The adoption of CRR, enabled by data-driven risk prediction and management tools that use community data resources, has the potential to help create a future in which fire departments systematically prevent EMS calls “upstream” and better address the root causes of EMS calls, thus preventing “rekindles.” In this lecture, we will draw on our in-process project, which involves four large, geographically distributed fire departments who provide EMS through both transport and non-transport models, to discuss trends in medical aid calls that shape priorities for CRR in EMS, including social determinants of health. We will describe how methods from the discipline of design– such as design research and human-centered design processes– can be used to help meet these challenges and develop “human-centered” CRR tools and systems for both the present and the future of CRR for EMS Finally, we will discuss lessons learned from our academic-fire service collaboration.
