This study investigates the reliability of the Manitoba Health Services Commission data bank from a variety of perspectives. Emphasizing diagnostic and surgical procedures, the research focuses on those areas in which problems exist and in which the data can be relied upon. Computerized comparisons are stressed, since they can provide cost-effective checks on data quality. One key to performing reliability studies inexpensively is finding information recorded independently: by separate individuals or organizations, at two different times, or in two or more data files. When a particular event has certain logical implications vis-à-vis another, inconsistencies can be located. Face sheet information and data on the performance of major surgical procedures were found to be reliably recorded in the Manitoba data bank. Collapsing ICD-8 diagnosis from medical claims into several categories proved much better than relying upon individual diagnoses. Problems in working with the data included difficulty in distinguishing between closely related surgical procedures and the underreporting of inhospital consultations and nonsurgical procedures.
本研究从多个角度调查了曼尼托巴省卫生服务委员会数据库的可靠性。该研究着重于诊断和外科手术程序，聚焦于存在问题以及数据可靠的领域。强调计算机化比较，因为它们可以对数据质量进行经济高效的检查。廉价开展可靠性研究的一个关键是找到独立记录的信息：由不同的个人或组织在两个不同时间记录，或记录在两个或更多数据文件中。当一个特定事件相对于另一个事件有某些逻辑关联时，就可以找出不一致之处。发现病历首页信息和主要外科手术程序执行情况的数据在曼尼托巴省数据库中记录可靠。将医疗索赔中的国际疾病分类第8版（ICD - 8）诊断合并为几类被证明比依赖个别诊断要好得多。处理这些数据时存在的问题包括难以区分密切相关的外科手术程序，以及住院会诊和非手术程序报告不足。
