Audiology

The Tri-Regional Infant Hearing Program contracts with local audiologists to provide hearing assessments for children referred from the program. These audiologists are registered with the Provincial Infant Hearing Program and are trained on state of the art equipment and follow the protocols of the program.

If hearing loss is identified, the infant is referred for medical assessment.

High Risk Monitoring

Who is eligible for High Risk Monitoring?

Infants who are identified with a risk factor for late onset or progressive hearing loss and have received a "PASS" result on an earlier screening will be eligible for the High Risk Monitoring Protocol.

What is the High Risk Monitoring Protocol?

This is an evidence based protocol using various steps between 4 and 30 months. The steps include:

• 4 months corrected age - Auditory Brainstem Response (ABR) screen by an IHP trained audiologist
• 8-12 months corrected age - Visual Response Audiometry (VRA) by an IHP trained audiologist
• 18 months corrected age - a telephone auditory checklist which is standardized (LittlEars Auditory Checklist) by a screener with the program
• 30 months corrected age - access to a development screening

What if my child gets a PASS RESULT?

Infants who "PASS" any of the steps are recommended for the next step. At 30 months of age, the child is no longer monitored by the program.

What if my child gets a REFER RESULT?

An infant having a "REFER" result on any surveillance will have a complete audiology diagnostic assessment.

If a child does not meet the expected score on the LittlEars Auditory Checklist, the screener will recommend a referral to an IHP trained audiologist for diagnostic assessment. With parental consent, screeners will also initiate a referral to the Preschool Speech and Language Program.
