In evaluating delirium, which source provides insight into cognitive baseline prior to illness?

• A. The physician's notes only.
• B. The family’s report of prior cognition.
• C. The patient’s current self-report only.
• D. The patient’s charted cognitive baseline.

Answer: (B)

Knowing the patient’s cognitive status before the current illness is essential in delirium assessment because delirium is an acute change from the person’s baseline. The family’s report of prior cognition is the best source because they observe how the patient functioned in daily life before illness and can describe long-standing memory, orientation, problem-solving, and daily abilities. This helps distinguish an acute delirium from chronic cognitive problems like dementia and shows how much the patient has changed. Relying on the patient's current self-report is often unreliable in delirium, since the condition can impair attention, memory, and awareness, making self-perceptions inaccurate. The physician’s notes or the charted cognitive baseline may contain useful information, but they’re not consistently complete or up-to-date regarding pre-illness functioning. So the family’s account provides the most practical and accurate glimpse of what the patient’s cognition was like before the current illness.
