Questions received from a recent seminar on Post-Market Surveillance - MDR's

QUES: In "Become aware" - it says "including any trend analysis." This suggests that non-public information is included in all this. Please speak to any difference between public and company-private (secret) information?

ANS:  The FDA has not made a distinction between public and private information in a MDR investigation and response.  And they repeatedly require trending of CAPA / Complaint data in their 483’s (I have also seen this personally) and have sometimes done it themselves (the trending) when such data is missing.  You do have the right to indicate what information you supply that you desire to be treated as “confidential” and/or redacted from FOI responses from them (21 CFR 803.9(b)(1)).  They may or may not agree/comply. 

QUES: Manufacturer Reporting Requirements –

A reportable death, serious injury, or malfunction is based on information a manufacturer receives or otherwise becomes aware of, from any source.

  • Here and throughout subsequently, it appears that this includes company-internal information. Okay. But, what does that mean in practice? Of course, it does not mean everything, such as lunch-cooler conversations. Is there some easy definitions, such as information that is subject to audit? Or, something else?

ANS:  If you become aware of any instance of your device causing a death or serious injury, or could cause such, from any source, you are required to report it – the only qualifier is the following on “reasonably suggests” (which could even apply to your lunch-cooler example, depending…).  21 CFR 803.03 “Become aware means that an employee of the entity required to report has acquired information that reasonably suggests a reportable adverse event has occurred.” You start an investigation, first to determine if it is true, and report the findings up to the time you report initially to the FDA at/within the timeline required, with the information you have at the time.  If incomplete, you then continue your investigation until you have gone as far as you can in good faith efforts, reporting what is verifiable to the FDA as supplements / updates to the original MDR.  

In cases where you determine that the problem is not MDR-reportable, you should still record it as a complaint, and include the investigation data leading to the conclusion not to report, retained in your complaint file (such as your example of serious event lunch-cooler talk found to be incorrect).  

QUES:  The “Manufacturer” - Manufactures components or accessories that are medical devices.

  • Consider product produced inside and outside US either by true manufacturer or under license by another.

Consider illicit versions (copies) produced not by or under license of the true manufacturer.

Produced not in US, used not in US.

  • Is FDA involved?

 ANS:  The FDA is involved in devices produced in the US, no matter where sold, if the conditions of an MDR submission are met. Same for product produced outside the US but marketed and/or used (e.g., IDEs …) in the US.

 Counterfeit devices in complaints that were presented to you as yours by the user, initially as your product (and third party reprocessed SUDs where you are the OEM and not the reprocessor but thought to be the one responsible due to old labeling…) are reportable to the FDA by you, if you're the one who becomes aware of the problem, and if they meet the requirements of MDR submission, with the subsequent findings (and follow-on MDR update / submission to the FDA) that the product is not yours with justification / facts proving so.

QUES: “Become aware” - 1

You said: "You can't blow this stuff off."

  • No question, but this was a key takeaway that prompted my questions.

 “Become aware” – 2

  • You talked about "delay."
  • The following question comes up often for us. Can you answer or provide a resource to answer this question:

Is there a difference between a Delayed Result < 24 hours vs. Delayed Result >= 24 hours?

This question is in the context of a lab instrument giving a result to the doctor: bacterial identification, antimicrobial susceptibility, blood work, etc.

Where the typical answer is on the order of < 24 hours response time.

 ANS:  I don’t remember saying “You can’t blow this stuff off”, but I agree with the thought.

I did not discuss anything on any “delayed result<24 hours vs. delayed result + or > 24 hours”, and am not sure of the question.  If this is a manufacturer-defined malfunction, which is a reportable category for the MDR if that was a requirement for the product and it didn’t meet it - it malfunctioned. Your MDR SOP should define how to handle, but the FDA doesn’t want splitting hairs on timing of problems, etc.  If a problem occurred at a certain time interval, it’s possible / assumed it could occur sooner or later the next time, absent test data to the contrary. However this is a specific product question which I cannot address in this general context further.

The only "delay I would have talked about is a "become aware" delay, i.e., the information may have related to an event that occurred much earlier, but was delayed in getting to you / the company.  You are obligated to send the MDR once you become aware of it, even it it actually occurred considerably earlier - days, weeks, months (I haven't seen a time limit, as long as the version of the device causing the problem is still on the marketplace - there's still a risk posed to the potential users, hence the need for the MDR).   

QUES:  “Caused or contributed” to death / serious injury

  • If someone using the device makes a mistake? This is easily understood as: reportable.
  • What about off-label use? You said: reportable. Okay.
  • What about an actor that is purposely doing it wrong? I understand this to be same as off-label use: reportable.
  • What about a bad actor? That is, someone purposefully using the device to cause harm?

ANS:  All the above are reportable, including the last bullet point.  Your findings of such (such as bad actor / willful misuse) would then be included in your MDR to the FDA.  Most risk and use / human factors requirements include user error as a consideration, but purposeful misuse is not (in use / risk analysis, unless done by a doctor who can use a device in any way they deem necessary to benefit a patient, usually with the patient’s agreement after informed of the benefit / risk – ISO 14971 …), as I mention in other presentations on use / human factors engineering and/or device risk management.  So you would still report a “a bad actor” in your findings and if you have solid proof, you would have no way to prevent that (as you have no way to prevent a doctor from their “off label” use of the same product), which would become part of your findings (cite as part of your rationale the references cited above).  


 QUES:  The most famous case at our company internally: A device analyzing blood running in a hospital lab would beep when it needed attention. There was an instance where the device was beeping at night, which bothered a person somewhat like a janitor, someone not in the lab hierarchy. They knew how to and did  turn off the beeping. When the morning shift came in, the machine was not beeping so they missed doing what they need to with it, and did not report a result to the doctor as they would have if they had known to address it. A death occurred.

  • Was this a mistake? No. Was this an actor-purposely-wrong? Probably. What if this had been a bad actor, purposely causing harm?
  • Perhaps you have other examples (or a book or articles I could read) about this topic? 

ANS:  Sorry, I don’t have a reference for such a book.  However, ICH 62366-1 on Usability Engineering and ISO 14971 on Device Risk Management discuss briefly purposeful misuse.

However, since a death could (and did) occur, the MDR requires that it be reported.  The findings reported to the FDA would be as indicated above.  The organization having that incident and their legal department, et al, and senior management, would have to determine corrective actions to be taken internally regarding controls and behavior of company personnel to prevent such from recurring – e.g., both the janitor who made an unauthorized change to the device, AND the morning shift who should have verified it’s operation first thing.  Your IFU’s may have to address the fact that such events could compromise results.


Be aware that any change to your labeling for your products’ field problems may require a new marketing submission, e.g., 510(k), especially a caution or warning.  See the two guidance documents on Device Changes and the 510(k):
