High adopters of AI-enabled screening tool are more likely to diagnose left ventricular dysfunction than low adopters, Mayo Clinic study finds

A Mayo Clinic study found that clinicians who were high adopters of an AI-enabled clinical decision support tool were twice as likely to diagnose low left ventricular ejection fraction as those who were low adopters. The tool's accuracy was critical in detecting serious health conditions before symptoms appeared.
