Paula Duncan saw how quickly it could happen with her father-in-law. When he was hospitalized with pneumonia at age 80, his personality changed. Almost overnight, he became aggressive and combative.
As a hospital nurse, Duncan knew that older patients sometimes become delirious. She just didn't know how common it was — or that anything could be done about it.
Now, she heads a program at Park Nicollet's Methodist Hospital that's trying to fend off these sudden, frightening bouts of confusion.
Surprisingly, it relies on a small army of volunteers and a little friendly conversation. What they discovered, Duncan says, is that a steady dose of "high touch, low tech" activities — doing crossword puzzles, reminiscing, talking about their grandchildren — can engage the minds of patients when they're most vulnerable.
And research shows it's helping elderly patients leave the hospital sooner and in better shape than their peers.
In the hospital world, it's no secret that older patients are prone to abrupt changes of behavior, Duncan says. They may seem perfectly normal at home, but once they're in the hospital, they may forget where they are, try to pull out their tubes, hallucinate.
For years, doctors and nurses tended to shrug off the problem, said Dr. Nima Desai, a staff doctor at Methodist. "It was kind of like, 'Oh, this is what happens in the hospital.' " Unlike dementia, it often clears up in a matter of days.
But in 1999, a groundbreaking study at Yale University found that delirium was far more widespread — and hazardous — than people realized, especially in intensive care units, where up to 85 percent of patients may be affected.
