About this course
The 4AT is a short test for delirium and cognitive impairment. It has four items, takes about two minutes and needs no special training.
This course shows how to give and score the 4AT through 12 illustrated cases. The cases cover each item: alertness, the AMT4 (four short questions: age, date of birth, place and current year), attention (the months of the year backwards) and acute change or fluctuating course. You see how the item scores add up to a total from 0 to 12. On the 4AT form, a score of 4 or above means possible delirium, 1 to 3 means possible cognitive impairment, and 0 means delirium or severe cognitive impairment is unlikely, although delirium is still possible if the information on acute change is incomplete.
The course takes 35 to 45 minutes. It ends with a ten-question self-test with explanations, and you can then print or save a completion certificate. There is no account and no fee.
The course was written by Professor Alasdair MacLullich, University of Edinburgh, who developed the 4AT. The 4AT form, its instructions and the research papers are on the4at.com.
