Structured PICO

Does providing detailed preoperative statistical anaesthetic-risk information improve knowledge without increasing anxiety in patients scheduled for general anaesthesia?

P
Population
40 (ASA Class I or II) patients scheduled for surgery requiring general anaesthesia
I
Intervention
Detailed information about anaesthesia risks provided on the eve of surgery
C
Comparator
Routine information
O
Outcome
Levels of anxiety (assessed by the Spielberger State-Trait Anxiety Inventory) and actual knowledge of risks (assessed by a special visual analogue scale)patient reported

Providing detailed statistical risk information about general anaesthesia improves patient knowledge of rare complications without increasing anxiety.
