Shielded from scrutiny, Epic algorithms deliver inaccurate information


Several artificial intelligence algorithms developed by Epic Systems, the nation’s largest electronic health record vendor, are delivering inaccurate or irrelevant information to hospitals about the care of seriously ill patients, contrasting sharply with the company’s published claims, a STAT investigation found.

Employees of several major health systems said they were particularly concerned about Epic’s algorithm for predicting sepsis, a life-threatening complication of infection. The algorithm, they said, routinely fails to identify the condition in advance, and triggers frequent false alarms. Some hospitals reported a benefit for patients after fine-tuning the model, but that process took at least a year.
