Needle exchange programmes in Visegrad countries: a comparative case study of structural factors in effective service delivery.

BACKGROUND: Harm reduction services, despite their proved effectiveness in the prevention of infectious diseases, are still underdeveloped in several European states. The situation in the Visegrad Group countries is especially interesting. Notwithstanding the shared history, culture and political situation in the last decades, there are significant differences in the state of harm reduction between the countries. METHODS: The research applies the ecological systems model to identify the structural barriers and facilitators affecting organisations providing needle exchange services. It uses a comparative multiple case study design with embedded units of analysis complemented by within-case analysis to establish the relationship between the number and scope of identified factors and the performance of needle exchange services. The qualitative data were collected through semi-structured interviews with professionals working in needle exchange services in the Czech Republic, Poland, Slovakia and Hungary. Additionally, relevant documents, reports and online sources were analysed. RESULTS: A total of 24 themes (structural factors) were identified across 11 categories on 3 levels (mesosystem, exosystem, macrosystem). The list includes themes related to the broader society, politics and policy on state and local level, frameworks and amounts of funding, the situation on the education labour market, and attitudes of local communities, among others. The data shows that in the Czech Republic, many facilitators can be identified. In the three remaining countries, on the contrary, one can observe mostly barriers in NSP services delivery. CONCLUSIONS: The study addresses a highly unexplored topic of the functioning of harm reduction organisations in East-Central Europe. It sheds light on the environment of analysed services, identifying a number of structural factors in effective service delivery in the Czech Republic, Poland, Slovakia and Hungary. The research confirms the significant role of the barriers and facilitators in the services' performance. It highlights the relationships between various elements of the needle exchange programmes' environment, suggesting holistic strategies for addressing them. It also provides a potential starting point for further research.

Linkage into specialist hepatitis C treatment services of injecting drug users attending a needle syringe program-based primary healthcare centre.

Injecting drug users (IDUs), the key risk population for hepatitis C virus (HCV) infection, constitute just a small proportion of HCV treatment clients. This study describes an HCV treatment assessment model developed by an inner-city IDU-targeted primary healthcare (PHC) facility and, using a retrospective clinical audit, documents predictors of successful referrals to a tertiary liver clinic. Between July 2006-December 2010, 479 clients attended the PHC, of whom 353 (74%) were screened for HCV antibody. Sixty percent (212/353) tested positive, of whom 93% (197/212) were screened for HCV-RNA with 73% (143/197) positive. Referrals to a tertiary liver clinic were provided to 96 clients, of whom 68 (71%) attended. Eleven clients commenced antiviral therapy (AVT), with seven achieving sustained virological responses by December 2010. Clients who had not recently injected drugs and those with elevated ALT levels were more likely to attend the referrals, while those not prescribed psychiatric medications were more likely to commence AVT. The relatively high uptake of referrals, the number of individuals commencing AVT and final treatment outcomes are reasonably encouraging, highlighting the potential of targeted PHC services to facilitate reductions in liver disease burden among IDUs.

An integrated supervised injecting program within a care facility for HIV-positive individuals: a qualitative evaluation.

While there has been growing interest in comprehensive models of treatment and care for individuals living with HIV/AIDS, little attention has been given to the potential role that supervised injecting programs could play in increasing access to prevention and care services for HIV-positive injection drug users (IDU). We conducted 22 semi-structured interviews with HIV-positive IDU regarding a supervised injection program integrated in an HIV focused care facility known as the Dr. Peter Centre (DPC). We also interviewed seven staff members who supervise injections within the facility. All interviews were audio recorded, transcribed verbatim, and a thematic analysis was conducted. Participant and staff reports indicated that the integrated supervised injection program influenced IDUs' access to care by building more open and trusting relationships with staff, facilitating engagement in safer injection education and improving the management of injection-related infections. Participants and staff viewed the program as facilitating the delivery of care through mediating overdose risks, reducing the need to punitively manage drug use on-site and reducing the risks of encountering used syringes on the premises. For some participants, however, feelings of shame and fear of judgment in relation to their drug use limited initial uptake of the program. Our findings identify mechanisms through which integrated supervised injection programs may serve to better facilitate access and delivery of comprehensive care for HIV-positive IDU and highlight the benefits of addressing HIV-positive IDUs' drug use in the context of comprehensive models of healthcare.

Pushing the boundaries of outreach work: the case of needle exchange outreach programs in Canada.

In this paper, we examine the challenges of defining the boundaries of outreach work using the example of needle exchange programs. In particular, we examine the multiple and inter-related factors that extend needle exchange outreach work beyond its official mandate. Using semi-structured interviews, 59 workers at 15 programs in Ontario, Canada were asked questions about operational policies and routines. An iterative and inductive analytic process was used. Over time, most outreach workers develop a well-defined sense of the activities they consider to be consistent with a harm reduction approach and the types of conduct that are considered to be acceptable and professional. Workers conceptualize their roles to encompass education and support but are reluctant to impose a rigid definition of their roles. A pragmatic and humble stance combined with strong beliefs in social justice encourages workers to find informal solutions to meet client needs that extend beyond the program mandate. As a result, doing 'extra' is the norm. These extra efforts are informal, but often regular, expansions of the service complement. Construction of flexible boundaries provides opportunities to meet many client needs and unexpected situations; however, going the extra-mile strains resources. A minority of workers blur the boundaries between private and professional lives. Further, a variety of personal, social and socio-political forces encourage outreach workers to continually redefine the boundaries of their roles and service complements.

Operating needle exchange programmes in the hills of Thailand.

Injecting drug use is increasingly markedly amongst the ethnically distinct Hilltribe peoples of northern Thailand in the notorious 'Golden Triangle'. This paper reports on the establishing of needle exchanges in three remote Hilltribe villages, examining the success and the failure. Up to 60% of adult males and a smaller percentage of adult females in these villages are habitual users of opium and/or heroin. Overcoming initial concern that needle distribution would encourage increased use, the villagers themselves have assumed responsibility for much of the needle exchange operation. Prior to the introduction of the needle exchanges all the injecting drug users were sharing needles. This behaviour changed significantly with the introduction of the exchanges. Reluctance on the part of locally-based government officials to participate fully in the programme created difficulties in maintaining needle supplies which saw some resumption in needle sharing. HIV seroprevalence rates amongst the tested injecting drug users remained fairly stable at 33% in February 1993 and 32% in February 1994. The conclusion can be drawn that needle exchange programmes are operable in the Hilltribe context and that they are the best means of limiting HIV/AIDS transmission amongst injecting drug users and the wider community. The success of needle exchange programmes, however, is dependent upon co-operation from various government agencies and non-government agencies, in addition to the local communities. To this end mechanisms ensuring co-operation, training, monitoring and evaluation need to be developed alongside the introduction of needle exchanges.

PIP: Injecting drug use is increasing markedly among the ethnically distinct Hilltribe people of northern Thailand in the notorious Golden Triangle. This paper reports on the establishment of needle exchanges in 3 remote Hilltribe villages. The needle and syringe exchanges were established in 3 villages: Anamai Village 1, 2, and 3, each with an average of 47 households and 5-6 people per household. Altogether there were 46 injecting drug users participating: 16 from Anamai Village 1; 12 from Anamai Village 2; and 18 from Anamai Village 3. Up to 60% of adult males and a smaller percentage of adult females in these villages were habitual users of opium and/or heroin. Through a series of meetings in the villages various means available to prevent the transmission of HIV/AIDS in an injecting drug use context were discussed. The villagers themselves have assumed responsibility for much of the needle exchange operation. The sharing of needles by injecting drug users changed significantly with the introduction of the exchanges. Reluctance on the part of local government officials to participate in the program created difficulties in maintaining needle supplies, which led to some resumption in needle sharing. The needle and syringe exchanges in November 1992 supplied 5000 1 cc needle and syringe fits, a 1-years' supply. HIV seroprevalence rates among the tested injecting drug users remained fairly stable at 5 cases (33%) of 15 IDUs tested in February 1993. In February 1994, 8 (32%) of 25 IDUs tested were found to be HIV seropositive. The 17 men found to be HIV negative in February 1994 despite their injecting behavior would seem to indicate that the needle exchange programs in the Hilltribe context are effective in limiting HIV/AIDS transmission among injecting drug users and the wider community. The success of needle exchange programs is dependent upon cooperation from various government agencies and nongovernment agencies as well as the local communities.
