Which strategy reduces postoperative delirium risk in older adults?

• A. Sleep optimization
• B. Increase opioid dosing
• C. Isolation
• D. Avoid analgesia

Answer: (A)

Disruption of sleep-wake cycles after surgery is a major contributor to delirium in older adults. Sleep optimization helps stabilize the brain’s circadian rhythm, reduces nighttime disorientation, and supports better attention and orientation as the patient recovers. Practically, this means limiting nighttime awakenings, controlling noise and light, maintaining a comfortable environment, and coordinating analgesia so that pain relief doesn’t excessively sedate or disturb sleep. In contrast, increasing opioid dosing can worsen delirium through CNS depression and cognitive effects; isolation deprives the patient of sensory input and cues, which can confuse the brain; and avoiding analgesia can cause pain and stress that heighten delirium risk. Therefore, focusing on sleep optimization best reduces the likelihood of postoperative delirium in older adults.
