We describe techniques for using the Computer-Stored Ambulatory Record (COSTAR) at the Massachusetts General Hospital to conduct a historical cohort study of the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on blood pressure control. A query language was used to identify patients satisfying clinical and data-availability criteria, to match these patients with clinically similar patients not exposed to NSAIDs, and to collect data from the COSTAR records of both groups of patients to determine any differences in outcome. We analyzed over 30,000 patient records to select 90 pairs of patients used in the study. This approach to clinical research uses data collected for purpose of patient care and so does not require the separate recording of patient data for clinical research. Using computer-based medical record systems with a query language allows selection and matching of patients using detailed demographic and clinical criteria. The ability to conduct such studies is an advantage of computer-based medical record systems over the paper record system.
我们描述了在马萨诸塞州综合医院使用计算机存储动态记录（COSTAR）进行一项关于非甾体抗炎药（NSAIDs）对血压控制影响的历史性队列研究的技术。使用一种查询语言来识别符合临床和数据可用性标准的患者，将这些患者与未接触NSAIDs的临床相似患者进行匹配，并从两组患者的COSTAR记录中收集数据以确定结果的任何差异。我们分析了超过30000份患者记录，以选择研究中使用的90对患者。这种临床研究方法使用为患者护理目的收集的数据，因此不需要为临床研究单独记录患者数据。使用带有查询语言的基于计算机的医疗记录系统允许根据详细的人口统计学和临床标准选择和匹配患者。进行此类研究的能力是基于计算机的医疗记录系统相对于纸质记录系统的一个优势。
