Audiological screening is a pass fail procedure to.. (3 reasons)
|
1. prevent or detect early auditory impairment, disorder and disability
2. to i.d. individuals who require further audiological assessment and/or treatment 3. referral for professional services |
|
|
What are the 2 different approaches to screening?
|
1. medical model
2. educational model |
|
|
Which screening approach does this define..."focus is broader, identification, screening, tracking, referral, follow up, advocacy"
|
educational
|
|
|
Which screening approach does this define..."condition for which an individual is screened should lend itself to binary outcome, either pass/fail"
|
medical
|
|
|
2 concepts important to screening are:
|
sensitivity and specificity
|
|
|
What does sensitivity mean?
|
how effective procedure is in identifying a disorder
|
|
|
What does specificity mean?
|
how effective procedure is in passing individuals who do not have disorder
|
|
|
What is a negative false positive result?
|
when a person fails even when they can pass
|
|
|
What is a false negative result?
|
pass screening with disorder
|
|
|
What is a valid measure?
|
when the instrument measures what it is supposed to measure
|
|
|
What is a reliable measure?
|
when the measure is consistent across different situations
|
|
|
What are two decisions to make when deciding on the pass/fail criteria?
|
1. checking the screening level and making sure it is not too high or too low
2. using specific frequencies |
|
|
What are three factors that are influenced if a screening level that is to high or low ?
|
referral rate, specificity, sensitivity
|
|
|
Which frequencies does ASHA emphasize to use during screenings?
|
middle to high frequencies
|
|
|
What kind of equipment would you use for an infant during screening?
|
otoacoustic emissions or auditory brainstem responses
|
|
|
Are screenings done only to identify hearing loss?
|
No. they are also done to identify outer and/or middle ear disease.
|
|
|
Which population would screening for outer and/or middle ear disease be the most important?
|
preschool children
|
|
|
What type of equipment is calibration the most important for?
|
portable equipment
|
|
|
How often should you calibrate?
|
at least once a year
|
|
|
When can subjective calibration be done?
|
immediately prior to a screening by the audiologist
|
|
|
Are screenings done only to identify hearing loss?
|
No. they are also done to identify outer and/or middle ear disease.
|
|
|
Which population would screening for outer and/or middle ear disease be the most important?
|
preschool children
|
|
|
What type of equipment is calibration the most important for?
|
portable equipment
|
|
|
How often should you calibrate?
|
at least once a year
|
|
|
When can subjective calibration be done?
|
immediately prior to a screening by the audiologist
|
|
|
What are 6 things you check for during subjective calibration?
|
tone audible, check L and R ears, unwanted sounds, in and decrease audible in tone, changes in frequency, linear fashion or in jumps of changes in frequency and intensity
|
|
|
Would you use an audiogram to interpret results from a hearing screen?
|
No. It is better to create your own form. You do not use an audiogram because you are not measuring thresholds.
|
|
|
What are two reasons to keep in mind when avoiding overinterpretation of findings, such as, claiming a child has normal hearing?
|
1. hearing is more than just perception of tones but also involves recognition and reception of speech stimuli
2. screening only represents that point in time |
|
|
What are 6 components(steps) significant to the screening procedure?
|
1. non diagnostic otoscopy
2. instructions and ear phone placement 3. assure conditioning 4. group vs individual instructions 5.administering the screening 6. making recommendations |
|
|
What is the 1-3-6 rule regarding the screening protocol for infants?
|
screen by 1 month, identify hearing loss by 3 months, intervention by 6 months
|
