Detecting delirium in Parkinson's disease: an evaluation of diagnostic accuracy of bedside tools.

ABSTRACT:

Background

Delirium is a serious, acute neuropsychiatric condition associated with fluctuating attention and altered arousal. Delirium in Parkinson's disease (PD) is common but often missed in hospital due to shared clinical features. This study aimed to evaluate the accuracy of current tools used to identify delirium in inpatients with PD.

Methods

People with PD admitted to all hospital wards were invited to take part. Participants completed a standardised delirium assessment based on the Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-5) criteria, in addition to standard bedside tools including the 4 As Test (4AT), arousal and cognition. This was a secondary analysis of a prospective observational study; bedside tools were not completed independently
