Delirium in Older Persons: Prevention, Evaluation, and Management

Area of Science:

• Geriatrics
• Neuroscience
• Critical Care Medicine

Background:

• Delirium is an acute, fluctuating disturbance of attention and cognition, affecting 11-25% of hospitalized older adults.
• It presents as hyperactive, hypoactive, or mixed subtypes and carries a significant financial burden.
• Risk factors include advanced age, comorbidities, surgery, and polypharmacy, complicating clinical diagnosis due to symptom overlap with dementia and depression.

Purpose of the Study:

• To summarize the key aspects of delirium, including its subtypes, prevalence, risk factors, diagnostic challenges, and prognostic implications.
• To highlight the importance of early detection and prevention strategies for delirium in inpatient settings.

Main Methods:

• Review of existing literature on delirium in older adults.
• Clinical diagnosis is emphasized, with the Confusion Assessment Method noted as a sensitive screening tool (94-100%).

Main Results:

• Delirium is associated with a threefold increased risk of mortality within one year for hospitalized patients with prolonged symptoms.
• Haloperidol is mentioned in the context of treatment, suggesting faster onset and fewer adverse effects.

Conclusions:

• Prompt recognition and intervention for delirium are essential due to its association with poor prognosis.
• Prevention and early detection strategies should be prioritized in clinical practice for hospitalized older adults.
