A brief intervention for hazardous drinkers in a needle exchange program.

Area of Science:

• Public Health
• Addiction Medicine
• Infectious Disease Epidemiology

Background:

• Active injection drug users (IDUs) with hazardous alcohol use face elevated HIV transmission risks, primarily through sharing injection equipment.
• Needle exchange programs are critical points for intervention among high-risk populations.

Purpose of the Study:

• To evaluate the effectiveness of a brief motivational intervention (MI) in reducing injection-related HIV risk behaviors (IRRB) among AUDIT-positive IDUs.
• To assess the impact of MI on the frequency of sharing injection equipment.

Main Methods:

• A randomized clinical trial was conducted with 109 AUDIT-positive injectors recruited from a needle exchange program.
• Injection-related HIV risk behavior was measured using the 30-day Timeline Followback Method to quantify days of sharing injection equipment.
• Subjects were randomized to receive either a brief motivational intervention or a control condition.

Main Results:

• The study observed a significant mean reduction of 9.1 days in IRRB from baseline to 6-month follow-up (p <.001).
• A trend towards zero IRRB days at follow-up was noted for the MI group compared to controls (OR = 2.1; 95% CI = 0.9-4.5).
• Significant reductions in IRRB were observed across various improvement thresholds, supporting the intervention's efficacy.

Conclusions:

• Brief motivational intervention effectively reduces drug-related HIV risk behaviors among active injection drug users.
• MI can serve as a valuable supplementary tool for existing harm reduction services aimed at mitigating HIV transmission.
• Targeting hazardous alcohol users within the IDU population is crucial for effective HIV prevention strategies.
