Community-Acquired Pneumonia Diagnosis Using Lung Ultrasound in Emergency Room Adults
A study testing Lung Ultrasound (LUS) and Chest radiography (CR) in people with Community-acquired Pneumonia, run by Centre Hospitalier Universitaire de Nice at 1 site in Monaco.
Trial summary
Community-Acquired Pneumonia (CAP) is a major problem in Emergency Department (ED). Diagnosis relies on combination of clinical symptoms and results of chest radiography (CR). Patients' management (treatment, support) depends on delay and quality of the diagnosis. Read more about this study

About this study
Official title: Accuracy of Lung Ultrasound for the Diagnosis of Community-Acquired Pneumonia in Emergency Room Patients
Community-Acquired Pneumonia (CAP) is a major problem in Emergency Department (ED). Diagnosis relies on combination of clinical symptoms and results of chest radiography (CR). Patients' management (treatment, support) depends on delay and quality of the diagnosis. However, signs and symptoms are highly aspecific and interpretation of CR is subject to frequent discrepancies. Then diagnosis of CAP may be uncertain; therefore, overdiagnosis is frequent and leads to over-use of antimicrobial therapy; missing diagnosis is also deleterious and delays adequate treatment including antibiotics. CT scan completes CR and helps clinician making properly diagnosis of CAP; obtaining CT in a 4-hour time-lapse allows better diagnosis and management as accurate as an independent expert adjudication committee does. However availability of CT as well as radiation interrogates on the benefit that Lung Ultrasounds (LUS) may have in diagnosis strategy of suspected CAP. LUS is a noninvasive easy-to-use device whose practice is widely endorsed worldwide by emergency medicine associations and societies. Additionally, previous studies advocate for the use of LUS for diagnosis of CAP in the ED. Therefore the Promotor developed a study to compare LUS and CR as a primary imaging for diagnosis of CAP at the ED.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lung Ultrasound (LUS)Diagnostic test
Lung Ultrasound : Ultrasound is a medical imaging technique that relies on the use of ultrasound, inaudible sound waves, which allow to "visualize" lungs.
Chest radiography (CR)Diagnostic test
The chest X-ray is a medical imaging examination that provides images of the lungs through the X-ray pulse.
| Study group | Role | What they receive |
|---|---|---|
| CR + LUS | Other | Patient will be performed first the Chest radiography then the Lung ultrasound. Receives: Diagnostic Test: Lung Ultrasound (LUS); Diagnostic Test: Chest radiography (CR) |
| LUS + CR | Other | Patient will be performed first the Lung ultrasound then the Chest radiography Receives: Diagnostic Test: Lung Ultrasound (LUS); Diagnostic Test: Chest radiography (CR) |
What is being measured
The primary outcome is the main question the study is designed to answer.
The sensitivity of lung ultrasound (LUS) and chest X-ray (CR) to detect community-acquired pneumonia (CAP) will be mesured and compared in patients visiting the emergency department for suspected CAP
Measured: Within the day of inclusion
Secondary outcomes (4)
specificity, positive predictive value and negative predictive value : indicators of diagnosis performance, will be measured and compared as a primary imaging for diagnosis of CAP
Measured: Within the day of inclusion
Specificity, positive predictive value, negative predictive value will be measured and compared in each sequence of imaging (CR + LUS and LUS + CR) for CAP detection
Measured: Within the day of inclusion
medical decisions for diagnosis of CAP after each step LUS then CR or CR then LUS and after low dose CT6scan (CT) will be compared to the medical decisions of the adjudication committee
Measured: Up to 6 months
The concordance of interpretation (for CR and CT) between attending radiologist and expert radiologist of the adjudication committee (gold standard) wil be studied.
Measured: Up to 6 months

What does the primary outcome measure?
The sensitivity of lung ultrasound (LUS) and chest X-ray (CR) to detect community-acquired pneumonia (CAP) will be mesured and compared in patients visiting the emergency department for suspected CAP (time frame: Within the day of inclusion). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04210102, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Dec 2025; AzTrials last refreshed its copy on 26 Oct 2026.
