Background: Video-assisted thoracoscopic (VATS) lobectomy can affect patients’ pulmonary function and quality of life significantly. No optimal protocol combining patient-reported outcome-based symptom management and post-discharge rehabilitation programme has yet been established. This study aimed to assess the efficacy of a novel smartphone app designed for home-based symptom management and rehabilitation. Methods: The app was developed based on three modules: a symptom reporting system with alerts, aerobic and respiratory training exercises, and educational material. Four core symptoms were selected based on a questionnaire survey of 201 patients and three rounds of Delphi voting by 30 experts. We screened 265 patients and randomly assigned 136 equally to the app group and usual care group. The primary outcome was pulmonary function recovery at 30 days postoperatively. Secondary outcomes included symptom burden and interference with daily living (both rated using the MD Anderson Symptom Inventory for Lung Cancer), aerobic exercise intensity, emergency department visits, app-related safety, and satisfaction with the app. Findings: Of the 136 participants, 56.6% were women and their mean age was 61 years. The pulmonary function recovery ratio 1 month after surgery in the app group was significantly higher than that in the usual care group (79.32% vs. 75.73%; P =0.040). The app group also recorded significantly lower symptom burden and interference with daily living scores and higher aerobic exercise intensity after surgery than the usual care group. Thirty-two alerts were triggered in the app group. The highest pulmonary function recovery ratio and aerobic exercise intensity were recorded in those patients who triggered alerts in both groups. Interpretation: Using a smartphone app is an effective approach to accelerate home-based rehabilitation after VATS lobectomy. The symptom alert mechanism of this app could optimise recovery outcomes, possibly driven by patients’ increased self-awareness.
