The Clinical Informatics and Health Outcomes Research Group from the Nuffield Department of Primary Care Health Sciences, University of Oxford is excited to invite healthcare professionals to join us and find out more about collaborating for research and surveillance. Our work directly benefits local communities and is actively contributing to improve patient care now and in the future. Our network of over 2,000 English practices contributes pseudonymised data that helps us monitor infections and diseases in real time. This data is essential for UK Health Security Agency (UKHSA) to manage outbreaks of flu, COVID-19, Respiratory Syncytial Virus (RSV), and more. Network practices can also broaden their research portfolio, by taking part in our approved research and clinical studies that advance primary care, benefiting patients nationwide.
