“…The risk of high TEOAE referral rates before 48 hours post birth, as demonstrated in this study, make it difficult to overlook initial AABR screening even in a resourceconstrained environment like South Africa [15]. However, OAE screening techniques are typically the most widely used for initial or two-stage NHS programs worldwide, including in South Africa.…”

“…In public hospitals in South Africa infants may be discharged within 24 hours post birth when TEOAE refer rate is highest [36,39]. The constraint of birthing facility discharge typically from 6 hours after birth for healthy babies and their mothers may necessitate the introduction of an initial or second-stage screening with AABR to minimize the referral rates prior to diagnostic evaluation [15,38]. In this study newborns initially screened with AABR at 48 hours or later had the optimal subject refer rate of 5.6% when compared to the recommended benchmark of less than 4% [11].…”

“…presence of amniotic fluid and mesenchyme), making it more likely that newborns will refer with OAE screening than AABR screening [13,14]. Environmental factors such as excessive ambient noise in the test environment or test skills and experience of the screening staff may also negatively affect screening outcomes for both OAE and AABR [15]. Falsepositive results may lead to parental anxiety and worry as well as monetary costs resulting from parents' lost time from work, transportation to health care facilitates, 3 unnecessary tests, and probably more consequential costs and follow-up defaults which is a matter of special concern in developing countries like South Africa [16,17].…”

“…The recommended time for NHS screening after birth is later than 24 hours to avoid the increased incidence of transient outer and middle-ear conditions affecting screening outcomes in the first hours post birth [9,15]. Screening with an OAE technique within the first 24 hours post birth reportedly results in referral rates as high as 20% [9,18,19].…”

Objective: Early discharge of newborns (<24 hours after birth) from birthing centres is an important barrier to successful newborn hearing screening (NHS) in developing countries. This study evaluated the outcome of NHS within the first 48 hours using an automated auditory brainstem response (AABR) device without the need for costly disposables typically required, and transient evoked otoacoustic emissions (TEOAE).Methods: NHS was performed on one hundred and fifty healthy newborns (300 ears) with TEOAE and AABR techniques before discharge at a hospital. A three-stage screening protocol was implemented consisting of an initial screen with TEOAE (GSI AUDIOscreener+) and AABR (Beraphone MB 11). Infants were screened at several time points as early as possible after birth. Infants were only re-screened if either screening technique (TEOAE or AABR) initially yielded a refer outcome. The same audiologist performed all TEOAE and AABR screenings. Results:Over the three-stage screen AABR had a significantly lower refer rate of 16.7% (24/144 subjects) compared to TEOAE (37.9%; 55/145 subjects). Screening refer rate showed a progressive decrease with increasing age. For both TEOAE and AABR, refer rate per ear screened 24 hours post birth was significantly lower than for those screened before 24 hours. For infants screened before 12 hours post birth, the AABR refer rate per ear (51.1%) was significantly lower than the TEOAE refer rate (68.9%). Overall AABR refer rate per ear was similar for infants screened between 24 to 36 hours (20.2%) and 36 to 48 hours (18.9%) but significantly lower than for TEOAE (40.7% and 41.9%, respectively). Lowest initial refer rates per ear (TEOAE 25.8%, AABR 3.2%) were obtained after 48 hours post birth. Conclusion:In light of the early post birth discharge typical in developing countries like South Africa, in-hospital screening with AABR technology is significantly more effective than TEOAEs. AABR screening with a device like the MB 11 is particularly appropriate because disposable costs are negligible.2

It is well known that false positive on newborn hearing screening increases cost and maternal anxiety and worry. We aimed to evaluate the influence of mode of delivery (cesarean, vaginal) and hospital type (private, public) on false positives first screening test based on screening age. Identification and control of these factors can reduce the rate of false positives. Overall, 2784 infants were evaluated by otoacoustic emissions test. Hearing screening test was performed before hospital discharge. Finally, rate of the false-positive between both delivery group and hospital types were compared on the basis of screening age. False-positive results are obtained when a condition is not present, but the test results indicate that it is present. False positive rate in the first screening test in vaginal delivery was significantly higher than cesarean delivery and rate of significantly decreased with screening age. This reduction was observed only in cesarean delivery. Also the rate of false positives in public hospital is 2.2 fold higher than private hospital ( = 0.000) and with increase in screening age, the rate of False positive is significantly reduced in private hospitals while this decrease is not observed in public hospital. Screening test be retarded as much as possible in cesarean group and private hospital and be conducted just prior to hospital discharge also in public hospital, screening test are done in a separate room. In this way, false positive can be reduced by about six times and the cost and concerns imposed by the rate of false positives minimized.

Introduction Congenital hearing impairment is one of the principal issues that make distress to families especially those with a family history of hearing problems. Early detection of hearing impairment can make a difference regarding cognitive, attention, learning, speech, and social and emotional development of babies. Otoacoustic test emission is a very common screening test that can be used to pick up early cases and relieve family stress. We tried to evaluate the factors that may disrupt our results regarding the OAE test. Methods A cross-sectional study included infants who were admitted to the nursery unit alone. Infants who were admitted to the NICU unit, infants with craniofacial anomalies, infants with vernix in the external auditory canal, and Infants with Stigmata associated with a syndrome known to include a sensorineural hearing loss were excluded from the study. Both transient evoked otoacoustic emissions (TEOAE) with distortion product otoacoustic emissions (DPOAE) Screening tests were performed by the same professional audiologist experienced in neonatal screening. Results A total of 1413 newborns (733 males and 680 females) were included in the study. Among them, 1368 babies (96.8%) passed the first OAE in both ears, while 45 babies (3.2%) didn't pass the first OAE in one or both ears.Significant correlations between the female gender and family history of congenital hearing loss with failure of the first OAE test results. Moreover, vaginal delivery (VD) infants had a 1.5-fold higher failure rates of first OAE test screening results in comparison to caesarian delivery (CD) infants. Conclusion Our study demonstrated higher failure rates of the first OAE in female infants, vaginal delivery infants, and infants with a family history of hearing impairment. It is recommended to postpone the first phase of hearing screening for those infants until the first scheduled vaccine appointment to achieve higher compliance attendance, and decrease family stress associated with false-negative results of the test.
