Needle and syringe programs for reducing blood-borne diseases among people who inject drugs in sub-Saharan Africa: a scoping review protocol

OBJECTIVE

This review will identify, explore, and map the literature on the characteristics and implementation modalities of needle and syringe programs for reducing blood-borne diseases among people who inject drugs in sub-Saharan Africa compared with the recommended standards by the World Health Organization and AIDS Projects Management Group.

INTRODUCTION

Sub-Saharan Africa bears a disproportionate burden of infectious diseases and HIV/AIDS. Needle and syringe programs have been shown to be effective in preventing transmission of infections among those who inject drugs by providing them with sterile injection equipment. The programs may also serve as avenues for addressing other issues that affect this population.

INCLUSION CRITERIA

This review will consider published and unpublished studies on needle and syringe programs as a method of preventing blood-borne infections among people who inject drugs in sub-Saharan Africa. The review will consider quantitative, qualitative, and mixed methods study designs, as well as systematic reviews and text and opinion papers.

METHODS

The electronic databases to be searched include MEDLINE, African Journals Online, CINAHL, the Cochrane Library, Embase, and TRoPHI. We will also search sources of unpublished studies and gray literature (conference abstracts, theses, etc). The search will be restricted to studies in English, with no date limit. Data extraction will be done by two independent reviewers, guided by an extraction tool developed by the reviewers. Key information, such as author, reference, and findings relevant to the review questions, will be obtained. The results will be presented as graphs, figures, and tables accompanied by a narrative summary.

Rationalities of Space and Drug-Related Harms: Accounts of People Who Inject Drugs in Nigeria

BACKGROUND

Studies have examined how people who inject drugs (PWID) navigate public spaces for drug consumption, but little is known about consumption of drugs in private apartments. This study explores social, structural and physical environment factors influencing injecting practices and the rationalities shaping how PWID make decisions about where to consume drugs.

METHODS

The study is based on qualitative data from 41 in-depth interviews conducted with both homeless and housed PWID recruited through snowball sampling in Uyo, Nigeria. Thematic analysis, framed by the theoretical constructs of structural and everyday violence, and situated rationality theories, was undertaken on transcripts.

RESULTS

Analysis revealed different socio-spatial rationalities underlying decisions about where to use drugs: avoidance of police arrest, convenience and relaxation, avoidance of drug sharing, avoidance of drug-scene violence, and stigma and shame. These factors show the impacts of social, structural and physical environment factors on the lived experiences of PWID. Injecting in private apartments potentially offset the risk of stigma, police arrest and violence linked to public injecting, but increase the risk of overdose and sharing of drugs and needle-syringes based on social relations of trust.

CONCLUSIONS

Findings show that PWID chose between competing risks when deciding on where to inject drugs. Interventions should consider the situated contexts of risk, and adapt harm reduction measures to the risk profile of different populations of PWID.

“…I can use any syringe I find”: contextual determinants of HIV risk in public injecting settings in Nigeria

Purpose

The purpose of this study is to explore the contextual determinants of HIV risk among people who inject drugs (PWID) in public settings in Nigeria.

Design/methodology/approach

In-depth, individual interviews were conducted with 29 street-based PWID recruited through snowball sampling in Uyo, Nigeria. Interviews were tape-recorded, transcribed, coded and analysed hematically.

Findings

Homelessness and withdrawal pains encouraged consumption of drugs in public spaces (e.g. bunks, public parks). Conversely, the benefits of participation in street drug-use scenes, including reciprocity norms that guarantee free drugs during withdrawal and protection during overdose, fostered a preference for public injecting. Although participants recognized the need to inject with sterile syringes, scarcity of syringes compelled them to improvise with old syringes or share syringes, increasing risk for HIV transmission. HIV risk was exacerbated by unlawful and discriminatory policing practices, which deterred possession of syringes and encouraged risky behaviours such as rushing injection and sharing of equipment.

Practical implications

Contextual factors are key determinants of HIV risk for street-based PWID. Implementation of needle and syringe programmes as well as reforming legal frameworks and policing practices to support harm reduction are needed responses.

Originality/value

This is one of very few qualitative studies that explore risk factors for HIV transmission among PWID in West Africa. The focus on scarcity of sterile syringes and HIV risk is unique and has important policy implications.

The Risk Environment for Adopting and Continuing Injecting Drug Use: A Qualitative Study in Uyo, Nigeria

Background: The bulk of research on adoption of injecting is from Europe and America, despite the existence of syndemics of drug injecting, HIV, and viral hepatitis globally. Objectives: This study explores adoption and continuation of injecting drug use. Methods: The study draws on in-depth interviews with 41 (n = 41) current male and female people who inject drugs recruited via snow-ball sampling in Uyo, Nigeria. A thematic and descriptive analysis was undertaken informed by the risk environment framework and focused on accounts of the factors influencing the process. Results: Accounts emphasized injecting adoption and continuation as a process influenced by individual, social, and structural factors within the risk environment, including concerns for pleasure/efficiency, prestige, exposure to/support for injecting within peer and sexual relationships, availability and purity of drugs, and dependence and increased cost of drug use. Conclusions/implications: Findings highlight the need to prevent adoption of injecting, reduce prevalence of injecting, and promote safe injecting through multi-level interventions, including peer-driven education, drug treatment services, needle and syringe distribution, oral drug substitution, and law enforcement targeting drug suppliers. The need for equivalent pleasure with minimal risk points to the strategic importance of peer interactions for inculcating new understandings of drug use and pleasure.
