Hepatitis C prevention education needs to be grounded in social relationships

A Collaborative Approach to Understanding the Intersections of Practice and Policy for Peers in the Alcohol and Other Drugs Sector

INTRODUCTION

Peers in the alcohol and other drug sectors possess lived-living experience (LLE) crucial for shaping community care. However, genuine consumer collaboration is often confounded by stigma. This study examined peers' perceptions, exploring their experiences regarding workforce dynamics, policy implications, and impacts on health equity. In presenting the research, we sought to synthesise the research methods and illustrate the methodological innovation and knowledge production in substance use research through authentic collaboration.

METHODS

We purposively sampled peer networks and community organisations, involving peer-researchers in planning, design, and analysis. We conducted semi-structured digital interviews with 18 peers and applied iterative coding to analyse the data.

RESULTS

This collaborative process provided nuanced insights into sectoral challenges. Peers expressed emotional strain revisiting personal substance use experiences, blurring personal and professional boundaries. Tokenistic peer involvement critiques underscored the need for genuine leadership and organisational support.

CONCLUSION

We advocate for a shift towards equitable and inclusive policy development through both organisational and systemic restructuring. However, these changes are hamstrung by broader policy frameworks, which require a shift to peer-led principles, ensuring the expertise of peers is genuinely valued. Policymakers should invest in expanding peer frameworks, acknowledging the diversity within communities of people who use drugs to improve health equity and public health outcomes. This innovative approach to substance use research emphasises the transformative impact of integrating LLE into research.

Professional perspectives on serodiscordant family service provision in the context of blood-borne viruses

In recognition of the broader relational aspects of viral infections, family support is considered important when someone is diagnosed with a blood-borne virus (BBV), such as HIV, hepatitis C (HCV) and hepatitis B (HBV). However, families' own support needs are often not a priority in service provision within the BBV sector. In this article, we draw on qualitative interviews with 20 key informants working in various professional capacities in health, social policy, care and advocacy sectors in Australia, and explore their experiences and perspectives on family inclusivity in their services. Overall, key informants acknowledged the diversity of what constitutes family, and consistently viewed family engagement as beneficial to both diagnosed individuals and the wider familial networks affected by a diagnosis. However, prioritising individual care in support services presented barriers to engaging families, which are further complicated by the role of stigma in shaping the social realities of living with a BBV. Increasing understanding in service provision settings that serodiscordance can be a family experience has the potential to widen this analytic lens to consider the support needs of families in their own right.

The role of gender and power dynamics in injection initiation events within intimate partnerships in the US-Mexico border region

Women's initiation into injection drug use often establishes a pattern of risk following first injection. This study explored sources of gendered power dynamics in injection initiation experiences for people who inject drugs. A qualitative subsample from two prospective community-recruited cohorts of people who inject drugs in San Diego and Tijuana provided data on the contexts surrounding injection initiation processes. Intimate partnerships were identified in initiation; sub-themes were identified drawing on three concepts within the theory of gender and power. With reference to sexual division of labour, men were often responsible for access to resources in partnerships across both contexts, although there were limited accounts of women obtaining those resources. Extending the structure of power, women in San Diego reported that initiation events involving an intimate partner occurred from a position of vulnerability but expressed greater agency when providing initiation assistance. With regard to structure of cathexis, social norms proscribing injection initiation among women exist, particularly in Tijuana. Gendered power dynamics are a multifaceted component of injection initiation events, especially for women in intimate partnerships. These results stress the need for nuance in understanding the intersection of risk, gender and harm reduction within injection initiation events across socio-cultural contexts.

Who goes first? Understanding hepatitis C risk among injecting networks in the prison setting

BACKGROUND

Hepatitis C (HCV) is a blood-borne virus that is most commonly transmitted through shared injecting equipment. Due to the criminalisation of injecting drug use, HCV is highly prevalent among those incarcerated. Using a risk environment framework, this qualitative study sought to understand the role of HCV risk within injecting networks in the prison setting.

METHODS

Thirty-two adult prisoners (n=24 men; n=8 women) with a history of injecting drug use participated in this qualitative sub-study. Participants were recruited across four correctional centres.

RESULTS

Social, economic, and environmental risk factors contributed to injecting practices within prison. Commonly, the person supplying the drugs injected first, with the person who owns the injecting equipment going next. HCV did not regularly factor into determining order of injection within networks (i.e., first, second, third), although it was reported that some prisoners claimed not to have HCV in efforts to "jump the queue".

CONCLUSION

Social, economic, and environmental risk factors contribute to negotiation of injecting order among people who inject drugs in prison. Risk of HCV exposure rarely influenced the injecting order. Harm reduction strategies should consider the social factors influencing injecting drug use in the prison setting especially to optimise the population benefits of the roll-out of highly effective HCV treatments.

Families Living with Blood-Borne Viruses: The Case for Extending the Concept of "Serodiscordance"

The concept of “serodiscordance” (mixed infection status) is primarily associated with epidemiological concerns about HIV transmission risk in couples. We make the case for extending this concept to include families with mixed HIV and viral hepatitis status. Social research on couples with mixed HIV and hepatitis C status has laid an important foundation for illuminating how experiences of serodiscordance within intimate partnerships are much broader than concerns about risk. This body of work attests to serodiscordance holding promise as a valuable concept for understanding viral infections as socially situated and intensely relational phenomena. However, serodiscordance is still limited as a concept because of its near universal focus on couples. It is rarely applied to wider relationships, including family networks beyond the couple. Despite evidence in the literature that families are affected by blood-borne viruses in multiple social, emotional, financial, and generational ways, the concept of serodiscordance does not capture these broader dynamics. Making serodiscordance more inclusive is an important step in recognising the diverse ways families' everyday lives, relationships, and futures can be entangled with HIV, hepatitis C, and hepatitis B, and for understanding how today's era of effective treatment options might shape the “family life” of viral infections.

Practices of partnership: Negotiated safety among couples who inject drugs

Despite the majority of needle-syringe sharing occurring between sexual partners, the intimate partnerships of people who inject drugs have been largely overlooked as key sites of both hepatitis C virus prevention and transmission, and risk management more generally. Drawing on interviews with 34 couples living in inner-city Australia, this article focuses on participants' accounts of 'sharing'. While health promotion discourses and conventional epidemiology have tended to interpret the practice of sharing (like the absence of condom use) in terms of 'noncompliance', we are interested in participants' socially and relationally situated 'rationalities'. Focussing on participants' lived experiences of partnership, we endeavour to make sense of risk and safety as the participants themselves do.How did these couples engage with biomedical knowledge around hepatitis C virus and incorporate it into their everyday lives and practices? Revisiting and refashioning the concept of 'negotiated safety' from its origins in gay men's HIV prevention practice, we explore participants' risk and safety practices in relation to multiple and alternative framings, including those which resist or challenge mainstream epidemiological or health promotion positions. Participant accounts revealed the extent to which negotiating safety was a complex and at times contradictory process, involving the balancing or prioritising of multifarious, often competing, risks. We argue that our positioning of participants' partnerships as the primary unit of analysis represents a novel and instructive way of thinking about not only hepatitis C virus transmission and prevention, but the complexities and contradictions of risk production and its negotiation more broadly.

Understanding decisions made about hepatitis C treatment by couples who inject drugs

Efforts to increase the number of people having hepatitis C virus (HCV) treatment require understanding how to best deliver services to meet consumers' needs. The general health literature has examined the role that partners can play in supporting health outcomes. This study examines the experiences of couples who inject drugs in relation to knowledge of, decisions about and management of HCV treatment. This is a qualitative interview study of people who inject drugs in couples. Participants were recruited from harm reduction services in two major Australian cities. Couples were interviewed separately. Data were examined using the couple as the unit of analysis and to identify patterns of experience related to the HCV serostatus of couples. Knowledge of HCV and HCV treatment was low and variable but showed some relationship to serostatus. Decisions about HCV treatment were deeply informed by concerns regarding treatment side effects. Positive concordant couples considered 'staging' treatment to ensure that each partner could (in turn) care for the other. People with HCV in serodiscordant relationships may need specific support regarding HCV treatment information. Within positive concordant partnerships, our data indicated the need to support the HCV-positive 'carer' during their partner's treatment. Changing treatment regimens, and their anticipated lower side effect profiles, will need to be actively promoted to ensure that couples understand how these changes affect their treatment options.

Modeling hepatitis C virus transmission among people who inject drugs: Assumptions, limitations and future challenges

The discovery of highly effective hepatitis C virus (HCV) treatments has led to discussion of elimination and intensified interest in models of HCV transmission. In developed settings, HCV disproportionally affects people who inject drugs (PWID), and models are typically used to provide an evidence base for the effectiveness of interventions such as needle and syringe programs, opioid substitution therapy and more recently treating PWID with new generation therapies to achieve specified reductions in prevalence and / or incidence. This manuscript reviews deterministic compartmental S-I, deterministic compartmental S-I-S and network-based transmission models of HCV among PWID. We detail typical assumptions made when modeling injecting risk behavior, virus transmission, treatment and re-infection and how they correspond with available evidence and empirical data.

Higher risk of incident hepatitis C virus among young women who inject drugs compared with young men in association with sexual relationships: a prospective analysis from the UFO Study cohort

BACKGROUND

Female injection drug users (IDUs) may report differences in injection behaviours that put them at greater risk for hepatitis C virus (HCV). Few studies have examined these in association with HCV incidence.

METHODS

Longitudinal data from a cohort of 417 HCV-uninfected IDU aged 30 or younger were analysed. Cox proportional hazards was used to model female sex as a predictor of new HCV infection. General estimating equation (GEE) analysis was used to model female sex as a predictor of HCV-associated risk behaviour prospectively.

RESULTS

Women were significantly more likely than men to become infected with HCV during study follow-up (HR 1.4, p<0.05), and were also more likely than men to report high-risk injecting behaviours, especially in the context of sexual and injecting relationships. Sex differences in injecting behaviours appeared to explain the relationship between sex and HCV infection.

CONCLUSIONS

Young women's riskier injection practices lead to their higher rates of HCV infection. Further study on the impact of intimate partnership on women's risk behaviour is warranted.
