I am thinking about switching to EM this year if possible.
Essentially impossible. We are well beyond the match and new interns are starting in 2 weeks. Unless someone doesn't show for their program, you don't have any options to start this year. As far as I know, all EM programs in the US have filled.
How do i go about this?. Should i contact programs directly? How will my current program react or help me since i do not want to do this behind their back.
Your reply will be greatly appreciated
Some programs are supportive and some get pissed off. It will strongly depend on the program and your relationship to it and the PD. Your program director will have to write you a letter of recommendation and release you from current program in order to go to another program.
Keep in mind, that you will probably need to come in as an intern, though you may get some credit for months that overlap between EM and IM in the intern year.
The best way is for an intern to drop out and you slide into their spot. That requires watching the websites that list open positions and being ready to dive on any available spot. You have to be willing to move at a moments notice and go pretty much anywhere. Things will have to be primed if you want to do this, so you will have to have things squared away with your program.
I don't know the Match rules well enough to know if you could get an extra match position. However, I don't think you would be eligible.
That basically leaves going through the match again. You have used up two years of your funding, so you will either need to be an excellent candidate, so that a program is willing to give up money to take you or find a hospital system that is over cap and less concerned about how much funding you bring with you. You will need to get a bunch of letters of recommendation, including one from your PD, and they will need to be good. A letter from a known Emergency Physician that you have worked with would also help. Your personal statement will need to address why you a much better fit for EM than you are for IM.
