Electronic Health Records and Data Linkage

Epidemiological research depends crucially on high quality data. Electronic health records, often based on routinely-collected information, are an important source of data.

These records often come from different sources. Efficiently linking and anonymising them is crucial to fully exploit the potential these data resources offer to research for the benefit of patients and public health. 

Our work includes developing methods for analysing linked data, as well as identifying how linking available data sources can improve our ability to conduct research and help with health services planning.
