Changes in Emergency Department Access Between 2001 and 2005 Among General and Vulnerable Populations

Vol. XIII, No. 6
November 2010

As part of a HCFO funded study, Yu-Chu Shen, Ph.D., of the Naval Postgraduate School Graduate School of Business, and Renee Hsia, M.D., M.Sc., of the University of California, San Francisco, examined how geographic access to EDs, measured by driving time, changed from 2001 to 2005. The researchers further explored whether vulnerable populations were more susceptible to these changes. In addition, the researchers assessed whether other market- and area-level factors are associated with declined geographic access to the ED.
