Undiagnosed delirium is common and difficult to predict among hospitalised patients

摘要

Previous research on delirium prevalence in hospital settings suggests it is a common condition which can affect around 20% of older people. Although delirium is both preventable and treatable, healthcare professionals often lack the necessary knowledge and skills regarding delirium prevention, identification and management. This has led to high rates of undiagnosed delirium, estimated to be as high as approximately 50% in the general hospital setting. The aim of the study was to analyse the prevalence of undiagnosed delirium and the determinants of undiagnosed delirium of patients referred to a large tertiary hospital in Australia.
