Missing an icon from Sara other than that its ready for review. @nicolashery 
The click target on the patient card is just the name, but the whole card changes color on hover. Can be a little confusing if you try to click the edges, it won't do anything.

We have the `<a>` element stretch the whole card on `PersonCard`, would be nice to have it like that too. A couple ways you can do that. I chose to actually replace the root element (`<div>`) with an `<a>` element if the card is clickable. You can also use padding and negative margins if you'd like to keep it a child and stretch it.
