Smartphone Based Interventions for Opioid Use Disorder A Systematic Review of Engagement, Retention, and Efficacy
Back to course
Pdf Summary
This systematic review examined 22 studies published from 2018 to 2025 on smartphone-based interventions for opioid use disorder (OUD), focusing on user engagement, treatment retention, and clinical efficacy. The growing use of digital tools aims to supplement standard OUD therapies by enhancing access and support, yet their effectiveness and long-term impact remain uncertain.<br /><br />The review included six randomized controlled trials and 16 observational or pilot studies involving adults with OUD. Key app features that promoted engagement included interactive cognitive-behavioral therapy (CBT) modules, daily self-monitoring, and contingency management. Median daily app use ranged from two to six sessions. Notably, nine out of eleven studies comparing retention found better 12-week retention rates among app users (56% to 84%) compared to control groups (34% to 63%). Moreover, twelve studies reported reductions in opioid use, often verified by urine toxicology; moderate treatment effects were particularly evident in interventions combining smartphone apps with medication-assisted treatment (MAT), especially buprenorphine.<br /><br />Despite promising short-term results, the evidence base is limited by inconsistent outcome measures and scarcity of long-term data, restricting broad clinical integration. The review calls for standardized metrics and extended follow-up to clarify the role of smartphone tools in OUD care.<br /><br />Scientifically, this review highlights the potential for smartphone interventions to improve engagement and retention alongside MAT in OUD treatment. By identifying effective app components, it supports the growing field of digital therapeutics in addiction psychiatry. However, stronger and more consistent evidence is needed to fully realize and implement these technologies in clinical practice.
