You typically won't have your data in too many other systems unless you are hopping between different medical groups/hospitals. There's just a possibility that the above could happen because, seeing and making the sausage, I wouldn't trust anyone to be able to tell me who has seen my health records.

The providers I've seen have had my records online since at least 2015 so this regulation doesnt really affect me much. You just have to know who what and how to ask.
I can see something like this negatively impacting what doctors say to each other.
as "Now let us (let's) delete them"
I think his meaning was "give us the right to delete them" which IMO should be the standard.
I'm not arguing against the sentiment (and indeed I think patients should have a much stronger ability to audit and control how their records are shared, including the ability to opt out of sharing) -- but when it comes to records retention by the originating organization, it's important to evaluate these practices in the broader context.
