Coalition building by drug user and sex worker community-based organizations in Vietnam can lead to improved interactions with government agencies: a qualitative study

How do relational practices co-constitute care for people who use drugs? The social and political dimensions of peer-led harm reduction

INTRODUCTION

People who use drugs have a long history of mobilising to reduce harm within their communities, significantly influencing harm reduction efforts globally. Peers with lived experience contribute through needle exchange programs, harm reduction education, and community-based research. Despite facing stigma, their initiatives have generated multiple benefits for communities. Collaborations between peers and researchers are increasingly recognised, emphasising meaningful participation in decisions affecting their lives. This paper focuses on the role of peers in mitigating drug-related risks and harms through community care.

METHODS

Semi-structured interviews were conducted with 30 people who use drugs, exploring peer support and harm reduction. Data were analysed by the lead author and a coding framework was developed in which key theme-categories were organised. Theoretical framing from science and technology studies informed analysis, recognising the political dimensions of research.

RESULTS

Peers play a crucial role in bridging gaps in formal services, offering stigma-free, relational care spaces. These spaces, both physical and social, affirm dignity and solidarity, countering marginalisation. Participants highlight the importance of peer involvement in driving change, promoting safer use practices, and advocating for a holistic harm reduction approach that considers systemic factors.

CONCLUSIONS

Our data highlight the vital role of peer connections and peer-led harm reduction practices in fostering safety, solidarity, and connection among communities of people who use drugs. Future research should continue to explore peer-led initiatives within evolving healthcare contexts, considering broader social dynamics and employing innovative conceptual frameworks to promote equitable peer-led harm reduction strategies.

Gender Differences in HIV, HCV risk and Prevention Needs Among People who Inject drug in Vietnam

We examined gender differences among people who inject drug (PWID) in Hai Phong, Vietnam in term of blood-borne infections, risk behaviors, and access to care. Using respondent-driven-sampling surveys, we recruited 3146 PWID from 2016 to 2018. Inclusion criteria included a positive urine test for heroin and recent injection marks. There were 155 female PWID (4,9%), including 82 at RDS-2016, 32 at RDS-2017 and 38 at RDS-2018. The age mean was 36.3 ± 7.2 years. The majority of female PWID had less than high school education (90.9%) and were unemployed (51.3%). There was no difference in the proportion of HIV and HCV positive by gender. However, women had several significant differences in risk behaviors than men in multivariable logistic regression. Being a woman was independently associated with being unemployed, being a sex worker, having unstable housing, having uses drugs for less than 5 years, more use of methamphetamine, having a partner who ever injected drugs, and less access to methadone treatment. Interventions targeting female PWID are needed, possibly through community organizations and peer educators.

The methamphetamine epidemic among persons who inject heroin in Hai Phong, Vietnam

AIMS

To describe the current methamphetamine (MA) use epidemic among persons who inject heroin (PWID) in Hai Phong, Vietnam, and consider possibilities for mitigating adverse effects of methamphetamine use.

METHODS

This study conducted surveys of PWID in 2016, 2017, and 2018 (N = 1383, 1451, and 1445, respectively). Trained interviewers administered structured interviews covering drug use histories, current drug use, and related risk behaviors. The study used urinalysis to confirm current drug use, and conducted HIV and HCV testing.

RESULTS

Participants were predominantly male (95%), mean age of 40, and all reported injecting heroin. Respondents' reports of initiating MA use were rare up through early 2000s but increased exponentially through the mid-2010s. MA use was predominantly "smoking," heating the drug and inhaling the vapor using a pipe; injecting MA was rare. Current (past 30 day) MA use appears to have plateaued in 2016-2018 with 53-58% of participants reporting no use in the last 30 days, 37-41% reporting low to moderate use (1 to 19 days in last 30 days), and 5-7% reporting very frequent use (20 or more days in last 30 days). This plateau reflects a rough balance between new users and individuals ceasing use.

CONCLUSIONS

MA use has become a substantial public health problem among PWID in Hai Phong. Initiation into MA use rose exponentially from 2005 to about 2015. Use of MA will likely continue for a substantial number of PWID. Currently, no medication is approved for treating MA disorders in Vietnam. Current psychosocial treatment requires highly trained counselors and months of treatment, so that psychosocial treatment for all PWID with MA disorders is likely beyond the resources available in a middle-income country such as Vietnam. Harm reduction programs implemented by community-based organization staff may provide a way to rapidly address aspects of the current MA epidemic. Such programs could emphasize social support for reducing use where possible and for avoiding escalation of use among persons continuing to use.

Peer driven or driven peers? A rapid review of peer involvement of people who use drugs in HIV and harm reduction services in low- and middle-income countries

Introduction

Peer involvement of people who use drugs within HIV and harm reduction services is widely promoted yet under-utilised. Alongside political and financial barriers is a limited understanding of the roles, impacts, contexts and mechanisms for peer involvement, particularly in low- and middle-income settings. We conducted a rapid review of available literature on this topic.

Methods

Within a community-academic partnership, we used a rapid review approach, framed by realist theory. We used a network search strategy, focused on core journals and reference lists of related reviews. Twenty-nine studies were included. We developed thematic summaries framed by a realist approach of exploring interventions, their mechanisms, outcomes and how they are shaped by contexts.

Results

Reported outcomes of peer involvement included reduced HIV incidence and prevalence; increased service access, acceptability and quality; changed risk behaviours; and reduced stigma and discrimination. Mechanisms via which these roles work were trust, personal commitment and empathy, using community knowledge and experience, as well as ‘bridge’ and ‘role model’ processes. Contexts of criminalisation, under-resourced health systems, and stigma and discrimination were found to shape these roles, their mechanisms and outcomes. Though contexts and mechanisms are little explored within the literature, we identified a common theme across contexts, mechanisms and outcomes. Peer outreach interventions work through trust, community knowledge and expertise, and ‘bridge’ mechanisms (M) to counter criminalisation and constraining clinic and service delivery environments (C), contributing towards changed drug-using behaviours, increased access, acceptability and quality of harm reduction services and decreased stigma and discrimination (O).

Conclusion

Peer involvement in HIV and harm reduction services in low- and middle-income settings is linked to positive health outcomes, shaped by contexts of criminalisation, stigma, and resource scarcity. However, peer involvement is under-theorised, particularly on how contexts shape mechanisms and ultimately outcomes. Efforts to study peer involvement need to develop theory and methods to evaluate the complex mechanisms and contexts that have influence. Finally, there is a need to expand the range of peer roles, to embrace the capacities and expertise of people who use drugs.

Tuberculosis among economic migrants: a cross-sectional study of the risk of poor treatment outcomes and impact of a treatment adherence intervention among temporary residents in an urban district in Ho Chi Minh City, Viet Nam

BACKGROUND

Tuberculosis (TB) remains a major cause of avoidable deaths. Economic migrants represent a vulnerable population due to their exposure to medical and social risk factors. These factors expose them to higher risks for TB incidence and poor treatment outcomes.

METHODS

This cross-sectional study evaluated WHO-defined TB treatment outcomes among economic migrants in an urban district of Ho Chi Minh City, Viet Nam. We measured the association of a patient's government-defined residency status with treatment success and loss to follow-up categories at baseline and performed a comparative interrupted time series (ITS) analysis to assess the impact of community-based adherence support on treatment outcomes. Key measures of interest of the ITS were the differences in step change (β₆) and post-intervention trend (β₇).

RESULTS

Short-term, inter-province migrants experienced lower treatment success (aRR = 0.95 [95% CI: 0.92-0.99], p = 0.010) and higher loss to follow-up (aOR = 1.98 [95% CI: 1.44-2.72], p < 0.001) than permanent residents. Intra-province migrants were similarly more likely to be lost to follow-up (aOR = 1.86 [95% CI: 1.03-3.36], p = 0.041). There was evidence that patients > 55 years of age (aRR = 0.93 [95% CI: 0.89-0.96], p < 0.001), relapse patients (aRR = 0.89 [95% CI: 0.84-0.94], p < 0.001), and retreatment patients (aRR = 0.62 [95% CI: 0.52-0.75], p < 0.001) had lower treatment success rates. TB/HIV co-infection was also associated with lower treatment success (aRR = 0.77 [95% CI: 0.73-0.82], p < 0.001) and higher loss to follow-up (aOR = 2.18 [95% CI: 1.55-3.06], p < 0.001). The provision of treatment adherence support increased treatment success (IRR(β₆) = 1.07 [95% CI: 1.00, 1.15], p = 0.041) and reduced loss to follow-up (IRR(β₆) = 0.17 [95% CI: 0.04, 0.69], p = 0.013) in the intervention districts. Loss to follow-up continued to decline throughout the post-implementation period (IRR(β₇) = 0.90 [95% CI: 0.83, 0.98], p = 0.019).

CONCLUSIONS

Economic migrants, particularly those crossing provincial borders, have higher risk of poor treatment outcomes and should be prioritized for tailored adherence support. In light of accelerating urbanization in many regions of Asia, implementation trials are needed to inform evidence-based design of strategies for this vulnerable population.

Achieving meaningful participation of people who use drugs and their peer organizations in a strategic research partnership

Background

Peer-led programs with people who use drugs (PWUD) have been a key characteristic of the harm reduction in many countries, including their involvement in research. However, peer involvement in research is often limited to recruitment, consultation, and reporting back, rather than a genuine collaboration in the priority setting, design, and conduct of research. PWUD peer organizations face ongoing challenges to demonstrate the depth of their knowledge of current and emerging issues within drug-using networks and the value of their peer insights for effective research and policy. The identification of benefits, barriers, and enablers for meaningful participation of PWUD in research has often been limited to methodological rather than system level factors.

Methods

This paper draws on the experiences and findings of the What Works and Why (W3) Project, a 5-year collaborative study with peer organizations. The study drew on systems thinking methods to develop a framework to demonstrate the role of peer organizations within their community and policy systems. The study required peer staff and researchers to undertake the simultaneous role of drivers, participants, and analysts in the research. To identify the learnings in relation to meaningful participation of PWUD peer organizations in research, we drew together the insights and experiences of peer staff and researchers across the 5 years of the study

Results

The W3 Project provided insights into the nuances of community-engaged research practice and the ongoing benefits, barriers, and enablers to the meaningful participation of PWUD and their peer organizations. These included system-level barriers and enablers beyond individual research projects or methodology. The capacity of research and peer organizations to maintain meaningful peer participation in research can be restricted or enhanced by the systems in which they are embedded.

Conclusions

Recognizing peer organizations as active participants and drivers within community and policy systems can help clarify their unique and critical role in research. Achieving meaningful collaboration with PWUD peer organizations requires looking beyond good practice methods to the system-level factors with attention to the system-level benefits, barriers, and enablers.

Ability to join the workforce and work productivity among drug users under methadone maintenance treatment in a mountainous area of Northern Vietnam: a cross-sectional study

OBJECTIVES

A major measure of treatment success for drug users undergoing rehabilitation is the ability to enter the workforce and generate income. This study examines the absenteeism and productivity among people who inject drugs (PWID) enrolled in methadone maintenance treatment (MMT) in Northern Vietnam.

SETTING

We conducted a cross-sectional study in two clinics in Tuyen Quang province.

PARTICIPANTS

A total of 241 patients enrolled in MMT.

PRIMARY AND SECONDARY OUTCOME MEASURES

Patients' work productivity was measured using the WPAI-GH instrument (Work Productivity and Activity Impairment Questionnaire: General Health V2.0). We also collected additional characteristics about participants' employment history, such as proficient jobs, whether they actively found a new job and be accepted by employers.

RESULTS

Most of the participants (>90%) were employed at the time of the study. Rates of absenteeism (missed work), presenteeism (impairment while working) and overall loss of productivity were 15.8%, 5.6% and 11.2%, respectively, as measured by the WPAI-GH questionnaire. The most proficient job was 'freelancer' (17.5%), followed by 'blue-collar worker' (10.6%) and 'farmer' (10.2%). Only 26.8% of patients reported that they actively sought jobs in the past. About half of them had been refused by employers because of their drug use history and/or HIV status. We found no statistically significant difference between patients enrolled in MMT for <1 year and those who had been enrolled >1 year. Factors associated with higher work productivity included not endorsing problems in mobility, self-care or pain; being HIV-negative and having greater MMT treatment adherence.

CONCLUSION

Our study highlights the high employment rate and work productivity among PWID in MMT programmes in remote areas of Northern Vietnam. The results can help to improve the quality and structure of MMT programmes across Vietnam and in other countries.

How understanding and application of drug-related legal instruments affects harm reduction interventions in Cambodia: a qualitative study

BACKGROUND

Harm reduction interventions in Cambodia face numerous obstacles because of conflicting understanding and interests and inconsistencies in the implementation by law enforcement officials. This study aims to examine how understanding and application of Drug Control Law (DCL) and Village/Commune Safety Policy (VCSP) affects harm reduction interventions in Cambodia from the standpoints of law enforcement officials, people who inject drugs and people who use drugs (PWID/PWUD), as well as other key stakeholders.

METHODS

This qualitative study was conducted in the capital city of Phnom Penh in 2015. We held five focus group discussions (FGDs) with groups of PWID/PWUD, police officers, Sangkat/commune officers, and local non-governmental organization (NGO) field staff. We also conducted ten key informant interviews (KIIs) with representatives from government agencies, donor agencies, and NGOs. FGDs and KIIs with Cambodian participants were transcribed in Khmer and translated into English. KIIs with foreign participants were transcribed in English. Transcripts were read and re-read to identify emerging themes, which were reviewed and refined to develop common and divergent patterns.

RESULTS

There was a huge gap between what the DCL and VCSP say and how law enforcement officers and PWID/PWUD understood them. The gap was also evident in how law enforcement officers implemented the DCL and VCSP. Harm reduction services, including health- and non-health-related interventions, were limited and challenged by unsupportive attitudes, misinterpretation of the DCL and VCSP, and the lack of full engagement with NGOs in the development of these instruments. The needs of PWID/PWUD in accessing health care services were not met due to misconduct of authorities while practicing the DCL and VCSP. Further, the misconduct and enforcement of the law and policy lead to increased social discrimination and physical abuses against PWID/PWUD.

CONCLUSIONS

There is a lack of common understanding of the drug-related law and policy and their implications to harm reduction services among both law enforcement officers and PWID/PWUD. Thus, there is a need to mainstream and simplify the law and policy for better comprehension among these actors. To improve the quality and coverage of harm reduction interventions, the gap of understanding and enforcement of laws and policies should be narrowed, and coordination between the government and NGOs and other key stakeholders should be strengthened.
