Summary

This trial tests whether an AI chatbot called MICA, combined with weekly text reminders, can help emergency department patients reduce risky alcohol use. About 750 adults who report heavy drinking will be randomly assigned to use MICA or receive usual care. The study tracks how much they drink over time to see if the digital approach works.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
AI chatbot (MICA) and weekly SMS check-ins
What this could lead to
If it works, this could offer a scalable, low-cost digital tool to help people cut back on risky drinking without needing a therapist.
What could go wrong
This is an early-stage trial with no phase, so results are uncertain. The AI may not engage users effectively, and self-reported drinking data can be unreliable.

This is an AI summary of the original study and may miss details. Read our disclaimer.
