As an aside from the main thrust of the thread, medical communications can be quite a challenge.
I have a friend who has had some big medical problems over the past few years and they've taken a lot out of her.
And the post is completely buggered where she lives.
She forgets to charge her landline handset. Or puts it down... somewhere. Forgets where.
Ditto, mobile.
Oh and there is some back end issue with O2 where it says she's not available when she is, for some time after any previous call (SUPER).
She rarely checks her emails. I went round once and found the phone had had a problem connecting to the WiFi for a week and when I fixed it, a whole bunch of emails came through.
Messages - ditto.
When the post comes through (late and in huge batches) it piles up unopened for an indefinite period.
When she does speak to someone on the phone, or read an email, or a letter, there's a good chance she'll forget or confuse the details afterwards.
Like... imagine running your life when you're floored by flu, but it's like that all the time.
Mix all that up with the normal chaos that is hospital appointments (we once found 2 letters informing her of a) an in-person appointment b) a telephone appointment on the same time and day and with the same department ).
And it's a miracle any communication ever takes place!
