Screening audiometry using the high-risk register in a level III nursery.

Area of Science:

• 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.
