PRINCIPLE 2: Delirium risk identification and prevention strategies
Older people will be assessed for delirium risk. Interventions will be put in place for prevention of identified risks. Identified risks will be communicated to the older person, their carer, family and staff involved in their care.
Delirium risk factors
Delirium is one of the most common, potentially preventable, adverse events for hospitalised older people.
A number of factors have been identified that can increase an individual’s risk of developing delirium. Early identification and modification of risk factors can prevent delirium or reduce its intensity.
