Manufacturer and User Facility Device Experience Database - (MAUDE)

MAUDE data represents reports of adverse events involving medical devices. The download data files consist of voluntary reports since June 1993, user facility reports since 1991, distributor reports since 1993, and manufacturer reports since August 1996. The searchable database data contains the last 10 year's data. MAUDE may not include reports made according to exemptions, variances, or alternative reporting requirements granted under 21 CFR 803.19.

An on-line search is available which allows you to search the CDRH's database information on medical devices which may have malfunctioned or caused a death or serious injury. MAUDE data is current through the end of the previous month. FDA seeks to include all reports received prior to the update. However, the inclusion of some reports may be delayed by technical or clerical difficulties.

MAUDE data is not intended to be used either to evaluate rates of adverse events or to compare adverse event occurrence rates across devices.

Please be aware that reports regarding device trade names may have been submitted under different manufacturer names. Searches only retrieve records that contain the search term(s) provided by the requester.

The data is also available in zipped files for downloading. The data is updated on a weekly basis.

These files were then compressed ("zipped") in order to save space. For these files to be useful to you, you'll first have to download them, unzip them, and then import them into a database or word processor for your further processing.

The releasable MAUDE data is presented in four logical records types. For this data to be meaningful, you should download all four types of files. The four record formats contain all releasable information on MEDWATCH Form 3500.

Downloading Hint: When downloading the MAUDE data files to a database such as Microsoft Access, it is recommended that you first open, then save the data file in Microsoft WORD. This will add an "end of record" marker to each MAUDE record that can be recognized by Microsoft ACCESS. For files such as the FOIDEV files, you may need to put in an extra character at the end of the first record prior to importing the file, otherwise the last column of data may be lost.

Master Event Data: A distinct master event data record will be present for each source reporting anevent. In other words, if a User Facility, Distributor, Manufacturer, and voluntary submitter all report an event, there will be four event records. These individual source records are related via the EVENT KEY. EVENT KEY is an internally-generated key which links multiple sources to a single event.

Device Data: Record Type 2 contains information related to the device(s) involved in the event.

Patient Data: Record Type 3 contains information related to the patient(s) involved in the event.

Text Data: Record Type 4 contains textual information from MEDWATCH Form Sections B5, H3, and H10.

All record types are linked via the MDR REPORT KEY.

For distributor reports which have had subsequent manufacturer reports, a special data element, MANUFACTURER LINK FLAG, will be set to 'Y'. In this case, the DISTRIBUTOR information (Section F on the master event data record) will be present; otherwise, these data elements will be blank.

The following files are available: (File Sizes are approximate)

[Accessibility]

Note: This documentation is intended to be used in conjunction with a copy of Medwatch Form 3500A and 3500.

Record/Data Characteristics:

• The data has one record per line, with the data fields in a pipe-delimited, (i.e., "|") format
• All data elements are alpha-numeric
• All text fields contain whatever data was provided/entered. If no information was provided/entered the field will be left empty. If an asterisk ("*") is present, it represents what was entered on the 3500/3500A.
• All "FLAG" data elements have the value of "Y" for Yes, "N" for No, or are blank if no data was available/entered.
• All fields identified as multiply-occurring represent data elements which may have multiple values. Each value will be present in the field, separated by a comma. The word "OTHER" may appear as one of the values if the "Other" box was checked off. If the whole field is blank, no data was reported/entered.
• Section G CONTACT address information may not necessarily be the address where the device is manufactured.

Special Note for REPORT NUMBER data element:

The REPORT NUMBER data element represents Manufacturer Report Number, Distributor Report Number, or internally-generated voluntary report number, depending on the source of the record.

This REPORT NUMBER field will be blank when:

• User Facility submitted the report
• Distributor report has not been followed by a subsequent Manufacturer report.

Special Notes for Voluntary Reports and User Facility Malfunction Reports:

The only data elements which will be present on the Master Event Record will be:

• NEW RECORD
• DEVICE EVENT KEY
• REPORT SOURCE CODE
• MDR REPORT KEY
• EVENT KEY
• Section B

All other data elements will be blank.
