The device problems coded most often are entrapment of device (15.6%), off-label use (14.7%) and detachment of device or device component (5.3%). The patient problems coded most often are pericardial effusion, low blood pressure/ hypotension and arrhythmia. 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."
