WASHINGTON – The 2019 annual forum hosted by the Medical Device Innovation Consortium (MDIC) takes place as the National Evaluation System for health Technology (NEST) approaches full operability. Acquiring the data needed to employ NEST as a source of real-world evidence (RWE) is still an issue. Harlan Krumholz, a cardiologist and health care researcher at Yale University and Yale-New Haven Hospital, said that disruption of the business models of the "data oligopolies" is critical for use of RWE for devices in both the pre- and postmarket settings.
