Tonin FS, Alves da Costa F, Fernandez-Llimos F. Impact of harm minimization interventions on reducing blood-borne infection transmission and some injecting behaviors among people who inject drugs: an overview and evidence gap mapping. Addict Sci Clin Pract 2024; 19:9. [PMID: 38310293 PMCID: PMC10838443 DOI: 10.1186/s13722-024-00439-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 01/18/2024] [Indexed: 02/05/2024] Open
Abstract
BACKGROUND This study aimed to synthetize the evidence on the effectiveness of harm minimization interventions on reducing blood-borne infection transmission and injecting behaviors among people who inject drugs (PWID) through a comprehensive overview of systematic reviews and evidence gap mapping. METHODS A systematic review was conducted with searches in PubMed and Scopus to identify systematic reviews assessing the impact of interventions aimed at reducing the harms associated with injectable drug use. The overall characteristics of the studies were extracted and their methodological quality was assessed using AMSTAR-2. An evidence gap map was constructed, highlighting the most frequently reported outcomes by intervention (CRD42023387713). RESULTS Thirty-three systematic reviews were included. Of these, 14 (42.2%) assessed the impact of needle/syringe exchange programs (NSEP) and 11 (33.3%) examined opioid agonist therapy (OAT). These interventions are likely to be associated with reductions of HIV/HCV incidence (10-40% risk reduction for NSEP; 50-60% for OAT) and sharing injecting paraphernalia (50% for NSEP, 25-85% for OAT), particularly when combined (moderate evidence). Behavioral/educational interventions were assessed in 12 reviews (36.4%) with most authors in favor/partially in favor of the use of these approaches (moderate evidence). Take-home naloxone programs and supervised-injection facilities were each assessed in two studies (6.1%), which reported inconclusive results (limited/inconsistent evidence). Most authors reported high levels of heterogeneity and risk of bias. Other interventions and outcomes were inadequately reported. Most systematic reviews presented low or critically low quality. CONCLUSION The evidence is sufficient to support the effectiveness of OAT, NSEP and their combination in reducing blood-borne infection transmission and certain injecting behaviors among PWID. However, evidence of other harm minimizations interventions in different settings and for some outcomes remain insufficient.

Abstract
BACKGROUND AND AIMS Hepatitis C virus (HCV) is a prominent liver disease that often presents with mental illness. We stratify the HCV population and review its healthcare burden on the US hospital system. METHODS The US National Inpatient Sample was used to select admissions related to HCV between 2016 and 2019. Weights were assigned to discharges, and trend analyses were performed. Strata were formed across demographics, comorbidities, psychiatric and substance use conditions, and other variables. Outcomes of interest included hospitalization incidences, mortality rates, total costs, and mean per-hospitalization costs. RESULTS From 2016 to 2019, there were improvements in mortality and hospitalization incidence for HCV, as well as a decline in aggregate costs across the majority of strata. Exceptions that showed cost growth included admissions with multiple psychiatric, stimulant use, or poly-substance use disorders, and a history of homelessness. Admissions with no psychiatric comorbidities, admissions with no substance use comorbidities, and admissions with housing and without HIV comorbidity showed decreasing total costs. Along with per-capita mean costs, admissions with comorbid opioid use, bipolar, or anxiety disorder showed significant increases. No significant trends in per-capita costs were found in admissions without mental illness diagnoses. CONCLUSIONS Most strata demonstrated decreases in hospitalization incidences and total costs surrounding HCV; however, HCV cases with mental illness diagnoses saw expenditure growth. Cost-saving mechanisms for these subgroups are warranted.

Assessment of Tennessee's county-level vulnerability to hepatitis C virus and HIV outbreaks using socioeconomic, healthcare, and substance use indicators. PLoS One 2022; 17:e0270891. [PMID: 35925969 PMCID: PMC9352017 DOI: 10.1371/journal.pone.0270891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Accepted: 06/19/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Human immunodeficiency virus (HIV), hepatitis C virus (HCV), and injection drug use are syndemic in the central Appalachian states. In Tennessee (TN), declines in HIV among persons who inject drugs (PWID) stalled, and HCV infection rates increased significantly from 2013-2017. To better target strategies to address the syndemic, county-level socioeconomic, opioid use, access to healthcare, and health factors were modeled to identify indicators predictive of vulnerability to an HIV/HCV outbreak among PWID in TN. METHODS Newly reported chronic HCV cases among persons aged 13-39 years in 2016-2017 were used as a proxy for county-level HIV/HCV vulnerability among TN's 95 counties. Seventy-five publicly available county-level measures from 2016-2017 were collected and reduced through multiple dimension reduction techniques. Negative binomial regression identified indicators associated with HCV which were used to calculate county-level vulnerability to a local HIV/HCV outbreak. RESULTS Thirteen county-level indicators were identified as strongly predictive of HIV/HCV vulnerability with the statistically significant indicators being percentage of the population aged 20-44 years, per capita income, teen birth rate, percentage of clients in TDMHSAS-funded opioid treatment and recovery, syphilis case rate, and percentage of homes with at least one vehicle. Based on the 13 indicators, we identified the distribution of vulnerability to an HIV/HCV outbreak among TN's counties. Eleven high vulnerability counties were identified, with the preponderance located in east and middle TN. CONCLUSION This analysis identified the county-level factors most associated with vulnerability to an HIV/HCV outbreak among PWID in TN. These results, alongside routine surveillance, will guide targeted prevention and linkage to care efforts for the most vulnerable communities.

Abstract
BACKGROUND The dynamics of injection drug use and higher-risk sexual practices compound the risk of HIV and HCV acquisition. Published literature on people who inject drugs (PWID) has examined risk of infection assuming homogeneity of cohort behavior. Categorizing subgroups by injection and sexual risk can inform a more equitable approach to how syringe services programs (SSPs) adapt harm reduction resources and implementation of evidence-based interventions. We explored injection and sexual risk profiles among PWID to determine significant predictors of class membership. METHODS Data were collected from 1,272 participants at an SSP in Miami-Dade County. Latent Class Analysis (LCA) examined how 10 injection/sexual behavior indicators cluster together to create profiles. Model fit statistics and multivariable multinomial latent class regression identified the optimal class structure and significant predictors of class membership. We assessed SSP visits, naloxone access, HIV/HCV testing and prevalence, and incidence of self-reported wounds. RESULTS Three distinct profiles of injection/sexual risk were determined: Low Injection/High Sexual (LIHS) (9.4%); High Injection/Moderate Sexual (HIMS) (18.9%); and Low Injection/Low Sexual (LILS) (71.7%). Participants reporting gay/bisexual orientation and methamphetamine injection more likely belonged to the LIHS class. LIHS class members had higher prevalence of HIV, while those of HIMS reported increased hepatitis C prevalence. Compared to members of LILS, those of HIMS more likely experienced unstable housing, gay/bisexual orientation, heroin or speedball injection, and identifying as women. HIMS cohort members had more SSP visits, naloxone accessed, and higher wound incidence than those of LILS. CONCLUSIONS Understanding PWID subgroups amplifies the importance of implementing evidencebased interventions such as PrEP for those engaging in highest risk behavior, with focused interventions of antiretroviral management and access to condoms for members of the LIHS class and HCV screening with wound care for those belonging to HIMS.

Acceptability, feasibility, and pilot results of the tele-harm reduction intervention for rapid initiation of antiretrovirals among people who inject drugs. Drug Alcohol Depend 2021; 229:109124. [PMID: 34781096 PMCID: PMC9102418 DOI: 10.1016/j.drugalcdep.2021.109124] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 09/16/2021] [Accepted: 09/25/2021] [Indexed: 01/12/2023]
Abstract
BACKGROUND People who inject drugs (PWID) have been a marginalized and a stigmatized population since the beginning of the AIDS epidemic and have not experienced the same life-changing benefits of antiretroviral therapy as others. Tele-Harm Reduction (THR) is a telehealth-enhanced, harm reduction intervention, delivered within a trusted SSP venue. It aims to facilitate initiation of care and achieve rapid HIV viral suppression among PWID living with HIV. METHODS In this mixed-methods study, we employed the Practical, Robust, Implementation and Sustainability Model (PRISM) implementation science framework to identify multilevel barriers and facilitators to implementing the THR intervention. Focus groups (n = 2, 16 participants), stakeholder interviews (n = 7) and in-depth interviews were conducted with PWID living with HIV (n = 25). In addition, to assess feasibility and acceptability, we pilot tested the THR intervention and reported viral suppression at 6 months. RESULTS Focus groups and stakeholder interviews revealed system and organizational level barriers to implementation including requirements for identification and in person visits, waiting times, stigma, case management inexperience, multiple electronic health records, and billing. A potential facilitator was using telehealth for case management and initial provider visit. In the in depth interviews conducted with PWID living with HIV, participants expressed that the SSP creates a convenient, comfortable, confidential environment for delivering multiple, non-stigmatizing PWID-specific services. 35 PWID living with HIV were enrolled in the pilot study, 35 initiated antiretroviral therapy, and 25 (78.1%) were virally suppressed at six months. CONCLUSION Rooted in harm reduction, the THR intervention shows promise in being an acceptable and feasible intervention that may facilitate engagement in HIV care and viral suppression among PWID.

Abstract
BACKGROUND Syringe services programs (SSPs) remain highly effective, cost-saving interventions for the prevention of blood-borne infections among people who inject drugs. However, there have been restrictions regarding financial resources allocated to these programs, particularly in the US South. This study aimed to provide cost data regarding the implementation and first-year operations of an academic-based SSP utilizing fixed and mobile strategies, including the integration of onsite wound care. METHODS We conducted a micro-costing study that retrospectively collected detailed resource utilization and unit cost data for both the fixed and mobile SSP strategies, including onsite wound care, from both healthcare and societal perspectives. A three-step approach was used to identify, measure, and value intervention costs, and cost components were categorized into implementation, variable program, and time-dependent costs. Sensitivity analysis was performed to examine the impact of SSP operational changes (i.e., needs-based distribution and opt-out HIV/HCV testing) on the cost-per-participant. Cost data we presented as overall cost and cost-per-participant adjusted to 2017 US dollars. RESULTS A total of 452 and 129 participants enrolled in fixed and mobile SSP services, respectively. The total cost associated with implementation and first year operations for the fixed site was $407,217.22 or $729.72 per participant and $311,625.52 or $2415.70 per participant for the mobile unit. The largest cost component for both modalities was time-dependent costs (personnel and overhead), while intervention materials (syringes, injection equipment, naloxone) were less than 15% of the total program cost. DISCUSSION/CONCLUSION Implementation and operation of new SSP models continue to be low cost compared to treatment for the multitude of harms PWID face without access to evidence-based prevention. Future cost-effectiveness and cost-benefit analyses integrating a comprehensive SSP model within an academic institution, including onsite wound care and other medical services, will provide a more comprehensive understanding of this model, and state-level policy action must be taken to lift the prohibition of state and local funds for the implementation, sustainability, and maintenance of these programs in Florida.

Abstract
Provision of sterile syringes is an evidence-based strategy of reducing syringe sharing and reusing and yet, access to sterile syringes through pharmacies and syringe exchange programs (SEPs) in the United States remains inadequate. This nationally representative study examined associations between obtaining syringes from pharmacies, SEPs, and sterilizing syringes with bleach and risk of syringe borrowing, lending and reusing syringes in a pooled cross-sectional dataset of 1737 PWID from the 2002-2019 National Survey on Drug Use and Health. Logistic regression was used to produce odds ratios (OR) of the odds of injection drug behaviors after adjusting for obtaining syringes from SEPs, pharmacies, the street, and other sources and potential confounders of race, ethnicity, sex, education, and insurance coverage. Obtaining syringes through SEPs was associated with lower odds of borrowing (OR = .4, CI95% = .2, .9, p = .022) and reusing syringes (OR = .3, CI95% = .2, .6, < .001) compared to obtaining syringes on the street. Obtaining syringes from pharmacies was associated with lower odds of borrowing (OR = .5, CI95% = .3, .9, p = .037) and lending (OR = .5 CI95% = .3, .9, p = .020) syringes. Using bleach to clean syringes was associated with increased odds of borrowing (OR = 2.0, CI95% = 1.3, 3.0, p = .002), lending (OR = 2.0, CI95% = 1.3, 3.0, p = .002) and reusing syringes (OR = 2.4, CI95% = 1.6, 3.6, p < .001). Our findings support provision of syringes through pharmacies and SEPs as a gold-standard strategy of reducing sharing and reuse of syringes in the US.

Abstract
BACKGROUND Drug use, specifically opioid use, is a public health crisis in the United States. Harm reduction programs, including syringe service programs, show efficacy in improving individual and public health outcomes. Healthcare provider perceptions are an important initial assessment when considering implementing a syringe service program. OBJECTIVE The objective of this quality improvement project, completed in a Northeastern Veterans Affairs Medical Center (NEVAMC), was to lay the groundwork for implementation of a syringe service program. METHODS This multiphase project included an initial needs assessment with stakeholders to determine the scope of substance use disorder within the facility and initiated the change process needed for syringe service program implementation. We administered an online survey, the Drug and Drug Problems Perceptions Questionnaire (DDPPQ), to better understand staff perspectives of and comfort in working with people who use drugs. Two educational modules were developed and conducted for staff to increase their knowledge, skills, and trauma-informed practices when working with people who use drugs. Standardized document templates for program implementation in federal systems were also developed. RESULTS The needs assessment identified 266 patients who could benefit from expanded harm reduction services and a recognition that staff perception be assessed within the facility. The DDPPQ, completed by 153 staff members, indicated positive perceptions of people who use drugs and ability to counsel/treat people who use drugs. The median DDPPQ total score was 73, indicative of an overall positive perception. Sixty-eight staff members attended the initial education session, and 35 attended the second session designed specifically for mental health service line professionals. CONCLUSION The findings indicate NEVAMC staff members have a high level of comfort working with people who use drugs. The staff educational programs were well received and have become a part of routine staff training at the NEVAMC. The standardized document templates are available for persons developing a syringe service program within a federal system.

Abstract
INTRODUCTION Syringe services programs (SSPs) are evidence-based HIV prevention programs for people who inject drugs. However, not all SSPs operate evidence-based syringe distribution models, such as needs-based distribution. This study aims to provide preliminary evidence from the IDEA SSP on changes in injection risk behaviors over time, and to examine factors, including syringe coverage, associated with injection risk behavior trajectories over time under a one-for-one syringe distribution model. METHODS We used a prospective observational study design to generate a cohort of SSP clients who completed three behavioral assessments at SSP service visits between December 2016 and January 2020 (N = 115). The study used generalized estimating equations (GEE) to examine the relationship between covariate measures and the primary outcomes. The primary outcomes were 1) sharing of any injection equipment (e.g. syringes, needles, cookers, cottons) in the previous 30 days (yes/no) and 2) reusing of needles/syringes in the previous 30 days (yes/no). RESULTS Men were more likely to report reusing syringes (aRR = 1.15, 95% CI: 1.01-1.37) and those who reported injecting in public were less likely to report reusing syringes (aRR = 0.90, 95% CI: 0.82-0.99). HCV-positive clients had a 62% reduction in sharing injection equipment and those who reported public injection had a 62% increase in sharing injection equipment over time. Most importantly, increasing syringe coverage was associated with a decrease in both sharing injection equipment (aRR = 0.42, 95% CI: 0.25-0.72) and reusing syringes (aRR = 0.79, 95% CI: 0.66-0.95). CONCLUSION This study provides preliminary evidence of reductions in injection-related risk behaviors from the IDEA SSP and highlights potential high priority groups, such as people experiencing homelessness, that may need additional intervention. In addition, improving syringe coverage among SSP clients may be an important factor in reducing behaviors that place individuals at risk for contracting HIV and HCV.

Abstract
BACKGROUND In 2018, Philadelphia identified an outbreak of new human immunodeficiency virus (HIV) infections among persons who inject drugs (PWID). Although conventional HIV surveillance systems capture individual-level behavioral risk, they are not able to capture the social and environmental factors contributing to rapid transmission. METHODS HIV surveillance data were used to assess demographic, clinical, and behavioral factors for PWID with HIV diagnosed during 2017 and 2018. Social factors such as homelessness, disruption of encampments, and trends in sexual behaviors, drug use and syringe availability among PWID were captured through National HIV Behavioral Surveillance, routine hepatitis and sexually transmitted infection surveillance, and shelter and homeless outreach data. RESULTS In 2018, there were 71 new infections among PWID, an increase of 115% since 2016. During this time, opioid overdose deaths peaked at 59 deaths per 100 000 persons, 85% of which involved the use of fentanyl. While overall reported homelessness increased, rates of those living unsheltered rose by 13%. The Philadelphia Department of Public Health identified increased injection frequency, encampment closures, and lack of syringe access as promoters of continued HIV transmission. CONCLUSION The use of conventional surveillance methods only is inadequate for determining HIV risk during outbreaks. Incorporation of individual and aggregate level data on social and environmental determinants is necessary to develop effective outbreak response interventions.

Abstract
We present the Progression and Transmission of HIV (PATH 4.0), a simulation tool for analyses of cluster detection and intervention strategies. Molecular clusters are groups of HIV infections that are genetically similar, indicating rapid HIV transmission where HIV prevention resources are needed to improve health outcomes and prevent new infections. PATH 4.0 was constructed using a newly developed agent-based evolving network modeling (ABENM) technique and evolving contact network algorithm (ECNA) for generating scale-free networks. ABENM and ECNA were developed to facilitate simulation of transmission networks for low-prevalence diseases, such as HIV, which creates computational challenges for current network simulation techniques. Simulating transmission networks is essential for studying network dynamics, including clusters. We validated PATH 4.0 by comparing simulated projections of HIV diagnoses with estimates from the National HIV Surveillance System (NHSS) for 2010-2017. We also applied a cluster generation algorithm to PATH 4.0 to estimate cluster features, including the distribution of persons with diagnosed HIV infection by cluster status and size and the size distribution of clusters. Simulated features matched well with NHSS estimates, which used molecular methods to detect clusters among HIV nucleotide sequences of persons with HIV diagnosed during 2015-2017. Cluster detection and response is a component of the U.S. Ending the HIV Epidemic strategy. While surveillance is critical for detecting clusters, a model in conjunction with surveillance can allow us to refine cluster detection methods, understand factors associated with cluster growth, and assess interventions to inform effective response strategies. As surveillance data are only available for cases that are diagnosed and reported, a model is a critical tool to understand the true size of clusters and assess key questions, such as the relative contributions of clusters to onward transmissions. We believe PATH 4.0 is the first modeling tool available to assess cluster detection and response at the national-level and could help inform the national strategic plan.

Abstract
BACKGROUND Predictors of syringe exchange behavior are critical to informing secondary prevention measures needed to attenuate risk of blood-borne infections among persons who inject drugs (PWID). METHODS Participants included PWIDs who attended a syringe services program in New York from 2015 to 2017 (n = 1777). We analyzed the syringe return ratio (receipts/returns) with two distinct but related methodological strategies-threshold logistic regression and quantile regression-to identify correlates of disparities in syringe return ratios. RESULTS The majority of participants were white males negative for HIV (90% white, 63% male, 76% HIV-). Logistic and quantile regression models showed that the correlates of disparate syringe return ratios (i.e., magnitude and directionality of differences) changed across different percentile groups and quantile levels, respectively. At the median threshold, being single, urbanicity, and older age were associated with higher return ratios. Syringe return ratio disparities were more pronounced among subgroups of nontypical PWIDs (with extremely low or high return ratios) especially by urbanicity, race, relationship status, and type of housing. CONCLUSIONS Irrespective of urbanicity classification, correlates of syringe return ratios such as older age, Black race, single relationship status, and unstable housing appear to be critical to informing targeted secondary prevention initiatives that promote harm reduction behavior.

Abstract
BACKGROUND People who inject drugs (PWID) around the world are disproportionately affected by the HIV epidemic. National policy responses to the epidemic heavily influence risk factors for HIV acquisition among this key group. Prior efforts to monitor national policy responses to HIV/AIDS among PWID were limited both in scope and coverage. In this paper we develop and validate the HIV-PWID Policy Index (HPPI) to benchmark and monitor national commitments to HIV prevention and treatment among PWID. METHODS Composite indicator was constructed employing fuzzy multilayer data envelopment analysis (FMLDEA). Model inputs based on data from 105 countries included 27 variables measured across six conceptual domains, including needle and syringe programs, opioid substitution treatment, testing and counseling, information and education, monitoring and evaluation, and legal and policy climate. RESULTS According to the HPPI, which ranges from 0 to 1, the top performing countries in policy commitments to HIV prevention and treatment among PWID were Spain (0.988), Switzerland (0.982), Luxembourg (0.970), Moldova (0.970), and Kyrgyzstan (0.945), whereas the poorest performing included Nicaragua (0.094), Japan, (0.094), Cape Verde (0.097), Syria (0.174), and Benin (0.185). Regionally, commitment to HIV services targeting PWID was highest among European countries (0.81) and lowest among African countries (0.50), with Oceania (0.76), Asia (0.66), and the Americas (0.56) in the mid-range. Subregional differences were even more prominent, with West and Central European nations (0.84) and Central American nations (0.22) earning the highest and lowest HPPI scores, respectively. CONCLUSIONS The HPPI documented substantial national and regional variation in policy responses to the HIV epidemic among PWID. Our analysis also revealed that many countries have limited HIV/AIDS data collection and monitoring capabilities. Continued enhancement and standardization of global HIV/AIDS monitoring efforts are therefore vital to articulated national and international benchmarking and performance assessment goals.

Abstract
This paper explores how a peer-and street-based naloxone distribution program (Bmore POWER) reshapes narratives and practices around drug use and harm reduction in an urban context with an enduring opioid epidemic. Data collection included observations of Bmore POWER outreach events and interviews with peers. Bmore POWER members create a sense of community responsibility around overdose prevention and reconfigure overdose hotspots from places of ambivalence to places of grassroots action. It expands a harm reduction approach to Black communities that have not traditionally embraced it and that have been underserved by drug treatment programs. Policy makers should consider ways to use peers grounded in specific communities to expand other aspects of harm reduction, such as syringe and support services.

Abstract
Background Needle-exchange programs (NEPs) reduce infections in people who inject drugs. This study assesses the impact community pharmacies have had in the Needle-Exchange Program in Portugal since 2015. Methods Health gains were measured by the number of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections averted, which were estimated, in each scenario, based on a standard model in the literature, calibrated to national data. The costs per infection were taken from national literature; costs of manufacturing, logistics and incineration of injection materials were also considered. The results were presented as net costs (i.e., incremental costs of the program with community pharmacies less the costs of additional infections avoided). Results Considering a 5-year horizon, the Needle Exchange Program with community pharmacies would account for a 6.8% (n = 25) and a 6.5% reduction (n = 22) of HCV and HIV infections, respectively. The present value of net savings generated by the participation of community pharmacies in the program was estimated at €2,073,347. The average discounted net benefit per syringe exchanged is €3.01, already taking into account a payment to community pharmacies per needle exchanged. Interpretation We estimate that the participation of community pharmacies in the Needle Exchange Program will lead to a reduction of HIV and HCV infections and will generate over €2 million in savings for the health system. Conclusions The intervention is estimated to generate better health outcomes at lower costs, contributing to improving the efficiency of the public health system in Portugal.

Abstract
BACKGROUND AND AIMS Australia is currently on track to meet the World Health Organization (WHO) global hepatitis C virus (HCV) elimination goals by 2030, reflecting universal subsidized access to testing and direct-acting antiviral (DAA) treatment. In New South Wales, DAA treatment in prisons has scaled-up substantially, with 1000 prisoners treated in 2017. However, HCV prevalence and incidence in this setting is high, which could undermine elimination efforts. This study aimed to test the preventative effects of DAA treatment scale-up, opiate substitution treatment (OST) and needle and syringe programme (NSP) strategies for prisons. DESIGN Modelling study using an individual-based mathematical model of a typical prison setting. The model was calibrated against Australian epidemiological data sets and executed in-prison events for each individual daily, including movements between prisons, changes in risk behaviour and uptake of prevention measures such as OST and NSP, as well as DAA treatment. Scenarios were projected from 2018 to 2030. SETTING New South Wales prisons. PARTICIPANTS New South Wales prisoners. MEASUREMENTS Variables including prison populations, prevalence and incidence rate were calculated. Prisoners were described by demographic characteristics, HCV infection history, risk behaviours and accessing treatment and prevention measures in varied security settings. FINDINGS Increasing the number of prisoners treated for HCV to 2000 annually was projected to reduce the HCV incidence rate to 8.69 [95% confidence interval (CI) = 8.17, 9.20] per 100 person-years (100 p.y.). Combined treatment and prevention strategies were necessary to reduce the projected incidence rate to 5.22 (95% CI = 5.13, 5.52) per 100 p.y. Considering the expected reductions in the prevalence of chronic HCV in the Australian community, incidence rate was predicted to drop to 0.93 (95% CI = 0.92, 0.98) per 100 p.y. by 2030. CONCLUSIONS This model, which simulates prison scenarios to inform Australia's national hepatitis C virus elimination efforts, suggests that continued direct-acting antiviral (coverage in the community combined with a moderate increase of direct-acting antiviral treatments in prisons, and introduction of improved harm reduction via opiate substitution treatment and/or needle and syringe programmes, makes hepatitis C virus elimination feasible in Australian prisons.

Abstract
OBJECTIVE To review key arguments supporting and criticizing syringe services programs (SSPs). DATA SOURCES Peer-reviewed literature and publicly available documents. SUMMARY Pharmacy organizations-including the American Pharmacists Association and the American Society of Health-System Pharmacists-have stated that pharmacists should support programs that supply sterile injection materials to persons who use injection drugs. SSPs may include needle exchanges or other programs that meet these aims. Pharmacists should know that observational public health research demonstrates that SSPs can lower the transmission of blood-borne illnesses, improve linkage to care for substance use disorders, reduce health care expenditures, and reduce drug overdoses. Concerns about SSPs and increases in syringe litter or crime have not been borne out by research. Despite these findings and the positions of professional organizations, contemporary research suggests that pharmacists may be reluctant to support SSPs and other programs that would increase supply of sterile injection supplies to their communities. CONCLUSION The review of evidence in this commentary should help pharmacists better understand the evidence in favor of SSPs, the potential criticisms of SSPs, and the reasons that their profession is moving to support these programs.

Abstract
Background and aims Using mathematical modeling to illustrate and predict how different heroin source-forms: “black tar” (BTH) and powder heroin (PH) can affect HIV transmission in the context of contrasting injecting practices. By quantifying HIV risk by these two heroin source-types we show how each affects the incidence and prevalence of HIV over time. From 1997 to 2010 PH reaching the United States was manufactured overwhelmingly by Colombian suppliers and distributed in the eastern states of the United States. Recently Mexican cartels that supply the western U.S. states have started to produce PH too, replacing Colombian distribution to the east. This raises the possibility that BTH in the western U.S. may be replaced by PH in the future. Design We used an agent-based model to evaluate the impact of use of different heroin formulations in high- and low-risk populations of persons who inject drugs (PWID) who use different types of syringes (high vs. low dead space) and injecting practices. We obtained model parameters from peer-reviewed publications and ethnographic research. Results Heating of BTH, additional syringe rinsing, and subcutaneous injection can substantially decrease the risk of HIV transmission. Simulation analysis shows that HIV transmission risk may be strongly affected by the type of heroin used. We reproduced historic differences in HIV prevalence and incidence. The protective effect of BTH is much stronger in high-risk compared with low-risk populations. Simulation of future outbreaks show that when PH replaces BTH we expect a long-term overall increase in HIV prevalence. In a population of PWID with mixed low- and high-risk clusters we find that local HIV outbreaks can occur even when the overall prevalence and incidence are low. The results are dependent on evidence-supported assumptions. Conclusions The results support harm-reduction measures focused on a reduction in syringe sharing and promoting protective measures of syringe rinsing and drug solution heating.

Abstract
DSM-V-defined substance use disorder comprises four groups of symptoms: impaired control, social impairment, risky use, and pharmacological reactions. Behavioral patterns of impaired control, including impulsivity and risk taking, are associated with HIV risk behaviors. Substance users with stronger craving symptoms are more likely to use drugs via intravenous injection than other routes because of the faster drug effect and the higher bioavailability; thus, they are at high risk of HIV infection. HIV risk behaviors such as unprotected sex and intravenous injection facilitate HIV disease spread. Public health policies such as Needle and Syringe Exchange Programs and medication-assisted treatment are proven to reduce HIV risk behaviors such as the frequency of intravenous injection and even the incidence of HIV infection, but both of them have limitations. While intravenous injection is a frequently discussed issue in public policies and the HIV-related literature, it is a much less frequent topic in the addiction literature. We believed that understanding the mental substrate behind impulsivity/risk taking and the possible biological mechanism of intravenous injection may help in creating more effective strategies to slow down HIV infection.

Longitudinal migration patterns from an open illicit drug scene among people who use illicit drugs in Vancouver, Canada. J Subst Abuse Treat 2019; 107:17-23. [PMID: 31757260 PMCID: PMC6892597 DOI: 10.1016/j.jsat.2019.09.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Revised: 09/23/2019] [Accepted: 09/27/2019] [Indexed: 12/16/2022]
Abstract
The objective of this study was to identify migration patterns from an open illicit drug scene (the Downtown Eastside [DTES] neighborhood) and describe factors associated with these migration patterns. Data were derived from three cohorts of people who use illicit drugs in Vancouver, Canada. Defined using latent class growth analysis, we identified four distinct migration trajectory groups: 1) consistently living in the DTES (47.8%); 2) early migration out, with a median time of migrating out of DTES of 5.3 months (21.5%); 3) late migration out, with a median time of migrating out of DTES of 38.0 months (20.1%); and 4) frequent revisit back-and-forth to DTES (10.6%). In a multivariable model, compared to the "consistently living in the DTES" group, factors associated with the "frequent revisit" group included being enrolled in non-pharmacological addiction treatment and having an HCV-positive serostatus. Factors associated with the "early migration out" group included being enrolled in detoxification or in other non-pharmacological addiction treatment, later calendar year, being on income assistance, living in a single room occupancy hotel, and having an HCV-positive serostatus. These findings point to the need for appropriate distribution of services in order to meet the needs of this population.

Abstract
Persons who inject drugs (PWID) continue to experience disproportionate HIV burden. Though studies demonstrate PWID find pre-exposure prophylaxis (PrEP) acceptable, awareness and uptake remains low. Data from the 2015 PWID cycle of the National HIV Behavioral Surveillance (n = 612) in Philadelphia, Pennsylvania (USA) were analyzed to evaluate how socio-demographics and behavioral factors impact PrEP awareness. Only 12.4% of PWID surveyed were PrEP-aware and 2.6% reported receiving a prescription. Factors associated with PrEP awareness included having at least some college education (aOR 2.13, 95% CI 1.03, 4.43), sharing paraphernalia (aOR 2.37, 95% CI 1.23, 4.56), obtaining syringes/needles primarily from a syringe exchange program (aOR 2.28, 95% CI 1.35, 3.87), STI testing (aOR 1.71, 95% CI 1.01, 2.89) and drug treatment (aOR 2.81, 95% CI 1.62, 4.87). Accessing prevention and health services increased the odds of being PrEP-aware; however, awareness was low overall. Additional promotion efforts are warranted.

Abstract
PURPOSE OF REVIEW Syringe access programs (SAPs) are cornerstone harm reduction interventions for combatting the national opioid epidemic. The goal of this paper is to describe effective advocacy strategies for enacting syringe decriminalization legislation to foster the expansion of SAPs in high-need areas amidst political opposition. RECENT FINDINGS Decades or research shows that SAPs prevent the transmission of HIV among people who inject drugs (PWID) and are a cost-effective tool for linking PWID to medical care, health education, and social services. In the USA, state laws criminalizing distribution and possession of syringes impede the expansion of SAPs into areas where they are sorely needed. In 2016, North Carolina became the first state to legalize SAPs with a Republican super majority. This paper distills strategies for community organizations seeking to advance syringe decriminalization legislation in politically conservative states with histories of prioritizing punitive sanctions over public health responses to drug use.

Abstract
BACKGROUND Many studies have found significant differences in HIV risk at the community and socioeconomic levels. However, few have considered variations in needle and syringe program (Jin et al., Oral Dis. 1;22(7):609-19) coverage and other community characteristics on HIV risk behaviors among people who inject drugs (PWIDs). Our objective was to study the relationship between individual factors and city-level characteristics (such as the city's coverage of harm reduction programs) on HIV risk behavior among PWID residing in two cities in Iran. METHODS The study was conducted from March to August 2016 in Tehran and Kermanshah provinces. One thousand PWID were recruited by a convenience sampling recruitment at local NSP Drop-in Centers (DIC) and through "snowball sampling" (i.e., using peers to refer participants to the study). We first examined associations between individual-level variables and HIV risk behaviors in bivariate analysis using the chi-square or Fisher's exact tests, as appropriate. Next, multi-level models were constructed to determine the amount of variability in HIV risk behavior that could be accounted for by individual- and community-level characteristics. Variables with p value < 0.2 were included in the multiple logistic regression model. RESULTS The results of the multilevel modeling showed that 32% of the variability in HIV risk behaviors among PWID could be explained by factors that differed between the two cities. When individual factors including higher HIV knowledge, access to NSP, higher HIV risk perception, and methamphetamine use were all included in the final model, 22% of the variability in HIV risk behaviors could be explained to city-level variables. CONCLUSION Findings suggest that expanding the accessibility (i.e., hours and venues) and community-level coverage of NSP services by establishing programs where PWID congregate might reduce HIV risk behavior among PWID.

Abstract
Adults presenting with substance use and mental health disorders in the criminal justice system is well documented. While studies have examined drug courts and medication-assisted treatment (MAT), few have examined social and behavioral health indicators, and even fewer have multiple study periods. This study employed a comprehensive approach to studying the MAT contribution to drug court success; reduce substance use, mental health symptoms, and risky behaviors; and the role that violence or trauma plays in mental health symptomatology. Using three time points, our findings indicated that MAT did not play a significant role in the reduction of substance use, risky behaviors, or mental health symptoms or increasing the odds of successful court graduation. However, there was an overall improvement from intake to termination in reduction of substance use, risky behaviors, and mental health symptomatology. Other factors, including social support, may play a role in drug court graduation. Policy implications are discussed.

Abstract
BACKGROUND Limited research has examined pre-exposure prophylaxis (PrEP) interest among people who inject drugs (PWID). To date, few studies have examined the relationship between PrEP eligibility and PrEP interest among PWID. METHODS Data were from an anonymous, cross-sectional survey of Baltimore Syringe Services Program (SSP) clients and non-client peers, restricted to HIV-uninfected participants (N = 265). Participants were classified as PrEP eligible/ineligible based on injection related criteria outlined in the CDC's PrEP guidelines. Participants were asked if they were previously aware of PrEP, would be interested in taking PrEP, and the ease of taking PrEP daily. Participants self-reported their sociodemographic characteristics, health diagnoses, and recent drug use, overdose, and drug treatment history. We estimated bivariate and multivariate logistic regression models to test for significant predictors of interest in PrEP. RESULTS One-quarter of PWID had previously heard of PrEP and 63% of the sample was interested in taking PrEP. Only two respondents were currently taking PrEP. The majority (89%) thought taking PrEP every day would be easy. In the presence of other variables, PrEP interest was associated with PrEP eligibility (adjusted odds ratio [aOR] = 2.46; 95% Confidence Interval [CI]:1.34,4.50) and the number of medical diagnoses (aOR = 1.16; 95% CI:1.01,1.33) CONCLUSIONS: Most PWID were unaware of PrEP but interested in taking it. PWID who were eligible for PrEP are more likely to be interested in taking it. Having co-morbid conditions was an important correlate of PrEP interest. These results underscore the importance of providers across the healthcare sector engaging PWID in discussions about PrEP.

Abstract
The world prison population is growing at a rate that exceeds the rate of population growth. This issue of Epidemiologic Reviews comprises articles in which researchers summarize what is known about some of the key health issues facing people in prison, particularly in relation to human immunodeficiency virus and other blood-borne viral infections. A key recurring theme is that addressing the health needs of people in prison is important to reducing health inequalities at the population level—that prisoner health is public health. The reviews also highlight some critical evidence gaps, notably the lack of evidence from low- and middle-income countries, and the limited number of longitudinal studies in which health behaviors, health outcomes, or health service experiences after release from prison are documented. Despite growing evidence of the poor health of detained adolescents, none of the included reviews considered this population. Further research on the health of young people who cycle through juvenile detention should be a priority. Despite a rapidly growing literature on the health of people who experience incarceration, some critical health issues remain poorly understood, and there has been insufficient attention devoted to co-occurring health conditions and the consequent need for coordinated care. Key populations in custodial settings remain understudied, limiting capacity to develop targeted, evidence-based responses to their health needs. The quality of many studies is suboptimal, and although rigorous, independent research in correctional settings can be challenging, it is not impossible and is critical to laying the groundwork for evidence-based reform.

Abstract
We assessed the association between different levels of needle exchange program (NEP) use and human immunodeficiency virus (HIV) seroconversion in the injecting drug user (IDU) population using meta-analysis to aggregate risk estimates from any reported cohort studies or randomized controlled trials (RCTs) in the literature. We searched the literature for articles published from January 1990 to August 2014 using Medical Subject Headings and other terms from MEDLINE® (using Ovid), Embase, ProQuest, the International Aids Society Abstract database, and the European AIDS clinical society database, and the European Conferences Abstract Archive. Articles were included if data were reported from an original study; the study was a prospective cohort or RCT design; estimates for seroconversion (hazard ratios [HRs]) for drug-users with different levels of NEP-use, as well as variance data, or the information to calculate these were reported; risk estimates were adjusted for unstable housing, risky sexual behaviors, frequency of injections, cocaine use, and risky needle sharing practices; and the study was published between January 1990 and August 2014. Information abstracted was general study information (i.e., study name, authors, publication year, study site, sample size, length of follow-up, and follow-up intervals, incentives to IDUs for improving compliance/enrollment), outcomes variable measures (seroconversion HR estimates, variance figures, and factors adjusted for), description of the study population (inclusion and exclusion criteria and definitions of comparison groups), type of intervention (NEP program), statistical methods used, and sub-group information. Two prospective cohort studies with a total of 3,172 IDUs were eligible for inclusion. Comparison groups had different levels of NEP-use (e.g., daily use vs. non-daily use and NEP-users vs. non-users) from fixed-site NEPs. Our Q-statistic was insignificant with a p-value of 0.401 while the I2 value was 0.0%. A random-effects model was used to aggregate the estimates, and we found an overall significant positive association between NEP-use and HIV seroconversion with an HR estimate of 1.59 (95% confidence interval [CI]: 1.2 to 2.1). According to our results, higher usage of NEPs is associated with a higher risk of HIV seroconversion in the IDU population. The observed association aligns with previous findings of NEP programs being inadequate for HIV control in IDUs. Further research on the topic needs to be done including studies on different NEP designs and how they can be made more effective by combining with other strategies, including the study of IDU characteristics which make them more likely to use safe syringes when they inject.

Abstract
AIMS To estimate the effects of needle and syringe programmes (NSP) and opioid substitution therapy (OST), alone or in combination, for preventing acquisition of hepatitis C virus (HCV) in people who inject drugs (PWID). METHODS Systematic review and meta-analysis. Bibliographic databases were searched for studies measuring concurrent exposure to current OST (within the last 6 months) and/or NSP and HCV incidence among PWID. High NSP coverage was defined as regular NSP attendance or ≥ 100% coverage (receiving sufficient or greater number of needles and syringes per reported injecting frequency). Studies were assessed using the Cochrane risk of bias in non-randomized studies tool. Random-effects models were used in meta-analysis. RESULTS We identified 28 studies (n = 6279) in North America (13), United Kingdom (five), Europe (four), Australia (five) and China (one). Studies were at moderate (two), serious (17) critical (seven) and non-assessable risk of bias (two). Current OST is associated with 50% [risk ratio (RR) =0.50, 95% confidence interval (CI) = 0.40-0.63] reduction in HCV acquisition risk, consistent across region and with low heterogeneity (I2 = 0, P = 0.889). Weaker evidence was found for high NSP coverage (RR = 0.79, 95% CI = 0.39-1.61) with high heterogeneity (I2 = 77%, P = 0.002). After stratifying by region, high NSP coverage in Europe was associated with a 56% reduction in HCV acquisition risk (RR = 0.44, 95% CI = 0.24-0.80) with low heterogeneity (I2 = 12.3%, P = 0.337), but not in North America (RR = 1.58, I2 = 89.5%, P = < 0.001). Combined OST/NSP is associated with a 74% reduction in HCV acquisition risk (RR = 0.26, 95% CI = 0.07-0.89, I2 = 80% P = 0.007). According to Grades of Recommendation Assessment, Development and Evaluation (GRADE) criteria, the evidence on OST and combined OST/NSP is low quality, while NSP is very low. CONCLUSIONS Opioid substitution therapy reduces risk of hepatitis C acquisition and is strengthened in combination with needle and syringe programmes (NSP). There is weaker evidence for the impact of needle syringe programmes alone, although stronger evidence that high coverage is associated with reduced risk in Europe.

Abstract
BACKGROUND Although much research has been conducted on the determinants of HIV risk behavior among people who inject drugs (PWID), the influence of the neighborhood context on high-risk injection behavior remains understudied. To address this gap in the literature, we measured associations between neighborhood socioeconomic disadvantage and high-risk injection behavior, and determined whether these associations were modified by drug-related police activity and syringe exchange program (SEP) accessibility. METHODS Our sample was comprised of 484 pharmacy-recruited PWID in New York City. Measures of neighborhood socioeconomic disadvantage were created using data from the 2006-2010 American Community Survey. Associations with high-risk injection behavior were estimated using multivariable Poisson regression. Effect modification by drug-related police activity and SEP accessibility was assessed by entering cross-product terms into adjusted models of high-risk injection behavior. RESULTS Neighborhood socioeconomic disadvantage was associated with decreased receptive syringe sharing and unsterile syringe use. In neighborhoods with high drug-related police activity, associations between neighborhood disadvantage and unsterile syringe use were attenuated to the null. In neighborhoods with high SEP accessibility, neighborhood disadvantage was associated with decreased acquisition of syringes from an unsafe source. CONCLUSIONS PWID in disadvantaged neighborhoods reported safer injection behaviors than their counterparts in neighborhoods that were relatively better off. The contrasting patterns of effect modification by SEP accessibility and drug-related police activity support the use of harm reduction approaches over law enforcement-based strategies for the control of blood borne virus transmission among PWID in disadvantaged urban areas.

Abstract
BACKGROUND Needle syringe programmes and opioid substitution therapy for preventing hepatitis C transmission in people who inject drugsNeedle syringe programmes (NSP) and opioid substitution therapy (OST) are the primary interventions to reduce hepatitis C (HCV) transmission in people who inject drugs. There is good evidence for the effectiveness of NSP and OST in reducing injecting risk behaviour and increasing evidence for the effectiveness of OST and NSP in reducing HIV acquisition risk, but the evidence on the effectiveness of NSP and OST for preventing HCV acquisition is weak. OBJECTIVES To assess the effects of needle syringe programmes and opioid substitution therapy, alone or in combination, for preventing acquisition of HCV in people who inject drugs. SEARCH METHODS We searched the Cochrane Drug and Alcohol Register, CENTRAL, the Cochrane Database of Systematic Reviews (CDSR), the Database of Abstracts of Reviews of Effects (DARE), the Health Technology Assessment Database (HTA), the NHS Economic Evaluation Database (NHSEED), MEDLINE, Embase, PsycINFO, Global Health, CINAHL, and the Web of Science up to 16 November 2015. We updated this search in March 2017, but we have not incorporated these results into the review yet. Where observational studies did not report any outcome measure, we asked authors to provide unpublished data. We searched publications of key international agencies and conference abstracts. We reviewed reference lists of all included articles and topic-related systematic reviews for eligible papers. SELECTION CRITERIA We included prospective and retrospective cohort studies, cross-sectional surveys, case-control studies and randomised controlled trials that measured exposure to NSP and/or OST against no intervention or a reduced exposure and reported HCV incidence as an outcome in people who inject drugs. We defined interventions as current OST (within previous 6 months), lifetime use of OST and high NSP coverage (regular attendance at an NSP or all injections covered by a new needle/syringe) or low NSP coverage (irregular attendance at an NSP or less than 100% of injections covered by a new needle/syringe) compared with no intervention or reduced exposure. DATA COLLECTION AND ANALYSIS We followed the standard Cochrane methodological procedures incorporating new methods for classifying risk of bias for observational studies. We described study methods against the following 'Risk of bias' domains: confounding, selection bias, measurement of interventions, departures from intervention, missing data, measurement of outcomes, selection of reported results; and we assigned a judgment (low, moderate, serious, critical, unclear) for each criterion. MAIN RESULTS We identified 28 studies (21 published, 7 unpublished): 13 from North America, 5 from the UK, 4 from continental Europe, 5 from Australia and 1 from China, comprising 1817 incident HCV infections and 8806.95 person-years of follow-up. HCV incidence ranged from 0.09 cases to 42 cases per 100 person-years across the studies. We judged only two studies to be at moderate overall risk of bias, while 17 were at serious risk and 7 were at critical risk; for two unpublished datasets there was insufficient information to assess bias. As none of the intervention effects were generated from RCT evidence, we typically categorised quality as low. We found evidence that current OST reduces the risk of HCV acquisition by 50% (risk ratio (RR) 0.50, 95% confidence interval (CI) 0.40 to 0.63, I2 = 0%, 12 studies across all regions, N = 6361), but the quality of the evidence was low. The intervention effect remained significant in sensitivity analyses that excluded unpublished datasets and papers judged to be at critical risk of bias. We found evidence of differential impact by proportion of female participants in the sample, but not geographical region of study, the main drug used, or history of homelessness or imprisonment among study samples.Overall, we found very low-quality evidence that high NSP coverage did not reduce risk of HCV acquisition (RR 0.79, 95% CI 0.39 to 1.61) with high heterogeneity (I2 = 77%) based on five studies from North America and Europe involving 3530 participants. After stratification by region, high NSP coverage in Europe was associated with a 76% reduction in HCV acquisition risk (RR 0.24, 95% CI 0.09 to 0.62) with less heterogeneity (I2 =0%). We found low-quality evidence of the impact of combined high coverage of NSP and OST, from three studies involving 3241 participants, resulting in a 74% reduction in the risk of HCV acquisition (RR 0.26 95% CI 0.07 to 0.89). AUTHORS' CONCLUSIONS OST is associated with a reduction in the risk of HCV acquisition, which is strengthened in studies that assess the combination of OST and NSP. There was greater heterogeneity between studies and weaker evidence for the impact of NSP on HCV acquisition. High NSP coverage was associated with a reduction in the risk of HCV acquisition in studies in Europe.

Assessing the impact and cost-effectiveness of needle and syringe provision and opioid substitution therapy on hepatitis C transmission among people who inject drugs in the UK: an analysis of pooled data sets and economic modelling.

Abstract
Background
There is limited evidence of the impact of needle and syringe programmes (NSPs) and opioid substitution therapy (OST) on hepatitis C virus (HCV) incidence among people who inject drugs (PWID), nor have there been any economic evaluations.
Objective(s)
To measure (1) the impact of NSP and OST, (2) changes in the extent of provision of both interventions, and (3) costs and cost-effectiveness of NSPs on HCV infection transmission.
Design
We conducted (1) a systematic review; (2) an analysis of existing data sets, including collating costs of NSPs; and (3) a dynamic deterministic model to estimate the impact of differing OST/NSP intervention coverage levels for reducing HCV infection prevalence, incidence and disease burden, and incremental cost-effectiveness ratios to measure the cost-effectiveness of current NSP provision versus no provision.
Setting
Cost-effectiveness analysis and impact modelling in three UK sites. The pooled analysis drew on data from the UK and Australia. The review was international.
Participants
PWID.
Interventions
NSP coverage (proportion of injections covered by clean needles) and OST.
Outcome
New cases of HCV infection.
Results
The review suggested that OST reduced the risk of HCV infection acquisition by 50% [rate ratio (RR) 0.50, 95% confidence interval (CI) 0.40 to 0.63]. Weaker evidence was found in areas of high (≥ 100%) NSP coverage (RR 0.77, 95% CI 0.38 to 1.54) internationally. There was moderate evidence for combined high coverage of NSPs and OST (RR 0.29, 95% CI 0.13 to 0.65). The pooled analysis showed that combined high coverage of NSPs and OST reduced the risk of HCV infection acquisition by 29–71% compared with those on minimal harm reduction (no OST, ≤ 100% NSP coverage). NSPs are likely to be cost-effective and are cost-saving in some settings. The impact modelling suggest that removing OST (current coverage 81%) and NSPs (coverage 54%) in one site would increase HCV infection incidence by 329% [95% credible interval (CrI) 110% to 953%] in 2031 and at least double (132% increase; 95% CrI 51% to 306%) the number of new infections over 15 years. Increasing NSP coverage to 80% has the largest impact in the site with the lowest current NSP coverage (35%), resulting in a 27% (95% CrI 7% to 43%) decrease in new infections and 41% (95% CrI 11% to 72%) decrease in incidence by 2031 compared with 2016. Addressing homelessness and reducing the harm associated with the injection of crack cocaine could avert approximately 60% of HCV infections over the next 15 years.
Limitations
Findings are limited by the misclassification of NSP coverage and the simplified intervention definition that fails to capture the integrated services that address other social and health needs as part of this.
Conclusions
There is moderate evidence of the effectiveness of OST and NSPs, especially in combination, on HCV infection acquisition risk. Policies to ensure that NSPs can be accessed alongside OST are needed. NSPs are cost-saving in some sites and cost-effective in others. NSPs and OST are likely to prevent considerable rates of HCV infection in the UK. Increasing NSP coverage will have most impact in settings with low coverage. Scaling up other interventions such as HCV infection treatment are needed to decrease epidemics to low levels in higher prevalence settings.
Future work
To understand the mechanisms through which NSPs and OST achieve their effect and the optimum contexts to support implementation.

Abstract
Inadequate response to injecting drug use (IDU) is a significant problem the world over. Low levels of funding, political inaction, poor levels of health service coverage, high prevalence and incidence of IDU-related blood-borne viruses (BBVs) and ongoing stigmatization/marginalization affect people who inject drugs (PWID) regardless of the income status of the country they reside in. These barriers and system failings are, however, exacerbated in low and middle-income countries (LMICs), meaning that the potential consequences of inaction are more pressing. In this narrative review, we describe the levels of IDU and IDU-specific BBV prevalence in LMICs; levels of harm reduction implementation; the consequences of late or insufficient response, the shortcomings of data collection and dissemination; and the barriers to effective LMIC harm reduction implementation. We also exemplify cases where IDU-related harms and BBV epidemics have been successfully curtailed in LMICs, showing that effective response, despite the barriers, is possible. In conclusion, we suggest four key priorities on the basis of the review: confirming the presence or absence of IDU in LMICs, improving the collection and dissemination of national IDU-specific data, increasing the level of harm reduction programme implementation in LMICs, and increasing both national and international advocacy for PWID and attendant public health interventions.

Abstract
BACKGROUND While there is substantial evidence that syringe exchange programs (SEPs) are effective in preventing HIV among people who inject drugs (PWID), nearly all the evidence comes from PWID who obtain syringes from an SEP directly. Much less is known about the benefits of secondary exchange to PWID who get syringes indirectly from friends or acquaintances who visit an SEP for them. OBJECTIVES We evaluated the effectiveness of direct versus indirect syringe exchange in reducing HIV-related high-risk injecting behavior among PWID in two separate studies conducted in Sacramento and San Jose, California, cities with quite different syringe exchange models. METHODS In both studies associations between direct and indirect syringe exchange and self-reported risk behavior were examined with multivariable logistic regression models. Study 1 assessed effects of a "satellite" home-delivery syringe exchange in Sacramento, while Study 2 evaluated a conventional fixed-site exchange in San Jose. RESULTS Multivariable analyses revealed 95% and 69% reductions, respectively, in high-risk injection associated with direct use of the SEPs in Sacramento and San Jose, and a 46% reduction associated with indirect use of the SEP in Sacramento. Conclusions/Importance: The very large effect of direct SEP use in Sacramento was likely due in part to home delivery of sterile syringes. While more modest effects were associated with indirect use, such use nevertheless is valuable in reducing the risk of HIV transmission of PWID who are unable or unwilling to visit a syringe exchange.

Abstract
Many important and rapidly emerging pathogens of humans, livestock and wildlife are 'vector-borne'. However, the term 'vector' has been applied to diverse agents in a broad range of epidemiological systems. In this perspective, we briefly review some common definitions, identify the strengths and weaknesses of each and consider the functional differences between vectors and other hosts from a range of ecological, evolutionary and public health perspectives. We then consider how the use of designations can afford insights into our understanding of epidemiological and evolutionary processes that are not otherwise apparent. We conclude that from a medical and veterinary perspective, a combination of the 'haematophagous arthropod' and 'mobility' definitions is most useful because it offers important insights into contact structure and control and emphasizes the opportunities for pathogen shifts among taxonomically similar species with similar feeding modes and internal environments. From a population dynamics and evolutionary perspective, we suggest that a combination of the 'micropredator' and 'sequential' definition is most appropriate because it captures the key aspects of transmission biology and fitness consequences for the pathogen and vector itself. However, we explicitly recognize that the value of a definition always depends on the research question under study.This article is part of the themed issue 'Opening the black box: re-examining the ecology and evolution of parasite transmission'.

Abstract
BACKGROUND Injection drug use and its associated blood-borne infections has become a rapidly increasing problem in rural areas of the US recently. Syringe exchange programs have been shown to be effective for reducing transmission of blood borne infections, however access to these prevention efforts may be limited in rural areas. METHODS This paper utilizes two separate community samples of people who inject drugs (PWID) in Puerto Rico to achieve the following research objectives: (1) compare rural and urban access to syringe exchange programs, free sterile syringes and other HIV/HCV prevention activities, and (2) examine whether utilization of prevention activities is associated with lower injection risk behaviors. Two samples were recruited with RDS (n=315 rural sample; n=512 urban sample) and included adults aged 18 years and older who have injected drugs within the past month. RESULTS 78.5% of the urban sample utilized a syringe exchange program in the past year, compared to 58.4% of the rural sample (p<.001). 71.4% of the urban sample received free sterile needles, compared to 58.4% of the rural sample (p<.001). 66% of the urban sample received free works compared to 59% of the rural sample (p=.034). 29% of urban PWID had a conversation with an outreach worker about HIV prevention compared to 18% of the rural sample (p<0.001). Receiving free needles significantly increases the frequency of using a sterile needle to inject (p<.001). CONCLUSION Urban PWID were significantly more likely to have utilized syringe exchange programs, received free sterile needles, received free works, and to have talked about HIV prevention with an outreach worker during the past year than PWID residing in rural areas. Individuals who accessed these prevention activities were significantly less likely to exhibit risky injection behavior. Policy implications call for increasing access to prevention services in rural areas to reduce disease transmission.

Abstract
BACKGROUND Needle and syringe programmes (NSP) are a critical component of harm reduction interventions among people who inject drugs (PWID). Our primary objective was to summarize the evidence on the effectiveness of NSP for PWID in reducing blood-borne infection transmission and injecting risk behaviours (IRB). METHODS We conducted an overview of systematic reviews that included PWID (excluding prisons and consumption rooms), addressed community-based NSP, and provided estimates of the effect regarding incidence/prevalence of Human Immunodeficiency Virus (HIV), Hepatitis C virus (HCV), Hepatitis B virus (HBV) and bacteremia/sepsis, and/or measures of IRB. Systematic literature searches were undertaken on relevant databases, including EMBASE, MEDLINE, and PsychINFO (up to May 2015). For each review we identified relevant studies and extracted data on methods, and findings, including risk of bias and quality of evidence assessed by review authors. We evaluated the risk of bias of each systematic review using the ROBIS tool. We categorized reviews by reported outcomes and use of meta-analysis; no additional statistical analysis was performed. RESULTS We included thirteen systematic reviews with 133 relevant unique studies published between 1989 and 2012. Reported outcomes related to HIV (n = 9), HCV (n = 8) and IRB (n = 6). Methods used varied at all levels of design and conduct, with four reviews performing meta-analysis. Only two reviews were considered to have low risk of bias using the ROBIS tool, and most included studies were evaluated as having low methodological quality by review authors. We found that NSP was effective in reducing HIV transmission and IRB among PWID, while there were mixed results regarding a reduction of HCV infection. Full harm reduction interventions provided at structural level and in multi-component programmes, as well as high level of coverage, were more beneficial. CONCLUSIONS The heterogeneity and the overall low quality of evidence highlights the need for future community-level studies of adequate design to support these results. TRIAL REGISTRATION The protocol of this systematic review was registered in Prospective Register of Systematic Reviews (PROSPERO 2015: CRD42015026145 ).

Abstract
The burden of substance use and especially the unmatched rates of overdoses in rural Central Appalachia highlight the need for innovative approaches to curb the initiation to drug misuse and to address current substance use disorders. Effective substance use interventions involve a thorough understanding of the region. In Central Appalachia, many of the barriers to treatment are shared with other rural and impoverished areas, including a lack of access to health care and lack of health care providers with specialized training. Parts of Appalachia also present their own considerations, including the challenges of fostering trust and encouraging treatment-seeking in communities with dense, long-term, place-based social and family networks. Current policies and interventions for substance use have been largely inadequate in the region, as evidenced by continued increases in substance use and substance-related deaths, especially related to nonmedical prescription drug use and increasing heroin use. The authors discuss ways in which rural life, poverty, identity, and values in Appalachia have influenced substance use and treatment and propose strategies and interventions to improve outcomes.

Abstract
Health care budgets and policies are chief drivers in the delivery and access to health services. Place is also a factor that affects patient and provider experiences within the health care system. We examine the impact of policy changes and subsequent budget cuts on rural HIV/AIDS care, support services, and prevention. We interviewed 11 social workers, case managers, and outreach workers who serve rural people living with HIV/AIDS. We conducted telephone interviews inquiring about the effect of economics and policies on direct practice with rural clients. We analyzed data using a content analysis approach. We found several themes from the data. Ryan White funding and policy changes shifted direct practice to a medical case management model. Changes in federal and state poverty levels affected client eligibility for the AIDS Drugs Assistance Program. Policy banning financial support for syringe service programs hindered prevention efforts to reduce HIV/AIDS transmission. Ancillary services were reduced, such as housing assistance, transportation, and emergency financial assistance. In conclusion, we highlight the importance of place-based policies to improve access to healthcare and services. We also provide recommendations for greater inclusion in HIV/AIDS-related policy development, care, and service planning for rural workers.

High variability of HIV and HCV seroprevalence and risk behaviours among people who inject drugs: results from a cross-sectional study using respondent-driven sampling in eight German cities (2011-14). BMC Public Health 2016; 16:927. [PMID: 27595567 PMCID: PMC5011883 DOI: 10.1186/s12889-016-3545-4] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2016] [Accepted: 08/18/2016] [Indexed: 12/15/2022] Open
Abstract
Background People who inject drugs (PWID) are at increased risk of acquiring and transmitting HIV and Hepatitis C (HCV) due to sharing injection paraphernalia and unprotected sex. To generate seroprevalence data on HIV and HCV among PWID and related data on risk behaviour, a multicentre sero- and behavioural survey using respondent driven sampling (RDS) was conducted in eight German cities between 2011 and 2014. We also evaluated the feasibility and effectiveness of RDS for recruiting PWID in the study cities. Methods Eligible for participation were people who had injected drugs within the last 12 months, were 16 years or older, and who consumed in one of the study cities. Participants were recruited, using low-threshold drop-in facilities as study sites. Initial seeds were selected to represent various sub-groups of people who inject drugs (PWID). Participants completed a face-to-face interview with a structured questionnaire about socio-demographics, sexual and injecting risk behaviours, as well as the utilisation of health services. Capillary blood samples were collected as dried blood spots and were anonymously tested for serological and molecular markers of HIV and HCV. The results are shown as range of proportions (min. and max. values (%)) in the respective study cities. For evaluation of the sampling method we applied criteria from the STROBE guidelines. Results Overall, 2,077 PWID were recruited. The range of age medians was 29–41 years, 18.5–35.3 % of participants were female, and 9.2–30.6 % were foreign born. Median time span since first injection were 10–18 years. Injecting during the last 30 days was reported by 76.0–88.4 % of participants. Sharing needle/syringes (last 30 days) ranged between 4.7 and 22.3 %, while sharing unsterile paraphernalia (spoon, filter, water, last 30 days) was reported by 33.0–43.8 %. A majority of participants (72.8–85.8 %) reported incarceration at least once, and 17.8–39.8 % had injected while incarcerated. Between 30.8 and 66.2 % were currently in opioid substitution therapy. Unweighted HIV seroprevalence ranged from 0–9.1 %, HCV from 42.3–75.0 %, and HCV-RNA from 23.1–54.0 %. The implementation of RDS as a recruiting method in cooperation with low-threshold drop in facilities was well accepted by both staff and PWID. We reached our targeted sample size in seven of eight cities. Conclusions In the recruited sample of mostly current injectors with a long duration of injecting drug use, seroprevalence for HIV and HCV varied greatly between the city samples. HCV was endemic among participants in all city samples. Our results demonstrate the necessity of intensified prevention strategies for blood-borne infections among PWID in Germany.

Abstract
PURPOSE Investigate whether characteristics of geographic areas are associated with condomless sex and injection-related risk behavior among racial/ethnic groups of people who inject drugs (PWID) in the United States. METHODS PWID were recruited from 19 metropolitan statistical areas for 2009 National HIV Behavioral Surveillance. Administrative data described ZIP codes, counties, and metropolitan statistical areas where PWID lived. Multilevel models, stratified by racial/ethnic groups, were used to assess relationships of place-based characteristics to condomless sex and injection-related risk behavior (sharing injection equipment). RESULTS Among black PWID, living in the South (vs. Northeast) was associated with injection-related risk behavior (adjusted odds ratio [AOR] = 2.24, 95% confidence interval [CI] = 1.21-4.17; P = .011), and living in counties with higher percentages of unaffordable rental housing was associated with condomless sex (AOR = 1.02, 95% CI = 1.00-1.04; P = .046). Among white PWID, living in ZIP codes with greater access to drug treatment was negatively associated with condomless sex (AOR = 0.93, 95% CI = 0.88-1.00; P = .038). CONCLUSIONS Policies that increase access to affordable housing and drug treatment may make environments more conducive to safe sexual behaviors among black and white PWID. Future research designed to longitudinally explore the association between residence in the south and injection-related risk behavior might identify specific place-based features that sustain patterns of injection-related risk behavior.

Abstract
Efforts to prevent the spread of HIV and hepatitis among injection drug users (IDUs) by improving access to sterile syringes can raise questions about syringe disposal. This study sought to evaluate the acceptability and utility of the Voyager, a newly approved, hand-held syringe disposal device for active injection drug users (IDUs). We offered the Voyager to active IDUs (n = 97), and interviewed them upon receiving the device and one month later. Almost all (90%) accepted the device. At follow-up, 78% had used the Voyager and 44% reported using it all the time; 65% reported they would like to continue using the Voyager and 77% rated the device “somewhat better” or “much better” than other methods of syringe disposal. Many IDUs care about safe syringe disposal and are willing and able to use a convenient disposal device such as the Voyager. Communities concerned about needlestick injuries and re-use of contaminated syringes should explore increasing the availability of such a device for IDUs as part of an overall approach to prevent improperly discarded syringes.

Abstract
Although many studies have found an association between harm reduction interventions and reductions in incidence rates of Human Immunodeficiency Virus (HIV) infection, scant research explores the effects of harm reduction cross-nationally. This study used a year- and country-level fixed effects model to estimate the potential effects of needle-and-syringe programs (NSPs) and methadone maintenance therapy (MMT) on incidence rates of HIV in the general population and among people who inject drugs (PWID), in a sample of 28 European nations. After adjusting for Gross Domestic Product (GDP) and total expenditures on healthcare, we identified significant associations between years of MMT and NSP implementation and lower incidence rates of HIV among PWID and the general population. In addition to years of implementation of NSP and MMT, the greater proportion of GDP spent on healthcare was associated with a decrease in logged incidence rates of HIV. The findings of this study suggest that MMT and NSP may reduce incidence rates of HIV among PWID cross-nationally. The current study opens a new avenue of exploration, which allows for a focus on countrywide policies and economic drivers of the epidemic. Moreover, it highlights the immense importance of the adoption of harm reduction programs as empirically-based health policy as well as the direct benefits that are accrued from public spending on healthcare on incidence rates of HIV within the general population and among subpopulations of PWID.

Abstract
INTRODUCTION AND AIMS Syringe distribution policies continue to be debated in many jurisdictions throughout the USA. The Baltimore Needle and Syringe Exchange Program (NSP) operated under a 1-for-1 syringe exchange policy from its inception in 1994 through 1999, when it implemented a restrictive policy (2000-2004) that dictated less than 1-for-1 exchange for non-program syringes. DESIGN AND METHODS Data were derived from the Baltimore NSP, which prospectively collected data on all client visits. We examined the impact of this restrictive policy on program-level output measures (i.e. distributed : returned syringe ratio, client volume) before, during and after the restrictive exchange policy. Through multiple logistic regression, we examined correlates of less than 1-for-1 exchange ratios at the client level before and during the restrictive exchange policy periods. RESULTS During the restrictive policy period, the average annual program-level ratio of total syringes distributed : returned dropped from 0.99 to 0.88, with a low point of 0.85 in 2000. There were substantial decreases in the average number of syringes distributed, syringes returned, the total number of clients and new clients enrolling during the restrictive compared to the preceding period. During the restrictive period, 33 508 more syringes were returned to the needle exchange than were distributed. In the presence of other variables, correlates of less than 1-for-1 exchange ratio were being white, female and less than 30 years old. DISCUSSION AND CONCLUSIONS With fewer clean syringes in circulation, restrictive policies could increase the risk of exposure to HIV among Injection Drug Users (IDUs) and the broader community. The study provides evidence to the potentially harmful effects of such policies.

Abstract
In 1981, when acquired immune deficiency syndrome (AIDS) was first observed among persons who inject drugs, almost all US states had laws criminalizing the possession and distribution of needles and syringes for injecting illicit drugs. We reviewed changes to these laws to permit 'syringe exchanges' and the provision of public funding for such programs. Most of the changes in law occurred during the 1990s, 5-10 years later than in many other countries. Public funding of syringe exchanges is associated with lower rates of human immunodeficiency virus (HIV) infection, greater numbers of syringes distributed (a possible causal mechanism), and greater numbers of health and social services provided. Experience in the United states may prove useful in other countries: state, provincial, and local governments may need to move ahead of central governments in addressing HIV infection among persons who inject drugs.
