TLDR

The article discusses the organization and accuracy of Manitoba’s population registry and administrative database. The authors present a data management strategy and outline research opportunities using population registries and administrative data. They propose a framework for analyzing data accuracy within the registry and administrative database. The Manitoba registry and hospital claims are generally high quality, but hospital claims have reliability issues with secondary diagnoses and require aggregation for agreement with other methods.

Abstract

In this article the organization and accuracy of the population registry and administrative data base in Manitoba, Canada are discussed. The overall data management strategy and a framework for analyzing the accuracy of such data are presented. The generally high quality of the Manitoba registry file (necessary to track individuals over time) and the hospital claims is supported by comparisons with other data sources. Hospital claims' main quality problems concern the reliability of certain secondary diagnoses and the level of aggregation necessary for reasonable agreement with other data collection methods (such as chart reviews). Finally, some of the research possibilities associated with population registries and administrative data are outlined.
