Introduction

A Clinical Outcome Assessment (COA) is any assessment that may be influenced by choices of human, judgement or motivation which may either directly or indirectly support the evidence of treatment benefit. COAs depend on the implementation, interpretation and reporting from a patient, clinician, or an observer. FDA (2015)

Types of Clinical Outcome Assessments 

1. Patient-Reported Outcomes (PRO)
2. Clinician-Reported Outcomes (ClinRo)
3. Observer-Reported Outcomes (ObsRo)
4. Performance-Outcome (PerfO)

• Patient-Reported Outcomes (PRO): This is any report of the status of a patient's condition that comes directly from the patient about the status of his/her own condition without ammendement or interpretain of the patient's report by a clinician or anyone else.It can also assess the patient perspective on functioning activities that may also be observable by others. An example of this is pain severity or feeling of nausea
• Clinician-Reported Outcomes (ClinRo): This COA reflects the evaluation of a patient's condition by a healthcare professional, it is based on the report that comes from a trained health care professional after observation of a patient's condition. a good example of this is the pain rating scale
• Observer-Reported Outcomes (ObsRo): This is a measurement based on an observation by someone other than the patient or a health professional. This is usually done by patient's non-clinical care giver, family or anyone living around such patient and observes the patient in daily life. A good example is the assessment of a patient's cognition.
• Performance Outcome (PerfO): A PerfO is a measurement based on a task performed by a patient according to instructions that is given to the patient by a health care professional. An example of this is measure of gait speed.[2]
