Hippuppy.
Here are a couple things I want you to think about.
It seems clear that you understand the severity of your father's disease.
Looking for "the best" institution is noble, and something I'd try and find too if it were my father.
I just want to maybe help redefine what "the best" may be for him.
It's not just about getting transplanted; it's also about the recovery, rehab, and also the waiting.
Lungs are temperamental organs that result in a lot of patients getting called in and then cancelled when the lungs turn out to be crap.
The recovery can be smooth, but it's not short.
The waiting period can be long, depending on where he falls on the waiting list.
the point I'm trying to get at is, I want you to think of all the scenarios involving his condition: getting a transplant, the operation, possibly not getting transplanted, the waiting, the recovery. Put all these together and now ask yourself where you think he'd be more comfortable staying (location wise), and where would also give him the best access to family/support networks.
I went to Columbia, I think they're fairly solid with lungs, but it's in Manhattan.
Putting him in position for a transplant there would mean relocating, and possibly being far from the rest of his family (jumping on a plane with end stage IPF for a transplant isn't gonna happen, so he'll need to be local and drivable).
If he gets transplanted there, what's his recovery going to be like, how much will family be able to visit/help.
If he spends a lot of time waiting, what's his quality of life going to be like while he's there (washington heights isn't Atlanta)?
There are a lot of good institutions to do a transplant at. Just take into consideration what your choice may mean in other scenarios too.
If you're going to Penn, Pitt won't be so far away (300 miles +/-) so you'd be closer, but Emory is going to be right next to home, which would mean he'd keep his existing care team and social/family support network.
