Objectives:

To assess whether preoperative levels of physical activity predict the incidence of post-operative complications following anatomical lung resection.

Methods:

Levels of physical activity (daily steps) were measured for 15 consecutive days using pedometers in 90 consecutive patients (prior to admission). Outcomes measured were cardiac and respiratory complications, length of stay, and 30-day re-admission rate.

Results:

A total of 78 patients’ datasets were analysed (12 patients were excluded due to non-compliance). Based on steps performed they were divided into quartiles; 1 (low physical activity) to 4 (high physical activity). There were no significant differences in age, smoking history, COPD, BMI, percentage predicted FEV1 and KCO and cardiovascular risk factors between the groups. There were significantly fewer total complications in quartiles 3 and 4 (high physical activity) compared to quartiles 1 and 2 (low physical activity) (8 vs 22; P = .01). There was a trend (P > .05) towards shorter hospital length of stay in quartiles 3 and 4 (median values of 4 and 5 days, respectively) compared to quartiles 1 and 2 (6 days for both groups).

Conclusions:

Preoperative physical activity can help to predict postoperative outcome and can be used to stratify risk of postoperative complications and to monitor impact of preoperative interventions, ultimately improving short term outcomes.

术前体力活动可预测肺癌切除术后的手术结果

目标：

评估术前体力活动水平是否能预测解剖肺切除术后并发症的发生率。

方法：

在 90 名连续患者（入院前）中使用计步器连续 15 天测量身体活动水平（每日步数）。测量的结果包括心脏和呼吸系统并发症、住院时间和 30 天再入院率。

结果：

总共分析了 78 名患者的数据集（12 名患者因不依从而被排除在外）。根据执行的步骤，它们被分为四分位数；1（低体力活动）到 4（高体力活动）。各组之间在年龄、吸烟史、COPD、BMI、预测的 FEV1 和 KCO 百分比以及心血管危险因素方面没有显着差异。与四分位数 1 和 2（低体力活动）相比，四分位数 3 和 4（高体力活动）的总并发症显着减少（8 对 22；P = .01）。与第 1 和第 2 分位数（两组均为 6 天）相比，第 3 和第 4 分位数（分别为 4 天和 5 天的中位数）有缩短住院时间的趋势 ( P > .05)。

结论：

术前体力活动有助于预测术后结果，可用于对术后并发症的风险进行分层，并监测术前干预的影响，最终改善短期结果。
