Chest X-ray vs ultra-low-dose chest CT in adults with possible pneumonia in the ER
Official title: Human-Resource Utilisation of Conventional Chest Radiography Versus Ultra-Low-Dose Chest Computed Tomography for Suspected Community-Acquired Pneumonia in Adults in the Emergency Department
Run by University of Southern Denmark · NCT07870525 · Data updated 2026-11-12
This study tests whether an ultra-low-dose chest CT can replace chest X-ray for adults in the emergency department when pneumonia is a possibility, to see if it changes how much staff time is spent on imaging.

Is this trial a fit for you?
✓Likely a good fit
Adults presenting to the ED with CAP as a differential diagnosis who can safely undergo the assigned imaging test.
✕Probably not a fit
Patients needing immediate imaging for critical conditions or meeting one or more exclusion criteria may not benefit from this approach.

What this trial studies
In adults presenting to the emergency department with suspected community-acquired pneumonia, researchers compare total staff time spent per imaging episode between standard chest radiography and ultra-low-dose CT. The study is a single-center, two-period observational time-and-motion analysis at Hospital Sønderjylland in Aabenraa. CXR data are collected from 2025 through mid-2027, while the ULDCT arm begins in late 2026, with the main outcome being staff minutes per imaging episode computed from radiology timestamps and in-room time. Analyses include nonparametric comparison and bootstrapped confidence intervals, with adjustments via quantile regression. The goal is to understand workflow impact of substituting ULDCT for CXR in the ED for potential CAP cases.
Why it matters
Potential benefit: If ULDCT reduces staff time without compromising care, it could streamline ED imaging workflows.
How similar studies have gone: Previous work suggests higher diagnostic accuracy with ULDCT, but data on workflow time impact are limited or mixed.

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
