Changes in supervised drug-injecting practices following a community-based educational intervention: A longitudinal analysis

Abstract

BackgroundPeople who inject drugs face several health issues because of unsafe injecting practices. We aimed to evaluate changes in supervised drug-injecting practices following the implementation of a face-to-face educational intervention. MethodsThe national study ANRS-AERLI was conducted in 17 harm reduction (HR) facilities in France between 2011 and 2013. Eight offered the intervention and nine did not. We conducted a pre-post analysis focusing on injecting practices data, collected in the 8 HR facilities providing the intervention. The intervention consisted of providing face-to-face educational sessions including direct observation of injecting practices, counseling about safer injecting, and shared discussion. Injecting practices were collected following a checklist and classified as safe or unsafe. To assess changes in injecting practices, practices were compared before (at baseline) and after at least one educational session. FindingsMixed logistic models showed that the 78 participants included were more likely to improve in the following drug-use steps: setting up a clean preparation area (Adjusted Odds Ratio (AOR) = 3.4, 95% Confidence Interval (95% CI) = 1.6–7.6), hand washing (AOR = 7.2, 95% CI = 3.1–16.4), skin cleaning (AOR = 5.6, 95% CI = 2.5–12.1), choice of safe injection site (AOR = 6.5, 95% CI = 1.5–28.8) and post-injection bleeding management (AOR = 12.8, 95% CI = 5.5–29.9). Furthermore, participants were less likely to lick their needles before injecting (AOR = 8.1, 95% CI = 1.5–43.4) and to perform booting/flushing (AOR = 2.5, 95% CI = 1.2–5.3). ConclusionsThe AERLI intervention seems to be effective in increasing safe drug-injecting practices.
