March 31, 2020 - MEDTECH DIVE - BRIEF

  • An analysis of 230 Class III products approved from 2005 to 2015 found 62% of devices that received some form of expedited review were recalled, compared to 30% of those with standard review. Despite having special status, priority review took longer than the standard process, on average.
