Which patient characteristic is associated with delirium risk and should be considered in preoperative planning for elderly patients?

• A. Cognitive function
• B. Hair color
• C. Eye color
• D. Height

Answer: (A)

Baseline cognitive function is a key predictor of delirium risk in elderly surgical patients. Delirium is an acute brain dysfunction that often occurs after surgery, especially in those with reduced cognitive reserve. When someone already has impaired cognition or dementia, they have less reserve to cope with the stress of anesthesia, infection, dehydration, sleep disruption, and multiple medications, making delirium more likely. Because of this, assessing cognition before surgery helps identify high-risk individuals and guides planning. This includes choosing analgesia and sedation approaches that minimize delirium risk (for example, multimodal pain control and avoiding or limiting benzodiazepines and anticholinergic drugs), ensuring proper hydration and electrolyte balance, correcting sensory deficits (like providing glasses or hearing aids), and arranging enhanced postoperative monitoring with strategies to reorient and engage the patient, encourage early mobilization, and involve family to support recovery. Other physical traits such as hair color, eye color, or height do not influence delirium risk and are not relevant for preoperative planning.
