RESUMEN
OBJECTIVE: To evaluate the effect of demographic disparities on language outcomes in a diverse group of children who are deaf or hard of hearing. STUDY DESIGN: Retrospective cohort study. SETTING: UCSF Benioff Children's Hospital (a tertiary care center). METHODS: Forty-four patients aged <18 years were identified with sensorineural hearing loss managed with a behind-the-ear hearing aid or cochlear implant. Demographic and clinical data were extracted from the medical record. The primary outcome measure was the Preschool Language Scales-5 at least 6 months after intervention. Predictors of language outcome were assessed: hearing level at the time of hearing intervention, cochlear implant status, age of identification and intervention, travel time to site of hearing care, home language, race/ethnicity, insurance type, and Access Challenge Index-a novel measure of educational environment and family support based on the Child Cochlear Implant Profile. Multivariate and univariate analysis assessed predictors for association with intervention and receptive, expressive, and total language scores. RESULTS: Overall 82% of patients had cochlear implants. The median age at hearing intervention was 12 months. The sample was 59% female, 52% non-White, and 61% publicly insured, and 20% had a non-English primary home language. Accounting for multiple demographic and clinical predictors, a high Access Challenge Index score was independently associated with longer time to intervention (P = .01) and poorer language outcomes (P < .001). CONCLUSION: Access Challenge Index-a novel comprehensive measure of educational and family environment-is a strong independent predictor of language outcomes in children who are deaf or hard of hearing.
