Does receiving care in a medical home reduce racial/ethnic disparities in ED visits among children with asthma in the United States?

Abstract

Evidence has shown the implementation of medical home model improves care quality and outcomes. However, it is not clear whether receiving care from a medical home has any impact on racial/ethnic disparities in emergency department (ED) use by children with asthma. This study using the US National Survey of Children with Special Health Care Needs, 2009-2010, estimated racial/ethnic disparities in ED use. Generalized liner models were used to examine factors associated with ED use. Racial/ethnic differences in ED use were attenuated after adjusting for socio-economic variables. Ratios of prevalence ratios were calculated to examine the effect modification of medical home on ED use associated with race/ethnicity. The adjusted prevalence ratio of ED use of the Black to non-Hispanic White was 1.51 (95% confidence interval (CI): 1.36-1.67) with medical home and 1.35 (95% CI: 1.24-1.47) without medical home. Among those with care from a medical home Latino children had higher ED use compared with White children. There is no evidence that the self-reported care from a medical home narrows the gaps in ED use between non-Hispanic White and Black or Latino children with asthma.
