Análise crítica de três protocolos de triagem auditiva neonatal

Abstract

Background: having knowledge about the validity of procedures for newborn hearing screening (NHS) is fundamental, once the purpose of these programs is to identify all newborns with hearing loss at an acceptable cost. Aim: to estimate the specificity and the false-positive rate of NHS protocols using transient evoked otoacoustic emissions (TEOAE) and automated auditory brainstem response (AABR). Method: participants were 200 newborns who were submitted to a hearing screening test between March and July 2006. Three protocols were analyzed: protocol 1, NHS was carried out in two steps using TEOAE; protocol 2, NHS was carried out in two steps using AABR; and protocol 3, NHS was carried out in one step, using the two procedures -testing with TEOAE followed by a retest with AABR for all the newborns who did not pass the TEOAE testing. Results: although there was no statistically significant difference when comparing the referral rates to audiological diagnosis obtained in protocols using TEOAE and AABR, the protocol using TEOAE referred four times more newborns. Protocol 3 presented the highest referral rate, with a statistically significant difference when compared to protocols 1 and 2. Conclusions: the false-positive rate and consequently specificity were better for the protocol using AABR, followed respectively by the protocol using TEOAE and using both TEOAE and AABR.

Triagem auditiva neonatal: caracterização da demanda/ território e exames auditivos

“…Amongst the most prevalent risk indicators present in the pass/fail groups, the following appeared in the greatest number: Family history and complications coming from the neonatal ICU. Other authors have also reached the same conclusion [15][16][17][18][19] . Another study also relates this indicator with a population of low risk NB 8 .…”

“…O objetivo do estudo proposto por Freitas et al (2009) foi estimar a especificidade e taxa de falsopositivo de protocolos de triagem auditiva neonatal UNESP Botucatu, I believe that in the next Congress Brazil will present pioneer data uniting speechlanguage and molecular data about stuttering.…”

“…The purpose of the study presented by Freitas et al (2009) was to estimate the specificity and the false-positive rate of newborn hearing screening (TAN), realizados com emissões otoacústicas evocadas transientes (EOET) e potenciais evocados auditivos de tronco encefálico automático (PEATEa) em 200 recém-nascidos. Após análise dos resultados, as autoras concluíram que a taxa de falsopositivo e conseqüentemente a especificidade foram melhores no protocolo com PEATEa, seguido dos protocolos com EOET e com EOET e PEATEa.…”
