“…The PB-k lists are composed of 25 words found in average vocabulary of a kindergarten-aged child and is scored as ‘percent correct’ [35–37]. Pediatric CI recipients may continue improving in their speech perception performance for longer than 5 years after implantation [38]. However, for the purposes of this study, we used the PB-k scores that were part of a stable of performance as indicated by PB-k scores within 10 points of each other during two consecutive testing sessions, collected after at least 1 year of CI use.…”

OBJECTIVES To assess electrocochleography (ECochG) to tones as an instrument to account for CI speech perception outcomes in children with auditory neuropathy spectrum disorder (ANSD). MATERIALS & METHODS Children (<18 years) receiving CIs for ANSD (n=30) and non-ANSD (n=74) etiologies of hearing loss were evaluated with ECochG using tone bursts (0.25–4 kHz). The total response (TR) is the sum of spectral peaks of responses across frequencies. The compound action potential (CAP) and the auditory nerve neurophonic (ANN) in ECochG waveforms were used to estimate nerve activity and calculate nerve score. Performance on open-set monosyllabic word tests was the outcome measure. Standard statistical methods were applied. RESULTS On average, TR was larger in ANSD than in non-ANSD subjects. Most ANSD (73.3%) and non-ANSD (87.8%) subjects achieved open-set speech perception; TR accounted for 33% and 20% of variability in the outcomes, respectively. In the ANSD group, the PTA accounted for 69.3% of the variability, but there was no relationship with outcomes in the non-ANSD group. In both populations, nerve score was sensitive in identifying subjects at risk for not acquiring open-set speech perception, while the CAP and the ANN were more specific. CONCLUSION In both subject groups, the TRs correlated with outcomes but these measures were notably larger in the ANSD group. There was also strong correlation between PTA and speech perception outcome in ANSD group. In both subject populations, weaker evidence of neural activity was related to failure to achieve open-set speech perception.

“…Clear distinction was made in the statistical analysis of data between children with congenital/ early onset (pre-lingual) hearing loss and children with post-natal (sudden/progressive) onset hearing loss. This distinction is important when a heterogeneous caseload is considered, since it is expected that children with postlingual onset hearing loss will mostly perform well after cochlear implantation as a result of more mature auditory pathways and early foundations for speech and language [24,[67][68][69].…”

Objective: To identify and describe predictors of pediatric cochlear implantation outcomes in a South African population. Methods:A retrospective study of 301 pediatric CI recipients from five cochlear implant programs was conducted and cross-sectional outcome data were added at the time of data collection. Twenty potential prognostic factors were identified from the retrospective dataset, including biographical, cochlear implant (CI), family and risk factors. Multiple regression analyses was performed to identify predictor variables that influence outcomes in terms of auditory performance (CAP scores), speech production (SIR scores), communication mode and educational placement.Results: Although implanted children within this sample did not have equal opportunity to access a second implant, bilateral implantation was strongly predictive of better auditory performance and speech production scores, an oral mode of communication and mainstream education. NICU admittance/ prematurity were associated with poorer auditory performance and speech production scores, together with a higher probability for non-oral communication and non-mainstream education. The presence of one or more additional developmental 2 condition was predictive of poorer outcomes in terms of speech production and educational placement, while a delay between diagnosis and implantation of more than one year was also related to non-mainstream education. Ethnicities other than Caucasian were predictive of poorer auditory performance scores and a lower probability for mainstream education.Conclusion: An extensive range of prognostic indicators were identified for pediatric CI outcomes in South Africa. These predictive factors of better and poorer outcomes should guide pediatric CI services to promote optimal outcomes and assist professionals in providing evidence-based informational counselling.

“…Children (referred to as ‘patients’), may receive any brand of regulatory approved implantable hearing device including any type of cochlear, bone conduction, electroacoustic or other implantable hearing device. If required, the Cochlear P-IROS platform also permits the capture of data from patients implanted at age 10 years or above, to address the growing trend for intervention in older children with an acquired or progressive hearing loss [ 30 ]. Additional questionnaires appropriate for this age bracket have been included for completion by these individuals' proxies.…”

BackgroundCurrently, there is a paucity of data concerning the long-term outcomes, educational placement and quality of life of children implanted with hearing devices from large and representative samples of the population. To address this concern, a large, prospective, multicentre, multinational patient-outcomes registry for paediatric recipients of implantable hearing devices was developed. The benefits of this registry, its approach and methodology are described.Methods/DesignThe Cochlear™ Paediatric Implanted Recipient Observational Study (Cochlear P-IROS) is a prospective international patient-outcomes registry for children who are implanted in routine clinical practice with one or more hearing devices. The study aims to collect data on patient comorbidities, device use, auditory performance, quality of life and health-related utilities, across different types of implantable hearing devices from a range of manufacturers. Patients will be evaluated with a set of standardised and non-standardised questionnaires prior to initial device activation (baseline) and at six-monthly follow-up intervals up to 24 months and annually thereafter. The Cochlear P-IROS utilises a secure web interface to administer electronic case report forms to clinicians and families of implanted children. The web interface is currently available in five languages: English, Japanese, Korean, Mandarin and Russian. The interface also provides printable versions of the case report forms translated into 22 local languages for collection of data prior to entry online; additional languages may be added, as required. Participation in the Cochlear P-IROS registry is investigator-driven and voluntary. To date, the Cochlear P-IROS has recruited implant clinics across Australia, China, India, Indonesia, Turkey and Vietnam. The registry also aims to recruit multiple clinics in Cuba, Israel, Japan, Malaysia, Singapore, South Africa, South Korea and Russia.DiscussionThe use of a registry such as the Cochlear P-IROS will generate valuable data to support research interests of academics and clinicians around the globe. The data generated will be relevant for a wide range of stakeholders including regulators, payers, providers, policy makers, patients and their families, each with a different perspective for the acceptance and adoption of implantable hearing devices for the treatment of hearing loss.
