TRICARE, the U.S. Department of Defense insurance program for eligible service members and their dependents, provides health care coverage to nearly 2 million children under the age of 18. Survey data and prior evaluations indicate that TRICARE-covered children face challenges in accessing pediatric health care, with the greatest challenges among children who have experienced frequent relocations and children with special health care needs. However, TRICARE has not measured pediatric patient experiences in accessing care since 2010. To fill this gap, RAND researchers analyzed national survey data on the experiences of caregivers of TRICARE-covered children and children with commercial insurance, public insurance, and no insurance to identify differences in access to pediatric care, necessary referrals, care coordination support, ability to pay medical bills, and other factors. Additional analyses highlight variations between children with different TRICARE plans, between children who have changed addresses more and less frequently, and between children with special health care needs and those without. The findings should help inform efforts to increase access to care for children across the Military Health System, as well as improvements to programs designed to support military families during relocations and those with children who have special health care needs.
