Abstract：Objective To analyze the predictive value of nutrition related clinical easy-to-use indicators for death risk of elderly patients with severe pneumonia.Methods Clinical records of 97 elderly patients with severe pneumonia in Affiliated Hospital of Chengdu University were retrospectively analyzed from July 2012 to June 2015;the patients were divided into dead group(n =38) and survival group (n =59) according to the outcomes.Related indicators including lymphocyte ratio,hemoglobin,total protein,albumin,prealbumin,serum creatinine and cholesterol were collected;values of these indicators for predicting death risk of patients were analyzed by the receiver operating characteristic curve.Results Area under curve of hemoglobin in predicting death risk was 0.660;the sensitivity was 0.568 and the specificity was 0.769.Area under curve of total protein in predicting death risk was 0.718;the sensitivity was 0.514 aud the specificity was 0.808 (both P ＜ 0.05).Combined detection of all indicators showed a high predictive value;area under curve was 0.782;the sensitivity was 0.808 and the specificity was 0.676 (P ＜ 0.05).Conclusion Hemoglobin and total protein have good values in predicting death risk of elderly patients with severe pneumonia;combined detection of multiple indicators can improve the predictive value.
