Lived in Atlanta for 3 years working in units, then got into UTC at Chattanooga with Erlanger. I would suggest not working at Grady's units. Everyone knows in the region that you get stabilized in the ER and then transfer to another hospital. Have had multiple friends that worked there and even agency pay wasn't enough compensation for the physical conditions of the facility and to top it off, the attitude is malignant at best. I'm very serious about this, 5 friends saying the same thing is no joke.
From my experience, I still say SI over trauma but that is up to you. It is an open market for you, you certainly have the choice to make. Go look at the units and see the type of patients they have that day and the amount of monitoring involved. Over half of our current class is from SI, none from trauma. Same with the upcoming class and only one from trauma. The SI in Chattanooga, both Erlanger and Memorial, is known for being a farm for potential anesthesia students.
You may also want to look at WellStar Kennestone Hospital. http://www.wellstar.org
A level II hospital, teaching hospital only in the open heart portion, actually the busiest ER in the state 2 years ago, beating Grady, AMC, and even Memorial in Savannah for number of patients seen. Excellent hospital, just opened an open heart program in affiliation with Emory. Multiple units in addition to open heart.
Let us know how it goes.
