This is a systematic review of the peer- and non-peer-reviewed published literature investigating the effectiveness of using a risk-factor registry for targeted surveillance to identify hearing loss after the newborn hearing screen.
- What risk factors are being used to determine referral for assessment of postnatal hearing loss?
- What are the referral rates for monitoring assessments for postnatal hearing loss in infants?
- What is the relationship between risk factors for postnatal hearing loss and diagnostic findings from monitoring assessments?
- Are there any other protocols or approaches available that are more accurate, efficient, and cost-effective than the use of risk-factor registries?
Children identified with permanent bilateral or unilateral hearing loss after passing the hearing screening or assessment at birth.
Targeted surveillance based on hearing loss risk factors.
Number of Studies Included:
Permanent Childhood Hearing Loss
- Risk Factors/Surveillance
- Among risk-factor registries, the most commonly used risk factors included: gestational age (GA), low birthweight (LBW), craniofacial anomalies, respirator support, aminoglycoside use, and TORCH infections (Toxoplasmosis, other infections, Rubella, Cytomegalovirus [CMV], and Herpes simplex virus).
- Risk factors strongly associated with hearing loss were: CMV, extracorporeal membrane oxygenation (ECMO), congenital diaphragmatic hernia, and persistent pulmonary hypertension of the newborn (PPHN).
- Risk factors with limited or no association with hearing loss included LBW, preauricular skin tags and ear pits(PSEP), neonatal toxoplasmosis.
- No studies comparing risk-factor registries to alternative protocols for detecting postnatal hearing loss were found.
