Clinical 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. 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.

Intervention

Diagnostic Test:
• Lung Ultrasound (LUS)
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)
The chest X-ray is a medical imaging examination that provides images of the lungs through the X-ray pulse.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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		Within the day of inclusion
Secondary	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		Within the day of inclusion
Secondary	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		Within the day of inclusion
Secondary	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		Up to 6 months
Secondary	The concordance of interpretation (for CR and CT) between attending radiologist and expert radiologist of the adjudication committee (gold standard) wil be studied.		Up to 6 months
