1,740 reports arrived in the 12 months to August 2026, down 16% from 2,082 in the 12 months before.

The event types recorded are malfunction (99.3%) and injury (0.7%); across all pump, infusion, insulin, to be used with invasive glucose sensor reports (product code OYC) death is recorded in 0.3% and malfunction in 85.5%.

The patient problems coded most often are hyperglycemia, hypoglycemia and elevated ketones/ diabetic ketoacidosis. 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."
