abstract: 'Purpose: The breast imaging modalities of mammography, ultrasound, and
|
|
|
|
|
|
|
|
|
|
MRI are widely used for screening, diagnosis, treatment, and
|
|
|
|
|
|
|
|
|
|
surveillance of breast cancer. Geographic access to breast imaging
|
|
|
|
|
|
|
|
|
|
services in various modalities is not known at a national level overall
|
|
|
|
|
|
|
|
|
|
or for population subgroups.
|
|
|
|
|
|
|
|
|
|
Methods: A retrospective study of 2004-2008 Medicare claims data was
|
|
|
|
|
|
|
|
|
|
conducted to identify ZIP codes in which breast imaging occurred, and
|
|
|
|
|
|
|
|
|
|
data were mapped. Estimated travel times were made for each modality for
|
|
|
|
|
|
|
|
|
|
215,798 census block groups in the contiguous United States. Using
|
|
|
|
|
|
|
|
|
|
Census 2010 data, travel times were characterized by sociodemographic
|
|
|
|
|
|
|
|
|
|
factors for 92,788,909 women aged >= 30 years, overall, and by subgroups
|
|
|
|
|
|
|
|
|
|
of age, race/ethnicity, rurality, education, and median income.
|
|
|
|
|
|
|
|
|
|
Results: Overall, 85\% of women had travel times of <= 20 minutes to
|
|
|
|
|
|
|
|
|
|
nearest mammography or ultrasound services, and 70\% had travel times of
|
|
|
|
|
|
|
|
|
|
<= 20 minutes for MRI with little variation by age. Native American
|
|
|
|
|
|
|
|
|
|
women had median travel times 2-3 times longer for all 3 modalities,
|
|
|
|
|
|
|
|
|
|
compared to women of other racial/ethnic groups. For rural women, median
|
|
|
|
|
|
|
|
|
|
travel times to breast imaging service''s were 4-8-fold longer than they
|
|
|
|
|
|
|
|
|
|
were for urban women. Black and Asian women had the shortest median
|
|
|
|
|
|
|
|
|
|
travel times to services for all 3 modalities.
|
|
|
|
|
|
|
|
|
|
Conclusions: Travel times to mammography and ultrasound breast imaging
|
|
|
|
|
|
|
|
|
|
facilities are short for most women, but for breast MRI, travel times
|
|
|
|
|
|
|
|
|
|
are notably longer. Native American and rural women are disadvantaged in
|
|
|
|
|
|
|
|
|
|
geographic access based on travel times to breast imaging services. This
|
|
|
|
|
|
|
|
|
|
work informs potential interventions to reduce inequities in access and
|
|
|
|
|
|
|
|
|
|
utilization.'
