BACKGROUND: Structural factors limiting access to surgical care require elucidation. We hypothesize transportation time to hospitals with surgical capacity disproportionately burdens minority populations.
METHODS: We identified hospitals with surgical capacity within a 20-mile radius of our city center. Using geocoding, we estimated travel times from each census tract to the nearest facility by car or public bus.
RESULTS: For 143 tracts within the county, drive time was 13 ± 4 min and bus time was 33 ± 15 min. Only 41.2% of the population had a facility within 30 min by bus; access was further diminished for those with minority race/ethnicity and/or no insurance. Bus time was associated with percent minority population in a census tract: for each 10% increase in minority population there was a 4.3-min increase in bus time (p < 0.001) when controlling for socioeconomic status and other characteristics.
CONCLUSIONS: Geographic information systems analysis has potential to identify communities with disproportionate burden to access surgical services.
