Inclusion of patient-reported outcome instruments in US FDA medical device marketing authorizations

BACKGROUND: The U.S. Food and Drug Administration encourages the incorporation of the patient voice throughout the medical device total product lifecycle. This study examined the incorporation of patient-reported outcome (PRO) instruments in the evaluation of medical devices over a six-year period. PRO instruments used to inform study endpoints were extracted from the summary documents and clinical trial data of premarket authorizations posted on publicly available FDA databases between October 1, 2014—September 30, 2020. RESULTS: PROs were included in 53% of authorizations, with 34% using PROs as primary and secondary endpoints. This study found that PRO instruments were used in each type of marketing authorization and in all medical specialties examined in this study. CONCLUSIONS: Expanding the current collaborative efforts to develop and modify PRO instruments may help to improve use of PROs in medical device evaluations.
