本文详细介绍了一个面向时间的临床数据库的原理和实现,以及一个以图形、插图和散点图的形式显示个体患者数据的程序。本文提出了一种高效的图形存储数据结构,其中多个变量的曲线图是重叠的。显示程序允许按访问或按时间绘制患者数据、伸缩时间轴以及改变显示大小。同时发生的临床事件的线条图可以在图表下方对齐。不需要特殊的图形设备。讨论了数据表示、转换和显示布局等问题。
This paper details the principles and implementation of a time-oriented clinical database and a program for displaying data on individual patients as graphs, line drawings of episodes and scatter diagrams. The article presents efficient data structures for storage of graphs in which plots of multiple variables are overlayed. The display program permits plotting of patient data either by visit or by time, telescoping of the time axis, and changing of the display size. Line drawings of concurrent clinical episodes may be aligned beneath the graphs. No special graphics equipment is required. Issues of data representation, transformation, and display layout are discussed.
