摘　　要：目的病案随机抽查是病案管理工作的重要步骤之一,本文系统介绍运用SAS软件快速获得准确反应整体情况的病案随机样本的方法。方法以国际权威的统计分析软件SAS为运行环境,介绍病案数据的导入以及运用surveyselect过程实现随机抽样的方法,提供了病案管理工作中常用简单随机抽样和分层随机抽样(含单个分层因素、多个分层因素2种情况)的SAS程序。结果相较于运用随机数字表、Excel函数或建立在主观意志上的随机抽样,借助于SAS软件实施病案管理库中的随机抽样效率高,提升了病案管理工作中随机抽样的规范性和科学性。结论在日常的病案管理工作中纳入SAS软件随机抽样方便快捷,值得广大病案管理工作者参考使用。Objective Random sampling of medical records is one of the important work in medical records management.This paper systematically introduces the method of using SAS software to quickly obtain the random samples of medical records which reflect the overall situation accurately.Methods This paper takes the international authoritative statistical analysis software(SAS)for running environment,introducing the importing of medical record data and the applying of the surveyselect process to the random sampling systematically,and also providing the SAS program which is commonly used in both simple and stratified random sampling(including single layer and multiple layer).Results Compared with the random number table,Excel function or random sampling based on subjective will,the random sampling using SAS software is of higher efficiency,which improves the standardization and the scientificity of random sampling in medical record management.Conclusion Using SAS software for random sampling in daily medical record management is convenient and efficient,therefore is worthy of reference and widespread use by the majority of medical record management workers.
