674 reports arrived in the 12 months to August 2026, down 75% from 2,703 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases.

The device problems coded most often are degraded (98.8%), contamination (2.7%) and corroded (0.8%). The patient problems coded most often are headache, dizziness and dyspnea. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
