Title: 'Prevalence of Risk Factors Associated with Congenital and Delayed Onset Hearing Loss in Iowa’s Children'
Track: 6 - Follow-up, Tracking and Data Management
Keyword(s): Risk factors, congenital hearing loss, delayed onset hearing loss, eSP
Learning Objectives:
  1. Identify which risk factors are most associated with hearing loss present at birth, and by age three years within study population.
  2. Report what percentage of children with a given risk factor is affected with congenital or delayed hearing loss within study population.
  3. Discuss impact of findings to future risk factor reporting and follow up recommendations


In their 2007 position statement, the Joint Committee on Infant Hearing identified eleven risk factors related to congenital, delayed onset, or progressive hearing loss in infants and children. The continual expansion of universal newborn hearing screening (UNHS) scope and its progressive reliability has enabled professionals in recent years to merge risk factor reporting within UNHS protocols. In Iowa, EHDI legislation mandates the reporting of these risk factors by healthcare providers. Information is entered into the EHDI online e-Screener Plus (eSP) database, which tracks hearing related healthcare status such as birth information, hearing screening outcomes, subsequent follow up visits, and now, risk factors. This poster will detail the reported prevalence of the eleven JCIH risk factors in children born in Iowa between January 2007 and December 2010 diagnosed with congenital or delayed onset hearing loss present by 3 years of age. Statistics will be broken down to identify overall prevalence of individual risk factors, and percentages of children with an individual risk factor and congenital/delayed onset hearing loss. The reporting methods will be discussed, as will suggestions for future improvements in reporting. Questions regarding to the implications for follow up recommendations made by EHDI will also be posed.
