Law enforcement practices associated with HIV infection among injection drug users in Odessa, Ukraine

Police abuse and care engagement of people with HIV who inject drugs in Ukraine

Police abuse affects people who inject drugs (PWID), including those with HIV, and negatively impacts care engagement. This cross-sectional study evaluated police abuse among PWID receiving MOUD (medication for opioid use disorder) living with HIV and associations with HIV treatment adherence and receipt of NGO services. We assessed lifetime and past six-month rates of police abuse among a cohort of Ukrainian PWID with HIV receiving MOUD (n = 190) from August to September 2017. Logistic regression models evaluated associations between past six-month police abuse and past 30-day antiretroviral therapy (ART) adherence, and past six-month NGO service receipt. Almost all (90%) participants reported lifetime police abuse: 77% reported physical violence and 75% reported paying the police to avoid arrest. One in four females (25%) reported police-perpetrated sexual violence. Recent police abuse was reported by 16% of males and 2% of females and was not associated with ART adherence (aOR: 1.1; 95% CI:0.3-5.0) or NGO service receipt (aOR: 3.4; 95% CI:0.6-18.3). While lifetime police abuse rates were high, few participants reported recent police abuse, which was not linked to care engagement. These trends should encourage the Ukrainian government for public health-public safety partnerships and legal interventions to eliminate human rights violations against PWID living with HIV.

The Relationship Between Intersectional Drug Use and HIV Stigma and HIV Care Engagement Among Women Living with HIV in Ukraine

This study used an intersectional approach to explore the association between enacted and internalized drug use and HIV stigma on HIV care outcomes among HIV-positive women who inject drugs in Ukraine. Surveys were conducted in Kyiv in 2019-2020. Among the 306 respondents, 55% were engaged in HIV care. More than half (52%) of participants not engaged in care reported internalized stigma related to both drug use and HIV status (i.e., intersectional stigma), compared to only 35% of those who were engaged in HIV care. Among those engaged in care, 36% reported intersectional enacted stigma compared to 44% of those not engaged in care; however, this difference was not statistically significant in the univariable analysis (p = 0.06). In the univariable analysis, participants who reported intersectional internalized stigma had 62% lower odds of being engaged in HIV care (OR 0.38, 95% CI 0.22, 0.65, p < 0.001). In the adjusted model, reported intersectional internalized stigma (aOR 0.52, 95% CI 0.30, 0.92, p = 0.026), reported intersectional enacted stigma (aOR 0.47, 95% CI 0.23, 0.95, p = 0.036), and knowing their HIV status for more than 5-years (aOR 2.29, 95% CI 1.35, 3.87, p = 0.002) were significant predictors of HIV care engagement. These findings indicate that interventions to improve HIV care engagement must address women's experiences of both HIV and drug use stigma and the different mechanisms through which stigma operates.

Violence, HIV Risks, and Polysubstance Use Among HIV-Positive People Who Inject Drugs in Ukraine

Violence experience has been consistently associated with HIV risks and substance use behaviors. Although many studies have focused on intimate partner violence (IPV), the role of violence at a structural level (i.e., police abuse) remains relevant for people who inject drugs. This study evaluated the association of IPV and police-perpetrated violence experiences with HIV risk behaviors and substance use in a cohort of HIV-positive people who inject drugs in Ukraine. We also evaluated possible moderation effects of gender and socioeconomic status in the links between violence exposure and HIV risk and polysubstance use behaviors. Data came from the Providence/Boston-CFAR-Ukraine Study involving 191 HIV-positive people who inject drugs conducted at seven addiction treatment facilities in Ukraine. Results from logistic regressions suggest that people who inject drugs and experienced IPV had higher odds of polysubstance use than those who did not experience IPV. Verbal violence and sexual violence perpetrated by police were associated with increased odds of inconsistent condom use. The odds of engaging in polysubstance use were lower for women in relation to police physical abuse. We found no evidence supporting socioeconomic status moderations. Violence experiences were associated with substance use and sexual HIV risk behaviors in this cohort of HIV-positive people who inject drugs in Ukraine. Trauma-informed prevention approaches that consider both individual and structural violence could improve this population's HIV risks.

Reducing police occupational needle stick injury risk following an interactive training: the SHIELD cohort study in Mexico

Objective

At a time of unprecedented attention to the public health impact of policing, it is imperative to understand the role of occupational safety in shaping officer behaviours. We assessed the longitudinal impact of police training in a quasi-experimental hybrid type-1 trial to reduce syringe-related occupational risk, while realigning police practices with public health prevention among people who inject drugs (PWID).

Setting

Tijuana, Mexico.

Participants

Of 1806 Tijuana municipal police trainees, 771 reporting previous exposure to syringes were randomly selected for follow-up. All participants completed at least one follow-up visit; attrition at 24 months was 8%.

Intervention

Between 2015 and 2016, officers received a training intervention (Safety and Health Integration in the Enforcement of Laws on Drugs, SHIELD) bundling occupational needle stick injury (NSI) prevention with health promotion among PWID.

Outcome measures

Longitudinal analysis with generalised linear mixed models to evaluate training impact on occupational NSI risk via NSI incidence and prevalidated Syringe Threat and Injury Correlates (STIC) score. This composite indicator integrates five self-reported risky syringe-handling practices (eg, syringe confiscation, breaking) and was used as a proxy for NSI risk due to reporting bias and concerns about reliability of NSI incidence reports.

Results

No change in self-reported NSI incidence was observed, but significant reductions in risk (16.2% decrease in STIC score) occurred at 3 months, with a sustained decrease of 17.8% through 24 months, compared with pretraining (p<0.001). Police assignment (patrol vs administration) moderated the training effect (p=0.01). Younger age, male gender, lower rank and previous NSI were independently and significantly associated with higher NSI risk overtime, although all groups demonstrated significant reductions post-training.

Conclusions

SHIELD is the first intervention to be associated with significant sustained changes in police practices that pose risk for both occupational and the public’s health. Integrating occupational safety and public health education should inform other interventions to mitigate the community health detriments of policing behaviours.

``Now it is mostly done through stashes, to do it in person one has to trust you'': Understanding the retail injection drug market in Dnipro, Ukraine

Little research has been conducted in Ukraine since the 1990s to understand the organization of drug market and its implications for people who inject drugs (PWID). In this study, we explore how PWID perceive the retail drug market in a large Ukrainian city. Qualitative data were obtained during in-depth interviews and analyses included open coding, coding tree development and revision, axial coding, and identification of higher-level domains. Participants' narratives focused on types and forms of drugs available, perceptions about drug quality, methods of buying drugs, and the relationships that are formed and maintained by participating in the drug economy. The described technical organization of the drug market, with multiple contingent combinations of drug types, forms and means of obtaining drugs (hand-to-hand vs stash-based) resulted from diversification and digitalization of the retail injection drug market. The social organization of the drug market in the form of relationships with sellers and drug use partners represented the response to the fundamental problem of uncertainty. The lens of ``transaction cost'' helps explain strategies PWID used to manage uncertainties, including finding reliable and suitable sellers, sending money and picking up the stash under the threat of being stiffed or caught by the police, choosing the product itself, using the intermediaries to outsource risky operations and forming groups to procure and inject together. Our results indicate that the technical and social organization of drug distribution in Ukraine stimulates formation and continuation of relationships and impacts the choices of what, how, and when to inject beyond individual preferences. The policy and practice implications include the need to monitor and understand the retail drug market to develop and deliver more efficient and client-oriented services, incorporate and leverage social networks structure for information sharing and behavior change, pilot and implement drug testing services to assist with management of uncertainties.

Preferences and acceptability of law enforcement initiated referrals for people who inject drugs: a mixed methods analysis

BACKGROUND

Law enforcement officers (LEOs) come into frequent contact with people who inject drugs (PWID). Through service referrals, LEOs may facilitate PWID engagement in harm reduction, substance use treatment, and other health and supportive services. Little is known about PWID and LEO attitudes and concerns about service referrals, however. The objective of this mixed-methods study was to examine the alignment of service referral preferences and acceptability among PWID and LEOs in Tijuana, Mexico.

METHODS

We assessed service referral preferences and perceived likelihood of participation in health and social services, integrating data from structured questionnaires with 280 PWID and 306 LEOs, contextualized by semi-structured interviews and focus groups with 15 PWID and 17 LEOs enrolled in two parallel longitudinal cohorts in Tijuana, Mexico.

RESULTS

Among potential service referral options, both PWID (78%) and LEOs (88%) most frequently cited assistance with drug- and alcohol-use disorders. Over half of PWID and LEOs supported including harm reduction services such as syringe service programs, overdose prevention, and HIV testing. The majority of PWID supported LEO referrals to programs that addressed basic structural needs (e.g. personal care [62%], food assistance [61%], housing assistance [58%]). However, the proportion of LEOs (30-45%) who endorsed these service referrals was significantly lower (p <  0.01). Regarding referral acceptability, 71% of PWID reported they would be very likely or somewhat likely to make use of a referral compared to 94% of LEOs reporting that they thought PWID would always or sometimes utilize them. These results were echoed in the qualitative analysis, although practical barriers to referrals emerged, whereby PWID were less optimistic that they would utilize referrals compared to LEOs.

CONCLUSIONS

We identified strong support for LEO service referrals among both LEO and PWID respondents, with the highest preference for substance use treatment. LEO referral programs offer opportunities to deflect PWID contact with carceral systems while facilitating access to health and social services. However, appropriate investments and political will are needed to develop an evidence-based (integrated) service infrastructure.

The ecology of overdose mortality in Philadelphia

Fatal drug overdose represents a significant public health threat in Philadelphia, but substantial variation exists across its communities. This study uses negative binomial longitudinal regression to model ZIP code overdose fatalities over a seven-year period. Model covariates indicate that structural inequality, police arrest activity, and features of the built environment are associated with increased mortality across ZIP codes. Additionally, fatalities are spatially concentrated in select geographies of the city. These findings emphasize the pertinence of community ecological features in the production of stratified within-city health outcomes, and inform the geographic distribution of harm reduction interventions.

Policing Practices and Risk of HIV Infection Among People Who Inject Drugs

Drug-law enforcement constitutes a structural determinant of health among people who inject drugs (PWID). Street encounters between police and PWID (e.g., syringe confiscation, physical assault) have been associated with health harms, but these relationships have not been systematically assessed. We conducted a systematic literature review to evaluate the contribution of policing to risk of human immunodeficiency virus (HIV) infection among PWID. We screened MEDLINE, sociological databases, and gray literature for studies published from 1981 to November 2018 that included estimates of HIV infection/risk behaviors and street policing encounters. We extracted and summarized quantitative findings from all eligible studies. We screened 8,201 abstracts, reviewed 175 full-text articles, and included 27 eligible analyses from 9 countries (Canada, China, India, Malaysia, Mexico, Russia, Thailand, Ukraine, and the United States). Heterogeneity in variable and endpoint selection precluded meta-analyses. In 5 (19%) studies, HIV infection among PWID was significantly associated with syringe confiscation, reluctance to buy/carry syringes for fear of police, rushed injection due to a police presence, fear of arrest, being arrested for planted drugs, and physical abuse. Twenty-one (78%) studies identified policing practices to be associated with HIV risk behaviors related to injection drug use (e.g., syringe-sharing, using a "shooting gallery"). In 9 (33%) studies, policing was associated with PWID avoidance of harm reduction services, including syringe exchange, methadone maintenance, and safe consumption facilities. Evidence suggests that policing shapes HIV risk among PWID, but lower-income settings are underrepresented. Curbing injection-related HIV risk necessitates additional structural interventions. Methodological harmonization could facilitate knowledge generation on the role of police as a determinant of population health.

Addressing Police Occupational Safety During an Opioid Crisis: The Syringe Threat and Injury Correlates (STIC) Score

OBJECTIVE

To develop and validate syringe threat and injury correlates (STIC) score to measure police vulnerability to needlestick injury (NSI).

METHODS

Tijuana police officers (N = 1788) received NSI training (2015 to 2016). STIC score incorporates five self-reported behaviors: syringe confiscation, transportation, breaking, discarding, and arrest for syringe possession. Multivariable logistic regression was used to evaluate the association between STIC score and recent NSI.

RESULTS

Twenty-three (1.5%) officers reported NSI; higher among women than men (3.8% vs 1.2%; P = 0.007). STIC variables had high internal consistency, a distribution of 4.0, a mode of 1.0, a mean (sd) of 2.0 (0.8), and a median (interquartile range [IQR]) of 2.0 (1.2 to 2.6). STIC was associated with recent NSI; odds of NSI being 2.4 times higher for each point increase (P-value <0.0001).

CONCLUSIONS

STIC score is a novel tool for assessing NSI risk and prevention program success among police.

Adherence to Antiretroviral Therapy Among Incarcerated Persons with HIV: Associations with Methadone and Perceived Safety

With adequate support, people with HIV (PWH) may achieve high levels of adherence to antiretroviral therapy (ART) during incarceration. We examined factors associated with ART utilization and adherence among incarcerated PWH (N = 150) in Indonesia. ART utilization was positively associated with HIV status disclosure (adjusted odds ratio [aOR] = 5.5, 95% CI 1.2-24.1, p = 0.023), drug dependency (aOR = 3.9, 95% CI 1.2-12.6, p = 0.022), health service satisfaction (aOR = 3.2, 95% CI 1.7-6.2, p < 0.001), and perceived need for medical treatment (aOR = 1.6, 95% CI 1.1-2.5, p = 0.011), and negatively associated with chance locus of control (aOR = 0.3, 95% CI 0.1-0.7, p = 0.013). Most participants utilizing ART (74.5%) reported less than "perfect" ART adherence. ART adherence was independently associated with perceived personal safety (β = 0.21, 95% CI 0.01-0.40, p = 0.032) and methadone utilization (β = 0.84, 95% CI 0.10-1.67, p = 0.047). PWH receiving methadone had a sixfold higher adjusted odds of being highly-adherent to ART (aOR = 6.3, 95% CI 1.1-35.7, p = 0.036). Interventions that increase methadone utilization and personal safety may improve ART adherence among incarcerated PWH.

HIV, Drug Injection, and Harm Reduction Trends in Eastern Europe and Central Asia: Implications for International and Domestic Policy

PURPOSE OF REVIEW

Scaling up evidence-based HIV prevention strategies like opioid agonist therapies (OAT), syringe services programs (SSPs), and antiretroviral therapy (ART) to mitigate the harms of drug injection is crucial within Eastern Europe and Central Asia (EECA), the only region globally where HIV incidence and mortality are increasing.

RECENT FINDINGS

Though the proportion of new HIV cases directly attributable to drug injection has recently declined, it remains a critical driver of HIV, especially to sexual partners. Concurrently, scale-up of OAT, SSPs, and ART has remained low, contributing to a volatile HIV epidemic among people who inject drugs (PWID). Despite evidence that drug injection contributes to an evolving HIV epidemic in EECA, coverage of evidence-based harm reduction programs remains substantially below needed targets. Due to a combination of punitive drug laws, ideological resistance to OAT among clinicians and policymakers, and inadequate domestic and international funding, limited progress has been observed in increasing the availability of these programs.

Police violence among people who inject drugs in Baltimore, Maryland

BACKGROUND

Police violence is a deleterious public health and criminal justice issue that disproportionately affects people who inject drugs (PWID). Studies documenting the prevalence and correlates of physical police violence in this population are rare. The aim of this study was to examine the correlates of past year physical police violence among an urban sample of PWID.

METHODS

PWID participating in the 2015 wave of the National HIV Behavioral Surveillance (NHBS) system in Baltimore City, Maryland, completed a socio-behavioral survey. Multivariable logistic regression was used to detect the socio-demographic, place-based, law-enforcement and health behavior correlates of exposure to police violence as well as knowledge of violence directed towards other PWID.

RESULTS

Enrolled PWID (N = 570) were mostly male (72%), non-Hispanic Black (77%) and daily heroin injectors (86%). Seven percent had experienced past year physical police violence (Respondent-Driven Sampling [RDS] weighted estimate: 4%), and a quarter (24%) knew someone who had experienced physical police violence in the past year (RDS-weighted estimate: 17%). Male gender, homelessness, arrest, drug paraphernalia confiscation, and receptive syringe sharing were independently associated with police violence. Knowing someone who had experienced police violence was independently correlated with selling drugs, arrest, and attending a syringe services program.

CONCLUSION

Population differences in the extent of police violence exposure indicate that experiences of police violence are not uniform among PWID. Violent encounters with police were associated with disruptions in harm reduction strategies that can prevent HIV and HCV transmission. This study adds to the small body of public health literature on police violence and highlights the importance of monitoring and addressing this critical issue.

Peer-to-peer injection: Demographic, drug use, and injection-related risk factors

BACKGROUND

Peer-to-peer injection (either providing or receiving an injection to/from a person who injects drugs [PWID]) is common (19%-50%) among PWID. Most studies of peer-to-peer injection have focused on receiving injection assistance, with fewer examining providing injection assistance and none considering characteristics of PWID who do both. We examined characteristics of PWID by peer-to-peer injection categories (receiving, providing, both, and neither) and determined if these behaviors were associated with receptive and distributive syringe sharing.

METHODS

Los Angeles and San Francisco PWID (N = 777) were recruited using targeted sampling methods and interviewed during 2011-2013. Multinomial logistic regression was used to determine characteristics associated with peer-to-peer injection categories and logistic regression was used to examine if peer-to-peer categories were independently associated with distributive and receptive syringe sharing.

RESULTS

Recent peer-to-peer injection was reported by 42% of PWID (18% provider; 14% recipient; 10% both). In multinomial regression analysis, PWID reporting any peer-to-peer injection were more likely to inject with others than those who did neither. Injection providers and those who did both were associated with more frequent injection, illegal income source, and methamphetamine injection while injection recipients were associated with fewer years of injection. Injection providers were younger, had more years of injecting, and were more likely to inject heroin than PWID who did neither. In multivariate analyses, we found that providers and PWID who did both were significantly more likely to report receptive and distributive syringe sharing than PWID who did neither.

CONCLUSION

Peer-to-peer injection is associated with HIV/HCV risk. Current prevention strategies may not sufficiently address these behaviors. Modification of existing interventions and development of new interventions to better respond to peer-to-peer injection is urgently needed.

Differences by sex in associations between injection drug risks and drug crime conviction among people who inject drugs in Almaty, Kazakhstan

BACKGROUND

The criminalization of drug use leads to high rates of drug crime convictions for engaging in injection drug use behaviors, introducing barriers to HIV prevention and drug treatment for PWID. Females (FWID) face unique vulnerabilities to HIV compared to males (MWID) in Kazakhstan. This study examined sex differences in associations between HIV/HCV infection, HIV knowledge, injection drug risk behaviors, and conviction for a drug crime in a sample of people who inject drugs (PWID) in Almaty, Kazakhstan.

METHODS

Analyses were performed on baseline data from 510 PWID and stratified by males (MWID) (329) and females (FWID) (181) from Kazakhstan in a couples-focused HIV prevention intervention. Logistic regression analyses using mixed effects (AOR) examined associations between HIV/HCV infection, HIV knowledge, injection drug risk behaviors, drug use severity, drug treatment history and conviction for a drug crime.

RESULTS

About three quarters of PWID reported drug crime conviction (73.92%, n = 377). HCV infection was associated with increased odds of drug crime conviction for FWID (AOR = 4.35, CI95 = 1.83-10.31, p < .01) and MWID (AOR = 3.62, CI95 = 1.09-12.07, p < .01). HIV transmission knowledge was associated with increased odds of conviction for MWID (AOR = 1.19, CI95 = 1.00-1.41, p < .05). Injection drug risk knowledge was associated with lower odds of conviction (AOR = .75, CI95 = .59-.94, p < .05) for FWID. Receptive syringe sharing (AOR = 3.48, CI95 = 1.65-7.31, p < .01), splitting drug solutions (AOR = 4.12, CI95 = 1.86-7.31, p < .05), and injecting with more than two partners (AOR = 1.89, CI95 = 1.06-3.34, p < .05) was associated with increased odds of conviction for FWID. Receptive syringe or equipment sharing with intimate partners was associated with conviction for both MWID (AOR = 1.90, CI95 = 1.03-3.92, p < .05) and FWID (AOR = 1.95, CI95 = 1.02-3.70, p < .05). For FWID, injection drug use in public spaces was associated with conviction (AORME = 3.25, CI95 = 1.31-7.39, p < .01). Drug use severity was associated with increased odds of conviction for FWID (AOR = 1.29, CI95 = 1.09-1.53, p < .001) and MWID (AOR = 1.24, CI95 = 1.09-1.41, p < .001). Ever receiving drug treatment was associated with conviction for MWID (AOR = 2.31, CI95 = 1.32-4.12, p < .01).

CONCLUSION

High-risk behaviors, HCV infection and more severe substance use disorders are associated with drug crime conviction for PWID, particularly FWID. Structural interventions are necessary to increase the engagement of PWID with drug crime convictions in HIV prevention and substance abuse treatment.

Addressing ethical challenges in HIV prevention research with people who inject drugs

Despite recent advances in HIV prevention and treatment, high HIV incidence persists among people who inject drugs (PWID). Difficult legal and political environments and lack of services for PWID likely contribute to high HIV incidence. Some advocates question whether any HIV prevention research is ethically justified in settings where healthcare system fails to provide basic services to PWID and where implementation of research findings is fraught with political barriers. Ethical challenges in research with PWID include concern about whether research evidence will be translated into practice; concerns that research might exacerbate background risks; and ethical challenges regarding the standard of HIV prevention in research. While these questions arise in other research settings, for research with PWID, these questions are especially controversial. This paper analyses four ethical questions in determining whether research could be ethically acceptable: (1) Can researchers ensure that research does not add to the burden of social harms and poor health experienced by PWID? (2) Should research be conducted in settings where it is uncertain whether research findings will be translated into practice? (3) When best practices in prevention and care are not locally available, what standard of care and prevention is ethically appropriate? (4) Does the conduct of research in settings with oppressive policies constitute complicity? We outline specific criteria to address these four ethical challenges. We also urge researchers to join the call to action for policy change to provide proven safe and effective HIV prevention and harm reduction interventions for PWID around the world.

The law on the streets: Evaluating the impact of Mexico's drug decriminalization reform on drug possession arrests in Tijuana, Mexico

BACKGROUND

In 2009, Mexican Federal Government enacted "narcomenudeo" reforms decriminalizing possession of small amounts of drugs, delegating prosecution of retail drug sales to the state courts, and mandating treatment diversion for habitual drug users. There has been insufficient effort to formally assess the decriminalization policy's population-level impact, despite mounting interest in analagous reforms across the globe.

METHODS

Using a dataset of municipal police incident reports, we examined patterns of drug possession, and violent and non-violent crime arrests between January 2009 and December 2014. A hierarchical panel data analysis with random effects was conducted to assess the impact of narcomenudeo's drug decriminalization provision.

RESULTS

The reforms had no significant impact on the number of drug possession or violent crime arrests, after controlling for other variables (e.g. time trends, electoral cycles, and precinct-level socioeconomic factors). Time periods directly preceding local elections were observed to be statistically associated with elevated arrest volume.

CONCLUSIONS

Analysis of police statistics parallel prior findings that Mexico's reform decriminalizing small amounts of drugs does not appear to have significantly shifted drug law enforcement in Tijuana. More research is required to fully understand the policy transformation process for drug decriminalization and other structural interventions in Mexico and similar regional and international efforts. Observed relationship between policing and political cycles echo associations in other settings whereby law-and-order activities increase during mayoral electoral campaigns.

Measuring improvement in knowledge of drug policy reforms following a police education program in Tijuana, Mexico

Background

Mexico’s 2009 “narcomenudeo reform” decriminalized small amounts of drugs, shifting some drug law enforcement to the states and mandating drug treatment diversion instead of incarceration. Data from Tijuana suggested limited implementation of this harm reduction-oriented policy. We studied whether a police education program (PEP) improved officers’ drug and syringe policy knowledge, and aimed to identify participant characteristics associated with improvement of drug policy knowledge.

Methods

Pre- and post-training surveys were self-administered by municipal police officers to measure legal knowledge. Training impact was assessed through matched paired nominal data using McNemar’s tests. Multivariable logistic regression was used to identify predictors of improved legal knowledge, as measured by officers’ ability to identify conceptual legal provisions related to syringe possession and thresholds of drugs covered under the reform.

Results

Of 1750 respondents comparing pre- versus post training, officers reported significant improvement (p < 0.001) in their technical understanding of syringe possession (56 to 91%) and drug amounts decriminalized, including marijuana (9 to 52%), heroin (8 to 71%), and methamphetamine (7 to 70%). The training was associated with even greater success in improving conceptual legal knowledge for syringe possession (67 to 96%) (p < 0.001), marijuana (16 to 91%), heroin (11 to 91%), and methamphetamine (11 to 89%). In multivariable modeling, those with at least a high school education were more likely to exhibit improvement of conceptual legal knowledge of syringe possession (adjusted odds ratio [aOR] 2.6, 95% CI 1.4–3.2) and decriminalization for heroin (aOR 2.7, 95% CI 1.3–4.3), methamphetamine (aOR 2.2, 95% CI 1.4–3.2), and marijuana (aOR 2.5, 95% CI 1.6–4).

Conclusions

Drug policy reform is often necessary, but not sufficient to achieve public health goals because of gaps in translating formal laws to policing practice. To close such gaps, PEP initiatives bundling occupational safety information with relevant legal content demonstrate clear promise. Our findings underscore additional efforts needed to raise technical knowledge of the law among personnel tasked with its enforcement. Police professionalization, including minimum educational standards, appear critical for aligning policing with harm reduction goals.

Barriers to Access to Sterile Syringes as Perceived by Pharmacists and Injecting Drug Users: Implications for Harm Reduction in Lebanon

BACKGROUND

Access to sterile syringes to injecting drug users (IDU) reduces sharing behavior and prevents the transmission of HIV.

OBJECTIVES

To describe the barriers to access to sterile syringes for IDUs in Lebanon from the perspectives of pharmacists and IDUs.

METHODS

in this qualitative study conducted in Lebanon, data were collected from 72 syringe purchase tests at pharmacies, 64 interviewees with pharmacists and 2 focus groups with injecting drug users. Two independent researchers analyzed the verbatim transcripts.

RESULTS

Results revealed that pharmacists often deny access to sterile syringes to IDUs who are frequently stigmatized and intimidated at pharmacies. While no large gender differences in pharmacists' attitudes and practices were observed, inequalities in syringe access were noticed with men IDUs more often denied purchase. Pharmacists had several barriers to sell syringes to IDUs including fear of disease spread, increased drug use, inappropriately discarded syringes, staff and customer safety, and business concerns. IDUs had several challenges to purchase syringes including stigmatization, intimidation, physical harassment, concern to reveal identity, fear of arrest and syringe price abuse.

CONCLUSIONS

Identifying the barriers to and facilitators of access to sterile syringes to IDUs is important to guide the development of efficient policies. Findings implicate the importance of empowering IDUs to purchase syringes at pharmacies through reducing the negative attitude towards IDUs and strengthening pharmacists' role in the promotion of health of IDUs. Findings also suggest that the habit of syringe sharing would decrease if the legal and cultural barriers to access are reduced.

Enduring Consequences From the War on Drugs: How Policing Practices Impact HIV Risk Among People Who Inject Drugs in Baltimore City

BACKGROUND

Neighborhood-level characteristics, including police activity, are associated with HIV and Hepatitis C injection risk-behaviors among people who inject drugs (PWID). However, the pathways through which these neighborhood perceptions shape individual-level HIV risk behaviors are unclear. This study helps to explain perceived behaviors between perceived neighborhood police activity and HIV injection risk behavior (i.e., injection syringe/tool sharing in the previous 6 months).

METHODS

A sample of (n = 366) PWIDs who self-reported recent use were recruited using community-based outreach methods in Baltimore, Maryland. Neighborhood police perceptions were assessed by asking participants whether they would (1) be more likely to ask others to share injection tools in the context of heightened police activity and (2) be less likely to carry syringes with them due to fear of arrest. Poisson regression with robust variance was used to identify statistical relationships. Recent police encounters, frequency of heroin injection, and sociodemographic characteristics were controlled for in the model.

RESULTS

Neighborhood police perceptions shaped injection-risk behavior. Half of the sample (49%) reported an aversion of carrying personal syringes, due to fear of arrest. Those who agreed they would be more likely to ask others to share injection equipment in the context of heightened police activity were more likely to share syringes (21% vs. 3%, p <.01). Adjusted models showed that syringe sharing was independently associated with asking to borrow equipment in neighborhoods with perceived heightened police activity (aPR: 2.22, 95% confidence interval (CI): 1.7, 3.0).

CONCLUSION

This study sheds light on how police perceptions may influence injection risk behavior. While these relationships require further elucidation, this study suggests that public health interventions aiming to reduce HIV risk would benefit from improving community-police relationships.

Punitive laws, key population size estimates, and Global AIDS Response Progress Reports: An ecological study of 154 countries

INTRODUCTION

UN global plans on HIV/AIDS have committed to reducing the number of countries with punitive laws criminalizing key populations. This study explores whether punitive laws are associated with countries' performance on targets set in the global plans.

METHODS

The study used chi-square tests of independence to explore associations between legal status, key population size estimates, and HIV service coverage for 193 countries from 2007 to 2014. We used data reported by countries on United Nations Global AIDS Progress Report (GARPR) indicators, and legal data from UNAIDS, UNDP, and civil society organizations. Due to lack of sufficiently reliable legal data, only men who have sex with men (MSM) could be studied. The study utilized public data aggregated at the national level. Correspondence with individual experts in a subset of countries stated the purpose of the study, and all responses were anonymized.

RESULTS AND DISCUSSION

A significantly larger proportion of countries that criminalize same-sex sexual behaviour reported implausibly low size estimates or no size estimates for MSM. This is consistent with findings in qualitative research that MSMs are marginalized and reluctant to be studied in countries where same-sex sexuality is criminalized. Size estimates are often used as the denominators for national HIV service coverage reports. Initially, countries that criminalized same-sex sexuality appeared to have higher HIV testing coverage among MSM than did countries where it is not criminalized. However, investigation of a subset of countries that have reported 90-100% HIV testing coverage among MSM found that most were based on implausibly low or absent size estimates.

CONCLUSION

Criminalization of same-sex sexuality is associated with implausibly low or absent MSM size estimates. Low size estimates may contribute to official denial of the existence of MSM; to failure to adequately address their needs; and to inflated HIV service coverage reports that paint a false picture of success. To enable and measure progress in the HIV response, UN agencies should lead a collaborative process to systematically, independently and rigorously gather data on laws and their enforcement.

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

Despite global reductions in HIV incidence and mortality, the 15 UNAIDS-designated countries of Eastern Europe and Central Asia (EECA) that gained independence from the Soviet Union in 1991 constitute the only region where both continue to rise. HIV transmission in EECA is fuelled primarily by injection of opioids, with harsh criminalisation of drug use that has resulted in extraordinarily high levels of incarceration. Consequently, people who inject drugs, including those with HIV, hepatitis C virus, and tuberculosis, are concentrated within prisons. Evidence-based primary and secondary prevention of HIV using opioid agonist therapies such as methadone and buprenorphine is available in prisons in only a handful of EECA countries (methadone or buprenorphine in five countries and needle and syringe programmes in three countries), with none of them meeting recommended coverage levels. Similarly, antiretroviral therapy coverage, especially among people who inject drugs, is markedly under-scaled. Russia completely bans opioid agonist therapies and does not support needle and syringe programmes-with neither available in prisons-despite the country's high incarceration rate and having the largest burden of people with HIV who inject drugs in the region. Mathematical modelling for Ukraine suggests that high levels of incarceration in EECA countries facilitate HIV transmission among people who inject drugs, with 28-55% of all new HIV infections over the next 15 years predicted to be attributable to heightened HIV transmission risk among currently or previously incarcerated people who inject drugs. Scaling up of opioid agonist therapies within prisons and maintaining treatment after release would yield the greatest HIV transmission reduction in people who inject drugs. Additional analyses also suggest that at least 6% of all incident tuberculosis cases, and 75% of incident tuberculosis cases in people who inject drugs are due to incarceration. Interventions that reduce incarceration itself and effectively intervene with prisoners to screen, diagnose, and treat addiction and HIV, hepatitis C virus, and tuberculosis are urgently needed to stem the multiple overlapping epidemics concentrated in prisons.

Confronting the HIV, Tuberculosis, Addiction, and Incarceration Syndemic in Southeast Asia: Lessons Learned from Malaysia

Throughout Southeast Asia, repressive drug laws have resulted in high rates of imprisonment in people who inject drugs (PWID) and people living with HIV (PLH), greatly magnifying the harm associated with HIV, tuberculosis, and addiction. We review findings from Malaysia's largest prison to describe the negative synergistic effects of HIV, tuberculosis, addiction, and incarceration that contribute to a 'perfect storm' of events challenging public and personal health and offer insights into innovative strategies to control these converging epidemics. The majority of PLH who are imprisoned in Malaysia are opioid dependent PWID. Although promoted by official policy, evidence-based addiction treatment is largely unavailable, contributing to rapid relapse and/or overdose after release. Similarly, HIV treatment in prisons and compulsory drug treatment centers is sometimes inadequate or absent. The prevalence of active tuberculosis is high, particularly in PLH, and over 80 % of prisoners and prison personnel are latently infected. Mandatory HIV testing and subsequent segregation of HIV-infected prisoners increases the likelihood of tuberculosis acquisition and progression to active disease, amplifying the reservoir of infection for other prisoners. We discuss strategies to control these intersecting epidemics including screening linked to standardized treatment protocols for all three conditions, and effective transitional programs for released prisoners. For example, recently introduced evidence-based interventions in prisons like antiretroviral therapy (ART) to treat HIV, isoniazid preventive therapy to treat latent tuberculosis infection, and methadone maintenance to treat opioid dependence, have markedly improved clinical care and reduced morbidity and mortality. Since introduction of these interventions in September 2012, all-cause and HIV-related mortality have decreased by 50.0 % and 75.7 %, respectively. We discuss the further deployment of these interventions in Malaysian prisons.

Factors associated with physical and sexual violence by police among people who inject drugs in Ukraine: implications for retention on opioid agonist therapy

Introduction

Ukraine's volatile HIV epidemic, one of the largest in Eastern Europe and Central Asia, remains concentrated in people who inject drugs (PWID). HIV prevalence is high (21.3% to 41.8%) among the estimated 310,000 PWID. Opioid agonist therapy (OAT) is the most cost-effective HIV prevention strategy there, yet OAT services are hampered by negative attitudes and frequent harassment of OAT clients and site personnel by law enforcement. This paper examines the various types of police violence that Ukrainian PWID experience and factors associated with the different types of violence, as well as the possible implications of police harassment on OAT retention.

Methods

In 2014 to 2015, we conducted a cross-sectional survey in five Ukrainian cities with 1613 PWID currently, previously and never on OAT, using a combination of respondent-driven sampling, as well as random sampling. We analysed correlates of police violence by multiple factors, including by gender, and their effects on duration of OAT retention. Self-reported physical and sexual violence by police were the two primary outcomes, while retention on OAT was used as a secondary outcome.

Results

Overall, 1033 (64.0%) PWID reported being physically assaulted by police, which was positively correlated with currently or previously being on OAT (69.1% vs. 60.2%; p<0.01). HIV prevalence rates were higher in those receiving OAT than those not on OAT (47.6% vs. 36.1%; p<0.01). Police violence experiences differed by sex, with men experiencing significantly more physical violence, while women experienced more sexual violence (65.9% vs. 42.6%; p<0.01). For PWID who had successfully accessed OAT, longer OAT retention was significantly correlated both with sexual assault by police and fewer non-fatal overdoses.

Conclusions

Police violence is a frequent experience among PWID in Ukraine, particularly for those accessing OAT, an evidence-based primary and secondary HIV prevention strategy. Police violence experiences, however, were different for men and women, and interventions with police that address these sexual differences and focus on non-violent interactions with PWID to improve access and retention on OAT are crucial for improving HIV prevention and treatment goals for Ukraine.

Pre-incarceration police harassment, drug addiction and HIV risk behaviours among prisoners in Kyrgyzstan and Azerbaijan: results from a nationally representative cross-sectional study

Introduction

The expanding HIV epidemic in Azerbaijan and Kyrgyzstan is concentrated among people who inject drugs (PWID), who comprise a third of prisoners there. Detention of PWID is common but its impact on health has not been previously studied in the region. We aimed to understand the relationship between official and unofficial (police harassment) detention of PWID and HIV risk behaviours.

Methods

In a nationally representative cross-sectional study, soon-to-be released prisoners in Kyrgyzstan (N=368) and Azerbaijan (N=510) completed standardized health assessment surveys. After identifying correlated variables through bivariate testing, we built multi-group path models with pre-incarceration official and unofficial detention as exogenous variables and pre-incarceration composite HIV risk as an endogenous variable, controlling for potential confounders and estimating indirect effects.

Results

Overall, 463 (51%) prisoners reported at least one detention in the year before incarceration with an average of 1.3 detentions in that period. Unofficial detentions (13%) were less common than official detentions (41%). Optimal model fit was achieved (X²=5.83, p=0.44; Goodness of Fit Index (GFI) GFI=0.99; Comparative Fit Index (CFI) CFI=1.00; Root Mean Square Error of Approximation (RMSEA) RMSEA=0.00; PCLOSE=0.98) when unofficial detention had an indirect effect on HIV risk, mediated by drug addiction severity, with more detentions associated with higher addiction severity, which in turn correlated with increased HIV risk. The final model explained 35% of the variance in the outcome. The effect was maintained for both countries, but stronger for Kyrgyzstan. The model also holds for Kyrgyzstan using unique data on within-prison drug injection as the outcome, which was frequent in prisoners there.

Conclusions

Detention by police is a strong correlate of addiction severity, which mediates its effect on HIV risk behaviour. This pattern suggests that police may target drug users and that such harassment may result in an increase in HIV risk-taking behaviours, primarily because of the continued drug use within prisons. These findings highlight the important negative role that police play in the HIV epidemic response and point to the urgent need for interventions to reduce police harassment, in parallel with interventions to reduce HIV transmission within and outside of prison.

Sex work and HIV incidence among people who inject drugs

OBJECTIVE

Although the global burden of HIV infection among sex workers (SW) has been well recognized, HIV-related risks among sex workers who inject drugs (SW-IDU) have received less attention. We investigated the relationship between sex work and HIV incidence among people who inject drugs (IDU) in a Canadian setting.

DESIGN

Prospective cohort study.

METHODS

Using Kaplan-Meier methods and the extended Cox regression, we compared HIV incidence among SW-IDU and non-SW-IDU in Vancouver, Canada, after adjusting for potential confounders.

RESULTS

Between 1996 and 2012, 1647 participants were included in the study, including 512 (31.1%) IDU engaged in sex work. At 5 years the HIV cumulative incidence was higher among SW-IDU in comparison to other IDU (12 vs. 7%, P = 0.001). In unadjusted Cox regression analyses, HIV incidence among SW-IDU was also elevated [relative hazard: 1.69; 95% confidence interval (CI): 1.13-2.53]. However, in a multivariable analysis, sex work did not remain associated with HIV infection (adjusted relative hazard: 0.74; 95% CI: 0.45-1.20), with cocaine injection appearing to account for the elevated risk for HIV infection among SW-IDU.

CONCLUSION

These data suggest that local SW-IDU have elevated rates of HIV infection. However, our exploration of risk factors among SW-IDU demonstrated that drug use patterns and environmental factors, rather than sexual risks, may explain the elevated HIV incidence among SW-IDU locally. Our findings highlight the need for social and structural interventions, including increased access to harm reduction programs and addiction treatment.

In Their Own Voices: Breaking the Vicious Cycle of Addiction, Treatment and Criminal Justice Among People who Inject Drugs in Ukraine

AIMS

To understand how perceived law enforcement policies and practices contribute to the low rates of utilization of opioid agonist therapies (OAT) among people who inject drugs (PWIDs) in Ukraine.

METHODS

Qualitative data from 25 focus groups (FGs) with 199 opioid-dependent PWIDs in Ukraine examined domains related to lived or learned experiences with OAT, police, arrest, incarceration, and criminal activity were analyzed using grounded theory principles.

FINDINGS

Most participants were male (66%), in their late 30s, and previously incarcerated (85%) mainly for drug-related activities. When imprisoned, PWIDs perceived themselves as being "addiction-free". After prison-release, the confluence of police surveillance, societal stress contributed to participants' drug use relapse, perpetuating a cycle of searching for money and drugs, followed by re-arrest and re-incarceration. Fear of police and arrest both facilitated OAT entry and simultaneously contributed to avoiding OAT since system-level requirements identified OAT clients as targets for police harassment. OAT represents an evidence-based option to 'break the cycle', however, law enforcement practices still thwart OAT capacity to improve individual and public health.

CONCLUSION

In the absence of structural changes in law enforcement policies and practices in Ukraine, PWIDs will continue to avoid OAT and perpetuate the addiction cycle with high imprisonment rates.

HIV Risks, Testing, and Treatment in the Former Soviet Union: Challenges and Future Directions in Research and Methodology

Background

The dissolution of the USSR resulted in independence for constituent republics but left them battling an unstable economic environment and healthcare. Increases in injection drug use, prostitution, and migration were all widespread responses to this transition and have contributed to the emergence of an HIV epidemic in the countries of former Soviet Union. Researchers have begun to identify the risks of HIV infection as well as the barriers to HIV testing and treatment in the former Soviet Union. Significant methodological challenges have arisen and need to be addressed. The objective of this review is to determine common threads in HIV research in the former Soviet Union and provide useful recommendations for future research studies.

Methods

In this systematic review of the literature, Pubmed was searched for English-language studies using the key search terms "HIV", "AIDS", "human immunodeficiency virus", "acquired immune deficiency syndrome", "Central Asia", "Kazakhstan", "Kyrgyzstan", "Uzbekistan", "Tajikistan", "Turkmenistan", "Russia", "Ukraine", "Armenia", "Azerbaijan", and "Georgia". Studies were evaluated against eligibility criteria for inclusion.

Results

Thirty-nine studies were identified across the two main topic areas of HIV risk and barriers to testing and treatment, themes subsequently referred to as "risk" and "barriers". Study design was predominantly cross-sectional. The most frequently used sampling methods were peer-to-peer and non-probabilistic sampling. The most frequently reported risks were condom misuse, risky intercourse, and unsafe practices among injection drug users. Common barriers to testing included that testing was inconvenient, and that results would not remain confidential. Frequent barriers to treatment were based on a distrust in the treatment system.

Conclusion

The findings of this review reveal methodological limitations that span the existing studies. Small sample size, cross-sectional design, and non-probabilistic sampling methods were frequently reported limitations. Future work is needed to examine barriers to testing and treatment as well as longitudinal studies on HIV risk over time in most-at-risk populations.

Behavioral and clinical characteristics of people receiving medical care for HIV infection in an outpatient facility in Sicily, Italy

AIM

The authors examined a cohort of HIV-positive outpatients at the AIDS Center of Palermo University in Italy in order to identify factors related to the frequency of their visits to the outpatient facility for health care services.

METHODS

Two hundred and twenty-four HIV-infected subjects were enrolled in the study. Demographic and HIV disease characteristics were recorded and assessed with the number of days accessed to our outpatients unit in univariate and multivariate analyses. The potential relationship with immunological status was also analyzed stratifying the patients into groups according to their CD4(+) T-cell counts (≥500 vs <500/mm(3), and ≥200 vs <200/mm(3)).

RESULTS

Both univariate and multivariate analyses showed that duration of antiretroviral therapy <5 years and hypertension were significantly associated with a CD4(+) T-cell count of <500/mm(3), whereas geographic origin (Africa) was associated with a CD4(+) T-cell count of <200/mm(3). Mean number of days the patients sought access to day-care services for laboratory tests was negatively associated with CD4(+) T-cell count.

CONCLUSION

Patients with low CD4(+) T-cell counts showed higher use of health care services, demonstrating how early HIV diagnosis can help to reduce health care costs. The CD4(+) T-cell cut-off of 200 cells emphasizes the importance of identifying and managing HIV infection among hard-to-reach groups like vulnerable migrants. In our sample, the illegal status of immigrants does not influence the management of their HIV/AIDS condition, but the lack of European health card that documents the current antiretroviral status, could interfere with the efforts to eradicate AIDS. A better understanding of the major determinants of HIV treatment costs has led to appropriate large-scale actions, which in turn has increased resources and expanded intervention programs. Further guidance should be offered to hard-to-reach groups in order to improve early AIDS diagnosis, and procedures for identifying and managing these vulnerable subjects should be made available to care commissioners and service providers.

Controlling HIV among people who inject drugs in Eastern Europe and Central Asia: insights from modeling

BACKGROUND

Although there is evidence of the effectiveness of needle and syringe programme (NSP), opioid substitution therapy (OST) and antiretroviral therapy (ART) in reducing HIV prevalence, most Central and Eastern European sub-regions still have low or no coverage of most or all of these interventions.

METHODS

We conducted a modelling analysis to consider the potential impact on HIV incidence and prevalence of OST, NSP and ART in three illustrative epidemic scenarios: Russia (St. Petersburg); Estonia (Tallinn) and Tajikistan (Dushanbe). For each intervention, we consider the coverage needed of each intervention separately or in combination to: (1) achieve a 30% or 50% relative reduction in HIV incidence or prevalence over 10 years; and (2) reduce HIV incidence to below 1% or HIV prevalence below 10% after 20 years. A sensitivity analysis for St. Petersburg considered the implications of greater on no risk heterogeneity, none or more sexual HIV transmission, like-with-like mixing, different injecting cessation rates and assuming a lower HIV acute phase cofactor.

RESULTS

For St. Petersburg, when OST, NSP and ART are combined, only 14% coverage of each intervention is required to achieve a 30% reduction in HIV incidence over 10 years. Similar findings are obtained for Tallinn and Dushanbe. In order to achieve the same reductions in HIV prevalence over 10 years, over double the coverage level is required relative to what was needed to achieve the same reduction in HIV incidence in that setting. To either reduce HIV incidence to less than 1% or HIV prevalence to less than 10% over 20 years, with all interventions combined, projections suggest that very high coverage levels of 74–85% are generally required for the higher prevalence settings of Tallinn and St. Petersburg, whereas lower coverage levels (23–34%) are needed in Dushanbe. Coverage requirements are robust to increased sexual HIV transmission, risk heterogeneity and like-with-like mixing, as well as to assuming a lower HIV acute phase cofactor or different injecting cessation rate.

CONCLUSION

The projections suggest that high but achievable coverage levels of NSP can result in large decreases (30%) in HIV incidence in settings with high HIV prevalence among PWID. Required coverage levels are much lower when interventions are combined or in lower prevalence settings. However, even when all three interventions are combined, the targets of reducing HIV incidence to less than 1% or prevalence to less than 10% in 20 years may be hard to achieve except in lower prevalence settings.

A "Common Factors" Approach to Developing Culturally Tailored HIV Prevention Interventions

The current dominant model of HIV prevention intervention dissemination involves packaging interventions developed in one context, training providers to implement that specific intervention, and evaluating the extent to which providers implement it with fidelity. Research shows that providers rarely implement these programs with fidelity due to perceived incompatibility, resource constraints, and preference for locally generated solutions. In this study, we used the concept of "common factors," or broad constructs shared by most evidence-based HIV prevention interventions, to train service providers to develop their own programs. We recruited eight Ukrainian HIV prevention organizations from regions with HIV epidemics concentrated among people who inject drugs. We trained staff to identify HIV risk behaviors and determinants, construct behavior change logic models, and develop and manualize an intervention. We systematically reviewed each manual to assess intervention format and content and determine whether the program met intervention criteria as taught during training. All agencies developed programs that reflected common factors of effective behavior change HIV prevention interventions. Each agency's program targeted a unique population that reflected local HIV epidemiology. All programs incorporated diverse pedagogical strategies that focused on skill-building, goal-setting, communication, and empowerment. Agencies struggled to limit information dissemination and the overall scope and length of their programs. We conclude that training service providers to develop their own programs based on common elements of effective behavior change interventions can potentially transform existing processes of program development, implementation, and capacity building. Expanding this model will require committed training and support resources.

A police education programme to integrate occupational safety and HIV prevention: protocol for a modified stepped-wedge study design with parallel prospective cohorts to assess behavioural outcomes

INTRODUCTION

Policing practices are key drivers of HIV among people who inject drugs (PWID). This paper describes the protocol for the first study to prospectively examine the impact of a police education programme (PEP) to align law enforcement and HIV prevention. PEPs incorporating HIV prevention (including harm reduction programmes like syringe exchange) have been successfully piloted in several countries but were limited to brief pre-post assessments; the impact of PEPs on policing behaviours and occupational safety is unknown.

OBJECTIVES

Proyecto ESCUDO (SHIELD) aims to evaluate the efficacy of the PEP on uptake of occupational safety procedures, as assessed through the incidence of needle stick injuries (NSIs) (primary outcome) and changes in knowledge of transmission, prevention and treatment of HIV and viral hepatitis; attitudes towards PWID, adverse behaviours that interfere with HIV prevention and protective behaviours (secondary outcomes).

METHODS/ANALYSIS

ESCUDO is a hybrid type I design that simultaneously tests an intervention and an implementation strategy. Using a modified stepped-wedge design involving all active duty street-level police officers in Tijuana (N = ∼ 1200), we will administer one 3 h PEP course to groups of 20-50 officers until the entire force is trained. NSI incidence and geocoded arrest data will be assessed from department-wide de-identified data. Of the consenting police officers, a subcohort (N=500) will be randomly sampled from each class to undergo pre-PEP and post-PEP surveys with a semiannual follow-up for 2 years to assess self-reported NSIs, attitudes and behaviour changes. The impact on PWIDs will be externally validated through a parallel cohort of Tijuana PWIDs.

ETHICS/DISSEMINATION

Research ethics approval was obtained from the USA and Mexico. Findings will be disseminated through open access to protocol materials through the Law Enforcement and HIV Network.

HIV Testing, Care, and Treatment Among Women Who Use Drugs From a Global Perspective: Progress and Challenges

The article reviews data on HIV testing, treatment, and care outcomes for women who use drugs in 5 countries across 5 continents. We chose countries in which the HIV epidemic has, either currently or historically, been fueled by injection and non-injection drug use and that have considerable variation in social structural and drug policies: Argentina, Vietnam, Australia, Ukraine, and the United States. There is a dearth of available HIV care continuum outcome data [ie, testing, linkage, retention, antiretroviral therapy (ART) provision, viral suppression] among women drug users, particularly among noninjectors. Although some progress has been made in increasing HIV testing in this population, HIV-positive women drug users in 4 of the 5 countries have not fully benefitted from ART nor are they regularly engaged in HIV care. Issues such as the criminalization of drug users, HIV-specific criminal laws, and the lack of integration between substance use treatment and HIV primary care play a major role. Strategies that effectively address the pervasive factors that prevent women drug users from engaging in HIV care and benefitting from ART and other prevention services are critical. Future success in enhancing the HIV continuum for women drug users should consider structural and contextual level barriers and promote social, economic, and legal policies that overhaul the many years of discrimination and stigmatization faced by women drug users worldwide. Such efforts must emphasis the translation of policies into practice and approaches to implementation that can help HIV-infected women who use drugs engage at all points of the HIV care continuum.

Policing behaviors, safe injection self-efficacy, and intervening on injection risks: Moderated mediation results from a randomized trial

OBJECTIVE

We aim to use conditional or moderated mediation to simultaneously test how and for whom an injection risk intervention was efficacious at reducing receptive needle sharing among female sex workers who inject drugs (FSWs-IDUs) in Mexico.

METHODS

Secondary analysis of data from a randomized trial. A total of 300 FSW-IDUs participated in Mujer Mas Segura in Ciudad Juarez, Mexico, and were randomized to an interactive injection risk intervention or a didactic injection risk intervention. We measured safe injection self-efficacy as the hypothesized mediator and policing behaviors (being arrested and syringe confiscation) as hypothesized moderators. In total, 213 women provided complete data for the current analyses.

RESULTS

Conditional (moderated) mediation showed that the intervention affected receptive needle sharing through safe injection self-efficacy among women who experienced syringe confiscation. On average, police syringe confiscation was associated with lower safe injection self-efficacy (p = .04). Among those who experienced syringe confiscation, those who received the interactive (vs. didactic) intervention reported higher self-efficacy, which in turn predicted lower receptive needle sharing (p = .04).

CONCLUSIONS

Whereas syringe confiscation by the police negatively affected safe injection self-efficacy and ultimately injection risk behavior, our interactive intervention helped to "buffer" this negative impact of police behavior on risky injection practices. The theory-based, active skills building elements included in the interactive condition, which were absent from the didactic condition, helped participants' self-efficacy for safer injection in the face of syringe confiscation.

Geographic variability in HIV and injection drug use in Ukraine: implications for integration and expansion of drug treatment and HIV care

BACKGROUND

Ukraine has the highest HIV burden of any European country with much of the current HIV epidemic concentrated among people who inject drugs (PWIDs) and their sexual partners. Opiate substitution therapy (OST) is limited in Ukraine and expansion of OST is urgently needed to help stem the tide of the HIV epidemic.

METHODS

We accessed publicly available data in Ukraine in order to explore geographic variability with respect to prevalence of HIV, PWIDs and OST programmes.

RESULTS

The regions of Ukraine with the largest number of opioid dependent persons (the south and eastern portions of the country) correspond to the regions with the highest HIV prevalence and HIV incidence. The number of opioid PWIDs per 100,000 population as well as the number of all OST treatment slots per 100,000 varied significantly across the three HIV prevalence categories. Overall, the proportion of individuals receiving either methadone maintenance therapy (MMT) or buprenorphine maintenance therapy (BMT) was quite low: average across categories: 7.3% and 0.4%, respectively. Additionally, less than half of OST patients receiving MMT or BMT were HIV positive patients.

CONCLUSION

There is significant geographic variability in both numbers of HIV positive individuals and numbers of PWIDs across Ukraine, however, there may be a more concentrated epidemic among PWIDs in many regions of the country. Scale up of addiction treatment for PWID, especially OST, can have a significant impact on preventing injection related morbidity, such as HIV and HCV infection. Ukraine can learn from the mistakes other nations have made in denying critical treatment opportunities to PWID.

Drug use as a driver of HIV risks: re-emerging and emerging issues

PURPOSE OF REVIEW

We reviewed the studies published in 2012-2013 that focused on re-emerging and emerging injection and noninjection drug use trends driving HIV risk behaviors and transmission in some parts of the world.

RECENT FINDINGS

Although HIV incidence has declined in many countries, HIV epidemics remain at troubling levels among key drug-using populations, including females who inject drugs (FWIDs), FWIDs who trade sex, sex partners of people who inject drugs, young people who inject drugs, and people who use noninjection drugs in a number of low-income and middle-income countries such as in Central Asia, Eastern Europe, Southeast Asia, and parts of Africa.

SUMMARY

HIV epidemics occur within the contexts of global economic and political forces, including poverty, human rights violations, discrimination, drug policies, trafficking, and other multilevel risk environments. Trends of injection and noninjection drug use and risk environments driving HIV epidemics in Central Asia, Eastern Europe, Southeast Asia, and parts of Africa call for political will to improve HIV and substance use service delivery, access to combination HIV prevention, and harm reduction programs.

HIV, drugs and the legal environment

A large body of scientific evidence indicates that policies based solely on law enforcement without taking into account public health and human rights considerations increase the health risks of people who inject drugs (PWIDs) and their communities. Although formal laws are an important component of the legal environment supporting harm reduction, it is the enforcement of the law that affects PWIDs' behavior and attitudes most acutely. This commentary focuses primarily on drug policies and policing practices that increase PWIDs' risk of acquiring HIV and viral hepatitis, and avenues for intervention. Policy and legal reforms that promote public health over the criminalization of drug use and PWID are urgently needed. This should include alternative regulatory frameworks for illicit drug possession and use. Changing legal norms and improving law enforcement responses to drug-related harms requires partnerships that are broader than the necessary bridges between criminal justice and public health sectors. HIV prevention efforts must partner with wider initiatives that seek to improve police professionalism, accountability, and transparency and boost the rule of law. Public health and criminal justice professionals can work synergistically to shift the legal environment away from one that exacerbates HIV risks to one that promotes safe and healthy communities.

Gender differences between predictors of HIV status among PWID in Ukraine

BACKGROUND

The HIV epidemic in Ukraine is among the largest in Europe. While traditionally the epidemic has spread through injection risk behavior, sexual transmission is becoming more common. Previous research has found that women in Ukraine have higher rates of HIV and engage in more HIV risk behavior than men. This study extended that work by identifying risk factors that differentially predict men and women's HIV status among people who inject drugs (PWID) in Ukraine.

METHODS

From July 2010 to July 2013, 2480 sexually active PWID with unknown HIV status were recruited from three cities in Ukraine through street outreach. The average age was 31 years old.

RESULTS

Women, who made up twenty-eight percent of the sample, had higher safe sex self-efficacy (p<.01) and HIV knowledge (p<.001) than men, but scored higher on both the risky injection (p<.001) and risky sex (p<.001) composite scores than men. Risky sex behaviors were associated with women's HIV status more than men's. We also report results identifying predictors of risky injection and sex behaviors.

CONCLUSIONS

Gender-specific interventions could address problem of HIV risk among women who inject drugs in a country with a growing HIV epidemic. Our findings suggest specific ways in which intervention efforts might focus on groups and individuals who are at the highest risk of contracting HIV (or who are already HIV positive) to halt the spread of HIV in Ukraine.
