Abstract
We conducted a systematic review and meta-analysis of the impact of needle and syringe exchange programs (NSP) on both individual- and community-level needle-sharing behaviors and other HIV-related outcomes in low- and middle-income countries (LMIC). A search of five databases for peer-reviewed trial or quasi-experimental studies reported through July 2021 identified 42 interventions delivered in 35 studies, with a total of 56,751 participants meeting inclusion criteria. Random-effects meta-analysis showed a significant protective association between NSP exposure and needle-sharing behaviors at the individual-level (odds ratio [OR] = 0.25, 95% confidence interval [CI] = 0.16-0.39, 8 trials, n = 3947) and community-level (OR 0.39, CI 0.22-0.69, 12 trials, n = 6850), although with significant heterogeneity. When stratified by needle-sharing directionality, NSP exposure remained associated with reduced receptive sharing, but not distributive sharing. NSP exposure was also associated with reduced HIV incidence and increased HIV testing but there were no consistent associations with prevalence of bloodborne infections. Current evidence suggests positive impacts of NSPs in LMICs.

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

Abstract
BackgroundOpioid use has reached epidemic proportions in rural communities in the United States and injection of drugs is commonly used. As a result of shared or reusing needles and syringes, the risk for contracting blood-borne diseases is significantly increased. Rural areas face many social and attitudinal barriers regarding syringe exchange programs (SEPs).ObjectiveThis article describes national trends for drug injection problems in rural areas and discusses effectiveness of needle and SEPs as a harm reduction healthcare policy. Ethical and practical considerations in the implementation of SEPs are also presented.MethodThe rehabilitation literature was reviewed on trends in substance abuse and intravenous (IV) drug use in rural areas to identify the status and need for SEPs to address risk factors of infectious diseases resulting from needle sharing and reusing of needles.FindingsIV drug use in rural communities has reached epidemic proportions with resulting dramatic increases in hepatitis C and B and incidence of HIV. Yet, many rural communities continue to object to the implementation of SEPs due to fears that such programs will increase drug use and crime in the community.ConclusionIV drug use is a critical public health issue for users and non-IV users in rural communities, and is increasingly becoming an issue about which rural rehabilitation counselors will need to be informed. For the sake of public health, SEPs should be recognized as an economical, ethical, and effective factor in the larger response to the epidemic of IV drug use in rural America.

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

Abstract
This study funded by Centers for Disease Control compares HIV prevalence and risk behavior among heterosexual methamphetamine (n = 428) and nonmethamphetamine (n = 878) injectors in California, USA, during 2001-2003. While HIV was not highly prevalent among methamphetamine injectors (3%), sexual and injection risk behaviors were highly prevalent (ranging from 21% to 72%). In multivariate analyses, methamphetamine injectors had higher odds than nonmethamphetamine injectors of unprotected vaginal intercourse and sex with five or more sexual partners in the past 6 months and of distributive and receptive syringe sharing in the past 30 days. There was no significant difference in HIV sero-status by methamphetamine use. Suggestions are made for designing HIV prevention programs. The study's limitations are noted.

Abstract
This study examined the effect of syringe exchange program setting on the injection practices, health status, and health service utilization patterns of injection drug users (IDUs) recruited from a public urban hospital. One hundred sixty-six participants were randomized to either community- or hospital-based syringe exchange services. Poisson regression models were used to compare service utilization between groups. In both conditions, risky drug use practices decreased, and physical health functioning improved over time. Hospital-based syringe exchange program (SEP) attendees had 83% more inpatient admissions (p < .0001) and 22% more ambulatory care visits (p < .0001) than those assigned to the community-based SEP condition. Syringe exchange services that are integrated into public hospital settings may serve as a valuable strategy to engage hard to reach IDU populations in behavioral interventions designed to reduce HIV risk transmission behaviors and increase access to, or engagement in, the use of secondary and tertiary preventive medical care.

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
The concept of coverage first emerged in the 1960s as a key indicator for measuring the proportion of populations that were covered by health care. In the area of HIV interventions among injecting drug users, the term "coverage" has been used for widely different aspects of reach and effectiveness of programmes. This paper reviews an array of ways of thinking about coverage from the scientific and grey literature and discusses methods of estimating coverage, finding that some measures of coverage refer to individuals, others to populations and others to populations covered by services. Nomenclature for these various types of "coverage" are discussed and recommendations are provided for future attempts to measure coverage of harm reduction interventions.

Abstract
While there have been numerous papers published in the medical, social, and epidemiologic literature about the effectiveness of syringe exchange programs (SEPs), few papers identify operational characteristics of the SEPs they study or assess which of those characteristics are associated with optimal HIV risk reduction among clients. The objective of this study was to examine whether different syringe dispensation policies were associated with client-level injection-related HIV risk. Injection drug users (IDUs) were recruited at 23 SEPs in California in 2001 (n = 531). SEPs were classified by their executive directors as to whether they provided a strict one-for-one syringe exchange, gave a few extra syringes above the one-for-one exchange, or distributed the amount of syringes based upon need as opposed to how many syringes were turned in by the clients. Injection-related risk was compared by SEP program type. In multivariate logistic regression analysis, clients of distribution-based programs had lower odds of reusing syringes (adjusted odds ratio = 0.43; 95% CI = 0.27, 0.71) when adjusting for confounding variables. There were no statistical differences with regards to distributive or receptive syringe sharing by dispensation policy. It is concluded that SEPs that base syringe dispensation policy upon need may facilitate reductions in reuse of syringes.

Abstract
AIM Better sterile syringe access should be associated with a lower likelihood of syringe re-use and receptive syringe sharing, although few empirical studies have examined gradients in syringe access using both individual and ecological data. In this study, we compare syringe re-use and receptive syringe sharing among injection drug users (IDUs) with syringe exchange program (SEP) and legal over-the-counter pharmacy access with limits on syringes that can be purchased, exchanged or possessed to IDUs with no pharmacy sales but unlimited syringe access through SEPs. We address three questions: (1) Does residing in an area with no legal syringe possession increase the likelihood of police contact related to possessing drug paraphernalia? (2) Among direct SEP users, is use of more permissive SEPs associated with less likelihood of syringe re-use and receptive syringe sharing? (3) Among non-SEP users, is residing in an area with pharmacy access associated with lower likelihood of syringe re-use and receptive syringe sharing? DESIGN Quantitative survey of IDUs recruited from SEPs, subject nomination and outreach methods. Multivariate analyses compared police contact, syringe re-use and receptive syringe sharing among IDUs recruited in three cities. FINDINGS In multivariate analyses, we found that police contact was associated independently with residing in the area with no legal possession of syringes; among SEP users, those with access to SEPs without limits had lower syringe re-use but not lower syringe sharing; and that among non-SEP users, no significant differences in injection risk were observed among IDUs with and without pharmacy access to syringes. CONCLUSION We found that greater legal access to syringes, if accompanied by limits on the number of syringes that can be exchanged, purchased and possessed, may not have the intended impacts on injection-related infectious disease risk among IDUs.
