Drug-related harm among people who inject drugs in Thailand: summary findings from the Mitsampan Community Research Project

Transition from nonmedical prescribed opioids to non-injection heroin use among young integrated Thai male users in Bangkok

Opioid use and misuse are understudied in Thailand despite evidence suggesting that a portion of young Thai male integrated drug users are initiating use of non-medical prescribed opioids with some transitioning to heroin. This study aims to capture and analyze the individual and social factors influencing these transitions. Twenty in-depth semi-structured interviews were conducted between December 2019 and January 2020 in the Bangkok metropolitan area with young male opioid users who transitioned to heroin. Sixteen respondents initiated opioid through a Tramadol cocktail named "YaPro" and tended to transition to heroin use within 21 months. The interaction of specific social and individual factors such as joining recreational activities, curiosity or experimentation gradually modified the opioid-related meanings, attitude and practices of Thai users, who ultimately transition to heroin use. These results indicate that drug prevention programs in Thailand should encompass young opioid users in their intervention and further research need to focus on nonmedical use of prescription opioids in Thailand.

HIV and the criminalisation of drug use among people who inject drugs: a systematic review

BACKGROUND

Mounting evidence suggests that laws and policies prohibiting illegal drug use could have a central role in shaping health outcomes among people who inject drugs (PWID). To date, no systematic review has characterised the influence of laws and legal frameworks prohibiting drug use on HIV prevention and treatment.

METHODS

Consistent with PRISMA guidelines, we did a systematic review of peer-reviewed scientific evidence describing the association between criminalisation of drug use and HIV prevention and treatment-related outcomes among PWID. We searched MEDLINE, Embase, SCOPUS, PsycINFO, Sociological Abstracts, CINAHL, Web of Science, and other sources. To be included in our review, a study had to meet the following eligibility criteria: be published in a peer-reviewed journal or presented as a peer-reviewed abstract at a scientific conference; examine, through any study design, the association between an a-priori set of indicators related to the criminalisation of drugs and HIV prevention or treatment among PWID; provide sufficient details on the methods followed to allow critical assessment of quality; be published or presented between Jan 1, 2006, and Dec 31, 2014; and be published in the English language.

FINDINGS

We identified 106 eligible studies comprising 29 longitudinal, 49 cross-sectional, 22 qualitative, two mixed methods, four mathematical modelling studies, and no randomised controlled trials. 120 criminalisation indicators were identified (range 1-3 per study) and 150 HIV indicators were identified (1-5 per study). The most common criminalisation indicators were incarceration (n=38) and street-level policing (n=39), while the most frequent HIV prevention and treatment indicators were syringe sharing (n=35) and prevalence of HIV infection among PWID (n=28). Among the 106 studies included in this review, 85 (80%) suggested that drug criminalisation has a negative effect on HIV prevention and treatment, 10 (9%) suggested no association, five (5%) suggested a beneficial effect, one (1%) suggested both beneficial and negative effects, and five (5%) suggested both null and negative effects.

INTERPRETATION

These data confirm that criminalisation of drug use has a negative effect on HIV prevention and treatment. Our results provide an objective evidence base to support numerous international policy initiatives to reform legal and policy frameworks criminalising drug use.

Seeing through the public health smoke-screen in drug policy

In deliberations on drug policy in United Nations fora, a consensus has emerged that drug use and drug dependence should be treated primarily as public health concerns rather than as crimes. But what some member states mean by "public health approach" merits scrutiny. Some governments that espouse treating people who use drugs as "patients, not criminals" still subject them to prison-like detention in the name of drug-dependence treatment or otherwise do not take measures to provide scientifically sound treatment and humane social support to those who need them. Even drug treatment courts, which the U.S. and other countries hold up as examples of a public health approach to drug dependence, can serve rather to tighten the hold of the criminal justice sector on concerns that should be addressed in the health sector. The political popularity of demonisation of drugs and visibly repressive approaches is an obvious challenge to leadership for truly health-oriented drug control. This commentary offers some thoughts for judging whether a public health approach is worthy of the name and cautions drug policy reformers not to rely on facile commitments to health approaches that are largely rhetorical or that mask policies and activities not in keeping with good public health practise.

Effectiveness of the behavior change intervention to improve harm reduction self-efficacy among people who inject drugs in Thailand

BACKGROUND

People who inject drugs (PWID) in Thailand reported unsafe injection practices resulting in injection-related health consequences. Harm reduction self-efficacy plays an important role and could be improved to reduce harm associated with injecting drugs. Evidence-based interventions targeting PWID are needed. This study sought to evaluate the effectiveness of the behavior change intervention within the PWID population.

METHODS

The behavior change intervention, Triple-S, was designed to improve harm reduction self-efficacy among PWID. This quasi-experimental study was a pre- and post-comparison with a control group design. Participants were PWID, aged 18-45 years, and located in Bangkok. Changes in harm reduction self-efficacy of the intervention group were compared with the control group using paired and independent t-test.

RESULTS

Most of PWID were male (84%), had a secondary school and lower education (71%), were single, and had a mean age of 41 years. They had been injecting drugs for an average of 20 years, and the median of drug injections per week was ten times in the past month. Pre- and post-intervention effects were measured and results showed that the intervention group reported improvement in harm reduction self-efficacy in negative emotional conditions (P=0.048).

CONCLUSION

Our findings suggest that Triple-S intervention can significantly improve harm reduction self-efficacy in negative emotional conditions. The results may suggest the importance of behavior change intervention, especially when integrated with services provided by drop-in centers. The intervention can be further developed to cover other harm reduction behaviors and improve harm reduction self-efficacy.

From conflict to partnership: growing collaboration between police and NGOs in countries with concentrated epidemics among key populations

Introduction

Between September 2012 and December 2015, a series of national and regional consultations, aimed at resolving a persistent dynamic of conflict between law enforcement agencies (LEAs) and civil society organizations (CSOs) working on issues of access to HIV services in high-priority countries for people who use drugs have been organized by the HIV/AIDS Section of the United Nations Office on Drugs and Crime, the Joint United Nations Programme on HIV/AIDS, the Law Enforcement and HIV Network (LEAHN) and other international organizations. The aim of these consultations has been to understand, at a national and regional level, the key points of tension between police and CSOs and how to overcome these tensions to enhance access to and uptake of services by key populations, including people who inject drugs, sex workers, men who have sex with men and transgenders. This commentary briefly describes the methods, process, content and key outcomes of these consultations held across diverse number of countries and regions, including Africa, South East Asia, South Asia, Central Asia, Eastern Europe and Latin America.

Discussion

While the context varies, this paper highlights that there are commonalities that drive a persistent dynamic of conflict and therefore also common methods for resolution of conflict and forging partnerships. Both policing and CSOs have key sectoral responsibilities and reform agendas to implement to ensure that as an individual agency they are able to meet their obligations as partners in the HIV response. Using the key outcomes of discussions and recommendations from these consultations and drawing on existing literature, the objective of this paper is to present a preliminary model that roadmaps the critical path from resolution of conflict to partnership between LEAs and CSOs.

Conclusions

This paper seeks to highlight that critical resources are required to support ongoing development and harnessing of partnerships between LEAs and CSOs and argues that these resources should not just come from global HIV funding mechanisms but should be part of a more mainstreamed security sector reform agenda that understands the mutual benefits that programming for human rights–based policing reform would have on HIV, development and security.

High prevalence of syringe lending among HIV-positive people who inject drugs in Bangkok, Thailand

Background

Syringe sharing continues to be a major driver of the HIV pandemic. In light of efforts to enhance access to sterile syringes and promote secondary prevention among HIV-positive individuals, we sought to identify the prevalence and correlates of used syringe lending among self-reported HIV-positive people who inject drugs (PWID) in Bangkok, Thailand.

Findings

We used bivariable statistics to examine factors associated with self-reported syringe lending among self-reported HIV-positive PWID participating in the Mitsampan Community Research Project, a serial cross-sectional study of PWID in Bangkok, between June 2009 and October 2011. In total, 127 individuals were eligible for this analysis, including 25 (19.7 %) women. Twenty-one (16.5 %) participants reported syringe lending in the prior 6 months. Factors significantly associated with syringe lending included daily methamphetamine injection (odds ratio (OR) = 10.2, 95 % CI, 2.1–53.6), daily midazolam injection (OR = 3.1, 95 % CI, 1.1–8.7), use of drugs in combination (OR = 4.5, 95 % CI, 1.0–41.6), injecting with others on a frequent basis (OR = 4.25, 95 % CI, 1.3–18.3), and not receiving antiretroviral therapy (OR = 2.9, 95 % CI, 1.1–7.9).

Conclusions

A high prevalence of syringe lending was observed among self-reported HIV-positive PWID in Bangkok, which was associated with high intensity drug use, polysubstance use, and frequently injecting with others. It is particularly concerning that individuals who lent syringes were more likely to be untreated for HIV disease given the known benefits of antiretroviral provision on the prevention of HIV transmission. These findings underscore the need to expand access to sterile syringes and HIV treatment among HIV-positive PWID in Thailand.

Perceived barriers to utilise methadone maintenance therapy among male injection drug users in rural areas of southern Thailand

INTRODUCTION AND AIMS

Methadone maintenance therapy (MMT) has been proven to be effective and cost-effective in treating dependence on opioids. However, concerns remain that geographical, financial and other hidden barriers may hinder access to MMT, especially in rural areas where health services are limited. The objective of this study was to determine factors associated with utilisation of MMT by injection drug users (IDUs) living in Songkhla province.

DESIGN AND METHODS

A cross-sectional study among 159 IDUs in Songkhla province of southern Thailand was conducted. Participants were recruited using a snowball technique. Data were collected from July 2013 to January 2014 via face-to-face interviews.

RESULTS

Around one-forth (24.5%) of participants had difficulties travelling to MMT clinics because of the long distance, long travelling time and lack of a private vehicle. Twenty-four percent faced difficulties with the clinic's opening hours and 28% faced difficulties paying for the cost of travel. IDUs who utilised the MMT perceived risks of injection drug use differently compared with those who did not. Younger or Muslim IDUs were less likely to attend MMT. IDUs who perceived that MMT was effective were more likely to utilise MMT.

DISCUSSION AND CONCLUSIONS

Physical accessibility, affordability and acceptability play an essential role in MMT utilisation. Developing alternatives that reduce the travelling time, costs for IDUs and more convenient operation hours to suit their lifestyles may increase the utilisation of MMT. Intensive consultation before starting MMT is highly recommended.
