Probably going to be more competitive now since ED is getting more popular. Take the USMLE.
Looking at the ERAS 2016 statistics and the NRMP 2017 match data (for the last cycle)
587 DO candidates applied through ERAS
283 DO candidates matched EM, 3 matched Med-EM combined program, 1 matched Ped-EM combined program for a total of 287 matches
This is a 48.9% match rate. Seems to be a bit different vs. the 77% Charting outcome number would provide. I didn't look at that document, perhaps it counts AOA program too?
Bonus data: 74 DO candidates applied to ACGME ortho. 3 matched for a 4% match rate. 172 IMG plus FMG applied to ACGME ortho, 13 matched ortho for a 7.5% match rate
I for one, am very glad that my chosen field of radiology appears to be more accessible, and dare I say, demonstrate less bias, toward my DO colleagues.
Just in case I messed up the years by misunderstanding how the cycles align (I am used to the fellowship cycle by now), I also looked up the ERAS 2016 NRMP report. 224 DO's matched EM that year and 4 matched ortho.
