To compare hearing screening results using pure tones and distortion product otoacoustic emissions (DPOAEs) with nursing home residents who have dementia and explore the relationship of hearing impairment and cognitive function using the Mini- Mental Status Evaluation (MMSE).
A correlational design was implemented to evaluate residents in a large inner city nursing home.
One hundred one nursing home residents 65-108 years.
DPOAEs and pure tone screenings were conducted at 30 dB HL and 40 dB HL at 1, 2, and 3 kHz. Pure tone thresholds at 1, 2, and 3 kHz were obtained. The MMSE was administered to all participants.
Results showed that all residents failed the DPOAE screen, 97.1% failed at 30 dB HL, and 90.0% failed at 40 dB HL. Kendall's tau, phi correlation, linear by linear association, and χ(2) results indicated no significant relationship for any of the screening protocols and cognitive status other than a significant finding with left ear screening at 40 dB HL. Logistic regression analysis indicated that individuals who passed the screen had better MMSE scores. Results of the t test and Mann-Whitney U test revealed a significant difference in cognitive function for residents with a mild hearing loss compared with those with a more significant hearing loss.
For screening nursing home residents, 40 dB HL screening level or DPOAEs can be used. The significant finding that residents with greater than a mild hearing loss have poorer cognitive function reinforces the importance of identifying residents with a hearing loss and providing rehabilitation and follow-up.
比较使用纯音和畸变产物耳声发射（DPOAE）对患有痴呆症的养老院居民进行听力筛查的结果，并使用简易精神状态评价量表（MMSE）探索听力损伤与认知功能的关系。
采用相关性设计评估大型市内养老院的居民。
101 名年龄在 65-108 岁的养老院居民。
在 30dB HL 和 40dB HL 下，在 1、2 和 3kHz 频率处进行 DPOAE 和纯音筛查。在 1、2 和 3kHz 频率处获得纯音阈值。对所有参与者进行 MMSE 测试。
结果显示，所有居民均未通过 DPOAE 筛查，97.1%在 30dB HL 下未通过，90.0%在 40dB HL 下未通过。Kendall's tau、phi 相关、线性线性关联和 χ(2)结果表明，除了在 40dB HL 下左耳筛查存在显著关联外，任何筛查方案与认知状态之间均无显著关系。逻辑回归分析表明，通过筛查的个体具有更好的 MMSE 评分。t 检验和 Mann-Whitney U 检验的结果表明，与听力损失程度更严重的居民相比，轻度听力损失居民的认知功能存在显著差异。
对于养老院居民的筛查，可以使用 40dB HL 筛查水平或 DPOAE。听力损失程度更大的居民认知功能更差的这一显著发现，强调了识别听力损失居民并提供康复和随访的重要性。
