Delirium is defined by the National Institute on Aging as "a state of sudden, acute confusion." The most common occurrence of delirium is during a hospital stay. Individuals who already have dementia are more likely to struggle with delirium. Delirium also can worsen the progression of dementia. For individuals who do not have dementia, having delirium can increase the chance of developing problems with memory and understanding at a later date. It is estimated that 25% of adults who are age 65 or older have delirium while hospitalized for an acute illness or following a surgery. The numbers are even higher for a patient who is in the intensive care unit age 65 or older where delirium happens in 80% of this population.
Preventing delirium is important, because those who suffer from delirium are more likely to have a harder time recovering from an injury or illness. They are also more likely to require going back to the hospital for further care, and are at an increased risk of falling which can all worsen the chances of recovery.
One thing the researchers studied was testing to see if using less sedation medication/anesthesia during a surgery would lessen the rate of delirium. This method did not prove to have a significant impact on the rate of delirium.
The most helpful method to reduce delirium that was found over the course of this study, was several methods described by the Hospital Elder Life Program. These include the following:
