ABSTRACT
Objective:To investigate the prognosis of hip fracture in elderly patients with dementia.Methods:From January 2012 to December 2017, 91 dementia patients aged (82.7±6.6)y (21 males and 70 females) with hip fracture were enrolled in the study; 91 non-dementia patients matched by age, gender and fracture type were selected as controls. There were 54 cases of intertrochanteric fracture and 37 cases of femoral neck fracture. The length of hospital stay, mortality within 30 days and 1 year, walking ability and risk of reoperation were compared between the two groups. The effect of dementia on the mortality after surgery was analyzed by adjusting confounding factors through multivariate logistic regression analysis.Results:There was no significant difference in the length of hospital stay between dementia group and non-dementia group [(13.95±7.33) vs.(12.63±8.68)d, t=1.12, P=0.266]. The incidence rate of perioperative complications in dementia group was higher than that in non-dementia group [63.7%(58/91) vs. 23.1%(21/91), χ 2 = 44.59, P<0.001]. The incidence of delirium in dementia group was higher than that in non-dementia group [35.3%(42/91) vs.13.2%(12/91), χ 2 = 5.71, P=0.017]. The incidence of pulmonary infection in dementia group was higher than that in non-dementia group [11.0%(10/91) vs. 2.2%(2/91), χ 2= 11.989, P<0.001]. There was no significant difference in 30-day fatality rate [7.7%(7/91) vs. 1.1%(1/91), χ 2= 3.27, P=0.071] between two groups; while the 1-year fatality rate in dementia group was higher than that in non-dementia group [27.5%(25/91) vs. 14.3%(13/91), χ 2= 4.79, P=0.029]. After adjusting for the differences of confounding factors between the two groups, dementia was an independent risk factor for 1-year mortality after hip fracture surgery ( OR = 1.852, 95 %CI:1.048-3.043, P= 0.022). For walking ability of 1 year after operation, 22 (33.3%) patients in dementia group walked independently, 38 (57.6%) patients partially walked independently, 6 (9.1%) patients were in bed; while in non-dementia group, 45 (57.7%) patients walked independently, 27 (34.6%) patients partially walked independently, 6 (7.7%) patients were in bed; there was significant difference between the two groups (χ 2= 8.82, P=0.012). There was no significant difference in reoperation rate between two groups [6.6%(6/91) vs. 5.5%(5/91), χ2=0.10, P=0.756]. Conclusion:Compared to non-dementia patients, dementia patients with hip fracture have poorer prognosis, higher incidence of perioperative complications, pulmonary infection and delirium, higher risk of mortality 1 year after operation, and poorer ability of independent walking.
