FDA's MAUDE database holds 1,756 reports that name the brand "Fresenius 2008k" (kdi), received between October 2009 and May 2016; the manufacturer given most often on reports is Fresenius Medical Care North America. Spellings of one product vary from report to report.
0 reports arrived in the 12 months to August 2026, and none 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 event types recorded are death (76.8%), injury (22.9%) and malfunction (0.3%); across all dialyzer, high permeability with or without sealed dialysate system reports (product code KDI) death is recorded in 5.9% and malfunction in 64.6%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are insufficient device problem information (97.6%), device operates differently than expected (0.2%) and mechanical problem (0.2%). The patient problems coded most often are death, myocardial infarction and cardiac arrest. 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."
