The UK National Institute for Health and Clinical Excellence has just published its guidelines “based on best available evidence” on delirium.  The full document has 662 pages but there is a summary as well as guidance for patients and carers.  They recommend routine screening for delirium in critical care and post-anaesthetic recovery areas.  In this author’s opinion, the conclusion regarding pharmacological treatment disappoint but you will of course make your own mind up.
