“…The referral rate for NICU and MCU populations was 40.5% and 15.4%, respectively. 18 Here, the initial referral rate was quite high in comparison with findings demonstrated in some other studies where the month-wise referral rate in a year ranged from 5.1% to 14.4%. 19 Mean averages of referral rates for the MCU and NICU newborns in that study were 11.98 and 11.75%, respectively.…”

Introduction: One to three per 1,000 live births suffers from significant hearing impairment. However, 2 to 4 per 100 infants who survived neonatal intensive care have some degree of sensorineural hearing loss. If hearing impairment in newborns is detected earlier, early management can prevent undesirable and often irreversible damage due to late detection. Early detection and the treatment of hearing impairment in children are essential for the development of communication skills, social skills, emotional well-being, and positive self-esteem. Unfortunately, this disability remains undetected for many newborns until it is too late to prevent undesirable and often irreversible damage. Unfortunately, not many studies were done on this topic in Bangladesh. The magnitude of the burden of hearing impairment in the study place might be identified by this study. The objective of the study: Hearing screening was done to see the status of hearing impairment in newborns admitted to NICU. Methodology: A prospective observational study was conducted in the department of neonatology, BSMMU. Newborn admitted to the NICU during the study period was the study population. The newborn who met the inclusion criteria was screened with TEOAE close to discharge from the NICU or before one month of age. A second screen was done with TEOAE again after one month of 1st screen but prior to 3 months of postnatal age if referred in 1st screen. Diagnostic ABR was done prior to 3 months of the postnatal age if referred in both the 1st and 2nd screen. Results: 426 valid recordings from 493 newborns admitted to the NICU enrolled consecutively constitute the basis of this study. Fourteen newborns were found to have hearing impairment among 426 newborns (3.3%). 2 newborns had unilateral hearing loss, and their hearing losses were moderate in nature. The other 12 newborns in their 24 ears had different grades of hearing loss. It was mild hearing loss in 3 ears, moderate in 9 ears, severe in 8 ears, and profound in 4 ears. Conclusion: Hearing screening showed that 3.3% of newborns in the NICU have a hearing impairment. It is still an underestimation considering the number of newborns who were lost to follow-up.

“…Their diagnosis is usually based on a combination of symptoms, laboratory parameters and clinical evaluations. Studies that show a significant association between sepsis or meningitis and hearing loss do not state the exact definition of diagnosis or the treatment guidelines . Diagnostic criteria and treatment regimens for sepsis and meningitis also typically vary across hospitals and settings, reducing the generalisation of these results .…”

Aim: Hearing loss in infants is often diagnosed late, despite universal screening programmes. Risk factors of hearing impairment in high-risk neonates, identified from population-based studies, can inform policy around targeted screening. Our aim was to determine the prevalence and the risk factors of hearing loss in a high-risk neonatal population. Methods:This was a retrospective cohort study of neonates hospitalised at the University and were part of the newborn hearing screening programme. Multivariable regression analyses using the lasso approach was performed.Results: Data were available for 4512 (43% female) neonates with a mean gestational age at birth of 35.5 weeks. The prevalence of hearing loss was 1.6%, and 42 (0.9%) neonates had permanent hearing loss. Craniofacial anomalies, hyperbilirubinaemia requiring exchange transfusion, oxygen supplementation after 36 weeks of gestation and hydrops fetalis showed associations with permanent hearing loss.Conclusion: Our findings of risk factors for hearing loss were consistent with other studies.However, some commonly demonstrated risk factors such as perinatal infections, meningitis, sepsis and ototoxic drugs did not show significant associations in our cohort. Targeted screening based on risk factors may help early identification of hearing loss in neonates.

“…The term "permanent congenital and early-onset hearing loss", or simply "hearing loss", is used more broadly to capture all degrees of hearing loss based on hearing threshold in the better ear averaged over frequencies 0.5, 1, 2, and 4 kHz, classified as: mild (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34), moderate (35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49), moderately severe (50-64 dBHL), severe (65)(66)(67)(68)(69)(70)(71)(72)(73)(74)(75)(76)(77)(78)(79), and profound (80)(81)(82)(83)…”

Newborn or neonatal hearing screening (NHS) is offered routinely in high-income countries as an essential and mandatory intervention for the early detection of infants with permanent congenital or early-onset hearing loss. However, NHS is rarely offered presently in the vast majority of low-and middle-income countries, which account for over 80% of the incidence and burden of permanent congenital or early-onset hearing loss worldwide. This review provides an overview of the current status of NHS programs in the most developmentally disadvantaged low-and middle-income countries with a per capita income of approximately US$6,000 or less against the backdrop of relevant recommendations for effective NHS programs. It highlights the key obstacles to the delivery and uptake of NHS services based on a review of available literature from the eligible countries. It proposes strategies for addressing these challenges and examines the crucial role of pediatricians and primary care physicians in providing leadership for the requisite multidisciplinary efforts to develop and promote effective NHS services in low-and middle-income countries.
