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 Results may not be published yet.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

Summary

After surgery, many older adults experience confusion or memory problems, known as delirium. This study tests a program that identifies patients at high risk before surgery and then uses simple steps—like better sleep and hydration—to prevent delirium. The program also educates families and alerts the care team. Researchers will compare how often delirium occurs before and after the program is put in place.

What this could mean

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

Active substance
multicomponent delirium-risk prevention bundle (education, chart flagging, nursing protocols)
What this could lead to
If it works, this program could become a standard way to prevent postoperative confusion in older surgical patients, making surgery safer.
What could go wrong
This is a single-center study with 260 participants, so results may not apply everywhere. The program relies on staff following new steps, which can be hard to maintain.

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Dec 2025

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.

Ages

60 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
