I'm a 4th year at SLU going into EM and the new PD for the program is my advisor. I think I should be able to help with a lot of this. I've also interviewed all over the place and have quite a few places for comparison. To start, they definitely don't test your line placement techniques or do any other weird interview day stuff, by the way. That's just a ridiculous rumor.
Let me answer your concerns to the best of my abilities, RustedFox.
Possibilities that I'm considering for these "bad things that I'm hearing":
1. Faculty with bad/uninterested/malignant attitude; especially true if you get the sense that they "can't be bothered with residents".
This is not a problem at all. Nearly all of the faculty have been very helpful and interested in my learning through two different rotations I've completed at the SLU ED (clinical and administrative). There are one or two people who I have had personality clashes with (inherent to life), but all in all, the reason I'm going into emergency medicine is because of the enthusiasm these people had in teaching me. I imagine since they've been good to me, they'll be good to the residents, especially since they've been gung-ho on getting the program off the ground.
2. Poor facility/poor support staff.
To be honest, the facility is not great and fairly dated. It is comparable to the Maricopa ED on a smaller scale, if you have interviewed there. It definitely has a county feel to it, considering the patient population (inner city/poor) and the acuity (high trauma and admission rate, many complicated patients who waited too long to come to the ED). If you're looking for glass doors and plasmas in every room, this is not the place to come. However, you will never find yourself at a lack for resources or supplies. You have access to anything and everything you need.
As for the support staff, it is hit or miss. I've worked with some incredible people who made all of our lives easier and I've worked with some bitter, cynical people, too. Mostly, though, everyone worked hard and did their job. You won't be doing your own labs or peripheral IVs, for example. If you order a test, all of the nurses and techs will get it done in speedy manner. I would say the support staff is about what you'd expect at most places. Solid, but nothing over-the-top spectacular.
3. Poor location/poor salary/poor housing options.
The location is all a matter of personal opinion. It is a medium-sized midwestern city. If you want Chicago or NY, St. Louis might not be for you. However, if you could live in cities like Milwaukee, Kansas City, Indianapolis, Cleveland, or Cinci, St. Louis is comparable. You have plenty of sports (NFL, NHL, MLB, NCAA Div I) and nightlife locations (Laclede's Landing, Soulard, Wash Ave.) if that's important to you. All ethnic foods are represented (one of my favorite places is a Vietnamese place not far from the hospital). I'm married, so I can't comment on the singles scene, but my single friends have never complained. One unique aspect of St. Louis is Forest Park. It is in the dead center of the city and was the site of the 1904 World's Fair. It's bigger than NY's Central Park and almost everything in it free. This includes the Zoo, Art museums, the History museum, running paths, bike paths, an ice-skating rink, and all kinds of sport fields. Even the outdoor theatre there has free nosebleed seats. Forest Park alone makes it a great city for residents with kids. You don't have to break the bank to keep them busy. Overall, most city people should be happy unless you need NY, Chicago, the ocean, or mountains.
Housing is cheap and readily available. Many people buy, even medical students. I live 5 minutes from the hospital in an Italian area called "the Hill" with great restaurants everywhere (very safe area). There's plenty of lofts and condos downtown, also about 5 minutes away (very safe downtown). If you want a suburban feel or a house, you can literally live 15 minutes or less away in a quiet neighborhood with good schools. The only places to avoid are right around the hospital in the "midtown" area (not so safe) or in north city (why St. Louis makes the "most dangerous city" rankings).
As for the salary, I really can't comment. I don't have the info with me and I'm working in the ICU right now (slow day). I remember that it seemed fairly comparable to most other places I interviewed. It wasn't the highest, but it wasn't the lowest, either
Overall, though, the program has the potential to make the right people happy, but, like any program, its not for everyone. The faculty are dedicated and enjoy teaching. The patient population ensures you will get the solid training you need. I guarantee, however, that there is nothing malignant or terrible about it.
I'll try and post some more of the positives and negatives when I have a bit more time later.
