Koren 2002 12-hour PUQE: three caller-assigned integers 1-5 (nausea duration, vomiting episodes, and retching episodes over the last 12 hours as in that paper's table). Sum 3-15. magent does not interview the patient. Koren 2002 published no 3-6 / 7-12 / ≥13 total-score cuts; later 24-hour and trimester-long forms are not scored. Not an antiemetic order and not a medical device.
