Summary
Brief summary (as posted)
This is a prospective observational study that evaluates whether the Shuttle Walking Test (SWT) can predict postoperative symptoms, particularly dyspnea, in patients with chronic respiratory diseases undergoing lung resection. Currently, tools such as DLCO or cardiopulmonary exercise testing (CPET) are used to assess surgical risk and exercise capacity before lung surgery. However, these tests are not always accessible due to equipment limitations or long waiting times. The SWT is a simpler, safer, and more cost-effective alternative that has been recently recognized as a new medical technology in Korea for evaluating exercise capacity. In this study, patients with chronic lung diseases (such as COPD, ILD, or bronchiectasis) who are scheduled to undergo lung resection will perform the SWT before surgery. Their symptoms and quality of life will be assessed through questionnaires before and three months after the surgery. The goal is to determine whether SWT results can help predict postoperative dyspnea and provide useful information for preoperative risk stratification.

- measure
- Change in Dyspnea Score From Baseline to 3 Months After Lung Resection
- timeFrame
- From baseline (preoperative) to 3 months postoperatively
- description
- Dyspnea will be assessed using a validated scale (e.g., POSPNEA or MRC). The difference in scores between preoperative baseline and 3 months after surgery will be analyzed.

- Predictive Value of Shuttle Walking Test for Postoperative Dyspnea
- timeFrame
- Preoperative to 3 months postoperative
- description
- The correlation between preoperative SWT results (ISWT distance, endurance time) and postoperative dyspnea score at 3 months will be evaluated using regression analysis.
