A 10-year retrospective analysis of newborn hearing screening in a tertiary hospital in Malaysia

Abstract

Background: Universal newborn hearing screening (UNHS) has been widely adopted worldwide as a standard of care because it enables the detection of congenital hearing loss early in life. Therefore, the concepts of regular measurement of performance using pre-determined quality measures are recommended for continuous improvement of the program. This study aimed to evaluate and update the performance of a UNHS program by measuring the recommended quality measures between 2010 and 2019. A retrospective study analyzing data of 50569 babies screened between January 2010 and December 2019 was performed. The pre-determined quality measures of coverage rate, initial referral rate, return to follow-up rate, diagnosis rate, and age at diagnosis were measured. Results: The average coverage rate was 95.5%, with all years achieving the recommended benchmark of ≥ 95% except 2014 (91.8%) and 2019 (89.5%). Generally, the initial referral rate (10%) exceeded the benchmark of ≤ 4%. The program only managed to reach the benchmark for initial referral rate in 2013, 2014, and 2015. Both quality indicators for return to follow-up and diagnosis rates also did not meet the ≥ 95% and ≥ 90% standards, respectively. The return to follow-up ranged from 62 to 72.7%, while the average diagnosis rate was 73.4% (60–100%). One hundred thirty-seven infants were diagnosed with hearing loss at a median age of 3.8 months (± 0.4 months), resulting in a prevalence of 0.27%. Conclusion: The findings demonstrated an excellent coverage rate but unsatisfactory performance for other quality indicators. Hence, the current program needs to be revisited to remain relevant and effective.
