ED-DEL: Development of a change package and toolkit for delirium in the emergency department.

Delirium is a common and deadly problem in the emergency department affecting up to 30% of older adult patients. The 2013 Geriatric Emergency Department guidelines were developed to address the unique needs of the growing older population and identified delirium as a high priority area. The emergency department (ED) environment presents unique challenges for the identification and management of delirium, including patient crowding, time pressures, competing priorities, variable patient acuity, and limitations in available patient information.

Association of CSF Alzheimer's disease biomarkers with postoperative delirium in older adults.

Introduction: The interaction between delirium and dementia is complex. We examined if Alzheimer's disease (AD) biomarkers in patients without clinical dementia are associated with increased risk of postoperative delirium, and whether AD biomarkers demonstrate a graded association with delirium severity.

Methods: Participants ( = 59) were free of clinical dementia, age 70 years, and scheduled for elective total knee or hip arthroplasties.
