Atul Gawande's "Being Mortal" has a chapter or two on expectation gap, the realisation of how large it was made my stomach drop.

And do so once more when Gawande described how the expectation gap still existed when doctors become patient (both he and his father are doctors, after his father fell with cancer he first succumbed to the expectation gap as he was preparing a book on the subject).

It's a great, eye-opening book.
