Delirium in intensive care unit patients

Area of Science:

• Critical Care Medicine
• Geriatrics
• Neuroscience

Background:

• Delirium is a common yet underdiagnosed condition in intensive care units (ICUs) and post-cardiothoracic surgery.
• Historically underestimated, delirium is now recognized to increase complications, hospital stay duration, and mortality.
• Effective detection and management strategies are essential for improving patient outcomes.

Purpose of the Study:

• To highlight the prevalence and significance of delirium in critical care settings.
• To review current detection tools for delirium in the ICU.
• To discuss management strategies and the need for further research.

Main Methods:

• Review of existing literature on delirium in critical care and post-surgical patients.
• Examination of validated delirium detection tools like the Confusion Assessment Method for the ICU (CAM-ICU) and Intensive Care Delirium Screening Checklist (ICDSC).
• Analysis of current management approaches, including nonpharmacological and pharmacological interventions.

Main Results:

• Delirium is frequently observed in ICUs and after cardiothoracic surgery, often missed by healthcare professionals.
• Tools like CAM-ICU and ICDSC aid in routine delirium screening by non-psychiatric staff.
• Management involves addressing underlying causes, employing nonpharmacological methods, and symptomatic treatment.

Conclusions:

• Delirium is a significant complication in critical care, necessitating improved diagnostic and management protocols.
• Routine screening using validated tools is recommended for early detection.
• Further high-quality randomized controlled trials are needed to establish optimal pharmacological treatments for delirium.
