Abstract: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.
