TL;DR: The GPRD has undergone many changes but remains the largest validated and most utilised primary care database in the UK and its use in pharmacoepidemiology stretches back many years with now over 800 original research papers.

TL;DR: An online user-focused system, underpinned by an innovative search algorithm, which enables users interactively to select suitable medical general practices based on two criteria: suitability of the patient base for the intended study (phenotyping) and measures of data quality.

TL;DR: This work has developed a protocol for measuring and monitoring data quality in primary care research databases, whereby practice-based data quality measures are tailored to the intended use of the data.

TL;DR: A framework for further improvement of existing methods of data quality assessment is developed, which shall extend a set of current quality measures for each practice and develop algorithms that will combine these measures into a smaller number of meaningful quality scores which will reflect different aspects of dataquality and can be measured over time.

TL;DR: The challenges and issues involved with measuring data quality in electronic health records for epidemiological and clinical research using the Clinical Practice Research Datalink as a model are discussed and a suggested framework is discussed to help ensure compatibility of data quality measures for different European Electronic Healthcare Records.
