“We’ve Never Had a Complaint” — The Most Dangerous Sentence in Medical Devices

At first glance, hearing “We’ve never had a complaint” sounds like excellent news.

No customer dissatisfaction.
No product issues.
No safety concerns.

But for Quality and Regulatory professionals, this statement should trigger an entirely different question:

How do you know?

What Is a Complaint?

Many organizations believe a complaint only exists when a customer submits an official complaint form or explicitly uses the word “complaint.”

Regulators take a much broader view.

A complaint may include:

  • Unexpected device performance
  • Product malfunctions
  • Customer dissatisfaction
  • Usability issues
  • Distributor observations
  • Technical support interactions
  • Returned products
  • Any information suggesting the device may not meet requirements

Complaints Are Often Hidden

Potential complaint signals can be found in:

  • Customer emails
  • Distributor communications
  • Service reports
  • Sales team discussions
  • Training sessions
  • Social media comments
  • Technical support tickets

If these sources are ignored, valuable post-market information is lost.

Why Zero Complaints Can Be a Red Flag

Imagine a company with:

  • 5,000 devices on the market
  • Products sold in 20 countries
  • Daily clinical use

And yet…

  • No complaints
  • No usability observations
  • No customer questions
  • No returned devices

Experienced auditors may not celebrate.

Instead, they may question whether the complaint handling process is effective enough to capture real-world information.

Complaint Handling Impacts the Entire Quality System

Weak complaint collection doesn’t only affect one procedure.

It directly influences:

  • Clinical Evaluation Reports (CER)
  • Post-Market Surveillance (PMS)
  • PMCF activities
  • PSUR preparation
  • Benefit-Risk assessments
  • State-of-the-art reviews

If complaint data is incomplete, clinical evidence may also be incomplete.

Five Practical Recommendations

  1. Define complaints broadly.
  2. Review every customer-facing information source.
  3. Create a structured complaint screening process.
  4. Trend data regularly to identify recurring issues.
  5. Periodically challenge your system by asking:

“Would an auditor agree that we’ve identified every potential complaint?”

Final Thought

The next time someone proudly says,

“We’ve never had a complaint,”

don’t celebrate immediately.

Ask instead,

“How do we know?”

Because in medical devices, the absence of complaints is not always evidence that everything is working perfectly.

Sometimes, it’s evidence that nobody is looking.
