Delirium in Surgery: High Rates, Big Impacts

Postoperative delirium is a common and serious complication affecting surgical patients, significantly influencing outcomes and care.

• Delirium occurred in 10.6% of screened patients; those affected were older and had higher comorbidity rates.
• Key predictors include dementia (37% vs 7.9% in non-delirium), urgent surgery (55% vs 26%), and each 10-min increase in surgery time raises delirium odds by 2.3%.
• Delirium is linked to a 3.2-fold increased risk of 30-day mortality and substantial declines in independence and discharge status.

Standardized delirium screening is essential for improving patient outcomes in surgical settings.
