Patterns of injury from major trauma in Victoria.

Abstract

Basic demographic and injury data were collected on all major trauma patients (ISS > 15) presenting to 25 Victorian hospitals over a 1 year period (March 1992-February 1993). A total of 1076 patients were identified with an Injury Severity Score (ISS) > 15. Of these, 957 resulted from blunt trauma, 68 from penetrating trauma and 51 from burns. Most serious blunt injury was transport-related (n = 652) but falls made up a significant proportion (n = 206). The pattern of injury in blunt trauma demonstrated in this study showed a preponderance of serious head, thoracic and limb injuries with less frequent occurrences of abdominal, spine and facial injuries. In major penetrating trauma, serious injuries of the thorax and abdomen were more frequent. Head injury is the most common cause of morbidity in major trauma patients. Motor vehicle accidents caused the majority of head injuries but, proportionately, head injury was more common in pedal cycle, pedestrian, motorcycle injuries and falls. The low frequency of major abdominal trauma has important implications for surgical training and resource allocation. In Victoria, various injury prevention interventions have been introduced such as compulsory wearing of bicycle helmets, a safer home environment and behavioral modifications through advertising. Injury prevention strategies must continue to target the populations at risk and assess the impact of interventions by accurate injury surveillance. This study was undertaken with the data obtained from Ballarat Base Hospital - S. Walker.
