Pilot Study to Study the Time Between Pleuropulmonary Ultrasound and Antibiotic Therapy Prescription in Patients Admitted to the Emergency Department for Suspected Pneumonia

Pilot Study to Study the Time Between Pleuropulmonary Ultrasound and Antibiotic Therapy Prescription in Patients Admitted to the Emergency Department for Suspected Pneumonia

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.

The study will be conducted in the Emergency Department of grenoble University Hospital.

Patient admitted to the emergency department for respiratory symptoms (cough, fever, and/or dyspnea) will be enrolled in the study according to the inclusion and non-inclusion criteria and after obtaining his consent.

The investigator will perform the pleuropulmonary ultrasound following the clinical examination carried out by the physician in charge of the patient.

The patient's care is unaffected by the pleuropulmonary ultrasound's outcome, which is unknown to the physician in charge of the patient.

Data collection after the patient's discharge from the emergency department.
