Aims: Untreated opioid use disorder (OUD) is associated with overdose, premature death and infectious disease, including human immunodeficiency virus (HIV) and Hepatitis C (HCV). While prior studies have shown that educational interventions are associated with improvements in HIV and HCV knowledge and reductions in risk behaviors, those examined to date have typically been time- and resource-intensive. We recently developed an HIV+HCV Education intervention which aims to improve HIV and HCV knowledge in a single visit using an automated iPad platform. In this project, we examined its ability, using a within-subject evaluation, to improve knowledge of HIV and HCV transmission and risks among adults with OUD.
Methods: Participants were 25 adults with OUD who were enrolled in a 12-week randomized trial evaluating the efficacy of an Interim Buprenorphine Treatment (IBT) for reducing illicit opioid use while awaiting entry into community-based opioid treatment. Participants completed a baseline HIV+HCV knowledge assessment (Pre-Test) followed by corrective feedback, both administered via iPad. They then completed an interactive HIV flipbook and animated HCV video, also on iPad, followed by a second administration of the knowledge assessment (Post-Test). Finally, to evaluate whether any changes in knowledge persisted over time, the HIV+HCV assessment was administered again at 4 and 12 weeks following study intake.
Results: At baseline (Pre-Test), participants answered 69% and 65% of items correctly on the HIV and HCV assessments, respectively. After completing the educational intervention, participants answered 86% of items correctly on both the HIV and HCV assessments (p’s<.001). These improvements in knowledge also persisted throughout the three-month study, with scores at Week 4 and 12 timepoints significantly greater than baseline (p’s<.001).
Conclusion: An HIV+Hepatitis Education intervention delivered via a portable, automated iPad platform may produce significant and persistent improvements in HIV and HCV knowledge among adults with OUD. These data provide additional support for the use of mobile educational interventions for enhancing HIV and HCV knowledge in individuals at elevated risk for infectious disease.
Support: This trial was supported by NIDA R34 DA3730385 (Sigmon) with additional support by NIDA T32 DA007242 (Higgins).
