This systematic review was undertaken to provide clear enumeration of adverse events that have occurred during intrahospital transport of critically ill children, risk factors for those events, and guidance for event prevention to clinicians who may not be fully aware of the risks of transport. The recommendations for reducing adverse events frequently given in the 40 articles that met the inclusion criteria (reflecting 4104 children transported) included: use of checklists and improved double-checks (of, e.g., equipment before transport).
