ABSTRACT
A patient-reported outcome (PRO) is a direct subjective assessment by patients about aspects of their health, including symptoms, function, emotional well-being, quality of life, utility, and satisfaction with treatment. PROs ask patients to evaluate the impact and functional implications of the disease or treatment to reflect their interpretation of the experience, which is influenced by their internal standards, intrinsic values, and expectations. As such, PROs provide unique information that is unavailable from other sources.1
