Both events involve hospitalization. One is not an SAE. The other requires an initial report within 24 hours.

A third participant, enrolled in a study that excludes pregnant women, calls Monday morning with a positive home pregnancy test. There is no adverse event -- no symptom, no complaint, no clinical abnormality. But the coordinator reaches for a different form entirely, because pregnancy reporting follows its own pathway with its own timelines, its own forms, and its own follow-up obligations that may extend months beyond the pregnancy itself.

The previous lessons in this module taught you the mechanics of SAE reporting: when the clock starts, what the initial report must contain, and how to manage follow-up updates through resolution. Those mechanics apply universally. But the clinical scenarios that trigger SAE reporting vary enormously, and the nuances of each scenario -- the specific documentation requirements, the investigator judgments, the follow-up obligations -- differ in ways that matter for regulatory compliance and participant safety.

This lesson takes you through the scenarios that generate the most questions and the most errors: hospitalization in all its permutations, death regardless of cause, pregnancy and its outcomes, and the protocol-defined events that require SAE-like reporting even when standard seriousness criteria are not met.
