“…The correlation coefficient was found with a value of r = 0.23, which suggested that the two data-sets are not well related. In a previous study by Holtby et al on hearing screening [17], the tympanometric data from 610 English school children showed a sensitivity of 74.4%, but a PPV of 37.6%. The discrepancy between the data from the present and the Holtby study is probably procedural, since in the latter the tympanometric measurements were taken twice, following the typical 3-stage neonatal screening paradigm [1].…”

“…Each procedure was compared to an in situ conventional pure-tone audiometry. While screening procedures based on tympanometry and otoacoustic emissions have been previously field-tested in various school environments [6,7,[16][17][18], the automated screening audiometry is relatively new. Positive feedback on the use of automated audiometry in screening has been recently reported by McPherson et al [19], in a study on 80 school children tested with automated and conventional audiometry.…”

“…Five evaluations reported in four studies [36][37][38][39] included in the original 2007 HTA report and three 17,27,30 in the current update evaluated the accuracy of audiometry-based tests. The original five studies, all assessing pure-tone sweep devices, reported sensitivities ranging from 86% to 100% and specificities from 65% to 99%.…”

BackgroundIdentification of permanent hearing impairment at the earliest possible age is crucial to maximise the development of speech and language. Universal newborn hearing screening identifies the majority of the 1 in 1000 children born with a hearing impairment, but later onset can occur at any time and there is no optimum time for further screening. A universal but non-standardised school entry screening (SES) programme is in place in many parts of the UK but its value is questioned.ObjectivesTo evaluate the diagnostic accuracy of hearing screening tests and the cost-effectiveness of the SES programme in the UK.DesignSystematic review, case–control diagnostic accuracy study, comparison of routinely collected data for services with and without a SES programme, parental questionnaires, observation of practical implementation and cost-effectiveness modelling.SettingSecond- and third-tier audiology services; community.ParticipantsChildren aged 4–6 years and their parents.Main outcome measuresDiagnostic accuracy of two hearing screening devices, referral rate and source, yield, age at referral and cost per quality-adjusted life-year.ResultsThe review of diagnostic accuracy studies concluded that research to date demonstrates marked variability in the design, methodological quality and results. The pure-tone screen (PTS) (Amplivox, Eynsham, UK) and HearCheck (HC) screener (Siemens, Frimley, UK) devices had high sensitivity (PTS ≥ 89%, HC ≥ 83%) and specificity (PTS ≥ 78%, HC ≥ 83%) for identifying hearing impairment. The rate of referral for hearing problems was 36% lower with SES (Nottingham) relative to no SES (Cambridge) [rate ratio 0.64, 95% confidence interval (CI) 0.59 to 0.69;p < 0.001]. The yield of confirmed cases did not differ between areas with and without SES (rate ratio 0.82, 95% CI 0.63 to 1.06;p = 0.12). The mean age of referral did not differ between areas with and without SES for all referrals but children with confirmed hearing impairment were older at referral in the site with SES (mean age difference 0.47 years, 95% CI 0.24 to 0.70 years;p < 0.001). Parental responses revealed that the consequences to the family of the referral process are minor. A SES programme is unlikely to be cost-effective and, using base-case assumptions, is dominated by a no screening strategy. A SES programme could be cost-effective if there are fewer referrals associated with SES programmes or if referrals occur more quickly with SES programmes.ConclusionsA SES programme using the PTS or HC screener is unlikely to be effective in increasing the identified number of cases with hearing impairment and lowering the average age at identification and is therefore unlikely to represent good value for money. This finding is, however, critically dependent on the results of the observational study comparing Nottingham and Cambridge, which has limitations. The following are suggested: systematic reviews of the accuracy of devices used to measure hearing at school entry; characterisation and measurement of the cost-effectiveness of different approaches to the ad-hoc referral system; examination of programme specificity as opposed to test specificity; further observational comparative studies of different programmes; and opportunistic trials of withdrawal of SES programmes.Trial registrationCurrent Controlled Trials ISRCTN61668996.FundingThis project was funded by the NIHR Health Technology Assessment programme and will be published in full inHealth Technology Assessment; Vol. 20, No. 36.

ResumoObjetivo: realizar a avaliação da audição e o levantamento da prevalência de deficiência auditiva em amostra de crianças, na faixa etária de 3 a 6 anos, em creches e pré-escolas municipais de São José do Rio Preto, SP.Métodos: foram realizadas audiometrias em campo livre para triagem, como primeira etapa, em 103 crianças de ambos os sexos, na referida faixa etária, em 8 creches e 8 pré-escolas previamente selecionadas. As crianças que apresentaram alterações audiométri-cas na triagem foram encaminhadas ao ambulatório de fonoaudiologia da instituição para realização de audiometria tonal convencional, em uma segunda etapa. A classificação da deficiência auditiva, em relação ao grau, foi feita segundo os critérios da OMS.Resultados: foram encontradas alterações na função auditiva em dez crianças (9,70%, DP % =0,96) da população do estudo. Destas, uma criança (0,97%, DP % =0,96) do sexo masculino apresentou deficiência auditiva condutiva de grau leve na orelha esquerda (média OE=35 dB) e 9 crianças (8,73%, DP % =2,78) apresentaram alterações nos limiares auditivos, por via aérea, nas freqüências agudas de 4.000, 6.000 e/ou 8.000Hz. Cento e duas crianças (99,03%, DP % =0,96%), sendo 55 do sexo masculino (53,39%, DP % =4,90%) e 47 do sexo feminino (45,64%, DP % =4,90%), não apresentaram deficiência auditiva, pelos critérios da OMS.Conclusões: a prevalência de 9,7% de alterações na função auditiva encontrada na população do estudo vem a comprovar a necessidade da implantação de programas de prevenção e diagnósti-co precoce da deficiência auditiva. AbstractObjective: to estimate the prevalence of deafness in children 3-6 years old in day-care centers of São José do Rio Preto, SP, Brazil.Methods: we used free-field audiometry to screen 103 children from 8-selected day-care centers. Children with abnormal examination results were referred to the speech therapy outpatient service to undergo pure-tone conventional audiometry. We adopted the WHO classification for degree of deafness.Results: audiometric dysfunctions were present in 10 children (9.70%; SD=0.96) with one boy showing left ear mild conductive hearing loss (mean LE=35 dB), while 9 children (8.73%; SD=2.78) showed alterations in air-conduction threshold in 4000, 6000 or 8000 sharp frequencies. Out of 102 children (99.03%; SD=0.96), 55 boys (53.39%; SD=4.9) and 47 girls (45.64%; SD=4.9) presented no hearing loss according to the WHO criteria.Conclusions: the prevalence of 9.7% audiometric dysfunctions found in this study indicates that deafness prevention programs should be organized.J Pediatr (Rio J) 2001; 77 (2): 124-30: deafness, audiometry, child day-care centers.Avaliação da audição em crianças de 3 a 6 anos em creches e pré-escolas municipaisHearing evaluation in children aged 3-6 years in day-care centers
