Abstract

BACKGROUND
The purpose of this study is to investigate the incidence and associated factors of postoperative delirium in elderly patients with hip fracture.
METHODS
We interviewed 90 patients with hip fracture with the aim of identifying underlying diseases and laboratory data. Cognitive function was measured with Mini Mental Status Exam-K (MMSE-K) before surgery.
RESULTS
Delirium developed in 20 patients (22.2%). History of dementia (p=0.041) and mean score of MMSE-K (p<0.001) were significantly related to the incidence of delirium. An MMSE-K score less than 20 was an independent risk factor for postoperative delirium in patients with hip fracture.
CONCLUSION
Cognitive impairment was a risk factor of postoperative delirium. MMSE-K is expected to be a simple indicator for predicting postoperative delirium in older patients with hip fracture.
