Purpose Many children with severe intellectual and developmental disabilities are at a higher risk for hearing loss than their peers who are typically developing. Unfortunately, they do not consistently participate in routine school-based hearing screenings. The current study investigated the feasibility of increasing their participation using an otoacoustic emissions protocol and documented results relative to student educational profiles. Method A total of 43 students with significant cognitive disabilities enrolled at a public school exclusively serving this population participated in the study. All but 9, who were excluded because of known hearing loss, were screened by a licensed audiologist assisted by audiology doctoral students. The protocol included otoscopy, tympanometry, distortion product otoacoustic emissions (DPOAEs), and teacher surveys. Results DPOAE screening was attempted on 33 students without previously diagnosed hearing loss and successfully completed for 26 (78.8%). Two students (4.6%) with absent otoacoustic emissions and normal tympanograms were referred for further assessment due to concerns about possible sensorineural hearing loss in one or both ears, and 10 (23.3%) had abnormal tympanograms in one or both ears. Conclusions Considering the high risk of sensorineural hearing loss for children with significant disabilities, it is important for them to be included in school hearing screenings. The results of this study demonstrate the feasibility of using DPOAEs for school-based hearing screenings with this population with an interprofessional team of licensed audiologists, educators, and speech-language pathologists. The results further suggest that students with significant disabilities and hearing loss may be unidentified and underserved. Given the complex needs of this population, an interprofessional practice model for hearing screenings and intervention services is recommended.
