目的

探讨影响老年脓毒症患者短期预后的影响因素,并评估其预测患者28 d预后的价值。

方法

选取2018年1月至2020年1月上海市普陀区中心医院收治的112例老年脓毒症患者的临床资料。根据患者28 d转归情况分为死亡组和存活组。采用Cox比例风险回归模型分析影响患者预后的因素,受试者工作特征(ROC)曲线评估各指标对老年脓毒症患者28 d病死率的预测价值。

结果

存活组52例,死亡组60例。Cox比例回归风险分析结果显示,年龄、乳酸水平、尿酸碱度和前白蛋白水平是影响老年脓毒症患者短期预后的独立影响因素(RR=1.035、1.270、0.332、0.000,P<0.05或0.01)。ROC曲线分析结果显示,各单项指标中,乳酸的预测价值最高,曲线下面积(AUC)为0.836,敏感度和特异度分别为90%和81%;乳酸联合其他各项指标联合预测的AUC为0.907,敏感度和特异度分别为85%和88%。

结论

年龄、乳酸、尿酸碱度、前白蛋白是老年脓毒症患者死亡的独立影响因素,联合4项指标可以更准确地预测患者28 d预后情况。

Objective

To explore the influencing factors for short-term prognosis of elderly patients with sepsis, and to evaluate their value in predicting 28 day prognosis.

Methods

Clinical data of 112 elderly patients with sepsis admitted to the Emergency Department of Shanghai Putuo District Central Hospital from January 2018 to January 2020 were retrospectively analyzed. The patients were divided into the death group and survival group according to the 28-day outcome. Cox proportional hazard regression model was used to analyze the factors influencing the prognosis of patients, and receiver operating characteristic (ROC) curve was used to evaluate the predictive value of the influencing factors on the 28 day outcome of patients.

Results

There were 52 patients in the survival group and 60 in the death group. Cox proportional hazard regression analysis showed that age, lactic acid level, urine pH value and prealbumin level were independent influencing factors for short-term prognosis of elderly patients with sepsis (RR=1.035, 1.270, 0.332, 0.000; P < 0.05 or P < 0.01). ROC curve analysis showed that lactic acid level had the highest predictive value compared with age, urine pH value and prealbumin level, with the area under the curve (AUC) of 0.836, sensitivity and specificity of 90% and 81%, respectively; while when predicted using lactic acid level combined with age, urine pH value and prealbumin level, the AUC increased to 0.907, and the sensitivity and specificity were 85% and 88%, respectively.

Conclusion

Age, lactic acid level, urine pH value and prealbumin level are independent influencing factors for short-term prognosis of elderly patients with sepsis, and combined used of these indicators can accurately predict the 28 day prognosis of patients.
