Rural-urban variation in injury-related hospitalisation, health outcomes and treatment cost in New South Wales

ObjectiveTo compare differences in injury characteristics, health outcomes and treatment costs between urban and rural residents who were hospitalised following an injury. DesignA retrospective examination of injury-linked hospitalisation and mortality data in New South Wales from 1 January 2010 to 30 June 2014. ParticipantsUrban (496 325) and rural (213 139) residents who were hospitalised following an injury. Main outcome measuresDemographic and injury characteristics, injury severity, hospital length of stay, 28-day hospital readmission, 90-day mortality and treatment cost. ResultsRural residents had an increased likelihood of being hospitalised for injuries from motorcycles, vehicles, animate causes, venomous animals or plants and assault compared to urban residents. Rural residents were less likely to be readmitted to hospital within 28 days and had a lower length of stay and age-adjusted length of stay than urban residents. Injury-related hospitalisations for urban and rural residents cost $4.4 billion and $1.7 billion, respectively. Annually, acute injury treatment ($1.1 billion), rehabilitation ($130 million) and subacute non-acute patient care ($57 million) cost $1.3 billion ($990 million for urban and $384 million for rural residents) in New South Wales. Fall-related injuries and transport incidents were the costliest injury mechanisms for both urban and rural residents. ConclusionsInjuries contribute substantially to hospitalised morbidity and its cost. The development and implementation of injury prevention strategies targeting the most common injuries for urban and rural residents will go some way towards reducing hospitalised injury and its cost.
