Enhanced FoCUS in Patients With Shortness of Breath

It was a retrospective observational study performed in a internal medicine ward of a French University Hospital. Patients were identified in the hospital database, pertinent features and eFoCUS findings were extracted and anonymized. Inclusion criteria: * Adult patients admitted to an internal medicine ward from the ED for acute shortness of breath. * Realization of an eFoCUS prescribed by the physician in charge of the patient Exclusion criteria: • Comprehensive echocardiography already performed Methods For each identified patient, pertinent data (demography, initial diagnosis and treatment (diuretics, antibiotics, anticoagulants)) and eFoCUS findings were extracted from the hospital files, anonymized and entered in a LibreOffice spreadsheet. Extracted diagnosis were gathered into the following categories: Community-acquired pneumonia (CAP), Acute cardiogenic pulmonary edema (ACPE), Pulmonary embolism (PE), Chronic Obstructive Pulmonary Disease (COPD) and other (OTHER). Objectives and endpoints * The main objective was the therapeutic change induced by eFoCUS. The primary endpoint was defined by the pooled introduction or discontinuation of diuretics, antibiotics or anticoagulants associated with eFoCUS results. * The secondary objectives were diagnosis modifications induced by eFoCUS. Data analysis * Numerical data were presented as mean ± SD or as median with interquartile range depending on the normality. The paired Student's t-test was used to compare normally distributed data. The chi-square test was used for the comparison of noncontinuous variables expressed as proportions. A p-value \<0.05 was considered significant. All p-values were two-sided. Statistical analysis was realized with R (4.03.3) in the Rstudio® environment.
