Abstract

OBJECTIVE

This paper introduces a model that predicts future changes in systolic blood pressure (SBP) based on structured and unstructured (text-based) information from longitudinal clinical records.

METHOD

For each patient, the clinical records are sorted in chronological order and SBP measurements are extracted from them. The model predicts future changes in SBP based on the preceding clinical notes. This is accomplished using least median squares regression on salient features found using a feature selection algorithm.

RESULTS

Using the prediction model, a correlation coefficient of 0.47 is achieved on unseen test data (p<.0001). This is in contrast to a baseline correlation coefficient of 0.39.

摘要

目的

本文介绍了一种基于纵向临床记录中的结构化和非结构化(基于文本)信息来预测收缩压(SBP)未来变化的模型。

方法

对于每位患者,将临床记录按时间顺序排序,并从中提取SBP测量值。该模型基于先前的临床记录来预测SBP的未来变化。这是通过对使用特征选择算法找到的显著特征进行最小中位数平方回归来实现的。

结果

使用该预测模型,在未见过的测试数据上实现了0.47的相关系数(p<0.0001)。这与0.39的基线相关系数形成对比。
