Missed injuries contribute to increased morbidity in trauma patients. A retrospective chart review was conducted of pediatric trauma patients from 2010 to 2013 with a documented missed injury. A significant percentage of missed injuries were identified (3.01% during July 2012 to December 2013 vs 0.39% during January 2010 to July 2012) with the addition of acute care trained pediatric nurse practitioners to the trauma service at a pediatric trauma center. The increase is thought to be due to improvement in charting, consistent personnel performing tertiary examinations, and improved radiology reads of outside films.
