Mortality and risk factors for hip fractures in elderly patients within 30 days of surgery / 中华老年医学杂志

ABSTRACT

Objective:To investigate the mortality and related risk factors for hip fractures in elderly patients within 30 days of surgery.Methods:Clinical data of elderly hip fracture patients in our hospital from January 2012 to December 2016 were retrospectively analyzed.Based on whether they survived within 30 days of surgery, patients were divided into the death group and the survival group.Differences in age, gender, comorbidities, timing of operation and fixation mode between the two groups were compared.Univariate analysis was conducted to detect significant factors, and Logistic regression analysis were performed to identify independent risk factors for 30-day mortality after operation.Results:A total of 1350 elderly hip fracture patients were treated in our hospital, and 1004 cases met the inclusion criteria.Forty-three cases(4.28%)died within 30 days of operation.Univariate analysis showed that, compared with the survival group, the death group had a higher average age, a higher white blood cell count, lower hemoglobin and albumin levels, higher proportions of patients with arrhythmia, more pulmonary infections, higher cardiac insufficiency and more people with ≥4 comorbidities.Multivariate Logistic analysis showed that arrhythmia( OR=2.36, P=0.038), pulmonary infection( OR=2.50, P=0.020), cardiac insufficiency( OR=3.15, P=0.016), high white blood cell count( OR=1.14, P=0.006), and low albumin( OR=1.08, P=0.037)were independent risk factors for increased mortality within 30 days of operation. Conclusions:The 30-day mortality rate is high in elderly hip fracture patients.Arrhythmia, pulmonary infection, cardiac insufficiency, high white blood cell count, and low albumin level are independent risk factors for mortality in elderly hip fracture patients.
