[Delirium in the intensive care unit].

Area of Science:

• Critical Care Medicine
• Neuroscience
• Geriatrics

Context:

• Delirium is a prevalent condition in intensive care units (ICUs), with reported incidence rates ranging from 16% to 89%.
• Established detection tools like the Confusion Assessment Method for the ICU (CAM-ICU) and the Intensive Care Delirium Screening Checklist (ICDSC) offer high sensitivity and specificity.
• Current management strategies involve addressing underlying causes, implementing non-pharmacological interventions, and utilizing symptomatic drug therapy.

Purpose:

• To highlight the significant prevalence and adverse outcomes associated with delirium in the ICU setting.
• To underscore the need for further research into the prevention, early detection, and treatment of ICU-acquired delirium.
• To emphasize the importance of validated screening tools for accurate diagnosis.

Summary:

• Delirium frequently impacts ICU patients, significantly worsening prognosis and increasing mortality.
• Effective detection tools, such as CAM-ICU and ICDSC, are available for ICU settings.
• Treatment involves addressing root causes, non-pharmacological approaches, and symptomatic drug therapy.

Impact:

• Patients experiencing delirium in the ICU face a poorer prognosis, higher complication rates, prolonged hospital stays, and increased mortality.
• The high incidence and severe consequences of ICU delirium necessitate focused research for improved patient care.
• Further investigation into prevention, early detection, and treatment strategies is essential to mitigate the negative impact of delirium.
