Developing and Evaluating a WeChat-Based Applet Fluid Intake Reminder on Enhancing Fluid Adherence in Postoperative...

Area of Science:

• Digital Health
• Urology
• Preventive Medicine

Background:

• Urinary calculi (UC) affect 1%-13% globally, with high recurrence rates and significant healthcare costs.
• Poor adherence to fluid intake is a major barrier in UC prevention due to forgetfulness and limited education.
• Existing mobile health interventions for UC lack medical oversight and validation.

Purpose of the Study:

• To develop and evaluate a WeChat applet (WAFIR) for improving hydration behavior and reducing stone recurrence in postoperative UC patients.
• To assess the effectiveness of a digital therapeutic intervention in enhancing fluid adherence.
• To optimize postoperative management for urolithiasis patients.

Main Methods:

• An open-label, randomized controlled trial with 148 participants allocated 1:1 to an intervention or control group.
• The intervention group used the WeChat-Based Applet Fluid Intake Reminder (WAFIR) for personalized reminders and education.
• Outcomes, including fluid adherence and quality of life, were measured at baseline and 1- and 3-month follow-ups.

Main Results:

• The WAFIR applet was developed and finalized in February 2025.
• Recruitment and data collection occurred from March to September 2025, with analysis completed in December 2025.
• Findings are planned for dissemination in 2026.

Conclusions:

• The study evaluates a nurse-led, evidence-based digital therapeutic intervention (WAFIR) for postoperative urolithiasis patients.
• WAFIR aims to improve fluid intake, reduce UC recurrence, and enhance quality of life.
• The research seeks to provide empirical evidence for digital therapeutics in urology care.
