Actually, I was going to define it more broadly. It's any reaction that would require some medical intervention. I'll give you an illustrative example of what would be and would not be--say, a poisoning incident--because this is more commonly part of the entire database of adverse events, as well as a risk profile.
A poison control centre may indeed get a phone call from a mother worried that her child had ingested something from underneath the kitchen counter. That gets logged as a poison statistic. There may never have been an ingestion, just simply that there was a suspicion on the mother's behalf, she made the phone call, and so on. But had there been one that required the child to go to the hospital and have an intervention, that would have been logged as an actual event versus a report. So at a very simple level it requires an intervention, and it also really reinforces the need for good clarity on definition.
