Retrospective error detection methods, such as trigger tools, are widely used to uncover the incidence and characteristics of adverse events (AE) in hospitalized children. This review sought AEs identified by three trigger tools: Global Trigger Tool (GTT), the Trigger Tool (TT) or the Harvard Medical Practice Study (HMPS) method. Results from the trigger tools were widely variable, similar to an earlier review in adult acute care, and suggest the need for strengthening reporting standards.

Emergency department clinicians were interrupted an average of five times per hour but did not perceive these interruptions negatively.
