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 Results may not be published yet.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.

Summary

Researchers at the University of Southern Denmark compare how much staff time two chest imaging methods require when adults arrive at the emergency department with suspected community-acquired pneumonia. One method is conventional chest radiography, the other is ultra-low-dose chest computed tomography. The study measures cumulative staff person-minutes per imaging episode, from when staff fetch the patient to when a final radiological report is ready. About 66 adults who can undergo the assigned scan take part during weekday daytime hours.

What this could mean

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

Active substance
ultra-low-dose chest computed tomography (ULDCT) compared with conventional chest radiography
What this could lead to
If ultra-low-dose CT uses staff time efficiently, hospitals could weigh it against chest X-rays when planning emergency imaging for suspected pneumonia.
What could go wrong
This small study measures staff time, not whether patients get better or are diagnosed more accurately. Its results may not apply to hospitals with different staffing or equipment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients presenting to the emergency department during daytime weekday hours in whom CAP is a differential diagnosis, and who are able to undergo the assigned imaging examination. Exclusion Criteria: * Patients requiring immediate imaging for a critical condition (for example suspected pneumothorax). * Bariatric patients exceeding the technical limits of the scanner * Pregnancy * Patients requiring additional imaging beyond the chest (for example abdominal CT) * Severe dementia, or need for sedation to complete imaging * Patients requiring mechanical ventilation. * Patients requiring accompaniment by medical staff during transport
