Delirium Instruments
Dr. Sharon Inouye and colleagues have developed several instruments for the recognition and diagnosis of delirium. All instruments, training manuals, and recommendations for use can be accessed at the below links.
Confusion Assessment Method (CAM-short) – The Short CAM contains the 4 items of the CAM diagnostic algorithm. These are the first 4 items of the full 10-item CAM.
Recommended use: most widely used method for detection of delirium for both clinical and research applications. Should be scored on the basis of cognitive screening tests (e.g. SPMSQ or Mini-Cog).
Translations available in Arabic, Chinese, Danish, Dutch, French, German, Greek, Hebrew, Italian, Portuguese, Sinhalese, Spanish, and Swedish.
Confusion Assessment Method (CAM-Long) – This 10-item tool is the gold standard for delirium identification in research situations.
Recommended use: broad research and clinical applications. Considered the gold standard for rating delirium– including diagnosis, severity, and behavioral subtype.

FAM-CAM (Family Assessment of Delirium) – The FAM-CAM is designed to be used with family caregivers to enhance the recognition of delirium.
Recommended use: family assessment in research or clinical situations

3D-CAM (Brief Cognitive Screen with CAM) – The 3D-CAM is a 3-minute diagnostic assessment of delirium.
Recommended use: quick assessment of delirium in research or clinical situations
Ultra-Brief Confusion Assessment Method (UB CAM)- A two-step protocol with skip pattern involving a clinician-administered two-item interview (UB-2), followed, when positive, by a short interview (3D-CAM) and rating scale that uses verbal responses and observations by the rater to rate the Confusion Assessment Method (CAM) diagnostic algorithm. The following skip pattern is applied—as soon as one incorrect answer or positive patient symptom report or interview observation is positive, the remainder of the items in that CAM feature can be skipped.
