Key result
MMSE-K score below 20 is linked to postoperative delirium in elderly hip fracture patients.
Why the study?
Cognitive impairment as a risk factor for postoperative delirium in elderly patients with hip fracture was investigated to identify predictive indicators.
Observational (n=90)
p-value: p=<0.001
Cognitive impairment, specifically an MMSE-K score less than 20, is a significant predictor of postoperative delirium in elderly patients undergoing hip fracture surgery.
Warrants consideration in preoperative assessment of elderly hip fracture patients; leaves open whether screening improves delirium outcomes.
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.

Sohn et al. (2010) conducted an observational in Hip fracture (n=90). MMSE-K score less than 20 vs. MMSE-K score 20 or greater was evaluated on Postoperative delirium (p=<0.001). An MMSE-K score less than 20 was an independent risk factor for postoperative delirium in elderly patients with hip fracture (overall incidence 22.2%).
