To assess whether hearing aids improve the quality of life of elderly persons with hearing loss.
Primary care clinics at a Bureau of Veterans Affairs hospital.
One hundred and ninety-four elderly veterans who were identified as being hearing impaired from a screening survey involving 771 consecutive clinic patients. Of the original 194, 188 (97%) completed the trial.
Subjects were randomly assigned to either receive a hearing aid (n = 95) or join a waiting list (n = 99). MAIN ENDPOINTS: A comprehensive battery of disease-specific and generic quality-of-life measures were administered at baseline, 6 weeks, and 4 months.
Persons assigned to the two groups were similar in age, ethnicity, education, marital status, occupation, and comorbid diseases. At baseline, 82% of subjects reported adverse effects on quality of life due to hearing impairment, and 24% were depressed. At follow-up, a significant change in score improvements for social and emotional function (34.0; 95% CI, 27.3 to 40.8; P less than 0.0001), communication function (24.2; CI, 17.2 to 31.2; P less than 0.0001), cognitive function (0.28; CI, 0.08 to 0.48; P = 0.008), and depression (0.80; CI, 0.09 to 1.51; P = 0.03) was seen in subjects who received hearing aids compared with those assigned to the waiting list. Six drop-outs (three per group), no crossovers, and no significant changes in cointerventions were seen. Average, self-reported, daily aid use in the hearing aid group was 8 hours.
Hearing loss is associated with important adverse effects on the quality of life of elderly persons, effects which are reversible with hearing aids.
评估助听器是否能改善老年听力损失患者的生活质量。
一所退伍军人事务部医院的基层医疗诊所。
在一项对771名连续就诊患者进行的筛查调查中，被确定为听力受损的194名老年退伍军人。最初的194名患者中，188名（97%）完成了试验。
受试者被随机分为两组，一组接受助听器（n = 95），另一组加入等候名单（n = 99）。主要终点指标：在基线、6周和4个月时，对一系列全面的特定疾病和通用生活质量指标进行测量。
两组受试者在年龄、种族、教育程度、婚姻状况、职业和合并疾病方面相似。基线时，82%的受试者报告听力障碍对生活质量有不良影响，24%的受试者有抑郁情绪。随访时，与等候名单组相比，接受助听器的受试者在社会和情感功能（得分改善34.0；95%可信区间，27.3至40.8；P < 0.0001）、沟通功能（24.2；可信区间，17.2至31.2；P < 0.0001）、认知功能（0.28；可信区间，0.08至0.48；P = 0.008）和抑郁（0.80；可信区间，0.09至1.51；P = 0.03）方面有显著的得分改善。有6名受试者退出（每组3名），没有交叉情况，共同干预措施也没有显著变化。助听器组受试者自我报告的平均每日使用时长为8小时。
听力损失对老年人的生活质量有重要不良影响，而助听器可使其逆转。
