Abstract:

Background: Hearing impairment is one of the most common abnormalities in new-borns. It is often detected late and associated with delayed language, learning, and speech development. New born hearing screening is essential to detect impairment early for improved outcome. Aim & Objective: The aim of the study is to compare the prevalence of hearing impairment in high risk new-born and normal new-born and to evaluation different risk factors for hearing impairment. Materials & Methods: A prospective longitudinal case control study was conducted at Medical College, Kolkata for a period of nine months. In which a total of 764 babies (545-normal new-born/219-high risk new-born) were screened. High risk group allocation was performed using the New-born Hearing Screening Programme (NHSP) Risk Factor Screening guidelines. 1st TEOAE was done on all the babies at the time of discharge. The result of the test was interpreted as �??Pass�?� or �??Refer.�?� Babies having �??Refer�?? response were sent for 2nd TEOAE screening 4 weeks later. Babies having a �??Refer�?? response in the second stage were sent for the third stage BERA screening immediately. Absence of wave V in BERA was taken as confirmation of hearing impairment. Results: Prevalence of hearing impairment in the normal new-born [0.56%] was significantly less than the high risk group [1.86%] with p value-0.049. Significant risk factors identified were - meningitis (p value 0.001), congenital infection (p value < 0.001), mechanical ventilation >5 days (p value < 0.001), serum bilirubin > 20 mg/dl (p value < 0.001). Conclusion: Hearing screening should be done in all new-born babies. UNHS (universal newborn hearing screening) protocol using OAE and BERA can be implemented in Indian setting.
