An outcome measure based on a report that comes directly from the patient (e.g., study subject) about the status of the patient’s health condition without amendment or interpretation of the patient’s response by a clinician or anyone else. A PRO can be measured by self-report or by interview provided that the interviewer records only the patient’s responses.
