missed 2/3
of sepsis cases, in external validation
What the research found
External validation of the Epic Sepsis Model — deployed at hundreds of US hospitals — found it missed roughly two-thirds of sepsis cases, with a real-world AUC of 0.63 versus the vendor's claimed 0.76–0.83, while generating alerts on 18% of patients.
Why it matters for providers
An independent check on a marketed clinical-AI tool found performance far below the vendor's claims — the 'cleared/marketed ≠ proven' gap, in one landmark case.
