Optimizing CI Outcomes in Children with Congenital Hearing Loss
09-10, 07:00–07:30 (Europe/Istanbul), Hearing Implant 2

Background. Permanent childhood hearing loss has a negative impact on children’s development. Early detection via universal newborn hearing screening makes early intervention possible. Evidence on how and why early intervention influences outcomes of children with hearing loss at school age is lacking. This paper draws on findings from the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study, a prospective population-based study in Australia.

Objective. To examine the influence of early hearing intervention on the outcomes of children who are deaf or hard of hearing.

Method. Three-hundred and sixty-seven children completed assessments at earlier time points and at 9 years of age. In the cohort, 231 were using hearing aids and 158 were using cochlear implants. Standardized measures of language, cognitive abilities, and speech perception were directly administered. Quality of life was assessed using standardized questionnaires. The relationships among demographic characteristics, age at fitting of hearing aids or cochlear implants, and children’s outcomes were examined using multiple regression analysis and structural equation modelling. 

Result. The modelling is consistent with verbal short-term memory having a mediating effect on multiple outcomes. Better verbal short-term memory is associated with no additional disabilities, earlier age at cochlear implant activation, use of an oral communication mode in early intervention, and higher maternal education. In turn, verbal short-term memory directly and positively affects speech perception, language and quality of life.

Conclusion. This study found evidence consistent with early hearing intervention having a positive effect on speech perception and language via its effect on verbal short-term memory. Children who had better language also had better quality of life. The importance of early hearing for cognitive development lends support to early detection and early hearing intervention, including streamlining pathways for early CI activation. The implications for evidence-based clinical practice will be discussed.
