Based on patient home address, travel time and travel distance to the nearest community hospital and PCI-capable hospital will be obtained through calls to commercial Web page (MapQuest or Via Michelin). ZIP code will replace patient home address when unavailable. Previous studies have shown that this method provides reasonable estimates. To account for peak travel time, slowdowns of 20% will be factored in during the hours of 7 to 9 AM and 4 to 7 PM, Monday through Friday.
