Association between WeChat-based remote care guidance and diabetic foot ulcer healing: a retrospective cohort study
Summary: PeerJ retrospective cohort (2021–2022, follow-up to 2024; n=131 DFU patients): WeChat-based remote guidance (education, image assessment, MDT consultations) as adjunct to standard care significantly improved healing (88.1% vs. 63.9%; HR=2.27), faster times, QoL, and satisfaction. Stronger effects in moderate ulcers (Wagner 2–3) and interventional cases; supports mHealth for self-management in resource-limited settings.
Key Highlights:
- Healing: 88.1% intervention vs. 63.9% control (P=0.001).
- Subgroups: High HR in Wagner 2–3 (up to 34.2) and post-procedure.
- Benefits: Improved QoL/satisfaction; high engagement via text/video/interactive.
- Relevance: Effective remote tool for chronic DFU management/healing acceleration.
