Findings

The darkest-shaded areas are neighborhoods that had access to stroke centers within 30 minutes. The lighter- shaded areas had access within 60 minutes, while the very light-shaded areas had access within 90 minutes. Most of the areas that had long travels time to stroke centers were neighborhoods in the rural areas.

Purpose

The map was generated to investigate and identify neighborhood disparities in travel time (geographic accessibility) to emergency stroke care. It shows that important disparities in geographic accessibility to stroke care exist in East Tennessee Appalachian Region. This may have significant implications for health outcomes related to stroke.
