“…The unaided SII quantifies the proportion of speech information that is audible to the listener in a given setting. An SII of 0.0 (0%) suggests that no speech information is audible, and an SII of 1.0 (100%) indicates that all speech information in a given setting is audible [ 41 – 45 ]. As SII is often reported as a percentage in clinical applications, we have chosen to report percentages for our findings.…”

BackgroundWolfram syndrome (WFS) is a rare autosomal recessive disease with clinical manifestations of diabetes mellitus (DM), diabetes insipidus (DI), optic nerve atrophy (OA) and sensorineural hearing loss (SNHL). Although SNHL is a key symptom of WFS, there is limited information on its natural history using standardized measures. Such information is important for clinical care and determining its use as an outcome measure in clinical trials.MethodsStandardized audiologic measures, including pure-tone testing, tympanometry, speech perception, and the unaided Speech Intelligibility Index (SII) were assessed in patients with confirmed WFS annually. Mixed model analyses were used to examine main effects of age, time or interactions for pure tone average (PTA), high frequency average (HFA) and SII.ResultsForty WFS patients were evaluated between 1 and 6 times. Mean age at initial enrollment was 13.5 years (SD = 5.6). Patients were classified as having normal hearing (n = 10), mild-to-severe (n = 24) or profound SNHL (n = 6). Mean age of diagnosis for SNHL was 8.3 years (SD = 5.1) with 75% prevalence. HFA worsened over time for both ears, and SII worsened over time in the worse ear, with greater decline in both measures in younger patients. Average estimated change over 1 year for all measures was in the subclinical range and power analyses suggest that 100 patients would be needed per group (treatment vs. placebo) to detect a 60% reduction in annual change of HFA over 3 years. If trials focused on just those patients with SNHL, power estimates suggest 55 patients per group would be sufficient.ConclusionsMost patients had a slow progressive SNHL emerging in late childhood. Change over time with standard audiologic tests (HFA, SII) was small and would not be detectable for at least 2 years in an individual. Relatively large sample sizes would be necessary to detect significant impact on hearing progression in a clinical trial. Hearing function should be monitored clinically in WFS to provide appropriate intervention. Because SNHL can occur very early in WFS, audiologists and otolaryngologists should be aware of and refer for later emerging symptoms.Electronic supplementary materialThe online version of this article (10.1186/s13023-018-0852-0) contains supplementary material, which is available to authorized users.

“…Whereas the concept of using the aided SII for cochlear implant candidacy has been suggested (Leal, Marriage, & Vickers, 2016), the implementation of the unaided SII as a candidacy criterion for hearing aids is limited by the current lack of evidence about the degree of hearing loss where delays in speech and language begin to emerge across the range of degrees of hearing loss. The goal of this study was Figure 1.…”

Purpose Because of uncertainty about the level of hearing where hearing aids should be provided to children, the goal of the current study was to develop audibility-based hearing aid candidacy criteria based on the relationship between unaided hearing and language outcomes in a group of children with hearing loss who did not wear hearing aids. Method Unaided hearing and language outcomes were examined for 52 children with mild-to-severe hearing losses. A group of 52 children with typical hearing matched for age, nonverbal intelligence, and socioeconomic status was included as a comparison group representing the range of optimal language outcomes. Two audibility-based criteria were considered: (a) the level of unaided hearing where unaided children with hearing loss fell below the median for children with typical hearing and (b) the level of unaided hearing where the slope of language outcomes changed significantly based on an iterative, piecewise regression modeling approach. Results The level of unaided audibility for children with hearing loss that was associated with differences in language development from children with typical hearing or based on the modeling approach varied across outcomes and criteria but converged at an unaided speech intelligibility index of 80. Conclusions Children with hearing loss who have unaided speech intelligibility index values less than 80 may be at risk for delays in language development without hearing aids. The unaided speech intelligibility index potentially could be used as a clinical criterion for hearing aid fitting candidacy for children with hearing loss.

“…These guidelines, established in late 2019, suggest that a child who meets 1 of these criteria in at least 1 ear should be referred for evaluation. They include a standard pure tone average (PTA; average at 500, 1000, and 2000 Hz) of 65 dB HL or greater, 22 an aided speech intelligibility index of 0.65 or poorer, [23][24][25][26][27] or an aided word recognition score of 60% or poorer. 17,22 To establish benchmarks for the referral rate of children meeting these criteria, we identified children seen in the past 5 years for diagnostic and hearing aid care across our state-wide healthcare entity who met these newly established criteria.…”

Sound Opportunities: Factors That Impact Referral for Pediatric Cochlear Implant Evaluation

Objectives/Hypothesis: To identify barriers to and opportunities for referral among children who could be considered for cochlear implantation.Study Design: Retrospective review.Methods: Audiological and medical records were reviewed on all children who had diagnostic or hearing aid care through a statewide healthcare system over 5-year span to identify children who met newly established clinical cochlear implant (CI) referral criteria. Data were collected for 869 potential CI candidates regarding demographic, socio-economic, audiological, medical, and family factors that may influence referral. A binomial logistic regression was completed to investigate the potential contributions of these predictors toward referral for a CI evaluation.Results: Children who met traditional candidacy criteria of severe-to-profound bilateral hearing loss were referred at very high rates, while nontraditional candidates were referred less frequently. Factors influencing referral included race, age, insurance source, hearing thresholds, audiologist, physician, and family request.Conclusions: Results suggest that bilateral traditional candidates are being referred at high percentages; however, current practices and trends in pediatric cochlear implantation should be shared with families and providers to increase referral rates for nontraditional candidates.
