The use of hearing tests to assess otitis media with effusion in children with Down syndrome.

ABSTRACT

BACKGROUND: Down syndrome is associated with an increased risk for otitis media with effusion (OME), a childhood condition in which fluid accumulates in the middle ear, potentially leading to hearing loss. The American Academy of Pediatrics Down syndrome guidelines and the American Academy of Otolaryngology - Head and Neck Surgery OME guidelines recommend hearing testing to assess the hearing status of children with Down syndrome diagnosed with OME. METHODS: Through an Institutional Review Board approved retrospective chart review at Children's Mercy, this project assessed how clinical factors affect the frequency in which children with Down syndrome receive hearing testing after diagnosis of OME. The study included data from all children with Down syndrome between 1 and 8 years old diagnosed with OME in the Down syndrome, general pediatrics, and otolaryngology clinics between 2018 and 2020. Demographics and clinical factors, including clinic setting, were collected. RESULTS: Of the 124 patients identified, 91.1 % were diagnosed with OME in the otolaryngology clinic and 33.1 % received hearing testing. While most diagnoses occurred in the otolaryngology clinic, a higher proportion of hearing testing at the time of diagnosis occurred in the Down syndrome clinic. This could be explained by the fact that the Down syndrome clinic is a multidisciplinary clinic, where yearly visits include hearing screening. Bivariate analysis using chi-square or Fisher's tests showed that clinic setting had a significant association (p-value <0.001) with hearing testing. However, logistic regression depicted all clinical factors had an insignificant effect on hearing testing at 5 % significance. CONCLUSION: While results indicate hearing testing is largely not performed to assess OME early in otolaryngology clinics, they may be used to assess intervention efficacy post-diagnosis. Results point to the importance of Down syndrome clinics in early diagnosis of hearing loss leading to timely referrals to otolaryngology clinics which diagnose and manage OME in children with Down syndrome.
