本文采用Kappa统计和相关分析方法估计194对恶性肿瘤患者与其亲属(代理者)提供关于病例过去暴露信息的一致度,以探讨亲属提供信息的真实性。结果表明:亲属提供的关于患者的年龄、文化程度、吸烟、饮酒、饮茶,家族患癌史等信息的真实性好。对某些个人嗜好如喜欢甜食、喜酸辣等,毒物接触史以及慢性病史,真实性尚可。而对精神刺激史、食物摄入的估计以及一些急性污染病史,真实性差。配偶作为代理者提供的信息较子女提供的信息真实性好。
In this paper, we use Kappa statistics and correlation analysis to estimate the consistency of 194 patients with malignant tumors and their relatives (agents) in providing information about the past exposure of cases so as to explore the authenticity of the information provided by relatives. The results showed that relatives provided good information about the patient’s age, educational level, smoking, drinking, drinking tea, family history of cancer and other information. For some personal hobby like sweet food, likes hot and sour, poison history of exposure and chronic medical history, authenticity is acceptable. However, the history of mental stimulation, food intake estimates and some acute pollution history, poor authenticity. The information provided by the spouse as an agent is more authentic than the information provided by the child.
