Safety Data Handling and Reconciliation
Safety data management ensures serious adverse events (SAEs) are captured, reported within regulatory timelines, and consistent across the safety database and the clinical database. Know the definitions: an SAE is any event resulting in death, life-threatening condition, hospitalization/prolongation, persistent disability, congenital anomaly, or requiring intervention to prevent one of these. Know the reporting clock: initial SAE reports generally within 24 hours of the site becoming aware, with follow-up as information arrives.
Reconciliation is the process of comparing the clinical database (eCRF AE/SAE data) against the sponsor's safety database to ensure consistency of terms, dates, severity, causality, and outcomes. It occurs at predefined intervals and must be complete before database lock. Key players: site, monitor, safety/PV team, and data management.
Traps: assuming reconciliation is a one-time event at lock (it is periodic); confusing seriousness (regulatory criterion) with severity (intensity, e.g., mild/moderate/severe); failing to reconcile causality and outcome fields, not just the term; and treating an SAE identified after the reporting window as non-reportable (late reporting still requires documentation and reporting). Another trap: assuming the data manager reports SAEs to regulators - the PV/safety group does.
Rule of thumb: reconcile on term, dates, seriousness, severity, causality, and outcome - a match on term alone is insufficient. Worked example: the eCRF lists an SAE as "moderate" while the safety database lists "severe." Reconciliation flags the discrepancy; the site clarifies; both databases are updated and the resolution is documented before lock.
