Dr. Alexander K. Smith Co-publishes Commentary in JAMA Internal Medicine
Postoperative delirium is common in older adults, yet some of its long-term consequences remain debated.
While its association with adverse outcomes is well established—including longer hospital stays, functional decline, institutionalization, and mortality—a more challenging question is whether delirium itself contributes to later cognitive decline or if it mainly identifies patients who already have frailty, have a health record that is medically complex, and are likely to become ill again.
A study co-published by Dr. Alexander K. Smith, titled "Cognition After Postoperative Delirium—The Confusion Has Cleared but All Is Not Well” provides data that advances this debate.
The study was published in the journal JAMA Internal Medicine.
