铀矿矽肺预后分析

为了解铀矿工矽肺生存情况的规律与特点，对铀矿工矽肺预后进行预测。利用单因素方法，结合寿命表法、Ｋａｐｌａｎ－Ｍｅｉｅｒ法及分层Ｃｏｘ回归法对部分铀矿和铀矿地质勘探队的铀矿矽肺病例预后进行综合分析研究。结果为铀矿和铀矿地质勘探队的铀矿矽肺病例的病死率差别有高度性，影响铀矿矽肺病例预后的主要因素为铀矿接尘工龄、工种、是否并发肺结核及初次诊断为矽肺病的期次。利用生存概率与预后指数关系曲线可对铀矿矽肺病例

Prognosis Study on Silicosis in Uranium Mines

To understand the regularity and characteristics of survival of silicotic patients and topredict their prognosis in uranium mines, a comprehensive prognosis study was carried out by singlefactor method, life-table method, Kaplan-Meter method and stratified Cox regression method inseveral uranium mines and geological prospecting teams for uranium mines. The difference of casefatalities between uranium mines and geological prospecting teams for uranium mines was significant.The length of time exposed to uranium dust, the type of work in production, whether complicatedwith tuberculosis or not and the stage of silicosis diagnosed at the first time were main factors affectingthe prognosis. Prognosis of patients suffering from silicosis could be predicted with survivalprobability vs prognosis index curves.
