The RCGP Research and Surveillance Centre (RSC) is an internationally renowned source of information, analysis and interpretation of primary care data. Established in 1957, the RSC is an active research and surveillance unit that collects and monitors data, in particular influenza, from over 500 practices across England.
In 2017 the RSC celebrated 50 years of weekly influenza surveillance and reporting, a landmark anniversary. The dataset is nationally representative, having only small differences with the national population, which have now been quantified and can be assessed for clinical relevance for specific studies. With twice weekly data extractions, the dataset is one of the most up to date in the UK.
