This document discusses using a WhatsApp group to improve engagement of adolescents with type 1 diabetes. A group of 20 patients and 4 staff used WhatsApp to quickly share health information, provide support, and forge peer relationships between appointments. Qualitative feedback found patients felt they had improved access to information, support, and motivation to manage their diabetes. Quantitative results showed the average HbA1c level decreased from 9.7% to 9.0% after using WhatsApp. The study concludes that digital strategies like WhatsApp can be easily adopted into diabetes care to improve patient experience, access to information, and clinical outcomes.
