Description:
This is a systematic review of randomized and non-randomized controlled trials investigating the accuracy and effectiveness of hearing screening in newborns and investigating the effects of early intervention.

Question(s)/Aim(s) Addressed:
Question not specifically stated.

Population:
Children up to 10 years.

Intervention/Assessment:
Otoacoustic emissions and/or auditory brainstem response.

Number of Studies Included:
17

Years Included:
Not stated. Most recently published study included was from 2007.

Conclusions:

Permanent Childhood Hearing Loss

  • Screening/Assessment

    • Screening

      • General Findings

        • “There is a lack of high-quality evidence regarding all elements of newborn hearing screening” (p. 12).Because of the lack of reliable studies, possible harms from neonatal hearing screening could not be evaluated” (p. 11).

      • Physiologic

        • “No overall reliable evaluation is possible for the diagnostic accuracy of otoacoustic emissions (OAE) and auditory brain stem response (ABR) as initial screening tests, as there has been no evaluation in an adequately large group of children without risk factors” (p. 11).

  • Treatment

    • General Findings

      • "There is evidence that early treatment of children with hearing impairments is advantageous for language development. However, the included studies do not allow for any confident conclusions” (p. 11).
