Review articles: postoperative delirium: acute change with long-term implications

Area of Science:

• Geriatrics
• Neuroscience
• Anesthesiology

Background:

• Delirium is an acute change in cognition and attention, often affecting older patients, particularly those with pre-existing cognitive impairment.
• Postoperative delirium is linked to slower recovery, extended hospital stays, and increased healthcare costs.
• Its incidence varies based on surgical factors and assessment methods.

Purpose of the Study:

• To provide a comprehensive guide for assessing, preventing, diagnosing, and treating delirium in the perioperative setting.
• To highlight the importance of early risk identification and proactive management strategies.

Main Methods:

• Review and synthesis of current literature on delirium assessment and management.
• Emphasis on preoperative risk stratification and implementation of evidence-based prevention programs.
• Development of standardized treatment protocols for postoperative delirium.

Main Results:

• Delirium can persist long-term, leading to poor cognitive and functional outcomes.
• Care improvements, including preoperative risk identification and staff training, can mitigate delirium incidence.
• Standardized protocols and prevention programs are effective in reducing delirium-associated morbidity.

Conclusions:

• Proactive perioperative care, including risk assessment and targeted interventions, is essential for managing delirium.
• Implementing structured programs for delirium prevention and treatment can significantly improve patient outcomes and reduce healthcare burdens.
• Multidisciplinary collaboration is key to effectively addressing postoperative delirium.
