Study summary

The goal of this clinical trial is to learn if/how an AI chatbot can support patients who in recovery for substance use, specifically those who are receiving medication for opioid use disorder.

Can the chatbot help lower drug use? Can the chatbot help improve clinical appointment adherence? Can the chatbot help patients build self-efficacy in leading their own recovery journey? Will the chatbot help reduce workload burden for primary care teams? Can the chatbot serve as a safe, useful and engaging tool to support patients?

Researchers will investigate the effects of using a chatbot to support follow-up care for patients in opioid use recovery.

Participants will:

  • Receive access to a chatbot for 12 weeks that they can use to prepare for upcoming clinical appointments, find community resources, learn about urge-surfing and wellness techniques, and query for assistance with other recovery-related information and tasks
  • Complete surveys and provide user feedback
