Summary

High-risk factors in intensive care nursery graduates don't equally predict hearing outcomes. Universal auditory screening may be more effective for identifying hearing loss in these infants.

Neonatal care
Audiology
Developmental pediatrics

Background:

Graduates of intensive care nurseries are at increased risk for hearing impairment.
Auditory brain-stem response (ABR) testing is a key diagnostic tool for assessing hearing in infants.
Identifying specific risk factors for hearing loss is crucial for targeted interventions.

Purpose of the Study:

To investigate the association between various high-risk factors and auditory brain-stem response (ABR) outcomes in intensive care nursery graduates.
To determine if factors on the high-risk register have differential predictive value for hearing impairment.
To evaluate the effectiveness of targeted screening versus universal screening for hearing loss in this population.

Main Methods:

A cohort of 1240 graduates from an intensive care nursery underwent auditory brain-stem response (ABR) testing.
Univariate analysis using chi-squared and Fisher's Exact Test was employed.
Stepwise logistic regression was utilized to identify significant predictors of ABR outcomes.

Main Results:

The study found that not all factors included in the high-risk register carried equal weight in predicting auditory brain-stem response outcomes.
Certain risk factors were more strongly associated with abnormal ABR results than others.
The predictive power of individual high-risk factors varied significantly.

Conclusions:

The findings suggest that relying solely on traditional high-risk registers may not be sufficient for comprehensive hearing screening in intensive care nursery graduates.
Universal auditory screening in the intensive care nursery setting may offer a more equitable and effective approach to detecting hearing deficits.
Revising screening protocols to include universal testing could improve early identification and management of hearing loss in vulnerable infant populations.
