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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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

This study looks at whether four common risk-scoring tools — POSSUM, P-POSSUM, the Clinical Frailty Scale, and the Charlson Comorbidity Index — can accurately predict complications and death within 30 days after abdominal surgery. Researchers will collect data from 350 adults undergoing scheduled or emergency gastrointestinal surgery and compare the scores to actual outcomes. The goal is to see if these tools help identify high-risk patients and improve surgical planning.

What this could mean

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

What this could lead to
If the risk scales prove accurate, surgeons could better identify high-risk patients and tailor care to reduce complications.
What could go wrong
This is an observational study, not a treatment trial. The scales may not predict outcomes better than standard clinical judgment.

Who can take part

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

Who is studied

A prospective observational study will be carried out in which all patients undergoing gastrointestinal surgery will be included, both scheduled and urgently. At 30 days postoperatively, the clinical records of the patients will be reviewed in order to establish the incidence of morbidity and mortality.
