Controlled pre–post mixed-methods study to determine the effectiveness of a national delirium clinical care standard to improve the diagnosis and care of patients with delirium in Australian hospitals: a protocol

摘要

IntroductionDelirium, an acute confusional state, affects up to 29% of acute inpatients aged 65 years and over. The Australian Delirium Clinical Care Standard (the Standard) contains evidence-based, multicomponent interventions, to identify and reduce delirium. This study aims to: (1) conduct a controlled, before-and-after study to assess the clinical effectiveness of the Standard to improve diagnosis and treatment of delirium; (2) conduct a cost-effectiveness study of implementing the Standard and (3) evaluate the implementation process.
