An evaluation of road crash injury severity using diagnosis based injury scaling

In Western Australia, information in Police crash reports currently provides the only measure of injury severity following a road crash. This paper makes use of ICD-Based Injury Severity Score (ICISS) methodology to determine the severity of road crash injuries using linked hospital and death records. The severity of an injury is determined by calculating threat to life ratios for patients admitted to Western Australian hospitals from 1988 to 2006. Certain road user groups appear to be grossly under-reported by Police as requiring hospitalisation, when compared to hospital records. Pre-defined severity of injury thresholds were used to determine the seriousness of an injury using hospital admission records. Analysis indicates that serious injuries contribute to approximately 26 per cent of Western Australian hospital admissions by road crash casualties and are growing at a faster rate than nonserious injuries. This paper reports trends in hospital admissions and injury severity for road crash casualties over the period 1988-2006. The severity of an injury is determined using hospital discharge summary information. Comparisons are made with numbers of road crashes reported to Police and for hospital admissions, making use of linked hospital and death records for the period.
