When I interviewed at Touro-NY a few months ago, the dean mentioned that AUC bought out their prior rotation slots at Bronx Lebanon. So Touro students would no longer be able to rotate there. I think the Bronx had been Touro's main rotation hospital, so this was a major loss for them. As an applicant, this was one of my top reasons for declining my acceptance to TouroCOM. I found the remaining rotation hospitals to be unimpressive, as well as quite dispersed. I personally think that if Caribbean schools increasingly "buy out" these positions, it will not only restrict the opportunities for New York medical students to train, but will eventually shoo applicants away from New York medical schools. Maybe not Cornell, NYU, or Columbia, but some of the "less prestigious" (this is debatable, I know) MD and DO American medical schools. I can personally say that AUC's big purchase of prior DO rotation spots is what made me decide to go elsewhere.
I do, however, understand that the Caribbean schools need to train their students somewhere. But why are they so concentrated in New York? Maybe there should be a cap on the number of spots allowed? It seems that in one way or another their purchasing power needs to be regulated.
