Distribution of scores on the Glasgow Outcome Scale (GOS).
A measure of functional neurological outcome, at hospital discharge and 3 months, 6 months, and 1 year after hospital discharge according to the presence or absence of delirium during hospital stay (i.e. ICU + hospital wards) (N = 159) (A.—D.) and in-hospital delirium burden (DB) (N = 107) (E.—H.) in mechanically ventilated intensive care unit patients. The GOS is a global 5-point scale for functional neurological outcome that rates patient status into one of five categories: 1, Dead; 2, Persistent Vegetative State; 3, Severe Disability; 4, Moderate Disability or 5, Good Recovery. In-hospital delirium burden ranges from 0.00 to 1.00 and is calculated by dividing the number of in-hospital (ICU + hospital wards) delirium days patients experienced delirium over the number of days patients were assessed for delirium. Low and high DB groups correspond to the low-tertile (N = 54, DB 0.000–0.111) and high-tertile (N = 53, DB >0.468–1.000) DB groups, respectively. The numbers in the bars are percentages of patients who had each score. The percentages may not sum to 100 because of rounding. The list of the number of patients according to their delirium status with each GOS score are provided in S2 Table.
