Much research has focused on potential causes of delirium however the sequelae of delirium have not been well investigated. The objective of this study was to investigate the relationship between delirium and sepsis post coronary artery bypass grafting CABG and to determine if delirium is a predictor of sepsis. Methods Peri-operative data were collected prospectively on all patients. Subjects were identified as having agitated delirium if they experienced a short-term mental disturbance marked by confusion illusions and cerebral excitement. Patient characteristics were compared between those who became delirious and those who did not. The primary outcome of interest was post-operative sepsis. The association of delirium with sepsis was assessed by logistic regression adjusting for differences in age acuity and co-morbidities. Results Among 14 301 patients 981 became delirious and 227 developed sepsis post-operatively. Rates of delirium increased over the years of the study from to P . A total of 70 patients of the 227 with sepsis were delirious. In of patients delirium preceded the development of overt sepsis by at least 48 hours. Multivariate analysis identified several factors associated with sepsis receiver operating characteristic ROC delirium odds ratio OR 95 confidence interval CI to emergent surgery OR CI to age OR CI to pre-operative length of stay LOS more than seven days OR CI to pre-operative renal insufficiency OR CI to and complex coronary disease OR CI to . .
