Two sites have come to my attention that indicate real time divert data.

The first is a site that covers an eight-county region in South Central Pennsylvania.  The status of (17) hospitals is hosted at this site. You can visit the website at http://hospitals.ehsf.org/. The site is based on a package by Med Media, who has a number of EMS solutions. As I'm writing this one of the region's three trauma centers is on divert (Lancaster General), and Gettysburg Hospital has overcrowding in Critical Care, General Medicine and General Surgery.  Oh, and Memorial Hospital is on ED divert as well. And while I was adding links to this post, Good Sam also went on divert.  That's a total of one quarter of this regions hospitals on divert. Wait, there's another one!  Ephrata Community Hospital has joined the ranks of the diverted. 

This link is to Credit Valley Hospital, a 365 bed hospital with 20,000 admissions annualy, in Mississauga, Ontario (a Toronto suburb).   At the middle of their home page at the bottom, there's a stylized picture of an ambulance. Below that it says, "Click here to view our ER admit status."  Here's what the link says this evening:

At the present time we have 23 patients in the emergency department requiring admission to hospital. Because all of our inpatient beds are full, these patients will remain on stretchers in the emergency department until a bed can be found on a nursing unit.

The only way we can make room for these patients is to be diligent in discharging those patients on nursing units whose condition has improved to the point that their doctor feels they can safely recover at home.

We appreciate your cooperation and understanding.

They're apparently boarding 23 patients in the ED awaiting admission to the hospital.  I'm not sure what to make of the second paragraph.

I will continue to search for similar web sites.  If you come across any, please let me know.  In all, these two indicators of capacity are pretty cool.  As the father of a seven year old, I would love to have similar feedback on potential emergency room overcrowding in the Portland area.
