For patients with delirium, attempt to obtain a current and past history from other sources, including prehospital workers, family or friends, and past medical records. Look specifically for street drug, alcohol, over-the-counter or prescribed medication use. Consider preexisting endocrine disorders. Inquire about recent activities that may have resulted in exposure to toxins or environmental injury. Ask about prior psychiatric illness, history of overdose and similar episodes of confusion in the past.
