Street-level policing in the Downtown Eastside of Vancouver, Canada, during the 2010 Winter Olympics

BackgroundPolice presence within street-based drug scenes has the potential to disrupt injection drug users’ (IDUs) access to health services and prompt increased injection-related risk behaviour. We examined street-level policing in the Downtown Eastside (DTES) of Vancouver during the Olympic Winter games, to assess the potential impact on access to harm reduction services and injection-related risk behaviour.MethodsWe analysed data from observational activities documenting police and drug user behaviour, unstructured interviews with drug users in street settings (n = 15), expert interviews with legal and health professionals (n = 6), as well as utilisation statistics from a local supervised injection facility (SIF).ResultsAlthough police presence was elevated within the DTES during the Olympics, there was little evidence to suggest that police activities influenced IDUs’ access to health services or injection-related risk behaviour. SIF attendance during the Olympics was consistent with regular monthly patterns.ConclusionPolice presence during the Olympics did not reduce access to health services amongst local IDUs or prompt increased injection-related risk behaviour. Increased cooperation between local law enforcement and public health bodies likely offset the potential for negative health consequences resulting from police activity.     

Public Health Interventionists,Penny Capitalists,or Sources of Risk?: Assessing Street Syringe Sellers in Hartford,Connecticut

Improved access to sterile syringes decreases risks related to blood-borne transmission of HIV and hepatitis among injection drug users (IDUs). While syringe exchange programs and pharmacy sales of over-the-counter syringes have received considerable attention from researchers and interventionists during the past decade, little is known about informal economy street syringe sellers. In Hartford, CT, as well as other regions throughout the United States a large percentage of IDUs utilize street sellers to facilitate their injection activities. A qualitative and ethnographic study was conducted in Hartford between 1999 and 2001 to help elucidate the public health risks and benefits of street syringe sellers.

Survival of Human Immunodeficiency Virus Type 1 After Rinsing Injection Syringes with Different Cleaning Solutions

Bleaching of syringes has been advocated to prevent HIV transmission among injection drug users (IDUs). Several reports indicate that IDUs use household products to disinfect syringes instead of bleach. To test their disinfection efficacy, we performed syringe-rinsing simulations with a range of agents used by IDUs trying to disinfect their syringes. No viable HIV-1 was recovered from syringes rinsed with bleach diluted 1 : 10. Bleach stored at 37°C and rubbing alcohol performed better than water and the other liquids tested, but less well than bleach 1 : 10. Rinsing syringes with the other liquids was similar to rinsing with water alone. Increasing the rinsing volume did not always increase the effect of rinsing, but the addition of a second rinse consistently increased rinsing efficacy. Bleaching remains the most effective disinfectant among those tested. It is important that IDUs learn the proper techniques for bleach storage and syringe decontamination. Other household products are not effective disinfectants and should be avoided. Because access to sterile syringes may be restricted by laws, public policy, and police practices, bleach retains its importance in the control of the HIV-1 epidemic among IDUs.

Practices surrounding syringe acquisition and disposal: effects of Syringe Exchange Programmes from different Brazilian regions—the AjUDE-Brasil II Project

The study describes practices relating to syringe acquisition and disposal by Syringe Exchange Programme (SEP) participants. A cross-sectional multi-city study enrolled 857 injection drug users (IDUs) from six SEPs in different Brazilian regions, and assessed self-reported acquisition and disposal behaviours. Seven hundred and nine males (82.9%) and 146 females (17.1%) were recruited through outreach and interviewed, most from the streets or their neighbourhoods (54.1%). The average age was 28.5 years; 76.4% reported injecting cocaine in the past 6 months. Sources for acquiring new syringes differed significantly between time of injection drug use debut and the 6 months prior to interview. Fifty-three percent of IDUs reported acquiring their syringes in pharmacies when they initiated injection drug use, whereas most reported acquiring new syringes in the 6 months before interview from several simultaneous sources: 69% through SEPs; 58% through pharmacies; 36% from friends and/or sexual partners; and 17% from other health services. Across SEPs, acquisition and disposal varied widely. Most interviewees discarded their syringes on the streets, in open fields, or in the garbage or sewage. Restrictions on syringe availability and unsafe practices may be functioning as barriers to the public health recommendation of one-time use of sterile syringes for IDUs and discouraging community support to SEPs. Further increase in access to legal, inexpensive and timely sterile syringes, as well as counselling about the merits of one-time use and safer disposal must be reinforced as part of efforts to minimise high-risk behaviours and curb the spread of blood-borne infections.     

Qualitative evaluation of a peer-based needle syringe programme in Vietnam

BackgroundHarm reduction has been identified as an important HIV prevention strategy for injecting drug users (IDUs) in Vietnam. However, to date only small geographically limited formal needle syringe programmes (NSPs) have been implemented; and little attention has been given to assessing the effectiveness of the piloted models. Using data from a qualitative evaluation of an NSP in northern Vietnam, this paper assesses the effectiveness of the intervention, examines barriers to the NSP, and documents lessons which can be applied to replicate and scale up interventions across Vietnam.MethodsData were gathered using key informant interviews, focus group discussions, in-depth interviews, observation and intercept interviews with IDUs and other project stakeholders. IDUs were introduced to the evaluation by peer educators (PEs).ResultsThe project contributed to a shift toward safe injecting practices and safe disposal of used needles and syringes (N&;S) among IDUs. Collection of used N&;S positively influenced community attitudes toward PEs and IDUs. Reduced community discrimination, achieved as a result of project advocacy activities, encouraged IDU to access free needle syringes and other project services provided by PEs. Resistance from the local government officials and community members was turned into support for the programme through intensive advocacy activities. The project highlighted the importance of involving law enforcement in the programme and promoted a public health approach toward working with IDU. However, periodic police campaigns against drug use continued to be an obstacle to successful programme implementation and demonstrated the need for continued efforts to address the issue.ConclusionProgramme success is dependent upon community support. Resistance to NSPs can be overcome through a programme of intensive advocacy with community stakeholders including; local government, mass organizations, local residents, IDUs and their families. Garnering the support of law enforcement officials requires a sustained effort.     

Law enforcement influences on HIV prevention for injection drug users:: Observations from a cross-border project in China and Vietnam

Law enforcement activity has had multiple influences on injection drug users’ (IDUs’) participation in a cross-border HIV prevention project in southern China and northern Vietnam. The project has successfully achieved and maintained the official support of police and other government agencies and effectively implemented its interventions. However, analysis of process data, site visit observations, and interviews with project staff, peer educators, IDUs, and police officers reveal the ongoing effects of actual and perceived threats from law enforcement, as well as community stigmatisation, on IDUs’ project participation. These effects are discernible in variations in the monthly numbers of needles/syringes provided, cross-border differences in IDUs’ preferred ways to receive new needles/syringes and retain used needles/syringes for exchange, and geographic patterns of IDUs’ receiving and redeeming pharmacy vouchers. HIV prevention programmes must not only maintain the support of police and other officials but also convince IDUs that it is both beneficial and safe for them to participate in the interventions. Programmes must also be implemented with flexibility, adapting to the potentially changeable preferences, perceptions, and needs of IDUs.     

Development and implementation of a cross-border HIV prevention intervention for injection drug users in Ning Ming County (Guangxi Province), China and Lang Son Province, Vietnam

This paper describes the background and early implementation of a peer-based HIV prevention intervention involving social marketing of sterile needles and syringes for injection drug users (IDUs) in a border region of northern Vietnam and southern China. Peer educators collect and safely dispose of used needles and syringes and provide IDUs with a choice of new needles/syringes or vouchers redeemable in pharmacies and clinics for new needles/syringes. The project arose from a pattern of changing drug use and increasing HIV infection in the region but its development took 4 years and faced many challenges. Implementation of the intervention posed a new set of challenges for the participating health departments, police, peer educators, pharmacists, injection drug users, and the communities at large. Early implementation of the project has revealed successful multi-sectoral collaboration, and broad acceptance by IDUs of pharmacy vouchers and distribution of new needles/syringes. However, IDUs’ persistent fear of the police, particularly in Vietnam, has required reliance on separate collection by peer educators of used needles/syringes and distribution of pharmacy vouchers and new needles. In China, new needles/syringes and vouchers are largely being provided through exchange. Understanding the development and implementation challenges and the strategies that were successful in overcoming them (including the importance of being flexible and adaptable to contextual factors) may be useful to those interested in launching similar, much-needed interventions in other parts of the world.     

Drug injectors and dealers in Odessa, Ukraine

This article reports on the results observed in a series of focus groups and in-depth interviews with injection drug users (IDUs) and drug dealers in Odessa, Ukraine. Ukraine has the highest rate of HIV infection in Eastern as well as Western Europe, and Odessa ranks among the cities in that country with the highest seroprevalence. The epidemic is largely concentrated among IDUs, although heterosexual transmission is increasing. The purpose of this study was to further understand the context in which HIV-related risk behaviors occur in order to recommend intervention strategies that might reduce the rate of new infections. The drug users who participated in the research were impoverished and severely addicted. Findings revealed that there were two sources for drugs in Odessa: either from gypsies in preloaded syringes, or from drug dealers also in a liquid form. The most common drug injected was liquid poppy straw, a weak opiate known as "hemia." Results showed widespread victimization of drug users by police officials, leading to increased risk-taking to avoid arrest or harassment. Needle/syringe sharing was common and users rarely had time to disinfect their works. The most common product used to clean was urine, believed to be an antiseptic. When asked to recommend prevention strategies to reduce the rising rate of HIV, the most common response by the users and dealers was to legalize drugs. The drug and HIV epidemics in Odessa, as well as all of Ukraine, call for urgent public health measures to impact and improve the health of its citizens.     

Racial differences in acquisition of syringes from pharmacies under conditions of legal but restricted sales

BackgroundInjecting drug users (IDUs) are at increased risk of acquiring and transmitting HIV and other bloodborne pathogens through the multi-person use of syringes. Although research has shown that increased access to syringes through syringe exchange programs (SEPs) is an effective strategy to reduce risky injection practices many areas of the United States still do not have SEPs. In the absence of SEPs, legislation allowing pharmacies over-the-counter sales of syringes has also been shown to reduce syringe sharing. The success of pharmacy sales however is limited by other legal stipulations, such as drug paraphernalia laws, which in turn may contribute to fear among IDUs about being caught purchasing and carrying syringes.MethodsBetween 2003 and 2006, 851 out-of-treatment IDUs were recruited using street outreach in the Raleigh-Durham (North Carolina) area. Data were collected using audio-computer assisted interview (ACASI) technology. Multiple logistic regression analyses were performed to assess factors associated with purchasing syringes from pharmacies.ResultsIn our study sample, African-American IDUs were one-fifth as likely as white IDUs to report pharmacies as their primary source of syringes.ConclusionsGiven the absence of syringe exchange programs and the relatively high prevalence of HCV and HIV among IDUs in the Raleigh-Durham area, the limited use of pharmacies as a source of syringes among African-American IDUs in this study sample is problematic. The study findings support the need for effective multilevel interventions to increase access to clean needles in this population, as well as for policy interventions, such as legalization of SEPs and elimination of penalties for carrying syringes, to reduce harm and eliminate the health threats posed by receptive syringe sharing.     

Integrating multiple programme and policy approaches to hepatitis C prevention and care for injection drug users: a comprehensive approach

BackgroundNew York State is home to an estimated 230,000 individuals chronically infected with hepatitis C virus (HCV) and roughly 171,500 active injection drug users (IDUs). HCV/HIV co-infection is common and models of service delivery that effectively meet IDUs’ needs are required. A HCV strategic plan has stressed integration.MethodsHCV prevention and care are integrated within health and human service settings, including HIV/AIDS organisations and drug treatment programmes. Other measures that support comprehensive HCV services for IDUs include reimbursement, clinical guidelines, training and HCV prevention education. Community and provider collaborations inform programme and policy development.ResultsIDUs access 5 million syringes annually through harm reduction/syringe exchange programmes (SEPs) and a statewide syringe access programme. Declines in HCV prevalence amongst IDUs in New York City coincided with improved syringe availability. New models of care successfully link IDUs at SEPs and in drug treatment to health care. Over 7000 Medicaid recipients with HCV/HIV co-infection had health care encounters related to their HCV in a 12-month period and 10,547 claims for HCV-related medications were paid. The success rate of transitional case management referrals to drug treatment is over 90%. Training and clinical guidelines promote provider knowledge about HCV and contribute to quality HCV care for IDUs. Chart reviews of 2570 patients with HIV in 2004 documented HCV status 97.4% of the time, overall, in various settings. New HCV surveillance systems are operational. Despite this progress, significant challenges remain.DiscussionA comprehensive, public health approach, using multiple strategies across systems and mobilizing multiple sectors, can enhance IDUs access to HCV prevention and care. A holisitic approach with integrated services, including for HCV–HIV co-infected IDUs is needed. Leadership, collaboration and resources are essential.     

Feasibility in needle exchange programme: an evaluation of a pilot programme in Catania, Sicily

Introduction: Intravenous drug use (10 V) is a primary transmission route for HIV and other blood borne disease. A criminal approach to illicit drug use leads to aggressive attitudes towards drug users and forces them underground, thus hindering their access to Health Service outlets. A 6-month pilot Needle Exchange Programme was set up in Catania, with the aim of reducing the negative effects and consequences of drug use, preventing the spread of blood borne diseases by encouraging the use of clean needles and reduction of needle sharing. To establish contact with the hidden population of the city's, intravenous drug users (IDUs) and promote condom use and safer sex. Method: An equipped camper was parked daily in two of the city's main public squares according to a preset timetable, morning and afternoon. A flexible needle exchange policy, i.e. free clean needles given out regardless of those returned, was adopted as a strategy considered necessary in order to, ensure maximum user-friendliness. Safer shooting information leaflets were given out alongside material for the correct use of the condom and condoms. Result: The number of IDUs, contacted who had previously been referred to a National Health Service Drug Unit (Ser.T.) and not, and number of syringes exchanged were low but increased month by month. Conclusion: Future projects should be undertaken after building up, a collaborative network between Street Unit and local courts; the city police force; social service outlets; hospitals and other health outlets; Ser.T. units and local pharmacies. In the light of our current experience, the one to one strategy instead to the flexible strategy could lead to stricter adherence to harm reduction strategies amongst IDUs.     

Women injecting drug users in London: the extent and nature of their contact with drug and health services

Improved access to drug treatment and other health services remains central to HIV prevention and other harm reduction strategies among injecting drug users (IDUs) in the UK. Efforts have therefore been focused upon making such services more accessible and 'user friendly'. Women who use drugs are considered a 'hard to reach' population. This is largely based on data from a variety of official sources which have suggested that women are under-represented as clients of drug services. While current literature provides numerous explanations for this, there have been few empirical studies exploring the nature and extent of women's contact with such services. This paper presents findings from an European Community funded survey of women IDUs in London. Data from this survey suggest that women IDUs have surprisingly high levels of contact with a range of specialist and generic health services in relation to their drug use.     

Direct and indirect acquisition of syringes from syringe exchange programmes in Baltimore, Maryland, USA

Syringe exchange programmes (SEPs) are a fundamental source of sterile syringes and other health services for injection drug users (IDUs). However, various obstacles prevent many individuals from obtaining syringes from this source. As a result, some IDUs acquire syringes from “secondary exchangers”. The current study assessed the acquisition of syringes from the Baltimore City Needle Exchange Program (BNEP) as well as factors associated with obtaining syringes from the BNEP. Participants were asked to identify the colour of the cap of the most recently obtained syringe (red or grey cap suggested BNEP origins). In addition, support and risk network variables were examined. Although 38% reported using a syringe with a grey or red cap, only 7% reported that the BNEP was their primary source of syringes. Multivariate analyses showed that reporting the most recent syringe cap as red or grey was associated with obtaining syringes from the BNEP, obtaining syringes from a spouse, obtaining syringes from friends/neighbours, and number of drug users in their network. Based on these findings, encouraging secondary exchange is an effective method of providing injectors with syringes.     

Attitudes of police officers towards syringe access,occupational needle-sticks,and drug use: A qualitative study of one city police department in the United States

Removal of legal barriers to syringe access has been identified as an important part of a comprehensive approach to reducing HIV transmission among injecting drug users (IDUs). Legal barriers include both “law on the books” and “law on the streets,” i.e., the actual practices of law enforcement officers. Changes in syringe and drug control policy can be ineffective in reducing such barriers if police continue to treat syringe possession as a crime or evidence of criminal activity. Despite the integral role of police officers in health policy implementation, little is known of their knowledge of, attitudes toward, and enforcement response to harm-minimisation schemes. We conducted qualitative interviews with 14 police officers in an urban police department following decriminalisation of syringe purchase and possession. Significant findings include: respondents were generally misinformed about the law legalising syringe purchase and possession; accurate knowledge of the law did not significantly change self-reported law enforcement behaviour; while anxious about accidental needle sticks and acquiring communicable diseases from IDUs, police officers were not trained or equipped to deal with this occupational risk; respondents were frustrated by systemic failures and structural barriers that perpetuate the cycle of substance abuse and crime, but blamed users for poor life choices. These data suggest a need for more extensive study of police attitudes and behaviours towards drug use and drug users. They also suggest changes in police training and management aimed at addressing concerns and misconceptions of the personnel, and ensuring that the legal harm reduction programs are not compromised by negative police interactions with IDUs.     

Topic-Focused Bibliography: Syringe Exchange: HIV Prevention,Key Findings,and Future Directions

HIV among injecting drug users (IDUs) has now been documented in over 60 countries in the world, and there are an additional 40 countries where injecting drug use has been reported including widespread epidemics in Southeast and southern Asia and in Latin America. At present HIV infection is almost always fatal, and there is no promise that a preventive vaccine will become available soon. Given the enormity of the HIV epidemic among IDUs and the critical need to reduce the spread of HIV transmission to and from IDUs, prevention efforts are essential. Syringe-exchange programs have become a major component of HIV prevention strategies in most developed countries and work within the philosophy of harm reduction. Increasing access to sterile syringes has been met with considerable controversy. Opponents of syringe exchange have generally argued that increasing access to sterile syringes would simultaneously increase the number of injecting drug users, increase the frequency of injection for already active IDUs, and appear to “condone” an illegal behavior. To date many research studies and four major reviews of syringe exchange literature have been conducted. All studies thus far have shown no increase in illicit drug injection associated with syringe exchanges, and significant decrease in drug risk behaviors.
