“…Initial database searches identified 6964 potential articles with 18 included in the review (Figure 1). Of these, 11 focused on diagnostic methods and schedules (Table 1), [35][36][37][38][39][40][41][42][43][44][45] 4 investigated the impact of cerebral palsy on hearing loss assessment and diagnosis, [46][47][48][49] and 3 reported on intervention or rehabilitation for infants with or at high risk for cerebral palsy. [50][51][52] Sample size ranged from 13 to 40 723 infants.…”

“…Threshold cutoff for diagnosing hearing impairment varied across studies, from 25 to 40 dB normal hearing level or electrophysiologic level (nHL) (electrophysiologic thresholds). Degree of hearing impairment varied, with some authors reporting on moderate to profound hearing loss, 37,39,42,44 whereas others included all impairments, even potential ones 40,43,45,47,48 (Table 1). Overall, risk of bias in this category was low, with most studies providing appropriate level of detail in protocol, outcome measures, and analysis descriptions.…”

Hearing Loss Diagnosis and Early Hearing-Related Interventions in Infants With or at High Risk for Cerebral Palsy: A Systematic Review

Aim: To synthesize published evidence regarding hearing impairment diagnosis and interventions in infants with or at high risk for cerebral palsy in the first year after birth. Method: Nine databases were searched for MeSH terms up to February 2020. Included studies were published in English, enrolled infants with or at high risk for cerebral palsy, and addressed hearing evaluation/rehabilitation within the first year after birth. Quality of evidence was evaluated using RTI Item Bank and QUADAS-2. Results: Eighteen articles met inclusion criteria. Quality of the evidence ranged from low to high, revealing variability in diagnostic assessment methodologies and adherence to diagnostic schedules. Concerns for bias included lack of recognition of cerebral palsy effects and etiologies on functional hearing assessment methods and results. Two interventions (hearing aid and cochlear implantation) were identified; however, reported use was inconsistent. Interpretation: Hearing screening in infants with or at high risk for cerebral palsy requires evaluation of the entire auditory pathway preferentially using comprehensive electrophysiological panels of assessments. For infants with perinatal neural insults, pediatric neurologists are uniquely positioned to recommend adherence to systematic surveillance and comprehensive audiology assessments, regardless of comorbidities and motor impairments.

“…In NICHD Phototherapy Trial, rates of bilateral hearing impairment with amplification were 1% in the aggressive phototherapy arm and 3% in the conservative phototherapy arm ( 12 ). In a Canadian study of preterm infants ≤800 g, the overall rate of bilateral permanent HL was 9% (50/586 infants) ( 13 ) and rates of permanent bilateral hearing loss were higher at lower gestational age ( 14 ). Based on these estimates of prevalence, hearing impairment would be the third most prevalent major developmental impairment identifiable during infancy among extremely low birth weight infants after cognitive impairment and cerebral palsy ( 15 ).…”

Objective: To evaluate whether treated hypotension in the first 24 postnatal hours is associated with hearing loss in extremely low birth weight (ELBW) infants. Study Design: In a cohort of 735 ELBW infants, we identified 25 with sensorineural hearing loss at 12–24 months adjusted age. For each case we selected 3 controls with normal hearing. Logistic regression models were used to adjust for confounding variables. Results: 60% of cases and 25% of controls were treated for hypotension. After adjusting for confounding variables (gestational age, antenatal glucocorticoids, 5 minute Apgar < 6, insertion of an umbilical catheter, treatment with high frequency ventilation, and major cranial ultrasound abnormality), treated hypotension was associated with an increased risk of sensorineural hearing loss (adjusted odds ratio: 3.6; 95% confidence interval: 1.3–9.7). Conclusions: Treated hypotension in ELBW infants in the first 24 hours of life is associated with an increased risk of sensorineural hearing loss.

“…As these infants are identified as being at-risk for progressive or late-onset hearing loss, it is essential that they are not only screened at birth, but are followed regularly for audiological assessment and are not lost to follow-up. [7] The High-Risk Register Use of the HRR as the primary indicator for screening of newborns for hearing loss was inadequate. In 1999, Finitzio and Crumley reported that, according to the identification rates currently reported from widespread screening programs, approximately 8,000-16,000 newborns are born with hearing loss each year.…”

Universal screening programs have been implemented across the United States. Hearing loss occurs often enough in the general population to justify the legislation for universal hearing screening programs across the United States. http://emedicine.medscape.com/article/836646-overview not suspect a hearing loss until the age of 2-3 years, after important speech and language milestones have not been met. By the time these milestones are missed, the hearing-impaired child has already experienced irreversible delays in speech and language development.

Incidence and pattern of hearing impairment in children with ≤ 800 g birthweight in British Columbia, Canada

Abstract: The incidence and severity of hearing impairment in a cohort of extremely low-birthweight children increased significantly from 5% to 13% (p = 0.01) over a 24-year period. Comorbidities were common. Potentially modifiable causes are explored.
