Learning Objectives: 1. Identify infants at risk for delayed onset hearing loss. 2. Determine which infants are at greater risk for rapidly progressive hearing loss 3. Establish timelines for monitoring hearing in children at risk for delayed onset hearing loss.


Risk indicators were first proposed by the Joint Committee on Infant Hearing (JCIH) in 1973. At that time, the available technology did not allow for universal screening. Therefore, risk indicators were used to identify infants at risk for congenital, as well as, delayed onset hearing loss. In the era of Universal Newborn Hearing Screening, these indicators remain important to identify infants who pass an initial screen but are at risk for delayed onset hearing loss. The JCIH 2007 Position Statement recommends that all children with a risk indicator have an audiologic evaluation “…at least once by 24-30 months of age regardless of their newborn hearing screening results.” The Position Statement goes on to state that infants with specific risk factors (CMV and ECMO) should be monitored closely. Through a retrospective review of infants with confirmed delayed onset hearing loss prior to 48 months of age, we aim to evaluate the utility of risk indicators for identification of children at risk for delayed onset hearing loss.. We also aim to determine which risk factors warrant close monitoring. Data from a retrospective review of twenty years of newborn hearing screening at the University of Michigan Medical Center will be analyzed.
