ABSTRACT
BACKGROUND: The use of Auditory Steady-State Responses (ASSRs) for auditory screening in school-aged children, particularly in children who are difficult to test and children with disabilities, has not been explored yet. This pilot study investigated the use of ASSR for auditory screening in school-aged children. MATERIALS AND METHODS: A cross-sectional pilot study of 23 children aged 9 to 11 with normal-hearing thresholds and seven age-matched children with permanent moderate-to-profound bilateral hearing loss were examined. The tested carrier frequencies were 500, 1,000, 2,000, and 4,000 Hz, and the stimulus was modulated between 77 and 107 Hz. The ASSRs decreased according to the tested intensity levels of 50, 40, and 30 dB sound pressure level (SPL). Sensitivity and specificity were estimated from the responses of the children with normal hearing and those with hearing loss. RESULTS: For the children with normal hearing, the 2,000-Hz frequency was detected more often in both ears and at all intensity levels compared to the other frequencies. The 500- and 2,000-Hz frequencies resulted in different response patterns in both ears. The time until response detection increased in parallel with amplitude reduction, as expected. The overall time required for the test was 15 minutes, including the time spent in volunteer preparation. The sensitivity was 97% for the three intensities, and the best specificity value was 100%, which was observed at 50 dB. DISCUSSION: The response analysis indicated that a screening protocol for school-aged children could include 1,000, 2,000, and 4,000 Hz and that the recording of ASSRs was highly sensitive to internal and external factors. Fifty dB SPL should be considered a cut-off criterion for screening purposes because this was the intensity level with a sensitivity of 97% and a specificity of 100%. CONCLUSION: The use of ASSRs might be particularly useful in school-aged children who have difficulty performing subjective hearing tests. The sensitivity and specificity data suggested that the use of ASSRs was feasible as an auditory screening tool. In order to determine a protocol for screening, future studies should include a larger sample and children with mild hearing loss.

OBJETIVO: relacionar as estratégias comunicativas adotadas na gestão de uma instituição de saúde com a percepção da comunicação pelos sujeitos participantes. MÉTODO: estudo descritivo-comparativo, com amostra por tipicidade, de recorte transversal. O estudo foi realizado em uma instituição de saúde do estado de Minas Gerais. Foram entrevistados 56 sujeitos de seis setores da instituição por meio de aplicação de questionário com 15 questões fechadas, que abordam desde a identificação do sujeito até as ações de planejamento, execução e avaliação da gestão e a percepção da comunicação e meios utilizados para se comunicar. Foi realizada análise descritiva e utilização do índice Kappa. RESULTADOS: os entrevistados, em sua maioria, relataram que as reuniões nas quais ocorre o planejamento não são exclusivas para tal atividade. Nelas sempre estão presentes as chefias diretas, ao contrário das indiretas. Quanto à execução das ações, observou-se que todos os membros da equipe se responsabilizam pelas atividades e compartilham informações durante o processo de trabalho. Foi relatado ainda que a avaliação ocorre de maneira assistemática e a presença das chefias direta e indireta é semelhante ao que ocorre na etapa de planejamento. Foi encontrado baixo grau de concordância entre as respostas. A percepção dos sujeitos sobre a comunicação foi considerada satisfatória, apontando que não é estabelecida relação direta entre a comunicação e o processo de trabalho. CONCLUSÃO: considera-se que os dados obtidos nesse estudo foram relevantes, de modo que permitiram discutir o papel da comunicação no sistema gestor pesquisado.
PURPOSE: to relate the communicative strategies adopted in the management of a health institution with the communication perception of the participants. METHOD: descriptive-comparative and cross-sectional study with a sample defined by type. 56 subjects from six sectors of the institution were interviewed with a closed questions questionnaire. For this study, we analyzed the questions related to stages of management and perception of communication at work. RESULTS: most of the respondents reported that the meetings in which planning occurs are not exclusive to this activity. The direct supervisors are always present, as opposed to the indirect ones. Regarding the implementation of actions, it was observed that all members of the sector take responsibility for the activities and share information during the process. It was reported that the evaluation occurs in an unsystematic way and the presence of direct and indirect leadership is similar to what occurs in the planning stage. It was found a low degree of correlation between the answers. The perception of the subjects about the communication was adequate, noting that no direct relationship is established between the communication and work process. CONCLUSION: it is considered that the data obtained in this study were relevant, so that led to discuss the role of communication in the system manager searched.
ABSTRACT
Este estudo tem como tema a análise do estado da arte sobre saúde auditiva no Brasil e a investigação da construção da produção científica nesta área. O objetivo é descrever, analisar e construir a linha histórica da produção científica em saúde auditiva no Brasil, no período de 2000 a 2010, tendo como referência a implantação, desenvolvimento e avaliação da política de Saúde Auditiva no contexto do Sistema Único de Saúde (SUS). As primeiras publicações encontradas são do ano de 2005. Com o passar dos anos, principalmente nos dois últimos, o número de publicações cresceu gradativamente. O eixo temático com maior número de artigos relacionados foi Usuários. O tema avaliação, com enfoque na satisfação do usuário, foi o mais abordado. Os temas gestão e capacitação de profissionais também foram recorrentes.
The theme of this study is the analysis of the state of art in hearing health in Brazil and the investigation of scientific production in this area. The aim is to describe, to analyze and to build the story line of scientific hearing health in Brazil during the period between 2000 and 2010; the reference were the deployment, development and evaluation of hearing health policy of the Sistema Único de Saúde (SUS). The first studies are from 2005. Since then, especially in the two last years, the number of studies grew gradually. The category Users was the one with more articles included. The theme evaluation, focusing on users' satisfaction, was the most explored, followed by management and enablement of health professionals.
