Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are device dislodged or dislocated (36.4%), insufficient device problem information (13.8%) and naturally worn (3.1%). The patient problems coded most often are joint dislocation, pain and appropriate clinical signs, symptoms and conditions term/code not available. 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."
