Supporting Self-Management of Healthy Behaviors in Chronic Kidney Disease

The pilot cross-over study aims to examine the feasibility of a smartphone-based self-management supportive intervention, Supporting Self-Management of Healthy Behaviors (SMART-HABITS) in patients with chronic kidney disease (CKD) and hypertension. SMART-HABITS is a web-based application accessible on any device that has Internet access and utilizes a mobile health research platform (Way to Health) that links to wearable sensor smartphone applications such as FitBit and Omron Connect, to provide reminders, tailored feedback, and provide access to educational resources, and to community resources. The cross-over design is used to test preferences of using text message or a smartphone app to communicate blood pressure readings.

The pilot study aims to examine the feasibility, as measured by adoption, adherence, and acceptance, of a smartphone-based self-management supportive intervention, Supporting Self-Management of Healthy Behaviors (SMART-HABITS) in patients with chronic kidney disease (CKD) and hypertension. SMART-HABITS is a web-based application accessible on any device that has Internet access and utilizes the mobile health research platform to provide the components of the intervention: a) text message reminders (Arm 1), b) text message tailored feedback (Arm 1 and 2), c) positive affirmation text messages (Arms 1 and 2), d) access to educational resources, community resources, CKD patient forums (Arms 1 and 2), e) option to select a accountability partner to share reminders and feedback (Arms 1 and 2). SMART-HABITS encompasses multiple behavior change techniques and is centered on the Health Belief Model and the Social Cognitive Theory. SMART-HABITS will deliver reminder text messages to a participant's smartphone to perform blood pressure self-monitoring in one arm and encourage an increase in walking activity both arms. The Omron Connect app will deliver the reminder notifications to check blood pressure and will deliver the BP readings to research platform (in the non-texting arm). After blood pressure measurements and daily step counts are remotely transmitted from the smartphone to mobile health research platform server, tailored feedback will be provided via text message). Additionally, intermittent positive affirmation messages will also be sent to participants to encourage engagement in the behaviors. Within the SMART-HABITS web-based application, there will be a participant portal that will provide access to links to community resources, educational links about CKD, and a display of adherence to behaviors and data transmission. At the beginning and end of the study, questionnaires will be completed to assess patient-reported outcomes, which will serve as secondary endpoints.
