Abstract
Background: The Prognostic Nutritional Index (PNI) as a prognostic tool for the postoperative outcomes in patients undergoing thoracic surgery due to an infectious etiology remains unexplored.
Objective: To evaluate the PNI as predictor of poor postoperative outcomes in patients undergoing surgery for a thoracic infection.
Material and methods: A retrospective analysis in patients undergoing VATS during January 2019 to December 2023, including 61 patients. We performed a ROC curve analysis to identify the optimal PNI cut-off value to classify the patients into groups: A high (HR) and low-risk (LR) group. Chi-square, Fisher exact, and Mann-Whitney tests were used to compare them. A multivariate analysis with Cox regression was also performed.
Results: The optimal PNI cut-off value was 28.69, with AUC 0.860 (p = 0.001), sensitivity 88.9%, specificity 78.8%. 42 patients were low-risk, while 19 high-risk. There was a significant difference in 30-day mortality between groups (HR 42% vs LR 2%, p < 0.001) as well as in 30-day major complications (HR 68% vs LR 16%, p < 0.001). A multivariate analysis revealed that PNI-based risk group was an independent predictor of mortality (p = 0.008) and major complications (p < 0.001).
Conclusions: The PNI is a valid predictor of poor postoperative outcomes in patients undergoing VATS for a thoracic infection.
背景:预后营养指数(PNI)作为感染性胸外科手术患者术后预后的预测工具仍未被探索。目的:评价PNI作为胸部感染手术患者术后不良预后的预测指标。材料与方法:对2019年1月至2023年12月接受VATS治疗的61例患者进行回顾性分析。我们进行了ROC曲线分析,以确定最佳PNI截断值,将患者分为高(HR)和低(LR)组。使用卡方检验、Fisher精确检验和Mann-Whitney检验对它们进行比较。采用Cox回归进行多变量分析。结果:最佳PNI临界值为28.69,AUC为0.860 (p = 0.001),敏感性为88.9%,特异性为78.8%。低危42例,高危19例。两组间30天死亡率(HR 42% vs LR 2%, p < 0.001)以及30天主要并发症(HR 68% vs LR 16%, p < 0.001)均有显著差异。多因素分析显示,pni风险组是死亡率(p = 0.008)和主要并发症(p < 0.001)的独立预测因子。结论:PNI是胸部感染患者行VATS术后不良预后的有效预测指标。
