Does anyone know which are the 4 year programs (integrated with internship)? What are the major pros and cons of the 3 vs. 4 year? Thanks!
I'd say the 3 vs. 4 year debate mostly depends on what you want to do with your intern year.
In my opinion, categorical (4 year) programs are more desirable. The schedule of the intern year is most likely designed by the program director to include what he or she thinks is important to anesthesia training. It may include a month of anesthesia, also. You will likely meet and work with your anesthesia classmates and develop friendships early on. This is nice because anesthesia is more of an individual specialty: after you become a CA-1, you'll mostly work with only your attending and less so with your classmates. The transition from intern to CA-1 year is probably more smooth.
The advanced (3 year) programs don't have these advantages. The only advantage I see to an advanced program is the flexibility of picking your internship. For example, want to do that cushy transitional year in San Diego? You have that option.
When you rank your programs for the rank list, you will rank advanced spots and categorical spots separately. For example, my main rank list could look like:
1. Categorical at Program A
2. Categorical at Program B
3. Advanced at Program A
4. Advanced at Program B
Similarly, programs who offer both categorical and advanced spots submit a rank list for each of their categorical and advanced programs. Back when I was interviewing for residency, I was told that they usually don't prefer one over the other, meaning they won't rank you higher if you want to do their categorical program over their advanced. They usually submit the same rank list for both programs.
