Background: The importance of the medical home for children has been demonstrated but has not been examined comprehensively for adolescents. Adolescence is a unique period of physical, cognitive, and psychosocial changes when many mental disorders first emerge; thus, receiving care within a medical home could improve well-being. This study examines rates of medical home attainment and its components for adolescents and subgroups, including those with mental health conditions. Methods: Utilizing the 2007 National Survey of Children's Health, we determined the following for adolescents aged 10 to 17 years (n = 45 897): 1) rates of medical home attainment and its 5 components (usual source of care, having a personal doctor, and receiving needed referrals, effective care coordination, and family-centered care); and 2) subgroup differences; gender, race/ethnicity, income, insurance, region, language spoken at home, respondent education, and the presence of mental health conditions. Results: Fifty-four percent of adolescents had a past-year medical home. Rates were lower for minority youth compared to whites; lower-income and uninsured youth; those in households that are non-English speaking in which the respondent did not have some college; and those with mental health as opposed to physical health conditions (all P < .01). Patterns of disparities in the medical home components were similar, and rates were lowest for effective care coordination and family-centered care components. Conclusions: Nearly half of adolescents lacked a medical home in the past year. Even lower rates for subgroups highlight the need to increase access to comprehensive quality health care. Efforts to improve effective care coordination and family-centered care could result in higher quality of care for all children and adolescents, and specifically for disadvantaged adolescents and those with mental health conditions. © 2013 Academic Pediatric Association.
