Identification of Hearing Loss Post Newborn Hearing Screening in Children with Known or Suspected Neurodevelopmental Involvement
The Joint Committee on Infant Hearing (JCIH) and Early Hearing Detection and Intervention (EHDI) program promotes the goal of early identification and prompt intervention for infants and young children with hearing loss (HL). Much of the focus is on completion of and follow-up for the newborn hearing screening (NBHS). However, provision is also made for identification of HL that presents post NBHS.
Infants who passed their NBHS may develop, or show evidence of, infant or childhood HL post NBHS. Additionally, infants with minimal/mild HL are likely to pass NBHS, as current screening technologies are effective in identifying hearing thresholds of approximately 35–40 dB HL and greater (Norton et al., 2000a).
If 1-2 infants out of every 1,000 are diagnosed as deaf or hard of hearing at birth, it is estimated that another 1-2 per 1,000 will later be diagnosed with permanent HL (Mehra, et.al., 2009). This may reflect delayed-onset HL associated with certain diagnoses/atypical neurodevelopment, as well as missed conductive, sensory, or neural HL at the time of NBHS. In a report (Watkin & Baldwin, 2012), the prevalence of children confirmed as deaf or hard of hearing by school age was 3.65/1000 compared to a neonatal yield of 1.79/1000.
Although Kennedy Krieger Institute is not a primary site for NBHS, it provides diagnostic and habilitative care for infants post NICU and children of all ages for whom there is known or suspected neurodevelopmental involvement. In this study we will review the literature for major groups of diagnoses seen at Kennedy Krieger Institute (e.g., ASD, Down syndrome, TBI, prematurity, epilepsy, ID, mitochondrial disorders) to determine the prevalence of comorbid HL, as well as the timeline of the development of HL. This information will be used to develop guidelines for referrals to audiology from other disciplines and guidelines for audiologic monitoring.
- To be aware of and use guidelines for referrals to audiology from other disciplines and guidelines for audiologic monitoring.
- To gain a better understanding of the prevalence of comorbid hearing loss in children with known or suspected neurodevelopmental involvement.
- Increase medical professionals’ awareness of the signs and symptoms of childhood hearing loss.
