Exactly what the side panel showed on Fri Nov 13, 2026 04:55 PM for patient P33 (visit KE-P33, note KN-P33-1), and every response to it. Synthetic demonstration data.

What was shown

Heart pumping fraction (type) · shown as Needs a look (stated, not supported by the record)

The note says “Heart failure with reduced ejection fraction”; the latest ejection fraction is 48% on 2026-10-13, which does not fit the type written (needs 40% or lower). An earlier value was 30% on 2025-05-21.

Evidence

  • Ejection fraction 48% · echocardiogram 2026-10-13 (transthoracic, biplane): Left ventricular ejection fraction 48% by biplane method. · ECHO-P33-2
  • Ejection fraction 30% · echocardiogram 2025-05-21 (transthoracic, biplane): Left ventricular ejection fraction 30% by biplane method. · ECHO-P33-1

Options (fixed order, nothing pre-selected)

  1. Heart failure with reduced ejection fraction (HFrEF) · not met · latest 48% on 2026-10-13
  2. Heart failure with mildly reduced ejection fraction (HFmrEF) · met · latest 48% on 2026-10-13
  3. Heart failure with preserved ejection fraction (HFpEF) · not met · latest 48% on 2026-10-13
  4. Heart failure with improved ejection fraction (HFimpEF) · met · earlier 30% on 2025-05-21, latest 48% on 2026-10-13 (change +18 points)
  5. Other (I will write it)
  6. Clinically unable to determine
  7. Not clinically supported (I will revise the note myself)
