Opioid use disorder (OUD) remains a major public health challenge in the United States, affecting more than six million Americans and contributing to high rates of overdose-related deaths. Although medications for opioid use disorder (MOUD), including buprenorphine, methadone, and naltrexone, are effective in reducing cravings, overdoses, and mortality, retention in treatment remains a persistent challenge. Through participation in the AIM-AHEAD Consortium Development Program, Dr. Yanmin Gong has explored how artificial intelligence and machine learning (AI/ML) methods can be used to better understand factors associated with buprenorphine treatment retention and discontinuation.
Study Design and Methods
Dr. Gong’s research draws on multiple national datasets to examine treatment retention among individuals receiving buprenorphine for OUD. One study used reimbursement claims data from IQVIA prescription records spanning 2006 to 2022 and focused on adults receiving buprenorphine treatment. Predictors included provider availability, mental health services, demographics, psychiatric diagnoses, healthcare utilization, and measures of social vulnerability. Statistical analyses incorporated multinomial logistic regression and stepwise model selection approaches to evaluate treatment duration across patient populations.
Additional analyses applied machine learning methods to examine patterns of treatment discontinuation across demographic, insurance, regional, and community-level factors. These approaches included classification models, regression methods, decision trees, and neural networks. Further work used state-level treatment discharge data from SAMHSA’s Treatment Episode Data Set – Discharges (TEDS-D) to develop multi-task learning models designed to identify both shared and state-specific patterns in MOUD dropout risk.
The research also evaluated fairness across several AI models used to predict treatment retention and premature discontinuation, including approaches intended to reduce performance differences across patient groups.
Key Findings
Across studies, analyses identified variation in treatment retention associated with insurance status, mental health service utilization, age, and community-level social vulnerability. Early medication adherence during the first months of treatment was also identified as an important predictor of long-term retention.
The work further highlighted geographic variation in MOUD access and treatment outcomes across states, reflecting differences in healthcare infrastructure, non-medical health factors, and state-level policies. Multi-task learning approaches achieved stronger predictive performance than both independent state-level models and pooled national models.
Fairness analyses additionally identified differences in model performance across patient populations. Several AI models showed variation in their predictions across demographic groups, including differences in treatment discontinuation and long-term retention estimates. Approaches designed to reduce performance variation across groups improved consistency in some cases, highlighting the importance of continued evaluation of AI models used in MOUD research.
Implications for Research and Clinical Practice
By integrating national claims data, state-level treatment records, and AI/ML approaches, this work contributes to broader efforts to better understand factors associated with MOUD retention and discontinuation. The findings also support ongoing research into how predictive models may be used to examine regional variation, subgroup differences, and treatment-related outcomes in opioid use disorder care.
This research further highlights the importance of evaluating fairness and explainability in healthcare AI applications, particularly when predictive models are applied across varying patient populations.
Recognition and Next Steps
Dr. Gong’s work has resulted in three publications accepted for presentation at leading health informatics and information systems conferences, including CHASE 2025, CHITA 2025, and ICIS 2025. An additional three manuscripts are currently under review at peer-reviewed journals, including the Journal of the American Medical Informatics Association (JAMIA) and JAMA Network Open. Ongoing efforts continue to examine AI/ML approaches for understanding treatment retention, discontinuation, and variation in opioid use disorder care.
