Method: A retrospective analysis was conducted to analyze the basic information and laboratory test data of elderly sepsis patients (aged ≥ 65 years) admitted to the Emergency ICU of the East Campus of Qingdao Hospital of Rehabilitation University from January 2021 to July 2024. According to the hospitalization outcome, they were divided into a survival group and a death group, and their general information and laboratory data were compared between the two groups. Single-factor and multi-factor logistic regression analyses were used to assess the relationship between PNI and the death of elderly patients with sepsis. Receiver operating characteristic (ROC) and calculate area under the curve (AUC) are drawn to evaluate the predictive performance of PNI. Result: A total of 133 patients were included, with 92 in the survival group and 41 in the death group, resulting in a mortality rate of 30.8%. The survival group had significantly higher levels of albumin, PNI, total protein, and platelets than the death group, with statistical significance (P < 0.05). The SOFA, APACHE II scores, and urea nitrogen levels in the death group were significantly higher than those in the survival group, and the differences were statistically significant (P < 0.05). Univariate logistic regression analysis showed that PNI, SOFA score, APACHE II score, total protein, albumin, and lactate were related factors leading to death in elderly sepsis patients. According to the results of multiple logistic regression analysis, PNI is an independent risk factor for in-hospital mortality in sepsis patients. The ROC curve analysis results showed that the area under the curve (AUC) for predicting in-hospital mortality in sepsis patients using PNI, lactate, SOFA, and APACHE II scores was 0.625, 0.604, 0.644, and 0.649, respectively. The area under the four joint prediction curves is 0.697, with a sensitivity of 63.4% and a specificity of 78.3%. Conclusion: Low PNI is an independent risk factor for the prognosis of elderly sepsis patients, with good sensitivity and specificity. When combined with lactate, SOFA, and APACHE II scores for prediction, PNI can improve the specificity of predicting mortality in elderly sepsis patients.展开更多
