Although one potential benefit of electronic information systems is the opportunity for secondary use of data, it is often challenging in practice to reuse data. We identify challenges to the secondary use of electronic data from a web-based project management system, and trace these challenges to their root causes. Data quality issues arose from: differential incentives for integrity of different data; software flexibility that allowed a single task to be documented in multiple ways; variability in documentation practices; variability in use of standardized vocabulary; and changes in project procedures and system configuration over time. These issues are very similar to the issues that pose challenges for secondary uses of clinical and operational data for research, public health, and quality improvement. We conclude that secondary use of operational data requires an in-depth understanding of the primary workflow processes that produced the data, as these processes lead to data integrity issues.
尽管电子信息系统的一个潜在好处是有机会对数据进行二次使用，但在实践中对数据进行再利用往往具有挑战性。我们识别了来自基于网络的项目管理系统的电子数据二次使用所面临的挑战，并将这些挑战追溯到其根本原因。数据质量问题源于：对不同数据完整性的不同激励措施；软件的灵活性使得单个任务可以通过多种方式记录；文档记录实践的差异；标准化词汇使用的差异；以及项目程序和系统配置随时间的变化。这些问题与那些给临床和运营数据用于研究、公共卫生及质量改进的二次使用带来挑战的问题非常相似。我们得出结论，运营数据的二次使用需要深入了解产生数据的主要工作流程，因为这些流程会导致数据完整性问题。
