Screening

Finding

loss of hearing sensitivity and acuity from mild to profound, unilateral or bilateral

Tested By

automated auditory brainstem response testing (ABR or AABR), sensitivity=100%, specificity=99.7% [Hall: 2004]; or otoacoustic emission testing (OAE), sensitivity of 76.9%, specificity of 90% [Llanes: 2004].

AABR measurements reflect the function of the entire auditory system, including the peripheral auditory system, the eighth nerve, and the brainstem auditory pathway. OAEs reflect the status of the peripheral system extending to the cochlear outer hair cells. In some centers, OAE testing is performed first with secondary AABR testing if the OAE is failed.

ICD-9

389, Hearing loss

389 is a non-specific code reflecting the clinical finding that does not specify a diagnosis. The diagnosis and code are determined by the cause of the hearing loss. See Hearing Impairment ICD-9 (PDF Document 58 KB) for details.

Overview

  • Conductive hearing disorders involve outer and middle ear structures (congenital anomalies, otitis media, etc.).
  • Sensory hearing disorders involve the cochlea and inner ear structures (maternal and acquired infections).
  • Neural hearing disorders result from problems involving the auditory nervous system (neoplasm and hypoxia, auditory neuropathy/dyssynchrony).

The Joint Committee on Infant Hearing (JCIH) endorses early hearing detection and intervention for infants with hearing loss. The goal is to maximize linguistic competence and literacy development for children who are deaf or hard of hearing. Without early detection and opportunities for language development, children with hearing loss will fall behind their peers in communication, cognition, reading, and social-emotional development. [Joint: 2007]

All infants should have newborn hearing screening prior to one month of age. If immediate newborn screening is not possible (e.g., home birth, birth in a center not offering screening, infant discharge before testing is completed), referral should be made to a pediatric audiologist who can perform screening within the first month of life.

Repeat newborn hearing screening is recommended if an infant is readmitted to the hospital for sepsis, meningitis, or hyperbilirubinemia requiring exchange transfusion.

Infants admitted to the NICU for 5 days or more are at increased risk for auditory neuropathy and should have and AABR performed as part of their screening; in these patients an OAE alone is insufficient.

Prevalence

Incidence of neonatal hearing loss in the United States is 1.1/1000 and varies by state from 0.22 to 3.61/1000 [Mehra: 2009]; (Utah 2.2 - 2.4/1000)

Inheritance

More than half of childhood hearing loss is genetic. Approximately 70% of genetic sensorineural hearing loss (SNHL) is nonsyndromic (not associated with other known anomalies or abnormalities).
  • 77% recessive
  • 22% dominant
  • 1% X-linked
More than 400 genes have been identified that are associated with hearing loss.

Clinical Characteristics

With treatment starting by six months of age, children have improved language and speech skills, comparable with peers. Without treatment, children have impaired ability to communicate; decreased speech and language development; and problems with emotional and social development.

Follow-up on positive screening test

Refer to an audiologist for repeat testing within one month and, if still positive, additional testing to determine the type of hearing loss and possible causes.

Primary care management

Upon notification of the + screen

If the diagnosis is confirmed

  • Educate the family regarding the need for:
    • speech and language therapy
    • hearing amplification to overcome hearing loss
    • evaluation by an ophthalmologist
    • availability of early intervention services
  • Provide information about communication options and hearing technologies
  • Evaluate for possibly-linked medical conditions, such as heart arrhythmias, vision problems, and kidney problems.

Specialty Care Management

Initial consultation and ongoing management with a pediatric audiologist during the newborn period. Consultation with an otolaryngologist if anatomical abnormalities exist or for consideration of cochlear implantation. Consultation and ongoing management with audiology; early intervention; speech and language therapy; and the school system during childhood.
