INTRODUCTION: Children who are deaf or hard-of-hearing (DHH) are at risk for speech and language delay. Language outcomes are worse in DHH children from lower socioeconomic backgrounds, due in part to disparities in access to specialised speech-language therapy. Teletherapy may help improve access to this specialised care and close this language gap. Inclusion of diverse DHH children in prospective randomised clinical trials has been challenging but is necessary to address disparities and pursue hearing health equity. Stakeholder input regarding decisions on study design elements, including comparator groups, masking, assessments and compensation, is necessary to design inclusive studies. We have designed an inclusive, equitable comparativeness effectiveness trial to address disparities in paediatric hearing health. The specific aims of the study are to determine the effect of access to and utilisation of speech-language teletherapy in addressing language disparities in low-income children who are DHH. METHODS AND ANALYSIS: After stakeholder input and pilot data collection, we designed a randomised clinical trial and concurrent longitudinal cohort trial to be conducted at four tertiary childrens hospitals in the USA. Participants will include 210 DHH children aged 0-27 months. 140 of these children will be from lower income households, who will be randomised 1:1 to receive usual care versus usual care plus access to supplemental speech-language teletherapy. 70 children from higher income households will be simultaneously recruited as a comparison cohort. Primary outcome measure will be the Preschool Language Scales Auditory Comprehension subscale standard score, with additional speech, language, hearing and quality of life validated measures as secondary outcomes. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Boards of the participating sites: the University of California, San Francisco (19-28356), Rady Childrens Hospital (804651) and Seattle Childrens Hospital (STUDY00003750). Parents of enrolled children will provide written informed consent for their childs participation. Professional and parent stakeholder groups that have been involved throughout the study design will facilitate dissemination and implementation of study findings via publication and through national and regional organisations.
