While Microsoft has a large footprint in healthcare IT (and so do mainframes), SaaS is huge and becoming even more important, and there the server OS doesn't matter much to the customer.

That said, what Apple announced was patient data collection support in the client OS. App developers take care of shipping it to physicians and hospitals. Apple isn't taking the patient's information the last mile to physicians themselves.

Disclosure: I'm a co-founder of a startup dedicated to improving mobile patient and physician communication (Care Thread, http://www.carethread.com). We already integrate with hospital and doctor's office workflows, and we've been looking forward to the introduction of this feature in order to collect relevant patient data.
