PRO

Information about a patient’s health that comes directly from the patient. Examples of PROs include a patient’s description of their symptoms, their satisfaction with care, and how a disease or treatment affects their physical, mental, emotional, spiritual, and social well-being. In clinical trials, PROs may provide information about the side effects of the new treatment being studied. The use of patient-reported outcomes may help plan the best treatment and improve quality of care. Also called patient-reported outcome.
