The outcome of a study on hearing loss in graduates of one third-level and two second-level intensive care nurseries (ICN) is reported. The goals were to identify, test, and fit hearing aids on those who need them. Initial hearing-threshold estimates were obtained by auditory brainstem response (ABR) analyses at the time of discharge from the hospital; the mean percentage of failures to respond to 30-dB nHL clicks (in one or both ears) was 19.8 percent for the third-level ICN graduates (N = 4374), and 12.0 percent for the second-level graduates (N = 1527). About half of those with hearing loss at the initial Test were returned for a ReTest 6-20 weeks later, at which time 48.7 percent of the third-level and 44.0 percent of the second-level group were judged normal because they delivered 25-dB click ABRs bilaterally. Following conventional audiological work-ups of the ones with unilateral or bilateral hearing loss, hearing aids were fitted to 92 in the third-level group (2.1% of those Tested) and 22 of the second-level group (1.4%). Not quite half of these fittings occurred within 1 year of the hospital Test that initially diagnosed the loss.
报告了一项针对一家三级和两家二级重症监护病房（ICN）毕业生听力损失的研究结果。目标是为有需要的人识别、测试并佩戴助听器。出院时通过听觉脑干反应（ABR）分析获得初始听力阈值估计值；三级ICN毕业生（N = 4374）对30 dB nHL短声（单耳或双耳）无反应的平均百分比为19.8%，二级毕业生（N = 1527）为12.0%。约一半在初次测试时有听力损失的人在6 - 20周后返回进行复测，此时三级组48.7%和二级组44.0%被判定为正常，因为他们双侧引出了25 dB短声ABR。在对单侧或双侧听力损失者进行常规听力学检查后，三级组有92人佩戴了助听器（占测试者的2.1%），二级组有22人（占1.4%）。这些佩戴助听器的情况中，不到一半发生在最初诊断出听力损失的医院测试后的1年内。
