to health and social supports. Using a self-controlled (within-person) study design, we aimed to understand if these transitions increase risks of injection drug use-associated bacterial infections.

METHODS

We performed a self-controlled case series among a cohort of people with opioid use disorder (who had all previously accessed OAT) in New South Wales, Australia, 2001-2018. The outcome was hospitalisation with injecting-related bacterial infections. We divided participants' observed days into time windows related to incarceration and OAT receipt. We compared hospitalization rates during focal (exposure) windows and referent (control) windows (i.e., 5-52 weeks continuously not incarcerated or continuously receiving OAT). We estimated adjusted incidence rate ratios (aIRR) using conditional logistic regression, adjusted for time-varying confounders.

RESULTS

There were 7590 participants who experienced hospitalisation with injecting-related bacterial infections (35% female; median age 38 years; 78% hospitalised with skin and soft-tissue infections). Risk for injecting-related bacterial infections was elevated for two weeks following release from prison (aIRR 1.45; 95%CI 1.22-1.72). Risk was increased during two weeks before (aIRR 1.89; 95%CI 1.59-2.25) and after (aIRR 1.91; 95%CI 1.54-2.36) discontinuation of OAT, and during two weeks before (aIRR 3.63; 95%CI 3.13-4.22) and after (aIRR 2.52; 95%CI 2.09-3.04) OAT initiation.

CONCLUSION

Risk of injecting-related bacterial infections varies greatly within-individuals over time. Risk is raised immediately after prison release, and around initiation and discontinuation of OAT. Social contextual factors likely contribute to excess risks at transitions in incarceration and OAT exposure.

Introducing methadone maintenance therapy into Ukrainian prisons: a qualitative study of criminal subculture, Russia's full-scale invasion, and contested methadone objects

Background

After pilot testing, methadone was newly being introduced into Ukrainian prisons in 2021 as part of a national scale-up strategy to treat opioid use disorder and prevent transmission of HIV and HCV infections. Opioid agonist therapy (OAT) scale-up in Eastern Europe and Central Asia prisons has been hampered by varying levels of influence of criminal subculture, an extralegal informal governance by a social hierarchy that operates in parallel to formal prison authorities. This study examined the socio-environmental factors influencing the uptake of methadone treatment in Ukrainian prisons, including changes that evolved during Russia's full-scale invasion of Ukraine and the displacement of people deprived of liberty (PDL) from conflict to non-conflict regions.

Methods

In-depth qualitative interviews (N = 37) were conducted from January 2021 to October 2022 in the only two Ukrainian prisons where methadone was being introduced with PDL (N = 18). These two prisons continued to provide methadone after the full-scale invasion. Former PDL (N = 4) were also interviewed and prison staff (N = 15). Interviews were audio-recorded, transcribed, and translated into English. Four authors independently reviewed, coded, and applied a phenomenological framework for data analysis, delineating themes related to criminal subculture, drug use, methadone uptake, and evolving changes during the Russian invasion.

Findings

Criminal subculture perceptions varied, with some seeing it as strongly discouraging drug use among certain groups, while others described it as a residual and weak influence from a more distant past. The influence of the subculture on methadone treatment uptake, however, was less clear. PDL and prison staff struggled to identify and articulate differences between illicit street-bought methadone, used recreationally, and medically prescribed methadone. Thus, the meaning of "methadone" varies in interpretation as it is being introduced, making it potentially conflicting for patients to opt into this evidence-based treatment. As Russia invaded Ukraine in 2022, PDL from conflict zones were transferred to non-conflict regions where methadone was being introduced. The prison environment became more enabling for PDL to start methadone as they were segregated and not subject to the existing criminal subculture's rules and lacked the social ties necessary to procure drugs illegally.

Conclusion

It appears that the criminal subculture is variable and evolving in Ukrainian prisons and appears to be impacted differently by the invasion of Russia. As methadone scale-up in prisons expands, it will be important to distinguish the meaning of methadone perpetuated negatively by the prison subculture versus that in which it is intended as a medical treatment by the formal prison authorities. The current invasion of Ukraine by Russia provides a potential disruption to alter this course.

Aligning public health and public safety: Probation as a touchpoint to identify and link patients with opioid use disorder to opioid agonist treatment

BACKGROUND

People in criminal justice settings (CJS) have high rates of opioid use disorder (OUD) and HIV. Probation is part of the CJS and congregates many individuals with high rates of mental health and substance use disorders relative to the general population; nevertheless, probation remains a major improvement to incarceration. As a steppingstone to full decarceration efforts, community supervision settings like probation can be leveraged as "touchpoints" to identify and link people with OUD (and other co-morbid conditions) to treatment and reduce criminal activity.

METHODOLOGY

To determine the feasibility of a modified screening, brief intervention and referral to treatment (SBIRT) strategy to link probationers to opioid agonist therapies (OAT) in the newly created probation system in Ukraine, we conducted a single-arm SBIRT intervention in eight probation centers in four Ukrainian administrative regions. For those screening positive for OUD, interest in OAT was assessed before and after a brief intervention. Those interested in OAT were referred to community OAT services. Participants with OUD also underwent HIV testing.

PRINCIPAL FINDINGS

Of the 1,298 consecutive individuals screened, 208 (16.0%) met criteria for opioid dependence. Of these, 122 (58.7%) enrolled in brief intervention, of which 54 (44.3%) had HIV and 14 (25.9%) of these were newly diagnosed. After the brief intervention, interest in starting OAT increased significantly from a median of 7.0 to 8.0 (P = <0.001) using a 10-point scale. Thirty (N = 30; 24.6%) of the enrolled participants initiated OAT and 21 of these (70%) were retained in treatment for 6 months.

SIGNIFICANCE

The prevalence of OUD (and HIV) is high among people in probation in Ukraine. SBIRT can identify a large number of people eligible for OAT, many of whom were willing to initiate and remain on OAT. Integrating SBIRT into probation can potentially assist with OAT scale-up and help address HIV prevention efforts.

The impact of border crossing and imprisonment on injection practices and risk of HIV and hepatitis C infection among men who inject drugs in Nepal

BACKGROUND

In Nepal, personal drug use is criminalized and among people who inject drugs (PWID), the majority of whom are men, movement across the border with India for drug procurement and use is common. Using a risk environment approach, this study examined associations between border crossing and imprisonment with respect to HIV, HCV and injection risk behavior among men who inject drugs in Nepal.

METHODS

This cross-sectional study analyzed data from 1345 participants from 14 districts across Nepal. Explanatory variables were prior imprisonment and past-month border crossing to procure or use drugs. We used multivariable logistic regression to evaluate associations between these variables and HIV, HCV, HIV/HCV co-infection and past-month injection risk behavior among PWID.

RESULTS

Over half of participants reported prior imprisonment (34.6% prior to past year, 21.6% within past year) and Indo-Nepal border crossing in the past year to use or buy drugs (31.2% sometimes, 20.8% often); over one quarter of participants (29.6%) reported both. Imprisonment prior to the past year was associated with higher odds of all outcome variables: HIV (adjusted odds ratio (aOR) 2.44, 95% confidence interval (CI) 1.29-4.59), HCV (aOR 1.51, 95% CI 1.08-2.09), HIV/HCV co-infection (aOR 3.12, 95% CI 1.58-6.14) and injection risk behavior (aOR 1.64, 95% CI 1.20-2.25). Past-year border crossing to procure or use drugs was associated with HCV (aOR 2.06, 95% CI 1.42-2.98) and injection risk behavior (aOR 1.47, 95% CI 1.04-2.10), with larger effect sizes among PWID who reported both border crossing as well as history of imprisonment.

CONCLUSION

Imprisonment and border crossing were associated with injection risk behavior and disease outcomes. These findings indicate a need to implement cross-border disease surveillance and harm reduction initiatives in the Indo-Nepal border region and in Nepali prisons.

Modeling as Visioning: Exploring the Impact of Criminal Justice Reform on Health of Populations with Substance Use Disorders

In the context of historic reckoning with the role of the criminal-legal system as a structural driver of health harms, there is mounting evidence that punitive drug policies have failed to prevent problematic drug use while fueling societal harms. In this explainer article, we discuss how simulation modeling provides a methodological framework to explore the potential outcomes (beneficial and harmful) of various drug policy alternatives, from incremental to radical. We discuss potential simulation modeling opportunities while calling for a more active role of simulation modeling in visioning and operationalizing transformative change.

Highlights

This article discusses opportunities for simulation modeling in projecting health and economic impacts (beneficial and harmful) of drug-related criminal justice reforms.We call on modelers to explore radical interventions to reduce drug-related harm and model grand alternative futures in addition to more probable scenarios, with a goal of opening up policy discourse to these options.

Global, regional, and national estimates of tuberculosis incidence and case detection among incarcerated individuals from 2000 to 2019: a systematic analysis

BACKGROUND

People who are incarcerated are at high risk of developing tuberculosis. We aimed to estimate the annual global, regional, and national incidence of tuberculosis among incarcerated populations from 2000 to 2019.

METHODS

We collected and aggregated data for tuberculosis incidence and prevalence estimates among incarcerated individuals in published and unpublished literature, annual tuberculosis notifications among incarcerated individuals at the country level, and the annual number of incarcerated individuals at the country level. We developed a joint hierarchical Bayesian meta-regression framework to simultaneously model tuberculosis incidence, notifications, and prevalence from 2000 to 2019. Using this model, we estimated trends in absolute tuberculosis incidence and notifications, the incidence and notification rates, and the case detection ratio by year, country, region, and globally.

FINDINGS

In 2019, we estimated a total of 125 105 (95% credible interval [CrI] 93 736-165 318) incident tuberculosis cases among incarcerated individuals globally. The estimated incidence rate per 100 000 person-years overall was 1148 (95% CrI 860-1517) but varied greatly by WHO region, from 793 (95% CrI 430-1342) in the Eastern Mediterranean region to 2242 (1515-3216) in the African region. Global incidence per 100 000 person-years between 2000 and 2012 among incarcerated individuals decreased from 1884 (95% CrI 1394-2616) to 1205 (910-1615); however, from 2013 onwards, tuberculosis incidence per 100 000 person-years was stable, from 1183 (95% CrI 876-1596) in 2013 to 1148 (860-1517) in 2019. In 2019, the global case detection ratio was estimated to be 53% (95% CrI 42-64), the lowest over the study period.

INTERPRETATION

Our estimates suggest a high tuberculosis incidence rate among incarcerated individuals globally with large gaps in tuberculosis case detection. Tuberculosis in incarcerated populations must be addressed with interventions specifically tailored to improve diagnoses and prevent transmission as a part of the broader global tuberculosis control effort.

Perceived access to opioid agonist treatment in prison among people with a history of injection drug use: A qualitative study

INTRODUCTION

Opioid agonist treatment (OAT) is associated with a reduced likelihood of hepatitis C incidence, nonfatal overdose, and (re)incarceration among people who inject drugs (PWID), yet factors underpinning decisions to access OAT in prison and postrelease are not well understood. The aim of the qualitative study was to explore the perspectives of OAT access while in prison among PWID recently released from prison in Australia.

METHODS

Eligible participants enrolled in the SuperMix cohort (n = 1303) were invited to take part in a semi-structured interview in Victoria, Australia. Inclusion criteria were informed consent, aged ≥18 years, history of injection drug use, incarcerated for ≥3 months, and released from custody <12 months. The study team analysed data via a candidacy framework to account for macro-structural influences.

RESULTS

Among 48 participants (33 male; ten Aboriginal), most injected drugs in the prior month (n = 41), with heroin most frequently injected (n = 33) and nearly half (n = 23) were currently on OAT (primarily methadone). Most participants described the navigation and permeability of OAT services in prison as convoluted. If not on OAT pre-entry, prison policies often restricted access, leaving participants to withdraw in cells. In turn, some participants commenced OAT postrelease to ensure OAT continuity of care if reincarcerated. Other participants who experienced delayed access to OAT in prison stated no need to initiate while in prison or postrelease as they were now "clean". Last, implementation of OAT delivery in prison (e.g., lack of confidentiality) frequently led to changes in OAT type to avoid peer violence (pressure to divert OAT).

CONCLUSION

Findings draw attention to simplistic notions of OAT accessibility in prisons, illuminating how structural determinants influence choice in PWID decision-making. Suboptimal access and acceptability of OAT delivery in prisons will continue to place PWID at risk of harm postrelease (e.g., overdose).

Hepatitis C care cascade among patients with and without tuberculosis: Nationwide observational cohort study in the country of Georgia, 2015-2020

BACKGROUND

The Eastern European country of Georgia initiated a nationwide hepatitis C virus (HCV) elimination program in 2015 to address a high burden of infection. Screening for HCV infection through antibody testing was integrated into multiple existing programs, including the National Tuberculosis Program (NTP). We sought to compare the hepatitis C care cascade among patients with and without tuberculosis (TB) diagnosis in Georgia between 2015 and 2019 and to identify factors associated with loss to follow-up (LTFU) in hepatitis C care among patients with TB.

METHODS AND FINDINGS

Using national ID numbers, we merged databases of the HCV elimination program, NTP, and national death registry from January 1, 2015 to September 30, 2020. The study population included 11,985 adults (aged ≥18 years) diagnosed with active TB from January 1, 2015 through December 31, 2019, and 1,849,820 adults tested for HCV antibodies between January 1, 2015 and September 30, 2020, who were not diagnosed with TB during that time. We estimated the proportion of patients with and without TB who were LTFU at each step of the HCV care cascade and explored temporal changes. Among 11,985 patients with active TB, 9,065 (76%) patients without prior hepatitis C treatment were tested for HCV antibodies, of which 1,665 (18%) had a positive result; LTFU from hepatitis C care was common, with 316 of 1,557 (20%) patients with a positive antibody test not undergoing viremia testing and 443 of 1,025 (43%) patients with viremia not starting treatment for hepatitis C. Overall, among persons with confirmed viremic HCV infection, due to LTFU at various stages of the care cascade only 28% of patients with TB had a documented cure from HCV infection, compared to 55% among patients without TB. LTFU after positive antibody testing substantially decreased in the last 3 years, from 32% among patients diagnosed with TB in 2017 to 12% among those diagnosed in 2019. After a positive HCV antibody test, patients without TB had viremia testing sooner than patients with TB (hazards ratio [HR] = 1.46, 95% confidence intervals [CI] [1.39, 1.54], p < 0.001). After a positive viremia test, patients without TB started hepatitis C treatment sooner than patients with TB (HR = 2.05, 95% CI [1.87, 2.25], p < 0.001). In the risk factor analysis adjusted for age, sex, and case definition (new versus previously treated), multidrug-resistant (MDR) TB was associated with an increased risk of LTFU after a positive HCV antibody test (adjusted risk ratio [aRR] = 1.41, 95% CI [1.12, 1.76], p = 0.003). The main limitation of this study was that due to the reliance on existing electronic databases, we were unable to account for the impact of all confounding factors in some of the analyses.

CONCLUSIONS

LTFU from hepatitis C care after a positive antibody or viremia test was high and more common among patients with TB than in those without TB. Better integration of TB and hepatitis C care systems can potentially reduce LTFU and improve patient outcomes both in Georgia and other countries that are initiating or scaling up their nationwide hepatitis C control efforts and striving to provide personalized TB treatment.

Mixed-methods evaluation of point-of-care hepatitis C virus RNA testing in a Scottish prison

OBJECTIVES

Hepatitis C virus (HCV) poses a global public health threat. Prisons are a focus of prevention efforts due to high infection burdens. Expedition of treatment for incarcerated people is critical, as many are short-term sentenced. We evaluated point-of-care (PoC) HCV RNA testing in a maximum-security Scottish prison and assessed its impact on transition to treatment. We also evaluated costs and determinants of implementation.

DESIGN

Mixed-methods evaluation of a single-centre care pathway pilot using National Health Service (NHS) data from 2018 to 2021. Descriptive statistics and survival analysis were undertaken. Cost analysis was assessed from a provider perspective. Healthcare staff participated in semistructured interviews and thematic analysis with a deductive approach was undertaken to identify implementation determinants.

SETTING

A large maximum-security Scottish prison health centre administered by the NHS.

PARTICIPANTS

296 incarcerated NHS patients (all men) and six NHS staff members (two men and four women).

INTERVENTIONS

HCV testing using the Cepheid GeneXpert platform with Xpert HCV VL Fingerstick assay.

OUTCOME MEASURES

The main outcome was survival (in days) from HCV test to treatment initiation. Secondary outcomes were cost-per-cure obtained and implementation determinants.

RESULTS

During the pilot, 167 Xpert tests were administered, with an 84% completion rate, and treatment transition was superior for those who received it (p=0.014). Where PoC tests were administered, shorter survival to treatment was observed (19 vs 33 days: adjusted HR (aHR) 1.91 (1.03-3.55), p=0.040; 19 vs 50 days; aHR 3.76 (1.67-8.46), p=0.001). PoC was costlier than conventional testing. In qualitative analysis, most facilitators were observed among characteristics of individual domain while most barriers were noted in the inner setting.

CONCLUSIONS

Integrating PoC HCV RNA diagnosis into nurse-led HCV care in a maximum-security prison health centre shortens survival to HCV treatment. However, there are cost implications to this approach and multiple determinants that impact on implementation should be addressed.

Modelling the impact and cost-effectiveness of non-governmental organizations on HIV and HCV transmission among people who inject drugs in Ukraine

INTRODUCTION

People who inject drugs (PWID) in Ukraine have high prevalences of HIV and hepatitis C virus (HCV). Non-governmental organizations (NGOs) provide PWID with needles/syringes, condoms, HIV/HCV testing and linkage to opioid agonist treatment (OAT) and antiretroviral therapy (ART). We estimated their impact and cost-effectiveness among PWID.

METHODS

A dynamic HIV and HCV transmission model among PWID was calibrated using data from four national PWID surveys (2011-2017). The model assumed 37-49% coverage of NGOs among community PWID, with NGO contact reducing injecting risk and increasing condom use and recruitment onto OAT and ART. We estimated the historic (1997-2021) and future (2022-2030, compared to no NGO activities from 2022) impact of NGOs in terms of the proportion of HIV/HCV infections averted and changes in HIV/HCV incidence. We estimated the future impact of scaling-up NGOs to 80% coverage with/without scale-up in OAT (5-20%) and ART (64-81%). We estimated the cost per disability-adjusted life-year (DALY) averted of current NGO provision over 2022-2041 compared to NGO activities stopping over 2022-2026, but restarting after that till 2041. We assumed average unit costs of US$80-90 per person-year of NGO contact for PWID.

RESULTS

With existing coverage levels of NGOs, the model projects that NGOs have averted 20.0% (95% credibility interval: 13.3-26.1) and 9.6% (5.1-14.1) of new HIV and HCV infections among PWID over 1997-2021, respectively, and will avert 31.8% (19.6-39.9) and 13.7% (7.5-18.1) of HIV and HCV infections over 2022-2030. With NGO scale-up, HIV and HCV incidence will decrease by 54.2% (43.3-63.8) and 30.2% (20.5-36.2) over 2022-2030, or 86.7% (82.9-89.3) and 39.8% (31.4-44.8) if OAT and ART are also scaled-up. Without NGOs, HIV and HCV incidence will increase by 51.6% (23.6-76.3) and 13.4% (4.8-21.9) over 2022-2030. Current NGO provision over 2022-2026 will avert 102,736 (77,611-137,512) DALYs when tracked until 2041 (discounted 3% annually), and cost US$912 (702-1222) per DALY averted; cost-effective at a willingness-to-pay threshold of US$1548/DALY averted (0.5xGDP).

CONCLUSIONS

NGO activities have a crucial preventative impact among PWID in Ukraine which should be scaled-up to help achieve HIV and HCV elimination. Disruptions could have a substantial detrimental impact.

Epidemiology of injecting drug use, prevalence of injecting-related harm, and exposure to behavioural and environmental risks among people who inject drugs: a systematic review

BACKGROUND

People who inject drugs are exposed to various and changing risk environments and are at risk of multiple harms related to injecting drug use (IDU). We aimed to undertake a global systematic review of the prevalence of IDU, key IDU-related harms (including HIV, hepatitis C virus [HCV], and hepatitis B virus [HBV] infection and overdose), and key sociodemographic characteristics and risk exposures for people who inject drugs.

METHODS

We systematically searched for data published between Jan 1, 2017, and March 31, 2022, in databases of peer-reviewed literature (MEDLINE, Embase, and PsycINFO) and grey literature as well as various agency or organisational websites, and disseminated data requests to international experts and agencies. We searched for data on the prevalence, characteristics, and risks of people who inject drugs, including gender, age, sexuality, drug-use patterns, HIV, HCV, and HBV infections, non-fatal overdose, depression, anxiety, and injecting-related disease. Additional data were extracted from studies identified in our previous review. Meta-analyses were used to pool the data where multiple estimates were available for a country. We present country, regional, and global estimates for each variable examined.

FINDINGS

We screened 40 427 reports published between 2017 and 2022, and the 871 eligible reports identified were added to the 1147 documents from the previous review. Evidence of IDU was documented in 190 of 207 countries and territories, and 14·8 million people (95% uncertainty interval [UI] 10·0-21·7) aged 15-64 years globally were estimated to inject drugs. Existing evidence suggests that there might be 2·8 million (95% UI 2·4-3·2) women and 12·1 million (95% UI 11·0-13·3) men who inject drugs globally, and that 0·4% (95% CI 0·3-1·3) of people who inject drugs identify as transgender. The amount of available data on key health and social risks among people who inject drugs varied widely across countries and regions. We estimated that 24·8% (95% CI 19·5-31·6) of people who inject drugs globally had experienced recent homelessness or unstable housing, 58·4% (95% CI 52·0-64·8) had a lifetime history of incarceration, and 14·9% (95% CI 8·1-24·3) had recently engaged in sex work, with substantial geographical variation. Injecting and sexual risk behaviour varied considerably geographically, as did risks of harms. Globally, we estimated that 15·2% (95% CI 10·3-20·9) of people who inject drugs are living with HIV, 38·8% (95% CI 31·4-46·9) have current HCV infection, 18·5% (95% CI 13·9-24·1) have recently overdosed, and 31·7% (95% CI 23·6-40·5) have had a recent skin or soft tissue infection.

INTERPRETATION

IDU is being identified in a growing number of countries and territories that comprise more than 99% of the global population. IDU-related health harms are common, and people who inject drugs continue to be exposed to multiple adverse risk environments. However, quantification of many of these exposure and harms is inadequate and must be improved to allow for better targeting of harm-reduction interventions for these risks.

Transmission of tuberculosis in an incarcerated population during the subclinical period: A cross-sectional study in Qingdao, China

Objectives

As a closed gathering place, prison is the cradle of tuberculosis (TB) outbreak. Therefore, the analysis of the prevalence rate and risk factors of latent tuberculosis infection (LTBI) in prison will be a necessary measure to intervene in the spread of tuberculosis.

Methods

In this study, we consecutively recruited 506 adult prisoners in Qingdao to carry out this cross-sectional study. TB and LTBI were screened by IGRA, X-ray, X-pert, sputum smear and culture.

Results

A total of 17 TB, 101 LTBI and 388 HC were identified, with an infection rate of 23.32% (118/506) and a TB incidence rate of 3282/100,000 population. Age, malnutrition and inmates living with TB prisoners were risk factors for LTBI. Additionally, most TB cases (70.59%, 12/17) were subclinical tuberculosis (STB), contributing significantly to TB transmission.

Conclusion

Our results demonstrate that the transmission efficiency of asymptomatic patients is not essentially different from that of symptomatic patients, indicating that TB transmission occurs during the subclinical period. Our findings highlight the need to strengthen active case-finding strategies to increase TB case detection in this population.

The socio-demographic, clinical characteristics and outcomes of tuberculosis among HIV infected adults in Lithuania: A thirteen-year analysis

BACKGROUND

Tuberculosis (TB) is a public health problem in Lithuania, among the 18 high-priority TB countries in the European region, and the most common AIDS-indicative disease with the highest proportion in the EU/EEA since 2015. The study aimed to identify socio-demographic, clinical characteristics and their relationship with TB outcomes in TB-HIV co-infected patients in Lithuania.

METHODS

A retrospective chart review analysed the characteristics of TB-HIV co-infected adults registered in State Information System of Tuberculosis over 2008-2020. The factors associated with drug-resistant TB and unsuccessful treatment outcome were identified by multivariable logistic regression.

RESULTS

The study included 345 cases in 311 patients (239 new, 106 previously treated cases), median age 40 years (IQR 35-45), 80.7% male. 67.8% patients knew their HIV-positive status before TB diagnosis, median time to TB diagnosis was 8 years (IQR 4-12). 83.6% were unemployed, 50.5%-anytime intravenous drug users (IDU), 34.9% abused alcohol. Drug-resistant TB rates in new and previously treated TB cases were 38.1% and 61.3%, respectively. In multivariable analysis, higher risk of drug-resistant TB was associated with imprisonment in new (aOR 3.35; 95%CI 1.17-9.57) and previously treated (aOR 6.63; 95%CI 1.09-40.35) cases. In 52.3% of new TB cases and in 42.5% previously treated TB cases the treatment outcomes were unsuccessful. In multivariable analysis of new TB cases, current imprisonment (aOR 2.77; 95%CI 1.29-5.91) and drug-resistant TB (aOR 2.18; 95%CI 1.11-4.28) were associated with unsuccessful treatment outcome. In multivariable analysis of previously treated TB cases, female gender (aOR 11.93; 95%CI 1.86-76.69), alcohol abuse (aOR 3.17; 95%CI 1.05-9.58), drug-resistant TB (aOR 4.83; 95%CI 1.53-15.28) were associated with unsuccessful treatment outcome.

CONCLUSIONS

In the TB-HIV-infected adult cohort in Lithuania, unemployment, imprisonment, IDU, alcohol abuse, known to be risk factors for TB, were very frequent. Drug resistance was an undeniable risk factor for unsuccessful treatment outcome and imprisonment was associated with drug resistant TB.

Incarceration history, antiretroviral therapy, and stigma: A cross-sectional study of people with HIV who inject drugs in St. Petersburg, Russia

BACKGROUND

The HIV epidemic is intertwined with substance use and incarceration in Russia. The relationships between incarceration history, HIV treatment history, and stigma experiences among people with HIV (PWH) who inject drugs in Russia have not been well described.

METHODS

We conducted a cross-sectional study of a cohort of PWH with opioid use disorder who inject drugs (n=201) recruited at a narcology (substance use treatment) hospital in St. Petersburg, Russia from September 2018 to December 2020. The primary analysis evaluated the association between self-reported prior incarceration and prior antiretroviral therapy (ART) initiation using multivariable logistic regression to adjust for demographic, social, and clinical covariates. We used multivariable linear regression models to analyze associations between prior incarceration and two secondary outcomes: HIV stigma score (11-item abbreviated Berger scale) and substance use stigma score (21-item combination of Substance Abuse Self-Stigma Scale and Stigma-related Rejection Scale).

RESULTS

Mean age was 37 (SD 5) years; 58.7% were male. Participants had been living with HIV for a mean of 13 (SD 6) years. Over two thirds (69.2%) of participants reported prior incarceration. One third (35.3%) of participants reported prior ART initiation. Prior incarceration was not significantly associated with prior ART initiation (AOR 1.76; 95% CI: 0.81, 3.83). Prior incarceration was associated with a lower HIV stigma score (adjusted mean difference in z-score: -0.50; 95%CI: -0.81, -0.19) but was not significantly associated with substance use stigma score (adjusted mean difference in z-score: -0.10; 95%CI: -0.42, 0.21).

CONCLUSION

Prior incarceration was common, and rates of prior ART initiation were low even though most participants had been living with HIV for at least a decade. We did not find an association between prior incarceration and prior ART initiation, which suggests a need to explore whether opportunities to initiate ART during or after incarceration are missed.

Substance use policy and practice in the COVID-19 pandemic: Learning from early pandemic responses through internationally comparative field data

The COVID-19 pandemic has created an unprecedented natural experiment in drug policy, treatment delivery, and harm reduction strategies by exposing wide variation in public health infrastructures and social safety nets around the world. Using qualitative data including ethnographic methods, questionnaires, and semi-structured interviews with people who use drugs (PWUD) and Delphi-method with experts from field sites spanning 13 different countries, this paper compares national responses to substance use during the first wave of the COVID-19 pandemic. Field data was collected by the Substance Use x COVID-19 (SU x COVID) Data Collaborative, an international network of social scientists, public health scientists, and community health practitioners convened to identify and contextualise health service delivery models and social protections that influence the health and wellbeing of PWUD during COVID-19. Findings suggest that countries with stronger social welfare systems pre-COVID introduced durable interventions targeting structural drivers of health. Countries with fragmented social service infrastructures implemented temporary initiatives for PWUD led by non-governmental organisations. The paper summarises the most successful early pandemic responses seen across countries and ends by calling for greater systemic investments in social protections for PWUD, diversion away from criminal-legal systems toward health interventions, and integrated harm reduction, treatment and recovery supports for PWUD.

Modelling the contribution of incarceration and public health oriented drug law reform to HCV transmission and elimination among PWID in Tijuana, Mexico

BACKGROUND

Incarceration is associated with increased risk of hepatitis C virus (HCV) among people who inject drugs (PWID). Mexico's previous attempt in implementing a public health-oriented drug law reform resulted in minimal impact on incarceration among PWID. However, implementation of reforms alongside Mexico's HCV elimination program has the potential to reshape the HCV epidemic among PWID in the next decade. We use data from a cohort of PWID in Tijuana, Mexico, to inform epidemic modeling to assess the contribution of incarceration and fully implemented drug reform on HCV transmission and elimination among PWID.

METHODS

We developed a dynamic, deterministic model of incarceration, HCV transmission and disease progression among PWID. The model was calibrated to data from Tijuana, Mexico, with 90% HCV seroprevalence among 10,000 PWID. We estimated the 10-year population attributable fraction (PAF) of incarceration to HCV incidence among PWID and simulated, from 2022, the potential impact of the following scenarios: 1) decriminalization (80% reduction in incarceration rates); 2) fully implemented drug law reform (decriminalization and diversion to opiate agonist therapy [OAT]); 3) fully implemented drug law reform with HCV treatment (direct-acting antivirals [DAA]). We also assessed the number DAA needed to reach the 80% incidence reduction target by 2030 under these scenarios.

RESULTS

Projections suggest a PAF of incarceration to HCV incidence of 5.4% (95% uncertainty interval [UI]:0.6-11.9%) among PWID in Tijuana between 2022-2032. Fully implemented drug reforms could reduce HCV incidence rate by 10.6% (95%UI:3.1-19.2%) across 10 years and reduce the number of DAA required to achieve Mexico's HCV incidence reduction goal by 14.3% (95%UI:5.3-17.1%).

CONCLUSIONS

Among PWID in Tijuana, Mexico, incarceration remains an important contributor to HCV transmission. Full implementation of public health-oriented drug law reform could play an important role in reducing HCV incidence and improve the feasibility of reaching the HCV incidence elimination target by 2030.

The development and initial validation of the Russian version of the BASIS-24

BACKGROUND

Efficient and linguistically appropriate instruments are needed to assess response to addiction treatment, including severity of addiction/mental health status. This is critical for Russian-speaking persons in Eastern Europe and Central Asia (EECA) where Medications for Opioid Use Disorder (MOUD) remain underscaled to address expanding and intertwined opioid, HIV, HCV and tuberculosis epidemics. We developed and conducted a pilot validation of a Russian version of the 24-item Behavior and Symptom Identification Scale (BASIS-24), an addiction/mental health severity instrument with six subscales, previously validated in English.

METHODS

Using the Mapi approach, we reviewed, translated, and back-translated the content to Russian, pilot-tested the Russian-version (BASIS-24-R) among new MOUD patients in Ukraine (N = 283). For a subset of patients (n = 44), test-rest was performed 48 h after admission to reassess reliability of BASIS-24-R. Exploratory principal component analysis (PCA) assessed underlying structure of BASIS-24-R.

RESULTS

Cronbach alpha coefficients for overall BASIS-24-R and 5 subscales exceeded 0.65; coefficient for Relationship subscale was 0.42. The Pearson correlation coefficients for overall score and all subscales on the BASIS-24-R exceeded 0.8. Each item loaded onto factors that corresponded with English BASIS-24 subscales ≥ 0.4 in PCA.

CONCLUSION

Initial version of BASIS-24-R appears statistically valid in Russian. Use of the BASIS-24-R has potential to guide MOUD treatment delivery in the EECA region and help to align addiction treatment with HIV prevention goals in a region where HIV is concentrated in people who inject opioids and where healthcare professionals have not traditionally perceived MOUD as effective treatment, particularly for those with mental health co-morbidities.

Exploratory qualitative study examining acceptability of strategies to improve access to substance use treatment and HIV prevention services for young adults on probation in Ukraine

OBJECTIVE

Adults <30 years' of age experience elevated HIV-rates in Ukraine. Young adults (YA) involved in the criminal justice system (CJS) are at an increased HIV-risk given elevated rates of substance use, engagement in high-risk sexual behaviour and insufficient healthcare access. The objective of this exploratory study was to investigate the acceptability of strategies to refer and link CJS-involved YA to HIV-prevention and substance use treatment services from CJS settings.

DESIGN

We conducted qualitative individual interviews with CJS-involved YA (18-24 years), and CJS stakeholders. Interviews were guided by the Social Ecological Model. Interviews with YA explored substance use and sexual behaviour, and acceptability of strategies to link YA to HIV-prevention and substance use treatment services from CJS. Stakeholder interviews explored system practices addressing HIV-prevention and substance use and addiction. Data were analysed using Inductive Thematic Analysis.

SETTING

Data were collected in three locales, prior to the 2022 Russian-Ukrainian conflict.

PARTICIPANTS

Thirty YA and 20 stakeholders.

RESULTS

Most YA were men, reported recent injection drug use and were M age=23 years. YA were receptive to linkage to HIV-prevention services from CJS; this was shaped by self-perceived HIV-risk and lack of access to HIV-prevention services. YA were less receptive to being referred to substance use treatment services, citing a lack of self-perceived need and mistrust in treatment efficacy. Stakeholders identified multilevel contextual factors shaping acceptability of HIV-prevention and substance use treatment from CJS (eg, stigma).

CONCLUSIONS

Findings should be reviewed as a historical record of the pre-conflict context. In that context, we identified strategies that may have been used to help curtail the transmission of HIV in a population most-at-risk, including CJS-involved YA. This study demonstrates that improving access to substance use treatment and HIV-prevention services via CJS linkage were acceptable if provided in the right conditions (eg, low or no-cost, confidential).

Results of a Model of Delivering Hepatitis C Care in a Homeless Metropolitan Population in England

INTRODUCTION

Given the hepatitis C virus (HCV) burden and despite curative treatments, more efforts focused on scaling-up testing and treatment in homeless populations are needed. This project aimed to implement education and flexible on-site HCV testing, treatment, and follow-up for a homeless population in south London and to evaluate engagement, therapy initiation, and cure rates.

METHODS

A mobile unit (van) for on-site HCV education, screening, treatment, and follow-up was placed on the street in a well-known homeless population areas from January 2018 to September 2021. Homeless was defined as living in temporary housing (hostel/hotel-based) or living on the street (street-based). Sociodemographic status, risk factors, comorbidities, concomitant medication, and data related with HCV treatment were recorded. Univariable and multivariable modeling were performed for treatment initiation and sustained virological response (SVR).

RESULTS

Nine hundred forty homeless people were identified and 99.3% participated. 56.2% were street-based, 243 (26%) tested positive for HCV antibody, and 162 (17.4%) were viremic. Those with detectable HCV RNA had significantly more frequent psychiatric disorders, active substance use disorders, were on opioid agonist treatment, had advanced fibrosis, and had lower rates of previous treatment in comparison with undetectable HCV RNA. Overall treatment initiation was 70.4% and SVR was 72.8%. In the multivariable analysis, being screened in temporary housing (odds ratio [OR] 3.166; P = 0.002) and having opioid agonist treatment (OR 3.137; P = 0.004) were positively associated with treatment initiation. HCV treatment adherence (OR 26.552; P < 0.001) was the only factor associated with achieving SVR.

DISCUSSION

Promoting education and having flexible and reflex mobile on-site testing and treatment for HCV in the homeless population improve engagement with the health care system, meaning higher rates of treatment initiation and SVR. However, street-based homeless population not linked with harm reduction services are less likely to initiate HCV treatment, highlighting an urgent need for a broad health inclusion system.

Preliminary analysis of self-reported quality health indicators of patients on opioid agonist therapy at specialty and primary care clinics in Ukraine: A randomized control trial

International agencies recommend integrating addiction treatment into primary care for people who inject drugs (PWID) with opioid use disorder (OUD). Empirical data supporting integration that incorporates comprehensive health outcomes, however, are not known. For this randomized controlled trial in Ukraine, adult PWID with OUD were randomized to receive opioid agonist therapy (OAT) in specialty addiction treatment clinics (SATC) or to primary care clinics (PCCs). For those randomized to PCC, they were subsequently allocated to PCCs where clinicians received pay-for-performance (P4P) incentives (PCC with P4P) or not (PCC without P4P). Participating cities had one of each of the three intervention sites to control for geographic variation. Ongoing tele-education specialty training (OAT, HIV, tuberculosis) was provided to all PCCs. While the primary outcome for the parent trial focuses on patient medical record data, this preliminary analysis focuses on assessment of self-reported achievement of nationally recommended quality health indicators (QHIs) which is summed as a composite QHI score. Secondary outcomes included specialty and primary care QHI subscores. This study occurred from 01/20/2018-11/1/2020 with 818 of 990 randomized participants having complete self-reported data for analysis. Relative to SATC (treatment as usual), the mean composite QHI score was 12.7 (95% CI: 10.1-15.3; p<0.001) percentage points higher at PCCs; similar and significantly higher scores were observed in PCCs compared to SATCs for both primary care (PCC vs SATC: 18.4 [95% CI: 14.8-22.0; p<0.001] and specialty (PCC vs SATC: 5.9 [95% CI: 2.6-9.2; p<0.001] QHI scores. Additionally, the mean composite QHI score was 4.6 (95% CI: 2.0-7.2; p<0.001) points higher in participants with long term (>3 months) experience with OAT compared to participants newly initiating OAT. In summary, PWID with OUD receive greater primary care and specialty healthcare services when receiving OAT at PCCs supported by tele-education relative to treatment as usual provided in SATCs. Clinical trial registration: This trial was registered at clinicaltrials.gov and can be found using the following registration number: NCT04927091.

'In Short, We Will Deport You': Disrupted temporalities of migrants with HIV in Russia

Migrants experience several challenges en route to or in their host country. Current legislation in Russia imposes a permanent ban on international migrants with HIV obtaining a residence permit in Russia. Using qualitative methodology, we conducted semi-structured interviews with 15 international migrants who have lived with HIV in Russia and 12 interviews with healthcare providers in Russia. With the help of Bonnington's temporal framework, the study finds that the HIV-positive status of migrants becomes a biographical event that interrupts their migration cycle, thereby leading to the disruption of their normal life course which results in 'short term planning' and instability. Although most people living with HIV face similar challenges, Russian law concerning international migrants living with HIV worsens their living experience in Russia. International migrants living with HIV further face social exclusion, serious stigma and discrimination. The results show that the country's demand for migrants with HIV to leave the country to reduce the spread of HIV in Russia is counterproductive: it does not mobilise heath-seeking behaviour among migrants. Therefore, such legislation has to be amended to encourage international migrants living with HIV to access adequate HIV services.

Interest without uptake: A mixed-methods analysis of methadone utilization in Kyrgyz prisons

HIV incidence continues to increase in Eastern Europe and Central Asia (EECA), in large part due to non-sterile injection drug use, especially within prisons. Therefore, medication-assisted therapy with opioid agonists is an evidence-based HIV-prevention strategy. The Kyrgyz Republic offers methadone within its prison system, but uptake remains low. Screening, Brief Intervention, and Referral to Treatment (SBIRT) is a framework for identifying people who would potentially benefit from methadone, intervening to identify OUD as a problem and methadone as a potential solution, and providing referral to methadone treatment. Using an SBIRT framework, we screened for OUD in Kyrgyz prisons among people who were within six months of returning to the community (n = 1118). We enrolled 125 people with OUD in this study, 102 of whom were not already engaged in methadone treatment. We conducted a pre-release survey followed by a brief intervention (BI) to address barriers to methadone engagement. Follow-up surveys immediately after the intervention and at 1 month, 3 months, and 6 months after prison release assessed methadone attitudes and uptake. In-depth qualitative interviews with 12 participants explored factors influencing methadone utilization during and after incarceration. Nearly all participants indicated favorable attitudes toward methadone both before and after intervention in surveys; however, interest in initiating methadone treatment remained very low both before and after the BI. Qualitative findings identified five factors that negatively influence methadone uptake, despite expressed positive attitudes toward methadone: (1) interpersonal relationships, (2) interactions with the criminal justice system, (3) logistical concerns, (4) criminal subculture, and (5) health-related concerns.

The role of depression in secondary HIV transmission among people who inject drugs in Vietnam: A mathematical modeling analysis

BACKGROUND

Among people who inject drugs (PWID), depression burden is high and may interfere with HIV prevention efforts. Although depression is known to affect injecting behaviors and HIV treatment, its overall impact on HIV transmission has not been quantified. Using mathematical modeling, we sought to estimate secondary HIV transmissions and identify differences by depression among PWID.

METHODS

We analyzed longitudinal data from 455 PWID living with HIV in Vietnam during 2009-2013. Using a Bernoulli process model with individual-level viral load and behavioral data from baseline and 6-month follow-up visits, we estimated secondary HIV transmission events from participants to their potentially susceptible injecting partners. To evaluate differences by depression, we compared modeled transmissions per 1,000 PWID across depressive symptom categories (severe, mild, or no symptoms) in the three months before each visit.

RESULTS

We estimated a median of 41.2 (2.5th, 97.5th percentiles: 33.2-49.2) secondary transmissions from all reported acts of sharing injection equipment with 833 injecting partners in the three months before baseline. Nearly half (41%) of modeled transmissions arose from fewer than 5% of participants in that period. Modeled transmissions per 1,000 PWID in that period were highest for severe depressive symptoms (100.4, 80.6-120.2) vs. mild (87.0, 68.2-109.4) or no symptoms (78.9, 63.4-94.1). Transmission estimates fell to near-zero at the 6-month visit.

CONCLUSIONS

Secondary transmissions were predicted to increase with depression severity, although most arose from a small number of participants. Our findings suggest that effective depression interventions could have the important added benefit of reducing HIV transmission among PWID.

Polydrug Use, Sexual Risk, and HIV Testing Among Cisgender Gay, Bisexual, and Other Men and Transgender and Nonbinary Individuals Who Have Sex With Men in Kazakhstan

This study examined substance use and sexual risk correlates of HIV testing among cisgender gay, bisexual, and other men (MSM) and transgender and nonbinary individuals (TSM) who have sex with men in Kazakhstan. We analyzed baseline data from an HIV prevention trial collected prior to intervention deployment (N = 304). Multivariable logistic regression analyses revealed that lifetime HIV testing was positively associated with poly-drug use (AOR = 4.4, 95% CI [2.0, 9.9]) and negatively with sexual risk (AOR = 0.4, 95% CI [0.2, 1.0]). Similarly, recent HIV testing was positively associated with polydrug use (AOR = 2.7, 95% CI [1.4, 5.2]) and negatively with sexual risk (AOR = 0.5, 95% CI [0.3, 0.9]). Current HIV testing was negatively associated with sexual risk (AOR = 0.6, 95% CI [0.3. 0.9]). Findings support the value of integrating drug treatment with HIV testing among MSM and TSM in Kazakhstan.

HIV testing inside Brazilian female prisons: results of a national survey

This study aimed to identify the prevalence of women in prisons who have already had an HIV test inside prison and the factors associated with this test. A cross-sectional study was carried out with 1327 women in 15 prisons in 9 states in Brazil. Almost 60% (95% CI: 57.8-63.7) of women have already been tested for HIV in prison. The factors associated with this HIV test were age ≥41 years (OR = 1.9; 95% CI = 1.2-2.9), highest level of education (OR = 1.9; 95% CI = 1.3-2.8), having been arrested 3 or more times (OR = 1.9; 95% CI = 1.3-2.8), having received information about HIV/STI in the lifetime (OR = 1.4; 95% CI = 1.1-1.9) and perceived themselves to be at no risk for HIV infection (OR = 1.7; 95% CI = 1.2-2.5), black or mixed race (OR = 0.7; 95% CI = 0.5-0.9) and having a male sexual partner (OR = 0.6; 95% CI = 0.5-0.9). The routine HIV testing in prisons needs to be expanded to promote HIV prevention for a population with limited access to these services outside of prison.

Implementation opportunities for scaling up methadone maintenance treatment in Kyrgyzstan: Methadone dosage and retention on treatment over two years

Background

Methadone maintenance treatment (MMT) is the most effective and cost-effective strategy to control HIV in Central Asian countries, where the epidemic is concentrated among people who inject drugs (PWID) who use opioids.

Methods

Using data from a prospective observational database of all people initiated on MMT in Kyrgyzstan since 2008, we analyzed a more contemporary subset of data for all persons receiving MMT from January 2017 through June 2021 after the national treatment guidelines were changed. Retention on MMT was assessed at 1, 6, 12, and 24 months and predictive variables included were dosage levels, HIV status, and type of clinical setting using survival analysis. Predictors of treatment dropout were estimated using Cox multivariate regression models.

Results

Among the 940 MMT patients, the proportion receiving low (<40mg), medium (40-85mg), and high (>85mg) dosage levels was 37.9%, 42.2%, and 19.9%, respectively. Increasing MMT dosage level was significantly (p<0.0001) correlated with retention at 1 (90%, 98%, 100%), 6 (42%, 63%, 95%), 12 (33%, 55%, 89%), and 24 (16%, 45%, 80%) months, respectively, with no differences between community and correctional settings. Significant predictors of dropout at 12 months included low (aHR=8.0; 95%CL=5.8-11.0) and medium (aHR=3.5; 95%CL=2.5-4.9) methadone dosage level relative to high dose, receiving MMT in three administrative regions relative to the capital Bishkek, and lower in the tuberculosis-specialized clinic in Bishkek. Clients with HIV receive higher average MMT doses (79.5mg vs 63.1mg; p<0.0001), but MMT retention did not differ after controlling for dosage in this group.

Conclusions

The proportion of patients receiving optimal dosage was low (19.9%). An implementation strategy that focused on getting a larger proportion of MMT on the optimal dosage to promote retention could potentially improve the quality of existing treatment and promote further scale-up of MMT in Kyrgyzstan.

Design and analysis of partially randomized preference trials with propensity score stratification

While the two-stage randomized design allows us to unbiasedly evaluate the impact of patients' treatment preference on the outcome of interest, it may not always be practical to implement in clinical practice; patients with a strong preference may not be willing to be randomized. The more pragmatic, partially randomized preference design (PRPD) allows patients who are unwilling to be randomized, but willing to state their preference, to receive their preferred treatment in lieu of the first-stage randomization in the two-stage design, at the cost of potentially introducing bias in estimating the effects of interest. In this article, we consider the application of propensity score stratification (PSS) in a PRPD to recreate a conditional first-stage randomization based on observed covariates, enabling the estimation and inference of the overall treatment, selection and preference effects with minimum bias. We additionally derive a set of closed-form sample size formulas for detecting all three effects of interest in a PSS-PRPD. Simulation studies demonstrate the bias reduction properties of the PSS-PRPD, and validate the accuracy of the proposed sample size formulas. Our results show that 5 to 10 propensity score strata may be needed to correct for biases in effect estimates, and the exact number of strata needed to achieve the best match between the empirical power and formula prediction may depend on the degree of effect heterogeneity. Finally, we demonstrate our proposed formulas by estimating the required sample sizes to detect treatment, selection and preference effects in the context of the Harapan Study.

A pilot implementation study to scale-up methadone in incarcerated persons with opioid use disorder and retain them on treatment after release in Moldova

BACKGROUND

Eastern Europe and Central Asia have intertwined HIV and incarceration epidemics, concentrated in people who inject drugs. Moldova is one of the few countries in this region that offers methadone within prisons, but uptake and post-release retention remains suboptimal. Screening, brief intervention, and referral to treatment (SBIRT) procedures are a potential implementation strategy to address this problem.

METHODS

From June 1, 2017 to March 3, 2018, we conducted a 2-stage SBIRT strategy in nine prisons and four pre-trial detention facilities in Moldova among incarcerated persons with opioid use disorder (OUD; N = 121) and within 90 days of release. Survey results were analyzed to evaluate the effect of the SBIRT strategy on the uptake of and post-release retention on methadone maintenance treatment (MMT).

RESULTS

Among the 121 screened with OUD, 27 were on MMT at baseline within the prison and this number increased to 41 after the two-step SBIRT intervention, reflecting a 51.9% increase over baseline. Eleven (78.6%) of the 14 participants that newly started MMT did so only after completing both SBIRT sessions. The brief intervention did not significantly improve knowledge about methadone but did improve attitudes towards it. Among the 41 participants who received methadone during this trial, 40 (97.6%) were retained 6 months after release; the one participant not retained was on methadone at the time of the intervention and had planned to taper off.

CONCLUSION

The SBIRT strategy significantly improved participant attitudes, but treatment initiation mostly occurred after completing both sessions, including soon after release, but remained low overall. Work within the Moldovan prison subculture to dispel negative myths and misinformation is needed to further scale-up OAT in Moldova.

Spatial and Temporal Trends in HIV/AIDS Burden Among Worldwide Regions From 1990 to 2019: A Secondary Analysis of the Global Burden of Disease Study 2019

Purpose

HIV/AIDS is a critical public health concern worldwide. This article investigated the spatial and temporal trends in HIV/AIDS burden from 1990 to 2019.

Methods

Data were extracted from the Global Burden of Disease (GBD) Study 2019. The estimated annual percentage change (EAPC) and the age-standardized rate (ASR) were used to quantify the change in trends at the global, regional, and national levels.

Results

In terms of temporal trends, during the period 1990–2004, increasing trends in prevalence (EAPC = 7.47, 95% confidence interval [CI] 5.84, 9.12), death (EAPC = 10.85, 95% CI 8.90–12.84), and disability-adjusted life years (DALYs) (EAPC = 10.40, 95% CI 8.47–12.36) of HIV/AIDS were observed. During the period 2005–2019, the global trends in HIV/AIDS incidence, death, and DALYs of HIV/AIDS decreased, with the EAPCs of −2.68 (95% CI−2.82–−2.53), −6.73 (95% CI −6.98–−6.47), and −6.75 (95% CI −6.95–−6.54), respectively. However, the disease prevalence showed a slight increasing trend (EAPC = 0.71, 95% CI 0.54–0.87). In terms of spatial trends, over the past 15 years, trends in HIV/AIDS incidence of HIV/AIDS appeared upward in High-middle and High sociodemographic index (SDI) areas (EAPC = 6.51, 95% CI 5.50–7.53; EAPC = 2.31, 95% CI 2.02–2.60, respectively).

Conclusion

Decreasing trends in HIV/AIDS incidence, death, and DALYs have been observed worldwide over the past 15 years, especially in death and DALYs rates. However, the global population living with HIV/AIDS is still increasing. It is worth noting that an unfavorable trend emerged in High-middle and High SDI areas. Prevention and control of HIV/AIDS still need to be strengthened to counteract these concerning trends.

A gender lens is needed in hepatitis C elimination research

The World Health Organisation has established a goal of eliminating the hepatitis C virus (HCV) as a public health threat by 2030. Considerable effort is being directed towards research to support and enhance HCV treatment uptake among people who inject drugs, but there is a distinct lack of attention given to gender in this work. We argue that a gender lens is needed to make visible the limitations of current HCV elimination research, and support the development of innovative, inclusive approaches to HCV treatment. Partnerships between researchers and people who inject drugs are essential in this work, particularly in the development and evaluation of programs by and for women who inject drugs. Failure to acknowledge the gendered dimensions of HCV elimination risks entrenching gender disparities in access to treatment and cure.

Multi-level implementation factors that influence scale-up of methadone maintenance treatment in Moldovan prisons: A qualitative study

INTRODUCTION

People who inject drugs (PWID) are overrepresented in prison populations, especially in the Eastern European and Central Asian region (EECA), where HIV incidence and mortality continue to rise. Modeling data suggest that methadone maintenance treatment (MMT) scale-up in prison with continuation after release could substantially reduce new HIV infections. Moldova, one of four countries in the EECA to have introduced MMT in prisons, has faced challenges with its scale-up.

METHOD

To improve implementation of MMT in Moldovan prisoners, we analyzed the qualitative interviews of 44 recently released Moldovan prisoners with opioid use disorder who either accepted or rejected MMT while incarcerated; these 44 were among a subset of 56 participants in a quantitative survey who had complete interview data. After translating and back-translating interviews, we used content analysis to identify key barriers and facilitators to MMT uptake.

RESULTS

Our qualitative analyses revealed that positive attitudes toward methadone facilitated treatment uptake, yet the study identified three thematic barriers as to why PWID do not accept MMT while in prison, including: 1) negative personal attitudes toward MMT; 2) stigmatization of MMT by informal hierarchies within prison; and 3) distrust of the formal prison hierarchy (i.e., administration), which provides MMT.

CONCLUSION

Overall, the social forces of the two prisoner hierarchies and distrust between them appeared to outweigh the perceived benefits of MMT and impacted MMT uptake. Here we provide strategies to promote MMT more effectively in prison settings.

Injection and Non-Injection Drug Use Among Adults with Diagnosed HIV in the United States, 2015-2018

Understanding behavioral characteristics and health outcomes of people with HIV (PWH) who inject drugs and PWH who use drugs, but do not inject, can help inform public health interventions and improve HIV clinical outcomes. However, recent, nationally representative estimates are lacking. We used 2015-2018 Medical Monitoring Project data to examine health outcome differences among adults with diagnosed HIV who injected drugs or who only used non-injection drugs in the past year. Data were obtained from participant interviews and medical record abstraction. We reported weighted percentages and prevalence ratios with predicted marginal means to assess differences between groups (P < 0.05). PWH who injected drugs were more likely to engage in high-risk sex; experience depression and anxiety symptoms, homelessness, and incarceration; and have lower levels of care retention, antiretroviral therapy adherence, and viral suppression. Tailored, comprehensive interventions are critical for improving outcomes among PWH who use drugs, particularly among those who inject drugs.

Time to start of tuberculosis treatment in penitentiary system of Kyrgyz Republic: A retrospective cohort study

Background

Tuberculosis burden among the incarcerated population is generally higher than that of general population. Early diagnosis and prompt initiation of treatment are key strategies to contain disease transmission. The aim of this study was to determine the time to treatment initiation among inmates with new smear or Xpert MTB/RIF positive pulmonary tuberculosis and explore risk factors associated with delayed treatment initiation in prison settings.

Methods

We conducted a retrospective cohort study using routine health care data from prison settings in Kzrgyz Republic on new pulmonary tuberculosis patients confirmed by smear microscopy or GeneXpert MTB/RIF during 2014–2019. We computed delay in start of treatment—days from specimen collection to treatment initiation—for exposure variables. We dichotomized treatment delay using 10-day cut-off point,and used logistic regression to identify factors associated with treatment delay.

Results

Among 406 cases included into analysis, the median delay to treatment initiation was 7 days [IQR: 2–16 days]. Using 10-day cut-off, 189 (46.6%) patients had delayed treatment initiation. Treatment delay was negatively associated with smear positivity [adjusted OR (aOR) = 0.44, 95% CI 0.29–0.68] compared to smear negative patients, while patients with isoniazid resistant (aOR = 2.61, 95%CI 1.49–4.56) and rifampicin resistant tuberculosis (aOR = 4.14, 95%CI 2.56–6.77) had increased delay compared to patients who were sensitive for both rifampicin and isoniazid.

Conclusion

Timely diagnosis and effective treatment remain the cornerstone of TB control program populations in the general and in prison settings in particular. Prison authorities need to address all potential areas of delay in TB diagnosis and treatment to strengthen their TB control efforts so that prisons remain free of TB for detainees, prison staff and visitors. These include improved supply of TB drugs, early detection of TB cases and improved collaboration with the health authorities outside the prison system.

Methadone within prison and linkage to and retention in treatment upon community release for people with opioid use disorder in Kyrgyzstan: Evaluation of a national program

BACKGROUND

HIV incidence in Eastern Europe and Central Asia (EECA) continues to increase, primarily among people who inject drugs (PWID) and people in prisons. In Kyrgyzstan, an estimated 35% of people in prison are PWID, and 10% have been diagnosed with HIV. In 2008, Kyrgyzstan became the first country in EECA to provide free and voluntary methadone in prisons. We examine the impact of this national program on methadone within prison as well as linkage to and retention in treatment upon release to the community.

METHODS

Administrative data from a national methadone registry with de-identified information were assessed retrospectively. We examined the delivery of methadone services, including the duration of treatment both within prison and after release, for all prisoners who were prescribed methadone in Kyrgyz prisons from 2008 to 2018. Reasons for discontinuing methadone, HIV status and methadone dose are also analyzed.

RESULTS

Between 2008 and 2018, nine of Kyrgyzstan's 16 prisons offered methadone, and 982 incarcerated people initiated methadone within prison. Prisoners prescribed methadone were mostly male (96.2%), in their mid-30s (mean=34.9 years), and had been incarcerated for a relatively long time (mean = 44.1 months); their mean treatment duration in prison was 12.5 months, and 31.6% had HIV. A subsample (N = 645; 65.7%) of these were released to the community. Of these 645 people, 356 (55.2%) were not taking methadone at the time of release, 128 (19.8%) were on methadone and continued it after release, and the remainder (N=161, 25.0%) were on methadone at the time of release, but subsequently discontinued it, most within the first 7 days after release. Among those continuing methadone, 14.8% (N=19) remained on treatment ≥ 12 months. Independent correlates of linkage to methadone after release included positive HIV status (adjusted hazard ratio (aHR)=1.55; p = 0.033), receipt of methadone before their incarceration (aHR=2.01; p = 0.039), and receipt of methadone at the time of release (aHR = 20.81; p<0.001).

CONCLUSION

This is the first evaluation of within-prison methadone treatment in EECA. Uptake of methadone within prison and retention in treatment after release were both low. Continuous maintenance of treatment throughout incarceration is an opportunity to optimize HIV prevention and link patients to methadone post-release.
