User profile and engagement with a digital health application for urolithiasis management: A descriptive study of the...

Urolithiasis is a prevalent urological condition that requires continuous monitoring and management to prevent recurrence. The myLit-Control® App is a digital health tool designed to support self-management by tracking urinary pH, water intake, and medication adherence. This study aimed to describe the demographic and clinical characteristics of myLit-Control® App users in Spain, analyze their engagement patterns, and evaluate adherence to health goals.

This retrospective observational study included users who downloaded the app between May 2022 and June 2024. Data on demographics, urinary pH tracking, water intake, and medication adherence were extracted and analyzed to explore correlations, group comparisons, and identify factors influencing adherence and outcomes.

The study included 699 users, with a median age of 50 years (IQR 40-59) and 57.1% male. A total of 217 users (31.0%) were taking urolithiasis-specific treatment. Urine pH monitoring was used by 52.9% of participants, with a rate of 53% (± 37) within target pH levels. Water intake tracking was the most frequently used feature, yet adherence to hydration goals remained low (15±30%). A negative correlation was observed between age and treatment adherence (r=-0.456, p<0.001).

The myLit-Control® App facilitates urinary pH monitoring and medication adherence, supporting self-management in urolithiasis patients. However, engagement with key features, particularly water intake tracking, remains suboptimal. Future research should explore long-term outcomes and strategies to enhance patient adherence, ensuring effective integration of mHealth tools in routine clinical practice.
