A Mobile Application Based Dietary Self Management Intervention in Chinese Chronic Kidney Disease Patients

Not Applicable
Conditions
Chronic Renal Disease
Interventions
Behavioral: Mobile Application for Dietary Management
Registration Number
NCT04940819
Lead Sponsor
Peking Union Medical College Hospital
Brief Summary

This is a multi-center randomized controlled study. This study aims to investigate the acceptability and efficacy of a newly developed mobile application in the dietary management of chronic kidney disease (CKD) patients.

Detailed Description

The prevalence of CKD has reached 10.8% in China. Increasing in prevalence of other non-communicable disease such as hypertension, diabetes and obesity is contributing to this rise in CKD and end-stage renal disease prevalence. Diet is a strong modifiable factor in these diseases. Dietary control is also an integral part in CKD disease self management. However, the complexity in the dietary management of CKD makes it hard for patients to adequately self manage. With the development of smart phone, many mobile applications have been developed to suit the need of patients with chronic diseases. But there has been a scarce of randomized trial to support the feasibility, acceptability and efficacy of these mobile applications.

Our study aims to employ a newly developed dietary logging and monitoring application in the primary care setting of CKD patients to test its acceptability and efficacy in disease control.

The application is developed by a multidisciplinary team in a tertiary care center. The main features include searching and logging foods, receiving realtime feedback on key nutrient intake levels and facilitating patient-care giving communication.

We plan to enroll 14 tertiary hospitals and 42 secondary hospitals in 7 geographical regions in China aiming to reach participants in resource poor areas. Participants will be randomized with 1 to 1 ratio to either receiving mobile application dietary intervention or usual dietary consultation. The planned intervention period is 3 months. We will monitor biochemical parameters relating to dietary control and evaluate patient-centered outcomes concerning CKD self management and control.

Primary Outcome Measures
NameTimeMethod
Change in Proteinuria3 months

spot urine before and after intervention period

Diet Quality3 months

Calculated by Chinese Healthy Eating Index

Change in Disease Related Quality of life3 months

Measured by Kidney Disease Quality of Life 36-Short Form questionnaire

change in estimated Glomerular Filtration Rate (eGFR)3 months

blood draw (fasting) before and after intervention period

Dietary Intake3 months

Dietary intake of calorie, protein, sodium, potassium and phosphate evaluated by three-day diet records (3DDR)

Blood Pressure3 months

Measure BP in office visits after the intervention period. Changes in antihypertensive medication requirements (total number, dose, class) will be collected from participants and verified with hospital records.

Change in Self-Efficacy for Managing Chronic Disease Scale3 months

Score of Self-Efficacy for Managing Chronic Disease Scale (6 items, each measured on a 1-10 likert scale, higher score indicate better self-efficacy) before and after intervention period

Change in Perceived Medical Condition Self-Management Scale (PMCSMS)3 months

Measured by Perceived Medical Condition Self-Management Scale (8-item CKD-specific version of the PMCSMS, each item is scored on a 1-5 likert scale, with higher score indicating better self management on item 3/4/5/8 and lower score indicating better self management on item 1/2/6/7) before and after intervention

Secondary Outcome Measures
NameTimeMethod
Acceptability of the Application3 months

Measured by user acceptability survey and semistructured interviews conducted in participants and nephrologists

Urine Sodium/potassium Ratio3 months

Measured by spot urine at baseline and after intervention

Kidney Nutrition Knowledge, Attitude and Practice3 months

Measured by self developed questionnaire about knowledge, attitude and practice in kidney disease specified diet

Adoption3 months

Measured by percentage of complete dietary log in days will be counted (\>1200kcal deemed as complete log)

Blood Chemistry (Potassium, Bicarbonate, Phosphate)3 months

blood draw (fasting) before and after intervention period

Salt Taste Threshold3 months

Salt taste threshold measured using salt-impregnated test strips before and after the intervention period

Adherence3 months

Total number of diet diary logged by participants over complete study period (more than 60% logged is deemed good adherence)

Change in the score of Generalized Anxiety Disorder Scale3 months

Measured by Generalized Anxiety Disorder Scale (a 7-item self-report scale. Items are rated on a 4-point Likert-scale with 0 = not at all to 3 = nearly every day ) before and after intervention

Change in the score of Hospital Anxiety and Depression Scale3 months

Measured by Hospital Anxiety and Depression Scale (14 items each rated on a 0-3 score, with higher score indicating worse anxiety or depression symptoms) before and after intervention
