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 (i.e., 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 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 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 FDA.
Please visit Mandatory Reporting Requirements: Manufacturers, Importers and Device User Facilities for specifics on requirements and associated processes.
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 or through the MedWatcher mobile app.
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 FDA through MedWatch, the FDA Safety Information and Adverse Event Reporting Program. Submit reports to FDA through the MedWatch program in one of the following ways:
- Using the MedWatcher mobile app that allows individuals to submit voluntary reports of serious medical device problems to the FDA using a smart phone or tablet.
Download the MedWatcher Mobile App
- 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
- Voice (24hr/day) phone: 866-300-4374 or 301-796-8240
- FAX: 301-847-8543
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 potential 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 potential under-reporting of events 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.
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.
