You see exactly where it missed and why. A Burna AI pilot runs for 90 days in one department, against success metrics agreed before it starts, and every grade carries the CTCAE criterion and the line in the medical record that produced it, so a missed metric traces back to the cases behind it. Blind grading shows how your own raters agree on the same cases, which separates a question about the record from a question about the grade. A pilot measures the workflow at your site; agreement between the engine and expert clinicians is measured separately, in a concordance study Burna AI is running as a Mayo Clinic Platform_Accelerate participant, covering 1,600 cases from a de-identified dataset of 3 million patients across three campuses, against an adjudicated two-clinician reference panel, with readout in December 2026. Pilots are low commitment by design.
