Screening audiometry using the high-risk register in a level III nursery.

Several factors, including those in the high-risk register, were studied in 1240 graduates of an intensive care nursery who underwent auditory brain-stem response testing. Univariate analysis, with chi 2 and Fisher's Exact Test, and stepwise logistic regression were used to identify variables associated with auditory brain-stem response outcomes. Results suggest that factors in the high-risk register do not carry equal weight and that universal screening in the intensive care nursery may be preferable.
