The Intensive Care Society (ICS) has released updated guidance titled Guidance for Delirium in the Critically Ill Patient . The document outlines current evidence, best practice and practical recommendations to support the prevention, detection and management of delirium in adult critical care.
Key recommendations include:
- Routine use of validated delirium screening tools such as CAM-ICU or ICDSC for all critically ill patients.
- Adoption of a multidisciplinary, non-pharmacological first-line approach, reserving medication only for situations where there is immediate risk to patient or staff safety.
- Early recognition and treatment of underlying causes, supported by structured assessment, communication and documentation.
- Implementation of a care-bundle approach, combining screening, prevention, and management interventions as part of daily ICU practice.
- Enhanced staff education, family involvement and leadership engagement to improve awareness and consistency in delirium care.
The guidance emphasises that delirium is both common and preventable, affecting up to 74% of ventilated ICU patients, and calls for a shift in focus from reactive management to proactive prevention.
