To ensure the scientific and recognized evaluation of patient-centered clinical research outcomes, the drug development tool qualification certification website of the Center for Drug Evaluation and Research and the Center for Biologics Evaluation and Research have disclosed the information of clinical outcome assessment (COA) submitted for certification, and encouraged the use of certified COA. This paper searched all COA and approval decisions on the website, analyzed the submitted information and certification status of COA, and interpreted the certification technology and process of COA, so as to provide references and suggestions for the development of patient-centered clinical research outcome evaluation.
