4AT

Delirium Screening

For education. Check every result.

Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.

Fill in every field above, then select Calculate.

How it is calculated

4AT is free to use, needs no training and takes about 2 minutes, which is why it has largely displaced longer tools at the bedside. Delirium is a symptom, not a diagnosis - a positive score is the start of a search for the cause, not a reason to sedate.

About

A two-minute delirium screen needing no training. Delirium is a symptom, so a positive score starts a search for the cause.

The rest of Anatium

Lessons, flashcards, condition modules, the anatomy lab, clinical cases and the AI study assistant are free, and need an account.
