Overview of newborn hearing screening activities in Latin America.

OBJECTIVE: Ascertain the status of early hearing detection and intervention services in Latin America. METHODS: Between June and November 2007, Gallaudet University, in collaboration with the U.S. Centers for Disease Control and Prevention Early Hearing Detection and Intervention Diversity Committee, disseminated a survey to 11 Latin American countries. It included questions about newborn hearing screening (NHS) procedures, the availability of intervention services for infants with hearing loss, and challenges in identifying infants with hearing loss. In addition, a literature review was conducted to help identify the status of NHS efforts in Latin America. RESULTS: Six countries (Chile, Costa Rica, Guatemala, Mexico, Panama, and Uruguay) and one U.S. territory (Puerto Rico) responded to the survey. Responses indicated that efforts to identify infants with hearing loss vary within and across countries in Latin America. In some countries, activities have been implemented at a national level; in others, activities have been implemented at a single hospital or region within a country. Common barriers to implementation of NHS programs include a lack of funding, screening and diagnostic equipment, public awareness, and personnel qualified to work with infants and young children. CONCLUSIONS: In spite of several barriers, NHS programs have been implemented in at least some facilities and regions in Latin America. Additional efforts are needed to expand NHS activities in Latin America.

OBJETIVO: Evaluar la situación de los servicios de detección e intervención tempranas de problemas auditivos en América Latina. MÉTODOS: Entre junio y noviembre del 2007, la universidad Gallaudet, en colaboración con el Comité de Diversidad del Programa de Detección Auditiva e Intervención Tempranas de los Centros para el Control y la Prevención de Enfermedades de los Estados Unidos, distribuyó un cuestionario en 11 países latinoamericanos. El cuestionario incluía preguntas acerca de los procedimientos de examen sistemático de la capacidad auditiva en recién nacidos, la disponibilidad de servicios de intervención para menores de un año hipoacúsicos y los retos para detectarlos. Además, se efectuó una revisión bibliográfica para ayudar a determinar el estado de las iniciativas de examen sistemático de la audición en recién nacidos en América Latina. RESULTADOS: Respondieron a la encuesta seis países (Chile, Costa Rica, Guatemala, México, Panamá y Uruguay) y un territorio de los Estados Unidos (Puerto Rico). Las respuestas indicaron que los esfuerzos para detectar a los menores de un año hipoacúsicos varían dentro de cada país y de un país a otro en América Latina. En algunos países se han realizado actividades a nivel nacional; en otros, en un único hospital o zona del país. Los factores que con frecuencia obstaculizan la puesta en práctica de los programas de examen sistemático de la audición en recién nacidos incluyen la falta de financiamiento, de equipos de tamizaje y diagnóstico, de concientización del público y de personal capacitado para atender a menores de un año y niños pequeños. CONCLUSIONES: A pesar de que existen varios obstáculos, se han ejecutado programas de examen sistemático de la audición en recién nacidos en al menos algunos establecimientos de salud y zonas de América Latina. Se necesitan esfuerzos mayores para ampliar estas actividades en América Latina.

Newborn hearing screening and follow-up: are children receiving recommended services?

OBJECTIVES: Newborn hearing screening programs have been implemented by all 50 states and most U.S. territories to detect hearing loss in infants and prevent delays in speech, language, and social and emotional development. To monitor progress toward national goals, the Centers for Disease Control and Prevention (CDC) collects data from state and territorial programs. This article summarizes findings from the CDC Early Hearing Detection and Intervention (EHDI) Hearing Screening and Follow-up Survey (HSFS) and provides a summary of recent efforts to identify infants with hearing loss in the U.S. METHODS: The HSFS was sent to representatives of U.S. EHDI programs to gather aggregate screening, diagnostic, intervention, and demographic data for 2005 and 2006. We analyzed these data to evaluate progress toward national goals. RESULTS: In 2005 and 2006, more than 90% of infants were screened for hearing loss. Of these infants, 2% in both years did not pass their final screening. Out of those not passing the final screening, approximately two-thirds were not documented as having a diagnostic finding. In both years, the reason reported for the majority of infants was loss to follow-up/loss to documentation (LFU/LTD). Although the majority of infants with permanent hearing loss were receiving intervention, more than 30% were classified as LFU/LTD and could not be documented as receiving intervention services. CONCLUSIONS: The HSFS enables the collection of more complete data that highlight the progress in screening infants for hearing loss. However, data indicate improvements are needed to reduce LFU/LTD and meet the national benchmarks.
