Responding to Ten Common Delirium Misconceptions With Best Evidence: An Educational Review for Clinicians

Area of Science:

• Geriatrics
• Critical Care Medicine
• Neurology

Background:

• Delirium (acute confusion) is a prevalent and serious condition associated with adverse outcomes like mortality and cognitive impairment.
• Effective diagnosis and management are essential for improving patient care and outcomes, yet a gap exists between evidence and practice.
• Over one-third of delirium cases are preventable, highlighting the need for improved clinical approaches.

Purpose of the Study:

• To review and address 10 prevalent misconceptions regarding delirium recognition, etiology, natural history, and management.
• To provide evidence-based responses to common misunderstandings about delirium.
• To bridge the gap between current evidence and clinical practice for delirium care.

Main Methods:

• An educational review of 10 common misconceptions about delirium.
• Presentation of best evidence to counter each misconception.
• Discussion of themes related to delirium detection, causes, persistence, and treatment.

Main Results:

• Casual observation is insufficient for delirium detection; validated screening tools and neurocognitive testing are necessary.
• Delirium is often multifactorial and can persist post-resolution of acute causes due to cognitive vulnerability.
• Long-term cognitive impairment is common after delirium, with patients not always returning to their baseline.

Conclusions:

• Challenging misconceptions about delirium can significantly improve patient care, quality of life, and clinical outcomes.
• Nonpharmacological management is the first-line approach for delirium prevention and treatment.
• Routine use of psychotropic medications for delirium is not recommended, reserved only for severe symptoms.
