The Washington PostAn influential panel that advises the federal government on science policy proposed Friday that the Food and Drug Administration scrap the process it uses to clear many medical devices for use because the current method can’t ensure they are safe and effective.
The FDA should require more extensive testing of thousands of “moderate-risk devices” — from wheelchairs to artificial hips — that come to market with little study because manufacturers can argue that the devices are “substantially equivalent” to products already in use, the panel said.
A committee of 12 experts convened by the Institute of Medicine said the process allows a device to slowly evolve from its “substantially equivalent” ancestor without ever getting its own assessment for safety and effectiveness. Furthermore, many older devices that are basis for the comparison themselves were never fully tested.
“The public thinks that if the FDA clears and ‘approves’ a device that safety and effectiveness has been considered. But that is not always the case,” said David R. Challoner, a physician who headed the panel.
