This meta-analysis provides strong evidence that opioid substitution therapy improves several key outcomes of the HIV care continuum among people who inject drugs, including recruitment onto antiretroviral therapy, retention in care, adherence, and viral suppression.

BackgroundThe integration of HIV care into primary care services is one of the strategies proposed to increase access to treatment for people living with HIV/AIDS in high HIV burden countries. However, how best to do this is poorly understood. This study documents different factors influencing models of integration within clinics.MethodsUsing methods based on the meta-ethnographic approach, we synthesised the findings from three qualitative studies of the factors that influenced integration of HIV care into all consultations in primary care. The studies were conducted amongst staff and patients in South Africa during a randomised trial of nurse initiation of antiretroviral therapy (ART) and integration of HIV care into primary care services – the Streamlining Tasks and Roles to Expand Treatment and Care for HIV (STRETCH) trial. Themes from each study were identified and translated into each other to develop categories and sub-categories and then to inform higher level interpretations of the synthesised data.ResultsClinics varied as to how HIV care was integrated. Existing administration systems, workload and support staff shortages tended to hinder integration. Nurses’ wanted to be involved in providing HIV care and yet also expressed preferences for developing expertise in certain areas and for establishing good nurse patient relationships by specialising in certain services. Patients, in turn, were concerned about the stigma of separate HIV services and yet preferred to be seen by nurses with expertise in HIV care. These factors had conflicting effects on efforts to integrate HIV care.ConclusionLocal clinic factors and nurse and patient preferences in relation to care delivery should be taken into account in programmes to integrate HIV care into primary care services. The integration of medical records, monitoring and reporting systems would support clinic based efforts to integrate HIV care into primary care services.

Background and objectives Promoted globally as an evidence-based intervention in the prevention of HIV and treatment of heroin addiction among people who inject drugs (PWID), opioid substitution treatment (OST) can help control emerging HIV epidemics among PWID. With implementation in December 2014, Kenya is the third Sub-Saharan African country to have introduced OST. We combine dynamic mathematical modelling with qualitative sociological research to examine the ‘promise of methadone’ to Kenya. Methods, setting and participants We model the HIV prevention impact of OST in Nairobi, Kenya, at different levels of intervention coverage. We draw on thematic analyses of 109 qualitative interviews with PWID, and 43 with stakeholders, to chart their narratives of expectation in relation to the promise of methadone. Results The modelled impact of OST shows relatively slight reductions in HIV incidence (5–10%) and prevalence (2–4%) over 5 years at coverage levels (around 10%) anticipated in the planned roll-out of OST. However, there is a higher impact with increased coverage, with 40% coverage producing a 20% reduction in HIV incidence, even when accounting for relatively high sexual transmissions. Qualitative findings emphasise a culture of ‘rationed expectation’ in relation to access to care and a ‘poverty of drug treatment opportunity’. In this context, the promise of methadone may be narrated as a symbol of hope—both for individuals and community—in relation to addiction recovery. Conclusions Methadone offers HIV prevention potential, but there is a need to better model the effects of sexual HIV transmission in mediating the impact of OST among PWID in settings characterised by a combination of generalised and concentrated epidemics. We find that individual and community narratives of methadone as hope for recovery coexist with policy narratives positioning methadone primarily in relation to HIV prevention. Our analyses show the value of mixed methods approaches to investigating newly-introduced interventions.

A qualitative analysis of transitions to heroin injection in Kenya: implications for HIV prevention and harm reduction

BackgroundHeroin injection is emerging as a significant dimension of the HIV epidemic in Kenya. Preventing transitions to injecting drug use from less harmful forms of use, such as smoking, is a potentially important focus for HIV prevention. There is, however, little evidence to support comprehensive programming in this area, linked to a shortage of analysis of the social and structural context for transitions, particularly in low-income settings. We explore accounts of transitions from smoking to injecting in Kenya to understand the role of individual, social and structural processes.MethodsWe combine data from two separate studies conducted in Kenya: an in-depth qualitative study of HIV care access for people who inject drugs (study 1) and an ethnographic study of the political economy of the heroin trade in Kenya (study 2). In-depth interviews with PWID and community observation from study 1 are triangulated with accounts from stakeholders involved in the heroin trade and documentary data from study 2.ResultsPeople who inject drugs link transitions to injecting from smoking to a range of social and behavioural factors, as well as particular aspects of the local drug supply and economy. We present these results in the form of two narratives that account for factors shaping transitions. A dominant narrative of ‘managing markets and maintaining a high’ results from a process of trying to manage poverty and a shifting heroin supply, in the context of deepening addiction to heroin. A secondary narrative focuses on people’s curiosity for the ‘feeling’ of injecting, and the potential pleasure from it, with less emphasis on structural circumstances.ConclusionsThe narratives we describe represent pathways through which structural and social factors interact with individual experiences of addiction to increase the risk of transitions to injecting. In response, HIV and harm reduction programmes need combinations of different strategies to respond to varied experiences of transitions. These strategies should include, alongside behaviour-oriented interventions, structural interventions to address economic vulnerability and the policing of the drug supply.

Navigating the poverty of heroin addiction treatment and recovery opportunity in Kenya: Access work, self-care and rationed expectations

Tim Rhodes; James Ndimbii; Andy Guise; Lucy Cullen; Sylvia Ayon

Drawing on the analyses of qualitative interview accounts of people who inject heroin in Kenya, we describe the narration of addiction treatment access and recovery desire in conditions characterised by a ‘poverty of drug treatment opportunity’. We observe the performance of addiction recovery narrative in the face of heavy social constraints limiting access to care. Fee-based residential rehabilitation (‘rehab’) is the only treatment locally available and inaccessible to most. Its recovery potential is doubted, given normative expectations of relapse. Treating drug use is a product of tightly bounded agency. Individuals enact strategies to maximise their slim chances of treatment access (‘access work’), develop self-care alternatives when these fail to materialise and ration their care expectations. The use of rehab as a primary means of respite and harm reduction rather than recovery and the individuation of care in the absence of an enabling recovery environment are key characteristics of drug treatment experience. The recent incorporation of ‘harm reduction’ into policy discourses may trouble the primacy of recovery narrative in addiction treatment and in how treatment desires are voiced. The diversification of drug treatments in combination with social interventions enabling their access are fundamental.

ABSTRACT People who use drugs in many contexts have limited access to opioid substitution therapy and HIV care. Service integration is one strategy identified to support increased access. We reviewed and synthesized literature exploring client and provider experiences of integrated opioid substitution therapy and HIV care to identify acceptable approaches to care delivery. We systematically reviewed qualitative literature. We searched nine bibliographic databases, supplemented by manual searches of reference lists of articles from the database search, relevant journals, conferences, key organizations and consultation with experts. Thematic synthesis was used to develop descriptive themes in client and provider experiences. The search yielded 11 articles for inclusion, along with 8 expert and policy reports. We identify five descriptive themes: the convenience and comprehensive nature of co-located care, contrasting care philosophies and their role in shaping integration, the limits to disclosure and communication between clients and providers, opioid substitution therapy enabling HIV care access and engagement, and health system challenges to delivering integrated services. The discussion explores how integrated opioid substitution therapy and HIV care needs to adapt to specific social conditions, rather than following universal approaches. We identify priorities for future research. Acceptable integrated opioid substitution therapy and HIV care for people who use drugs and providers is most likely through co-located care and relies upon attention to stigma, supportive relationships and client centred cultures of delivery. Further research is needed to understand experiences of integrated care, particularly delivery in low and middle income settings and models of care focused on community and non-clinic based delivery.

UNLABELLED Background As efforts continue to increase rates of HIV testing and condom use among at-risk communities in England, organisations have sought use social media for health promotion interventions. As part of a wider evaluation of It Starts With Me (ISWM), a sexual health promotion intervention in England targeting gay and bisexual men and African people through Facebook, this study sought to explore how the online environment shapes end user engagement with sexual health interventions. A primary objective was to explore how privacy concerns can act as a barrier to engagement for the audience of ISWM. METHODS A purposive sample of 40 individuals were recruited, who were targeted by the intervention for in-depth interviews. Data collection was in two phases. In the first phase, individuals were sampled based on engagement with online health interventions in general, while in the second phase, all individuals were sampled on the basis of engagement with the intervention. RESULTS Privacy concerns related to the ecology of social networking sites, issues with implied disclosure and discrimination, as well as uncertainty over control of data. These concerns limited the organic reach of the intervention by confining the intervention to those who already held the norms diffused through it, and by discouraging participants from sharing and commenting on content. CONCLUSIONS Care should be taken to address concerns when designing interventions delivered through social media. Gated interventions may be more beneficial for marginalised communities, while large-scale interventions such as ISWM may provide a useful backdrop for face-to-face interventions.

BACKGROUND Illegal drug markets are shaped by multiple forces, including local actors and broader economic, political, social, and criminal justice systems that intertwine to impact health and social wellbeing. Ethnographic analyses that interrogate multiple dimensions of drug markets may offer both applied and theoretical insights into drug use, particularly in developing nations where new markets and local patterns of use traditionally have not been well understood. This paper explores the emergent drug market in Kisumu, western Kenya, where our research team recently documented evidence of injection drug use. METHODS Our exploratory study of injection drug use was conducted in Kisumu from 2013 to 2014. We draw on 151 surveys, 29 in-depth interviews, and 8 months of ethnographic fieldwork to describe the drug market from the perspective of injectors, focusing on their perceptions of the market and reports of drug use therein. RESULTS Injectors described a dynamic market in which the availability of drugs and proliferation of injection drug use have taken on growing importance in Kisumu. In addition to reports of white and brown forms of heroin and concerns about drug adulteration in the market, we unexpectedly documented widespread perceptions of cocaine availability and injection in Kisumu. Examining price data and socio-pharmacological experiences of cocaine injection left us with unconfirmed evidence of its existence, but opened further possibilities about how the chaos of new drug markets and diffusion of injection-related beliefs and practices may lend insight into the sociopolitical context of western Kenya. CONCLUSIONS We suggest a need for expanded drug surveillance, education and programming responsive to local conditions, and further ethnographic inquiry into the social meanings of emergent drug markets in Kenya and across sub-Saharan Africa.

Access to HIV treatment and care for people who inject drugs in Kenya: a short report.

ABSTRACT People who inject drugs (PWID) experience a range of barriers to HIV treatment and care access. The Kenyan government and community-based organisations have sought to develop HIV care for PWID. A principal approach to delivery in Kenya is to provide care from clinics serving the general population and for this to be linked to support from community-based organisations providing harm reduction outreach. This study explores accounts of PWID accessing care in Kenya to identify care barriers and facilitators. PWID accounts were collected within a qualitative longitudinal study. In-depth interviews with PWID living with HIV (n = 44) are combined with interviews with other PWID, care providers and community observation. Results show that some PWID are able to access care successfully, whilst other PWID report challenges. The results focus on three principal themes to give insights into these experiences: the hardship of addiction and the costs of care, the silencing of HIV in the community and then discrimination and support in the clinic. Some PWID are able to overcome, often with social and outreach support, barriers to clinic access; for others, the challenges of addiction, hardship, stigma and discrimination are too constraining. We discuss how clinics serving the general population could be further adapted to increase access. Clinic-based care, even with community links, may, however, be fundamentally challenging for some PWID to access. Additional strategies to develop stand-alone care for PWID and also decentralise HIV treatment and care to community settings and involve peers in delivery should be considered.

BACKGROUND AND AIM Understanding the experience of initiating injection drug use and its social contexts is crucial to inform efforts to prevent transitions into this mode of drug consumption and support harm reduction. We reviewed and synthesized existing qualitative scientific literature systematically to identify the socio-structural contexts for, and experiences of, the initiation of injection drug use. METHODS We searched six databases (Medline, Embase, PsychINFO, CINAHL, IBSS and SSCI) systematically, along with a manual search, including key journals and subject experts. Peer-reviewed studies were included if they qualitatively explored experiences of or socio-structural contexts for injection drug use initiation. A thematic synthesis approach was used to identify descriptive and analytical themes throughout studies. RESULTS From 1731 initial results, 41 studies reporting data from 1996 participants were included. We developed eight descriptive themes and two analytical (higher-order) themes. The first analytical theme focused on injecting initiation resulting from a social process enabled and constrained by socio-structural factors: social networks and individual interactions, socialization into drug-using identities and choices enabled and constrained by social context all combine to produce processes of injection initiation. The second analytical theme addressed pathways that explore varying meanings attached to injection initiation and how they link to social context: seeking pleasure, responses to increasing tolerance to drugs, securing belonging and identity and coping with pain and trauma. CONCLUSIONS Qualitative research shows that injection drug use initiation has varying and distinct meanings for individuals involved and is a dynamic process shaped by social and structural factors. Interventions should therefore respond to the socio-structural influences on injecting drug use initiation by seeking to modify the contexts for initiation, rather than solely prioritizing the reduction of individual harms through behavior change.
