Introduction Children who are deaf or hard of hearing (DHH) are at risk for poor developmental outcomes related to incomplete language access. Evidence based interventions are available to improve early access to language. With a better understanding of caring for DHH children, pediatricians will be more prepared to work with families in improving outcomes for this population. To date, there are no formal curricula on educating pediatric trainees on childhood hearing differences. Methods The authors designed a novel pilot curriculum to educate pediatric trainees on caring for DHH children, including screening, diagnosis, signed languages, and hearing technologies. The curriculum was delivered to pediatric interns in a 1-hour seminar. Pre-lecture, immediate post-lecture, and 6-month post-lecture surveys were developed and conducted to evaluate the effectiveness of the curriculum. Descriptive statistics were used to determine differences in understanding concepts before and after the curricular intervention. Results A total of 55 residents participated in the curriculum over a 14-month study period from 2018 to 2019. There were significant differences in responses between the pre- and post- surveys related to residents' understanding of childhood deafness and their confidence in their ability to care for DHH children. Conclusion Pediatric trainees gained an understanding of the challenges faced by DHH children and of the interventions that aim to provide them with access to language during the critical period of development. As a result, trainees will be in a better position to care for patients and their families after a new diagnosis of a hearing difference and guide them through early language-based interventions.
