A contract resolved against the verifier’s own arithmetic cannot be overturned, so it is excluded from the headline and shown here. Two patients supply 64% of the adjudicated denominator, across 16 patients.

Findings

  1. Local AUROC 0.7564 against card 0.8107. Acceptance FAILS in record GHM-0001.
  2. Alert precision 0.1083 against card 0.2007. Work FAILS.
  3. Card claim M-4 carries no number. No Claim Contract issued.
  4. Confirmed Validity 56.2% per patient (9/16 stays, 95% CI 0.31-0.81). Per patient-hour it would read 90.9%.
  5. Two patients supply 64% of the adjudicated denominator.
  6. 24 resolutions are inconclusive because the reference label and the screening criteria disagree. They arise only on misses; counted against us the per-event figure is 85.1%.
  7. 41 events fell outside the reporting period and are excluded.
  8. 20.0% of audited passes were overturned, implying roughly 306 missed events this period.
  9. 518 verdicts were routed for review and 0 reached the closure state the policy requires within its service level. Landing 0%, so EVC is 0% whatever the verdicts were worth.
  10. Coverage counts outputs the verifier received. An output never sent is invisible to it.
