Disparities in spatial access to pediatric primary care in Georgia are significant
Disparities in spatial access to pediatric primary care in Georgia are significant, and resistant to many policy interventions, suggesting the need for major changes to the structure of Georgia's pediatric healthcare provider network. Two examples of interventions include changing the percentage of physicians accepting Medicaid patients (left plot) and changing the proportion of physicians' caseloads that they are willing to devote to Medicaid patients (right plot) where both changes are with respect to the status quo. The state average for the travel cost for the patients with Medicaid changes very little from the status quo when increasing these rates whereas it affects the travel cost significantly if decreasing these rates.
