Forest plot of daily probability of delirium

All patients who had at least 90% delirium or coma assessments during their index ICU stay and 2 days of ICU stay were included in this analysis (n=2049). Other states, such as comatose, awake without delirium, deceased, and discharged (from index ICU) were considered as competing risks for this multinomial regression analysis. Risk factors with scores greater than 1 (and not crossing 1) were associated with a statistically higher risk of delirium the following day. ICU=intensive care unit. OR=odds ratio. SAPS II=Simplified Acute Physiology Score II. *For all continuous variables (age, SAPS II, proportion of ABCDE elements performed), comparisons shown in parentheses correspond to the 75th vs 25th percentile values for that variable. †p values shown represent the overall p values for the variable and are not associated with the level to level comparisons within these variables, which are represented by the 95% CIs. ‡Bundle element F was assessed separately since COVID-19 presents a unique circumstance in which in-person visitation was restricted at most of the participating sites.
