J Am Coll Nutr. 1991;10:383-393

Page 25: Mobile Health Technologies in Cardiovascular Disease

Focus Groups About Sodium Intake

• Patients say they struggle picking low sodium options in restaurants

• Patients think restaurants don’t serve low-sodium foods

• Patients have low confidence in picking low sodium foods at restaurants

• Patients cannot tell if a grocery store item is low in sodium

• Patients have low confidence estimating how much sodium they eat in a day

Health IT and sodium

• Intervention – a mobile application– Geofencing-based alerts at restaurants with low sodium

options– Scanning foods at grocery stores and providing lower sodium

options– Top 5 sodium containing foods

• Aim 1 – Develop the messages in focus groups• Aim 2 – Study the efficacy of the mobile application in HTN

Mortality:≈50% at 5 yearsEconomic costs:

Heart Failure

• Self-management is defined as an active cognitive process undertaken by the patient to manage their heart failure

• HF patients self-monitor weight, sodium, fluid intake and symptoms

• Patients interpret self-monitoring and perform self-management

• We developed a website application to determine if self-monitoring improved HF status

Page 33: Mobile Health Technologies in Cardiovascular Disease

Health IT and Heart Failure

• Prospective single-center pre/post study• Patients enrolled from the Advanced HF at the

FCVC• Self-monitoring was performed for 12 weeks• HF status was measured by:

– NYHA class, MLWHF, weight, exercise, walk distance, physical exam

Health IT and Heart Failure

• Developing a mobile application that incorporates many aspects of the website

• Adding into the application passive remote monitoring and motivational messages

• Creating a predictive model to identify pre-clinical markers of clinical worsening using wearable devices

Page 42: Mobile Health Technologies in Cardiovascular Disease

Conclusions

• Mobile technology offers a chance to collect data about patients in their environment and gives researchers access to data that has not been collected previously

• GPS and geofencing are promising technologies for contextual just-in-time interventions

• Wearable devices may offer a key into pre-clinical states in chronic disease management
