AIMS
To evaluate a postal questionnaire designed to identify elderly persons in need of geriatric evaluation and intervention in the community.
METHODS
A sample of elderly persons, over 75 years, was randomly selected from the age-sex register of four general practices in the Auckland area. All respondents filled out postal questionnaires and a blinded assessment was made in their own homes using validated geriatric assessment tools (the reference test). Objective evaluations were compared to self report questionnaire results and sensitivity, specificity, positive and negative predictive values were calculated.
RESULTS
Sixty-four persons aged 75-93 were evaluated. Thirty-nine subjects (61%) answered the questionnaire in a way which indicated they had one or more unmet needs. Reference test evaluations showed that 23 persons (36%) had problems in one or more areas. Sensitivity for the questionnaire was 0.78 (18/23 correctly identified) and specificity was 0.49. Positive and negative predictive values were 46% and 80% respectively.
CONCLUSIONS
A postal questionnaire may be a useful adjunct to health surveillance of the elderly in general practice in New Zealand.
目的
评估一份邮政调查问卷，该问卷旨在识别社区中需要进行老年医学评估和干预的老年人。
方法
从奥克兰地区四个全科医疗诊所的年龄性别登记册中随机抽取75岁以上的老年人样本。所有受访者填写邮政调查问卷，并使用经过验证的老年医学评估工具（参考测试）在其家中进行盲法评估。将客观评估结果与自我报告问卷结果进行比较，并计算敏感性、特异性、阳性预测值和阴性预测值。
结果
对64名年龄在75 - 93岁之间的人进行了评估。39名受试者（61%）回答问卷的方式表明他们有一项或多项未满足的需求。参考测试评估显示，23人（36%）在一个或多个领域存在问题。问卷的敏感性为0.78（正确识别18/23），特异性为0.49。阳性预测值和阴性预测值分别为46%和80%。
结论
邮政调查问卷可能是新西兰全科医疗中老年人健康监测的有用辅助工具。
