Delirium in Cardiac Intensive Care Unit

Area of Science:

• Critical Care Medicine
• Neuroscience
• Surgical Outcomes

Background:

• Delirium is an acute brain dysfunction frequently observed in post-cardiac surgery patients.
• Post-operative Delirium (POD) prevalence varies (11.4%-55%) based on diagnostic tools and study type.
• The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and Intensive Care Delirium Screening Checklist (ICDSC) are standard diagnostic tools.

Purpose of the Study:

• To highlight the underdiagnosis and significance of delirium in the Cardiac Intensive Care Unit (CICU).
• To review risk factors, consequences, and management strategies for delirium in CICU patients.
• To emphasize the need for further research into delirium management in CICU.

Main Methods:

• Review of existing literature on delirium in post-cardiac surgery patients.
• Classification of delirium risk factors into modifiable, non-modifiable, and surgical categories.
• Evaluation of non-pharmacological and pharmacological interventions for delirium.

Main Results:

• Delirium in CICU is underdiagnosed despite significant associated risks.
• Delirium is linked to increased mortality, prolonged hospital stay, functional decline, and higher costs.
• Non-pharmacological strategies (e.g., medication review, early rehabilitation, sleep hygiene) demonstrate benefits.

Conclusions:

• Delirium in CICU is a critical issue with severe patient outcomes.
• Non-pharmacological interventions are effective in reducing delirium incidence.
• Limited pharmacological options necessitate further investigation and development for CICU delirium.
