Elderly patients awaiting lung resection surgery often have poor physical function, which puts them at a high risk of postoperative pulmonary complications. The aim of this study was to investigate the impact of preoperative physical performance on postoperative pulmonary complications in patients awaiting lung resection surgery. In this prospective multicenter cohort study, the characteristics of patients and postoperative pulmonary complications were compared between subjects with low (<10) and high (≥10) Short Physical Performance Battery (SPPB) scores. Postoperative pulmonary complications were defined as over grade II in Clavien-Dindo classification system. We estimated the effects of physical performance on postoperative pulmonary complications using multivariable hierarchical logistic regression. The postoperative pulmonary complications were compared between 331 patients in the high and 33 patients in the low SPPB group. Patients in the low SPPB score group had a significantly higher rate of postoperative pulmonary complications (p < 0.001). Low SPPB score was associated with a higher risk of postoperative pulmonary complications (odds ratio, 8.80; p < 0.001). The SPPB is a clinically useful evaluation tool to assess surgical patients’ physical performance. The low physical performance indicated by the SPPB may be predictive of postoperative pulmonary complications after lung resection surgery.

等待肺切除手术的老年患者通常身体机能较差，这使他们面临术后肺部并发症的高风险。本研究的目的是调查术前身体机能对等待肺切除手术患者术后肺部并发症的影响。在这项前瞻性多中心队列研究中，比较了低 (<10) 和高 (≥10) 短体能电池 (SPPB) 评分的受试者的患者特征和术后肺部并发症。在 Clavien-Dindo 分类系统中，术后肺部并发症被定义为 II 级以上。我们使用多变量分层逻辑回归评估了身体表现对术后肺部并发症的影响。比较高SPPB组331例和低SPPB组33例术后肺部并发症。低 SPPB 评分组的患者术后肺部并发症发生率显着较高（p < 0.001）。低 SPPB 评分与术后肺部并发症的风险较高相关（比值比，8.80；p < 0.001）。SPPB 是一种临床上有用的评估工具，用于评估手术患者的身体机能。SPPB 显示的低身体机能可能预示着肺切除手术后的术后肺部并发症。低 SPPB 评分与术后肺部并发症的风险较高相关（比值比，8.80；p < 0.001）。SPPB 是一种临床上有用的评估工具，用于评估手术患者的身体机能。SPPB 显示的低身体机能可能预示着肺切除手术后的术后肺部并发症。低 SPPB 评分与术后肺部并发症的风险较高相关（比值比，8.80；p < 0.001）。SPPB 是一种临床上有用的评估工具，用于评估手术患者的身体机能。SPPB 显示的低身体机能可能预示着肺切除手术后的术后肺部并发症。
