The 4AT is a brief tool for delirium detection designed for use in clinical practice. It is the standard tool for delirium detection in many countries. It is recommended in multiple guidelines and pathways.
\r\nIt incorporates the Months Backwards test and the Abbreviated Mental Test - 4 (AMT4), which are short tests for cognitive impairment. This provides basic cognitive testing, aimed at detecting moderate-severe cognitive impairment, alongside assessment for delirium. See https://www.the4at.com/guide.

\r\n \r\nAMT4 is not a full cognitive test and decisions should not be made on this basis. A high AMT4 score can indicate general cognitive impairment, but note that a low score does not rule out mild cognitive impairment.
\r\nThis item requires information from one or more sources – eg a GP letter, personal knowledge of the patient, key informant such as family member, deduction from other information in patient history (for example, if the patient is drowsy and usually functions independently, the clinician may decide that this indicates acute change). If you do not have sufficient information, leave this element blank and click on “Calculate.”
