Question | Answer |
Goal of Hearing Screening | accurately and efficiently identify hearing impairment by maximizing the number of correct identifications (sensitivity) while minimizing the false positives (specificity) |
number of children born with congenital, significant, permanent, bilateral hearing loss | 3 in 1000 infants |
number of children that will acquire deafness in early childhood | 3 in 1000 children |
number of infants born daily in the US with permanent hearing loss | 33 infants |
estimated number of school days missed yearly due to otitis media (middle ear infection) | 5 million days |
percentage of children who receive hearing screening at school and fail because they cannot hear within normal limits | 10 - 15 % of children |
Goal for early intervention for hearing loss | every baby tested by 1 month, diagnosed by 3 months, intervened by 6 months |
neonate | 0 - 28 days |
infant | birth - 3 years |
preschool | 3 - 5 years |
school-age | 5 years - high school |
EHDI | Early Hearing Detection and Intervention |
Early Hearing Detection and Intervention - 3 components | 1. birth admission screen, 2. follow-up assessment, 3. intervention |
Early Hearing Detection and Intervention - desired outcome | intervention before 6 months of age, infants who meet defined criteria for erferral should receive follow-up evaluation by 3 months |
Infant screening | high risk indicators, behavioral testing (BOA), physiological testing (ABR, OAE) |
