DEAR DOCTOR K: My elderly mother has a number of health conditions. Over the past year, she has ended up in the hospital four times. The last two times, she became delirious. Is there anything we can do to prevent delirium if she has to have another hospital stay?
DEAR READER: Unfortunately, delirium is common among older patients in hospitals, particularly after surgery or during a stay in an intensive care unit (ICU). One-third to two-thirds of elderly hospital patients develop delirium.
