Diagnostic Performance of Echocardiography Performed by Emergency Physicians After a Basic Training
Diagnostic Performance of Echocardiography Performed by Emergency Physicians After a Basic Training
After a basic training to echocardiography, emergency physicians will have to answer simple
 clinical questions about circulatory failure mechanisms. The objective of the study is to
 assess the agreement between these answers and those of the expert physician in patients
 admitted in the emergency department with a circulatory failure due to sepsis or not.
 Emergency physicians will volunteer to take part in a basic training on echocardiography. The
 training will include 4 hours of theory, 2 hours of interactive clinical cases and 6 hours of
 tutored practice at patients' bedside (10 to 15 examinations). The objective of the practice
 sessions will be to learn the technical grounds of transthoracic echocardiography (TTE), the
 different views and to identify the anatomical structures. The second part of the study will
 start after the training. Each eligible patient will be successively assessed by two
 investigators: one emergency physician recently trained and the expert physician. The
 echocardiography will be performed as soon as possible in the emergency department before or
 after the initiation of treatment without delaying it. The order of hemodynamic assessments
 will be random depending on the availability of the investigators; both assessments will
 however be performed within 30 minutes. Each investigator will independently read the
 echocardiography in real time at patients' bedside. They will then answer a limited list of
 standardized questions using two-choice answers or predefined choices. Finally investigators
 will choose a therapeutic proposition among a predefined list based on the answers. Only the
 results of the echocardiography performed by the expert physician will be used in patient
 management.
