In addition, familiarity with a data source’s history and recording practices is important for making informed data source selection, study design choices, and interpretation of results. In this commentary, the authors discuss three studies that assessed different aspects of the quality and completeness of information contained in Clinical Practice Research Datalink (CPRD) Aurum compared to the well-established CPRD GOLD and to other linked data sources, with the aim to describe insights gained through these data quality assessments. Our findings support the view that CPRD Aurum and GOLD are both valuable tools for studies based on information recorded in primary care but should not be used without critical consideration of strengths and limitations. Further, use of linked data should be considered for some studies, after taking into account all relevant factors.Keywords: clinical practice research datalink, CPRD Aurum, CPRD GOLD, validation, data quality
