Older adults with comorbid conditions are particularly vulnerable to developing delirium in an ICU environment due to several key factors. The aging process itself can lead to changes in brain function, making older adults more susceptible to acute changes in mental status. Additionally, the presence of comorbid conditions—such as cardiovascular, respiratory, or metabolic disorders—can further compromise overall cognitive resilience.

In the stress of an ICU setting, where there are often significant changes in medications, environmental stimuli, and physical well-being, these individuals may have a reduced ability to cope with the physiological stresses, leading to an increased risk of delirium. Common contributing factors to delirium include metabolic derangements, infections, sleep disturbances, and the effects of sedative or analgesic medications employed in critically ill patients.

Understanding this demographic’s increased likelihood of developing delirium is essential for implementing preventive measures and effective management strategies in the ICU, thereby improving patient outcomes and overall care.
