Data linkage for healthcare research: basics and important considerations.

Abstract

There is increasing recognition of the benefits of robust data infrastructures, capacity building for a data informed society, and strategic policy and financial support to enable data integration (also known as data linkage). However, despite widespread availability of data, and recognition of the value of data linkage and investment in this area, data linkage continues to be complex, timely, and costly, and these elements are often underestimated by researchers. In this article, we introduce data linkage basics for Australian researchers and discuss important considerations for those embarking on healthcare research that utilises data linkage.
