The authors studied the occurrence of admission hyponatremia and its association with selected patient and hospitalization characteristics and in-hospital mortality in a geriatric patient cohort (n = 4,123). Prevalence of admission hyponatremia was 3.5% and higher among women (4.6% vs 2.6%). In-hospital mortality was 16% for patients with admission hyponatremia versus 8.0% for patients without admission, hyponatremia. Adjusting for patient and hospitalization characteristics with a logistic regression analysis, admission hyponatremia was a significant independent predictor of mortality (RR = 1.95). Admission hyponatremia is associated with poor prognosis in the elderly hospitalized population.
作者对老年患者队列（n = 4123）中入院时低钠血症的发生率及其与选定的患者和住院特征以及院内死亡率的关联进行了研究。入院时低钠血症的患病率为3.5%，女性中的患病率更高（4.6%对2.6%）。入院时患有低钠血症的患者院内死亡率为16%，而未患入院时低钠血症的患者为8.0%。通过逻辑回归分析对患者和住院特征进行校正后，入院时低钠血症是死亡率的显著独立预测因素（相对危险度 = 1.95）。入院时低钠血症与老年住院人群的不良预后相关。
