I was going to muse over the management of acute confusional states (that nowadays seems to be called delirium, again).
There're the causes of it.
There's the assessment of it, through history and examination and investigations.
There're the interventions (both pharmacological and non-pharmacological).
But on balance I truthfully could not put it better, or more succinctly, that Nurse Anne who undeniably has the truth of it, here.
She's absolutely right.
