ABSTRACT
Introducción: La detección precoz de hipoacusia permanente en lactantes beneficia el desarrollo integral del paciente. Los programas cuyo objetivo es la identificación universal de hipoacusia debieran tener como meta determinados criterios de calidad en su ejecución. Objetivo: El objetivo del presente trabajo es comunicar los resultados del Programa de Detección Precoz de Hipoacusia en el Hospital Padre Hurtado. Material y método: Se incluyen los recién nacidos entre el 1 de enero de 2014 y el 31 de agosto de 2016. Los pacientes sin factores de riesgo para hipoacusia congénita se evalúan con examen de emisiones otoacústicas, y los pacientes con factores de riesgo con potenciales auditivos automatizados de tronco encefálico. Refieren aquellos pacientes con exámenes alterados en forma uní o bilateral. La etapa diagnóstica incluye potenciales auditivos evocados con tono, impedanciometría de alta frecuencia y audiometría de refuerzo visual. Los pacientes con diagnóstico de hipoacusia permanente son amplificados e inician proceso de habilitación. Resultados: En el período de estudio el universo a evaluar fue de 12.313 recién nacidos. Se completó la etapa de pesquisa en 98.4% con una tasa de referencia de 0.6%. 79 pacientes pasaron a etapa diagnóstica, completaron su evaluación antes de 3 meses en 95% de los casos. Se confirmó hipoacusia sensorioneural en 7 casos, con una tasa de 0.56 por 1.000 recién nacidos vivos. En 57% de los pacientes se amplificaron antes de los seis meses de vida. Conclusiones: El Programa de Hipoacusia Congénita del Hospital Padre Hurtado cumple con los indicadores de calidad recomendados en los ítemes de pesquisa y diagnóstico. En la etapa de habilitación con audffonos esto se realiza antes de los seis meses de vida sólo en 57% de los casos.
Introduction: Quality indicators of the newborn hearing screening program in Hospital Padre Hurtado. Aim: Asses the accomplishment of quality indicators of the newborn hearing screening program in Hospital Padre Hurtado, Chile, as proposed by the Joint Committee on Infant Hearing Loss (JCIH). Material and method: Two stage screening protocol: otoacoustic emissions for babies in the well-infant nursery and automated auditory brainstem responses for those in the intensive care unit orwith risk factors. If they fail one or both ears they proceed to a comprehensive audiological assessment. Results: 12.313 live births between 01/01/2014 and 108/31/16, 12.103 were screened before discharge (98.4%). 79 cases proceeded to diagnostic assessment, referral rate 0.6%. 95% infants completed audiological evaluation before three months, seven cases were diagnose with permanent sensorineural hearing loss for a prevalence of 0.56 per 1000 live births. Amplification was provided before 6 months of age in 57% of deaf children. Conclusions: Quality indicators of the JCIH are met by our newborn hearing screening program with the exception of adequate timing for the provision of hearing aids: 57% before six months of age.

Background: Data is scarce in Colombia when dealing with the current circumstances of programs for detectinghearing loss in children younger than six months and, therefore, statistical data is limited on congenital or earlyacquireddeafness. Studies have been conducted in the country on detection and prevention of hearing problems inthe healthcare institutions in Antioquia, Quindío, Cauca, Valle, and Risaralda. All these studies were carried outbetween 1993 and 1995 and included children older than one year of age, which shows evidence of the lack ofknowledge about the importance of early detection in the hearing-communicative health of children.Objective: To identify the current procedures and protocols to detect hearing loss in children younger than sixmonths in Cali through a descriptive research in different healthcare institutions of the city. Methods: A descriptive study was carried out with a population of 722 private, public and/or mixed Health Service Providing Institutions from the city of Cali, registered in the database of the Department of Health of Valle del Cauca,Colombia in February 2007. A list was filled out to determine which of these institutions had services like delivery room and/or growth-development programs and/or audiology services and it was found that these aspects were met in 151 institutions that constituted the research sample. Thereafter, a survey was applied in these institutions to identify theprocedures utilized for hearing loss detection, the health professionals that carry this out, and the follow up and thespeech-language treatment performed to the children detected. Results: 95% of the healthcare institutions surveyed (144 institutions) do not perform procedures to detect hearing loss in children younger than six months. Only six of the private-sector institutions in Cali performed such procedures. The procedures used by these six institutions are all performed with equipment and protocols forobjective tests.

PURPOSE: Hearing loss is one of the most common major abnormalities present at birth, which has an incidence of 1 to 3 per 1,000 newborn infants in the well-baby nursery population, and 2 to 4 per 1,000 infants in the intensive care unit population each year. If early undetected, will impede speech and language. The purpose of this study was to confirm in prevalence of neonatal hearing loss and to establish a common screening method adjusted to our country and to emphasize the importance of early detection. MATERIALS AND METHODS: TEOAE (transient evoked otoacoustic emission) were performed in 5,512 newborn infants in the well-baby nursery. The tests were performed daily until the infant had passed. Failed infants were followed at the outpatient clinic for re-tests. ABRs were performed for the confirmation of hearing loss those who had failed 3 TEOAE tests. RESULTS: The average test durations for right and left TEOAE were 67+/-50 sec and 72+/-56 sec respectively. There was no difference in test durations of the first TEOAE between before 24 hours and after 24 hours of life. 89% of tested infants passed during admission and the rest were followed at the outpatient clinic for the further studies. Eight infants were diagnosed with hearing loss on ABR. Overall time spent for the diagnosis of hearing loss was less than 3 months. CONCLUSION: TEOAE is a simple and useful screening method for the identification of hearing loss in infants. TEOAE must be necessary to universal screening of all infants.

BACKGROUND AND OBJECTIVES: Hearing impairment is a common congenital disability of the newborn, which has an incidence of 1.5 to 3 per 1,000 infants each year. The identification of this problem is difficult and many of these children are not identified until 2-3 years of age if not screened at birth. The purpose of this study is to establish a common screening method adjusted to our country and to emphasize the importance of early diagnosis of neonatal hearing loss. MATERIALS AND METHODS: TEOAE were performed in 1,459 infants from March to December, 1998 at Ajou university hospital. The tests were performed daily until discharge if the infant had failed the first test, and were followed at the outpatient clinic. Hearing loss was confirmed by ABR. RESULTS: The average test time of TEOAE was 102.6 seconds. Test time after 24 hours of birth was shorter than before 24 hours, and was shorter in female compared to male infants. Pass rate after 24 hours was higher than before 24 hours and 86% of tested infants passed during admission. Thirty-one out of 213 infants failed to follow-up at the outpatient clinic. Two were diagnosed with unilateral hearing loss on ABR. CONCLUSION: TEOAE is a simple and useful screening method for the identification of hearing loss in infants.
