Description:
This is a review of studies investigating the benefits and harms of universal newborn hearing screening (UNHS) in the detection of hearing impairment and patient-relevant therapy goals.

Question(s)/Aim(s) Addressed:

  1. What is the effectiveness of screening programs?

  2. What is the effectiveness of delivering treatment at different time points (early versus later)?

  3. What is the quality of specific diagnostic procedures used in screening?

Population:
Newborns and children through age 10.

Intervention/Assessment:
Universal newborn hearing screening

Number of Studies Included:
10

Years Included:
Through 2006

Conclusions:

Permanent Childhood Hearing Loss

      • General Findings

        • "UNHS can improve the chances that a child with congenital hearing impairment is diagnosed and treated at an earlier stage. It cannot be certainly inferred from the studies available what consequences this has for the development of these children" (p. 5).

        • "There are indications (not evidence) that children with hearing impairment identified by UNHS have advantages in language development. The comparison between children treated earlier vs. those treated later also provides indications that children with earlier treatment may have advantages in language development" (p. 5).

        • "It is insufficiently investigated how newborn hearing screening affects other outcomes relevant to the children, such as quality of life, development at school, and occupational or social situation" (p. 5).
