What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This trial tests whether an AI-powered smartphone app can help patients prepare better for colonoscopy. The app provides videos, text, and chatbot support to guide patients through the bowel preparation process. Researchers compare this approach to standard written and verbal instructions from nurses. The goal is to see if the app improves bowel cleanliness, patient understanding, and satisfaction.

What this could mean

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

Active substance
An AI-integrated smartphone application that provides multimodal education, including visual and textual information, videos, and chatbot dialogues, to guide patients through bowel preparation before colonoscopy.
What this could lead to
If effective, this AI app could become a standard tool to improve bowel cleanliness, increase polyp detection, and reduce the burden on nursing staff.
What could go wrong
The trial is small and early, and the app's success depends on patient engagement and technical reliability. It may not outperform traditional education in all settings.
