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.Please note that the MAUDE web search feature is limited to adverse event reports within the past 10 years.Please see the MDR Data Files webpage for Device Experience Network (DEN) and Alternative Summary Report (ASR) data received by the FDA. Because of this, MDRs comprise only one of the FDA's several important postmarket surveillance data sources. In addition, the incidence or prevalence of an event cannot be determined from this reporting system alone due to under-reporting of events, inaccuracies in reports, lack of verification that the device caused the reported event, and lack of information about frequency of device use. The MAUDE database houses MDRs submitted to the FDA by mandatory reporters 1 (manufacturers, importers and device user facilities) and voluntary reporters such as health care professionals, patients and consumers.Īlthough MDRs are a valuable source of information, this passive surveillance system has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data. The FDA uses MDRs to monitor device performance, detect potential device-related safety issues, and contribute to benefit-risk assessments of these products. Each year, the FDA receives several hundred thousand medical device reports (MDRs) of suspected device-associated deaths, serious injuries and malfunctions.
