The feasibility of smartphone-based application on cardiac rehabilitation for Chinese patients with percutaneous coronary intervention in Macau: a qualitative evaluation

Abstract

Background To improve cardiovascular risk factors modification and effects of cardiac rehabilitation (CR), electronic applications on CR are suggested in the literature for patients after percutaneous coronary intervention (PCI). Methods A sequential qualitative study, embedded in a quantitative experimental trial for mHealth application on CR (mCR) study evaluation, was conducted to understand the usability and satisfaction of mCR study. Purposive sampling were used until achieving data saturation. Individually semi-structured interviews were conducted. The textual narration from interview transcriptions were analysed by content analysis. Results Ten participants were interviewed for qualitative evaluation. Findings presented the perceptive and experience of the mCR app users. Results were captured by four themes: 1. feasibility of mCR app, including practicality, acceptability and convenience, and barriers to use; 2. benefits from mCR app, explaining the effectiveness of mCR study; 3. advocator for better hospital care, disclosing an extension of healthcare and promoting patient-healthcarer relationship; and 4. recommendation for mCR app improvement. Conclusion Findings provided insights for cardiac healthcare providers to understand the feasibility of mHealth application on phase II CR in Macau. The mCR app facilitated CR engagement which contributed to health and well-being by promoting CHD and CR knowledge, and cardiac healthy lifestyle modification.
