Resumo
Objetivo: Avaliar o desempenho do aplicativo PETIT (triagem automatizada em tablet), em comparação com a varredura audiométrica, na identificação de risco para alterações auditivas em escolares, utilizando fones de ouvido com cancelamento de ruído passivo. Método: Estudo observacional transversal com 122 crianças (05 a 08 anos) da rede pública municipal de Santana de Parnaíba. Foram realizados meatoscopia; triagem automatizada via tablet (com fones Sennheiser HD-280); triagem por varredura audiométrica. Parte da amostra realizou também audiometria convencional (padrão-ouro). Para análise, foram utilizados: testes binomial e de regressão logística binária, assim como cálculo de sensibilidade, especificidade e acurácia. Resultados: Houve associação significativa entre os resultados da triagem por varredura e do PETIT, assim como o coeficiente da variável preditora (audiometria convencional) foi estatisticamente significativo ao desempenho na triagem por varredura. Para o PETIT, verificou-se sensibilidade de 85,7%, especificidade de 100% e 99,18% de acurácia. Conclusão: Os resultados sugerem que esta ferramenta tem aplicabilidade promissora em ambiente escolar, podendo facilitar a identificação de crianças de risco para alterações auditivas.

Abstract
Purpose: To evaluate the performance of the PETIT application (automated tablet-based screening) compared with conventional sweep screening in identifying the risk of hearing impairment in school-aged children, using headphones with passive noise cancellation. Methods: Cross-sectional observational study including 122 children (aged 5 to 8 years) from the public school of Santana de Parnaíba. The following procedures were performed: otoscopy; automated hearing screening via tablet (with Sennheiser HD-280 headphones); and conventional sweep screening. Part of the sample also underwent pure-tone audiometry. Statistical analysis used binomial and binary logistic regression tests, along with the calculation of sensitivity, specificity, and accuracy. Results: There was significant association between the results of the sweep screening and PETIT, as well as the coefficient of the predictor variable (conventional audiometry) was significant to the performance in the sweep screening. For PETIT, a sensitivity of 85.7%, specificity of 100%, and accuracy of 99.18% were observed. Conclusion: The results suggest that this tool has promising applicability in schools for identifying children at risk of hearing impairments.
