Trauma registries are an essential means of measuring the extent of injury through the collation and effective use of detailed data on injured patients. They also inform injury prevention strategies, monitor changing patterns of injury and associated management, and facilitate comparison of management across institutions.1,2 Trauma registries also provide an important source of data for determining the financial costs of injury.3,4 The data routinely collected by trauma registries on all aspects of injured patients, from before hospitalisation to patient outcome at hospital discharge, provide the opportunity for improving the management of injured patients and help in the planning of trauma services.1,2,3 The capacity to audit and improve injury management is a fundamental component of any trauma system, and it is arguably the main impetus for continued funding of the current Australasian trauma registries.
