ER.<br />
a) Transport of those injured<br />
Ambulance use data are available from MOH<C. Based on data for 2003/2004<br />
and 2004/2005 we estimate 35,397 ground, 450 air, and 47 water ambulance trips for<br />
2004 based on a proportionate weighting of the data for the two fiscal years. These<br />
aggregate data allow reasonable allocation across injury severity categories with the<br />
following assumptions:<br />
• Each fatality and major injury is transported.<br />
• Ambulance trips involving a combination of methods (a small minority in the<br />
data) are assumed to all involve ground transport and to involve air or water<br />
ambulances as well in proportion to individual air and water ambulance use in the<br />
data.<br />
• Air and water ambulance are allocated according to the proportionate share of<br />
fatalities and major injuries. All remaining fatalities and major injuries transported<br />
by ambulance to hospital are assigned a ground ambulance trip.<br />
• Fatalities not transported to hospital are assumed transported by the Coroner.<br />
• Ground ambulance trips not allocated in the above are assigned to individuals<br />
with minor injuries. This includes those transported a second time to another<br />
facility (day surgery, clinic, or another emergency department).<br />
