Risk factors associated with acute in-hospital delirium for patients diagnosed with a hip fracture in the emergency department.

CLINICIAN'S CAPSULE What is known about the topic? Delirium, or acute confusion, occurs in up to 62% of patients who have experienced a hip fracture. What did this study ask? What risk factors are associated with acute in-hospital delirium for ED patients diagnosed with a hip fracture? What did this study find? History of neurodegenerative disease or dementia, age>75 years, and absence of analgesia in the ED were associated with acute in-hospital delirium. Why does this study matter to clinicians? Although many variables associated with delirium may not be easily modified, more careful attention to ED pain management and the provision of better analgesia are important.
