People who participate exclusively in the ACGME match would not be in that number, they would be non-participants. In addition, of those 19 that did not match, most are probably also participating in the ACGME match. The overall match stats for DO programs tends to be in the area of 85-90%, but unfortunately no real compiled stats for both exist.
To use super vague numbers, lets look at overalls:
41% of DOs matched AOA/Military in 2013. Its assumed that pretty much everyone else (59%) applied through to the ACGME match. The ACGME match rate for PGY-1 osteopathic applicants was 75.4% in 2013. That means that of the remaining 59%, 44.5% matched and the remaining 14.5% failed to match. Now that makes a total of 85.5% of DOs matched AOA/Military or ACGME programs.
Unfortunately, there is no real way to know how many of that remaining 14.5% got GME via the AOA scramble, and how many were successfully SOAPed. That said, it seems safe to say that the majority of DOs (mid-high 90-something%) end up at some GME. With the new COCA regulations in June 2013, all DO schools will have to demonstrate that >98% of their graduates were successfully placed in GME across 3 years, so at very least, LMU-DCOM will have to have >98% of their graduates placed in GMEs.
