本文应用逐步判别分析法对重危型肾综合征出血热预后判断进行了研究。筛选出影响因素７个，建立判别函数，应用实际资料进行回顾性和前瞻性考核，判别符合率分别为９６．０８％及９５．４５％，判别精度高，实际应用效果好，值得推广。对于判别函数的应用，不仅仅局限于对该病预后的判断，尚可通过对单一病人的定期检查计算，动态观察病势的发展变化及转归过程，为定量准确分析重危型肾综合征出血热的预后提供了科学依据。
In this paper, step by step discriminant analysis of critical risk of hemorrhagic fever with renal syndrome prognosis were studied. Seven influential factors were screened, and a discriminant function was established. The actual data were used for retrospective and prospective assessment. The coincidence rates were 96.08% and 95.45% respectively. The discriminant accuracy was high, and the practical application effect was good and worthy of promotion. For the application of the discriminant function, not only limited to the prognosis of the disease, but also through the regular examination of a single patient, the dynamic observation of the development and changes in disease progression and the outcome of the process for the quantitative and accurate analysis of critically ill patients with renal syndrome bleeding Hot prognosis provides a scientific basis.
