Pedestrian traffic injury in Victoria, Australia.

Introduction: Road traffic injuries are the fifth leading cause of years of life lost, with pedestrians comprising 39% of all road deaths (Global Burden of Disease Mortality and Causes of Death Collaborators [1]). Programs that use injury surveillance data to identify high-risk targets for intervention are known to be effective for reducing injury. This study aims to identify trends in the population incidence of pedestrian traffic injury (PTI) in Victoria, Australia.

Method: A retrospective review of data from the Victorian Emergency Minimum Dataset, the Victorian Admitted Episodes Dataset, the Victorian State Trauma Registry and the National Coronial Information System was conducted of patients with a PTI who present to a public hospital emergency department, were admitted to hospital, sustained major trauma or who died of their injuries from January 1st 2009 to December 31st 2013. The primary outcome measure was population incidence of pedestrian traffic-related emergency presentations, hospital admissions, major trauma and deaths.

Results: Over the study period, 1838 cases presented to a public hospital emergency department and were discharged without admission to hospital and an additional 3241 cases were admitted to hospital. Of these, 628 cases were classified as major trauma including 90 in-hospital deaths. From January 1st 2008 to December 31st 2011, a total of 216 deaths occurred. A decrease in the population incidence of emergency presentations for PTI was observed over the study period. No significant change was observed in the population incidence of hospital admissions, major trauma cases or deaths from PTI. The demographics of PTI were observed more commonly to be young, intoxicated males and pedestrians aged over 65 years.

Conclusions: Although the population-adjusted incidence of emergency presentations for PTI in Victoria has decreased from 2009 to 2013, no change was observed in the incidence of hospital admissions, major trauma or pedestrian fatalities. Novel programs designed to address high-risk groups should be considered to achieve further reductions in PTI and severity of injuries.
