There is a growing emphasis on including patients' perspectives on outcomes as a measure of quality care. This recent interest has spawned the rapid development and testing of patient-reported outcome measures (PROMs), through which patients report on their perception of the outcomes of the care they received. Their use has moved significantly from medical research toward applications in the clinical setting, quality measurement, and system accountability. While the use of as measures of clinical or treatment effectiveness, especially in chronic conditions, is widespread, their use in the emergency department (ED) setting is currently limited. In ED care, PROMs could offer promise since 80% of patients are discharged without any other way to track outcome. We explore the development and use of PROMs in publications on benchmarks and patient-centered care.
