Post-Market Surveillance (PMS)
Post-Market Surveillance (PMS) is the systematic monitoring of a medical device's safety and performance after it has been cleared for sale. Manufacturers track adverse events and real-world data to identify defects and meet regulatory reporting obligations.
What is Post-Market Surveillance (PMS)?
Post-Market Surveillance (PMS) is the ongoing process by which a medical device manufacturer monitors how its product performs once it is in real-world clinical use, after regulators have allowed it to be sold. Rather than relying only on the controlled data gathered before clearance, manufacturers collect signals from actual patients, providers, and facilities to confirm the device behaves as expected.
This monitoring includes tracking complaints, adverse-event reports, malfunctions, and field corrections, then analyzing that information for patterns that might indicate a defect or emerging safety risk. Regulators such as the FDA require manufacturers to report certain events and, in some cases, to run structured post-market studies.
Why does Post-Market Surveillance matter in healthcare?
Pre-market testing can only observe a device under limited conditions and patient numbers, so rare or long-term problems often surface only after wide deployment. Post-Market Surveillance is the mechanism that catches those issues, supporting recalls, label changes, or design improvements before harm becomes widespread.
For facilities that use a high volume of devices and implants, including surgery centers, surveillance feedback loops affect which products stay on the shelf and which carry new handling warnings. Clear surveillance data also helps clinical and supply teams respond quickly when a manufacturer issues a safety notice.
