Consideration of a Targeted Cytomegalovirus Screening for Infants who Fail Newborn Hearing Screening.
It has been estimated that 15-20% of cases of bilateral moderate to profound sensorineural hearing loss in children are due to congenital cytomegalovirus (cCMV) infection1. Due to the asymptomatic nature of cytomegalovirus infection in both pregnant women and affected infants at birth, cCMV is often not identified early, and necessary medical interventions are not instituted until after sequelae are present. The association between cCMV and permanent hearing loss in children has initiated legislation in some states mandating 1) maternal and provider education about cCMV infection 2) targeted cCMV screening following a failed newborn hearing screening (NBHS) or 3) both education and targeted cCMV screening following a failed NBHS. To assess the impact of this legislation, literature and available data from states and countries which have implemented targeted cCMV screening will be compared to available data from states which do not mandate a cCMV screening following a failed NBHS to determine the rate of infants identified with cCMV secondary to a failed NBHS. In addition, information about the efficacy of early intervention for both the treatment of cCMV infection and the management of permanent hearing loss will be investigated, with the aim being to determine the overall merits of cCMV screening following a failed NBHS.

- Assessment of the efficacy of targeted cCMV screening at accurately identifying cCMV secondary to congenital hearing loss.
- Comparison of the overall effectiveness of mandated cCMV screening programs following a failed newborn hearing screening.
- Further investigation of outcomes and implementation of early interventions for cCMV and SNHL.
