The FDAs Center for Devices and Radiological Health (CDRH) is currently taking steps to improve the post-market surveillance, researchers note, including strengthening the condition of approval studies; improving medical device reporting; focusing on risk-based inspections; implementing third-party inspections; communicating risk/benefit information; and refining the FDAs communications strategy.
Distinction from Drug Regulation
In contrast to pharmaceuticals, medical devices are evaluated using a risk-based classification system that determines its regulatory pathway. Devices are placed into one of three classes: Class I devices, representing low-risk items such as examination gloves do not require performance standards; medium and high-risk devices (Classes II and III) such as infusion pumps and defibrillators follow specific regulatory requirements that vary substantially.
By using a risk-based system, said researchers, the FDA recognizes that some degree of risk is inherent in the development of devices, and further, that all hazards cannot be eliminated. There is often little or no prior experience on which to base judgments about safety and effectiveness; devices undergo performance improvement modifications during clinical trials; and results depend on the skill of the user.
