Dulce Wireless Tijuana: Empowering Communities to Promote Diabetes Care and Prevention Through 3G Technologies

The current epidemic of diabetes in northern Mexico and around the world highlights the urgent need for innovative, efficient, technology-supported interventions to prevent and monitor the disease. Dulce Wireless Tijuana is a bi-national, multi-sector study that examines how the chronic care model together with 3G wireless Internet access can be used in diabetes management to improve patient care for marginalized communities. The main site of this project is the Family Medicine Unit #27 of the Instituto Mexicano del Seguro Social, (IMSS UMF 27) located in Tijuana, Mexico.



  • The Dulce Wireless Tijuana Study works by consolidating and centralizing patient information and extending diabetes education to communities via 3G wireless technologies and community classes. Patients, promotores (community health workers), nurses and doctors access the system via mobile devices such as cellphones, netbooks and laptops.
  • The Dulce Wireless Tijuana Study utilizes 3G wireless technologies to enhance a chronic care model based on the Project Dulce approach, where nurses work closely with an interdisciplinary group of physicians at a clinic and outreach workers in the community.
  • The clinical protocol was approved by the IMSS and research intervention began in January 2012.
  • A total of 300 patients have participated in the study. All patients are randomly assigned to one of three groups: approximately 100 patients participate in the control group, 98 participate in the clinical intervention, and 102 patients participate in the clinical and 3G technology intervention, which allows for the following functionality:
    • Electronic Diabetes Management Health Record: The health care workers that are part of the study can locate and receive confidential access to a patient’s medical information in the study’s database via a computer or laptop anytime, anywhere using 3G wireless technologies.
    • Manage Patient Reminders: Health care workers in the study can manage health data and patient reminders using a customized web application. The system sends automatic reminders to patients via SMS.
    • MyGlucoHealth Glucose Meter: Providers upload blood glucose readings to the project’s network to monitor technology group patient’s control and intervene if necessary.
    • Access to Diabetes Care Content: Patients use 3G cellphones to access videos and health education on key diabetes self-management topics.
    • Interactive Surveys: A Brew™ platform application on the mobile phones provides a questionnaire to patients to monitor how they are managing their diabetes. Patients’ responses are sent through their 3G mobile phones, making them instantly available in the database for the health care providers to review.
    • Notification and Alert System: Promotores, nurses and doctors participating in the study can send voice and text messages to patients. Alerts are sent to clinical staff when patients report significantly out of range indicator levels or when the system identifies lack of adherence to appointments, tests or classes. These alerts appear in the health care workers’ database for their immediate review and follow-up.
