In 2017, FDA issued only 44 Warning Letters to medical device establishments. Of those, 11 were related to pre-market issues, which include investigational device exemption violations or lack of approval or clearance. Only 33 of the device Warning Letters in 2017 were issued for cGMP, Quality System, or MDR violations, a remarkable figure since FDA regularly sent over 100 device regulation compliance Warning Letters every year from 2011 to 2015.
One might expect that fewer Warning Letters means fewer inspections, but FDA’s inspection database shows that the number of device compliance inspections has remained fairly consistent from 2011 through 2017. The number of inspections has certainly decreased from a high of 1,859 in 2011, but FDA conducted 1,624 device compliance inspections in 2014, 1,533 in 2015, 1,539 in 2016, and 1,551 in 2017. Clearly, the sudden drop off in Warning Letters has been much steeper than the modest decrease in inspections.
What could be driving this decrease in Warning Letters? I briefly explore three possibilities below. Continue Reading Drop in Warning Letters for Medical Devices Raises Interesting Questions About the Industry
