Prognostic validity of dichotic multiple frequencies auditory steady-state responses versus distortion product otoacoustic emissions in hearing screening of high risk neonates

Conclusions
ASSR with this special paradigm is a fairly desirable method for hearing screening of high-risk neonates. There is good concordance between ASSRs and DOPAEs results among high risk neonates referred for hearing screening. The sensitivity and specificity of this test is sufficient for hearing screening in high risk neonates. This test could be valuable for rapid confirmation of normal thresholds. As long as further research have not been conducted on ASSR, great caution should be made to interpret the results of ASSR as a hearing screening technique in young infants and also additional techniques such as the tone-evoked ABRs should be used to cross-check results. It’s still too soon to recommend ASSRs as a standalone electrophysiologic measure of hearing thresholds in infants.

Appropriate hearing screening in the pediatric patient with head trauma

Any child with head trauma and clinical or radiologic evidence of temporal bone fracture should have early hearing evaluation. Using the proposed algorithm to test children with head trauma and GCS ≤13 and/or LOC and age ❤ years or any type of skull fracture may help identify children with hearing loss in a more cost effective manner.

Comparison of two hearing screening programs in the same population: Oto-acoustic emissions (OAE) screening in newborns and behavioral screening when infants

Conclusions
Newborn hearing screening has the advantages of objectivity, early identification, and higher compliance. The major advantage of the later behavioral test is identification of later onset or progressive hearing impairment as well as auditory neuropathy spectrum disorder. Each screening test is testing different entities; hence they are complementary and not interchangeable or superfluous.

We recommend a comprehensive two-step hearing screening plan (newborn and later behavioral) with close cooperation between the health care providers involved.

Reversible auditory brainstem responses screening failures in high risk neonates

This work is aimed at assessing the frequency of occurrence of reversible auditory brainstem responses (ABR) abnormalities within a targeted hearing screening program for high risk (HR) newborns. The effect of age on screening is also evaluated and some important clinical issues are highlighted. The audiological records of 1,294 HR neonates were retrospectively reviewed. All children were tested for hearing loss using ABR within a 17-year period. Initial failures were re-examined 4–6 months later. The mean age of infants who scored “pass” and “refer” at initial test, as well as the referral rates were calculated and compared. One hundred and seventy-eight infants (13.8%) demonstrated abnormal recordings at initial screening. From those who were present on re-examination, 64.2% showed complete and 15% partial recovery. Reversible abnormalities have been detected not only for conductive threshold elevation but also for sensorineural losses. Remarkably, 50% of the cases with absent waveforms or ABR threshold ≥80 dBnHL demonstrated complete recovery to normal. Statistically, higher rates of abnormal results were inversely associated with the newborn’s age at initial testing. In conclusion, reversible ABR abnormalities are common among HR infants due to temporary auditory dysfunction, secondary to external and middle ear pathology or retarded central nervous system maturation. The observed high rates of transient ABR abnormalities give rise to some practical questions regarding the implementation time of hearing screening for HR infants. Moreover, given that central nervous system maturation changes may still be in progress, the definite decision for an early cochlear implantation in this pediatric subset should be made after obtaining reliable behavioral hearing tests.

Prevalence and Risk Factors of Hearing Impairment Among Primary-School Children in Shebin El-Kom District, Egypt

The prevalence of HI did not differ across settings and was more common than reported in children from developed countries. The screening results also suggest that professionals with limited audiology background can be trained to implement hearing screening programs in Egyptian schools.

The Hearing Scale Test for hearing screening of school-age children

Conventional PTS only gives a pass/fail result for each screened ear, lacks hearing status assessment, and lacks stratified test values to be recorded for follow-up. In contrast, the HST has stratified hearing scales for each screened ear, which reflects the current hearing status and provides test values that can be recorded for follow-up.

Screening for Hearing Loss in the Elderly Using Distortion Product Otoacoustic Emissions, Pure Tones, and a Self-Assessment Tool

Purpose: To determine whether distortion product otoacoustic emissions (DPOAEs) could be used as a hearing screening tool with elderly individuals living independently, and to compare the utility of different screening protocols: (a) 3 pure-tone screening protocols consisting of 30 dB HL at 1, 2, and 3 kHz; 40 dB HL at 1, 2, and 3 kHz; or 40 dB HL at 1 and 2 kHz; (b) the Hearing Handicap Inventory for the Elderly—Screening version (HHIE–S); (c) pure tones at 40 dB HL at 1 and 2 kHz plus the HHIE–S; and (d) DPOAEs.

Method: A total of 106 elderly individuals age 65–91 years were screened using the above protocols.

Results: Pass/fail results showed that most individuals failed at 30 dB HL, followed by DPOAEs, the 40-dB HL protocols, the HHIE–S alone, and the combined pure-tone/HHIE–S protocol. All screening results were associated except the HHIE–S and 30 dB HL and the HHIE–S and DPOAEs. A McNemar analysis revealed that the differences between the correlated pass/fail results were significant except for the HHIE–S and 40 dB at 1 and 2 kHz.

Conclusion: DPOAEs can be used to screen the elderly, with the advantage that individuals do not have to voluntarily respond to the test.

Hearing Assessment in Infants and Children: Recommendations Beyond Neonatal Screening

Congenital or acquired hearing loss in infants and children has been linked with lifelong deficits in speech and language acquisition, poor academic performance, personal-social maladjustments, and emotional difficulties. Identification of hearing loss through neonatal hearing screening, regular surveillance of developmental milestones, auditory skills, parental concerns, and middle-ear status and objective hearing screening of all infants and children at critical developmental stages can prevent or reduce many of these adverse consequences. This report promotes a proactive, consistent, and explicit process for the early identification of children with hearing loss in the medical home. An algorithm of the recommended approach has been developed to assist in the detection and documentation of, and intervention for, hearing loss.

A systematic review of pediatric sensorineural hearing loss in congenital syphilis

There have been no reports of children with confirmed congenital SNHL secondary to in utero syphilis infection. Newborns with positive syphilis serology should have hearing screening performed at birth and receive treatment with an appropriate course of penicillin therapy. Longitudinal hearing screening is recommended for all pediatric patients with congenital syphilis, as further studies documenting longitudinal audiometric data for patients previously treated either fully or partly for congenital syphilis are required.

Parents’ experiences in a locally initiated newborn hearing screening program

from the Canadian Journal of Speech-Language Pathology and Audiology

This exploratory qualitative study presents an in-depth look at the experiences of five parents whose children were diagnosed with a hearing loss through newborn hearing screening. The screening was implemented as part of a research project in four health regions in Alberta. The funding for this project covered only newborn hearing screening, with referral to diagnosis. Program restructuring that allowed seamless transitions from screening to diagnosis and intervention services could not be funded, so parents needed to access already existing support services and programs. The parents in this study shared their experiences pertaining to the screening and diagnostic process and their transition to intervention programs. The following three major themes emerged from the parents’ stories as they shared their perspectives: (a) experiencing and dealing with the screening and diagnosis, (b) interacting with professionals, and (c) coping and realizing additional areas of need. The findings of the study indicate that the parents experience significant challenges as they navigate the process. The stories of parents provide valuable insights into their own strengths and how screening services, professional interactions, and the process of empowering parents can be improved.

Hearing and balance screening and referrals for Medicare patients: a national survey of primary care physicians

from the Journal of the American Academy of Audiology

Hearing and balance problems are prevalent among the elderly. Primary care physicians (PCPs) are important pivotal points of entry for ensuring that patients receive needed audiology services. New Medicare beneficiaries are entitled to one-time preventative examinations including hearing/balance screenings. A 35-item questionnaire was developed to assess physicians’ participation in, knowledge about, and attitudes toward hearing/balance screenings and referrals for the elderly. The survey was mailed to 710 PCPs (19 undeliverable; 95 returned; response rate = 13.7%) in major metropolitan areas in the United States. Generally, these PCPs were not conducting hearing/balance screenings, aware of patient self-report screening questionnaires, or likely to screen in the future. They referred to audiologists and otolaryngologists mainly when patients complained of having hearing/balance difficulties, and they stated that these problems were important in the elderly and that the Medicare program was worthy of funding but that they had little time and were not reimbursed appropriately for screening. Therefore, PCPs could benefit from informational outreach campaigns on the prevalence of, negative HRQoL (health-related quality of life) effects from, and screening procedures for hearing/balance disorders in the elderly.
