The Effect of a Mobile Application on Enhancing Pulmonary Rehabilitation After Lung Cancer Surgery

September 17, 2024 updated by: Kun-Ling Tsai, National Cheng Kung University

The Effectiveness of a Mobile Lung Rehabilitation System on Patient Satisfaction and Lung Function After Lung Cancer Surgery

The goal of this clinical trial is to investigate the effect of a mobile application intervention on postoperative lung rehabilitation. The main purposes of this study are:

  1. To understand the effectiveness of the pulmonary rehabilitation mobile application in improving lung function.
  2. To assess the feasibility of the pulmonary rehabilitation mobile application in post-surgery rehabilitation care.

Researchers will compare the intervention group (using the pulmonary rehabilitation mobile application) to the usual care group to determine if the mobile application is effective in lung surgery rehabilitation.

Participants will join the study immediately after providing informed consent and will continue for up to 7 weeks post-surgery. Participants will be randomly allocated to either the intervention group or the control group. Both groups will receive regular pulmonary rehabilitation during their hospital stay (1 day before surgery and 2 to 3 days after surgery). Researchers will guide participants in the intervention group to use the mobile application for pulmonary rehabilitation exercises throughout the study period. Participants in the usual care group will receive health education and an exercise guide before discharge. Participants will undergo three study assessments: at baseline (within 1 week after enrollment), post-surgery (week 5), and at follow-up (week 8).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: application inttervention group
The experimental group will receive standard postoperative care, including chest rehabilitation, a mobile application for remote self-training every day after surgery, and an interactive healthcare web platform for health education.
Behavioral: RehabLung mobile application
Participants in the intervention group will receive in-person pulmonary rehabilitation during their surgical admission and access to a mobile pulmonary rehabilitation application for self-training. This program begins one month before surgery and continues for seven weeks after surgery. The application is designed to encourage participants to engage in pulmonary rehabilitation exercises from preoperative preparation through postoperative care.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Exercise capacity-oxygen consumption
Time Frame: Baseline, post-surgery assessment at week 5, follow-up assessment at week 8
Cardiorespiratory fitness is evaluated by a cardiopulmonary exercise test using a cycle ergometer. Participants will be encouraged to perform a cycle ergometer stress test to assess their cardiopulmonary function. During the test, the workload will gradually increase by 10 watts per minute until the participant reaches peak exercise capacity. Throughout the exercise test, participants will be carefully monitored for echocardiography and heart rate, and will wear a mask to analyze ventilatory outcomes using a computed gas analysis system. Peak oxygen consumption (VO2 peak) will be measured during the exercise test, and values for the difference and change in percent predicted (peak oxygen uptake [mL/kg/min], VO2 peak difference [mL/kg/min], VO2 peak change [%], and [% predicted]) will be obtained from gas analysis. The predicted values will be referenced from the system based on race, age, height, biological sex, and weight.
Baseline, post-surgery assessment at week 5, follow-up assessment at week 8
Exercise capacity-workload
Time Frame: Baseline, post-surgery assessment at week 5, follow-up assessment at week 8

Throughout the exercise test, participants will be carefully monitored for echocardiography and heart rate, and will wear a mask to analyze ventilatory outcomes using a computed gas analysis system.

The workload achieved during exercise test will be recored by peak work rate (watts), and peak work rate (%pred.) The predicted workload will be referenced from the system based on race, age, height, biological sex, and weight.

Anaerobic threshold (AT) (mL/kg/min) is defined as a nonlinear increase in CO2 production, which will be analyze during gas analysis in an incremental exercise test.
Baseline, post-surgery assessment at week 5, follow-up assessment at week 8
Pulmoanry function
Time Frame: Baseline, post-surgery assessment at week 5, follow-up assessment at week 8
The pulmonary function test, assessed by spirometry, is performed to evaluate lung volumes over time and ventilatory capacity. Participants will be guided by experienced therapists to take a maximal inspiration, then exhale with maximal effort for as long and as fast as possible. Measurements include forced vital capacity (FVC [L, % predicted]), forced expiratory volume in one second (FEV1 [L, % predicted]), and the ratio of the two volumes (FEV1/FVC [% predicted]). The predicted values will be referenced from large population studies of healthy adults, matched by race, age, height, biological sex, and weight.

Quality of life - EORTC QLQ-C30
Time Frame: Baseline, post-surgery assessment at week 5, follow-up assessment at week 8
Quality of life specific to lung cancer patients is assessed using the EORTC QLQ-C30 (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30). This questionnaire evaluates various aspects of quality of life, including physical, role, cognitive, emotional, and social functioning, as well as cancer-related symptoms and overall health status. Scores range from 0 to 100 across the 30 items. A higher score on the global scale indicates a better quality of life.

The compliance score will be calculated based on participants' responses to the scaled questions and will be expressed as a total compliance score, with higher scores indicating better compliance. The measurement tool will be a customized compliance scale designed for this study, allowing participants to indicate the extent to which they followed the exercise instructions as prescribed.
