  1. CAM-ICU = Confusion Assessment Method for ICU
  2. GAD-7 = Generalized Anxiety Disorder-7
  3. aEach item scored as 0, not at all; 1, several days; 2, more than half the days; 3, nearly every day
  4. bScored as present/absent
  5. cSour Seven is scored out of 18; cutpoint of 4
  6. Ordinal logistic regression (cumulative logit) of ordered GAD-7 items; Odds ratio above 1 indicate trend towards item score 2 or greater among family caregivers of patients with delirium
  7. Models adjusted for family age, family sex, family education, and patient Acute Physiology and Chronic Health Evaluation II score (dichotomized at median value)
  8. All values represent odds ratio with 95% CIs
