Prevention

The most successful approach to preventing delirium is to target risk factors that might trigger an episode. Hospital environments present a special challenge — frequent room changes, invasive procedures, loud noises, poor lighting, and lack of natural light and sleep can worsen confusion.

Evidence indicates that certain strategies — promoting good sleep habits, helping the person remain calm and well-oriented, and helping prevent medical problems or other complications � can help prevent or reduce the severity of delirium.
