Early assessment of communicative competence in children with hearing loss using the Child-Caregiver Communication Assessment through Rebesco's Evaluation (CC-CARE) method.

PURPOSE: This work presents a new frame-by-frame video analysis method called Child-Caregiver Communication Assessment through Rebesco's Evaluation (CC-CARE), developed in the context of pediatric hearing loss as a rehabilitation tool for assessing children's early communication skills. CC-CARE stems from the commonly used Tait video analysis and extends it by including a new set of parameters aimed at disentangling between hearing-dependent and hearing-independent aspects of communication. METHOD: In this paper, we collected video samples of child-caregiver interactions in a group of 65 normal-hearing children and a group of 165 hearing-impaired children. For each group, we present the CC-CARE method and describe the parameters, their score distributions, correlations and we estimate the adherence of the CC-CARE scores with children's developmental trajectory. Moreover, we compare the results of CC-CARE scores between the two groups having had different development of the auditory system. Finally, a fully-data driven approach was employed to assess the consistency of the communicative efficacy index (CEI), a score aiming to capture a global result of the CC-CARE procedure. RESULTS: Correlations among parameter scores were found in each within-group analysis, revealing CC-CARE's internal consistency in measuring associated but nonoverlapping communication dimensions. For both groups, CC-CARE scores were associated with participants' age. Differences between scores emerged for a between-group analysis, indicating CC-CARE sensitivity to extract communication differences as a function of the hearing status. For both groups, the data analysis revealed that the CEI captures large variance portions across all parameter scores of the CC-CARE method. CONCLUSIONS: Results provide the first evidence that the CC-CARE video analysis method could be a reliable tool capable of highlighting the cascading effects of hearing impairment on children's preverbal communicative efficacy. The CC-CARE method aims to support early rehabilitation of hearing loss by describing a child's communicative efficacy.

Assessment of Communication Abilities in Four Children with Early Bilateral CIs in Clinical and Home Environments with LENA System: A Case Report.

Children's language acquisition is underpinned by the quantity and quality of linguistic stimulation. Early diagnosis and cochlear implantation (CI), along with a family-centered intervention, are regarded as critical factors in providing appropriate language stimulation and thus supporting successful language outcomes in children with sensory neural hearing loss (SNHL). Considering the lack of tools to assess early language skills and open issues regarding the early predictors of CI outcomes, our goal was to evaluate the potential usability of the Language ENvironment Analysis (LENA) system as an early assessment and/or predictive tool. Clinical video recordings, LENA home recordings, and vocabulary scores were used to assess the progression of communication abilities of four children with CIs (6-35 m.o.). The data revealed a positive correlation between the estimated mean length of utterance (EMLU), vocal conversational turns (CT) in clinical video recordings, and receptive vocabulary, as well as the CT count in LENA being a significant predictor of productive vocabulary. These findings lead us to conclude that the LENA system has the potential to be used as an additional (tele-)measure in the early assessment of communication abilities of children with CI, as well as as a tool in the research of early predictors of CI outcomes.

Reliability of parental assessment of auditory skills in young children: a cross-sectional study in Italian language.

OBJECTIVE: Hearing impairments (HIs) that progress or have later onset may have specific effects on language and cognitive development, but are difficult to suspect during routine primary care visits. Family concern regarding hearing is thought to represent an important risk factor requiring audiological examination. Yet it is not clear how successful parents are in recognising the consequences or specific suspect elements of HI in young children. The aim of this study is to verify whether parents of at-risk children recognise the presence of HI through a parental questionnaire that draws attention to auditory skills development and compares them with language and communication skills. DESIGN: Observational study. SETTING: From 2013 to 2019, parents were administered the Questionnaire on Hearing and Communication Abilities before audiological evaluation of their children at a secondary care institute. PARTICIPANTS: 309 Italian children (1-36 months old) at risk of HI. PRIMARY AND SECONDARY OUTCOME MEASURES: Questionnaire sensitivity in predicting the presence and type of HI. RESULTS: Parents report a decrease in auditory skills for children with sensorineural HI (Χ2(2)=14.4, p=0.003), with an increased concern expressed in 59% compared with 24% in normally hearing children. Both auditory (r=-0.18, p=0.002) and comprehension (r=-0.13, p=0.057) skills weakly but negatively correlated with a diagnosis of HI. On discriminant analysis, the positive predictive value of the questionnaire was 0.78, but with low sensitivity (0.39). CONCLUSIONS: Parents of children with a verified risk of HI have some capacity to recognise non-typical auditory behaviour. Thus, it is important to assess parental concerns during primary care health visits, and a targeted questionnaire on auditory abilities can complement existing screening procedures. However, given the low sensitivity of the questionnaire, we conclude that for a reliable detection of HIs that progress or have later onset an objective screening tool is always required.

Who misses the newborn hearing screening? Five years' experience in Friuli-Venezia Giulia Region (Italy).

INTRODUCTION: Permanent hearing impairment is the most common sensory disorder in newborns. The Universal Newborn Hearing Screening (UNHS) is widely adopted as a cost-effective procedure to achieve early identification and treatment of congenital hearing impairment, with the final goal of an improved linguistic and cognitive outcome for hearing impaired children. The Italian Ministry of Health has recently comprised UNHS in the Essential Level of Health Assistance. Nevertheless, programs still vary both across and within Italian Regions in terms of coverage, testing, referral and tracking protocols. In Friuli-Venezia Giulia region the program for the early identification of newborn and childhood hearing impairment is operative since 2012. In order to minimize the lost to follow-up cases, UNHS and childhood hearing surveillance activities have been organized in close collaboration among birth centres, paediatric audiology services, territorial Family Paediatricians and the sole regional centre for paediatric hearing loss management. MATERIAL AND METHODS: We performed a five years' retrospective analysis of the UNHS experience in Friuli-Venezia Giulia comparing the UNHS activity of year 2013 and year 2017. The focus of the study concerns the "missing" cases. Three different typologies of "miss" cases ("documentation-miss", "access-miss" and "pathway-miss") have been defined in correspondence with main reasons for their occurrence. RESULTS: Births in Friuli-Venezia Giulia were 9465 and 8432, respectively in 2013 and 2017. International quality indicators improved with a gain of efficiency in 5 years' experience. However, "missing" cases were 486 in 2013 and 321 in 2017, mainly due to the lack of an efficient documentation system. CONCLUSION: UNHS programs have proven to be valuable and cost-effective in Friuli-Venezia Giulia and other Italian regions. New resources and efforts are required to achieve a complete standardization and informatisation of the UNHS data to avoid documentation gaps. A possible strategy would point to the opportunity to unify data management systems for all the ongoing newborn screening programs (metabolic, hearing and visual), linking the integrated IT system with the regional repository of current datasets.

Hearing assessment in high-risk congenital diaphragmatic hernia survivors.

OBJECTIVE: To report results of audiometric evaluations in high-risk congenital diaphragmatic hernia survivors and their exposure to audiological risk factors (mechanical ventilation, high frequency oscillation, aminoglycoside therapy and neuromuscular blocking agents). DESIGN: All newborns with high-risk congenital diaphragmatic hernia born between January 2003 and June 2009 were treated consecutively at the Neonatal Intensive Care Unit, Pediatric Hospital, University of Padova. Thirty-two survived and 26 of them underwent formal audiological evaluation (tonal and speech audiometry, otoacoustic emission, and immitance measurements) and follow up. RESULTS: Twenty-one children had normal hearing; 4 had conductive hearing loss, which was successfully treated; and 1 had severe sensorineural hearing loss and suffers from Turner syndrome. CONCLUSIONS: Our series revealed a lower prevalence of sensorineural hearing loss in high-risk congenital diaphragmatic hernia survivors than in other studies, suggesting that the association between hearing loss and congenital diaphragmatic hernia has yet to be accurately defined and fully elucidated.
