Subtypes of delirium in critically ill patients with coronavirus disease 2019 (n = 268). Number above each bar column indicates number of patients assessed for delirium per day. Daily percentages do not equal 100% due to incomplete assessments, death, discharge from ICU, or screening negative for delirium. Number of patients screening positive for delirium per day: 65 (day 1), 92 (day 2), 87 (day 3), 98 (day 4), 93 (day 5), 93 (day 6), 99 (day 7), 95 (day 8), 87 (day 9), 75 (day 10), 81 (day 11), 72 (day 12), 61 (day 13), and 63 (day 14). Confusion Assessment Method for the ICU (CAM-ICU) and Richmond Agitation-Sedation Scale (RASS) assessments were performed up to bid while patient was admitted to the ICU. Hypoactive delirium was defined by RASS of –1 to –3 with positive CAM-ICU and hyperactive delirium was defined by a RASS score of +1 to +3 with positive CAM-ICU. Mixed delirium was defined as patients with both hyperactive and hypoactive delirium assessment on a given ICU day.
