“…The prevalence of hearing impairment was lower than expected, so that the study was potentially underpowered. Using only OAE to screen children under age 4 may have led to incorrect classification of cases/non‐cases , although OAE accuracy measures for identifying hearing impairment have shown good performance, including low rates of false‐positive and false‐negative results . Despite the ENT nurses' training in diagnoses, these were made in the field with limited equipment available, which made it difficult to determine the causes reliably, and consequently, more than one‐third of cases were of unknown aetiology.…”

Abstractobjective To estimate the prevalence and causes of hearing impairment in Fundong Health District, North-West Cameroon.methods We selected 51 clusters of 80 people (all ages) through probability proportionate to size sampling. Initial hearing screening was undertaken through an otoacoustic emission (OAE) test. Participants aged 4+ years who failed this test in both ears or for whom an OAE reading could not be taken underwent a manual pure-tone audiometry (PTA) screening. Cases of hearing impairment were defined as those with pure-tone average ≥41 dBHL in adults and ≥35 dBHL in children in the better ear, or children under age 4 who failed the OAE test in both ears. Each case with hearing loss was examined by an ear, nose and throat nurse who indicated the main likely cause.results We examined 3567 (86.9%) of 4104 eligible people. The overall prevalence of hearing impairment was 3.6% (95% confidence interval [CI]: 2.8-4.6). The prevalence was low in people aged 0-17 (1.1%, 0.7-1.8%) and 18-49 (1.1%, 0.5-2.6%) and then rose sharply in people aged 50+ (14.8%, 11.7-19.1%). Among cases, the majority were classified as moderate (76%), followed by severe (15%) and profound (9%). More than one-third of cases of hearing impairment were classified as unknown (37%) or conductive (37%) causes, while sensorineural causes were less common (26%).

“…We have performed DPOAE test as compared to most of the studies in the literature where they have used TEOAE because even though TEOAE is simpler and quicker to perform, DPOAE is frequency specific and also can evaluate higher frequencies 16 and it has higher sensitivity of around 97.57% and specificity of 95.39% with comparatively less false positive rate while TEOAE has sensitivity of 96.49% and specificity of 90.60%. 17…”

Purpose: To determine whether preeclampsia and gestational diabetes mellitus is a risk factor for cochlear damage and sensorineural hearing impairment in infants. Materials and Methods: Longitudinal study was conducted in 2 tertiary referral centers. 1068 neonates were included, who were born to preeclampsia, gestational diabetes mellitus, and healthy mothers. The hearing evaluation was done using DPOAE on day 2 and for those who failed the initial DPOAE on day 2, underwent repeat DPOAE on day 15, ABR was done on day 30 if repeat DPOAE was Refer. The results were compared between the groups and analyzed. Results: On initial DPOAE, bilateral ear absent DPOAE rates were 19.5%, 15.8%, and 3.5% among preeclampsia, Gestational Diabetes Mellitus (GDM), control groups respectively. The difference was statistically significant ( P < .001). Also it was noted that absent DPOAE was significantly high at low and mid frequencies (1000, 2000, 3000, and 4000 Hz) in bilateral ear. However the difference in repeat DPOAE among the groups were not significant (Right ear P = .17, Left ear P = .31). Infants who failed repeat DPOAE test underwent ABR test in which 3 of GDM group, 2 infants of preeclampsia group and 1 infant of control group had absent ABR test. Conclusion: This study reveals that GDM and preeclampsia showed remarkable association of hearing loss at lower and mid frequencies which was transient. The prevalence of absent DPOAE was corresponding to the severity of the maternal conditions under the study.

“…A high correlation between positive screening and negative rescreening (r = 0.977, p < 0.001) shows the importance of organizing a screening system at three levels. It is clear that a large proportion of children that have a TEOAE refer at the first examination, which may be due to fluid in the ear canal or middle ear, anxiety, restlessness of the child during the examination, or impaired acoustic conditions during the examination (Maung et al, 2016). At the second examination, these children often already receive a TEOAE pass.…”

The study aims to evaluate the number of examined newborns and the results of screening for twelve years (2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019) and to assess the effectiveness of the established system of neonatal hearing screening. Design and methods: The study was designed as a retrospective longitudinal data analysis. The data included all the children (19,043) born in the hospital and also children (74) transferred from other healthcare facilities. A total of 19,117 children were included in the research group. Results: In the first three years, a higher number of children did not pass the hearing screening, which was followed by a declining trend in the following years. After the first year of screening ( 2008), there was an improvement in diagnosis linked with a decrease in false-positive screening results (from 9.4% to 6.4%; p = 0.002). From 2008 to 2015, the ratio of children with positive screening to those with negative screening had a steady or declining trend. Conclusions: The results showed a reduction in false-positive results after the first year of the screening program, probably due to improved care management and a gradual increase in the skills of the nurses performing the screening. Practice implications: The cornerstones of neonatal hearing screening are a sufficient number of trained neonatology nurses, their mutual substitutability and the availability of a hearing screening device in the newborn ward every day. The results imply the importance of periodic evaluation of the obtained data, enabling early detection of possible deficiencies in the hearing screening system.
