Clinical Outcome Assessment (COA)

Clinical Outcome Assessment (COA) refers to the process of measuring a patient's health status, symptoms, or quality of life directly from the patient or through observations. It includes tools like questionnaires, interviews, or physical tests that capture how a person feels, functions, or reacts to treatment. COAs help healthcare professionals evaluate the effectiveness of treatments, understand patient experiences, and make informed clinical decisions. They are essential for ensuring that care focuses on what truly matters to patients and that new therapies are evaluated accurately from the patient’s perspective.
