What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are testing whether a smartphone app powered by artificial intelligence helps hospitalized adults prepare their bowels better before a colonoscopy. Half of the 140 participants receive standard written and verbal instructions, while the other half also use an AI app on the LINE platform that offers structured lessons, answers questions, recognizes food photos, analyzes stool photos, and gives personalized feedback. The main measure is how clean the bowel looks during the colonoscopy, rated by the doctor using the Aronchick Scale. The study also looks at patients' knowledge and satisfaction with the education they receive.

What this could mean

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

Active substance
a smartphone app that uses artificial intelligence to coach patients through bowel preparation for colonoscopy
What this could lead to
If it works, hospitals could use AI coaching apps to help patients prepare better for colonoscopy, which may make the exam more accurate and reduce the need to repeat it.
What could go wrong
This is a single-center study of 140 hospitalized adults, so results may not apply to other patients or settings. An app cannot fix preparation problems caused by medical conditions or poor tolerance of the cleansing drink.

Expected to finish

Jan 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
