This study focused on pediatric patient safety in the emergency department (ED). The first phase involved surveys of pediatric ED staff to assess perceptions of safety. The manuscript for this phase was published in Pediatrics (2009). The second phase of the study involved transmitting incident reports to the data center and classifying and quantifying ED events using a consensus process. Analysis of over 3000 incidents reports was completed and various manuscripts discussing medication errors/events, radiology events, laboratory events, process variance events, and near-miss errors have been published. A newsletter summarizing findings from the medication error review has been distributed to share information on prevention of medication errors in the emergency departments that care for children.
