Which tool is used for delirium assessment?

• A. Confusion Assessment Method (CAM)
• B. Mini-Mental State Examination (MMSE)
• C. Montreal Cognitive Assessment (MoCA)
• D. Beck Depression Inventory (BDI)

Answer: (A)

Delirium screening relies on detecting an acute, fluctuating change in attention and cognition. The Confusion Assessment Method is specifically designed for this purpose. It uses a quick, structured approach to identify delirium by looking for: (1) an acute onset and fluctuating course, (2) inattention, and then, if those are present, (3) either disorganized thinking or an altered level of consciousness. A positive assessment requires both core features plus one of the additional features, making CAM a sensitive and specific tool for delirium across hospital and ICU settings. The other tools focus on different domains. The Mini-Mental State Examination and the Montreal Cognitive Assessment screen general cognitive function and may miss the acute, fluctuating nature of delirium. The Beck Depression Inventory measures depressive symptoms, not delirium.
