Q

What 3 factors do we look at when considering if the patient is a good candidate for amplification?

A
  1. Audiological profile (audiogram, speech testing scores, tinnitus, hyperacusis, performance in speech in noise, etc.)
  2. Communication needs (how to positively impact patients in areas that are important to them)
  3. Motivation (does the patient have the desire for assistance through amplification?)

Q

How do we gauge success?

A
  • Verification and validation measures with counselling, and follow-up
  • Verification: verify the HA is meeting the presecription through real ear measures
  • Validation: are the HAs making a difference in the environment that they are supposed to be working in

Q

What are 4 physical considerations when thinking about HAs?

A
  1. Can the ear (pinna and ear canal) support an aid?
  2. Is the canal occluded with debris (infection, cerumen, foreign body)
  3. What the does canal look like (Narrow? Collapsed? Surgically modified?) this determines coupling
  4. Dexterity of patient: Insertion/Removal, handling of batteries, handling and use of cleaning tools, etc.

Q

What are 10 referral guidelines for medical clearance?

A
  1. Visible congenital or traumatic deformity of the ear.
  2. Growths on pinna, or unusual growths in canal (exostosis).
  3. History of active drainage from the ear within the previous 90 days (odour from drainage may indicate infection)
  4. History of sudden or rapidly progressing hearing loss within the previous 90 days.
  5. Acute or chronic dizziness.
  6. Unilateral hearing loss of sudden or recent onset within the previous 90 days.
  7. Audiometric air-bone gap equal to or greater than 15 dB at 500 Hz, 1000 Hz, and 2000 Hz.

Q

Why is medical Clearance Important?

A
  • Suspicions of retro-cochlear, and middle ear issues must be addressed by ENT prior to fitting aids
  • Active, acute medical concerns must be addressed
  • Referral to ENT through family physician, ideally have medical clearance in writing prior to proceeding with hearing aids

Q

What are the 5 components of assessment?

A
  1. Interviewing the patient- where is help needed?
  2. Client-Oriented Scale of Improvement (COSI)

  4. Involving communication partners
  5. Understanding motivation— without it, success of intervention can be compromised

Q

How can hearing loss present in clinic?

A

What do patients tell us (or what do they not tell us)?
- “I can hear, I just can’t understand what people are saying”
- “Everyone is mumbling”
- Difficulty following conversations (dependant on environment)
- Frustration (may be from both patients or those close to them)
- Avoidance strategies, negative social impacts
- Admitting to feigning understanding conversation— “smile and nod”

Q

What is a common model used for counselling and supporting behavioural changes

A

Transtheoretical Model (TTM) of Health Behavioural Change

17
Q

What are the 4 components of the TTM model?

A
  • Pre-contemplation
  • Contemplation/Preparation
  • Action
  • Maintenance
18
Q

Explain the pre-contemplation phase

A
  • Not ready
  • Patient is unaware they have any problem with hearing
  • No intention of taking action unaware that hearing loss problematic
19
Q

Explain the contemplation/preparation phase

A
  • Getting ready
  • Recognition that hearing loss may be problematic, evaluate the pros and cons of seeking help, may ask questions about rehabilitation processes
  • Contemplation: beginning stages of awareness, they have a desire to fix this but may not know how
  • Preparation: ontention to take action
20
Q

Explain the action phase

A
  • Moving forward
  • Modifying behaviour, using therapy, acquiring new “healthy” behaviours, open to assistance, and counselling
  • Made a change in a positive direction
21
Q

Explain the maintenance phase

A

Maintain that action in a positive way

22
Q

What are 4 things someone may do in the pre-contemplation stage?

A
  • Play down the impact of their hearing difficulties on their everyday life
  • Display low concern for their hearing difficulties
  • Provide self-initiated examples of situations where they can hear well
  • Attribute blame for hearing difficulties to others (e.g. family members mumbling, or speaking softly), or situational factors (e.g. background noise)
23
Q

What are the Quick Six?

A

Getting a sense of patient difficulty through open-ended questions

  1. “Tell me what brought you into the office”
  2. “How long have you been noticing difficulty with communication?”
  3. “Do other people notice you having difficulty with communication?”
  4. “Tell me about the areas you are having difficulty with communication”
  5. “Would you be willing to accept help or assistance with the difficulties you are having”
  6. “ On a scale of 1 through 10, with 1 being ‘I don’t need help’, and 10 being ‘I need help right away’, how would you rate your ability to communicate?”
24
Q

Explain the self-perceived HL study (Palmer et al, 2009)

A
  • 848 hearing-impaired adults in the age range from 18 to 95 years were studied and asked:
  • “On a scale of 1 to 10, 1 being the worst, and 10 being the best, how would you rate your overall hearing ability”
  • More than 75% of patients who report a score between 1 and 5 will pursue amplification
  • Patients who rate there hearing between 8-10 will not likely pursue amplification
25
Q

How do we delicately manage reaction to hearing loss?

A
  • Recognition that often times, patients need time to digest the information we have given them
  • Patient-centric care in counselling means supporting patients in allowing them time, ask questions, and give space
26
Q

Explain the hearing handicap inventories

A
  • Self-assessment scale related to pre-fitting considerations
  • 25 points on the standard, 10 points on screening version
  • Version for Adult (under the age of 65) and Senior (over the age of 65)**emphasis on whether individual is employed.
  • Scale assess self-perceived handicap of hearing loss, with a focus of the emotional and social aspects of living with hearing loss
  • Score of each items are added for a final total: higher score= greater perceived handicap
27
Q

The HHIs aim to quantify to handicap with ____
and ____ considerations

A

Social, emotional

28
Q

What is the HHIA?

A

Hearing handicap inventory - adults

29
Q

What is the HHIE

A

Hearing handicap inventory - elderly

30
Q

Explain the COSI

A
  • The COSI is a frequently used outcome measure that evaluates pre-fitting needs, and post-fitting outcomes of amplification
  • Patient’s identify concerns that are relevant to them, and their unique situations
  • The goal of the COSI is to have patient’s target 5 listening situations, in which they would like to see improvement in their hearing with the use of amplification
31
Q

When is the COSI administered?

A

The COSI is a subjective outcome measure that is administered by the clinician when a patient proceeds with amplification

32
Q

Explain the two phases of the COSI

A
  • 1st: Identify listening situations that the patient would like to experience improvement in (rated by importance)
  • 2nd: Rate the change in those performance indicators after fitting (and some experience), and a final listening ability
33
Q

COSI - the benefits of amplification are assessed in what 2 different ways?

A
  • Degree of Change: Improvement provided by the hearing aids is rated as better or worse in a continuum
  • Final Hearing Ability: An absolute measure of communication ability (percentage of ability to hear in identified situations.
34
Q

What are 8 factors associated with amplification success?

A
  • Most “configurations” of hearing loss/partial loss can potentially be helped by amplification
  • Conductive vs. Sensorineural losses
  • Degree of hearing loss and word recognition ability
  • Appropriate electroacoustical parameters (i.e: is the gain appropriate for soft, medium, loud inputs?)
  • Physically comfortable fit
  • Appropriate level of technology for patient needs
  • Patient expectations
  • Patient motivation, and the acceptance of hearing loss
35
Q

What side will do good with amplification?

A
  • The audiogram on the left is going to do very well with amplification
  • The audiogram on the right may struggle more with amplification
36
Q

What is the CROS used for?

A
  • Contralateral Routing Of Signals
  • For single-sided deafness (SSD)
37
Q

What is a CROS device over coming?

A
  • The head shadow effect
  • Frequency-specific decrease in SPL occurs when sound is presented to the contralateral side of the skull
  • Greatest decrease occurs at the high frequencies (particularly above 1500 Hz!) What speech information is therefore compromised?
