    Follow-up brainstem electric response audiometry (BERA) testing at four months is crucial for identifying hearing loss in at-risk infants. This approach is more reliable than predischarge screening for determining habilitation needs.

    Area of Science:

    • Audiology
    • Neonatal Care
    • Pediatric Hearing

    Background:

    • Neonatal hearing screening is vital for early detection of hearing loss.
    • Brainstem electric response audiometry (BERA) is a key diagnostic tool.
    • Identifying hearing loss in at-risk infants requires accurate and timely assessment.

    Purpose of the Study:

    • To evaluate the effectiveness of screening and diagnostic Brainstem Electric Response Audiometry (BERA) in at-risk infants.
    • To compare predischarge BERA results with follow-up BERA at four months.
    • To determine the optimal timing for BERA testing to guide habilitation.

    Main Methods:

    • Conducted screening and diagnostic BERA on at-risk infants before hospital discharge.
    • Repeated detailed BERA at approximately four months of age.

  • Analyzed results from 2,597 risk assessments, with 379 infants tested.

    • Main Results:

    • The 40 dB click screening showed good specificity but moderate sensitivity.
    • Follow-up BERA identified 25 cases of hearing loss, including 12 with moderate loss.
    • Discrepancies between predischarge and follow-up BERA were noted, particularly for mild losses, with both resolution and emergence of hearing loss observed.

    Conclusions:

    • Four-month follow-up BERA is a more reliable determinant for habilitation than predischarge testing.
    • Click BERA evaluations alone are insufficient; frequency-specific BERA is recommended.
    • Timing of BERA testing significantly impacts the accurate assessment and management of infant hearing loss.
