ED Maps is designed as a tool to access information about emergency rooms. It may not, in all cases, reflect the most up-to-date information. Also, depending upon the internet browser used, not all data on the ED Maps website may be visible. Please note that the location of the ED symbol on the map may not necessarily reflect the exact location of the ED entrance. If you are experiencing a medical emergency, please dial 911 immediately.
Although the site works with multiple internet browsers (e.g., Internet Explorer, Chrome, Safari), we recommend Mozilla Firefox for optimal viewing.
Sometimes, after a lot of map activity, it is necessary to clear a browser cache. To do that, you can use these keyboard combinations (CRTL+SHIFT+R) in Firefox, and (CRTL+F5) IE. More info here
Three map layers are available:
Emergency Departments: Non-specialty, hospital-affiliated EDs as listed in the 2009 NEDI-USA database (as of May 2012).
Visits per hour: Check to see the average number of ED visits seen per hour, which was calculated by dividing annual ED visitvolume by the total number of hours of operation in one year (24 hrs/day x 365 days/yr = 8,760 hrs/yr). EDs were categorized by visit volume into 4 groups: <1.0, 1.0-1.9, 2.0-2.9, and ≥3.0 visits per hour.
EM residency: Check to show EDs that were the primary or only site of an emergency medicine residency program in 2009.
COTH / Teaching Hospital: Check to show EDs in a Council of Teaching Hospital in 2009.
Critical Access Hospital: Check to show EDs in a Critical Access Hospital in 2009.
Federal Hospitals: Check to show EDs in a VA, military, or Indian Health Service hospital in 2009. These hospitals may not be readily accessible to the general public and, for that reason, they are denoted with a special symbol .
