In a study conducted in Ethiopian hospitals, 41% of patients developed postoperative delirium after surgery. Patients aged 75 or older were 11 times more likely to experience delirium, and those with severe functional impairment or premedication with benzodiazepine also had higher odds. Other risk factors included ASA-PS IV status, intraoperative blood loss over 1000 ml, and intraoperative ketamine use. Delirium prolonged both post-anesthesia care unit and hospital stays.
