Health status or symptom data reported directly by the patient, not measured by a clinician.
Patient-reported outcomes (PROs) are any outcome reported directly by the patient about their own health, symptoms, function, or quality of life, without interpretation by a clinician or researcher. They are typically captured via standardised questionnaires (e.g. pain VAS, disability indices, quality-of-life scales) and are increasingly used as primary or co-primary endpoints in trials. Their subjectivity and susceptibility to response bias mean they are usually interpreted alongside objective or clinician-rated measures.
