Delirium measurement and screening tools

The Delirium Index and the Delirium Risk Screening tool are cornerstones of delirium prevention services.

• The Delirium Index is an instrument for the measurement of severity of symptoms of delirium that is based solely upon observation of the individual patient, without additional information from family members, nursing staff or the patient's medical chart.
• The Delirium Risk Screening tool allows nurses working in long term care to identify residents who are at increased risk of developing delirium. This tool predicts the future development of delirium among cognitively impaired residents initially without delirium.
