Detailed Description
Idiopathic nephrotic syndrome (NS) is one of the most common chronic kidney diseases in children, with a prevalence of approximately 16 cases per 100,000 children. NS is characterized by heavy urinary losses of protein leading to hypoalbuminemia, edema, and hyperlipidemia. Children are treated with high-dose corticosteroids on presentation, and >80% respond to treatment with resolution of proteinuria and symptoms. However, 80-90% of the children initially sensitive to corticosteroids will experience disease relapse, with more than half relapsing frequently or becoming dependent on corticosteroids to maintain remission. During a relapse, patients can suffer from anasarca, acute kidney injury, serious infections, or thromboembolic events.
Management of children with NS entails long-term outpatient surveillance and treatment. Home care includes the important standard-of-care task of urine monitoring to follow the relapsing-remitting nature of the disease. New proteinuria signals disease relapse before the development of overt symptoms such as edema. Thus, patients are instructed to alert their providers to the occurrence of proteinuria in a timely manner so that corticosteroids can be initiated or adjusted to treat each relapse and prevent acute disease complications. It is also important for the patients to track urine protein for resolution so that corticosteroids can be stopped or reduced to minimize steroid toxicity.
Not unlike other chronic, relapsing-remitting pediatric disorders, self-management is difficult for NS patients and their caregivers. Mobile health (mHealth) is a promising, rapidly growing field in disease management. In NS, there are numerous aspects of self-management that may be facilitated by a mobile app. First, the visual analysis of a urine test strip is subject to human error, including reading the wrong reagent block and erroneous assessments of color. This can be improved through using a smartphone's camera and computer to read and analyze test strip results. Second, caregivers must remember to check their child's urine, recall results, and understand what the results mean: the demands are taxing in that disease relapse is defined as urine protein ≥2+ for 3 consecutive days and remission is defined as negative/trace urine protein for 3 consecutive days. Apps, with their inherent interactivity, can provide reminders for urine testing, capture the results, and analyze trends to detect disease relapse/remission. Apps can alert a caregiver to seek medical attention and directly transmit test results to providers. Lastly, apps can provide medication reminders for NS patients, who are on highly complex medication regimens.
UrApp was iteratively developed by an expert panel of two pediatric nephrologists and three research engineers with expertise in human-computer interaction. App features were devised by the clinicians to support elements of chronic care management according to the Chronic Care Model and tasks that are challenging for caregivers. This study will include 60 caregivers of children with newly diagnosed nephrotic syndrome. Participants will be randomized 1:1 to UrApp or standard of care and followed for 1 year. In addition to the study outcome measures, user feedback will be collected via survey, interview, and by stakeholder meetings to inform app refinement.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: UrApp
Participants randomized to this study arm will use the UrApp mobile application for one year, in addition to receiving the standard of care.
|
Participants will be provided a folder of educational material on NS, including general information on symptoms, treatments, and possible complications; healthy diet for children taking corticosteroids; and low sodium diet.
Site research staff will demonstrate how to check urine for protein with test strips, and educate patients on the definitions of disease relapse and remission.
Urine test strips and urine protein logs will be provided to ensure that each participant can check their urine daily for protein.
Participants will be instructed to check their urine daily for protein and call their provider within 1 business day for relapses and remissions.
Caregivers/parents will download UrApp at the baseline visit.
UrApp contains instructional videos to guide users.
The telephone number of the patient's provider will be entered into UrApp and participants will be able to call their providers directly through UrApp.
The email address of the Emory study staff will also be entered.
UrApp will automatically e-mail test results to the research staff when elected by the users.
Participants will be asked by study staff, and reminded by the app, to call their providers and send urine testing results to the study staff whenever there is a relapse or remission.
When the study staff receives alerts of a relapse/remission via UrApp, the information will be communicated to the treating physician within 1 business day.

|
Change in Urine Monitoring Adherence
Time Frame: Baseline, Month 6, Month 12
|
Adherence with urine protein monitoring is defined as checking, on average, at least 2 times a week in the month preceding the assessment.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Self-efficacy
Time Frame: Baseline, Month 6, Month 12
|
Self-efficacy for managing nephrotic syndrome will be assessed with a 3-item instrument adapted from the Chronic Disease Self-Efficacy Scales.
Responses are given on a 10-point scale where 0 = not confident at all and 10 = totally confident.
Total scores range from 0 to 30 with higher scores indicating increased self-efficacy.
|
Baseline, Month 6, Month 12
|
Change in Patient-Reported Outcomes Measurement Information System - Pediatric Quality of Life Inventory (PedsQL) Score
Time Frame: Baseline, Month 6, Month 12
|
The 23-item PedsQL was developed as part of the NIH Roadmap Initiative to create universal measures for patient-reported outcomes, and contains questions in the domains of social-peer, depression, anxiety, mobility, and function.
Responses are given on a 5-point scale where 0 = never and 4 = almost always.
Items are reverse scored and linearly transformed to a scale of 0 to 100, where higher total mean scores indicate a better quality of life.
|
Baseline, Month 6, Month 12
|
Change in Delayed Relapse Detection
Time Frame: Month 6, Month 12
|
The number of delayed relapses detected will be compared between study arms.
Patient medical charts will be reviewed for occurrence and frequency of delayed relapse reporting which is defined as a relapse that was not reported to the treating physician until clinical manifestations or complications occurred and/or only discovered during planned or unplanned visits or hospitalizations.
|
Month 6, Month 12
|
Change in Hospitalizations
Time Frame: Month 6, Month 12
|
The number of hospitalizations will be compared between study arms.
Medical records will be reviewed for the primary reason for admission and NS disease complications, such as bacterial peritonitis, septicemia, shock, blood clot(s), acute kidney injury, and seizures from hyponatremia or hypertension.
