Cao, S., Gentili, M.4, Griffin, P., Serban, N. (Submitted May 2016) Small-Area Estimation of Spatial Access to Pediatric Preventive Dental Care and Its Implications for Policy, under review.
How does provider sparsity and travel distance to pediatric primary care vary across states?
In our research into pediatric primary care, we examine spatial access, which includes availability, providers’ patient volume or time available for healthcare delivery, and accessibility, the time and/or distance barriers that patients experience in reaching their providers. While concerns about the availability of primary care providers have been expressed within recent health policy, we find that the disparities in availability for pediatric primary care are not as significant as the disparities in accessibility. We find that privately-insured children have the best median accessibility in California, while publicly-insured children have the best median accessibility in Minnesota. The median availability is the lowest in Mississippi for both population groups. The accompanying figure shows travel distance across census tracts for each of the seven states included in our analysis.
