目的：研究设计：采用听觉功能分类调查表对98名儿童进行听觉功能测试。所有数据均前瞻性收集。用于解释听觉表现类别中增益的变量是植入时的年龄。性别、“未治疗”耳聋的持续时间。植入发生的年份、卫生保健投入和听力损伤的原因。结果：听觉表现类别的增益与植入年龄呈负相关，即植入发生的年份。以及孩子接受的医疗咨询次数。其他变量都没有显着的决定因素，在听觉Performance.Conclusion类增益：本研究表明，检查增量增益植入，而不是简单地检查结果水平的价值。研究发现，小儿植入术的收益递减。这表明，只有在经过仔细考虑后，才应进一步放宽植入计划的准入标准。该研究还证实，植入时的年龄是结局的重要决定因素。在较年轻时接受植入的患者在听觉表现类别中获得更大的增益。这一发现对筛查以及植入服务的购买者和提供者都有影响，强调了及时响应已确定需求的重要性。
Objective: To investigate variations in gains in auditory performance in children with cochlear implants.Study Design: The auditory performance of 98 children was measured with the Category of Auditory Performance survey instrument. All data were collected prospectively. Variables used to explain gain in Category of Auditory Performance were age at implantation. sex, the duration of "untreated" deafness. the year in which implantation occurred, health care inputs, and cause of hearing impairment. The data were analyzed by ordered probabilistic regression analysis.Results: Gain in Category of Auditory Performance was observed to be negatively related to age at implantation, the year in which implantation took place. and the number of medical consultations the child received. None of the other variables were significant determinants of gain in Category of Auditory Performance.Conclusion: This study demonstrates the value of examining incremental gain from implantation rather than simply examining outcome levels. It was found that pediatric implantation is subject to diminishing returns. This suggests that further relaxation of entry criteria to implant programs should be undertaken only after careful consideration. The study also confirmed that age at implantation is an important determinant of outcomes. Greater gain in Category of Auditory Performance was experienced by those who underwent implantation at a younger age. This finding has implications for screening, as well as for purchasers and providers of implant services, highlighting the importance of responding in a timely fashion to identified need.
