Tuesday morning, three messages

It is 8:14 a.m. on a Tuesday. The coordinator has not yet opened the electronic data capture system. The coffee is still hot. And already, three messages are waiting.

The first is a voicemail from a participant in a Phase II cardiovascular trial. "Hi, this is subject 1042. I have had a headache since Saturday. It is not terrible, but it will not go away. Just wanted to let you know." The headache started four days ago. The participant is just now reporting it.

The second is a voicemail from a family member. "My husband is in the study. He was admitted to the emergency room last night. They are keeping him for observation. Can someone please call us back?" The coordinator does not yet know what happened, but the word "admitted" changes the urgency of the entire morning.

The third is not a voicemail at all. It is a flag in the electronic diary system: a participant has missed three consecutive daily entries, and the entries before the gap include a notation that simply reads "dizzy."

Three messages. Three different reporting pathways. Three adverse events -- at minimum -- waiting to be identified, triaged, and documented. None of them occurred during a study visit. None of them were elicited using the open-ended questioning techniques from the first lesson in this module. And every one of them starts a clock the moment the coordinator becomes aware.

This is the reality of between-visit AE identification. The systematic techniques you learned in Lesson 1 -- the elicitation funnel, the body system review, the directed inquiry -- apply at scheduled visits when the participant is sitting in front of you. But adverse events do not confine themselves to your visit schedule. They happen on Saturdays, on holidays, at 2 a.m. And they reach you through phone calls, diary entries, spontaneous reports from participants or their families, notifications from outside physicians, and occasionally from sources you did not anticipate at all.

Your obligation does not change based on the channel. Per ICH E6(R3), Annex 1, Section 2.7, adverse events must be identified and reported regardless of how they come to the site's attention. The method of identification varies. The standard of documentation does not.
