Official title
Patient Decision Aid for Medication-Assisted Treatment for Opioid Use Disorder
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aim of the study is to test the effectiveness of the Patient Decision Aid for Opioid Use Disorder (PtDA-MAT) by conducting a stepped-wedge cluster-randomized trial in CA H\&SS (stratified by rural vs. non-rural areas) for adults with OUD. Patient outcomes will be tracked by (1) personal assessments (baseline, 3 months, and 6 months): drug use, overdose, healthcare utilization, and (2) clinical and administrative records (over approximately 24 months): drug treatment status and retention, physical and mental health diagnoses, arrest, incarceration, controlled substance use, and mortality. Multilevel models will be applied to test the intervention effects, controlling for possible temporal trends.
