Clinical Trial Summary

The purpose of this study is to create a smartphone app that delivers the educational content of the current Intermountain MAWDS* program and allows patients to enter and track their MAWDS data within the app; and to determine if a broad-scale project can be conducted within the limits of currently available technology. Information from this study will be used to design a larger study that is powered to assess the association between data obtained via a MAWDS app and heart failure outcomes.

(*MAWDS- Medications, Activity, Weight, Diet, Symptoms)

Clinical Trial Description

The Intermountain Heart Institute will collaborate with Savvysherpa Inc to develop a sensor-based digital platform based on MAWDS. (MAWDS is Intermountain's acronym that stands for Medications, Activity, Weight, Diet, Symptoms; used across Intermountain Healthcare to represent the most important concepts and skills to teach heart failure patients) This will be used to deliver simple, home-based interventions via an app on the subject's iPhone. The app will be programmed to send notifications to the subject to enter their MAWDS data and perform a 6-minute walk test at specific time points during the study. Written informed consent will be obtained from each subject prior to participation. A study team member will register eligible subjects as well as assist them with the iPhone and HealthKit set-up and train them on the app usage. Protocol-required information will be obtained from subject's medical records (collected as part of their usual medical care). Subjects will be asked to enter data into the MAWDS iPhone app at specified intervals for a period of 3 months. The data, with the date and time it was entered, will be posted to a study-specific database. Periodically, the MAWDS app will query activity data from HealthKit and post that to the same database. Scheduled notifications will appear in the iPhone's Notification Center, reminding the subject to use the app. To assess subject engagement, the app will collect and store standard usage statistics provided by the iOS (e.g., number of times and duration the app is used per day, number of data entries, etc). The subjects' electronic medical records will be reviewed for a period of 3 months following enrollment, focused on healthcare utilization (e.g., hospital readmissions, mortality, changes in Intermountain HF (heart failure) Risk Score, etc). All information will be made part of the study-specific database. Follow-up phone calls will be done, as needed, within the first 2 weeks after enrollment to remind subjects to activate the app, ensure that the subjects are using the app appropriately, and address any issues noted on monitoring the data collected via the app. Subjects will have no other research-related clinic visits or in-person follow-up evaluations, other than the visit for obtaining informed consent, registration and setting up of the app, and follow-up telephone calls as needed. Upon completion of the study, the app on the subject's iPhone will be disabled and Savvysherpa will disconnect the "backend" data capture. Data will no longer be collected from the subject and his/her medical records will no longer be accessed. ;
