Note: Patient delirium burden and Caregiver delirium burden samples are partially overlapping; 247 patients and 213 family caregivers completed the burden assessment at Month 1; 193 patient-caregiver dyads completed both burden instruments. Missing data: Information on education was only available in 264 patients, any ADL impairment in 264, any IADL impairment in 181, Caregiver relationship to patient in 238, and Caregiver lives with patient in 238. All other variables had no missing data for the 267 patients with patient and/or caregiver burden data. ADL = Activities of Daily Living; IADL = Instrumental Activities of Daily Living, Dementia = proxy Informant Questionnaire of Decline in Elderly (IQCODE) score ≥ 3.5 or chart-based diagnosis of Alzheimer’s disease or dementia.
