Yup - we have something kind of like this too. One of my resident-mates is technically sponsored by an outside cardiopathology lab, so she does residency but works there too. We will have an incoming resident next summer who is sponsored by the state diagnostic lab, so she will spent more rotations over there, too. I think due to funding issues, some programs are trying to find funding from outside sources for residents, who then take more specific training courses. My one caveat is that while "specializing within your specialty", you would still need to complete the same requirements as all the other residents - which is a LOT of work when you technically have "two employers". Very rewarding, but very busy. My cardiopath colleague is learning this firsthand.
When they say strongly encourage, they mean it in most cases. Yes, if someone wants to do a PhD and you say outright that you are not sure, then they will consider the other person more heavily. Unfortunate fact. Some programs definitely do pressure you.
The proper response is that at this time, if they were to ask you, is that you see "no impediment" to it "right now", and "are interested" in a PhD. Not that you will do one 100%. Don't paint yourself into a corner you cannot get out of unless you are very sure you want to do one, but never openly admit to being unsure. I know it sounds bad but....eh.
This is something to definitely speak directly with the residents about, and ask them specifically if they feel pressured. Sometimes "strongly recommended" means they will beat you with the proverbial stick to get it - occasionally, it is a lot more lax and they understand that people's desires change.
If you have questions about specific programs, you can PM me, just do I don't go blathering on a public forum - I already blathered on more than I should have about one particular one
I know about a few, including ones my fellow residents have told me about. Also - definitely ask about the boards situation with regards to PhD. I know programs that do not allow you to take boards until you finish your PhD - which means 3-4 years of doing no diagnostics. Poor setup, IMO.
Necropsy by itself is not the biggest part of it anyway - the vast majority of programs are very histology based. Sure you do necropsy, but you do histo on all your cases (or a lot of them) plus biopsy duty, etc.
In order to get as much histology experience as possible, rounds and seminar are absolutely essential. Make sure the program has structure for their residents to learn. Some programs skimp by on maybe one seminar a week with a couple slides - no way.
We get blasted with histology here
Here is an example rounds schedule here (and I will say that, with the national first-time pass average of ACVP boards being ~30%, and it being 90-100% here, this just shows you how much our extensive structure helps).
Monday:
8:00am Derm path slide rounds or journal club
Tuesday:
11:00am State diagnostic lab slide rounds (every other week - we are given 15 slides ahead of time, must fully describe, and then go around the room on the multiheaded scope and present to the group)
Wednesday:
off
Thursday:
11:00 am AFIP rounds (we all gather together and are randomly called on to describe a slide we have never seen before at the multiheaded scope, in front of everyone, in only 15 minutes - VERY good boards practice!!)
Friday:
10:00am Gross quiz - we are presented with 20 images, 30 sec per image, and must come up with a morphologic diagnosis, cause, pathogenesis, whatever the pathologists wants. Then we go around the room and say what we think it is.
11:00am Histopathology seminar: We get 3 -4 slides every week, and again are randomly called up to present. Our writeups are also graded.
1pm Gross rounds : showing everyone what we did in necropsy that week.
So you see, we do a TON of histopath!!!
And this is in addition to all the histopath you do on your necropsy cases and biopsy. I know a lot of other programs are just as nicely structured, but some kind of leave you to fend for yourself. I can only speak a little about a few other program on that account, so again your best bet might be contacting actual residents.
I still say one of the biggest things in residency is liking your colleagues. I don't like Texas, but I am truly so happy to be with such a friendly group of people. Even in our rounds (which can often be embarrassing if you dont know what you are looking at! lol) we always encourage each other, help, etc.
