Fifteen years of early hearing screening in Flanders: impact on language and education

OBJECTIVES: To assess the impact of fifteen years of universal neonatal hearing screening in Flanders on language development and the educational setting. METHODOLOGY: An analysis of the database of Kind en Gezin from 1997 to 2012 and a long-term evaluation of the children referred to our centre after failed neonatal hearing screening. The CELF and PPVT language tests were performed. RESULTS: Between 1997 and August 2012, bilateral hearing loss was confirmed in 2393 children in Flanders, of whom 11.4% were referred to our tertiary centre. The educational setting and language development of 84 children older than 5 years was evaluated and 54% of them had additional disabilities. Of the children without additional disabilities, 84% attended mainstream schools; 42% of children with additional disabilities entered mainstream education with additional support. There was a significant correlation between the number of additional disabilities and the education level (p < 0.001) and between the degree of hearing loss and educational placement (p < 0.001). Data on language development were available for 76% of the children and a significant correlation could be demonstrated only between the results of the PPVT language and the number of additional handicaps (p < 0.008). CONCLUSIONS: The majority of children receiving early treatment after neonatal hearing screening enter mainstream education. The number of additional disabilities has a significant effect on education level and language development.status: publishe

Detection of Perinatal Cytomegalovirus Infection and Sensorineural Hearing Loss in Belgian Infants by Measurement of Automated Auditory Brainstem Response▿

Since auditory disability causes serious problems in the development of speech and in the total development of a child, it is crucial to diagnose possible hearing impairment as soon as possible after birth. This study evaluates the neonatal hearing screening program in Flanders, Belgium. The auditory ability of 118,438 babies was tested using the automated auditory brainstem response. We selected 194 babies with indicative hearing impairment and 332 matched controls to investigate the association between the presence of human cytomegalovirus (HCMV) in urine samples and sensorineural hearing loss and to analyze the sensibility and specificity of a cell culture assay and a quantitative PCR detection method. Our results indicate that significantly more babies with confirmed hearing impairment were HCMV positive after birth. Further, based on the results of our study, babies with HCMV viral loads above 4.5 log copies/ml urine seem to be 1.4 times more likely to have confirmed hearing impairment. Our follow-up study suggests that the hearing impairment of children infected with HCMV after birth is less likely to improve than that of HCMV-negative infants. Our results confirm that the presence of HCMV before or shortly after birth influences the outcome of hearing impairment

Pediatric cochlear implantation: a qualitative study of the parental decision-making process in Flanders, Belgium

Factors contributing to parents' decision when they choose between cochlear implantation (CI) and traditional hearing aids for their child were examined. The subjects were children with severe/profound hearing loss, born 1999-2001, registered in the universal neonatal hearing screening program in the Flanders region of Belgium. Qualitative data collected retrospectively from parents were subjected to thematic content analysis. In their responses to professional advice, parents were segmented into 3 groups: (a) those whose primary considerations were the importance of oral language development and the relative potential of CI and traditional hearing aids; (b) those for whom alternative factors (e.g., medical risks, ethical issues) were paramount, even in the face of professional advocacy of CI; (c) those who followed professional advice against CI. The researchers conclude that care professionals should be sensitive to the impact of their advice and other factors in parental decision making
