Title: CONFUCIUS Study : Impact of a Multifaceted Program to Prevent Postoperative Delirium in the Elderly
Brief Summary: Postoperative delirium is common in the elderly and is associated with a significant increase in mortality, complications, length of hospital stay and admission in long care facility. Several interventions have proved their effectiveness to prevent it but their combination within a multifaceted intervention needs to be assessed using rigorous methodology based on randomized study design. CONFUCIUS trial aims to measure the impact of a multifaceted program on the prevention of postoperative delirium in elderly.
