Manufacturer and User Facility Device Experience (MAUDE) database represents reports of adverse events involving medical devices.

The searchable database contains the last 10 years of medical device report (MDR) data. MAUDE may not include reports made according to exemptions, variances, or alternative reporting requirements granted under 21 CFR 803.19. The downloadable 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 public may search the database for information on medical devices that may have malfunctioned or caused a death or serious injury. Data for the past 10 years is available through the end of the previous month. The FDA seeks to include all reports received prior to each monthly update. The inclusion of some reports may be delayed by technical or clerical difficulties.

Data more than 10 years old through 1995 is available in zip files as listed below by year.

MAUDE data is not intended to be used either to evaluate rates of adverse events or to compare adverse event occurrence rates across devices. The FDA reviews all medical device reports (MDRs) received. The FDA's analysis of MDRs evaluates the totality of information provided in the initial MDR as well as any MDR supplemental reports subsequently provided. The submission of an MDR itself is not evidence that the device caused or contributed to the adverse outcome or event. For example, in certain MDRs, the text of the report may include the word "death" or a related term. However, the MDR would not, and should not, be classified as death unless the reporter believes the patient's cause of death was or may have been attributed to the device or the device was or may have been a factor in the death.

In addition, although MDRs are a valuable source of information, this passive surveillance system has limitations. The incidence, prevalence, or cause 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. Because of these limitations, MDRs comprise only one of the FDA's several important postmarket surveillance data sources.

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 in zip files is updated on a monthly 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 an event. In other words, if a User Facility, Distributor, Manufacturer, and voluntary submitter all report an event, there will be four event records.

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
• Section B

All other data elements will be blank.
