By applying machine learning to medical record data, scientists found that secondary bacterial pneumonia that does not resolve was a key driver of death in patients with COVID-19. It may even exceed death rates from the viral infection itself. The scientists also found evidence that COVID-19 does not cause a “cytokine storm,” so often believed to cause death.
This Viewpoint examines the reasons that machine learning has not met initial expectations in health care and proposes that the approach to using machine learni
