The medical community calls them signals. A patient falls dead, and they think it might be due to a prescription drug. That could be in the U.K., South America, the United States, or somewhere else. The medical community calls that a signal. They start counting them, and when they get enough of them, they call it noise. When they get enough noise, somebody actually starts to look into it.
If the signals--the information the drug company got when it was reported to them that it was potentially a cause--were immediately sent to the regulators, the regulators could start to open their own files and start to investigate the drug themselves. You could have patients doing their own adverse reaction reports too. So they would get information earlier, and they could act sooner, instead of it taking months and months and months, while the body count rises.
