Abstract Objective To evaluate the rate of loss to follow-up in a cochlear implant program from the public health system in Southern Brazil as well as the characteristics of hearing loss, sociodemographic, sociocultural and the development of oral language in children with prelingual deafness. Methods Retrospective cohort study with children who underwent CI surgery between 2010 and 2020. Data was collected through of interviews and review of medical records. The language development assessment was performed using the MUSS, MAIS and IT-MAIS scales. For the classification of language development, we used as parameters the values (mean ± SD) found in a previous national study. From those values, the Z-score for each patient at each hearing age (time of experience with the cochlear implant) was calculated. Results Of the 225 children implanted between 2010-2020, 129 were included in this study. The rate of loss to follow-up in the program was 42.6%. The mean age at first surgery was 40.5 (±16.9) months, with 77.5% of patients having received a unilateral implant. Language results below the expected for hearing age (<Z-score-1) for the MAIS score were found in 59.7% of the sample, while for the MUSS score the proportion was 62%. Conclusions Most patients had an elevated mean age at cochlear implantation and there was a high rate of loss to follow-up and low attendance to speech and programming sessions. An overall poor language performance was found for this pediatric cochlear implant program from the public health system in Southern Brazil.

RESUMO Objetivo: avaliar o programa de triagem auditiva neonatal universal por meio de indicadores de qualidade. Métodos: foram analisados os registros de recém-nascidos que realizaram triagem auditiva neonatal em 2018, comparando-se os dados aos cinco primeiros indicadores de qualidade definidos pela diretriz nacional de atenção à triagem auditiva neonatal: 1°) índice de cobertura de triagem (≥95%); 2°) idade em meses na realização da triagem (até o 1° mês de vida); 3°) índice de encaminhados para diagnóstico (2% a 4%); 4°) índice de comparecimento ao diagnóstico (≥90%) e 5°) idade na conclusão do diagnóstico (até o 3° mês de vida). Os dados foram analisados de forma estatística quantitativa descritiva. Resultados: indicadores de cobertura; idade na realização da triagem e número de encaminhamentos para diagnóstico ficaram dentro do estabelecido pela diretriz nacional. Índice de comparecimento ao diagnóstico ficou abaixo do esperado e a idade na conclusão do diagnóstico foi registrada para 70% dos casos. Conclusão: o uso de indicadores de qualidade forneceu dados importantes sobre a efetividade do programa de triagem auditiva neonatal, assim como identificou oportunidades de melhoria no serviço, as quais podem contribuir na identificação precoce da deficiência auditiva.

ABSTRACT Purpose: to assess the universal neonatal hearing screening program using quality indicators. Methods: the records of newborns who were submitted to the neonatal hearing screening in 2018 were analyzed, comparing the data with the first five quality indicators established by the national guideline for neonatal hearing screening attention: 1) rate of screening coverage (≥95%); 2) age at the screening in months (up to the first month of life); 3) rate of referrals for diagnosis (2% to 4%); 4) rate of attendance to diagnostic examination (≥90%); 5) age at confirmed diagnosis (up to the third month of life). The data were submitted to quantitative and descriptive statistical analysis. Results: the rate of coverage, age at screening, and the number of referrals for diagnosis met the indicators established by the national guideline. The rate of attendance to diagnostic examination fell short of the expected, and the age at confirmed diagnosis was verified in 70% of the cases. Conclusion: using the quality indicators furnished important data on the effectiveness of the neonatal hearing screening program and identified opportunities to improve the service, which can help identify hearing loss, early.

Abstract Introduction Studies using the Brainstem Auditory Evoked Potential with speech stimulus are increasing in Brazil, and there are divergences between the methodologies used for testing. Objectives To analyze the parameters used in the study of the Brainstem Auditory Evoked Potentials with speech stimulus. Data Synthesis The survey was performed using electronic databases. The search strategy was as follows: “Evoked potentials, auditory” OR “Brain stem” OR “Evoked potentials, auditory, brain stem” AND “Speech.” The survey was performed from June to July of 2016. The criteria used for including articles in this study were: being written in Portuguese, English or Spanish; presenting the description of the testing parameters and the description of the sample. In the databases selected, 2,384 articles were found, and 43 articles met all of the inclusion criteria. The predominance of the following parameters was observed to achieve the potential during study: stimulation with the syllable /da/; monaural presentation with greater use of the right ear; intensity of 80 dB SPL; vertical placement of electrodes; use of in-ear headphones; patient seated, distracted in awake state; alternating polarity; use of speech synthesizer software for the elaboration of stimuli; presentation rate of 10.9/s; and sampling rate of 20 kHz. Conclusions The theme addressed in this systematic review is relatively recent. However, the results are significant enough to encourage the use of the procedure in clinical practice and advise clinicians about the most used procedures in each parameter.
