AI falls short diagnosing COVID-19 in real-world trial

A U.S. group conducted a prospective observational study across 12 hospitals to evaluate the real-time performance of an AI model to detect COVID-19 on patient chest x-rays. While the model appeared promising when tested on a publicly available dataset, it was inadequate for diagnosing patients who presented with COVID-19 symptoms, the researchers found.

“It may be impossible to develop a model solely based on [chest x-ray] findings alone to differentiate between participants with COVID-19 and non-COVID-19 diagnoses,” wrote senior co-authors Erich Kummerfeld, PhD, and Dr. Christopher…
