Abnormal level of arousal as a predictor of delirium and inattention: an exploratory study
Z Tieges, A McGrath, RJ Hall… - The American Journal of …, 2013 - Elsevier
Objective Abnormal level of arousal (LoA) and inattention are key features of delirium.
However, the extent to which abnormal LoA alone might predict delirium and inattention is
unclear. Here we tested the hypotheses that (1) patients with abnormal LoA have delirium,
and (2) abnormal LoA is associated with worse performance on tests of attention. Methods
Thirty acute hip fracture patients aged 64–97 years underwent assessments of LoA, delirium
status, and attentional functioning in the 24 hours before surgery and at 2–4 and 7–10 days …
