Figure 1.

Daily rates of delirium, coma, or without delirium/coma status as assessed up to first 14 d of ICU stay (n = 268). Number above each bar column indicates number of patients assessed per day. Daily percentages do not equal 100% due to incomplete assessments, death, or discharge from ICU. Delirium was defined as a positive Confusion Assessment Method for the ICU (CAM-ICU) assessment on either morning or afternoon assessment. Coma was defined by Richmond Agitation-Sedation Scale (RASS) score of –4 or –5. Without delirium or coma was defined by RASS greater than –4 and a negative CAM-ICU on either morning or afternoon assessment.
