AI-ENABLED ASSESSMENT OF CARDIAC FUNCTION AND VIDEO QUALITY IN EMERGENCY DEPARTMENT POINT-OF-CARE ECHOCARDIOGRAMS

Published:February 24, 2023DOI:https://doi.org/10.1016/j.jemermed.2023.02.005

      Abstract

      Background

      The adoption of point-of-care ultrasound (POCUS) has greatly improved the ability to rapidly evaluate unstable emergency department (ED) patients at the bedside. One major use of POCUS is to obtain echocardiograms to assess cardiac function.

      Objectives

      We developed EchoNet-POCUS, a novel deep learning system, to aid emergency physicians (EPs) in interpreting POCUS echocardiograms and to reduce operator-to-operator variability.

      Methods

      We collected a new dataset of POCUS echocardiogram videos obtained in the ED by EPs and annotated the cardiac function and quality of each video. Using this dataset, we train EchoNet-POCUS to evaluate both cardiac function and video quality in POCUS echocardiograms.

      Results

      EchoNet-POCUS achieves an area under the receiver operating characteristic curve (AUROC) of 0.92 (0.89–0.94) for predicting whether cardiac function is abnormal and an AUROC of 0.81 (0.78–0.85) for predicting video quality.

      Conclusions

      EchoNet-POCUS can be applied to bedside echocardiogram videos in real time using commodity hardware, as we demonstrate in a prospective pilot study.
