OBJECTIVE: To investigate whether children in Michigan with private insurance have better hospitalization-related outcomes than those with public or no insurance. STUDY DESIGN: Population-based hospitalization rates were calculated for newborns and children aged <18 years in Michigan for the years 2001-2006 and stratified by age, disease grouping, and health insurance status using inpatient records from the Michigan Inpatient Database and population estimates from the US Census Current Population Survey. RESULTS: Michigan children with public/no insurance had significantly higher overall hospital admission rates and admission rates for ambulatory-sensitive conditions, and were more likely to be admitted through the emergency room, compared with those with private health insurance. Similarly, newborns with public/no insurance had significantly higher rates of hospitalization-related outcomes. Hospital charges per child were higher in the public/no insurance population, translating to potential excess charges of between $309.8 and $401.8 million in 2006. CONCLUSIONS: There are disparities in health outcomes and charges between Michigan children and newborns with public/no insurance and those with private health insurance, presenting a significant opportunity to improve the efficiency and efficacy of care.
