Hearing Loss clinical trials at University of California Health

Children who are deaf or hard-of-hearing (D/HH) are at risk of speech and language delays, which can be mitigated through early identification and intervention. Identifying hearing loss (HL) during preschool is crucial, but the most effective hearing screening method for preschoolers remains uncertain. The purpose of this study is to learn whether, compared to the gold-standard two-stage Pure-tone audiometry (PTA) + otoacoustic emissions (OAE) screening (TS-PO), single-stage OAE (SS-O) screening alone is not inferior at identifying hearing loss when performed in a community-based preschool setting. This study holds the potential to improve early hearing loss detection and intervention among D/HH children, reducing the likelihood of speech and language delays. A diverse group of 28,000 preschool-age children across community-based preschool centers will be recruited. The intervention involves all subjects undergoing both PTA and OAE screening, with the order determined through randomization. Children who show potential hearing issues based on screening results or teacher concerns will receive further testing to determine the final hearing outcome. Group allocation will be post-hoc, based on their screening results. In addition to the primary objective, the study will compare other hearing screening measures and outcomes between the two methods (TS-PO and SS-O). This approach aims to reflect the real-life effectiveness of hearing screening in a diverse population. Ultimately, the study seeks to provide insights into an optimal hearing screening method that could prevent speech and language delays among D/HH children.

This study seeks to determine the effectiveness of speech/language teletherapy to address disparities in speech and language outcomes in children who are deaf or hard-of-hearing (D/HH). The investigators will enroll D/HH children aged 0-27 months. 140 children who are publicly insured will be randomized to receive usual clinical care or to be given access to an 18-month course of speech-language teletherapy program. 70 children who are privately insured will also be enrolled and will receive usual care. Children will undergo, at baseline and every 9 months thereafter to a study endpoint of 18 months, for a total of 3 timepoints, a battery of in-person and parent-report assessments designed to provide a comprehensive measurement of the child's auditory function, speech, verbal- and non-verbal communication, spoken language, and quality of life.
