What are Clinical Outcome Assessments (COAs)?

The concept of measuring patient quality of life with patient-centered outcomes research emerged in the 1990s along with health-related quality of life questionnaires. These questionnaires are now broadly known as Clinical Outcome Assessments (COAs) and also referred to as instruments, tools, measures, scales or tests.

According to the Food and Drug Administration (FDA), “a clinical outcome assessment is a measure that describes or reflects how a patient feels, functions, or survives”.


The different types of Clinical Outcome Assessments

  • Patient-Reported Outcome (PRO): completed by the patient regarding their own health status.
  • Observer-Reported Outcome (ObsRO): completed by an observer of the patient, normally a parent or caregiver.
  • Clinician-Reported Outcome (ClinRO): completed by a Clinician or other HCP based on their observation of the patient.
  • Performance Outcomes (PerfO): completed by an interviewer based on tasks that the patient is asked to perform.

Over 30 years of experience distributing COAs in the field of Patient-Centered Outcomes
