ICU delirium was positively associated with impaired information processing speed and executive functioning at six-months post-discharge for this cohort.

Testing for cognitive impairment with RBANS and TMT should be considered due to its greater sensitivity in comparison to the MMSE.

Of 148 enrollees, 91 (61%) completed assessment at three and/or six months.

Incidence of delirium was 19%, with 41% cognitively impaired at three months and 24% remaining impaired at six months.

Delirium was associated with impaired cognition at six-months: mean TMT Part A scores were 7.86s longer than those with no delirium, and mean TMT Part B scores 24.0s longer.

Prospective cohort study conducted in a tertiary level ICU in Queensland, Australia.

Adult medical and surgical ICU patients receiving ≥12h mechanical ventilation were assessed for delirium on at least one day.
