Study Notes
Delirium Definition and Characteristics
- Delirium is a temporary, acutely altered mental state with fluctuating symptoms.
- It involves impaired consciousness, reduced awareness, decreased attention, and cognitive impairment.
- It often occurs around injury, infection, or hospitalization, particularly in older individuals.
- Delirium is associated with increased hospital stays and higher fall risk.
- Prevalence in burn patients and ICU patients is estimated at 9%–13%. A significant number of cases (66%–84%) go unrecognised.
Diagnosis and Identification
- Early diagnosis and identification of underlying causes are crucial for reducing delirium severity and complications.
- Most US critical care units (including burn centers) routinely screen for delirium
- Nurses are often the first to notice early signs of delirium due to close patient contact.
- Screening tools like the CAM-ICU and ICDSC are used.
- Immediate reporting of suspected delirium to the entire care team (physician, psychologist/social worker) is essential.
- Multiple factors often contribute to delirium.
Prevention Strategies
- Proper positioning (especially for bed-bound patients) helps prevent delirium.
- Maintaining a regular sleep-wake cycle during hospitalization is important.
- Appropriate lighting (day/night) contributes to delirium prevention.
- Encouraging ADLs (activities of daily living) and therapy during the day is beneficial.
- Educating family members about delirium is vital, as it can be distressing for them to observe.
