Each year, the FDA receives several hundred thousand medical device reports of suspected device-associated deaths, serious injuries and malfunctions. Medical Device Reporting (MDR) is one of the postmarket surveillance tools the FDA uses to monitor device performance, detect potential device-related safety issues, and contribute to benefit-risk assessments of these products.
Mandatory reporters (that is, manufacturers, device user facilities, and importers) are required to submit certain types of reports for adverse events and product problems to the FDA about medical devices. In addition, the FDA also encourages health care professionals, patients, caregivers and consumers to submit voluntary reports about serious adverse events that may be associated with a medical device, as well as use errors, product quality issues, and therapeutic failures. These reports, along with data from other sources, can provide critical information that helps improve patient safety.
The Medical Device Reporting (MDR) regulation (21 CFR Part 803) contains mandatory requirements for manufacturers, importers, and device user facilities to report certain device-related adverse events and product problems to the FDA.
Manufacturers: Manufacturers are required to report to the FDA when they learn that any of their devices may have caused or contributed to a death or serious injury. Manufacturers must also report to the FDA when they become aware that their device has malfunctioned and would be likely to cause or contribute to a death or serious injury if the malfunction were to recur.
Importers: Importers are required to report to the FDA and the manufacturer when they learn that one of their devices may have caused or contributed to a death or serious injury. The importer must report only to the manufacturer if their imported devices have malfunctioned and would be likely to cause or contribute to a death or serious injury if the malfunction were to recur.
Device User Facilities: A "device user facility" is a hospital, ambulatory surgical facility, nursing home, outpatient diagnostic facility, or outpatient treatment facility, which is not a physician's office. User facilities must report a suspected medical device-related death to both the FDA and the manufacturer. User facilities must report a medical device-related serious injury to the manufacturer, or to the FDA if the medical device manufacturer is unknown.
A user facility is not required to report a device malfunction, but can voluntarily advise the FDA of such product problems using the voluntary MedWatch Form FDA 3500 under the FDA's Safety Information and Adverse Event Reporting Program. Healthcare professionals within a user facility should familiarize themselves with their institution's procedures for reporting adverse events to the FDA. See "Medical Device Reporting for User Facilities", a guidance document issued by the FDA.

The Voluntary Malfunction Summary Reporting (VMSR) program was established in 2018 and permits manufacturers to report certain device malfunction medical device reports (MDRs) in summary form on a quarterly basis. It reflects a pilot program conducted in response to changes made by Section 227 of the Food and Drug Administration Amendments Act of 2007 and the goals for streamlining malfunction reporting outlined in the commitment letter agreed to by the FDA and industry and submitted to Congress, as referenced in the Medical Device User Fee Amendments of 2017 (MDUFA IV) Commitment Letter. The FDA believes the program will enhance the FDA's capacity to effectively monitor many devices.
In the Federal Register of December 26, 2017 (82 FR 60922), the FDA issued a notification outlining the FDA's proposal to grant an alternative under 21 CFR 803.19 to permit reporting by a manufacturer of certain device malfunctions in summary form on a quarterly basis, subject to certain conditions, and requested comments from the public. On August 17, 2018, (83 FR 40973) the FDA issued a notification granting this alternative and describing the overarching principles for the VMSR program. Key among these principles is transparency of this information to the FDA and to the public, regardless of whether the information is reported as an individual Medical Device Report (MDR) or VMSR. Under the VMSR program, manufacturers submit separate summary reports for each unique combination of brand name, device model, and problem code(s). Each summary report identifies the total number of reportable malfunctions and are available to the public in MAUDE. Importantly, mandatory submission of individuals reports of death or serious injury events, continue to be required, under sections 803.50 and 803.52, or 803.53, as applicable.
In addition, products or device malfunctions for a given product are not eligible for the VMSR program when:
- a malfunction involves a substantially similar device that necessitated remedial action to prevent an unreasonable risk of substantial harm to the public health;
- a malfunction involves the same or similar device marketed by the manufacturer of a device that is the subject of a recall reportable under 21 CFR Part 806, until the recall is terminated;
- the FDA has determined that individual malfunction reports are necessary to provide additional information or more rapid reporting for an identified public health issue;
- the FDA has determined that a specific manufacturer is no longer allowed to participate in the program;
- the reportable malfunction is a new type of malfunction that the manufacturer has not previously reported to the FDA for that device.
The FDA encourages healthcare professionals, patients, caregivers and consumers to submit voluntary reports of significant adverse events or product problems with medical products to MedWatch, the FDA's Safety Information and Adverse Event Reporting Program.
Medical device reports are submitted to the FDA by mandatory reporters (manufacturers, importers and device user facilities) and voluntary reporters (health care professionals, patients, caregivers and consumers).

Voluntary MedWatch Reporting for Patients, Health Professionals and Consumers (Form FDA 3500):
Patients, healthcare professionals and consumers who find a problem related to a medical device are encouraged to report medical device adverse events or product problems to the FDA through MedWatch, the FDA Safety Information and Adverse Event Reporting Program. Submit reports to the FDA through the MedWatch program in one of the following ways:
- Complete the MedWatch Online Reporting Form
- Download form or call 1-800-332-1088 to request a reporting form, then complete and return to the address on the pre-addressed form, or submit by fax to 1-800-FDA-0178.
To Report an Emergency
If you have identified a public health emergency, you may use the following contact information to alert the FDA:
FDA Office of Crisis Management, Emergency Operations Center

The Manufacturer and User Facility Device Experience (MAUDE) database contains mandatory reports filed by manufacturers and importers from August 1996 to present, all mandatory user facility reports from 1991 to present, and voluntary reports filed after June 1993. The MAUDE database houses MDRs submitted to the FDA by mandatory reporters (manufacturers, importers and device user facilities) and voluntary reporters such as health care professionals, patients and consumers.
Although MDRs are a valuable source of information, this passive surveillance system has limitations, including the submission of incomplete, inaccurate, untimely, unverified, or biased data. 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. Because of this, MDRs comprise only one of the FDA's several important postmarket surveillance data sources.
June 21, 2019: In the spirit of promoting public transparency, the FDA is making Alternative Summary Reporting (ASR) data available to the public on the MDR Data Files page. These data files include ASRs submitted to the FDA between 1999 and April 2019.
In 2017, the FDA began to sunset the ASR Program and requiring manufacturers with ASR exemptions to submit, in addition to the spreadsheet, a companion report that includes the total number of events being summarized. The companion reports are available in the public MAUDE database and represent a subset of the events in the ASR spreadsheets posted on the MDR Data Files Page.
Individuals are also able to request information related to Medical Device Reports by submitting a Freedom of Information Act (FOIA) request either in writing or online.
