By rescreening all infants before hospital discharge, the false-positive rate of UNHS performed using automated ABR can be reduced to <1%. However, for the false-positive results that do occur, any long-lasting and detrimental emotional impact between mother and infant seems to be small and could be reduced even more with improved understanding about UNHS.

ABSTRACT. Background and Objectives. The falsepositive rates of previously reported universal newborn hearing screening (UNHS) programs range between 2.5% and 8%. Critics of UNHS programs have claimed that this rate is too high and might lead to a number of the negative effects produced by false-positive screening tests, namely emotional trauma, disease labeling, iatrogenesis from unnecessary testing, and increased expense in terms of time and money.We previously reported, based on some preliminary data, that as many as 80% of newborns who failed the initial hearing screen subsequently passed when they were retested the following day, before being discharged from the hospital. We now present the results of this intervention for our entire UNHS program during a 7-month period.Methods. We analyzed data from 3142 non-neonatal intensive care unit infants screened with an automated auditory brainstem response at the Women's Hospital of Greensboro from November 1, 1999 to May 31, 2000. A protocol was developed wherein all infants who failed the initial UNHS were rescreened with another automated auditory brainstem response before hospital discharge. Data collected included pass/fail rates during the inpatient stay as well as follow-up data and risk factors for congenital hearing loss.Results. Confirmed hearing loss occurred in 8 nonneonatal intensive care unit infants, a rate of 2.5/1000. Eighty percent of newborns who failed the initial hearing screen passed on rescreening before hospital discharge. This produced a false-positive rate of 0.8% and a corresponding positive predictive value of 24%. If inhospital rescreening had not occurred, our false-positive rate and positive predictive value would have been 3.9% and 6.1%, respectively.Conclusions. Our simple intervention of rescreening all infants who failed their initial UNHS before hospital discharge reduced the false-positive rate of UNHS to 0.8%. We suggest that this simple, inexpensive intervention should be instituted for all similar UNHS programs. Pediatrics 2001;107(3).

A 36-week gestation newborn was admitted to the neonatal intensive care unit for treatment of primary pulmonary hypertension and possible sepsis. The infant developed hyperbilirubinemia on day 4 of life and peaked on day 5 at a total serum bilirubin of 19 mg/dL. Phototherapy was started on day 4 and continued for 5 days. On day 8 of life, ibuprofen was started for fever; a concurrent total serum bilirubin was 15.7 mg/dL. The subsequent hospital course was uneventful, and discharge occurred on day 22 of life. Because the patient failed a hearing screen at discharge, he was referred for a diagnostic audiology workup. He subsequently failed formal audiometric testing on two occasions one week apart, and was given a diagnosis of auditory dys-synchrony and/or auditory neuropathy, consistent with kernicterus. At 5½ months of age, he was reported to be hypotonic and to have frequent arching movements. Since the total serum bilirubin did not exceed 19 mg/dL, concern was raised that ibuprofen may have caused displacement of bilirubin from its albumin binding site, resulting in kernicterus due to excessive unbound bilirubin concentrations. Ibuprofen should be administered with caution in preterm infants at risk for kernicterus.
