Syringe Access, Syringe Sharing, and Perceptions of HCV: A Qualitative Study Exploring the HCV Risk Environment in Rural Northern New England, United States. Viruses 2024; 16:1364.

Abstract
The ongoing hepatitis C virus (HCV) epidemic in the United States disproportionately affects rural people who inject drugs (PWID). This study explores the HCV risk environment in rural northern New England by examining PWID experiences and perceptions of HCV and injection equipment-sharing practices. We performed a thematic analysis on semi-structured interviews conducted with 21 adults with a history of injection drug use from rural New Hampshire, Vermont, and Massachusetts between April 2018 and August 2019. Salient themes included: (1) limited and varied access to sterile syringe sources; (2) syringe scarcity contributing to the use of informal syringe sources (e.g., secondary syringe exchange or syringe sellers who purchased syringes from out-of-state pharmacies); (3) syringe scarcity contributing to syringe sharing; (4) linkages among decisions about syringe sharing and perceptions of HCV risk, HCV status, and interpersonal trust; and (5) confusion and misconceptions about HCV, including difficulty learning one's HCV status, inadequate HCV education, and misconceptions regarding HCV transmission and treatment. Efforts to prevent and eliminate HCV among rural PWID should expand syringe access, increase awareness of HCV as a serious but preventable risk, and acknowledge social connections as potential influences on syringe access and syringe-sharing decisions.

Health, harm reduction, and social service providers' perspectives on the appropriateness and feasibility of peer distribution of HIV self-test kits among people who use drugs. Harm Reduct J 2024; 21:29.

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

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

HCV serostatus and injection sharing practices among those who obtain syringes from pharmacies and directly and indirectly from syringe services programs in rural New England. Addict Sci Clin Pract 2023; 18:2. [PMID: 36597153 PMCID: PMC9809047 DOI: 10.1186/s13722-022-00358-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 12/14/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Among people who inject drugs (PWID), obtaining syringes via syringe services programs (SSPs) and pharmacies reduces injection sharing practices associated with hepatitis C virus (HCV). Whether indirect use of SSPs via secondary exchange confers a similar benefit remains unknown, particularly in rural settings. We compared HCV serostatus and injection sharing practices by primary syringe source among a sample of rural PWID. METHODS Data are from a cross-sectional study of adults who use drugs recruited from eleven rural counties in New Hampshire, Vermont, and Massachusetts using respondent-driven sampling (2018-2019). Study staff performed HCV antibody testing. An audio computer-assisted self-interview assessed sociodemographic characteristics, past 30-day injection practices, and past 30-day primary syringe source. Primary syringe source was classified as direct SSP, pharmacy, indirect SSP (secondary exchange), or "other" (friend/acquaintance, street seller, partner/relative, found them). Mixed effects modified Poisson models assessed the association of primary syringe source with HCV seroprevalence and injection sharing practices. RESULTS Among 397 PWID, the most common primary syringe source was "other" (33%), then pharmacies (27%), SSPs (22%), and secondary exchange (18%). In multivariable models, compared with those obtaining most syringes from "other" sources, those obtaining most syringes from pharmacies had a lower HCV seroprevalence [adjusted prevalence ratio (APR):0.85, 95% confidence interval (CI) 0.73-0.9985]; however, the upper bound of the 95% CI was close to 1.0. Compared with those obtaining most syringes from other sources, PWID obtaining most syringes directly from SSPs or pharmacies were less likely to report borrowing used syringes [APR(SSP):0.60, 95% CI 0.43-0.85 and APR(Pharmacies):0.70, 95% CI 0.52-0.93], borrowing used injection equipment [APR(SSP):0.59, 95% CI 0.50-0.69 and APR (Pharmacies):0.81, 95% CI 0.68-0.98], and backloading [APR(SSP):0.65, 95% CI 0.48-0.88 and APR(Pharmacies):0.78, 95% CI 0.67-0.91]. Potential inverse associations between obtaining most syringes via secondary exchange and injection sharing practices did not reach the threshold for statistical significance. CONCLUSIONS PWID in rural New England largely relied on informal syringe sources (i.e., secondary exchange or sources besides SSPs/pharmacies). Those obtaining most syringes from an SSP or pharmacy were less likely to share injection equipment/syringes and had a lower HCV seroprevalence, which suggests using these sources reduces the risk of new HCV infections or serves as proxy for past injection behavior.

Holeksa J. Dealing with low access to harm reduction: a qualitative study of the strategies and risk environments of people who use drugs in a small Swedish city. Harm Reduct J 2022; 19:23. [PMID: 35246162 PMCID: PMC8894830 DOI: 10.1186/s12954-022-00602-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 02/17/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND The development of harm reduction has been limited in many areas of Sweden. This study aims to understand the implications that this has for the life circumstances and risk management of people who use drugs in areas of low access. METHODS Eleven qualitative, semi-structured interviews were undertaken with people who use drugs in a small urban centre with no needle and syringe exchange program (NSP) or Housing First policy. RESULTS Participants reported many solutions to lack of NSP, including travel to an external NSP, creating bridging distribution networks, stealing, borrowing, reusing, ordering online, and smuggling injection equipment. They were at risk of having their equipment confiscated by police. Participants were mostly homeless, and to address exclusion from housing services, were forced to frequently find new temporary solutions, sheltering themselves in public places, with friends, in cars, among others. Participants felt the lack of services reflected stigmatized notions of drug use and heightened their exclusion from general society. For example, they avoided accessing other health care services for fear of discrimination. These issues caused high levels of stress and anxiety, in addition to serious risk for many somatic and psychological health conditions, including HIV and HCV transmission. CONCLUSION Lack of harm reduction services placed a great burden on study participants to develop strategies due to gaps in official programming. It also contributes to a vicious cycle of exclusion from services. The implementation of such evidence-based programs will reduce this burden, as well as provide the indirect, symbolic effect of inclusion.

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
Among adults living with HIV, unstable housing is a barrier to health. Stably- and unstably-housed adults living with HIV were assessed for over 25 months. At baseline, unstably-housed adults living with HIV had a more recent HIV diagnosis, higher viral loads, worse physical and mental health, lower rates of antiretroviral therapy use and insurance coverage, and higher rates of hard drug use than stably-housed adults living with HIV. At follow-up, the health of both groups was similar, but unstably-housed adults living with HIV reported significantly more hard drug use and mental health symptoms when compared to the stably-housed adults living with HIV. Drug and mental health risks decreased for both groups, but decreases in unprotected sex were greater among unstably-housed adults living with HIV.

Abstract
BACKGROUND Millions of street-connected children and young people worldwide live or work in street environments. They are vulnerable to many risks, whether or not they remain connected to families of origin, and despite many strengths and resiliencies, they are excluded from mainstream social structures and opportunities. OBJECTIVES Primary research objectivesTo evaluate and summarise the effectiveness of interventions for street-connected children and young people that aim to:• promote inclusion and reintegration;• increase literacy and numeracy;• facilitate access to education and employment;• promote mental health, including self esteem;• reduce harms associated with early sexual activity and substance misuse. Secondary research objectives• To explore whether effects of interventions differ within and between populations, and whether an equity gradient influences these effects, by extrapolating from all findings relevance for low- and middle-income countries (LMICs) (Peters 2004).• To describe other health, educational, psychosocial and behavioural effects, when appropriate outcomes are reported.• To explore the influence of context in design, delivery and outcomes of interventions.• To explore the relationship between numbers of components and duration and effects of interventions.• To highlight implications of these findings for further research and research methods to improve evidence in relation to the primary research objective.• To consider adverse or unintended outcomes. SEARCH METHODS We searched the following bibliographic databases, searched for the original review, from inception to 2012, and various relevant non-governmental and organisational websites: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE and Pre-MEDLINE; EMBASE and EMBASE Classic; Cumulative Index to Nursing and Allied Health Literature (CINAHL); PsycINFO; Education Resource Information Center (ERIC); Sociological Abstracts; Social Services Abstracts; Social Work Abstracts; Healthstar; Latin American Caribbean Health Sciences Literature (LILACS); System for Grey literature in Europe (OpenGrey); ProQuest Dissertations and Theses; EconLit; IDEAS Economics and Finance Research; JOLIS Library Catalog of the holdings of the World Bank Group and International Monetary Fund (IMF) Libraries; British Library for Development Studies (BLDS); Google and Google Scholar. We updated the search in April 2015 for the review update, using the same methods. SELECTION CRITERIA This review includes data from harm reduction or reintegration intervention studies that used a comparison group study design; all were randomised or quasi-randomised studies. Studies were included if they evaluated interventions provided for street-connected children and young people, from birth to 24 years, in all contexts. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed risk of bias and other factors presented in the Discussion and Summary quality assessment (Grades of Recommendation, Assessment, Development and Evaluation (GRADE)). We extracted data on intervention delivery, context, process factors, equity and outcomes, and grouped outcomes into psychosocial outcomes, risky sexual behaviours or substance use. We conducted meta-analyses for outcomes where the outcome measures were sufficiently similar. We evaluated other outcomes narratively. MAIN RESULTS We included 13 studies evaluating 19 interventions from high-income countries (HICs). We found no sufficiently robust evaluations conducted in low- and middle-income countries (LMICs). Study quality overall was low and measurements used by studies variable. Participants were classified as drop-in and shelter-based. No studies measured the primary outcome of reintegration and none reported on adverse effects.We found no consistent results on a range of relevant outcomes within domains of psychosocial health, substance misuse and sexually risky behaviours . Interventions evaluated consisted of time-limited therapeutically based programmes that proved no more effective than standard shelter or drop-in services and other control interventions used for most outcomes in most studies. Favourable changes from baseline were reported for outcomes for most participants following therapy interventions and standard services. We noted considerable heterogeneity between studies and inconsistent reporting of equity data. No studies measured the primary outcome of reintegration or reported on adverse effects. AUTHORS' CONCLUSIONS Analysis revealed no consistently significant benefit for focused therapeutic interventions compared with standard services such as drop-in centres, case management and other comparable interventions for street-connected children and young people. Commonly available services, however, were not rigorously evaluated. Robust evaluation of interventions, including comparison with no intervention, would establish a more reliable evidence base to inform service implementation. More robust research is needed in LMICs to examine interventions for street-connected children and young people with different backgrounds and service needs.

Factors associated with hepatitis B vaccine series completion in a randomized trial for injection drug users reached through syringe exchange programs in three US cities. BMC Public Health 2014; 14:820.

Abstract
Background Hepatitis B virus (HBV) is a vaccine preventable infection yet vaccination rates are low among injection drug users (IDUs) despite the high risk of infection and longstanding recommendations to promote vaccination. We sought to improve vaccination rates by reaching IDUs through syringe exchange programs (SEPs) in three U.S. cities. Methods IDUs were randomized in a trial comparing the standard HBV vaccination schedule (0, 1, and 6 months) to an accelerated schedule (0, 1, and 2 months) and participation data were analyzed to identify determinants of completion of the three-dose vaccine series. Independent variables explored included sociodemographics, injection and syringe access behaviors, assessment of health beliefs, HBV-associated knowledge, and personal health status. Results Covariates associated with completion of the three-dose vaccine series were accelerated vaccine schedule (aOR 1.92, 95% CI 1.34, 2.58, p = <0.001), older age (aOR 1.05, 95% CI 1.03, 1.07, p = <0.001), and poorer self-rated health score (aOR 1.26, 95% CI 1.05, 1.5, p = 0.02). Completion was less likely for those getting syringes from SEP customers than for SEP customers (OR 0.33, 95% CI 0.19, 0.58, p = <0.001). Conclusions SEPs should offer hepatitis vaccination in a manner that minimizes time between first and last visits by accelerating the dosing schedule. Public health interventions should target younger, less healthy, and non-SEP customer participants. Other health interventions at SEPs may benefit from similar approaches that reach out beyond regular SEP customers.

[PMID: 23973009 DOI: 10.1016/j.drugpo.2013.07.001] [Citation(s) in RCA: 212] [Impact Index Per Article: 19.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2012] [Revised: 06/25/2013] [Accepted: 07/03/2013] [Indexed: 01/23/2023]
Abstract
BACKGROUND Injecting drug use is a major risk factor for the acquisition and transmission of HIV and Hepatitis C virus (HCV). Prevention of these infections among people who inject drugs (PWID) is critical to reduce ongoing transmission, morbidity and mortality. METHODS A review of reviews was undertaken involving systematic literature searches of Medline, Embase, CINAHL, PsychINFO, IBSS and the Cochrane Library (2000-2011) to identify English language reviews regarding the effectiveness of harm reduction interventions in relation to HIV transmission, HCV transmission and injecting risk behaviour (IRB). Interventions included needle and syringe programmes (NSP); the provision of injection paraphernalia; opiate substitution treatment (OST); information, education and counselling (IEC); and supervised injecting facilities (SIFs). Reviews were classified into 'core' or 'supplementary' using critical appraisal criteria, and the strength of review-level evidence was assessed. RESULTS Twelve core and thirteen supplementary reviews were included. From these reviews we identified: (i) for NSP: tentative review-level evidence to support effectiveness in reducing HIV transmission, insufficient review-level evidence relating to HCV transmission, but sufficient review-level evidence in relation to IRB; (ii) for OST: sufficient review-level evidence of effectiveness in relation to HIV transmission and IRB, but tentative review-level evidence in relation to HCV transmission; (iii) for IEC, the provision of injection paraphernalia and SIFs: tentative review-level evidence of effectiveness in reducing IRB; and either insufficient or no review-level evidence for these interventions in relation to HIV or HCV transmission. CONCLUSION Review-level evidence indicates that harm reduction interventions can reduce IRB, with evidence strongest for OST and NSP. However, there is comparatively little review-level evidence regarding the effectiveness of these interventions in preventing HCV transmission among PWID. Further studies are needed to assess the effectiveness and impact of scaling up comprehensive packages of harm reduction interventions to minimise HIV and HCV transmission among PWID.

Abstract
BACKGROUND Numbers of street-connected children and young people run into many millions worldwide and include children and young people who live or work in street environments. Whether or not they remain connected to their families of origin, and despite many strengths and resiliencies, they are vulnerable to a range of risks and are excluded from mainstream social structures and opportunities. OBJECTIVES To summarise the effectiveness of interventions for street-connected children and young people that promote inclusion and reintegration and reduce harms. To explore the processes of successful intervention and models of change in this area, and to understand how intervention effectiveness may vary in different contexts.. SEARCH METHODS We searched the following bibliographic databases, from inception to 2012, and various relevant non-governmental and organisational websites: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE and PreMEDLINE; EMBASE and EMBASE Classic; CINAHL; PsycINFO; ERIC; Sociological Abstracts; Social Services Abstracts; Social Work Abstracts; Healthstar; LILACS; System for Grey literature in Europe (OpenGrey); ProQuest Dissertations and Theses; EconLit; IDEAS Economics and Finance Research; JOLIS Library Catalog of the holdings of the World Bank Group and IMF Libraries; BLDS (British Library for Development Studies); Google, Google Scholar. SELECTION CRITERIA The review included data from harm reduction or reintegration promotion intervention studies that used a comparison group study design and were all randomised or quasi-randomised studies. Studies were included if they evaluated interventions aimed to benefit street-connected children and young people, aged 0 to 24 years, in all contexts. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the risk of bias of included studies. Data were extracted on intervention delivery, context, process factors, equity and outcomes. Outcome measures were grouped according to whether they measured psychosocial outcomes, risky sexual behaviours or substance use. A meta-analysis was conducted for some outcomes though it was not possible for all due to differences in measurements between studies. Other outcomes were evaluated narratively. MAIN RESULTS We included 11 studies evaluating 12 interventions from high income countries. We did not find any sufficiently robust evaluations conducted in low and middle income countries (LMICs) despite the existence of many relevant programmes. Study quality overall was low to moderate and there was great variation in the measurement used by studies, making comparison difficult. Participants were drop-in and shelter based. We found no consistent results on a range of relevant outcomes within domains of psychosocial health, substance misuse and sexual risky behaviours despite the many measurements collected in the studies. The interventions being evaluated consisted of time limited therapeutically based programmes which did not prove more effective than standard shelter or drop-in services for most outcomes and in most studies. There were favourable changes from baseline in outcomes for most particpants in therapy interventions and also in standard services. There was considerable heterogeneity between studies and equity data were inconsistently reported. No study measured the primary outcome of reintegration or reported on adverse effects. The review discussion section included consideration of the relevance of the findings for LMIC settings. AUTHORS' CONCLUSIONS Analysis across the included studies found no consistently significant benefit for the 'new' interventions compared to standard services for street-connected children and young people. These latter interventions, however, have not been rigorously evaluated, especially in the context of LMICs. Robustly evaluating the interventions would enable better recommendations to be made for service delivery. There is a need for future research in LMICs that includes children who are on the streets due to urbanisation, war or migration and who may be vulnerable to risks such as trafficking.

Abstract
BACKGROUND There has been a significant increase in the provision of injecting paraphernalia from Scottish injecting equipment provision (IEP) services. However, there is currently a lack of evidence on whether uptake of paraphernalia has any impact on paraphernalia sharing among injecting drug users (IDU). The aim of this study was to examine the factors associated with paraphernalia sharing; in particular, whether uptake of filters, spoons and sterile water from IEPs is associated with a reduction in the sharing of these items. METHODS A cross-sectional voluntary anonymous survey of 2037 IDUs was administered during 2008-2009. Participants were asked whether they had shared filters, spoons or water (paraphernalia) in the previous 6 months, and their uptake of these items from an IEP during an average week in the previous 6 months. RESULTS Self-reported uptake of paraphernalia in an average week during the previous 6 months was associated with reduced odds of sharing paraphernalia: (i) uptake of >30 filters was associated with a reduced odds of sharing filters (adjusted odds ratio (AOR) 0.50, 95% confidence interval 0.32-0.79); (ii) uptake of >30 spoons was associated with a reduced odds of sharing spoons (AOR 0.46, 95% confidence interval 0.28-0.74); and (iii) uptake of sterile water was associated with a reduced odds of sharing water (AOR 0.36, 95% confidence interval 0.22-0.61) compared to no uptake of each of these items. CONCLUSIONS Uptake of paraphernalia appears to be associated with safer injecting practice. Further research is needed to establish the impact of paraphernalia provision on HCV transmission.

Abstract
Injection drug users (IDU) who use methamphetamine (MA) are at an increased risk of HIV infection due to engagement in injection-related risk behavior including syringe sharing. In this cohort study of young IDU aged 18-30, we investigated the relationship between injection MA use and syringe sharing, and whether difficulty accessing sterile syringes mediated this association. Behavioral questionnaires were completed by 384 IDU in Vancouver, Canada between October 2005 and May 2008. Generalized estimating equations were used to estimate direct and indirect effects. The median age of participants was 24 (IQR: 22–27) and 214 (55.7%) were male. Injecting MA was independently associated with syringe sharing. Mediation analyses revealed that difficulty accessing sterile syringes partially mediated the association between injecting MA and syringe sharing. Interventions to reduce syringe sharing among young methamphetamine injectors must address social and structural barriers to accessing HIV prevention programs.

Abstract
BACKGROUND A variety of legal, social and logistical factors can prevent individuals from accessing formal needle exchange programmes. One common solution to this problem is satellite exchange, which involves collaborating with people who already use an exchange to deliver needles and other supplies to those unable to access the exchange. While this approach can be very successful, one potential problem is that those most willing to deliver needles to their peers are often members of social networks that are already well connected with the needle exchange, leading to duplication of effort. In this paper we describe a simple and novel method for identifying groups of people who are demonstrably in need of improved access to needles, and for re-targeting efforts to meet the needs of those people. The method described was piloted at the Homeless Youth Alliance, San Francisco, USA, and further refined at Clean Needles Now, Los Angeles, USA. METHODS People accessing needle exchange sites were asked to participate in a survey with two questions: "where were you and what time was it last time someone borrowed a needle from you?" and "where were you and what time was it last time you had to borrow a needle from someone else?" Responses were geocoded, and maps produced showing 'hotspots' where people were frequently finding themselves without needles. RESULTS Satellite needle exchange was refined from an ad-hoc activity into one which focused on delivering needles to those with empirically demonstrable need. Maps produced in the process also proved valuable in discussions with local officials and other agencies about funding, as well as needle provision policy and practices. CONCLUSION We describe a method for rapidly assessing, describing, and responding to unmet and under-met need among injecting drug users. The method is particularly well-suited to organizations with extremely limited resources.

BMC Public Health 2010; 10:721. [PMID: 21092300 PMCID: PMC3001732 DOI: 10.1186/1471-2458-10-721] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2010] [Accepted: 11/23/2010] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Sharing drug injecting paraphernalia other than needles and syringes (N/S) has been implicated in the transmission of Hepatitis C virus (HCV) among injecting drug users (IDU). We aimed to determine whether the provision of sterile non-N/S injecting paraphernalia reduces injecting risk behaviours or HCV transmission among IDU. METHODS A systematic search of seven databases and the grey literature for articles published January 1989-February 2010 was undertaken. Thirteen studies (twelve observational and one non-randomized uncontrolled pilot intervention) were identified and appraised for study design and quality by two investigators. RESULTS No studies examined the association between the provision of non-N/S injecting paraphernalia and incident HCV infection. One cross-sectional study found that individuals who frequently, compared to those who infrequently, used sterile cookers and water, were less likely to report prevalent HCV infection. Another found no association between the uptake of sterile non-N/S injecting paraphernalia and self-reported sharing of this paraphernalia. The remaining observational studies used attendance at needle and syringe exchange programmes (NSP) or safer injection facilities (SIF) that provided non-N/S injecting paraphernalia as a proxy measure. Eight studies presented adjusted odds ratios, ranging from 0.3 to 0.9, suggesting a reduced likelihood of self-reported sharing of non-N/S injecting paraphernalia associated with use of NSP or SIF. There was substantial uncertainty associated with these estimates however. Three unadjusted studies reported a reduction in the prevalence of sharing of non-N/S injecting paraphernalia over time among NSP users. Only one study reported an adjusted temporal trend in the prevalence of sharing non-N/S injecting paraphernalia, finding higher rates among non-NSP users than NSP users at each time point, and a greater reduction in sharing among non-NSP than NSP users over time. Study limitations included the use of convenience samples, self-reported exposure and outcome measures, flawed classification of the exposed and unexposed groups, and inadequate adjustment for potential confounding variables. CONCLUSIONS The evidence to demonstrate that the provision of sterile non-N/S injecting paraphernalia reduces HCV transmission or modifies injecting risk behaviours is currently limited by an insufficient volume and quality of studies. Further research is required to inform practice and policy in this area.

Abstract
Syringe exchange programs (SEPs) can reduce HIV risk among injecting drug users (IDUs) but their use may depend heavily on contextual factors such as local syringe policies. The frequency and predictors of transitioning over time to and from direct, indirect, and non-use of SEPs are unknown. We sought, over one year, to: (1) quantify and characterize transition probabilities of SEP attendance typologies; (2) identify factors associated with (a) change in typology, and (b) becoming and maintaining Direct SEP use; and (3) quantify and characterize transition probabilities of SEP attendance before and after changes in policy designed to increase access. Using data collected from 583 IDUs participating in a three-city cohort study of SEPs, we conducted a latent transition analysis and multinomial regressions. Three typologies were detected: Direct SEP users, Indirect SEP users and Isolated IDUs. Transitions to Direct SEP use were most prevalent. Factors associated with becoming or maintaining Direct SEP use were female sex, Latino ethnicity, fewer injections per syringe, homelessness, recruitment city, injecting speedballs (cocaine and heroin), and police contact involving drug paraphernalia possession. Similar factors influenced transitions in the syringe policy change analysis. Policy change cities experienced an increase in Indirect SEP users (43-51%) with little increased direct use (29-31%). We found that, over time, IDUs tended to become Direct SEP users. Policies improving syringe availability influenced SEP use by increasing secondary syringe exchange. Interactions with police around drug paraphernalia may encourage SEP use for some IDUs and may provide opportunities for other health interventions.

Abstract
BACKGROUND Although street-involved youth who inject illicit drugs are known to be at an increased risk of HIV and other adverse health outcomes, little is known about public injecting among this population and how injecting in public environments may impact HIV risk behaviour. METHODS We used data derived from a study of 560 street-involved youth in Vancouver, Canada to examine the factors associated with injecting in public environments among youth who reported injecting drugs in the past 6 months. RESULTS At baseline, 162 (28.9%) reported injecting drugs in the past 6 months. Among injectors, the 124 (76.5%) participants who reported injecting in public were more likely to be homeless (odds ratio [OR]=6.39, p<0.001), engage in unprotected intercourse (OR=3.09, p=0.004), deal drugs (OR=2.26, p=0.032), smoke crack cocaine (OR=3.00, p=0.005), inject heroin (OR=3.48, p=0.001), drop used syringes outdoors (OR=8.44, p<0.001), share syringes (OR=4.43, p=0.004), and were less likely to clean injection sites >75% of the time (OR=0.36, p=0.008). The majority (62.1%) reported feeling rushed while injecting in public. CONCLUSIONS Youth who inject in public are significantly more likely to engage in sexual and injection-related risk behaviour. Given the known elevated rates of HIV infection and other harms among this population, youth-focused interventions that target both sexual and drug-related risks associated with public drug-using environments are in urgent need of evaluation.

Abstract
BACKGROUND Many opioid-dependent patients do not receive care for addiction issues when hospitalized for other medical problems. Based on 3 years of clinical practice, we report the Transitional Opioid Program (TOP) experience using hospitalization as a "reachable moment" to identify and link opioid-dependent persons to addiction treatment from medical care. METHODS A program nurse identified, assessed, and enrolled hospitalized, out-of-treatment opioid-dependent drug users based on their receipt of methadone during hospitalization. At discharge, patients transitioned to an outpatient interim opioid agonist program providing 30-day stabilization followed by 60-day taper. The nurse provided case management emphasizing HIV risk reduction, health education, counseling, and medical follow-up. Treatment outcomes included opioid agonist stabilization then taper or transfer to long-term opioid agonist treatment. RESULTS From January 2002 to January 2005, 362 unique hospitalized, opioid-dependent drug users were screened; 56% (n = 203) met eligibility criteria and enrolled into the program. Subsequently, 82% (167/203) presented to the program clinic post-hospital discharge; for 59% (119/203) treatment was provided, for 26% (52/203) treatment was not provided, and for 16% (32/203) treatment was not possible (pursuit of TOP objectives precluded by medical problems, psychiatric issues, or incarceration). Program patients adhered to a spectrum of medical recommendations (e.g., obtaining prescription medications, medical follow-up). CONCLUSIONS The Transitional Opioid Program (TOP) identified at-risk hospitalized, out-of-treatment opioid-dependent drug users and, by offering a range of treatment intensity options, engaged a majority into addiction treatment. Hospitalization can be a "reachable moment" to engage and link drug users into addiction treatment.

Abstract
Harm reduction is both a policy approach and used to describe a specific set of interventions. These interventions aim to reduce the harms associated with drug use. Employing a strict definition of harm reduction, evidence for the efficacy and effectiveness of alcohol, tobacco and illicit drug harm reduction interventions were reviewed. Systematic searches of the published literature were undertaken. Studies were included if they provided evaluation data (pre-post, or control group comparisons). More than 650 articles were included in the review. The majority of the literature concerned illicit drugs. For alcohol, harm reduction interventions to reduce road trauma are well-founded in evidence. Otherwise, there is limited research to support the efficacy and effectiveness of other alcohol harm reduction interventions. For tobacco, the area is controversial but promising new products that reduce the harms associated with smoking are being developed. In the area of illicit drugs there is solid efficacy, effectiveness and economic data to support needle syringe programmes and outreach programmes. There is limited published evidence to date for other harm reduction interventions such as non-injecting routes of administration, brief interventions and emerging positive evidence for supervised injecting facilities. There is sufficient evidence to support the wide-spread adoption of harm reduction interventions and to use harm reduction as an overarching policy approach in relation to illicit drugs. The same cannot be concluded for alcohol or tobacco. Research at a broad policy level is required, especially in light of the failure by many policy makers to adopt cost-effective harm reduction interventions.

OBJECTIVES We examined the efficacy of the Healthy Living Program in reducing risky sexual behavior and substance use among adults with HIV infection who were marginally housed (i.e., homeless at some point over a 37-month period). METHODS We had previously conducted a randomized controlled trial with 936 adults living with HIV infection. In that study, 3 intervention modules of 5 sessions each addressed different goals: reducing risky sexual acts and drug use, improving the quality of life, and adhering to healthful behaviors. Participants were interviewed at baseline and at 5, 10, 15, 20, and 25 months; 746 completed 4 or more assessments. In this study, we analyzed sexual behavior and drug use outcomes for the 35% (n = 270 of 767) of participants who were considered marginally housed. RESULTS Among the marginally housed participants, there were significantly greater reductions in unprotected risky sexual acts, the number of sexual partners of HIV negative or unknown serostatus, alcohol or marijuana use, and hard drug use among the intervention group than among the control group. CONCLUSIONS Intensive, skill-focused intervention programs may improve the lives of marginally housed adults living with HIV infection.

Abstract
Throughout the US, high-visibility drug markets are concentrated in neighborhoods with few economic opportunities, while drug buyers/users are widely dispersed. A study of Pittsburgh Syringe Exchange participants provides data on travel between and network linkages across neighborhoods with different levels of drug activity. There are distinct racial patterns to syringe distribution activity within networks and across neighborhoods. Pittsburgh's history suggests these patterns emerge from historical patterns of social and economic development. Study data demonstrate the ability of IDUs to form long term social ties across racial and geographic boundaries and use them to reduce the risk of HIV transmission.

Abstract
Secondary syringe exchange (SSE) refers to the exchange of sterile syringes between injection drug users (IDUs). To date there has been limited examination of SSE in relation to the social networks of IDUs. This study aimed to identify characteristics of drug injecting networks associated with the receipt of syringes through SSE. Active IDUs were recruited from syringe exchange and methadone treatment programs in Montreal, Canada, between April 2004 and January 2005. Information on each participant and on their drug-injecting networks was elicited using a structured, interviewer-administered questionnaire. Subjects' network characteristics were examined in relation to SSE using regression models with generalized estimating equations. Of 218 participants, 126 were SSE recipients with 186 IDUs in their injecting networks. The 92 non-recipients reported 188 network IDUs. Networks of SSE recipients and non-recipients were similar with regard to network size and demographics of network members. In multivariate analyses adjusted for age and gender, SSE recipients were more likely than non-recipients to self-report being HIV-positive (OR=3.56 [1.54-8.23]); require or provide help with injecting (OR=3.74 [2.01-6.95]); have a social network member who is a sexual partner (OR=1.90 [1.11-3.24]), who currently attends a syringe exchange or methadone program (OR=2.33 [1.16-4.70]), injects daily (OR=1.77 [1.11-2.84]), and shares syringes with the subject (OR=2.24 [1.13-4.46]). SSE is associated with several injection-related risk factors that could be used to help focus public health interventions for risk reduction. Since SSE offers an opportunity for the dissemination of important prevention messages, SSE-based networks should be used to improve public health interventions. This approach can optimize the benefits of SSE while minimizing the potential risks associated with the practice of secondary exchange.

Abstract
Using cross-sectional analysis we examined residential status and associated differences in HIV risk behaviors among 3266 young IDUs enrolled in an HIV prevention trial. A three-level outcome (homeless (37%), equivocally housed (17%), housed (46%)) was defined based on responses to two questions assessing subjective and objective criteria for homelessness: "equivocally housed" participants were discordant on these measures. In multivariate analysis, antecedents of homelessness were having lived in an out-of-home placement, been thrown out of the home or in juvenile detention, and experienced childhood abuse; while correlates included receiving income from other and illegal sources, drinking alcohol or using methamphetamine at least daily, using shooting galleries, backloading, and sex work. A subset of these variables was associated with being equivocally housed. HIV risk varies by housing status, with homeless IDUs at highest risk. Programs for IDUs should utilize a more specific definition of residential status to target IDUs needing intervention.

Abstract
Effective prevention of syringe-borne transmission of HIV and the hepatitis viruses can be undermined if contact between injection drug users and the staff of prevention programs is impeded by police harassment, limited program resources, and the absence of an open "drug scene." All these are commonplace in the Russian Federation. In response, "Project Renewal," the harm reduction program of the AIDS Prevention and Control Center of the Tatarstan Ministry of Health in Kazan, has created a hybrid syringe exchange program that as its primary focus recruited and trained volunteers to provide secondary syringe exchange. To compensate for operational barriers, the program staff identified private venues and trained responsible individuals to work through their own and related networks of injectors to provide clean syringes, other harm reduction supplies, and educational materials, while facilitating the collection and removal of used and potentially contaminated syringes. Program staff developed a detailed set of tracking instruments to monitor, on a daily and weekly basis, the locations and types of contacts and the dissemination of trainings and materials to ensure that the secondary distribution network reaches its target audience. Data show that these secondary exchange sites have proven more productive than the primary mobile and fixed-site syringe exchanges in Kazan. Beginning in 2001, Project Renewal has trained other harm reduction programs in the Russian Federation to use this model of reaching injectors, identifying and training volunteers, and monitoring results of secondary syringe exchange.

Abstract
Where authorized access to needles and syringes from exchanges and pharmacies is limited, secondary exchange (SE) can provide an important source of sterile injecting equipment. Interventions can be developed to use SE to facilitate needle and syringe exchange programs to reach a wider population of drug injectors. Yet in a context such as Western Australia, where needles and syringes are available to drug injectors from many authorized sources, the added benefit of SE is unknown. This review of data and literature conducted in October 2003 shows potential benefits but also concerns about undermining vulnerable public and political support for authorized needle provision schemes that has been nurtured and supported over a number of years.

Abstract
This article assesses the operations of Porto Alegre, State of Rio Grande do Sul, (southern Brazil) needle exchange program (NEP), a setting where HIV infection rates have been on the rise among injection drug users (IDUs) in recent years, contrasting with substantial declines observed in this population, in major Brazilian cities (located in the southeast and southernmost part of Brazilian northeast). We explored local syringe dynamics, with the exclusive delivery in the local NEP of tagged syringes, and the subsequent monitoring of returned tagged/untagged used syringes from January to September 2002. We further assessed local NEP operations using focus groups and field observation, trying to expose the underlying reasons for the substantial delay in the return of tagged syringes and the continuous and relevant return of untagged syringes throughout the study period. We found that local IDUs reuse, divert, and create caches of syringes at their discretion. All efforts should be made to increase the availability of clean syringes and to fully integrate syringe exchange with comprehensive health education and health screening to effectively curb HIV spread.

Abstract
This first international review of the evidence that needle syringe programs reduce HIV infection among injecting drug users found that conservative interpretation of the published data fulfills six of the nine Bradford Hill criteria (strength of association, replication of findings, temporal sequence, biological plausibility, coherence of evidence, and reasoning by analogy) and all six additional criteria (cost-effectiveness, absence of negative consequences, feasibility of implementation, expansion and coverage, unanticipated benefits, and application to special populations). The Bradford Hill criteria are often used to evaluate public health interventions. The principal finding of this review was that there is compelling evidence of effectiveness, safety, and cost-effectiveness, consistent with seven previous reviews conducted by or on behalf of U.S. government agencies. Authorities in countries affected or threatened by HIV infection among injecting drug users should carefully consider this convincing evidence now available for needle syringe programs with a view to establishing or expanding needle syringe programs to scale.

Abstract
This article describes the secondary syringe exchange (SSE) practices of injection drug users (IDUs) attending 23 syringe exchange programs (SEPs) in the state of California during 2002 (n=539). The sample was primarily heroin injecting, about two thirds male, half White and half other racial/ethnic groups. Participants were interviewed with a structured questionnaire that included items on sociodemographic factors, drug use practices, sexual practices, use of SEP and other social services, and satisfaction with SEP services. Interviews lasted about 30 minutes. SSE was highly prevalent: 75% of IDUs reported participating in SSE in the 6 months before interview. Program characteristics, such as legal status, SSE policy, and exchange policy, did not affect the prevalence of SSE among SEP clients. Infectious disease risk behaviors were significantly more common among SSE participants than nonparticipants. SSE participants were more likely to share syringes (p<.001) and cookers (p<.001) in the previous 6 months. SSE was significantly associated with being stuck with another person's syringe (needle-stick), a little-discussed "occupational hazard" of this practice. In multivariate analysis, the adjusted odds ratio of needle-stick among SSE participants was 2.8 (95% confidence interval, 1.3, 6.0). The high prevalence of SSE and the infectious disease risk associated with it warrant additional research to determine the causality of these associations. In the interim, SEPs should consider reinforcing HIV prevention education messages and training IDUs who engage in SSE in safe handling of biohazardous materials.

Abstract
This study examines HIV risk practices associated with secondary needle exchange, obtaining needles from a needle exchange program (NEP) through others who attend in person. We analyzed data from NEP logs, a survey and HIV testing from 901 drug injectors who (a) always visited NEPs themselves to get needles (primary-only NEP users), (b) obtained at least some NEP needles by having others exchange for them (mixed/secondary NEP users), and (c) obtained no needles from an NEP. About 22% of 40,000 NEP visits involved secondary exchanges, and these accounted for over half of all needles exchanged. In multiple logistic regression analyses, primary-only needle exchange was significantly associated with lower levels of receptive needle sharing, backloading, sharing other injection equipment and lending used needles, and positively associated with obtaining drug treatment. Mixed/secondary needle exchange was associated with less receptive needle sharing and a greater likelihood of drug treatment. Secondary exchange facilitated HIV risk reduction but the salutary effects of NEPs were attenuated in mixed/secondary exchangers.

Abstract
Young people aged 15–24 years account for fifty percent of all new AIDS cases worldwide. Moreover, half of all new HIV infections are associated with injection drug use. The average age for initiation into injecting drug use is 20 years of age. This paper investigates whether HIV prevention programs have reduced risk behaviours in young people.

Abstract
Syringe-exchange programs (SEPs) have proven to prevent the spread of bloodborne pathogens, primarily human immunodeficiency virus (HIV), among injection drug users (IDUs). In the United States, only about 7% of IDUs have access to and use SEPs. Some IDUs engage in secondary syringe exchange (SSE), meaning that one IDU (a "provider") obtains syringes at an SEP to distribute to other IDUs ("recipients"). This formative qualitative research was conducted to understand why and how IDUs engage in SSE to aid in the development of a large-scale peer HIV prevention intervention. Interviews with 47 IDUs in Oakland and Richmond, California, indicated that SSE was embedded in existing social networks, which provided natural opportunities for peer education. SSE providers reported a desire to help other IDUs as their primary motivation, while recipients reported convenience as their primary reason for using SSE. Building SSE into SEP structures can facilitate an effective provision of risk reduction supplies and information to IDUs who do not access SEPs directly.

Abstract
OBJECTIVE The goal of our study was to elucidate characteristics of persons likely to transition into injection drug use so that an identifiable group with high-risk for blood-borne infection may be targeted for interventions. METHODS An age-matched case-control analysis was performed from a cohort study in Baltimore, 1997-1999, of street-recruited non-injection and injection drug users (IDUs), aged 15-30. Cases were IDUs injecting < or = 2 years and controls were age-matched persons who used non-injection heroin, cocaine or crack. At baseline, all were interviewed about prior year-by-year behaviors; analysis using conditional logistic regression was based on information for the year prior to injection onset for the case and the same calendar time for the controls as well as recent behaviors for both groups. RESULTS Of 270 participants, most were African American (78%), female (61%), and HIV seroprevalence was 7% at baseline. IDUs were significantly more likely than controls to be non-African American (adjusted odds ratio (AOR)=0.09) and report high school dropout (AOR=2.32), early sex-trading (AOR=2.72), and recent violence victimization (AOR=9.28). CONCLUSION Given that new injectors are at high-risk for HIV and hepatitis yet difficult to reach for prevention efforts, our data suggest some categories to use to target non-injectors who are likely to transition into injection use.
