Introduction: A review of the medical device adverse events submitted to the United States Food & Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database was undertaken to determine the major sources of the information.
Methods: The reporter’s occupation and source of the medical device report were determined for acquisition dates Jan 1, 1997 to Dec 31, 2018. A total of 7,766,737 adverse event records were analyzed.
Results: 96.6% of reports originated with the manufacturer. Patients (patients/family/friend) were the most frequent submitter of reports directly to the FDA, almost five times as often as physicians. Nurses submitted reports directly to the FDA 2.77 times as often as physicians. Only 0.49% of physician reports were submitted directly to the FDA, representing 0.09% of total MAUDE reports.
Conclusion: Increasing physician reporting directly to the FDA and MAUDE through the MedWatch reporting system is an imperative. Incorporating information from the perspective of the physician has the potential of increasing the quality of the data and improving the reliability of post-market surveillance.

One element in the United States Food & Drug Administration’s (FDA’s) post-market surveillance of devices is the Manufacturer and User Facility Device Experience (MAUDE) database. The database represents reports of adverse events relating to biomedical devices and is used to identify harms that were not common or not observed in premarket testing. Because of the requirement for accuracy, it is imperative to understand who reports events. A previous study observed a preponderance of reports from manufacturers, with few physicians reporting directly to the FDA.1 However, a relatively small subset of data, comprised of two highly litigated companies and one product code, was studied; and the requirement to include the company’s name could result in a potential bias depending on the reporter’s occupation. Because of the importance of these observations, a repeat analysis of the entire MAUDE database was undertaken to determine the reporting source and reporter occupation.
The entire MAUDE database from Jan 1, 1997 to Dec 31, 2018, was downloaded from the FDA’s website2 and uploaded to a PostgreSQL server. Adverse event records, which were contained in the Master Event File, were analyzed for Reporting Source and Reporter Occupation.
A total of 7,766,737 adverse event records were analyzed. The manufacturer submitted 96.62% of the reports. Table 1 shows a breakdown of the top 16 reporter occupation codes which comprise 97.9% of the total records. Only 3.38% of reports to this dataset were independent of the manufacturer; physician reporting directly to the FDA (voluntary reporting) represented a very small proportion (0.09%) of total MAUDE reports.
Table 1 Reporting source and occupation of reporter – Jan 1, 1997 to Dec 31, 2018
A total 17.75% adverse event reports list the reporter’s occupation as a physician. Only 0.49% of these reports were submitted directly to the FDA. The manufacturer submitted 98.97% of physician reports.
In this analysis, “Nurse” was listed as the occupation in 3.16% of total reports. Nurses made reports directly to the FDA over twice (2.77 times) as often as physicians.
The “patient/family/friend” category was listed as the occupation in 12.7% of the total reports; 96.5% of these reports were submitted by the manufacturer. Patients most frequently submitted reports directly to the FDA, almost five times as often as physicians.
Attorney was listed as the occupation in 2.04% of the total reports. The manufacturer submitted 98.6% of attorney reports, possibly prompted by litigation.
Risk managers were the second most frequent submitter of reports directly to the FDA, three times as often than physicians. 24.1% of the total risk manager reports were submitted directly to the FDA.
In 2018, there were 88,090 reports submitted the MAUDE. Physicians made 262 or 30% of 861 reports submitted directly to the FDA (0.30% of total 2018 MAUDE reports).
The presence of a large number of manufacturer reports in the MAUDE is to be expected, since manufacturers and distributors are required to submit a report to the FDA, if their medical device caused or contributed to a severe injury or fatality. However, the exact definition of a severe event is not well defined. These two entities are responsible for 96.62% and 0.46% of the reports submitted to the MAUDE, respectively. Facilities are required to submit adverse event reports for medical devices to both the manufacturer and the FDA.3,4 However, user facility reports accounted for only 1.43% of the total MAUDE reports, which raises questions of the current regulation’s effectiveness.1 Physicians and physician offices are not required by federal law to submit reports to the FDA of events involving biomedical hardware.
Reporting directly to the FDA
Patients (patients/family/friend) were the most frequent submitter of reports directly to the FDA, almost five times as often as physicians. Nurses made reports directly to the FDA 2.77 times as often as physicians. Attorney was listed as the occupation in 2.0% of total reports in the MAUDE but infrequently submitted directly to the FDA—see Table 1. The vast majority of attorney reports were manufacturer reports. In a highly litigated subset studied by Kavanagh, et al.,1 attorney was the most frequent occupation, comprising 42.2% of total MAUDE reports and 99.3% of these were submitted by the manufacturer.
Kavanagh, et al, also observed that MAUDE adverse event reports were unstructured with a paucity of objective data.1 For example: They observed that in records which indicated the elevation of blood cobalt, less than 4% had units for reporting ion concentrations. Our analysis found that the vast majority of physician reports were submitted by the manufacturer where there is no guarantee that significant redaction will not take place. Physicians reporting directly to the FDA through their MedWatch reporting system will bring an important perspective and has the potential of increasing the quality of the data and improving the reliability of post-market surveillance and improving patient safety.
The FDA needs objective, unbiased, complete data relating to any adverse device-related incident. Physicians bring a unique perspective and can provide vital information which is critical to post-market surveillance of approved devices. Unfortunately, physicians rarely submit a report directly to the FDA. This may be due to a relatively unstructured and time-consuming reporting process. Building reporting functions into electronic medical records, including ready access to a device’s Unique Device Identification (UDI) code, could encourage reporting and improve the quality of MAUDE adverse event reports. In addition, educational institutions and professional associations should educate students and physicians on the importance of submitting reports to the FDA and how to access and input data into MedWatch.
The conclusions in this review do not represent the policy of the FDA.
