Interesting thread and so many areas involved. I work in a big hospital and we too have every task now with complimentary tick sheets, for almost every single process. So much so that you spend more time doing the proof of the task than the task (or at least that is how it feels). Rather scarily I have seen people more worried about the tick box being done and not realising the task has not been completed or that they should have focussed on something else.
Sorry to hear about the stress it has been causing your DH and family Bath - my Dh has struggled alot with his environment as well.
