I have seen that book in my dean's office -- the one that talks about the open spots in a field. If I remember correctly, there aren't a WHOLE LOT in anesthesia. When I told my Dean I was looking mostly on the West Coast she told me there were very few scramble spot available and told me to cast my net wider.
Anyway, I can see pros and cons to doing either of your options, here are my two cents worth:
1. If you only do a preliminary position, don't the programs that you interviewed at have to rank you for their preliminary list and thus you should contact them ASAP and let them know? Also, some programs have completely different interviews and program directors for the prelim medicine year, e.g. UC-Irvine.
2. If you do a prelim year, then the program knows that they will have you for only one year. If you know at this point that you do not want to be a categorical resident in IM...it's not very nice to take that spot from who actually want to be categorical. Then you will leave after a year and leave a spot unfilled for the program.
3. People switch into Anesthesia from different fields all the time. In my 9 anesthesia interviews this fall/winter, I met at least 6 or 7 people who were switching. They were looking for a CA-1 spot to start in 2009. I guess they were planning on taking time off in between. The advantage to actually going to the interviews (especially if you are a competitive candidate) is that you will have YOUR choice of the program you want to go to...instead of whatever is left over. However, if you go through the match again, you will be losing a year.
4. Looking outside the match for a CA-1 position starting in summer of 2009 during your intern year. I know that there are tons of programs across the country that leave some spots out of the match to make room for residents to switch into anesthesia (when they see the light). I was told at UCSF that even though they have 25 spots per year, they tend to leave 3 or 4 of them open for "out of the match." If you were able to get a spot out of the match, you could not have to take time off. However, it will be hard work to go through this all again during your intern year. You will have to leave vacation time to go to interviews.
5. Scrambling -- how easy is it to scramble into a field that you didn't have an intention of going into in the first place? I think it's fairly easy with things like Family Practice and Internal Medicine because there are so many open spots to scramble into. However, with anesthesia, it doesn't seem like there are that many spots and you make me competing with U.S. Senior who didn't match into Anesthesia and already have anesthesia personal statements, LORs, and connections to make calls for them.
...just my opinion. If I were you, I would probably just match into an intern year with internal medicine (but probably rank categorical too...so that you're not scrambling for something for even the first year!) Then I guess it would be worth a shot to try to scramble into an anesthesia program. I would have an anesthesia personal statement and a LOR handy for March 20th. If that didn't work, I would start sending emails to programs in the Fall of 2008 inquiring about open positions and try to interview during my intern year to procure a CA-1 position for 2009.
Good luck!
I got a copy from my dean's office. I don't know if there is an online source.
To answer the other posts. I want to do anesthesia, but it's basically too late for this match. I have been advised by some people to do categorical medicine and quit if I get an anesthesia spot as CA1. Others have told me to just do prelim year and apply for CA1. I was just wondering if I go the prelim route, I might be able to scramble into advanced anesthesia spots and I didn't know how tough that would be. Because if I match into categorical medicine, scrambling won't be an option at all.
