RESUMO
OBJECTIVE: Sociodemographic disparities of cochlear implantation in children have been reported. This study sought to determine if disparities in children receiving cochlear implants have narrowed, widened or remained constant. METHODS: Children 18 years or younger who underwent cochlear implantation from 1997 to 2012 were selected using the Kids' Inpatient Database. Demographic data included primary insurance payer, income quartile and race. The Cochran-Armitage test was used to determine if trends were significant. Prevalence rates of cochlear implantation by race were generated. A Poisson regression model was used to evaluate the rates of cochlear implantation within each racial group. RESULTS: The proportion of children receiving cochlear implants with private insurance decreased from 79.3% to 42.6% (pâ¯<â¯.0001), whereas children with Medicaid increased from 17.4% to 35.2% (pâ¯<â¯.0001). Proportion of implanted children from the lowest two income quartiles increased from 15.5% to 24.4% (pâ¯<â¯.0001) and 10.3%-21.8% (pâ¯<â¯.0035), respectively. Rates of implantation among children from income quartile four decreased from 50.9% to 35.3% (pâ¯<â¯.0001). White children were implanted twice as often as Black or Hispanic children (pâ¯=â¯.007 and pâ¯=â¯.0012 respectively). Asian children were implanted more than twice as often as Black or Hispanic Children (pâ¯=â¯.0154 and pâ¯=â¯.0098 respectively). CONCLUSIONS: Income and insurance disparities have narrowed within the inpatient pediatric cochlear implantation cohort. Racial disparities still exist. White and Asian children are implanted at higher rates than Black or Hispanic children.
