Methods DSM-Ⅳ was adopted to diagnosis of perioperative delirium in the elderly with hip fracture, The data of 148 elderly patients with hip fracture were analyzed retrospectively and classified according to the clinical characteristics. The differences were analyzed statistically between the delirious group and the control group.

For the type of delirium, there were 15 cases with mania type, 4 cases with inhibitory type and 7 cases with mixed type. Compared with patients in control group, patients with perioperative delirium were older [(79.67±7.7) years old vs. (75.5±7.0)years old, t=2.668, P=0.008)]. Five cases who had previous delirium occurred perioperative delirium, and five patients who received external fixator showed no perioperative delirium.
