The LECOM-SH sites are the same as the LECOM-Erie sites. As far as I have been told both campuses get put in the same pool for rotations. From what I've heard there were never a ton of UPMC spots except at Hamot, McKeesport, and maybe Mercy. That said, it sucks a lot for the people from Pittsburgh who wanted to do some UPMC rotations. Beyond that, I doubt it will affect students that much. UPMC was never a 13, and so cores were/are still done at completely different hospitals. LECOM continues to get more spots at other hospitals (but your guess is as good as mine as to the quality of those rotations). In general though, they seem to be moving toward a system of more "13s" (single hospitals/systems where students can complete all of their core rotations). Again, I don't know if this is good or bad. I believe they have a list of rotation sites somewhere online if you want to look into it.
I will say that for those that I know who had done 2 or so rotations at UPMC, they said they were very good experiences. Plus, I can't imagine anyone would be happy to lose sites, but I doubt there will be a huge effect in the long run. We'll have to see what happens to the current second years when they start in June to know for sure if there are any major repercussions.
