“…Of the total 2534 neonates screened by the two stage DPOAE hearing screening protocol and final confirmatory test with BERA at the age of three months, we could detect a total of seven neonates (2 per 1000) with hearing impairment. This was in agreement with the other studies which respectively stated that the average incidence of hearing impairment in neonates was 1.8-4.00 per 1000 [9][10][11][12][13]. However, one study from Cochin shows hearing loss in 10.3 per 1000 in high risk category [14].…”

Deafness is the most common curable childhood handicap. It is a well recognised fact that unidentified hearing impairment can adversely affect optimal speech and language development and therefore academic, social and emotional development. Universal neonatal hearing screening programmes are implemented in many developed countries. However it is still in its early stage in India. The incidence of hearing impairment in India is 1-6 per thousand newborns screened (Paediatrics 19:155-165, 1998; Indian J Paediatr 74(6):545-549, 2007; Status of Disability in India, pp 172-185 2000). To determine the incidence of permanent hearing loss of moderate to evere variety in neonates taking care in a tertiary care rural based hospital in Gujarat. It was a non randomised observational study done for duration of 3 years. All neonates born in Shri Krishna Hospital underwent screening using two stage protocols with DPOAE test and final confirmation done with BERA. Total 2534 neonates were screened out of them 52 failed and 2482 (97.94 %) neonates passed in the 1st DPOAE test with 2.05 % refer rate. Total 7 (2 per 1000) neonates were detected with hearing impairment. 10 % neonates had one or other high risk factor. Out of high risk neonates, 1.8 % were diagnosed with hearing impairment in high risk group. Overall the follow-up rate was 72.7 %. Hospital based universal hearing screening of new born before discharge is feasible at a rural based tertiary care centre. Non specialist staff is invaluable in achieving a satisfactory referral rate with two stage hearing screening protocol. However, more efficacious tracking and follow up system is needed to improve the follow up rate for diagnosis.

“…Reported overall TEOAE referral rates for subjects from NHS programs in developing countries vary considerably from those for our study (37.9%) with referral rates of 33.2% reported for Nigeria, 30% in Brazil, and 10.5% in Turkey [7,19,37]. The overall AABR screen referral rate per subject in this study (16.7%) was 15 higher than AABR MB 11 screening programs reported from other countries such as India (9.1%), Germany (3.8%) and Turkey (2%) [35,37,43]. A number of factors contribute to the higher refer rate in our study apart from the fact that this study was not an evaluation of an existing NHS program.…”

“…Most importantly however the higher average refer rate for both TEOAE and AABR is largely due to the large number of ears screened within 24 hours post birth. Other studies typically screened primarily before hospital discharge but at least 48 hours post birth [7,35,37,43].…”

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

“…The possible effect this can have on underestimating hearing loss prevalence has been lamented in several reports. A single hospital study in India reported only 58 of 164 (35.4%) infants attended for confirmatory screening (Augustine et al, 2013). Similarly, in a targeted surveillance program in England, of 69,050 infants with risk factors who were eligible for follow-up screening, appointments were accepted for barely half (55.3%) of the qualifying infants (Wood, 2013).…”

Neonatal hearing screening — Experience from a tertiary care hospital in Southern India

Abstract: Neonatal hearing screening using BERAphone is a feasible service. The estimated prevalence of confirmed hearing loss was comparable to that in literature. Overcoming the large numbers of loss to follow-up proves to be a challenge in the implementation of such a program.
