Spellings of one product vary from report to report.
9 reports arrived in the 12 months to August 2026, up 13% from 8 in the 12 months before.

The device problems coded most often are pumping stopped (27.4%), device displays incorrect message (9.9%) and pumping problem (9.9%). The patient problems coded most often are no patient involvement and air embolism. 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."
