Preoperative factors influencing the rate and speed of available communication ability in prelingual paediatric cochlear implantation recipients

Abstract

Background

Few studies have assessed factors influencing the rate and speed of good outcomes in cochlear implantation (CI) children.

Objective

To analyse the factors influencing the rate and speed of available communication in CI children.

Material and Methods

The study involved 316 children. The categories of auditory performance (CAP) and speech intelligibility rating (SIR) were used to evaluate outcomes. Multivariable proportional Cox regression models were established to analyse the effect of preoperative factors.

Results

Five variables were entered into the three multivariable models of CAP ≥6, SIR ≥4 and concurrent CAP ≥6 and SIR ≥4. Older age at implantation was a significant poor factor in the three models with estimated hazard ratios (HRs) of .541, .629, and .554, respectively. Another negative factor was poor parental literacy for the three outcomes (HR .639, .638, and .542, respectively). More than 3 months of rehabilitation from institutes had a positive effect on CAP ≥6 and concurrent CAP ≥6 and SIR ≥4 (HR 1.626 and 1.667, respectively).

Conclusions and Significance

Older age at implantation and poor parental literacy were negative factors. Receiving regular rehabilitation from institutes pre-CI could help the children gain available communication ability earlier on.

Chinese Abstract

背景：很少有研究评估人工耳蜗植入 (CI) 儿童的良好结果等级和速度的影响因素。

目的：分析影响 CI儿童 的可用交流等级和速度的因素。

材料和方法：该研究涉及 316 名儿童。 使用听觉表现类别 (CAP)和语音清晰度等级 (SIR) 进行评估结果。 建立多变量比例 Cox回归模型来分析术前因素的影响。

结果：5个变量输入3个多变量模型CAP≥6、SIR≥4和并发 CAP ≥ 6 和 SIR ≥ 4。 植入时年龄较大是这三个模型的一个显著不良因素, 估计风险比 (HR) 分别为 .541、.629 和 .554。三种结果（分别为 HR 0.639、0.638 和0.542）的另一个不利因素为父母识字率低。 3 个多月的机构康复对 CAP ≥ 6 和并发 CAP ≥ 6 和SIR ≥ 4 具有正面影响（分别为 HR 1.626 和 1.667）。

结论和意义：植入时年龄较大和父母文化程度低是负面因素。 在 CI 植入前接受机构的定期康复训练可以较早地帮助孩子们获得可用交流能力。
