Materiovigilance: From Device Failure to Safety Reform, The Growing Importance of Materiovigilance Systems

Materiovigilance (Mv) plays a vital role in safeguarding patient health, much like pharmacovigilance—yet its focus is on medical devices. It involves the identification, reporting, and monitoring of medical device–associated adverse events (MDAEs) to ensure devices used in healthcare remain safe, reliable, and effective. Through continuous safety surveillance, Mv has enabled the timely recall of defective, malfunctioning, or unsafe devices, thereby preventing serious patient harm. It encourages the reporting of all types of events—whether serious or minor, expected or unexpected, frequent or rare, or even those linked to devices with incomplete specifications. Every report contributes to a deeper understanding of device performance. By gathering real-world safety data, Mv helps enhance device design, functionality, and overall efficiency, minimizing complications and failures. It also raises alarms about counterfeit, substandard, or poor-quality devices, protecting both healthcare workers and patients. Continuous reporting of medical device-associated adverse events (MDAEs), whether critical or minor, known or unknown, frequent or rare, contributes to timely identification of defective or malfunctioning devices. This process has supported several global devices recalls and has strengthened patient protection. Commonly reported issues include device breakage or malfunction, infections at insertion sites, organ injuries, device-related surgeries, and even fatalities. Many global health authorities have established structured MDAE reporting systems with clear timelines—such as MedWatch (USA) and MedSafe (New Zealand).To ensure safer healthcare, both professionals and consumers must understand the importance of Mv, know how to report device-related problems, and be aware of action steps when adverse events occur. Materiovigilance ultimately strengthens trust in medical devices and supports a safer healthcare environment for all.
