Purpose: Cardiac rehabilitation of patients with acute coronary syndrome has been reported to lower the morbidity and mortality due to coronary artery disease, but the participation rate in cardiac rehabilitation is still low due to various causes. It has been recently reported that home monitoring of cardiac rehabilitation by using wearable devices can increase participation rate of cardiac rehabilitation and patient satisfaction and compliance. A pilot study was conducted for development of home monitoring service for cardiac rehabilitation patients and user satisfaction evaluation.
Methods: Cardiac rehabilitation patients in the low-risk group and in ages of 40-65 years who can use smartphones among cardiac rehabilitation patients in the Department of Rehabilitation Medicine at Chungbuk National University Hospital were recruited for the study. During the clinical study, a pilot study was conducted for 2 months per subject with 2 subjects each in 2019 and 2020, for a total of 4 participants. Participants were instructed to perform cardiac rehabilitation exercise after wearing wearable devices provided at home, and submit the measurement data files after exercise. Participants were provided with feedbacks and recommendations on their cardiac rehabilitation performance every two weeks. After participating in the study for 2 months, a user satisfaction questionnaire on the home monitoring service for cardiac rehabilitation was conducted for the study participants.
Results: All four participants in the study completed the user satisfaction questionnaire. Regarding cardiac rehabilitation monitoring, the number of exercise for cardiac rehabilitation during participation in the clinical study averaged 4.5 times per week, increasing from 3.5 times per week before participation. To the questionnaire about whether participation in the clinical study was helpful in motivating exercise for cardiac rehabilitation, all participants answered that it was helpful. Regarding how much the information obtained through the feedback provided are satisfactory, 75% of the participants answered that they were satisfied, but 25% of the respondents answered that they were not satisfied because the ECG sensor used in the study was not as accurate as other products. Regarding if they were willing to use home monitoring service for cardiac rehabilitation if the service were provided by medical purposes, all participants answered that they will. Regarding the satisfaction of cardiac rehabilitation monitoring equipment, only 25% of the respondents were satisfied with the quality of the wearable device equipment used, indicating that the measurement ability of the monitoring equipment during exercise needs improvement, especially the wearable ECG device.
Conclusion: According to the user satisfaction survey, participants' satisfaction with cardiac rehabilitation monitoring was high, while the satisfaction for the equipment for monitoring equipment was low. Future research needs to be performed by expanding the number of participants for statistically significant analysis, and it is also necessary to use improved ECG device that can measure ECG and heart rate accurately during cardiac rehabilitation. Based on this study, the findings were used to identify the patients' needs for home monitoring service for cardiac rehabilitation and what to improve the monitoring services which include improved measurement ability of a wearable ECG device during exercise, although this study was a pilot study conducted with a small number of participants. These findings could contribute to the development of home monitoring service for cardiac rehabilitation patients in the future.
