On Quora, by a medical professional:

I feel that Healthkit might well be the first step in creating something akin to a universal EMR. If Apple pulls this off with the right partners, they could potentially solve one of the single worst problems in healthcare today: the inability to easily transfer patient records from one care location to another.

This is where the opportunity lies. Not just is this incredibly exciting in itself, but by Apple creating partnerships with other industries that can benefit from Apple’s software and hardware Apple has the ability to leverage their pocketbooks. Just like Apple did with the cell carriers. It could become another subsidized market that can be made accessible to the consumers without ‘ads’ or other shitty workarounds.
