Brief Summary

Pneumonia is a common pathology with significant morbidity and mortality. It is recommended in his diagnostic approach to perform either a chest X-ray or a pleuropulmonary ultrasound. Previous studies have shown the advantages of ultrasound in terms of diagnostic performance cost and patient irradiation. However, it remains little used in clinical practice.

Conditions

Pneumonia

Keywords

Pneumonia; Pleuropulmonary ultrasound; Antibiotic

Outcome Measures

Primary Outcomes (1)

• Time between the antibiotic prescription and the pleuropulmonary ultrasonography used to detect pneumonia

  Time between the antibiotic prescription and the pleuropulmonary ultrasonography used to detect pneumonia

  1 hour

Secondary Outcomes (4)

• Calculation of the predictive values of the pleuropulmonary ultrasound for pneumonia diagnosis

  1 day

• duration of performing the pleuropulmonary ultrasound

  5 minutes

• Time between the patient's admission to the emergency department and the completion of the pleuropulmonary ultrasound

  1 hour

• 4. Time between the performance of the pleuropulmonary ultrasound and the performance of the chest X-ray

  2 hours

Study Arms (1)

Patient admitted for suspicion of Pneumonia

Patient admitted in emergency department of Grenoble Alpes University Hospital for suspicion of Pneumonia

Procedure: Pleuropulmonary ultrasound performed by the investigator for patient with suspicion od Pneumonia

Interventions

Pleuropulmonary ultrasound performed by the investigator for patient with suspicion od Pneumonia PROCEDURE

In addition to the traditional management done by the physician at the patient's expense (such as clinical examination and paraclinical examinations like biology, chest X-ray, etc.), the investigator will perform pleuropulmonary ultrasound.

Patient admitted for suspicion of Pneumonia
