Maps
Service Areas for Joint Commission Primary
Stroke Centers
The following maps have been created to show access to IV tPA
treatment for the whole region, and for each state in the
northwest region. The ground and air transportation times to
Joint Commission Primary Stroke Centers (PSC) are shown, where
"H" symbolizes each PSC, and population data are based on the
2000 Census tract. Please note the following assumptions that
were made:
- Treatment capable time (180 minutes) = recognition time
(20-30 minutes) + transport time (60-90 minutes) + treatment
time (60 minutes of ED time)
- Transport time includes dispatch, scene evaluation, etc.
- Total treatment capable population = population within
driving distance + population within air transport distance
- The maps show travel time to primary stroke centers
only. Other hospitals can and do give
IV tPA for
stroke. Contact your hospital for more information.
