Clinical outcome assessment« Back to Glossary Index
A clinical outcome assessment (COA) measures the change in a clinical outcome. For example, a clinical endpoint of a clinical trial studying a new therapy may be reducing the number of hospitalizations for respiratory distress. In this case, the clinical outcome is hospitalizations for respiratory distress. The COA will be the tool used to quantify the number of hospitalizations for respiratory distress for each participant of the study.
