This choropleth map displays state-level cardiovascular disease mortality rates per 100,000 people by census tract for the state of Hawaii, ages 18–65 years, for the years 2007–2013. Many of the communities with the highest rates of mortality—from 234.3 to 1830.2 per 100,000—are located more than 45 minutes from the nearest designated stroke center. There is an inset map of the island of O‘ahu that shows a magnified view of the drive time analysis, location of the designated stroke centers, and highest areas of cardiovascular disease burden.
Cardiovascular disease mortality rates and 45-minute drive times to stroke center hospitals in Hawaii

Data sources

Several census tracts in the highest quartile of cardiovascular disease mortality rates are located on islands (Hawaii [Big Island], Moloka‘i, and Lana‘i) with no access to a stroke center. Even on O‘ahu, with three designated stroke centers, there are several census tracts with high mortality rates that fall outside the 45-minute drive time range.

This map will be useful to identify areas that are lacking resources to properly treat persons who have had a stroke.

Cardiovascular disease deaths were classified into quartiles. ArcGIS Network Analyst was used to determine a 45-minute drive time to a stroke center and was symbolized with cross-hatching.
