Abstract: Objective To analyze the factors influencing 2-year survival rate in elderly patients with femoral neck fracture treated conservatively. Methods From January 1,2015 to January 1,2018,63 patients with femoral neck fracture treated conservatively in the Sixth Medical Center of Chinese PLA General Hospital were included.There were 24 males and 39 females,with the mean age of (85.54±5.61) years and (84.13±5.38) years respectively.Hypertension was found in 40 cases (63.5%),diabetes in 24 cases (38.1%),coronary heart disease (CHD) in 42 cases (66.7%),lung infection in 34 cases (54.0%),chronic obstructive pulmonary disease (COPD) in 27 cases (42.9%),heart failure in 11 cases (17.5%),hypoproteinemia in 24 cases (38.1%),dementia in 16 cases (25.4%),renal failure in 7 cases (11.1%),non-stay in bed time less than 2 hour per day in 28 cases (44.4%).All patients were followed up for 2 years after injury to observe the survival.Univariate analysis and multivariate Cox regression analysis were applied to explore independent risk factors related to death. Results After 2 years of follow-up,43 of the 63 patients survived and 20 died,with a mortality rate of 31.7%.Univariate analysis suggested that pulmonary infection,hypoproteinemia,and non-stay in bed time less than 2 hours per day were associated with 2-year survival rate.Further multivariate analysis showed that pulmonary infection (HR,7.145;95% CI1.631,31.308) and non-stay in bed time less than 2 hours per day (HR,5.564;95% CI1.825,16.962) were independent risk factors for 2-year survival rate after injury. Conclusion Elderly patients with femoral neck fracture treated conservatively should spend less time lying in bed and pay more attention to the prevention of pulmonary infection,and active cough and enhanced sputum should be suggested to help to prolong life.
