Newborn Infants Tested by Automated Auditory Brainstem Response (AABR) Measurement Screening Program

Screened before discharge10 37296.3
Screened after discharge2122.0
Not screened*1891.7
Total births10 773100
  • * 101 = moved, 80 = noncompliant, 8 = parents refused, 1 = not screened because of continuing hospitalization (not included in this calculation). Infants who died are not included in our study population.

  • Total ear-specific data on this group was not kept. If an infant passed the initial screen in one or both ears, she or he was discharged and a note was made in the chart if one ear failed, but these infants were not tracked. During the first 3 years of the program, infants recalled were tested behaviorally at age 6 to 7 months; sound field visual response audiometry was done and ear-specific data was not available. By year 4, we screened all recalled infants by AABR.
