How does being part of a pediatric accountable care organization impact health service use for children with disabilities?

Abstract

OBJECTIVE\nTo examine the impact of a Medicaid-serving pediatric accountable care organization (ACO) on health service use by children who qualify for Medicaid by virtue of a disability under the aged, blind, and disabled (ABD) eligibility criteria.\n\n\nDATA SOURCES/STUDY SETTING\nWe evaluated a 2013 Ohio policy change that effectively moved ABD Medicaid children into an ACO model of care using Ohio Medicaid administrative claims data for years 2011-2016.\n\n\nSTUDY DESIGN\nWe used a difference-in-difference design to examine changes in patterns of health care service use by ABD-enrolled children before and after enrolling in an ACO compared with ABD-enrolled children enrolled in non-ACO managed care plans.\n\n\nDATA COLLECTION/EXTRACTION METHODS\nWe identified 17\xa0356 children who resided in 34 of 88 counties as the ACO intervention group and 47\xa0026 ABD-enrolled children who resided outside of the ACO region as non-ACO controls.\n\n\nPRINCIPAL FINDINGS\nBeing part of the ACO increased adolescent preventative service and decreased use of ADHD medications as compared to similar children in non-ACO capitated managed care plans. Relative home health service use decreased for children in the ACO.\n\n\nCONCLUSIONS\nOur overall results indicate that being part of an ACO may improve quality in certain areas, such as adolescent well-child visits, though there may be room for improvement in other areas considered important by patients and their families such as home health service.
