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.
