Case Study #2: John


John was born premature and was a graduate of the UW Medical Center NICU (neonatal intensive care unit). John was born at 25 weeks gestation, 685 grams. His neonatal course was significant for chronic lung disease treated with extended ventilation for 4 weeks, grade II intraventricular hemorrhage, and stage II retinopathy of prematurity. John did not pass his neonatal BAER newborn hearing screening.



John was seen in the Pediatric Audiology Clinic at CHDD at 3 weeks corrected age for a comprehensive evaluation using the BAER, OAE and tympanometry tests. Testing determined that John had a severe sensorineural hearing loss in both ears. His parents were counseled regarding the impact of a significant hearing loss and recommendations for treatment, including hearing aids and early intervention.

Physical therapy

Due to his extreme prematurity, John was followed by the High Risk Infant Follow-up Clinic to monitor his development. A physical therapy evaluation at 4 months corrected age showed that John was developing appropriately in both his motor and mental skills.


As part of the High Risk clinic, John had a developmental assessment at 12 and 24 months corrected age that showed that he was at age level for his cognitive skills.


John was diagnosed with a bilateral severe sensorineural hearing loss shortly after his discharge from the hospital. The etiology of his hearing loss is likely associated with his severe prematurity. Newborn hearing screening, early fitting of hearing aids, and enrollment in an early intervention program are all factors in John’s development.



John returned in one month for fitting with binaural hearing aids and the audiologist assisted the family in evaluating the early intervention services available in their community. By 3 months of age, John and his family were enrolled in an early intervention program, receiving weekly home visits. When John graduated from the program at age 3, he was at age-level for his language skills.
