WeChat-Based Digital Therapy to Improve Fluid Intake in Kidney Stone Patients: Study Protocol

The study outcomes will be reported to adhere to the guidelines outlined in the Consolidated Standards of Reporting Trials (CONSORT) 2010 statements. Reporting measures of central tendency (mean, median) and dispersion (standard deviation, range) for continuous variables, as well as frequencies and percentages for categorical variables. Statistical tests such as a t-test and chi-square test will be employed for continuous and categorical variables within two groups. The principal analysis will compare the fluid intake volume between the intervention and control groups using the t-test. Secondary outcomes such as The Wisconsin Stone Quality of Life Questionnaire (WISQOL), Patient Health Questionnaire-9 Items (PHQ-9), International Physical Activity Questionnaire (IPAQ-SF ) and The Electronic Health Literacy Scale (eHEALS) will use repeated measures of Analysis of Variance (ANOVA) since they are measured over time and between two groups. If necessary, subgroup analyses will be conducted to explore whether the effect of the intervention varies across different demographic or clinical subgroups. Intention-to-treat (ITT) analysis will be used to assess the impact of the treatment and its generalizability. A significance level of p \< 0.05 will be utilized to determine statistical significance, and all data analysis procedures will be conducted using the SPSS (Statistical Product and Service Solutions) 26.0 software package.The researcher is granted access to the complete trial dataset, with a contractual agreement established with the statistician to manage the data confidentially in accordance with the research protocol.
