Postoperative delirium (POD) and postoperative cognitive decline (POCD) are common after surgeries in the elderly, especially after cardiothoracic surgery. These conditions are associated with adverse short- and long-term outcomes. Multiple conditions in the perioperative period have been proposed as risk factors of POD and POCD. Incidences vary across institutions due to differences in screening and diagnostic tools.
This is a prospective observational study to identify the incidences and risk factors of postoperative delirium and postoperative cognitive decline after elderly patients undergoing cardiac surgical procedures which require cardiopulmonary bypass and postoperative intensive care unit (ICU) admission. Patients will be screen for POD and POCD with various psychological tests in the postoperative period and after hospital discharge. Perioperative data and outcomes will be used to identify risk factors of both conditions.
