Rates of diabetes in youth are rising and more than 1 million children have diabetes. School nurses are central to a school-aged child's diabetes care and they must make important moment-to-moment decisions requiring understanding of and comfort with diabetes care and technology. The rapid changes in diabetes care and technology make ongoing education essential, yet access to up-to-date and practical education is limited for many school nurses. Integrating needs data and stakeholders' input, this group developed Diabetes in School Health (DiSH) to address this gap. We adapted a well-established, innovative, and easily-accessible telementoring educational model, Project ECHO, to create a collaborative learning community. In the first year, 9 diabetes experts and >150 school nurses joined live DiSH sessions. DiSH has been well-received by the school community and next steps include expansion of DiSH to other states and study of impact of DiSH on health disparities.
