Injecting behaviour and risky needle use amongst methadone maintenance clients

Area of Science:

• Addiction Medicine
• Public Health
• Infectious Disease Epidemiology

Background:

• Methadone maintenance treatment (MMT) is a cornerstone for opioid use disorder.
• Injecting drug use remains a significant risk factor for HIV transmission.
• Understanding risk behaviors within MMT populations is crucial for targeted interventions.

Purpose of the Study:

• To investigate injecting behaviors and risky needle use among methadone maintenance clients.
• To identify characteristics associated with risky injecting practices.
• To assess the impact of knowledge on HIV prevention among injectors.

Main Methods:

• Survey of 193 methadone maintenance clients.
• Comparison of injectors versus non-injectors.
• Analysis of risky versus safe injecting practices based on HIV transmission guidelines.
• Assessment of drug use severity, legal problems, employment, and HIV knowledge.

Main Results:

• 116 clients (60%) reported injecting drugs in the past month.
• Injectors were younger, had shorter MMT duration, lower doses, and more severe problems.
• Risky injectors were more likely unemployed and had less knowledge of HIV prevention compared to safe injectors.
• Risky injecting practices were defined as contravening HIV transmission minimization guidelines.

Conclusions:

• Enhancing MMT programs with adequate dosing and retention can reduce HIV transmission.
• Improving client knowledge of safe injecting practices and needle cleaning is essential.
• Targeted education on differentiating safe from risky injection behaviors is needed.
