Summary SNHL Evaluations:

With the new advancements in screening and testing, the diagnostic evaluation of infants with sensorineural hearing loss (SNHL) has evolved drastically. Additionally, there are several differences in the diagnostic evaluation of SNHL between provinces and territories in Canada. There are currently no published guidelines.

We will review some generalized clinical algorithms which vary depending on province and territory in Canada to guide the diagnostic evaluation of pediatric SNHL. These algorithms include information about the selection and timing of appropriate diagnostic tests, how clinicians can access the dried blood spot, and guidance on the indications for genetic testing. The algorithms were peer reviewed by otolaryngology-head and neck surgeons across the country. A mobile app for both Android and iOS operating systems was created with interactive versions of the algorithms to serve as a point-of-care clinical tool for otolaryngology-head and neck surgeons across Canada.

We will also review how audiologists can be involved in the critical early days of time sensitive investigations.

Learning Objectives:

• To understand the complexity of algorithms, given the differences in access and availability of different tests in different provinces
• To develop an understanding of time sensitive testing once diagnosis of PHL is made
• To explore the possible role of audiologists in initiating evaluations for PHL
• To become aware of the available app which can guide evaluations for SNHL
