Insights
Implementing universal newborn hearing screening using transiently evoked otoacoustic emissions (TEOAEs) reduced missed screenings and follow-ups. This program effectively identifies congenital hearing loss in newborns.
Area of Science:
- Audiology
- Neonatal care
- Public health
Background:
- Iaso maternity hospital implemented a universal newborn hearing screening program using transiently evoked otoacoustic emissions (TEOAEs).
- A pilot study preceded the program's establishment.
- The program aimed to improve outcomes by comparing successive newborn groups.
Purpose of the Study:
- To evaluate the effectiveness of a universal newborn hearing screening program.
- To compare outcome measures between two distinct screening periods.
- To identify improvements in screening and follow-up rates.
Main Methods:
- Data from two groups of full-term newborns were analyzed.
- The first group (3 years) and second group (2 years) were screened using TEOAEs.
- Newborns failing initial tests received repeat TEOAEs; those with absent emissions were referred for follow-up.
Main Results:
- The first group included 22,195 newborns; the second included 25,032.
- Refer rates decreased from 3.1% to 2.1%.
- The 'missed to follow-up' rate significantly reduced from 72.2% to 58.2%.
Conclusions:
- Modifications to the screening protocol reduced the rates of missed screenings and follow-ups.
- Universal newborn hearing screening is a feasible method for identifying congenital hearing loss.
- The program demonstrates cost-effectiveness in early detection of hearing impairment.
Objective:
Following a long period of pilot study, Iaso maternity hospital established a universal newborn hearing screening program based on transiently evoked otoacoustic emissions (TEOAEs). The aim of this study is to present the improvement of outcome measures of this program, comparing the results of two groups of newborns screened successively.
Methods:
We analyzed data from two groups of full-term newborns screened at our setting. The first group included all newborns born and screened during the initial 3 years of application of the program and the second group included all newborns born and screened during the next 2 years. TEOAEs were performed during the first days after birth. All newborns who failed the initial test underwent repeat testing with TEOAEs before hospital discharge. Newborns with absence of otoacoustic emissions were referred to follow-up test after 1 month. Results were compared between the two groups.
Results:
The first group included 22,195 newborns-examined during 3 years and the second group included 25,032 newborns-examined during 2 years, due to reduction of the rate of newborns who missed screening. Refer rate was 3.1% for the first group and 2.1% for the second group. "Missed to follow-up" rate was reduced from 72.2% in the first group to 58.2% in the second group.
Conclusions:
The rate of newborns who did not undergo screening and the rate of "missed to follow-up" newborns were reduced in time, due to various modifications of the protocol. Universal newborn hearing screening may be, thus, a feasible and cost effective method of identifying congenital hearing loss.
