“…Of the re-allocating ambulances, 23 out of 27 were at existing sites, 4 were allocated to new sites, the average distance increased for 3 sites (by 319m) and decreased for 20 sites (by 630m (Snyder et al, 2007;Stiell et al, 1999). Specifically, several studies have noted the improved survival of patients with a high risk of mortality when the response time was less than 4 to 5 minutes (Blackwell and Kaufman, 2002;Pons et al, 2005) and have sought to improve the response times through enhancing EMS management and relocating ambulance stations (Gossage et al, 2008;Peleg and Pliskin, 2004).…”
