Prevalence of permanent neonatal hearing impairment: systematic review and Bayesian meta-analysis Andrea M. L. Bussé Hans L. J. Hoeve Kazem Nasserinejad Allison R. Mackey Huibert J. Simonsz André Goedegebure 10.6084/m9.figshare.11794170.v1 https://tandf.figshare.com/articles/dataset/Prevalence_of_permanent_neonatal_hearing_impairment_systematic_review_and_Bayesian_meta-analysis/11794170 <p><b>Objective:</b> To investigate the variance in reported prevalence rates of permanent neonatal hearing impairment (HI) worldwide.</p> <p><b>Design:</b> A systematic review and meta-analysis was performed on reported prevalence rates of sensorineural and permanent conductive or mixed HI worse than 40 dB in neonates, detected as a result of a screening programme or audiometric study.</p> <p><b>Study sample:</b> For meta-analysis, 35 articles were selected, 25 from high-income countries and 10 from middle-income countries according to the world bank classification system.</p> <p><b>Results:</b> The prevalence rate of permanent uni- and bilateral HI worse than 40 dB in neonates varied from 1 to 6 per 1000, the overall prevalence was 2.21 per 1000 [1.71, 2.8]. In NICU populations the prevalence rate was higher with a larger fraction of bilateral cases. Although not significant, prevalence rates were slightly higher in Asia compared to Europe and the number of infants lost to follow-up appeared higher in countries with lower gross national income.</p> <p><b>Conclusion:</b> Substantial variations exist in prevalence rates of neonatal permanent HI across countries and regions. There is a strong need for more data from low-income countries to identify demographic factors that account for this variability in reported prevalence rates. Reporting these data in a uniform way is advocated.</p> 2020-02-03 16:51:59 Prevalence neonatal hearing impairment neonatal hearing screening systematic review meta-analysis
