“…John et al had shown refer rate of initial test of 6.4 % was reduced to 1.6 % on subsequent tests [16]. In present study refer rate of initial study of 10 % was reduced to 1 % on subsequent follow up tests.…”

“…According to John et al, 2009, low birth weight was the most common risk factor in high risk babies, which accounts for 26 (56.52 %) out of 46 high risk babies [16]. Babies admitted to a neonatal intensive care unit for more than 48 h are 10.2 times more likely to have a permanent hearing loss than those who did not undergo Meningitis-most common cause of acquired hearing loss is childhood meningitis.…”

“…History of blood exchange due to Hyperbilirubinemia and positive family history were not significantly different between two groups. Our OAE refers rate in comparison to the study conducted in Thailand [exclude NICU admission] (6.1%) [6], India (6.4%) 7 and Spain (6.7%) 8 on one side and Brazil(25.3%) 9 , the U.S (2.3%) 10 and Babol,Iran (10.8% ) 21 on the other side; refer rate variation may be explained by the number of births per year in each center of the screening 10 and age in which the first OAE was carried out which may be affected by debris or buid in the external or middle ear in early infancy 7,11 . However, this rate should not exceed upper limit defined by JCIH who recommended that failures in the first stage screening should not surpass 10% 12 .…”

“…Although OAE screening is quicker, easier and more cost-effective to perform than the ABR, it may be affected by debris or ûuid in the external or middle ear resulting in referral rates of 5 to 20% when screening is performed between the ûrst 24 hours of life 7,11 ABR screening requires the infant to be in a quiet state, but it is not affected by middle or external ear debris. Referral rates lower than 4% may be achieved when OAE is combined with automated ABR in a two-step screening system 11 Since OAE is quick and cost effective compared to ABR, retesting with OAE makes the universal screening program more feasible especially when there are large numbers of newborns and low financial support, as in developing countries 7 . In the present study, the main risk factors for hearing loss were history of NICU admission, followed by low birth weight (Table 2).…”

Hearing loss compromises optimal development of language and communication unless effective intervention is started within the ûrst year of life. Despite the JCIH recommendation as universal screening of all infants for hearing loss within the first few months of life; only some countries were successful in executing it. This study was undertaken in order to determine the most important predictors of Otoacoustic emission (OAE) as initial hearing screening of infancy in south of Iran. This may help in targeted hearing screening in high risk infants. The present study is a prospective cohort study examining all newborns throughout 2013to2014 delivered in Emam Khomeini hospital, Ahvaz, Iran. The neonatal hearing screening was carried out by portable transient evoked automated otoacoustic emissions (OAE) before discharge from the hospital. The Association between probable predictors (birth weight, history of blood exchange due to Hyperbilirubinemia, family history of hearing loss and history of admission in neonatal intensive care unit (NICU) for more than 48 hours) and the rate of failure in the screening was then analysed. During the study, 1850 children were born in the maternity ward of this hospital. The frequency of hearing screening refers rate was obtained at 9.8%. history of NICU admission and Low birth weight (<1500 gr) were significantly associated with hearing impairment as measured by OAE (P<0.001for both of them). History of blood exchange due to Hyperbilirubinemia and positive family history were not significantly different between two groups. History of NICU admission and low birth weight are two significant predictors for OAE failure in south of Iran. So if universal newborn hearing screening is unavailable, targeted screening in high risk infants including those admitted to the NICU and newborns with low birth weight is highly recommended.

“…Our findings were similar to John et al (6.4%) and Gouri et al (5.30%). 15,16 But it contradicts Nagapoornima et al findings. 17 She did a similar study of screening for 279 high risk south Indian babies and reported a 1% prevalence rate of hearing impairment.…”

Background: Hearing loss in early life can have deleterious effects on child’s psychosocial, scholastic and social-emotional development. Early identification and timely intervention can provide the child with better speech and language development. This study has been done to estimate the prevalence of hearing impairment among high risk infants as per Joint Committee on Infant Hearing (JCIH) criteria and to study the risk factors associated with neonatal hearing impairment.Methods: This multicentric observational study was conducted among 613 high risk infants admitted and discharged from neonatal intensive care units (NICU) of Academy of Medical Sciences, Kannur, Kerala and Sri Siddhartha Medical College and Research Centre, Tumakuru, Karnataka, India (level III neonatology units with an NICU admissions of average around 1200 per year), during the period August 2015 - August 2016 (12 months). The babies were selected based on the JCIH 2007 criteria. All babies were subjected to behavioral audiometry (BA) and Oto Acoustic Emissions (OAE), preferably within 3 weeks. Those failing OAE were reevaluated at 6th week and with Auditory brain stem response (ABR) within 3 months time. Results: A total of 613 high risk babies were screened. 42 (6.76%) among them were having hearing impairment. The most common risk factors associated with hearing impairment was NICU stay for more than 24 hours, prematurity, low birth weight and meningitis/sepsis etc.Conclusions: Hearing impairment among high risk babies is not a rare condition. In our study, the prevalence was 6.76%. Low birth weight, admission to NICU for more than 24 hours, low APGAR, meningitis/sepsis, maternal and neonatal complications are significant risk factors for hearing impairment among neonates. This highlights the need for neonatal screening. Though we recommend a universal screening program, at least a targeted approach should be practiced in neonatal care. Those babies who are found to have hearing impairment should be closely followed up with early intervention and rehabilitation.
