Data from over 2000 general practices
Produces weekly reports on communicable and respiratory diseases
The Clinical Informatics and Health Outcomes Research Group (CIHORG) is the home of the Oxford-Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC), one of the world oldest sentinel networks as well as involved in a wide range of observational and interventional research.
The RSC has been involved in the sentinel surveillance of respiratory disease, including influenza and COVID-19, for over 50 years. It is a long standing collaboration between the RCGP and the UK Health Security Agency (UKHSA). The scale of the RSC and it capabilities have expanded considerably since 2013, and described in the RSC’s 2023-2024 protocol and recent cohort profile. The lessons from the COVID-19 pandemic included the importance of our network recording high quality data, linking primary care data to virology and other data sources, and providing rapid data access, if we are to be ready for the next.
The RSC collected pseudonymised data from over 2,000 general practice network members and is used for disease surveillance and research. CIHORG has direct links to the RSC member practices who record high quality data, collect virology, serology and other samples, and recruit practices into research projects.
CIHORG is led by: Simon de Lusignan – Professor of Primary Care & Clinical Informatics, who can be contacted via Zahn Gowar. Our chief statistician is Mark Joy.
CIHORG is organised into two theme groups:
Surveillance and infectious disease epidemiology, led by Uy Hoang, with project management provided by Karina O’Neill and Dominic Dunn (laboratory links).
Cardiometabolic research is lead by Jose Ordonez-Mena, with project management provided by Filipa Ferreira.
