Development and user acceptability testing of healthy heart mobile application - a tool for cardiovascular risk...

Cardiovascular disease (CVD) remains the primary cause of mortality in individuals with type 2 diabetes mellitus. Digital health has quickly emerged as a technology with the ability to bridge the gap in cardiovascular disease self-management and revolutionize the way healthcare has traditionally been delivered. However, there is little data on the application of mobile technologies for cardiovascular risk reduction among diabetic patients. The current study has been constructed with this in mind.

A framework for the development of a healthy heart mobile application for CVD risk stratification and risk management among Type 2 diabetes mellitus patients was finalized after consultation with diabetologists, nutritionists, and scientists. The mobile app has three user cases: Patient login, doctor login, and admin login. A questionnaire was designed and the feedback of patients and Physicians was taken regarding the design, presentation, content, and user-friendliness of the app based on responses obtained on the questionnaire.

The Android version of the healthy heart mobile mobile app was developed for CVD risk stratification and risk management among type 2 diabetes mellitus patients. The dashboard of the mobile app displayed the CVD risk score and category (mild, moderate, high, or very high CVD risk; which was colored coded), health tracker to monitor medication adherence, lipid profile, diabetes control, CVD risk profile and compliance with the WHO recommendations regarding diet, physical activity and addictions, User acceptability and experience were tested for the developed healthy heart mobile app among patients and physicians. The majority of the respondents graded the design, presentation, content, and user-friendliness of the app as either excellent or good.

The mobile app for self-management and CVD risk reduction among diabetic patients was successfully developed. The paper and mobile-based CVD risk calculation and stratification were found to be a match for all the participants. The app was updated based on suggestions from the pilot study and was well-accepted by both patients and physicians.
