Hi and welcome to AZCOM,
jhug is correct in what DOCARE does, I'm sure there is a website for them, but offhand I cannot recall the address. I'll get back to you on that.
The mission that AZCOM goes on is usually in February (I think it's because of the locale and the weather being more favorable at that time of year. I was told there was no air conditioning so the summer would have been brutal).
Dr. Burdick prefers that those participating have some working knowledge of Spanish, but it is not a prerequisite written in stone. Another faculty member, Mr. Federico Aguilar, often gets students involved in health fairs that are sponsored by ALMA (an association of Latin American physicians). All med students are welcome and these are usually on Saturday mornings or afternoons. The clients are Spanish speaking and it benefits all tremendously to have students like yourselves (enthusiatic and Spanish speaking) participate.
Interviews never seem to end! To answer jhug's other questions, yes, I feel well prepared to meet the challenges of a residency. With all programs and curricula, there are pluses and minuses to everything. I liked the preceptorship based rotations for the following reasons: I had highly qualified and great role models to follow. I not only learned to manage outpatients but I managed their inpatients as well (that depends on what hospitals your preceptors are affiliated with). I would pre-round on inpatients, write notes, and be prepared to discuss orders with the physician when we rounded on patients together. Then, after notes and H&P's were reviewed, we'd go to the clinic, see the outpatients and then round in the evening to see how the inpatients and new admits were. They were busy but wonderful days (for me, at least).
However, I arranged my rotations this year to be primarily inpatient based, so I could get the feel for what it is going to be like during my residency. The teaching is way different. For preceptor based, you must select those who enjoy teaching and are willing to impart that knowledge to you. Hospital based, you get morning report, noon conferences, and, for example, EM and surgery have a day devoted to lectures specifically for the residents and students in that specialty.
Our graduates have been placed in prestigious residencies (Johns-Hopkins, Mayo, etc.) and I don't see why you shouldn't (you've heard this before, your med school experience is what you make of it). Any other questions you want me to answer in a little more detail would be best answered privately.
Your offer is generous, but I would need to know what if any supplies are available and I could talk to Dr. Burdick. Again, thanks for your offer of help. Sorry for the length, I get like this after long flights. Again, my best wishes.
