Validation of the 4AT for assessing recovery from delirium in older hospital patients.

ABSTRACT:

Background

A crucial part of delirium care is assessing for recovery, yet there are no validated methods for this. The 4AT is a widely used delirium assessment tool, but its performance in assessing recovery remains unstudied. This study evaluated the 4AT's performance in assessing recovery from delirium.

Materials and methods

In this prospective diagnostic accuracy study, older hospitalised patients (≥70 years) with reference standard delirium on enrolment were assessed 2-4 times over ≤9 days. Paired researchers independently conducted blinded assessments of (i) a reference standard (Diagnostic and Statistical Manual for Mental Disorders, 5th edition), including the Delirium Rating Scale-Revised-98 and neuropsychological tests and (ii) the 4AT (index test, score ≥ 4 positiv
