In this second article in the quality improvement (QI) methods series, we discuss how data are best displayed and analyzed in QI projects while focusing on some similarities with and differences from traditional clinical research. We demonstrate why displaying data over time on a run or control chart is superior to using pre-post analysis for QI studies. We introduce several types of statistical process control charts for data commonly collected during QI programs and provide guidance on how to use the proper chart. Last, we present solutions to several common data challenges in QI projects.
在这篇质量改进（QI）方法系列的第二篇文章中，我们讨论了在 QI 项目中如何最好地展示和分析数据，同时重点介绍了与传统临床研究的一些相似之处和不同之处。我们展示了为什么在 QI 研究中，随着时间的推移在运行或控制图上显示数据优于使用前后分析。我们介绍了几种在 QI 计划中常见的数据统计过程控制图，并提供了如何使用正确图表的指导。最后，我们提出了 QI 项目中几个常见数据挑战的解决方案。
