Why Quality Audits Don’t Prevent Product Recalls

“Our audit went well, so why are we facing a recall?”

A clean audit report is often mistaken for a guarantee of product quality. But, passing an audit simply means that no major non-conformances were identified at a single point in time. It doesn’t guarantee long-term product safety.

The Philips Respironics CPAP recall is a classic example. For years, the company maintained a record of passing routine regulatory inspections and ISO audits. On paper, their quality management system (QMS) met regulatory requirements.

However, in 2021, Philips issued a massive Class I recall affecting 15 million CPAP, BiPAP, and mechanical ventilator devices globally. The foam inside the machines was degrading, causing users to inhale black foam particles and toxic chemical off-gassing. Regulatory findings later highlighted that indications of foam degradation had existed internally for years without being effectively addressed during routine QMS audits.

Here’s how this applies to your organization:

1️⃣ Auditors rely on sampling due to time and resource constraints. Because they inspect only a fraction of records, latent design flaws or subtle complaint trends can easily remain in uninspected areas.

2️⃣ Scrambling to polish documentation specifically for an audit creates a temporary illusion of compliance. It addresses the appearance of quality rather than underlying operational or engineering risks.

3️⃣ Compliant documentation is necessary but not sufficient. A paper-driven process encourages a tick-the-box approach, whereas a strong quality culture focuses on transparent risk management, objective data analysis, and post-market surveillance.

Quality management isn’t easy, even Fortune 500 companies struggle with it! Sometimes when we see a company struggle, it’s because they think that successful audits = successful quality.
