Clinical Outcome Assessment

A Clinical Outcome Assessment (COA) is a way to measure how a patient’s health condition affects their daily life, symptoms, or overall well-being. It involves collecting information directly from patients through questionnaires, interviews, or reports about their symptoms, functioning, or quality of life. COAs help healthcare providers and researchers understand the impact of a disease or treatment from the patient's perspective, guiding better clinical decisions and ensuring that treatments improve what matters most to patients.
