“…Findings are consistent with results reported from a study on frequency of hearing impairment among full-term newborns in Yazd, Iran; where some newborns did not continue with the follow-up visits (19). They are also in agreement with findings from NHS programmes in maternity hospitals in Brazil (20), where loss to follow-up was lower for diagnostic assessment and ranged from 5% to 66% in public hospitals. One of the proposed reasons in this study was that diagnostic evaluations were conducted outside the maternity hospital (20), as in the current study where the protocol entailed diagnostic follow-up at the University clinic which is away from the hospitals where screening occurred.…”

Background: One of the most common problems noted in newborn hearing screening (NHS) programmes is the high rate of infants that are lost to follow-up at various stages of the programme. Objectives: The current study aimed to explore factors associated with follow-up return rate in a risk-based newborn hearing screening programme. Methods: A longitudinal, repeated measures research design was employed. Caregivers of participants who did not keep appointments while enrolled in a NHS programme were contacted to determine reasons for non-attendance. Results: Two hundred and sixteen of the 325 participants (66.5%) returned for the repeat screening. Follow-up return rate decreased significantly to below 50% for follow up diagnostic assessment. Reasons for non-attendance varied, with the most common reason being change of residential location. Results indicated a significant, but weak association between the hospital and whether or not infants returned for the repeat screening. The mean maternal age of mothers who returned with their newborns for diagnostic assessment was significantly higher than that of those who did not return. Conclusions: Reasons for follow-up default are influenced by contextual challenges, but may be improved by aligning appointments with other medical follow-up services. Follow-up return rate in the current study highlights the need to explore the need for risk-based surveillance programmes, as well as why follow-up return rates may differ between hospitals.

“…So, an unequal distribution, together with a reduced number of professionals working in public services, may contribute directly to the low NHS coverage in the northeastern region (8) . In the years of 2000, 2005 and 2010 there was an evolution in the speech-language and audiology area that can be observed when analyzing the procedures accomplished by the SLPA professionals.…”

“…Among the current challenges in newborn hearing screening (NHS) in the Brazilian scenario, there are the non-compliance to the program and the variability between protocols within different services. This last one makes the analysis and the comparison between programs difficult (8) . Spatial analysis can provide a visual evaluation of the distribution pattern of an event through maps.…”

Introduction: Universal Neonatal Hearing Screening (UNHS) is the recommended screening test for hearing loss diagnosis. Purpose: To perform a spatial analysis of the coverage of the Neonatal Hearing Screening (NHS) in the Northeastern of Brazil and to verify the possible association of the coverage with the number of Speech-Language Pathology and Audiology (SLPA) maternities and reference centers in hearing health. Methods: The reference population was of live newborns registered in the Live Birth Information System (Sistema de Informação sobre Nascidos Vivos -SINASC). For the data collection, electronic banks were set up in the Health Information Systems. Exploratory spatial analysis was performed using TabWin software; Descriptive statistical analysis: absolute and relative distribution and weighted mean calculation; Analytical, using Chi-square and Fisher's Exact tests, in which a significance level of 0.05 was adopted. Results: There was similarity throughout the Northeastern, regarding the low coverage of the NHS. The highest indices were concentrated in specific areas and there was a homogenous distribution among states. However, the states of Piauí and Paraíba stand out as to the frequency of coverage in municipalities with the NHS service. It was found an association between the coverage and the number of maternities, Speech-Language Pathology and Audiology and centers of reference in hearing health. Conclusion:The low coverage of the triage prevails throughout the Northeastern, and the best coverages are found in peculiar areas, where the large population centers are located. There was association with the lack of Speech-Language Pathology and Audiology enrolled in the Unified Health System, centers of reference in hearing health and the number of maternities.

Objective: The aim of the present study was to examine the relationship between the results of the transient otoacoustic emission (TEOAE) test used in neonatal hearing screening and the results of the umbilical cord blood (UCB) analysis in neonates.Methods: This retrospective study included 209 neonates born in the obstetric unit at the 37 th gestational week. Based on the results of the TEOAE test, the neonates included in the study were divided into two groups as the study group composed of those "REFER" (n=141) and the control group consisting those "PASS" (n=68) the test. The UCB sampling procedure was performed on all neonates. In the blood samples, the pH parameters were evaluated by using glass electrodes, and the pCO 2 and pO 2 parameters were evaluated directly by using sensitive electrodes.Results: When the additional maternal diseases were compared with the TEOAE results, the ratio of hypothyroidism was found to be statistically higher in the study group (p<0.05). In terms of the pO 2 , pCO 2 , HCO 3 , and pH values obtained as a result of analyzing the UCB samples, there was no statistically significant difference between the groups (p>0.05). Conclusion:The results of the present study showed that there was no statistically significant difference between the results of UCB analysis and the TEOAE test. However, we believe that conducting a larger study evaluating other parameters and employing UCB analysis would be useful, and UCB evaluation, which is an inexpensive, easy and effective method in determining hypoxia in neonates, might be a significant marker in cases at risk of hearing loss.
