Here is what I emailed to another student with same the same question as yours:
If you want MD program and you want to do that right after your 4th
year (without doing an internship, like I did, then know that you
will not be able to do this in Michigan. Michigan requires an AOA
internship).
However, if you are interested in a ACGME program (I will just call
it MD program from now on) then it really does not make that much of
a
difference if you have rotated at the specific program or not. I got
into my program without doing a rotation here or even any rotations
in the illinois area. What most MD programs look for are your
letters of rec (most want SLOR
http://www.cordem.org/slor.htm ), your
deans letter, your board scores, and your class rank.
If you are interested in Calif (I am from San Diego (UCSD)myself so
know what you mean about the snow), then I highly suggest taking and
doing really well on the USMLE... (this was the main reason I did not
get many interviews in Calif...I have only taken COMLEX and did
pretty well on it but most of the programs in calif wanted USMLE
scores. This was not the case with many of the other programs that I
interviewed at, outside of Calif.
One other thing about MD programs is that if you do rotate at their
program and you do really well you might get a "courtesy" interview
that you would not have gotten if they did not know you.. However,
doing 600 ED rotations is definitely a negative thing on your
application ... at the most do 3 ED rotations and even with these see
if you can do a different rotation than just regular ED after you
have completed your first required ED(i.e. EMS rotation, ED research
rotation, ED Sub-Internship, Peds ED etc...)Make sure you do really
really well and get as many SLORs as you can when you do your core ED
rotation.
During your rotations be nice to the residents... most programs
(almost all programs) will have their current residents interview and
choose the new residents..
If you want to do a DO residency (I do not know much about the
process) but I can tell you that when I was a student it seems as if
they placed alot of emphasis on people that had rotated in their
facility and almost exclusively interviewed only the ones that they
knew... (this is definitely different on the MD side)...
As far as Michigan I spent my whole third year there.. mostly at
POH.... Unless things have changed alot since then, and they might
have, I would not do many rotations there.. The patient volume is
way too low and they have way too many residents for the number of
patients ... you will have a easy rotation but not too educational...
Small hospitals are good in that they have a much easier schedule and
you will get more attention from the attending but you will not be
able to do as many procedures (as not many get done in these
hospitals)... you will generally learn more if there is a strong
residency program in the rotation that you are doing as residents
will be your primary teachers....
Well I am being paged now....so I have to go.. sorry for all the
typos (I had to type this email really really fast)....
