Objective - Early diagnosis and treatment of congenital and acquired hearing impairment in newborns is a key element for optimal speech development. The automated auditory brainstem response (AABR) method is considered to be superior to the otoacoustic emission (OAE) method, as it detects hearing deficit not only at the level of ear but also of neural origin. Recent recommendations suggest implementation of AABR to newborn hearing screening, to identify the group of newborns at higher risk of hearing impairment. Aim u2013 The aim of the study was to analyze the effectiveness of OAE and AABR used as screening tools for hearing impairment among infants. Material and methods u2013 The group of 350 infants (250 u2013 with risk factors of hearing deficit; 100 u2013 control group) was examined by means of both OAE and AABR before discharge from the hospital after birth. The risk factors of hearing deficit were recorded. Infants who failed the screening test and/or had risk factors were referred for further audiological evaluation.Results u2013 The results of OAE were positive in 4 newborns bilaterally and in 1 unilaterally. In 2 infants OAE was not performed due to anatomical defects or respiratory support. The results of AABR were positive in 7 newborns bilaterally and in 13 unilaterally. One newborn in whom both OAE and AABR were positive was finally diagnosed with bilateral sensorineural profound hearing deficit > 90 dB; the identified risk factor was congenital cytomegalovirus infection. Five newborns of the study group and one of the control group in whom OAE was negative and AABR was positive either unilaterally or bilaterally, finally have not been diagnosed with hearing deficit (false positive screening). Other infants in whom AABR was positive do not have the final diagnosis of hearing status yet. All newborns of the study group had at least one risk factor of hearing deficit u2013 the most frequent were treatment in the intensive care unit (90%), mechanical ventilation (83.3%), and ototoxic treatment (75.1%). One newborn with negative results of both OAE and AABR and with risk factors of hearing deficit (prematurity, very low birth weight, ototoxic treatment, treatment in NICU and mechanical ventilation) was diagnosed with moderate hearing deficit (30 dB and 50 dB) at the second level of screening program (false negative screening). AABR exam was assessed by the staff as more difficult and time consuming to perform (mean time of the exam 7.4 min; SD 7.19) when compared to OAE.Conclusions - The AABR method, recommended as gold standard for hearing screening in premature babies, is very useful in early diagnosis of hearing impairment. It allows for early identification of infants with hearing deficit as it examines the entire auditory pathway. However, it seems to be more difficult to perform when compared to OAE.

CONTEXT: Each year approximately 5000 infants are born in the United States with moderate to profound, bilateral sensorineural hearing loss (SNHL). Universal newborn hearing screening (UNHS) has been proposed as a means to speed diagnosis and treatment, and thereby improve language outcomes in these children. OBJECTIVE: To identify strengths, weaknesses, and gaps in the evidence supporting UNHS and to compare the additional benefits and harms of UNHS with those of selective screening of high-risk newborns. DATA SOURCES: A keyword search of MEDLINE, CINAHL, and PsycINFO databases for relevant papers published from 1994 to August 2001, using terms for hearing disorders, infant or newborn, screening, and relevant treatments. We contacted experts and reviewed reference lists to identify additional articles, including those published before 1994. STUDY SELECTION: We included controlled and observational studies of (1) the accuracy, yield, or harms of screening using otoacoustic emissions (OAEs), auditory brainstem response (ABR), or both in the general newborn population or (2) the effects of screening or of early identification and treatment on language outcomes. Nineteen articles, including 1 controlled trial, met these inclusion criteria. DATA EXTRACTION: Data on population, test performance, outcomes, and methodological quality were extracted using prespecified criteria developed by the US Preventive Services Task Force. We queried authors when information needed to assess study quality was missing. DATA SYNTHESIS: Good quality studies show from 2041 to 2794 low-risk, and 86 to 208 high-risk, newborns were screened to find 1 case of moderate to profound SNHL. The best estimate of positive predictive value is 6.7%. Six percent to 15% of infants who fail the screening tests are subsequently diagnosed with bilateral SNHL. In a trial of UNHS versus clinical screening at 8 months of age, UNHS increased the proportion of infants with moderate to severe hearing loss diagnosed by 10 months of age (57% vs 14%), but did not reduce the rate of diagnosis after 18 months of age. No good-quality controlled study has compared UNHS to selective screening of high-risk newborns. In fair- to poor-quality cohort studies, intervention before 6 months of age was associated with improved language and communication skills by 2 to 5 years of age. These studies had unclear criteria for selecting subjects, and none compared an inception cohort of low-risk newborns identified by screening to those identified in usual care, making it impossible to exclude selection bias as an explanation for the results. In a mathematical model based on the literature review, we estimated that extending screening to low-risk infants would detect 1 additional case before 10 months for every 1441 low-risk infants screened, and result in treatment before 10 months of 1 additional case for every 2401 low-risk infants screened. With UNHS, 254 newborns would be referred for audiological evaluation because of false-positive second-stage screening test results, versus 48 for selective screening. CONCLUSIONS: Modern screening tests for hearing impairment can improve identification of newborns with SNHL, but the efficacy of UNHS to improve long-term language outcomes remains uncertain.

We include information on the provisions of vaccines and their costs, on modes of delivery, and on the number of adverse events. [...] The incidence of these diseases will therefore reflect the efficacy of the vaccines and the degree of coverage that is achieved by the national immunization strategies. [...] The number of vaccines that are administered are based on the childhood immunization schedules, the degree of coverage in the childhood population, and the unit prices of the vaccines that are delivered. [...] Institute of Health Economics, Economics of Childhood Immunizations in Canada, May 2007 27 sEction thrEE pErformancE introduction In this section we address two issues - the cost-effectiveness of vaccies in preventing communicable diseases and the performance of the Canadian public health system in providing vaccine coverage for children. [...] The net benefits of the program depend on the total number of children vaccinated and the cost of the immunization program.

This systematic evidence review updates a prior review for the U.S. Preventive Services Task Force (USPSTF) on universal newborn hearing screening (UNHS) to detect moderate to severe permanent, bilateral congenital hearing loss (PCHL). In 2001, based on results of a prior systematic evidence review, the USPSTF concluded that the evidence was insufficient to recommend for or against routine screening of newborns for PCHL during the postpartum hospitalization (I Recommendation). The USPSTF provided additional specific conclusions about the evidence. They determined that methods of screening using otoacoustic emissions (OAEs) and auditory brainstem response (ABR) are highly accurate for identifying PCHL in newborns, and UNHS leads to earlier identification and treatment of infants with PCHL. They found that evidence was inconclusive regarding whether earlier treatment resulting from newborn screening leads to clinically important improvement in speech and language skills at age 3 years and beyond because existing studies had design limitations. The USPSTF considered that earlier identification and intervention may improve the quality of life during the first year of life, and prevent regret by the family over delayed diagnosis of PCHL, but limited data addressing these benefits existed. They were not able to determine whether potential benefits outweighed the potential harms of false-positive tests. This update focuses on critical evidence gaps that were unresolved at the time of the 2001 recommendation, and utilizes the format and methods of the prior systematic evidence review. The Joint Committee on Infant Hearing (JNIH), comprised of representatives from audiology, otolaryngology, pediatrics, education, and state speech and hearing programs, provides position statements and establishes practice standards for early identification, intervention, and follow-up care for infants and young children with hearing loss. According to the JCIH, hearing screening should identify infants at risk for specifically defined hearing loss that interferes with development. The targeted hearing loss for UNHS programs is permanent sensory or conductive hearing loss averaging 30 to 40 decibels (dB) or more in the frequency region important for speech recognition (approximately 500 through 4000 Hertz [Hz]). The focus of UNHS is on congenital as opposed to acquired or progressive hearing loss that may not be detected in the newborn period. The term “hearing impairment” is commonly used outside the U.S. instead of “hearing loss.” This systematic review updates the evidence from the prior 2001 USPSTF review for the following key questions: 1. Among infants identified by UNHS who would not be identified by targeted screening, does initiating treatment prior to age 6 months improve language and communication outcomes? 2. Compared with targeted screening, does UNHS increase the chance that treatment will be initiated by age 6 months for average risk infants? For high risk infants? 3. What are the adverse effects of UNHS and early treatment?

Infant hearing screening with the combination of otoacoustic emissions and automated auditory brainstem response test : Is it worth it?Introduction : The implementation of universal hearing screening could lead to the accurate and rapid diagnose of children with sensoneural hearing loss. The methods that are used most widely are otoacoustic emissions (OAEu2019s) and automated auditory brainstem response test (AABR) Methods and results : For a period of 1.5 year, 469 infants with or without risk factors had hearing screening with a protocol including medical history ,otoscopy ,tympanogram and both OAEs and AABR. According to our results the sensitivity of AABR was 97.54% and the specificity 87.5%. The OAEs had sensitivity 82.92% and specificity 100%.Conclusion : According to our results AABR are having higher sensitivity whereas OAEs have higher specificity .Consequently the combination of the two tests seem to be the most accurate for the earliest detection of sensoneural hearing loss.
