What a report is

A report is not proof that the device was the cause of the event.

FDA says:

Adverse event reports submitted to FDA do not undergo extensive validation or verification. Therefore, a causal relationship cannot be established between product and reactions listed in a report. While a suspected relationship may exist, it is not medically validated and should not be the sole source of information for clinical decision making or other assumptions about the safety or efficacy of a product. Additionally, it is important to remember that adverse event reports represent a small percentage of total usage numbers of a product. Common products may have a higher number of adverse events due to the higher total number of people using the product.

FDA also says:

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.

MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices.

Reports on file

From February 2004 to November 2020, FDA received 19,422 medical device reports that name the brand Freestyle Flash. A brand name is as the reporter or the manufacturer wrote it, so one product can have more than one spelling.

FDA received no report that names Freestyle Flash in the five years to September 2026. The latest report was received in November 2020.

The number of people who use the product is not in the data. A count is not a rate. A count of reports is not a count of events or of patients, because one event can have more than one report.

What an MDR is

A medical device report: one submission to FDA about one event. It has the brand name, the generic name, the manufacturer, the product code, the event type and coded problems. Manufacturers and user facilities must send reports.

Where the data come from

The counts come from the openFDA Device Adverse Event (MAUDE) bulk files, release of 23 Oct 2026. The files have the reports that FDA received through 30 Sep 2026. Brand names, generic names and manufacturer names are as written on the reports. The names of the product codes come from the device classification of FDA.

A report is in the count when a device in it has this brand name, after the site removes differences of punctuation and capital letters. The site does not publish a report narrative, a lot number, a detail of a patient or the identity of a reporter. The record of FDA is the authority. See how the site counts reports, the data sources and the corrections page.

Questions

Do these reports show that Freestyle Flash was at fault?

No. FDA says:

The submission of an MDR itself does not necessarily demonstrate that the device caused or contributed to the adverse outcome or event.

Confirming whether a device actually caused a specific event can be difficult based solely on information provided in a given report.

What event types do the reports record?

Death (3), injury (660), malfunction (18,747) and other (4). The event type is the classification that the reporter gave: death, injury, malfunction or other. FDA does not verify it.
