Not a nurse yet, but I've been in EMS in this area for five years so I can say that all the ER's TEND to get busy. The busiest in Louisville is probably University Hospital followed by Norton and Jewish Downtown. It's just they are the 'downtown' hospitals and tend to get the businest. Your rest are all relatively as busy as the rest. You want to stay away from all the Jewish Satellite hospitals as they tend to be the least busy and while Norton Brownsboro CAN get busy, it usually is RELATIVELY quiet.
