Health care utilization and spending among privately insured children with medical complexity

Abstract

Children with medical complexity have high health service utilization and health expenditures that can impose significant financial burdens. This study examined these issues for families with children enrolled in US private health plans. Using IBM Watson/Truven Analytics℠ MarketScan® commercial claims and encounters data (2012–2014), we analyzed through regression models, the differences in health care utilization and spending of disaggregated health care services by health plan types and children’s medical complexity levels. Children in consumer-driven and high-deductible plans had much higher out-of-pocket spending and cost shares than those in health maintenance organizations and preferred provider organizations (PPOs). Children with complex chronic conditions had higher service utilization and out-of-pocket expenditures while having lower cost shares on various categories of services than those without any chronic condition. Compared to families covered by PPOs, those with high-deductible or consumer-driven plans were 2.7 and 1.7 times more likely to spend over US$1000 out of pocket on their children’s medical care, respectively. Families with higher complexity levels were more likely to experience financial burdens from expenditures on children’s medical services. In conclusion, policymakers and families with children need to be cognizant of the significant financial burdens that can arise from children’s complex medical needs and health plan demand-side cost sharing.
