Outcome Evaluation

Question 1

FU schedule

Answer 1

A minimum of two FU visits within the first two months

This needs to be varied on a case-by-case basis, ANSD, fluctuating HL needs more frequent FU

Question 2

FU appt

Answer 2

Hx 
Otoscopy
Immittance
EMI if needed
RECD when new EM made to account for growth & development
Subsequent adjustments on REMs

Question 3

Outcome measures and the purpose

Answer 3

Questionnaires (LittleEARS, PEACH)
Behavioural reports from the family
Age appropriate aided speech perception testing (Ling-6)
Cortical AEP in children w/ANSD or where auditory behaviour is uncertain
Purpose: to ensure HAs are providing access to conversational speech (65dB SPL/50-55dBA/45dB HL)

Question 4

Unsatisfactory outcome from amplification…

Answer 4

1. CI referral

2. Manual communication systems discussed with family in consultation with the AODC

Question 5

LittleEARS

Answer 5

Auditory development check

Question 6

PEACH

Answer 6

Functional performance

Question 7

FU 간격

Answer 7

Every 3 months until 2

Every 6 months until 5

Question 8

Why do we use cortical for validating hearing aids and what do we look for?

Answer 8

We use CAEP because we can reliably measure responses in infants (sound stimulus long enough to assess HA fitting, can assess not only subcortical but up to the cortex).

We look for P1-N1-P2, mostly P1 responses as P1 predominates up to 7yo of age then slowly depresses.

Question 9

Why not use ABR for validation of HA?

Answer 9

1. Sound stimulus too brief to activate HA compression features; so cannot assess those features
2. Contamination of early responses by loud speaker
3. Stimulus used for ABR is different from speech hence HA perform differently.
