All good points by AmoryBlaine on why EM may not be the right field for anyone who wants "to do trauma." Me, I like trauma but I'm perfectly happy about the role I have with trauma. But I still wanted to put in my two cents about the importance of trauma training in residency. I agree it's not that complex but I'm a believer that good trauma experience in residency is invaluable. It's the time to get comfortable with trauma airways, chest tubes, lines, throwing in that stitch in an active bleeder, etc. And depending on where you want to practice, there are plenty of trauma patients that have active medical issues and it's nice to have experiences in residency where traumatic and medical issues coincide.
I also agree that most EP's will not see the amount of trauma they see in residency. While bad trauma can be extremely infrequent in a small non-academic hospital, it can happen and it can happen when there is no surgeon in-house overnight. I would still argue for the benefit of a wide variety of trauma experience in residency even if the practice of EM in the community doesn't involve a whole lot of trauma.
I guess it all depends on where you see yourself ending up after residency. And just because surgery team is called doesn't mean that EM just sits back. Again, while infrequent, bad trauma can occur in the suburban non-academic center where there may be no in-house surgeon.
Again, agree that most traumas aren't really that exciting which is why I advocate for programs with good trauma experience because it will only give you more experience with the bad traumas as well as the atypical/benign presentations of trauma that turn out to be something.
