Clinical observation led to a concern that due to a higher incidence of outer and middle ear dysfunction in Hispanic newborns and children, screening could result in disparate failure rates, with a larger number of these infants requiring further testing. This result would warrant changes in current protocols, as well as screener training,and parent counseling practices. Between January and July of 2000, 1407 newborns were tested utilizing distortion product otoacoustic emission screening protocols. Of those infants,only 68 failed, yeilding a higher than average overall program referral rate of 5%. It is hypothesized that since later reported referral rates for this program fall below 1%, the individuals performing the screenings had not yet become experienced enough to yield low refer rates. In addtion, initial screens are not repeated in this program due to staffing and funding issues, which may contribute to higher than average fail rates. More important, however, results indicated that there is indeed a difference in failure rates as a funciton of ethnicity, with a greater proportion of Hispanic and African-American and "Other" newborn referrals that Caucasian or Asian newborns. This difference, however, was not significantly reliable. It is hypothesized that this difference may be the result of a generally lower socioeconomic status and access to medical care within urban minority populations in Hillsborough County, Florida. Implications are discussed. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

A research thesis submitted for the degree of Doctor of Philosophy in Audiology in the Faculty of Humanities the University of the Witwatersrand March 2016. / Purpose: The main objective of the current study was to explore risk-based new-born hearing screening within a developing country by conducting early hearing detection in high-risk neonates within an academic hospital complex in Gauteng, South Africa. Specific objectives describing the case history factors and audio logical function in a group of high-risk determining the relationship between the case history factors and audio logical establishing the true-positive (TP) and true-negative (TN) results with different combinations of screening measures; establishing the percentage of TP and NT screening results in the total sample; and exploring the factors associated with follow-up return rate for hearing screening and diagnostic audio logical assessment. / GR2017
