Clinical Outcomes Assessment (COA)

Clinical Outcomes Assessment (COA) refers to methods used to measure how patients feel, function, or their health status due to a treatment or condition. It includes tools such as questionnaires, interviews, or observations that capture symptoms, quality of life, and daily functioning. COAs help healthcare providers and researchers understand the impact of diseases and treatments from the patient’s perspective, ensuring that care focuses on what matters most to patients and that new therapies are effective in improving their well-being.
