Application of Digital Health Interventions in Home Self-Management of Patients Undergoing Transcatheter Aortic Valve Replacement: A Scoping Review and Future Perspectives.
Hailian Chen, Shuang Zou, Linlin Zheng
PMID 42717415WHAT IT FOUND
Digital tools for post-TAVR home care show promise in improving exercise capacity and reducing readmissions.
However, evidence is weak for hard outcomes like mortality, and adoption is hindered by poor digital literacy, connectivity issues, and lack of insurance coverage. Nurse-led screening and simplified tools are key.
Key findings
01Digital health interventions may reduce readmissions and improve exercise capacity, but evidence for hard clinical endpoints like mortality is weak.
02Patient barriers such as low digital literacy, poor internet access, and physical discomfort significantly limit the adoption of these technologies.
03Nurses are advised to screen for digital literacy before discharge and use simplified, age-appropriate teaching methods to support patient self-management.

What it does not show
No formal quality assessment of included studies was conducted, limiting conclusions about efficacy. Most studies were small, single-center, and had short follow-up periods. There was significant heterogeneity in outcome measures, preventing meta-analysis. Studies often excluded patients without smartphones or internet, creating selection bias and limiting generalizability to vulnerable populations. Evidence for hard clinical endpoints (mortality, stroke) is lacking.
Declared interests
Funded by the National Science Fund for Distinguished Young Scholars of China and the Zhejiang Province Medical and Health Science and Technology Planning Project. The authors declared no conflicts of interest.
The easy way to misread this
Do not assume these digital interventions are proven to save lives or prevent heart attacks. The positive findings are largely based on surrogate outcomes like exercise distance and readmission rates in small, non-randomized studies. The evidence for hard clinical endpoints is weak, and the lack of quality assessment means these results should be viewed as preliminary.
