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
Objectives Sexually transmitted infections (STI) have been on the rise in the United States with racial/ethnic minority groups, gay and bisexual men, and youth experiencing the highest STI and HIV infection rates. In 2022, California became the first state in the nation to pass legislation, Senate Bill 306 (SB 306), requiring health care plans to cover the costs of home test kits for STIs, including HIV. This study examines provisions within SB 306 and its potential to reduce STI and HIV disparities among key demographic groups and geographic regions within California. Study design Ecological cross-sectional study involving 58 California counties. Methods Descriptive statistics and choropleth maps compared HIV/STI prevalence rates, uninsured rates, demographic composition, and healthcare provider coverage across California counties. Three geographically weighted Poisson regression analyses were conducted to separately examine the association between proportion of uninsured and HIV, gonorrhea, and chlamydia prevalence rates. Results HIV/STI rates were significantly and positively associated with the proportion of uninsured residents in Central and Southern California counties. These counties had a higher proportion of demographic groups vulnerable to HIV/STI including a large Latino, Black/African American, and younger (age 15-24) population but had a lower rate of healthcare providers with prescription authority for home testing kits, which is a requirement under SB 306. Conclusions Cutting-edge solutions are needed to stem the rising tide of new STI and HIV infections. While SB 306 is novel and innovative in intent, its coverage gaps will increase disparities and inequities among historically underserved populations.

The impact of the COVID-19 pandemic on people who inject drugs accessing harm reduction services in an rural American state. Harm Reduct J 2022; 19:80. [PMID: 35869523 PMCID: PMC9305035 DOI: 10.1186/s12954-022-00660-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 07/05/2022] [Indexed: 12/01/2022] Open
Abstract
Background The impact of public health policies during the COVID-19 pandemic on people who inject drugs (PWID) has varied across regions. In other countries, recent research has shown that PWID access to harm reduction services, despite rapid adaptations, has been negatively impacted. Our study describes these impacts in a rural state. Methods We conducted semi-structured interviews with PWID, community partners, and healthcare providers in the rural state of Maine (USA). We explored how changes made during the pandemic impacted access to harm reduction services, including basic services (i.e., shelter), syringe service programs, safe drug supply, low barrier treatment, and peer support. Interviews were analyzed using the framework method to apply Penchansky’s model of access, with Saurman’s modification, which includes six dimensions of access—accessibility, availability, acceptability, affordability, accommodation, awareness. Results We interviewed thirty-six stakeholders (N = 9 community partners, N = 9 healthcare providers, N = 18 PWID). Policies such as mobile outreach expansion, mail delivery of equipment, and relaxed telemedicine regulations facilitated accessibility to syringe service programs and low barrier buprenorphine treatment. Public health policies, such as social distancing and screening policies, reduced contact, which subsequently reduced acceptability and awareness of many services. Elimination of the one-for-one needle exchange in some areas increased, acceptability (i.e., perception of service), and affordability for PWID. However, some areas actually began enforcing a one-for-one needle exchange policy, which reduced affordability, acceptability, and awareness of services. Conclusions Changes resulting from the COVID-19 pandemic have impacted all dimensions of access to harm reduction services among PWID. While some barriers to harm reduction services were unavoidable during the pandemic, we found that specific policy decisions mitigated service barriers, while other policies exacerbated them. Relaxing needle exchange policies were particularly helpful in facilitating access to harm reduction services by giving community organizations flexibility to adapt to the evolving needs of PWID. These results can inform policies and service delivery to optimally mitigate the negative impacts on PWID during, and beyond, the pandemic.

Abstract
Ensuring people who inject drugs (PWID) have ≥ 100% sterile syringe coverage (i.e., persons have access to a sterile syringe for all injections) is optimal for HIV prevention. Existing syringe coverage literature is informative, yet little work has examined syringe coverage among PWID in rural communities. Using data from a 2018 PWID population estimation study conducted in a rural county in West Virginia, we used logistic regression to identify correlates of adequate sterile syringe coverage (at least 100%). A minority (37%) of PWID reported having adequate syringe coverage. Factors inversely associated with adequate syringe coverage included having recently (past 6 months): engaged in transactional sex work, shared syringes, and injected fentanyl. Having exclusively acquired syringes from a syringe services program was associated with increased odds of adequate syringe coverage. Rural PWID may benefit from tailored interventions designed to increase sterile syringe access.

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
OBJECTIVE Law is an important factor in the diffusion of syringe services programs (SSPs). This study measures the current status of, and 5-year change in, state laws governing SSP operations and possession of syringes by participants. METHODS Legal researchers developed a cross-sectional data set measuring key features of state laws and regulations governing the possession and distribution of syringes across the 50 US states and the District of Columbia in effect on August 1, 2019. We compared these data with previously collected data on laws as of August 1, 2014. RESULTS Thirty-nine states (including the District of Columbia) had laws in effect on August 1, 2019, that removed legal impediments to, explicitly authorized, and/or regulated SSPs. Thirty-three states had 1 or more laws consistent with legal possession of syringes by SSP participants under at least some circumstances. Changes from 2014 to 2019 included an increase of 14 states explicitly authorizing SSPs by law and an increase of 12 states with at least 1 provision reducing legal barriers to SSPs. Since 2014, the number of states explicitly authorizing SSPs nearly doubled, and the new states included many rural, southern, or midwestern states that had been identified as having poor access to SSPs, as well as states at high risk for HIV and hepatitis C virus outbreaks. Substantial legal barriers to SSP operation and participant syringe possession remained in >20% of US states. CONCLUSION Legal barriers to effective operation of SSPs have declined but continue to hinder the prevention and reduction of drug-related harm.

Abstract
In 2019, President Trump announced a new initiative, Ending the HIV Epidemic: A Plan for America (EHE). EHE will use 3 key strategies-diagnose, treat, and prevent-to reduce new HIV infections at least 90% by 2030, as well as new laboratory methods and epidemiological techniques to respond quickly to potential outbreaks. Partnerships are an important component in the initiative's success. Pharmacists and pharmacies can play important roles in EHE, including dispensing antiretroviral therapy and providing HIV screening, adherence counseling, medication therapy management, preexposure prophylaxis, and nonprescription syringe sales. The objective of this report is to discuss potential roles that pharmacists and pharmacies can play under the key strategies of EHE.

Abstract
Background To assess the structure of individual-level needle and syringe coverage measurement formula, and to estimate the impact of coverage-related behaviours/parameters (instances of syringe acquisition, total syringes acquired, peer-to-peer syringe distribution, injecting frequency) on overall coverage. Methods Data are drawn from the Melbourne (Australia) injecting drug user cohort study, 2010-16. Data from 518 participants were analysed. We used correlations to explore the relationships between coverage parameters; pooled multiple-linear regression to estimate the effect of each parameter on coverage over time; and exploratory factor analysis to assess the relevance of each parameter within the coverage formula. Results A 1-unit increase in injecting frequency over time reduced coverage by 10.93 percentage points, almost twice as much as other coverage parameters. Factor analysis results indicated potential improvements to coverage formula structure. Conclusions Our results suggest that reducing injecting frequency amongst people who inject drugs has the largest improvement in coverage levels, indicating harm reduction services should prioritize it. We also demonstrate that coverage measurement has been inconsistent to date. We sought to refine the method to assist in generating comparable research.

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 Using a new needle for every injection can reduce the spread of infectious disease among people who inject drugs (PWID). No previous study has examined new needle use barriers among PWIDs residing in the rural Appalachian part of the United States, an area currently in the midst of a heroin epidemic. Objective Therefore, our primary aim was to explore self-reported barriers to using a new needle by PWID attending a needle exchange program (NEP). Methods We conducted a cross-sectional survey of PWID attending two NEPs in rural West Virginia located in the heart of Central Appalachia. A convenience sample of PWID (n = 100) completed the Barriers to Using New Needles Questionnaire. Results The median number of barriers reported was 5 (range 0–19). Fear of arrest by police (72% of PWID “agreed” or “strongly agreed”) and difficulty with purchasing needles from a pharmacy (64% “agreed” or “strongly agreed”) were the most frequently cited barriers. Conclusions/Importance Congruent with previous findings from urban locations, in rural West Virginia, the ability of PWID to use a new needle obtained from a needle exchange for every injection may be compromised by fear of arrest. In addition, pharmacy sales of new needles to PWID may be blunted by an absence of explicit laws mandating nonprescription sales. Future studies should explore interventions that align the public health goals of NEPs with the occupational safety of law enforcement and health outreach goals of pharmacists.

Abstract
Distance to health services is known to be negatively associated with usage and needle and syringe programs (NSPs) for people who inject drugs (PWID) are no different. Australia has a mixture of NSP modalities (primary or secondary fixed-site NSPs), which may present unique barriers to access. In this study, we explore 1) the effect of distance to NSPs on individual-level needle and syringe coverage, and 2) differences in coverage dependent on NSP modality. Using data from 219 PWID in an ongoing cohort study in Melbourne, Australia, we measured the straight-line distance from participants’ residence to their nearest primary or secondary fixed-site NSP. We analysed the relationship between geographical distance and coverage via regression analysis. The median distance to any type of NSP was 1872 metres. Regardless of service type, 52% of participants lived within 2 kms of a fixed-site NSP and 87% lived within 5 kms. We found no association between distance to NSPs and syringe coverage or a significant difference in coverage by nearest service type. Our findings suggest that the number and distribution of NSPs in Melbourne, Australia caters adequately for the population of PWID.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2018; 62:51-58. [PMID: 30359873 DOI: 10.1016/j.drugpo.2018.08.019] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2018] [Revised: 08/21/2018] [Accepted: 08/27/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND Increased access to sterile syringes has been shown to reduce HIV risk among people who inject drugs (PWID). Where syringe services programs (SSPs) are limited, pharmacies are an important sterile syringe source. We assessed factors associated with using pharmacies as the primary source of syringes among PWID from 20 US cities. METHODS PWID ages ≥18 years were recruited for the 2015 National HIV Behavioral Surveillance using respondent-driven sampling. Using generalized estimating equation (GEE) models, we assessed demographic characteristics independently associated with participant-reported primary syringe source: pharmacies vs. SSPs. We calculated associations between primary syringe source and various behavioural outcomes, adjusted for participant characteristics. RESULTS PWID who were <30 years old, female, white, and less frequent injectors were more likely have used pharmacies as their primary syringe source. Accessing syringes primarily from pharmacies, as compared to SSPs, was associated with receptive syringe sharing and unsafe syringe disposal; using sterile syringes, recent HIV testing and participation in an HIV behavioural intervention were negatively associated with primary pharmacy use. CONCLUSIONS Pharmacies can play an important role in comprehensive HIV prevention among PWID. Linkage to HIV interventions and syringe disposal services at pharmacies could strengthen prevention efforts for PWID who cannot access or choose not to utilize SSPs.

Abstract
INTRODUCTION AND AIMS Services provided by needle and syringe programs (NSP) within Australia are easily accessible by international standards. However, important variation in NSP policy remains across Australian jurisdictions. The potential impacts of these variations on program operation for clients have not been systematically analysed in Australia. In this paper we conduct a preliminary examination to compare individual-level syringe coverage between and within Australian capital cities. DESIGN AND METHODS Participants were 2498 people who inject drugs (PWID) recruited from all Australian capital cities as part of the annual Illicit Drug Reporting System PWID survey over the period 2014-2016. Insufficient coverage was defined when <100% of a participant's injecting episodes were 'covered' by sterile needles and syringes. We report the percentage of insufficient coverage for each capital city for each year, and present descriptive statistics for coverage parameters, and an alternative measure for insufficient coverage, as Supporting Information. RESULTS Differences in behaviours that have the potential to impact syringe coverage were highly variable over time and place leading to variations in levels of insufficient coverage between and within all cities. Overall, insufficient coverage was most evident in larger cities where insufficient coverage varied between 19% and 23% (Sydney) over time, compared to smaller cities with variation from 9% to 12% (Adelaide). DISCUSSION AND CONCLUSIONS We found no consistent pattern of differences in individual-level needle and syringe coverage between and within Australian capital cities. Further work is needed to fully evaluate whether policy variation between Australian jurisdictions impacts on NSP coverage.

Abstract
Infectious disease remains a significant social and health concern in the United States. Preventing more people from contracting HIV/AIDS or Hepatitis C (HCV), requires a complex understanding of the interconnection between the biomedical and social dimensions of infectious disease. Opiate addiction in the US has skyrocketed in recent years. Preventing more cases of HIV/AIDS and HCV will require dealing with the social determinants of health. Needle exchange programs (NEPs) are based on a harm reduction approach that seeks to minimize the risk of infection and damage to the user and community. This article presents an exploratory small-scale quantitative study of the injection drug using habits of a group of injection drug users (IDUs) at a needle exchange program in Fresno, California. Respondents reported significant decreases in high risk IDU behaviors, including sharing of needles and to a lesser extent re-using of needles. They also reported frequent use of clean paraphernalia. Greater collaboration between social and health outreach professionals at NEPs could provide important frontline assistance to people excluded from mainstream office-based services and enhance efforts to reduce HIV/AIDS or HCV infection.

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
BACKGROUND The two largest needle exchange programs (NEPs) in Hungary were forced to close down in the second half of 2014 due to extreme political attacks and related lack of government funding. The closures occurred against a background of rapid expansion in Hungary of injectable new psychoactive substances, which are associated with very frequent injecting episodes and syringe sharing. The aim of our analysis was to predict how the overall Hungarian NEP syringe supply was affected by the closures. METHODS We analyzed all registry data from all NEPs in Hungary for all years of standardized NEP data collection protocols currently in use (2008-2014) concerning 22 949 client enrollments, 9,211 new clients, 228,167 client contacts, 3,160,560 distributed syringes, and 2,077,676 collected syringes. RESULTS We found that while the combined share of the two now closed NEPs decreased over time, even in their partial year 2014 they still distributed and collected about half of all syringes, and attended to over half of all clients and client contacts in Hungary. The number of distributed syringes per PWID (WHO minimum target = 100) was 81 in 2014 in Hungary, but 39 without the two now closed NEPs. CONCLUSIONS There is a high probability that the combination of decreased NEP coverage and the increased injection risk of new psychoactive substances may lead in Hungary to a public health disaster similar to the HIV outbreaks in Romania and Greece. This can be avoided only by an immediate change in the attitude of the Hungarian government towards harm reduction.

Abstract
INTRODUCTION AND AIMS People who inject drugs (PWID) engage in practices that put them at risk for various infections and overdose. The primary aim of this study was to examine common barriers to engaging in two risk reduction practices - cleaning one's skin at the injection site and always using new needles to inject - among heroin injectors in Denver, CO. METHOD In 2010, 48 PWIDs were recruited through street outreach and completed a structured interview that included questions on the frequency of specific risk reduction practices (skin cleaning and using new needles) and barriers associated with these practices. RESULTS Though many of the reported barriers were similar across the two practices, the most common barriers associated with skin cleaning included being in withdrawal and not being prepared with materials prior to injection. Fear of being arrested and being in withdrawal were most frequently reported for using new needles. Multivariate and t-test analyses demonstrated that individuals who skin cleaned and used new needles more frequently reported less barriers to these practices. CONCLUSIONS Participants reported a number of barriers to risk reduction, including those that are within the personal control of the injector, barriers that are consequences of addiction or psychological problems, and those that are structural or a function of the risk environment. Statistical analysis found that PWIDs who were more likely to skin clean and use new needles reported less barriers. Addressing barriers when intervening with PWID appears important to increase the success of risk reduction interventions.

Abstract
Background The incidence of HIV among persons who inject drugs (PWIDU) has fallen in many nations, likely due to successes of clean needle/syringe exchange and substance abuse treatment and service programs. However in Pakistan, prevalence rates for PWID have risen dramatically. In several cities, prevalence exceeded 20% by 2009 compared to a 2003 baseline of just 0.5%. However, no cohort study of PWID has ever been conducted. Methods We enrolled a cohort of 636 HIV seronegative PWID registered with three drop-in centers that focus on risk reduction and basic social services in Karachi. Recruitment began in 2009 (March to June) and PWID were followed for two years. We measured incidence rates and risk factors associated with HIV seroconversion. Results Incidence of HIV was 12.4 per 100 person-years (95% exact Poisson confidence interval [CI]: 10.3–14.9). We followed 474 of 636 HIV seronegative persons (74.5%) for two years, an annual loss to follow-up of <13 per 100 person years. In multivariable Cox regression analysis, HIV seroconversion was associated with non-Muslim religion (Adjusted risk ratio [ARR] = 1.7, 95%CI:1.4, 2.7, p = 0.03), sharing of syringes (ARR = 2.3, 95%CI:1.5, 3.3, p<0.0001), being homeless (ARR = 1.7, 95%CI:1.1, 2.5, p = 0.009), and daily injection of drugs (ARR = 1.1, 95%CI:1.0, 1.3, p = 0.04). Conclusions Even though all members of the cohort of PWID were attending risk reduction programs, the HIV incidence rate was very high in Karachi from 2009–2011. The project budget was low, yet we were able to retain three-quarters of the population over two years. Absence of opiate substitution therapy and incomplete needle/syringe exchange coverage undermines success in HIV risk reduction.

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
Despite the 2010 repeal of the ban on spending federal monies to fund syringe exchange programs (SEPs) in the U.S.A., these interventions--and specifically SEP site locations--remain controversial. To further inform discussions about the location of SEP sites, this longitudinal multilevel study investigates the relationship between spatial access to sterile syringes distributed by SEPs in New York City (NYC) United Hospital Fund (UHF) districts and injecting with an unsterile syringe among injectors over time (1995-2006). Annual measures of spatial access to syringes in each UHF district (N = 42) were created using data on SEP site locations and site-specific syringe distribution data. Individual-level data on unsterile injecting among injectors (N = 4,067) living in these districts, and on individual-level covariates, were drawn from the Risk Factors study, an ongoing cross-sectional study of NYC drug users. We used multilevel models to explore the relationship of district-level access to syringes to the odds of injecting with an unsterile syringe in >75% of injection events in the past 6 months, and to test whether this relationship varied by district-level arrest rates (per 1,000 residents) for drug and drug paraphernalia possession. The relationship between district-level access to syringes and the odds of injecting with an unsterile syringe depended on district-level arrest rates. In districts with low baseline arrest rates, better syringe access was associated with a decline in the odds of frequently injecting with an unsterile syringe (AOR, 0.95). In districts with no baseline syringe access, higher arrest rates were associated with increased odds of frequently injecting with an unsterile syringe (AOR, 1.02) When both interventions were present, arrest rates eroded the protective effects of spatial access to syringes. Spatial access to syringes in small geographic areas appears to reduce the odds of injecting with an unsterile syringe among local injectors, and arrest rates elevate these odds. Policies and practices that curtail syringe flow in geographic areas (e.g., restrictions on SEP locations or syringe distribution) or that make it difficult for injectors to use the sterile syringes they have acquired may damage local injectors' efforts to reduce HIV transmission and other injection-related harms.

Abstract
BACKGROUND Measuring syringe availability and coverage is essential in the assessment of HIV/AIDS risk reduction policies. Estimates of syringe availability and coverage were produced for the years 1996 and 2006, based on all relevant available national-level aggregated data from published sources. METHODS We defined availability as the total monthly number of syringes provided by harm reduction system divided by the estimated number of injecting drug users (IDU), and defined coverage as the proportion of injections performed with a new syringe, at national level (total supply over total demand). Estimates of supply of syringes were derived from the national monitoring system, including needle and syringe programmes (NSP), pharmacies, and medically prescribed heroin programmes. Estimates of syringe demand were based on the number of injections performed by IDU derived from surveys of low threshold facilities for drug users (LTF) with NSP combined with the number of IDU. This number was estimated by two methods combining estimates of heroin users (multiple estimation method) and (a) the number of IDU in methadone treatment (MT) (non-injectors) or (b) the proportion of injectors amongst LTF attendees. Central estimates and ranges were obtained for availability and coverage. RESULTS The estimated number of IDU decreased markedly according to both methods. The MT-based method (from 14,818 to 4809) showed a much greater decrease and smaller size of the IDU population compared to the LTF-based method (from 24,510 to 12,320). Availability and coverage estimates are higher with the MT-based method. For 1996, central estimates of syringe availability were 30.5 and 18.4 per IDU per month; for 2006, they were 76.5 and 29.9. There were 4 central estimates of coverage. For 1996 they ranged from 24.3% to 43.3%, and for 2006, from 50.5% to 134.3%. CONCLUSION Although 2006 estimates overlap 1996 estimates, the results suggest a shift to improved syringe availability and coverage over time.

Abstract
OBJECTIVE To determine the experiences, practices, and challenges associated with nonprescription syringe sales (NPSS) among pharmacists whose pharmacies were enrolled in the Disease Prevention Demonstration Project in San Francisco, CA. METHODS Self-administered survey mailed to 69 pharmacies and interviews with pharmacists and technicians. RESULTS A total of 55 of 69 pharmacies (80%) returned the survey, and eight pharmacy managers and three pharmacy technicians were interviewed in person. Of pharmacists, 72% reported none or very few problems with NPSS in the previous year, although surveys and interviews illustrated challenges associated with NPSS in terms of time management, educating patients about syringe disposal, and understanding patient preferences for syringes. Of pharmacists, 62% reported NPSS to no more than 10 to 20 patients per week and 67% collected more than 400 syringes in the previous year. One-third of pharmacists perceived that their pharmacies were located in areas where drug activity was high and that the majority of NPSS patients injected illegal drugs. CONCLUSION Access to sterile syringes is a prominent public health issue, and pharmacists can play an important role in injection drug user (IDU) education and disease prevention. This evaluation suggests that pharmacies are selling nonprescription syringes to individuals perceived to be IDUs with no major problems. Additional evaluations from health department programs are needed to demonstrate the efficacy of NPSS in California.

Abstract
Opioid-involved overdose deaths are on the rise, both nationwide and in the state of Washington. In a survey of 443 participants at syringe exchanges in Seattle, Washington, 16% had overdosed in the last year. Several factors were significantly associated in bivariate analysis: lack of permanent housing; incarceration of five or more days in the past year; gender of sex partners; sharing of syringes and other injection paraphernalia; use of speedballs (cocaine and heroin together), goofballs (methamphetamine and heroin together), buprenorphine; injection use of crack cocaine and sedatives; and use of opioids with sedatives. Adjusting for other variables in multivariate logistic regression analyses, only recent incarceration and sharing of injection materials were still significantly associated with overdose. Correctional facilities, syringe exchange programs, and other agencies serving opioid injectors should include overdose prevention components in release planning and services.

Abstract
Sterile syringe access is an important means to reduce HIV risk, but many injection drug users (IDU) who obtain syringes from sterile sources continue to share syringes. We examined the factors associated with continuing syringe sharing in New York City. We recruited 500 active IDU in 2005 through respondent-driven sampling. In multiple logistic regression, not obtaining all syringes in the past year exclusively from sterile sources was associated with increased syringe sharing. Ensuring adequate syringe availability as well as engaging and retaining nonusers and inconsistent users in sterile syringe services may increase sterile syringe access and decrease syringe sharing.

Abstract
To provide a national-scale picture of the needle exchange program in Taiwan, this study examined (a) needle and syringe program (NSP) service providers' AIDS-relevant harm reduction knowledge and attitudes; and (b) NSP services schemes and operation barriers encountered by different service modalities. A self-administrated questionnaire was mailed to all participating NSP service providers in Taiwan. A total of 414 service providers completed the postal survey. This study confirms that NSP service providers play an essential role in providing comprehensive activities to reduce HIV/AIDS infection for drug misusers. Knowledge and attitudes of service providers were found to be independently and important predictors of NSP service provisions. Community-based and clinical-based providers had diverse service schemes and encountered operation problems due to different organization characteristics, professional training, and ethical concern. For the future planning of NSP programs, service-specific education and professional support are essential component of service delivery and quality.

Abstract
Injecting use of heroin has been the highest risk substance use behavior for HIV since the beginning of the pandemic. These risks extend beyond individual levels to networks of drugs users and to wider social contexts that have been referred to collectively as the risk environment. Investigations of individual, network, and risk environment level associations with heroin availability, use, and subsequent spread among injecting drug users (IDUs) have been conducted in multiple settings, but much less is known about the world's center of illicit opium production and heroin exports-Afghanistan. Recent outbreaks of injecting drug use and of HIV infection attributed to IDUs in several African countries suggest that heroin use is expanding into new regions. This article explores the epidemiology of HIV among drug users in several risk environments, the epidemiology of heroin and its associations with HIV outbreaks among IDUs in Central Asia and the Commonwealth of Independent States, and the drug use and IDUs outbreaks now emerging in Africa. The dearth of targeted, evidence-and human rights-based responses to these epidemics is explored as a structural driver of HIV spread in these settings.

Prevalence and predictors of transitions to and away from syringe exchange use over time in 3 US cities with varied syringe dispensing policies. Drug Alcohol Depend 2010; 111:74-81.

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
Increased options for syringe acquisition and disposal have been associated with reductions in high-risk behaviors. This study determined the extent of pharmacy uptake in accessing syringes among injection drug users (IDUs) and estimated associations between pharmacy uptake and safer injection/disposal practices. Two years after the implementation of California's Disease Prevention Demonstration Project, which removed restrictions to non-prescription syringe sales through pharmacies with local authorization, IDUs were recruited through street outreach in San Francisco and interviewed regarding recent syringe acquisition, use, and disposal. The sample of 105 persons included a high proportion of men (67%), people of color (49%), and homeless persons (71%). The most common syringe source was a syringe exchange program (SEP) (80%), with pharmacies being accessed by 39% of respondents. The most commonly cited source of disposal was a SEP (65%), with very few reports of pharmacy disposal (2%). Adjusted analysis showed that unsuccessful attempts to purchase syringes at a pharmacy increased the odds of both injecting with a used syringe and giving away a used syringe. Using a SEP decreased the odds of unsafe injection and disposal practices. Thus, 2 years after the initiation of the California Disease Prevention Demonstration Project, results from this small study suggest that SEPs still provide the majority of syringe distribution and disposal services to San Francisco IDUs; however, pharmacies now augment syringe access. In addition, unsafe injection behavior is reported more often among those who do not use these syringe sources. These results are consistent with prior studies in suggesting that increasing the availability of syringes through SEPs and pharmacies, and developing bridges between them, may further reduce syringe-related risk.

Abstract
To redress gaps in injection drug users' (IDUs) knowledge about hepatitis risk and prevention, we developed a brief intervention to be delivered to IDUs at syringe exchange programs (SEPs) in three US cities. Following a month-long campaign in which intervention packets containing novel injection hygiene supplies and written materials were distributed to every client at each visit, intervention effectiveness was evaluated by comparing exposed and unexposed participants' self-reported injection practices. Over one-quarter of the exposed group began using the novel hygiene supplies which included an absorbent pad ("Safety Square") to stanch blood flow post-injection. Compared to those unexposed to the intervention, a smaller but still substantial number of exposed participants continued to inappropriately use alcohol pads post-injection despite exposure to written messages to the contrary (22.8% vs. 30.0%). It should also be noted that for those exposed to the intervention, 8% may have misused Safety Squares as part of pre-injection preparation of their injection site; attention should be paid to providing explicit and accurate instruction on the use of any health promotion materials being distributed. While this study indicates that passive introduction of risk reduction materials in injection drug users through syringe exchange programs can be an economical and relatively simple method of changing behaviors, discussions with SEP clients regarding explicit instructions about injection hygiene and appropriate use of novel risk reduction materials is also needed in order to optimize the potential for adoption of health promotion behaviors. The study results suggest that SEP staff should provide their clients with brief, frequent verbal reminders about the appropriate use when distributing risk reduction materials. Issues related to format and language of written materials are discussed.

Abstract
This study represents the first attempt in the USA to survey pharmacy nonprescription syringe customers at their point of purchase. We surveyed 62 individuals purchasing nonprescription syringes in seven pharmacies located in NYC and Albany, NY, USA. Three quarters of respondents purchased for illicit use, and 36% purchased for medical use, with differences found by race and gender. Half got their syringes from pharmacies "most of the time." Half had ever been refused a syringe purchase in a NYS pharmacy, with men, Blacks, and Hispanics reporting higher levels of refusals than women or whites. Two thirds reported syringe reuse but very few reported sharing. While approximately one quarter safely obtained and disposed of syringes "most of the time," two thirds used both safe and unsafe methods. Pharmacy-based syringe access programs are essential in areas not served by syringe exchanges.

Abstract
The HIV epidemic in China and Vietnam is on the increase among injection drug users (IDUs). We report on the results of a pilot outreach study in northern Vietnam and southern China to test the feasibility of a peer-driven intervention (PDI) to prevent HIV among IDUs. In the PDI, recruitment relies on a “chain-referral” model in which IDUs carry-out the core outreach activities that salaried outreach-workers/peer-educators traditionally provide. A 6-month follow-up was built into the study design to measure possible changes in IDUs' risk behaviors. The impact results of the pilot study are reported bearing on several different measures, such as changes in IDUs' rates of lending or borrowing used syringes, willingness to enter into drug treatment, baseline and follow-up recruitment success, and effectiveness of serving as peer-educators in the community. The evidence suggests the PDI is highly feasible and deserving of greater research in both China and Vietnam.

Abstract
BACKGROUND Programmatic data from New York City syringe exchange programs suggest that many clients visit the programs infrequently and take few syringes per transaction, while separate survey data from individuals using these programs indicate that frequent injecting - at least daily - is common. Together, these data suggest a possible "syringe gap" between the number of injections performed by users and the number of syringes they are receiving from programs for those injections. METHODS We surveyed a convenience sample of 478 injecting drug users in New York City at syringe exchange programs to determine whether program syringe coverage was adequate to support safer injecting practices in this group. RESULTS Respondents reported injecting a median of 60 times per month, visiting the syringe exchange program a median of 4 times per month, and obtaining a median of 10 syringes per transaction; more than one in four reported reusing syringes. Fifty-four percent of participants reported receiving fewer syringes than their number of injections per month. Receiving an inadequate number of syringes was more frequently reported by younger and homeless injectors, and by those who reported public injecting in the past month. CONCLUSION To improve syringe coverage and reduce syringe sharing, programs should target younger and homeless drug users, adopt non-restrictive syringe uptake policies, and establish better relationships with law enforcement and homeless services. The potential for safe injecting facilities should be explored, to address the prevalence of public injecting and resolve the 'syringe gap' for injecting drug users.

Abstract
This research presents estimates of HIV prevalence rates among injection drug users (IDUs) in large US metropolitan statistical areas (MSAs) during 1992-2002. Trend data on HIV prevalence rates in geographic areas over time are important for research on determinants of changes in HIV among IDUs. Such data also provide a foundation for the design and implementation of structural interventions for preventing the spread of HIV among IDUs. Our estimates of HIV prevalence rates among IDUs in 96 US MSAs during 1992-2002 are derived from four independent sets of data: (1) research-based HIV prevalence rate estimates; (2) Centers for Disease Control and Prevention Voluntary HIV Counseling and Testing data (CDC CTS); (3) data on the number of people living with AIDS compiled by the CDC (PLWAs); and (4) estimates of HIV prevalence in the US. From these, we calculated two independent sets of estimates: (1) calculating CTS-based Method (CBM) using regression adjustments to CDC CTS; and (2) calculating the PLWA-based Method (PBM) by taking the ratio of the number of injectors living with HIV to the numbers of injectors living in the MSA. We take the mean of CBM and PBM to calculate over all HIV prevalence rates for 1992-2002. We evaluated trends in IDU HIV prevalence rates by calculating estimated annual percentage changes (EAPCs) for each MSA. During 1992-2002, HIV prevalence rates declined in 85 (88.5%) of the 96 MSAs, with EAPCs ranging from -12.9% to -2.1% (mean EAPC=-6.5%; p<0.01). Across the 96 MSAs, collectively, the annual mean HIV prevalence rate declined from 11.2% in 1992 to 6.2 in 2002 (EAPC, -6.4%; p<0.01). Similarly, the median HIV prevalence rate declined from 8.1% to 4.4% (EAPC, -6.5%; p<0.01). The maximum HIV prevalence rate across the 11 years declined from 43.5% to 22.8% (EAPC, -6.7%; p<0.01). Declining HIV prevalence rates may reflect high continuing mortality among infected IDUs, as well as primary HIV prevention for non-infected IDUs and self-protection efforts by them. These results warrant further research into the population dynamics of disease progression, access to health services, and the effects of HIV prevention interventions for IDUs.

Abstract
Although considerable research has been conducted to identify the behavioural characteristics that predispose individuals to inject drugs or become infected with HIV via injection drug use, much less research has been conducted on structural and policy determinants, cultural norms, stigma, and ecological factors which may affect drug use risk behaviour, users' networks and HIV rates associated with drug use across geographic areas. For programme planners, whether official or grassroots, an understanding of place-based characteristics can help better identify risk environments to injection drug use-related HIV, and determine how to facilitate actions regarding public policy and harm reduction to aid in the reduction of risk. As such, we consider in this commentary the importance of geographic place and the socio-spatial and political processes related to place that may help determine where IDU-related HIV risk environments occur.

Abstract
AIM To develop the Treatment Outcomes Profile (TOP), a new instrument for monitoring substance misuse treatment. DESIGN Prospective cohort, psychometric evaluation with 7-day retest and 1-month follow-up to assess inter-rater reliability, concurrent, discriminant and construct validity, and change sensitivity. PARTICIPANTS A sample of 1021 service users, aged 16-62 years. Recruitment from 63 treatment agencies in England, collectively providing opioid substitution treatment, psychosocial interventions, in-patient detoxification and residential rehabilitation. MEASUREMENTS Thirty-eight frequency, rating scale and period prevalence measures, with 28-day recall, across substance use, health, crime and social functioning domains, administered as personal interview by 163 treatment keyworkers. FINDINGS Twenty outcome measures met inter-rater reliability criteria: days used alcohol, opioids, crack cocaine, cocaine powder, amphetamines, cannabis and one other named substance; days injected and period prevalence of direct or indirect needle/syringe sharing; subjective rating of physical and psychological health; days committed shop theft and drug selling, period prevalence of vehicle, property, fraud/forgery and assault/violence offences; rating of quality of life; days worked and attended for education/training; and period prevalence of acute housing problems and risk of eviction. Intraclass correlation coefficients for scale measures and Cohen's kappa for dichotomous measures reached or exceeded 0.75 and 0.61, respectively. There were satisfactory validity assessments and change sensitivity of scale items judged by effect size and smallest detectable difference. The TOP clinical tool contains an additional 10 items for individual treatment planning and review. CONCLUSIONS The TOP is a reliable and valid 20-item instrument for treatment outcomes monitoring.

Abstract
OBJECTIVES We used cluster analysis to subdivide a population of injection drug users and identify previously unknown behavioral heterogeneity within that population. METHODS We applied cluster analysis techniques to data collected in a cross-sectional survey of injection drug users in Winnipeg, Manitoba. The clustering variables we used were based on receptive syringe sharing, ethnicity, and types of drugs injected. RESULTS Seven clusters were identified for both male and female injection drug users. Some relationships previously revealed in our study setting, such as the known relationship between Talwin (pentazocine) and Ritalin (methylphenidate) use, injection in hotels, and hepatitis C virus prevalence, were confirmed through our cluster analysis approach. Also, relationships between drug use and infection risk not previously observed in our study setting were identified, an example being a cluster of female crystal methamphetamine users who exhibited high-risk behaviors but an absence or low prevalence of blood-borne pathogens. CONCLUSIONS Cluster analysis was useful in both confirming relationships previously identified and identifying new ones relevant to public health research and interventions.

Greater drug injecting risk for HIV, HBV, and HCV infection in a city where syringe exchange and pharmacy syringe distribution are illegal. J Urban Health 2008; 85:309-22. [PMID: 18340537 PMCID: PMC2329750 DOI: 10.1007/s11524-008-9271-1] [Citation(s) in RCA: 39] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2007] [Accepted: 02/26/2008] [Indexed: 10/22/2022]
Abstract
Comparing drug-injecting risk between cities that differ in the legality of sterile syringe distribution for injection drug use provides a natural experiment to assess the efficacy of legalizing sterile syringe distribution as a structural intervention to prevent human immunodeficiency virus (HIV) and other parenterally transmitted infections among injection drug users (IDUs). This study compares the parenteral risk for HIV and hepatitis B (HBV) and C (HCV) infection among IDUs in Newark, NJ, USA, where syringe distribution programs were illegal during the period when data were collected, and New York City (NYC) where they were legal. IDUs were nontreatment recruited, 2004-2006, serotested, and interviewed about syringe sources and injecting risk behaviors (prior 30 days). In multivariate logistic regression, adjusted odds ratios (AOR) and 95% confidence intervals (95% CI) for city differences are estimated controlling for potential city confounders. IDUs in Newark (n = 214) vs. NYC (n = 312) were more likely to test seropositive for HIV (26% vs. 5%; AOR = 3.2; 95% CI = 1.6, 6.1), antibody to the HBV core antigen (70% vs. 27%; AOR = 4.4; 95% CI = 2.8, 6.9), and antibody to HCV (82% vs. 53%; AOR = 3.0; 95% CI = 1.8, 4.9), were less likely to obtain syringes from syringe exchange programs or pharmacies (AOR = 0.004; 95% CI = 0.001, 0.01), and were more likely to obtain syringes from street sellers (AOR = 74.0; 95% CI = 29.9, 183.2), to inject with another IDU's used syringe (AOR = 2.3; 95% CI = 1.1, 5.0), to reuse syringes (AOR = 2.99; 95% CI = 1.63, 5.50), and to not always inject once only with a new, sterile syringe that had been sealed in a wrapper (AOR = 5.4; 95% CI = 2.9, 10.3). In localities where sterile syringe distribution is illegal, IDUs are more likely to obtain syringes from unsafe sources and to engage in injecting risk behaviors. Legalizing and rapidly implementing sterile syringe distribution programs are critical for reducing parenterally transmitted HIV, HBV, and HCV among IDUs.

Abstract
BACKGROUND Evaluations of syringe-exchange programme effectiveness that attempt to measure "coverage" by determining the percentage of the at-risk population reached by a programme are insufficient since programmes must provide syringes on a continual basis. Determining the relationship between the extent of programme coverage and its impact (i.e., reductions in disease risk or incidence) is complicated by the lack of controlled trials with cohorts of drug users and instead has to be estimated by imputation, mathematical modelling, or ecological data analysis. This report offers an approach to determine community-wide impact and discusses the limitations of that approach. METHODS Easily created programme tracking data were maintained by exchanges in New Haven, CT, USA and Chicago, IL, USA. Data compiled by month quantified the number of unique participants visiting syringe-exchange programmes and the number of syringes distributed. "Coverage", defined either as the percentage of individuals reached or percentage of community syringe need met, was estimated by incorporating measures of the size of the injector population or injection frequency. These measures of coverage are placed in the context of changing programme operations to estimate the effect of these changes on coverage. Finally, data on AIDS cases from New Haven and Chicago were used to estimate the community-wide impact of syringe exchange. RESULTS Two mobile syringe-exchange programmes operated with very different exchange policies. Programme data revealed that coverage of individuals rarely exceeded 10% and was higher in New Haven than in Chicago. On the other hand, coverage measured as the percentage of syringe need met was higher at the Chicago exchange that employed the less restrictive policy. The impact of syringe exchange in the two cities was measured by comparing subsequent AIDS cases. The relative reduction in injection-related AIDS cases as a function of all new AIDS diagnoses was 21.7% in New Haven and 41.4% in Chicago. CONCLUSIONS A modest investment in the collection of programme data can yield reliable and interpretable information on the extent of programme reach and retention. Limitations to the approach result from the ecological nature of the data and from the need to use data from outside the programme that may be less reliable. For the cases presented here, coverage rates will vary as a function of the programme policies; however, even modest coverage rates - well below those recommended by UNAIDS - can have significant impacts on HIV epidemics. Restrictive policies appeared to increase the coverage if measured only by the proportion of monthly participants and not by the proportion of syringe need met by a programme. More generally, programmes can collect programmatic data and some rapid assessment data (estimates of IDU population and injection frequency) to estimate of the impact of their programmes.

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
OBJECTIVES This study examined risk factors for receptive syringe sharing (RSS) during illicit drug injection by persons 15-30 years old in five U.S. cities. METHODS Participants were recruited through street outreach and respondent-driven referrals in Baltimore, Chicago, Los Angeles, New York, and Seattle between May 2002 and January 2004. Surveys of drug use, sexual behaviors, and correlates were administered through audio computer-assisted self-interviews at baseline and, for the subset of participants who enrolled in an HIV/HCV prevention intervention trial, at 3-months and 6-months post-baseline. The proportions of injections involving RSS at baseline and at follow-up were used as outcomes in multivariate models that adjusted for intervention effects. RESULTS At baseline, 54% of 3128 participants reported RSS in the past 3 months. RSS decreased to 21% at 6-months post-baseline for the combined trial arms. Participants were more likely to report RSS if they perceived that their peers were not against RSS and if they injected with sex partners. Lower levels of perceived risk of infection with HIV (baseline, p<.001) or HCV (follow-up, p<.001) through RSS were also significant predictors of greater RSS. CONCLUSIONS Perceived risks, peer influences, and type of injection partner were robust predictors of RSS. Perceived risks and peer influences are particularly amenable to intervention efforts that may prevent RSS in this age group.

Abstract
OBJECTIVE To determine if adequate syringe coverage --"one shot for one syringe"--among syringe exchange program (SEP) clients is associated with injection-related HIV risk behaviors and syringe disposal. DESIGN HIV risk assessments with 1577 injection drug users (IDUs) recruited from 24 SEPs in California between 2001 and 2003. Individual syringe coverage was calculated as a proportion of syringes retained from SEP visits to total number of injections in the last 30 days. RESULTS Participants were divided into four groups based on syringe coverage: <50%, 50-99%, 100-149%, and 150% or more. In multivariate logistic regression, SEP clients with less than 50% syringe coverage had significantly higher odds of reporting receptive syringe sharing in the last 30 days (adjusted odds ratio [AOR]=2.3; 95% confidence interval [CI]=1.4, 3.6) and those with 150% or more coverage had lower odds of reporting receptive syringe sharing (AOR=0.5; 95%CI=0.3, 0.8) as compared to SEP clients with adequate syringe coverage of 100-149%. Similar associations were observed for other main outcomes of distributive syringe sharing and syringe re-use. No differences in safe syringe disposal were observed by syringe coverage. CONCLUSIONS Individual syringe coverage is strongly associated with safer injection behaviors without impacting syringe disposal among SEP clients. Syringe coverage is a useful measure for determining if IDUs are obtaining sufficient syringes to lower HIV risk.

Abstract
OBJECTIVES We studied the effect of local approval of syringe exchange programs in California (through Assembly AB136) on program availability and performance. METHODS We determined the number of active syringe exchange programs in California by conducting Internet searches and obtaining information from the state and from local programs. To track changes in program availability and performance between 2000 and 2002, we interviewed 24 program directors annually for 3 years about program characteristics, syringe exchange policies, law enforcement contact, and other issues. We conducted multivariate analyses to determine whether AB136 approval status was associated with changes in performance. RESULTS Fifteen local governments (13 counties and 2 cities) enacted the new law by 2002, and operating syringe exchange programs increased from 24 to 35. The proportion of these programs that were not locally approved declined from 54% to 40%. No new approved programs were started in high-need counties. Total syringes exchanged increased by more than 1 million per year, average annual budgets increased by more than 50%, and police harassment of the program volunteers, clients, and operators declined. Improvements at approved syringe exchange programs accounted for these changes. CONCLUSIONS Statewide approval and funding appears necessary to further syringe exchange availability in California.

Abstract
Legislation passed in 2000 allowed syringe exchange programs (SEPs) in California to operate legally if local jurisdictions declare a local HIV public health emergency. Nonetheless, even in locales where SEPs are legal, the possession of drug paraphernalia, including syringes, remained illegal. The objective of this paper is to examine the association between the legal status of SEPs and individual arrest or citation for drug paraphernalia among injection drug users (IDUs) in California from 2001 to 2003. Using data from three annual cross-sections (2001-03) of IDUs attending 24 SEPs in 16 California counties (N = 1,578), we found that overall, 14% of IDUs in our sample reported arrest or citation for paraphernalia in the 6 months before the interview. Further analysis found that 17% of IDUs attending a legal SEP (defined at the county level) reported arrest or citation for drug paraphernalia compared to 10% of IDUs attending an illegal SEP (p = 0.001). In multivariate analysis, the adjusted odds ratio of arrest or citation for drug paraphernalia was 1.6 [95% confidence interval (CI) = 1.2, 2.3] for IDUs attending legal SEPs compared to IDUs attending illegal SEPs, after controlling for race/ethnicity, age, homelessness, illegal income, injection of amphetamines, years of injection drug use, frequency of SEP use, and number of needles received at last visit. IDUs attending SEPs with legal status may be more visible to police, and hence, more subject to arrest or citation for paraphernalia. These findings suggest that legislative efforts to decriminalize the operation of SEPs without concurrent decriminalization of syringe possession may result in higher odds of arrest among SEP clients, with potentially deleterious implications for the health and well-being of IDUs. More comprehensive approaches to removing barriers to accessing sterile syringes are needed if our public health goals for reducing new HIV/HCV infections are to be obtained.

Abstract
AIM To determine whether syringe exchange programs' (SEPs) dispensation policy is associated with syringe coverage among SEP clients. DESIGN Cross-sectional samples of SEPs and their clients. SETTING SEPs in California, USA. PARTICIPANTS Twenty-four SEPs and their injection drug using (IDU) clients (n = 1576). MEASUREMENTS Clients were classified as having adequate syringe coverage if they received at least as many syringes from the SEP as their self-reported injections in the last 30 days. SEPs were classified based on their syringe dispensation policy. Dispensation schemes ranging from least restrictive to most are: unlimited needs-based distribution; unlimited one-for-one exchange plus a few additional syringes; per visit limited one-for-one plus a few additional syringes; unlimited one-for-one exchange; and per visit limited one-for-one exchange. FINDINGS Adequate syringe coverage among SEP clients by dispensation policy is as follows: unlimited needs-based distribution = 61%; unlimited one-for-one plus = 50%; limited one-for-one plus = 41%; unlimited one-for-one = 42%; and limited one-for-one = 26%. In multivariate analysis, adequate syringe coverage was significantly higher for all dispensation policies compared to per visit limited one-for-one exchange. Using propensity scoring methods, we compared syringe coverage by dispensation policies while controlling for client-level differences. Providing additional syringes above one-for-one exchange (50% versus 38%, P = 0.009) and unlimited exchange (42% versus 27%, P = 0.05) generally resulted in more clients having adequate syringe coverage compared to one-for-one exchange and per visit limits. CONCLUSION Providing less restrictive syringe dispensation is associated with increased prevalence of adequate syringe coverage among clients. SEPs should adopt syringe dispensation policies that provide IDUs sufficient syringes to attain adequate syringe coverage.

Abstract
Ketamine, a dissociative anesthetic, has emerged as an increasingly common drug among subgroups of young injection drug users (IDUs) in cities across the United States. In-depth qualitative interviews were conducted with 213 young IDUs aged 16-28 years recruited in New York, New Orleans, and Los Angeles between 2004 and 2006. While some initiated injection drug use with ketamine, the drug was more frequently injected by IDUs with extensive polydrug using histories. IDUs initiating with ketamine commonly self-injected via an intramuscular mode of administration. The injection group provided crucial knowledge and material resources that enabled the injection event to occur, including ketamine, syringes, and injection skills. Injection paraphernalia was commonly shared during the first injection of ketamine, particularly vials of pharmaceutically-packaged liquid ketamine. Injection events infrequently occurred in a rave or club and more typically in a private home, which challenges ketamine's designation as a 'club' drug. The first injection of ketamine was a noteworthy event since it introduced a novel drug or new mode of administration to be further explored by some, or exposed others to a drug to be avoided in the future. Risk reduction messages directed towards young IDUs should be expanded to include ketamine.
