This report details the important challenges that experts in public health informatics face in communicating with professionals who work in—or who influence—the broader field of public health. These challenges—such as the fact that non-experts do not see public health informatics as a science, or even as a field of practice or expertise—impede the full incorporation of informatics into public health practice, and lead to a lack of appreciation of the potential of informatics to improve population health outcomes. The report concludes with initial reframing recommendations that can be used to address these communications challenges and suggestions for future research on developing an evidence-based Core Story of Public Health Informatics.
