Newborn hearing screening using the Crib-O-Gram
Insights
Crib-O-Gram hearing screenings in infants did not show associations between test outcomes and factors like gestational age or weight. However, infants who failed both screenings had shorter test durations than those who passed initially.
Area of Science:
- Neonatal care
- Audiology
- Pediatric screening
Background:
- Neonatal intensive care unit (NICU) graduates require hearing screenings.
- The Crib-O-Gram is a common tool for infant hearing assessment.
- Understanding factors influencing screening outcomes is crucial for efficient audiological care.
Purpose of the Study:
- To identify variables affecting the failure rate of Crib-O-Gram hearing screenings.
- To determine factors influencing the duration of Crib-O-Gram tests.
- To analyze the relationship between infant characteristics and screening results.
Main Methods:
- Screening of 163 infants who graduated from a NICU.
- Categorization of infants into three groups based on screening outcomes (pass first, fail-pass, fail-fail).
- Statistical analysis to correlate screening duration and outcome with gestational age, conceptional age, weight, and test start time.
Main Results:
- No association found between Crib-O-Gram screening outcome/duration and gestational age, conceptional age, weight, or time of test commencement.
- Infants who failed both screenings (Group C) exhibited significantly shorter screening durations compared to infants who passed the first screening (Group A).
Conclusions:
- Infant characteristics like gestational age and weight do not appear to influence Crib-O-Gram screening success or duration.
- Shorter screening times in infants who failed twice may indicate specific physiological or behavioral factors requiring further investigation.
- Optimizing hearing screening protocols for NICU graduates may benefit from considering these findings.
Abstract:
The purpose of this investigation was to identify variables that might affect the failure rate and test duration of Crib-O-Gram hearing screenings. One hundred sixty-three infants who graduated from a neonatal intensive care unit were screened. All screenings were performed by nurses in the open nursery. For the purposes of statistical analyses the infants were divided into three groups: group A--passed the first screening; group B--failed the first screening and passed the second screening; and group C--failed both screenings. The length of Crib-O-Gram screening and screening outcome were not associated with gestational age, conceptional age, weight, or time at which the test commenced. Infants who failed the screening twice had shorter screening durations than infants who passed the screening the first time.
