Clinical Trial Summary

A 12-week, prospective, multicenter, open-label pilot randomized controlled trial (RCT) will be carried out to determine the feasibility, acceptability and potential clinical efficacy of a newly developed mobile diet app among CKD populations at different stages in Malaysia. Participants will be randomly assigned into either (i) intervention group (mobile diet app) or (ii) control group (dietary counseling using conventional pamphlet).


Description:

General Objective: To evaluate a newly developed mobile diet app in enhancing dietary adherence for patients with chronic kidney disease. Specific Objectives: 1. To validate the newly developed mobile diet app for patient with chronic kidney disease. 2. To determine the feasibility and acceptability of this newly developed mobile diet app among patients with chronic kidney disease. 3. To evaluate the preliminary efficacy of the newly developed mobile diet app in enhancing dietary adherence in patients with chronic kidney disease

Study Design


Intervention

Other:
Counseling
Subjects in the both arms will receive individualized dietetic counseling as the standard dietetic care in Malaysia
Renal Diet App
Individualized dietetic counseling aided with a newly developed renal diet app for educative purpose and aiding tool to enhance the dietary adherence among CKD patients. Training on the use of the app will be provided to the subjects prior to the commencement of the intervention. Subjects will be trained on the use of the home screen, icons, feedback screens, the process of entering dietary and fluid intake data and selecting portion sizes. Subjects are considered as competent users when they could correctly record the foods and drinks with correct portion size eaten in the past 24 hours and successfully save the data.
Printed Nutrition Pamphlet
After the counseling session, a standardized renal nutrition pamphlet prepared by dietitians from Universiti Putra Malaysia and Hospital Serdang will be given for patient's educative purpose. Since the mobile application is intended for patient's education and self-monitoring (food diary) purposes, and thus, to ensure the comparability between intervention and control groups, the patients in control group will be trained to record their diet intakes manually using the recommended approach 3-day diet records. Nutritional feedback or advices on the diet records will be given to the participants during follow up sessions.

Outcome

Type Measure Description Time frame Safety issue
Primary Glomerular Filtration Rate (eGFR) Estimated glomerular filtration rate (eGFR) will be recorded in of mL/min/1.73m2. 3 months
Primary Serum Kidney Function Test Routine collected biochemical results from the patients' medical records:
- urea, sodium, chloride, potassium and creatinine will be measured in mmol/L
3 months
Primary Serum Hemoglobin A1C Test Routine collected biochemical results from the patients' medical records for HbA1C (%) 3 months
Primary Serum Blood Sugar Profile Routine collected biochemical results from the patients' medical records and blood sugar (mmol/L) also will be recorded if patient had done self-monitoring blood glucose at home 2 weeks
Primary Albuminuria Routine collected urine analysis to measure urine albumin (mg) if there is presence of albumin or protein 12 weeks
Primary Dietary History Three-day diet records (3DDR) : 2 days weekdays + 1 weekend / dialysis and non-dialysis day. Measured unit is in kilocalories (kcal)/day 6 weeks
Primary Dietary Adherence End Stage Renal Disease Adherence Questionnaire (ESRD-AQ):
- validated questionnaires which consists of 4 subscales pertaining dialysis, medication, dietary and fluid adherences. Patients will need to rate their fluid and dietary adherence on a numerical rating scale which composed of 0% (None of the time) to 100% (All of the time).
6 weeks
Secondary Feasibility of the app: interview The feasibility of the app will be measured by the app usage. Study participants will be interviewed for app usage in term of frequency (e.g. in average how many days of usage in a week) and extent of its usage (e.g. how much time has spent on the app in a day). The intervention (mobile diet app) is consider feasible if the subject used the app more than 50% of study duration which is 42 days (6 weeks). 12 weeks
Secondary Acceptability: User Acceptance test (UAT) Acceptability of the app will be measured using User Acceptance test (UAT). It consisted of 11 items and each item was rated on a 5-point Likert scale (1 = Strongly disagree, 3 = neutral, and 5 = Strongly agree). 12 weeks
Secondary Users Satisfaction: Likert scale The evaluation questionnaire included 7 items evaluated using a five-point Likert scale (1 = Strongly disagree, 3 = neutral, and 5 = Strongly agree) on the composition of the app, on the design and layout of the app, and overall satisfaction. 12 weeks
Secondary Health Behaviour A set of self-developed items will be used to assess the patient's perceptions of dietary adherence based on HBM constructs. Content validity have been done by 3 experts with the reported S-CVI/UA of 0.93. This part consisted of 28 items derived from available literatures, assessing different constructs of HBM 12 weeks
Secondary Nutrition Literacy A dialysis-specific nutrition-related health literacy has been developed based on health literacy theory model (Sørensen et al., 2012) by the researchers and validated among HD patients with the content validity measured by S-CVI/AVE of 0.96 and construct validity measured by average variance extract (AVE) of 0.589 as well as composite reliability of 0.877 (unpublished data). 12 weeks
Secondary Nutritional Status Anthropometry data will be collected by researchers at 2 time points, baseline (V0) and study end-point (V2). Malnutrition inflammation score (MIS) will be used to assess patient's nutritional status (Kalantar-Zadeh, Kopple, Block & Humphreys, 2001). 12 weeks
Secondary Dietary Knowledge The kidney disease-related dietary knowledge questionnaire was modified from (Durose et al., 2004) based on the Malaysian MNT Guidelines for CKD, (MDA, 2005) which was adopted from the K-DOQI guidelines (NKF 2000; NKF 2003). 12 weeks
