Introduction: The purpose of this project was to evaluate a tablet-based documentation application for massive transfusion protocols (MTPs). Methods: 13 trauma nurses at a level-one pediatric trauma center were randomly assigned to use paper documentation (n=5) or the tablet-based application (n=8) during simulated MTPs. Documentation completeness was compared using an independent t-test. Tablet users completed a system usability survey (SUS). Results: Documentation of blood product volumes and times significantly improved with the tablet (p=<0.001 and p=0.001 respectively). The tablet received a mean SUS score of 89%. Discussion: A tablet-based application has potential to improve real-time documentation of MTPs.
