title: Incidence of paediatric fatal and non-fatal low speed vehicle run over events in Queensland, Australia: eleven year analysis.
abstract: BACKGROUND
  The purpose of this study was to estimate the incidence of fatal and non-fatal Low Speed Vehicle Run Over (LSVRO) events among children aged 0-15 years in Queensland, Australia, at a population level.
  
  
  METHODS
  Fatal and non-fatal LSVRO events that occurred in children resident in Queensland over eleven calendar years (1999-2009) were identified using ICD codes, text description, word searches and medical notes clarification, obtained from five health related data bases across the continuum of care (pre-hospital to fatality). Data were manually linked. Population data provided by the Australian Bureau of Statistics were used to calculate crude incidence rates for fatal and non-fatal LSVRO events.
  
  
  RESULTS
  There were 1611 LSVROs between 1999-2009 (IR=16.87/100,000/annum). Incidence of non-fatal events (IR=16.60/100,000/annum) was 61.5 times higher than fatal events (IR=0.27/100,000/annum). LSVRO events were more common in boys (IR=20.97/100,000/annum) than girls (IR=12.55/100,000/annum), and among younger children aged 0-4 years (IR=21.45/100000/annum; 39% or all events) than older children (5-9 years: IR=16.47/100,000/annum; 10-15 years IR=13.59/100,000/annum). A total of 896 (56.8%) children were admitted to hospital for 24 hours of more following an LSVRO event (IR=9.38/100,000/annum). Total LSVROs increased from 1999 (IR=14.79/100,000) to 2009 (IR=18.56/100,000), but not significantly. Over the 11 year period, there was a slight (non -significant) increase in fatalities (IR=0.37-0.42/100,000/annum); a significant decrease in admissions (IR=12.39-5.36/100,000/annum), and significant increase in non-admissions (IR=2.02-12.77/100,000/annum). Trends over time differed by age, gender and severity.
  
  
  CONCLUSIONS
  This is the most comprehensive, population-based epidemiological study on fatal and non-fatal LSVRO events to date. Results from this study indicate that LSVROs incur a substantial burden. Further research is required on the characteristics and risk factors associated with these events, in order to adequately inform injury prevention. Strategies are urgently required in order to prevent these events, especially among young children aged 0-4 years.
