Abstract
BACKGROUND
Delirium is associated with increased morbidity and mortality. The factors associated with post-lung transplant delirium and its impact on outcomes are under characterized.

METHODS
The medical records of 163 consecutive adult lung transplant recipients were reviewed for delirium within 5 days (early-onset) and 30 hospital days (ever-onset) post-transplantation. A multivariable logistic regression model assessed factors associated with delirium. Multivariable negative binomial regression and Cox proportional hazards models assessed the association of delirium with ventilator duration, intensive care unit (ICU) length of stay (LOS), hospital LOS and one-year mortality.

RESULTS
Thirty six % developed early-onset and 44% – ever-onset delirium. Obesity (OR 6.35, 95% CI 1.61-24.98) and bolused benzodiazepines within the first post-operative day (OR 2.28, 95% CI 1.07-4.89) were associated with early-onset delirium. Early-onset delirium was associated with longer adjusted mechanical ventilation duration (p=0.001), ICU LOS (p<0.001), and hospital LOS (p=0.005). Ever-onset delirium was associated with longer ICU (p<0.001) and hospital LOS (p<0.001). After adjusting for clinical variables, delirium was not significantly associated with one-year mortality (early-onset HR 1.65, 95% CI 0.67-4.03; ever-onset HR 1.70, 95% CI 0.63-4.55). CONCLUSIONS
Delirium is common after lung transplant surgery and associated with increased hospital resources. This article is protected by copyright. All rights reserved.
