Although the number of events is small, the characteristics of the adverse events identified using the gold standard are similar to the characteristics of the subset identified by the screening method.
The gold standard was a two-stage chart review.
System errors were due to poorly designed systems such as inadequate training, poorly designed protocols, or inadequate or defective equipment.
