In this cohort of 225 patients undergoing CABG or valve surgery, they were assessed with a mini-mental status exam (MMSE) and Confusion Assessment Method (CAM) preoperatively, daily from postoperative day 2 to discharge, and at 1, 6, and 12 months. Almost half (46%) developed delirium. At 6 months, the proportion of those that had not returned to baseline MMSE was significantly higher in those with delirium compared to those without (40% vs 24). Delirium prevention may improve long term cognitive function after cardiac surgery (abstract)
