Association of wearable device-based perioperative physical activity with recovery outcomes in patients undergoing lung cancer surgery: a systematic review and meta-analysis protocol.

INTRODUCTION

Lung cancer surgery is a cornerstone of curative treatment for resectable disease, but postoperative recovery is often prolonged and may be complicated by impaired pulmonary function, reduced physical activity, symptom burden and delayed functional restoration. Wearable devices may support perioperative physical activity through objective monitoring and activity promotion; however, existing evidence remains fragmented and has not been synthesised in a focused review. This protocol describes a systematic review and meta-analysis to evaluate the association of wearable device-based perioperative physical activity with recovery outcomes in patients undergoing lung cancer surgery.

METHODS AND ANALYSIS: We will include randomised controlled trials, non-randomised interventional studies and prospective or retrospective cohort studies involving adults undergoing surgery for suspected or confirmed primary lung cancer. Eligible studies must examine wearable device-based perioperative physical activity during the preoperative period, postoperative period or both. The primary outcomes will be postoperative pulmonary complications, length of hospital stay and physical function or exercise capacity. Secondary outcomes will include overall postoperative complications, pulmonary function, symptom burden, health-related quality of life, chest tube duration, readmission and postoperative mortality. We will search PubMed, EMBASE, Web of Science, CINAHL and the Cochrane Library from inception to the final search date, supplemented by reference screening, forward citation tracking, grey literature and trial registry searches. Two reviewers will independently perform study selection, data extraction and risk-of-bias assessment. Where appropriate, meta-analysis will be performed using random-effects models; otherwise, findings will be synthesised narratively.

ETHICS AND DISSEMINATION: Ethical approval is not required because this review will use data from published studies and publicly accessible sources only and will not involve individual participants or identifiable personal data. The findings will be disseminated through publication in a peer-reviewed journal and presentation at relevant academic or professional conferences.
