Clinical Outcomes Assessment (COA)

clinical outcome assessment (COA) is a measure that describes or reflects how a patient feels, functions, or survives. Types of COAs include:

  • Patient-reported outcome (PRO) measures
  • Observer-reported outcome (OBsRO) measures
  • Clinician-reported outcome (ClinRO) measures
  • Performance outcome (PerfO) measures

These assessments are essential for understanding the impact of medical treatments on patients’ lives and wellbeing. They help healthcare providers and researchers make informed decisions about patient care and new therapies.
