Sleep Disturbance in Older ICU Patients

In this study, the authors note aging is associated with specific changes to both the quantity and quality of sleep and that these changes make it hard to adjust sleep and wake rhythms to changing environmental conditions. In the context of the ICU, an environment already known to alter sleep, the authors evaluated sleep in patients admitted to the ICU who were older than age 80. The authors reviewed four studies on sleep in the elderly. This study was helpful in bring much of the resaerch of sleep in elderly ICU patients into one location. However, much is still needed in the study of sleep in this frail and vulnerable population.
