Risk factors of post-anaesthesia care unit delirium in patients undergoing non-cardiac surgery in Singapore.

In this first local study, the incidence of PACU delirium was 3.8%, with the incidence increasing to 6.2% in those older than 65 years old. Understanding these risk factors will form the basis for which protocols can be established to optimise resource management and prevent long term morbidities and mortality of PACU delirium.
