The FDA is applying a good deal of resources toward a framework for regulation of artificial intelligence (AI) and machine learning (ML), but there are several sources of drag on those efforts. According to the FDA's Jana Delfino, one of these is that there is little agreement between regulators on a number of definitions, including the meaning of terms such as "validation," a problem she said must be solved if the field is to advance in a meaningful manner.

Following the temporary lapse in FDA inspections of manufacturing sites amid the COVID-19 pandemic, this year has already seen more class I medical device recalls issued than in all of 2020.

The COVID-19 pandemic brought in-person inspections of device manufacturing sites to a near halt, but that has left the agency with a significant backlog in these inspections. The FDA’s Associate Commissioner for Regulatory Affairs Judith McMeekin said recently that the FDA is intent on prodding Congress to provide the Office of Regulatory Affairs (ORA) with more monies, particularly given the meager increases in funding for oversight of the med-tech industry in the past few years.
