E-collection 'Patient-Reported Outcome Measures (PROMs)'

A patient-reported outcome (PRO) is a health outcome directly reported by the patient who experienced it. It stands in contrast to an outcome reported by someone else, such as a physician-reported outcome, a nurse-reported outcome, and so on. PRO methods, such as questionnaires, are used in clinical trials or other clinical settings, to help better understand a treatment's efficacy. The use of digitized PROs, or electronic patient-reported outcomes (ePROs), is on the rise in today's health research industry and a frequent focus of JMIR papers.
