This study examined data from the 2005-2006 National Survey of Children with Special Health Care Needs to assess the relationship among children with asthma between a reported medical home and emergency department (ED) use. The authors used 21 questions to measure 6 medical home components: personal doctor/nurse, family-centered, compassionate, culturally effective and comprehensive care, and effective care coordination. Weighted zero-inflated Poisson regression analyses assessed the independent effects of having a medical home on annual number of child ED visits while controlling for child and parental characteristics, and the differential likelihood of securing a medical home. Nearly half (49.9%) of asthmatic children had a medical home. Receiving primary care in a medical home was associated with fewer ED visits (incidence rate ratio = 0.93; 95% confidence interval = 0.89-0.97). A medical home in which physicians and parents share responsibility for ensuring that children have access to needed services may improve child and family outcomes for children with asthma.
