Four factors that accurately predict hearing loss in "high risk" neonates.
Two simple overall measures of health--length of stay in the Intensive Care Nursery (ICN) and gestational age--predict hearing loss in ICN graduates. Craniofacial anomalies, congenital perinatal infections, and meconium aspiration are strong predictors of hearing loss, especially in term infants. Findings are based on univariate and multivariate analyses of a number of variables that might be associated with permanent hearing loss. Study variables included all seven High Risk Register items and a number of other features of the ICN history. They were examined in 799 ICN graduates whose hearing had been monitored in their first few years of life. These babies composed 40% of the ICN population and were selected because they had one or more "high risk" factors in their neonatal history. Prevalence of hearing loss in this high risk sample was similar to that found in other ICN samples. Prevalence of hearing loss associated with individual Risk Register items was similar to other published findings for some items and not for others.
