To clear up the ACLS and ATLS confusion:
You will become BLS and ACLS certified while at DCOM. There are talks of doing PALS too. There is an ATLS course taught by our head of surgery, but you are NOT certified in it since you must have your degree (DO/MD) to be certified.
Also, as a 3rd year, I can tell you we are very prepared for rotations. I don't know anything about top 5% or anything like that, but based on my experience and my colleagues, we can hold our own very well. You WILL know how to perform lumbar punctures, central lines, intubate, etc PRIOR to rotations. The clinical training is very strong at DCOM for sure. You will be able to read an EKG extremely well too....and x-rays. The sim lab is an awesome experience and I can't wait to see it fully develop into the awesomeness it can and will be. Learning how to think like a doc is much different than book learning and the sim lab does a great job at prepping you for that.
