There will still be bias, and it will likely remain for at least another decade. The good news is that many formerly AOA programs will continue to favor DO applicants for a while as well. So while it will get harder for DOs to match, we won't be locked out of any fields.
A few quick points. Idk what UNECOM's clinical courses require, but not all DO schools take the DO shelf exams. At my school we take all NBME (MD) shelf exams other than family medicine (have to fit OMM in somewhere...). We do all have to take COMLEX, which sucks, but that's life.
Mandatory lecture attendance doesn't just occur at DO schools, I've talked to MD students who had significant mandatory lecture attendance as well. It does seem like DO students on this site complain about it more, maybe that's why it comes across as a DO problem, but I assure you it's not unique to osteopathic schools.
I generally agree that MD schools typically have better clinical rotations, but there are cases where DO schools are superior. Especially if the attending at the MD school doesn't actually do any teaching and you just follow them around on rounds and have to figure everything out yourself. I don't know how common this is, but I had a friend who is now a resident that went so far as to tell me he wish he had gone to a different school because his IM rotation was so bad (later changed his mind, as it was his first rotation, but I haven't forgotten that conversation as I was applying to the school at the time). I'd also add that surgery rotations at MD programs with many surgical residents can be notoriously bad. I've got friends who literally stood behind a wall of residents and other medical students for their whole surgery rotation and got no experience at all with actual surgery. For my rotations I did all the same pre-rounding and rounding as MD students would and got to scrub in for 7-8 cases as first or second assist/week. Two of the students on my rotation going into surgery got to perform a minor surgeries under supervision of the attending, something I haven't heard any MD students having the opportunity to do until 4th year sub-i's. The ironic thing is that surgery is typically a field that favors MDs, and some of them may have far inferior clinical experiences to their DO counterparts.
Again, agree with most of what you're saying, but at the same time I've heard plenty of attendings make complaints (less so on here) when they have no idea what they're talking about with DO school rotations. Some of the misconceptions I've heard about DO education in general from MDs have blown my mind (the craziest being an MD thinking all our clinical attendings were either DOs or chiropracters, which led to an interesting conversation where he realized he knew nothing at all about the DO profession). Some DO schools do have shadowing, one of my rotations was essentially shadowing, not because the attending wouldn't let us do anything but because the hospital didn't allow any non-employee access to their EMR or to see patients without physician oversight. So given that 3 students were on rotation, he felt it was better to have us observe and just teach while seeing the patient/right after than have us do everything as he and 2 other students watch you, then have him step in and correct everything you say/do wrong in front of the patient.
Most DOs in those surgical sub-specialties went through AOA programs, not ACGME programs and there is extremely heavy bias. So much so that there are only 1 or 2 DOs who match into ortho or neurosurg or derm or any other very competitive field on the ACGME side each year. Plastics is even worse as there's only 2 or 3 DOs who have ever matched into integrated plastics (I know because my school produced the first one in 2012 or 2013). Also, trauma surgery is not it's own field, it's a fellowship pursued after a gen surgery residency, so it is pretty reasonable (although harder) for a DO to enter than a surgical field with it's own residency like ortho or neuro.
To give a pre-med example: getting into an ACGME ortho or neurosurg program as a DO is like getting accepted into an MD school with a 22 MCAT (495 on the new scale). It's possible and a few people get in with that score every year, but it's very uncommon and wouldn't recommend a person with that MCAT apply without either some serious app re-building or being exceptional in every category with some sort of connection where they're applying.
@hales1120 , if you get into the MD school, I'd go there. Not because UNECOM isn't a good school or there's anything wrong with it (I'm not too familiar with it, but from what I understand it is a solid school), but because you won't have to worry about the handicap of coming from a DO school attending the MD program. I also don't think the reasons you're giving for preferring the DO school aren't really strong enough to override an MD acceptance to that school (similar curriculum, both near home in a smaller state, similar tuition [actually cheaper at tufts if you get the 25k scholarship], etc). If it were me, I'd take the MD acceptance (and I'm saying this as a 4th year DO student with no regrets about my school choice).
