ICU + post-op delirium prevention
Mnemonic device
ABCDEF
Mapping
A
Assess pain (CPOT, NRS); manage adequately
B
Both spontaneous awakening + breathing trials daily
C
Choice of analgesia + sedation — avoid benzos, prefer dex or propofol
D
Delirium assessment q-shift (CAM-ICU, ICDSC)

Clinical note: Bundle reduces delirium 25-30%, reduces ICU LOS, reduces mortality. Avoid benzodiazepines (delirium-prone). Treat hypoactive AND hyperactive delirium — hypoactive is often missed and has WORSE outcomes.
