A Check-list Including Lung Ultrasound for ED Patients With ARF

Centre Hospitalier Metropole Savoie105 enrolled

Overview

The aim of the study is to evaluate if a check-list including lung ultrasonography can help to identify the etiology of the acute respiratory failure of patients managed at the emergency room. Adult patients admitted to the emergency room for acute respiratory failure will be offered the study. The emergency physician will perform a systematic examination using a checklist, including pulmonary embolism prediction scores, structured clinical examination and lung ultrasound, in order to establish a diagnostic hypothesis. A diagnostic hypothesis will be made after completion of the checklist. The emergency physician can perform additional examinations and treatment after completion of the checklist. The final diagnosis will be checked by an adjudication committee which will have all the documents established during the emergency room consultation and any hospitalization following this hospitalization. The main outcome will be the concordance rate between the diagnosis after the check-list and the final diagnosis.

Conditions

Acute Respiratory Failure

Interventions

The investigator will follow the checklist which includes the collection of anamnestic data and clinical signs, the performance of a pulmonary embolism clinical probability score and a cardiopulmonary ultrasound with count -standardized rendering. After completing this checklist, the investigator will note their diagnosis (list of proposals on the data collection sheet), the treatments started (closed list of therapeutic classes). If he orders other tests, he will write them down and then note the diagnosis made and the treatments prescribed after obtaining the results of these tests. The therapeutic management of patients compared to the usual care in the respective departments may be modified depending on the results of the cardiopulmonary ultrasound . The emergency physician may initiate therapy before the results of additional examinations that he would have usually performed without cardiopulmonary ultrasound.

Outcomes

Primary Outcomes

Agreement between the etiology retained after using the checklist and the diagnosis retained by an adjudication committee after analysis of the entire patient file.

The adjudication committee will meet all 35 inclusions to determine the diagnosis of each patient after analysis of the complete anonymized file which will be provided by locol investigator one month after inclusion.

Time frame: 1 month after inclusion

Secondary Outcomes

Analysis of the diagnosis retained after the checklist in patients with a final diagnosis of COVID-19; analysis of the final diagnosis in patients with a diagnosis of COVID-19 evoked after the checklist

The adjudication committee will meet periodically after analysis of the complete anonymized file to check the COVID diagnosis.

Time frame: One month after inclusion

Collection of treatments started only after completion of the checklist and verification of its suitability for the diagnosis selected

All the treatments started only after completion of the checklist wil be collected prospectively and their appropriateness will be checked.

Time frame: at one day

Collection of additional examinations possibly performed in the emergency unit after the completion of the checklist

All additional examinations performed after the completion of the checklist will be collected

Time frame: at one day

Comparison of treatments introduced after completion of the checklist and after the other additional examinations performed at the emergency room

all treatments delivered after the completion of the checklist and after complementary exams will be collected and classified into therapeutic families (antibiotics, diuretics).

Time frame: at one day

Delay between completion of the checklist and obtaining the results of any other examinations

Time between the completion of the checklist and obtaining the last result of the other examinations performed at the emergency room (except for bacterial culture)

Time frame: At one day
