Updated FDA Medical Device Reports (MAUDE) available in the data library

The NICAR Database Library has just updated the U.S. Food and Drug Administration’s Manufacturer and User Facility Device Experience Database(MAUDE).

Current with reports received by the FDA through June 28, 2013, the data include nearly 3 million records of problems involving medical devices. These problems include injuries, deaths and product malfunctions. 

The dataset has a unique MDR report number for each incident and contact detail for the manufacturers and distributors. The age and expiration date for devices are also available in some instances. A memo field includes narratives that describe how problems occurred. 

The reports are pulled from two forms: Medwatch 3500 and 3500A. Health officials use form 3500 to voluntarily report adverse events. User facilities (hospitals, clinics, etc.) as well as product distributors and manufacturers are required to report problems; they use Medwatch 3500A.

MAUDE files come in CSV format and SQL format (for MySQL users only). If you'd like something different, contact us and we'll do our best to help you out. Email or call (573) 884-7711.

The reports in this database detail problems with medical devices, both malfunctions and in some cases human error. Journalists can research reports on a particular brand device to identify, for example, if it is prone to cause complications. Keep in mind that some of these reports are voluntary, and that some devices are used much more heavily than others.  

Also note that the data do not include patient-specific information (which has been removed for privacy reasons) or geographic information.
