if you care more about trauma than medicine, then you want trauma surgery, not emegency medicine. Honestly dude, stop worrying about something 10 years down the line at this point 🙂
In some hospitals, only the trauma team, run by trauma surgery, treats trauma patients. A trauma/critical care fellowship allows an Emergency Physician one opportunity to go beyond working in the ED. Many hospitals will allow those trained in critical care to manage patients in the ICU. Additionally, as ED boarding times increase, Critical Care trained EPs are starting to create new inroads into ED critical care...ICU level care delivered in the ED by EPs.
Also, does every EM residency require research? Yuck! When do EM residents have time for research?
