From what I understand, setting it up yourself means calling a doctor up and asking him if he would be willing to take you for rotations for a said period of time. Third years need to rotate through a number of areas including Family practice, rural family practice, Internal med., OB/GYN, Pshychiatry, pediatrics, surgery, and on and on. For each of these areas, you need a docor since it is very unlikey a doctor would be practicing as a pediatrician and a psychiatrist. To add upon the problem, docs sometimes will only take you for a month, which means you have to switch off to another doctor. For example in family practice you have 3 months. That means you need to sometimes hang with three docs. That's some of the stuff you have to deal with trying to set it all up on your own. BUT, If you stay in AZ and within some adjoining states, AZCOM can do it for you and set up all the arrangements. OHHH! Realize too that since CCOM is our sister school, we get to jump in on their rotation sites and they ours. (I'm pretty sure. I'll have to check.) SO that means there may be rotation site available in Illinois as well.
Realize also, that you don't necessarily have to do it one on one with a doctor. You can get your clinical exposure at training hospitals throughout the United Sates. So for example, If I want to do a family practice rotation at Stanford hospital then I need to apply through their application process they have there. Then, I need to pay the fee lots of these hospitals require for rotating through. On top of it all, some of these hospitals will only let you rotate through within a given field for only 1 month. SOOO, that means if you have two more months of the field to go, you need to go and find docs, or hospitals who will take you for the remaining two months.
It's important you pick good hospitals and good docs who will actually teach you stuff. AZCOM has a test waiting for you after each field is done. SO yes, there's a family practice test, and Internal medicine test, surgery test, etc.
It seems really difficult, but the truth is, schools can't cater to every student by provide rotaions within every state and city. This goes for MD schools as well. If you want to rotate in Alaska for example, then good luck, you are on your own. SO in this respect, you can go anywhere you want in whatever city you want just as long as the rotation you set up was approved by AZCOM.
What you can begin to do is ask third and fourth year students about their rotations. Ask them if there's any doc who would be willing to take you and whether or not they are good teachers. You may also want to check out the web sites of various hospitals. They usually have a section on medical education. Under that section you can usually find info on whether or not the hospital will let you rotate through.
That's seriously all I really know at this point. If you need more info. try posting up on the residency/rotation forum.
