    Title: Delirium - are we really looking for it?

    Delirium has long been recognized as a common disorder of the geriatric ED population (seen in up to 20% of patients above the age of 65 years), but how good are we at detecting it?

    Studies show that the diagnosis of delirium is made in the ED in only 11-46% of patients, which means that more than half go undiagnosed. The problem is, the risk of death at 3 months increases by 11% for every 48 hours of delirium the patient experiences, and so does their length of stay and functional decline. It is mostly missed in patients who have a baseline cognitive dysfunction, such as dementia.

    So what can we do about that?

    Treat delirium as a neurolgical emergency; be vigilant about diagnosing it and treating it. There are a lot of neurocognitive tests that can be used for diagnosis (such as the mini-mental status exam), but they are usually too cumbersome to use in an ED setting. The CAM (Confusion Assessment Method) has been extensively studied and has a sensitivity and specifity of about 95% to diagnose delirium. It includes the acuity of onset, fluctuant course, inattention (the hallmark), disorganized thinking and/or altered level of consciousness.

    Bottom Line? Don't forget to screen your elderly patients for delirium and treat them accordingly!
