The value of anthropometric and biochemical indices in predicting short-term mortality among patients in general medical wards was assessed in 294 patients admitted consecutively to a district hospital over a one month period. Using a stepwise logistic regression model and supported by the linear discriminant analysis method, mortality within 3 months could be predicted with sensitivity of 83% and specificity of 84% using the following variables: sex, functional ability, urea, total protein, alkaline phosphatase and albumin-adjusted calcium. Addition of anthropometric values and biochemical nutritional indices did little to improve the accuracy of the prediction, contrary to previous findings among surgical patients and elderly residents of long-term care institutions.
在一个月的时间里,对一家地区医院连续收治的294例普通内科病房患者进行了评估,以确定人体测量和生化指标在预测短期死亡率方面的价值。采用逐步逻辑回归模型,并在线性判别分析方法的支持下,使用以下变量可预测3个月内的死亡率,灵敏度为83%,特异度为84%:性别、功能能力、尿素、总蛋白、碱性磷酸酶和白蛋白校正钙。与先前在外科患者和长期护理机构老年居民中的研究结果相反,增加人体测量值和生化营养指标对提高预测准确性作用不大。
