This review evaluates the quality of available administrative data in the Canadian provinces, emphasizing the information needed to create integrated systems. We explicitly compare approaches to quality measurement, indicating where record linkage can and cannot substitute for more expensive record re-abstraction. Forty-nine original studies evaluating Canadian administrative data (registries, hospital abstracts, physician claims, and prescription drugs) are summarized in a structured manner. Registries, hospital abstracts, and physician files appear to be generally of satisfactory quality, though much work remains to be done. Data quality did not vary systematically among provinces. Primary data collection to check place of residence and longitudinal follow-up in provincial registries is needed. Promising initial checks of pharmaceutical data should be expanded. Because record linkage studies were ''conservative'' in reporting reliability, the reduction of time-consuming record re-abstraction appears feasible in many cases. Finally, expanding the scope of administrative data to study health, as well as health care, seems possible for some chronic conditions. The research potential of the information-rich environments being created highlights the importance of data quality.
本综述评估了加拿大各省现有行政数据的质量，重点强调了创建综合系统所需的信息。我们明确比较了质量衡量方法，指出记录链接在哪些方面可以以及不能替代更昂贵的记录重新提取。以结构化方式总结了49项评估加拿大行政数据（登记处、医院摘要、医生索赔和处方药）的原始研究。登记处、医院摘要和医生档案的质量总体上似乎令人满意，不过仍有许多工作要做。各省之间的数据质量没有系统性差异。需要进行原始数据收集以核查省级登记处的居住地和纵向随访情况。应扩大对药品数据进行的有前景的初步核查。由于记录链接研究在报告可靠性方面较为“保守”，在许多情况下减少耗时的记录重新提取似乎是可行的。最后，对于某些慢性病，扩大行政数据用于研究健康以及医疗保健的范围似乎是可能的。正在创建的信息丰富环境的研究潜力凸显了数据质量的重要性。
