An analysis of patients who had undergone esopha­gectomy found that postoperative delirium appears to affect about one-half of this population. More than one-third of study patients required psychoactive med­ications for their symptoms of delirium. Postoperative delirium was significantly associated with longer hos­pital or ICU stay, postoperative complications, and longer time under postoperative mechanical ventila­tion, among other factors.
