title: Data validity and integrity checking in clinical trials information systems.
abstract: Data validity and integrity checks in clinical trials (CT) databases have special procedures. We describe a new logic-driven system, coupled with a CT information system, which manages data anomalies found in CT databases. Q-GEM identifies data problems, and issues, emails to study sites, and tracks data discrepancy forms until their final resolution.
