Overview
Delirium is caused by variety of causes but likelihood of having delirium depends on various risk factors.
Risk Factors
Common risk factors associated with delirium include:[1]
- Older age
- Dementia
- Hypertension
- Emergency surgery or trauma before ICU admission
- Acute Physiology and Chronic Health Evaluation II (APACHE-II) score
- Mechanical ventilation
- Metabolic acidosis
- Delirium on the prior day
- Coma
Modifiable Risk Factors
- Immobilization due to catheters insertion or restraints
- Medications such as sedative hypnotics, narcotics, anticholinergic drugs, corticosteroid, polypharmacy
- Withdrawal of alcohol or other drugs
- Acute neurological impairment such as acute stroke (right parietal), intracranial hemorrhage, meningitis, encephalitis
- Infectious disease, iatrogenic complications, severe acute illness, anemia, dehydration, poor nutritional status, fracture, trauma, HIV infection
- Metabolic impairment
- Surgery
- Intensive care unit admission
- Pain
- Emotional stress
- Lack of sleep
Non-Modifiable Risk Factors
- Cognitive impairment
- Older age (>65 years)
- History of delirium, stroke, neurological disease, falls or gait disorder
- Associating multiple medical aliments
- Gender: Male over females
- Renal or hepatic pathology[2]
