保持数据质量和完整性对于涉及前瞻性数据收集的研究非常重要。必须输入数据,必须识别错误或缺失的数据并在可能的情况下进行纠正,并创建稽查跟踪。作为一个例子,一个大型的前瞻性研究,密苏里州下呼吸道感染(LRI)项目,我们提出了一种方法,主要使用SAS软件的数据管理。密苏里州LRI项目是一项前瞻性队列研究的养老院居民谁开发了LRI。招募受试者,收集数据,并进行三年以上的随访。收集了20种不同形式的数据。对表格进行目视检查,并将其发送至场外进行数据输入。使用SAS软件读取输入的数据文件,检查潜在错误,对数据集进行校正,并将联合收割机批次合并为分析数据集。描述了数据管理程序。研究数据收集导致超过20,000份完整的表格。数据管理是成功的,产生了干净的,内部一致的数据集进行分析。数据管理所需的时间被大大低估。前瞻性研究的数据管理应在数据收集之前进行规划。数据输入和检查的持续过程可以及时恢复错误和丢失的数据。
Maintaining data quality and integrity is important for research studies involving prospective data collection. Data must be entered, erroneous or missing data must be identified and corrected if possible, and an audit trail created. Using as an example a large prospective study, the Missouri Lower Respiratory Infection (LRI) Project, we present an approach to data management predominantly using SAS software. The Missouri LRI Project was a prospective cohort study of nursing home residents who developed an LRI. Subjects were enrolled, data collected, and follow-ups occurred for over three years. Data were collected on twenty different forms. Forms were inspected visually and sent off-site for data entry. SAS software was used to read the entered data files, check for potential errors, apply corrections to data sets, and combine batches into analytic data sets. The data management procedures are described. Study data collection resulted in over 20,000 completed forms. Data management was successful, resulting in clean, internally consistent data sets for analysis. The amount of time required for data management was substantially underestimated. Data management for prospective studies should be planned well in advance of data collection. An ongoing process with data entered and checked as they become available allows timely recovery of errors and missing data.
