Background/aims: A large proportion of preschool children have hearing loss and ear disease, mostly in the form of otitis media with effusion (OME). Early detection and treatment of such conditions are critical for normal speech and language development. The aim of this study is to establish the feasibility of screening three-year-olds in Early Learning Centres (ELCs) using distortion product otoacoustic emissions (DPOAEs). More specifically, this research helps to facilitate earlier detection of significant ear and hearing problems to enable timely treatment and improve hearing and developmental outcomes. Methods: ELCs were recruited within the Counties Manukau District Health Board (CMDHB) geographical catchment area and caregiver consent was gathered from three-year-old children who were interested in participating. Using a two-staged screening pathway consisting of otoscopy, DPOAE, and tympanometry screening, children with hearing loss and/or middle ear problems were identified based on a set of rescreen or immediate referral to audiology services criteria. Findings: From the seven ELCs that consented to participate, 61 children (mean (M) age = 3.5 years, standard deviation (SD) = 0.3) underwent a first screen and 12 children completed a rescreen. All children screened were compliant enough for the tests to be completed to a satisfactory level. Of the 61 children screened, 38 (62.3%) passed the screening pathway (either at their first screen or rescreen); five (8.2%) were referred immediately to audiology after their first screen; seven (11.5%) were referred to audiology due to not passing their rescreen in both ears; three (4.9%) were referred to audiology due to unilateral rescreen referrals; and eight (13.1%) children were lost to follow up. A total of 23 children (37.7%) were ultimately referred to audiology services. No wax removal services were available for children under age four, so the feasibility of this pathway is questioned. Conclusions: Screening three-year-old children with DPOAEs as part of a screening pathway detected a high prevalence of significant ear problems. A substantial proportion of recruited participants were also lost to follow up, which provides information about the feasibility of this screening pathway and what aspects need improvement. This study confirms the feasibility of using DPOAEs in an ELC-based screening programme to screen for ear disease and hearing loss in three-year-old children. |
