Trauma centers are not evenly distributed across the United States,
which may leave some patients without timely access to care. Branas and colleagues
reviewed national data on trauma centers, helipads, and block group population
to estimate the proportion of US residents living within 45 and 60 minutes
of a trauma center. They found that more than 80% of US residents have access
to a level I or II trauma center within an hour; however, 46.7 million, primarily
in rural areas, reside at even greater distance from trauma care.
