Non-pharmacological approaches in the prevention of delirium.

Delirium is a geriatric syndrome often occurring in hospitalized older patients. Since there is no established treatment for delirium, it is important to identify patients at high risk to develop it, to implement preventive interventions. As yet, there is no conclusive evidence that different drugs classes are effective in preventing delirium; whereas they have potentially severe adverse effects. The non-pharmacological interventions to prevent delirium are quite diverse, ranging from single-component interventions to complex multi-component interventions that deploy simultaneous care for different risk factors. The aim of this review was to summarize the evidence concerning the efficacy of non-pharmacological interventions in delirium prevention in older adults.
