The clock started just now. Not when the investigator is notified. Not on Monday morning when the coordinator returns. Not when the hospital sends discharge records. Now. The moment the coordinator heard the word "admitted," the site became aware of information that reasonably suggests a serious adverse event has occurred -- hospitalization meets SAE seriousness criteria -- and the reporting timeline began.

This distinction between awareness and everything that comes after it is, in my experience, one of the most consequential concepts in safety reporting. I have reviewed audit findings where the root cause of a late SAE report was not negligence or incompetence but a genuine misunderstanding about when the clock starts. The coordinator believed that she needed to confirm the hospitalization, or speak to the treating physician, or wait for the investigator to review the case before the event "counted" as an SAE. And in every instance, the auditor's conclusion was the same: the clock started at awareness. Everything else was already inside the timeline.

You already know the seriousness criteria from Module 3. You can identify when an adverse event meets the threshold for an SAE. This lesson is about something different: the precise moment that recognition occurs, the scenarios in which it occurs, and the immediate actions you must take when it does.
