User-Centered Design and Validation of mHealth App for Providing Vital Assistance and Emergency Healthcare Support in Bangladesh

Bangladesh is experiencing an increase in demand for easy-to-use digital healthcare solutions. In response to this demand, "SushthoJibon" was introduced as a prototype of a mobile health (mHealth) application which is a comprehensive solution and designed to provide vital aid during emergencies as well. Based on the principles of user-centered design, this app has many other features such as Knowledge Hub, Report Station, Medicine Cabinet with Reminders, Poribar Porijon (Family Care), Nearby Healthcare Services and Appointments, Emergency Response, and Exercise Tracking. The app was well received in terms of usability measured using the mHealth App Usability Questionnaire (MAUQ) and the User Experience Questionnaire (UEQ), where ease of use and user experience were emphasized by the users’ feedback. Subsequent changes were made based on the findings, which allowed "SushthoJibon" to fully meet the needs of its users.
